Subject: drm/i915: Make intel_digital_port_connected() work for any port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the missing port A handling to intel_digital_port_connected()
and also separate SPT from the CPT/LPT code a bit.

Subject: drm/doc: vblank cleanup

Unify and review everything, plus make sure it's all correct markup.
Drop the kernel-doc for internal functions. Also rework the overview
section, it's become rather outdated.

Unfortuantely the kernel-doc in drm_driver isn't rendered yet, but
that will change as soon as drm_driver is kernel-docified properly.

Also document properly that drm_vblank_cleanup is optional, the core
calls this already.

v2: Make it clear that cleanup happens in drm_dev_fini for drivers
with their own ->release callback (Thierry).

 Vertical Blanking
 =================
 
-Vertical blanking plays a major role in graphics rendering. To achieve
-tear-free display, users must synchronize page flips and/or rendering to
-vertical blanking. The DRM API offers ioctls to perform page flips
-synchronized to vertical blanking and wait for vertical blanking.
-
-The DRM core handles most of the vertical blanking management logic,
-which involves filtering out spurious interrupts, keeping race-free
-blanking counters, coping with counter wrap-around and resets and
-keeping use counts. It relies on the driver to generate vertical
-blanking interrupts and optionally provide a hardware vertical blanking
-counter. Drivers must implement the following operations.
-
--  int (\*enable_vblank) (struct drm_device \*dev, int crtc); void
-   (\*disable_vblank) (struct drm_device \*dev, int crtc);
-   Enable or disable vertical blanking interrupts for the given CRTC.
-
--  u32 (\*get_vblank_counter) (struct drm_device \*dev, int crtc);
-   Retrieve the value of the vertical blanking counter for the given
-   CRTC. If the hardware maintains a vertical blanking counter its value
-   should be returned. Otherwise drivers can use the
-   :c:func:`drm_vblank_count()` helper function to handle this
-   operation.
-
-Drivers must initialize the vertical blanking handling core with a call
-to :c:func:`drm_vblank_init()` in their load operation.
-
-Vertical blanking interrupts can be enabled by the DRM core or by
-drivers themselves (for instance to handle page flipping operations).
-The DRM core maintains a vertical blanking use count to ensure that the
-interrupts are not disabled while a user still needs them. To increment
-the use count, drivers call :c:func:`drm_vblank_get()`. Upon
-return vertical blanking interrupts are guaranteed to be enabled.
-
-To decrement the use count drivers call
-:c:func:`drm_vblank_put()`. Only when the use count drops to zero
-will the DRM core disable the vertical blanking interrupts after a delay
-by scheduling a timer. The delay is accessible through the
-vblankoffdelay module parameter or the ``drm_vblank_offdelay`` global
-variable and expressed in milliseconds. Its default value is 5000 ms.
-Zero means never disable, and a negative value means disable
-immediately. Drivers may override the behaviour by setting the
-:c:type:`struct drm_device <drm_device>`
-vblank_disable_immediate flag, which when set causes vblank interrupts
-to be disabled immediately regardless of the drm_vblank_offdelay
-value. The flag should only be set if there's a properly working
-hardware vblank counter present.
-
-When a vertical blanking interrupt occurs drivers only need to call the
-:c:func:`drm_handle_vblank()` function to account for the
-interrupt.
-
-Resources allocated by :c:func:`drm_vblank_init()` must be freed
-with a call to :c:func:`drm_vblank_cleanup()` in the driver unload
-operation handler.

Subject: drm/vblank: _ioctl posfix for ioctl handler

I alwasy get confused about drm_wait_vblank for a split second until I
realize it's the ioctl handler. Unconfuse me, and do it for the legacy
modeset vblank control ioctl too.

While at it also noticed that I misplaced the irq ioctl handler in the
internal header file.

Subject: drm/udl: Remove dummy busid callback

Since

commit ca8e2ad71013049bc88a10b11d83712bfe56cdd4
Author: Thierry Reding <treding@nvidia.com>
Date:   Fri Apr 11 15:23:00 2014 +0200

    drm: Introduce drm_dev_set_unique()

the ->set_busid callback is optional. On top of that the udl one isn't
really fully compliant with the drm uabi, but since only modesetting
ever binds to it (there's no 3d accel on udl) it doesn't matter.

Still, can't harm to aling and use the default used by everyone else.

Subject: drm: Remove drm_driver->set_busid hook

The only special-case is pci devices, and we can easily handle this in
the core. Do so and drop a pile of boilerplate from drivers.

From 10631d724deff712343d96dd3017cd323349f761 Mon Sep 17 00:00:00 2001

Subject: drm/pci: Deprecate drm_pci_init/exit completely

The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.

From bb2eaba6458ace16f7e3504de8788374cb42b43d Mon Sep 17 00:00:00 2001
From: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Wed, 31 May 2017 11:20:45 +0200
Subject: drm/doc: Improve ioctl/fops docs a bit more

I spotted a markup issue, plus adding the descriptions in drm_driver.
Plus a few more links while at it.

I'm still mildly unhappy with the split between fops and ioctls, but I
still think having the ioctls in the uapi chapter makes more sense. Oh
well ...

v2: Rebase.

v3: Move misplace hunk to the right patch.

Subject: drm: vc4: Use crtc->mode_valid() and encoder->mode_valid() callbacks

Now that we have a callback to check if crtc and encoder supports a
given mode we can use it in vc4 so that we restrict the number of
probed modes to the ones we can actually display.

Also, remove the mode_fixup() calls as these are no longer needed
because mode_valid() will be called before.

Subject: drm: More links for gamma support helpers

It's not obvious that when using the new color manager stuff you still
need to wire up the legacy helper to get legacy LUT support. Improve
this with more links. drm_crtc_funcs->gamma_set already explains this
properly.

Subject: drm/i915: Allow contexts to be unreferenced locklessly

If we move the actual cleanup of the context to a worker, we can allow
the final free to be called from any context and avoid undue latency in
the caller.

v2: Negotiate handling the delayed contexts free by flushing the
workqueue before calling i915_gem_context_fini() and performing the final
free of the kernel context directly
v3: Flush deferred frees before new context allocations

Subject: drm/i915: Enable rcu-only context lookups

Whilst the contents of the context is still protected by the big
struct_mutex, this is not much of an improvement. It is just one tiny
step towards reducing our BKL.

Subject: drm/i915: Wait for concurrent global resets to complete

If we enter i915_handle_error() a second time and a global reset is
already in progress, we can simply wait for completion of the first
reset. Currently we exit early prior to the actual reset being
performed -- the worst of both worlds!

v2: Plug into the existing reset_queue, and remember that kselftests is
playing games with I915_RESET_BACKOFF to prevent hangcheck from screwing
up.
v3: Rename to i915_reset_device to fit in better with i915_reset_engine

Subject: drm/i915: Look for active requests earlier in the reset path

And store the active request so that we only search for it once.

v2: Check for request completion inside _prepare_engine, don't use
ECANCELED, remove unnecessary null checks (Chris).

v3: Capture active requests during reset_prepare and store it the
engine hangcheck obj.

v4: Rename commit, change i915_gem_reset_request to just confirm the
active_request is still incomplete, instead of engine_stalled (Chris).

v5: With style; pass the active request to gem_reset_engine, keep single
return in reset_prepare_engine (Chris).

v6: Moved before reset-engine code appears (Chris)

Subject: drm/i915: Modify error handler for per engine hang recovery

This is a preparatory patch which modifies error handler to do per engine
hang recovery. The actual patch which implements this sequence follows
later in the series. The aim is to prepare existing recovery function to
adapt to this new function where applicable (which fails at this point
because core implementation is lacking) and continue recovery using legacy
full gpu reset.

A helper function is also added to query the availability of engine
reset. A subsequent patch will add the capability to query which type
of reset is present (engine -> full -> no-reset) via the get-param
ioctl.

It has been decided that the error events that are used to notify user of
reset will only be sent in case if full chip reset. In case of just
single (or multiple) engine resets, userspace won't be notified by these
events.

Note that this implementation of engine reset is for i915 directly
submitting to the ELSP, where the driver manages the hang detection,
recovery and resubmission. With GuC submission these tasks are shared
between driver and firmware; i915 will still responsible for detecting a
hang, and when it does it will have to request GuC to reset that Engine and
remind the firmware about the outstanding submissions. This will be
added in different patch.

v2: rebase, advertise engine reset availability in platform definition,
add note about GuC submission.
v3: s/*engine_reset*/*reset_engine*/. (Chris)
Handle reset as 2 level resets, by first going to engine only and fall
backing to full/chip reset as needed, i.e. reset_engine will need the
struct_mutex.
v4: Pass the engine mask to i915_reset. (Chris)
v5: Rebase, update selftests.
v6: Rebase, prepare for mutex-less reset engine.
v7: Pass reset_engine mask as a function parameter, and iterate over the
engine mask for reset_engine. (Chris)
v8: Use i915.reset >=2 in has_reset_engine; remove redundant reset
logging; add a reset-engine-in-progress flag to prevent concurrent
resets, and avoid dual purposing of reset-backoff. (Chris)
v9: Support reset of different engines in parallel (Chris)
v10: Handle reset-engine flag locking better (Chris)
v11: Squash in reporting of per-engine-reset availability.

From a1ef70e144534777965426393dcaa1721e908e83 Mon Sep 17 00:00:00 2001
From: Michel Thierry <michel.thierry@intel.com>

Subject: drm/i915: Add support for per engine reset recovery

This change implements support for per-engine reset as an initial, less
intrusive hang recovery option to be attempted before falling back to the
legacy full GPU reset recovery mode if necessary. This is only supported
from Gen8 onwards.

Hangchecker determines which engines are hung and invokes error handler to
recover from it. Error handler schedules recovery for each of those engines
that are hung. The recovery procedure is as follows,
 - identifies the request that caused the hang and it is dropped
 - force engine to idle: this is done by issuing a reset request
 - reset the engine
 - re-init the engine to resume submissions.

If engine reset fails then we fall back to heavy weight full gpu reset
which resets all engines and reinitiazes complete state of HW and SW.

v2: Rebase.
v3: s/*engine_reset*/*reset_engine*/; freeze engine and irqs before
calling i915_gem_reset_engine (Chris).
v4: Rebase, modify i915_gem_reset_prepare to use a ring mask and
reuse the function for reset_engine.
v5: intel_reset_engine_start/cancel instead of request/unrequest_reset.
v6: Clean up reset_engine function to not require mutex, i.e. no need to call
revoke/restore_fences and _retire_requests (Chris).
v7: Remove leftovers from v5, i.e. no need to disable irq, hold
forcewake or wakeup the handoff bit (Chris).
v8: engine_retire_requests should be (and it was) static; explain that
we have to re-init the engine after reset, which is why the init_hw call
is needed; check reset-in-progress flag (Chris).
v9: Rebase, include code to pass the active request to gem_reset_engine
(as it is already done in full reset). Remove unnecessary
intel_reset_engine_start/cancel, these are executed as part of the
reset.
v10: Rebase, use the right I915_RESET_ENGINE flag.
v11: Fixup to call reset_finish_engine even on error.

Subject: drm/i915: Add engine reset count to error state

Driver maintains count of how many times a given engine is reset, useful to
capture this in error state also. It gives an idea of how engine is coping
up with the workloads it is executing before this error state.

A follow-up patch will provide this information in debugfs.

v2: s/engine_reset/reset_engine/ (Chris)
    Define count as unsigned int (Tvrtko)

Subject: drm/i915: Export per-engine reset count info to debugfs

A new variable is added to export the reset counts to debugfs, this
includes full gpu reset and engine reset count. This is useful for tests
where they are expected to trigger reset; these counts are checked before
and after the test to ensure the same.

v2: Include reset engine count in i915_engine_info too (Chris).

Subject: drm/i915/selftests: reset engine self tests

Check that we can reset specific engines, also check the fallback to
full reset if something didn't work.

v2: rebase.
v3: use RESET_ENGINE_IN_PROGRESS flag.
v4: use I915_RESET_ENGINE flag.

Subject: drm/i915: Pass the right flags to i915_vma_move_to_active()

i915_vma_move_to_active() takes the execobject flags and not a boolean!
Instead of passing EXEC_OBJECT_WRITE we passed true [i.e.
EXEC_OBJECT_NEEDS_FENCE] causing us to start tracking the
vma->last_fence access and since we forgot to clear that on unbinding,
we caused a use-after-free.

Subject: drm/i915: Retire the VMA's fence tracker before unbinding

Since we may track unfenced access (GPU access to the vma that
explicitly requires no fence), vma->last_fence may be set without any
attached fence (vma->fence) and so will not be flushed when we call
i915_vma_put_fence(). Since we stopped doing a full retire of the
activity trackers for unbind, we need to explicitly retire each tracker.

Subject: drm/i915: Assert the vma's active tracking is clear before free

In looking at a use-after-free on Baytrail, it looks like the VMA's
activity tracking is suspect. Add some asserts to catch freeing the VMA
before we have decoupled all of its i915_gem_active trackers.

Subject: drm/i915: Cancel pending execlist tasklet upon wedging

Highly unlikely, but if the stop_machine() did suspend the tasklet, we
want to make sure that when it wakes it finds there is nothing to do.
Otherwise, it will loudly complain that the ELSP port tracking no longer
matches the hardware, and we will be mightly confused.

Subject: drm/vc4: Send a VBLANK event when disabling a CRTC

VBLANK events are missed when the CRTC is being disabled because the
driver does not wait till the end of the frame before stopping the
HVS and PV blocks. In this case, we should explicitly issue a VBLANK
event if there's one waiting.

Subject: drm: arcpgu: Use crtc->mode_valid() callback

Now that we have a callback to check if crtc supports a given mode
we can use it in arcpgu so that we restrict the number of probbed
modes to the ones we can actually display.

This is specially useful because arcpgu crtc is responsible to set
a clock value in the commit() stage but unfortunatelly this clock
does not support all the needed ranges.

Also, remove the atomic_check() callback as mode_valid() callback
will be called before.

Subject: drm/i915: Clear execbuf's vma backpointer upon release

commit 2889caa92321 ("drm/i915: Eliminate lots of iterations over the
execobjects array") jiggled around the error handling and replace a test
that we cleaned up properly after ourselves with an assertion. That
assertion failed because in the release function (moments after the
assertion) we were indeed forgetting to mark the vma as cleared. The
consequence was when testing an invalid relocation address, we would try
to release the vma twice (following the couple of attempts to verify the
address) and on the second release notice that the first release was
incomplete.

Testcase: igt/gem_reloc_overflow/invalid-address

Subject: drm/i915: pass the vma to insert_entries

The vma already contains most of the information we need for insertion.
But also in preparation for supporting huge gtt pages, it would be
useful to know the details of the vma, such that we can we can easily
determine the page sizes we are allowed to use when inserting into the
48b PPGTT.  This is especially true for 64K where we can't just
arbitrarily use it, since we require aligning/padding the vm space to
2M, which sometimes we can't enforce in the upper levels.

We have a few cases comparing pch_type directly. Let's just replace

Subject: drm/i915: Clean up some expressions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Write the '!(SNB||IVB)' checks in the CPT/PPT detections
as '!SNB && !IVB' to make it less messy looking, and clear out
some useless parens the from the virtualization PCH detection case.

Subject: drm/i915: Always use 9 bits of the LPC bridge device ID for PCH
 detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make the code less confusiong by always using the top 9 bits of the
LPC bridge device ID to detect the PCH type. We need to add a bit of
new code for WPT, and we need to adjust the KBP ID as well. All the
other pre-CNP IDs are fine as is.

The virtualization cases I think are fine. These P2X and P3X IDs
actually just look like the old PIIX4 and PIIX3 IDs to me. Not sure
why they're not called PIIX3/4 though. The qemu one has a comment
saying the full ID is 0x2918 which is fine with 9 bits.

v2: Keep the CNP ID as 0xa300 (DK)

Subject: drm/vc4: Allow vblank_disable_immediate on non-fw-kms. (v2)

With instantaneous high precision vblank timestamping
that updates at leading edge of vblank, the emulated
"hw vblank counter" from vblank timestamping which
increments at leading edge of vblank, and reliable
page flip execution and completion at leading edge
of vblank, we should meet the requirements for fast
vblank irq disable/enable.

Testing against rpi-4.12-rc5 Linux kernel with timing
measurement equipment indicates this works fine,
so allow immediate vblank disable for power saving.

For debugging in case of unexpected trouble, booting
with kernel cmdline option drm.vblankoffdelay=0
would keep vblank irqs on to approximate old behavior.

v2: Respin onto drm-misc-next, per Eric's suggestion.
    Drop !vc4->firmware_kms check, as the firmware_kms
    implementation does not exist in upstream.

Subject: drm/vc4: Use the atomic state's commit workqueue.

Now that we're using the atomic helpers for fence waits, we can use
the same codepath as drm_atomic_helper_commit() does for async,
getting rid of our custom vc4_commit struct.

Subject: drm/rockchip: dw_hdmi: introduce the VPLL clock setting

For RK3399 HDMI, there is an external clock need for HDMI PHY,
and it should keep the same clock rate with VOP DCLK.

VPLL have supported the clock for HDMI PHY, but there is no
clock divider bewteen VPLL and HDMI PHY. So we need to set the
VPLL rate manually in HDMI driver.

Subject: drm/rockchip: dw_hdmi: introduce the pclk for grf

For RK3399's GRF module, if we want to operate the graphic related grf
registers, we need to enable the pclk_vio_grf which supply power for VIO
GRF IOs, so it's better to introduce an optional grf clock in driver.

disable the disable timer). Hence we don't need this here and can
remove it.

Almost right but still racy, it's called before the interrupts are
uninstalled. So let's just drop it.

Subject: drm/i915: Set PWM divider to match desired frequency in vbt

Read desired PWM frequency from panel vbt and calculate the
value for divider in DPCD address 0x724 and 0x728 to have
as many bits as possible for PWM duty cyle for granularity of
brightness adjustment while the frequency divisor is still
within 25% of the desired value.

Subject: drm/i915: Add heuristic to determine better way to adjust brightness

Add heuristic to decide that AUX or PWM pin should use for
backlight brightness adjustment and modify i915 param description
to have auto, force disable, and force enable.

The heuristic to determine that using AUX pin is better than using
PWM pin is that the panel support any of the feature list here.
- Regional backlight brightness adjustment
- Backlight PWM frequency set
- More than 8 bits resolution of brightness level
- Backlight enablement via AUX and not by BL_ENABLE pin

Subject: drm/vgem: Pin our pages for dmabuf exports

When the caller maps their dmabuf and we return an sg_table, the caller
doesn't expect the pages beneath that sg_table to vanish on a whim (i.e.
under mempressure). The contract is that the pages are pinned for the
duration of the mapping (from dma_buf_map_attachment() to
dma_buf_unmap_attachment). To comply, we need to introduce our own
vgem_object.pages_pin_count and elevate it across the mapping. However,
the drm_prime interface we use calls drv->prime_pin on dma_buf_attach
and drv->prime_unpin on dma_buf_detach, which while that does cover the
mapping is much broader than is desired -- but it will do for now.

v2: also hold the pin across prime_vmap/vunmap

Subject: drm/i915: Break modeset deadlocks on reset

Trying to do a modeset from within a reset is fraught with danger. We
can fall into a cyclic deadlock where the modeset is waiting on a
previous modeset that is waiting on a request, and since the GPU hung
that request completion is waiting on the reset. As modesetting doesn't
allow its locks to be broken and restarted, or for its *own* reset
mechanism to take over the display, we have to do something very
evil instead. If we detect that we are stuck waiting to prepare the
display reset (by using a very simple timeout), resort to cancelling all
in-flight requests and throwing the user data into /dev/null, which is
marginally better than the driver locking up and keeping that data to
itself.

This is not a fix; this is just a workaround that unbreaks machines
until we can resolve the deadlock in a way that doesn't lose data!

v2: Move the retirement from set-wegded to the i915_reset() error path,
after which we no longer any delayed worker cleanup for
i915_handle_error()
v3: C abuse for syntactic sugar
v4: Cover all waits with the timeout to catch more driver breakage

Subject: iio: light: tsl2563: use correct event code

The TSL2563 driver provides three iio channels, two of which are raw ADC
channels (channel 0 and channel 1) in the device and the remaining one
is calculated by the two.  The ADC channel 0 only supports programmable
interrupt with threshold settings and this driver supports the event but
the generated event code does not contain the corresponding iio channel
type.

This is going to change userspace ABI.  Hopefully fixing this to be
what it should always have been won't break any userspace code.

Subject: iio: pressure: st_pressure_core: disable multiread by default for
 LPS22HB

Set multiread variable to false for LPS22HB pressure sensor since
it is already enabled in CTRL_REG2. Previous configuration does not
cause any issue in I2C communication since SUB Msb has no meaning
whereas it breaks register address in SPI communication

Subject: drm/hibmc: Drop drm_vblank_cleanup

So this seems to be the first driver that does it the right way round,
so fix it up by calling drm_atomic_helper_shutdown instead. We need to
do that before the last kms user is gone (fbdev emulation), but before
we start shutting down hw stuff like interrupts.

Again stopping the vblank before uninstalling the irq handler is kinda
the wrong way round, but the fb_off stuff should take care of
disabling the dsiplay at least in most cases. So drop the
drm_vblank_cleanup code since it's not really doing anything, it looks

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When we read the VBT t11_t12 value for panel power cycle delay,
it is a zero based value so we need to 100ms to that. And then it
needs to be multiplied by 10 to store it in 100usecs unit same as
SW VBT.

v3:
* Add it as part of series
v2:
* Change the VBT value instead of HW readout and pp div (Ville Syrjala)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now the VBT.seq->t11_t12 value adds 100ms to both Gen9_LP
as well as non Gen9_LP cases so no need to special case
and do -1 during HW readout and +1 during pp_div write
for Gen9_LP/CNP case.

Subject: drm/atomic-helper: Simplify commit tracking locking

The crtc->commit_lock only protects commit_list and commit_entry. If
we chase the pointer from the drm_atomic_state update structure, then
we don't need any locks (since we hold a reference already).

Simplify the locking accordingly.

Noticed while reviewing a patch from Boris.

Subject: drm/i915: Disable MSI for all pre-gen5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have pretty clear evidence that MSIs are getting lost on g4x and
somehow the interrupt logic doesn't seem to recover from that state
even if we try hard to clear the IIR.

Disabling IER around the normal IIR clearing in the irq handler isn't
sufficient to avoid this, so the problem really seems to be further
up the interrupt chain. This should guarantee that there's always
an edge if any IIR bits are set after the interrupt handler is done,
which should normally guarantee that the CPU interrupt is generated.
That approach seems to work perfectly on VLV/CHV, but apparently
not on g4x.

MSI is documented to be broken on 965gm at least. The chipset spec
says MSI is defeatured because interrupts can be delayed or lost,
which fits well with what we're seeing on g4x. Previously we've
already disabled GMBUS interrupts on g4x because somehow GMBUS
manages to raise legacy interrupts even when MSI is enabled.

Since there's such widespread MSI breakahge all over in the pre-gen5
land let's just give up on MSI on these platforms.

Seqno reporting might be negatively affected by this since the legcy
interrupts aren't guaranteed to be ordered with the seqno writes,
whereas MSI interrupts may be? But an occasioanlly missed seqno
seems like a small price to pay for generally working interrupts.

From 228d2af1b723deedee38f03d144b7d25b39f6f86 Mon Sep 17 00:00:00 2001
From: Don Hiatt <don.hiatt@intel.com>

Subject: IB/hfi1: Separate input/output header tracing

Calls to trace incoming packets will now receive the packet
context as parameter. This enables trace support for future
packet types.

Header trace output is in the format <field>:<value>
which makes parsing easier.

input_ibhdr trace before change:
<idle>-0     [001] d.h.  5904.250925: input_ibhdr: [0000:05:00.0] vl 0
lver 0 sl 0 lnh 2,LRH_BTH dlid 0002 len 18 slid 0001 op

a 0 psn 0x000001b2 deth qkey 0x80010000 sqpn 0x000001

input_ibhdr trace after change:
<idle>-0     [001] d.h.  6655.714488: input_ibhdr: [0000:05:00.0] (IB)

Subject: IB/hfi1: Setup common IB fields in hfi1_packet struct

We move many common IB fields into the hfi1_packet structure and
set them up in a single function. This allows us to set the fields
in a single place and not deal with them throughout the driver.

Subject: IB/rdmavt: Compress adjacent SGEs in rvt_lkey_ok()

SGEs that are contiguous needlessly consume driver dependent TX resources.

The lkey validation logic is enhanced to compress the SGE that ends
up in the send wqe when consecutive addresses are detected.

The lkey validation API used to return 1 (success) or 0 (fail).

The return value is now an -errno, 0 (compressed), or 1 (uncompressed).  A
additional argument is added to pass the last SQE for the compression.

Loopback callers always pass a NULL to last_sge since the optimization is
of little benefit in that situation.

Subject: IB/hfi1: Don't remove RB entry when not needed.

An RB tree is used for the SDMA pinning cache. Cache
entries are extracted and reinserted from the tree
in case the address range for it changes. However,
if the address range for the entry doesn't change,
deleting the entry from the RB tree is not necessary.

This affects performance since the tree needs to be
rebalanced for each insertion, and this happens in
the hot path. Optimize RB search by not removing
entries when it's not needed.

Subject: IB/hfi1: Optimize cachelines for user SDMA request structure

The current user SDMA request structure layout has holes.
The cachelines can be reduced to improve cacheline trading.
Separate fields in the following categories: mostly read,
writable and shared with interrupt.

Subject: IB/hfi1: Remove atomic SDMA_REQ_SEND_DONE bit operation

The atomic SDMA_REQ_SEND_DONE bit is set by the
process-level code, and then the same process-level
code uses the bit to test that all packets have been
submitted incurring a costly atomic read.

Use a bool type with a READ_ONCE/WRITE_ONCE
pairing for this bit, and use the same condition that
is used to set the bit to test that all packets have
been submitted.

Subject: IB/hfi1: Remove atomic SDMA_REQ_HAS_ERROR bit operation

Atomic bit tests are used to single errors and the
completion of request submissions. These operations
don't need to be atomic and show to be expensive on
the profile.

Replace each atomic bit operation with a bool type
and a READ_ONCE/WRITE_ONCE pairing.

Subject: IB/hfi1: Ensure dd->gi_mask can not be overflowed

As the code stands today the array access in remap_intr() is OK. To
future proof the code though we should explicitly check to ensure the
index value is not outside of the valid range. This is not a straight
forward calculation so err on the side of caution.

Subject: IB/hfi1: Remove subtraction of uninitialized value

In process_receive_packet the packet header field is used to calculate
the length of the packet. However this is not necessarily setup. In fact
only if the ECN prescan is enabled will the packet header be valid at
this point.

The code works as is because we do not do anything with the packet
length at this point in the packet processing. The length and header are
setup correctly in hfi1_setup_ib_header which is called by the following
sequence:

process_receive_packet()
-> rhf_receieve_function_map[]()
--> process_receive_ib()
---> hfi1_setup_9B_packet()
----> hfi1_setup_ib_header()

Subject: IB/core: Allow QP state transition from reset to error

Playing with IP-O-IB interface can trigger a warning message:
"ib0: Failed to modify QP to ERROR state" to be logged.
This happens when the QP is in IB_QPS_RESET state and the stack
is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop().

According to the IB spec, Table 91 - "QP State Transition Properties"
it looks like the transition from reset to error is valid:

Transition: Any State to Error
Required Attributes: None
Optional Attributes: None allowed
Actions: Queue processing is stopped. Work Requests pending or in
process are completed in error, when possible.

This patch allows the transition and quiets the message.

From 13d84914db56c1afd1c9bf4f41e9bf91f061a7dd Mon Sep 17 00:00:00 2001
From: Dennis Dalessandro <dennis.dalessandro@intel.com>

Subject: IB/hfi1,qib: Do not send QKey trap for UD qps

According to IBTA spec a QKey violation should not result in a bad qkey
trap being triggered for UD queue pairs. Also since it is a silent error
we do not increment the q_key violation or the dropped packet counters.

for discrete cards. It will happen when reading from EPROM fails.
EFI variables should not be queried for platform configuration
in any scenario.

This patch adds a trace for putting a TID and
for writing the RcvArray CSR.

The CSR access template can be easily extended for additional

Subject: IB/hfi1: Initialize TID lists to avoid crash on cleanup

The expected receive lists (tid_xxx_list) are not initialized until
late in the receive context initialization.  If an error happens
before the initialization, a NULL pointer access will occur during
cleanup.

Initialized the lists sooner rather than later to avoid this Oops:

Subject: IB/hfi1: Resolve kernel panics by reference counting receive contexts

Base receive contexts can be used by sub contexts.  Because of this,
resources for the context cannot be completely freed until all sub
contexts are done using the base context.

Introduce a reference count so that the base receive context can be
freed only when all sub contexts are done with it.

Use the provided function call for setting default send context
integrity rather than the manual method.

The cleanup path does not set all variables back to NULL after freeing
resources.  Since the clean up code can get called more than once,
(e.g. during context close and on the error path), it is necessary to
make sure that all the variables are NULLed.

Possible crash are:

Subject: IB/hfi1: Handle missing magic values in config file

Driver does not check whether proper configuration file exist in EPROM,
and treats empty partition as possible valid configuration, preventing
fallback to default firmware. Change EPROM read function to treat
missing magic number as read error.

Subject: drm/core: Fail atomic IOCTL with no CRTC state but with signaling.

Problem : While running IGT kms_atomic_transition test suite i encountered
a hang in drmHandleEvent immediately following  an atomic_commit.
After dumping the atomic state I relized that in this case there was
not even one CRTC attached to the state and only disabled
planes. This probably due to a commit which hadn't changed any property
which would require attaching crtc state. This means drmHandleEvent
will never wake up from read since without CRTC in atomic state
the event fd will not be signaled.

Fix: Protect against this issue by failing atomic_commit early in
drm_mode_atomic_commit where such probelm can be identified.

v2:
Fix typos and extra newlines.

Subject: drm/i915: Cancel pending execlists irq handler upon idling

Due to the slight asynchronicity in handling the execlists interrupts
(i.e. we defer the work to a handler that may consume more than one
interrupt event), when the engine is idle we may still have an irq
tasklet queued (especially when it has been deferred to a ksoftirqd).
At the beginning of the tasklet, we assert that we do hold a device
wakeref for the access we are about to perform. This assumes that when
we idle and release the GT wakeref, all execlists work has been
completed (since the elsp tracking says the hw is idle). However, there
may still be a tasklet queued, so as we mark the engine idle, also
cancel any pending tasklet.

Subject: drm/vblank: Unexport drm_vblank_cleanup

There's no reason for drivers to call this, and all the ones I've
removed looked very fishy:
- Proper quiescenting of the vblank machinery should be done by
  calling drm_crtc_vblank_off(), which is best done by shutting down
  the entire display engine with drm_atomic_helper_shutdown.

- Releasing of allocated memory is done by the core already, it calls
  drm_vblank_cleanup as a fallback.

- drm_vblank_cleanup also has checks for drivers which forget to clean
  up vblank interrupts.

This essentially reverts

    drm: Avoid calling vblank function is vblank wasn't initialized

which was done to fix a bug in radeon code with msi interrupts:

commit 003e69f9862bcda89a75c27750efdbc17ac02945
Author: Jerome Glisse <jglisse@redhat.com>
Date:   Thu Jan 7 15:39:14 2010 +0100

    drm/radeon/kms: Don't try to enable IRQ if we have no handler installed

Afaict from digging around in old code, this was needed to avoid
blowing up in the ums fallback, and has stopped serving it's purpose
long ago - if irq init fails, the driver fails to load, and there's
really no way to blow up anymore.

Long story short, this was most likely a small ums compat/fallback
hack that became a thing of it's own and got cargo-cult duplicated all
over the drm codebase for essentially no gain at all.

v2: Mention that for drivers with a ->release callback cleanup is
handled by drm_dev_fini() (Thierry).

Subject: drm: arcpgu: Remove CRTC .prepare() helper operation

The CRTC helper .prepare() operation is legacy code, the atomic helpers
prefer the .disable() operation. As the arcpgu driver implements the
.disable() and .prepare() operations identicallly, .prepare() can be
removed.

The CRTC .dpms() helper operation is called by the atomic helpers only
when no .prepare(), .atomic_disable() or .disable() operation is
provided. As the qxl driver provides a .disable() operation, the .dpms()
operation is unused and can be removed.

Subject: drm/i915: Drop flushing of the object free list/worker from
 i915_gem_suspend

i915_gem_suspend() is called from all of our finalization paths
(suspend, hibernate, unload). i915_gem_drain_freed_objects() adds an
arbitrary delay as it uses an rcu_barrier() to ensure that there are no
more freed objects in flight, and this delay causes a large amount of
variability in suspend timings. For S3 suspend, we do not need to free
pages as doing so does not impact at all upon the system in its
suspended state, unlike S4 hibernation where we do want the hibernation
image to be as small as possible. Therefore we can forgo waiting inside
i915_gem_suspend(), so long as we ensure that we do cleanup before
unload (see i915_gem_load_cleanup()) and prefer to reap our objects
prior to hibernation (see i915_gem_freeze()).

Removing the rcu_barrier() from i915_gem_suspend() improves S3 latency
by about 30ms on Skylake (ymmv).

Subject: drm/i915: Avoid keeping waitboost active for signaling threads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Once a client has requested a waitboost, we keep that waitboost active
until all clients are no longer waiting. This is because we don't
distinguish which waiter deserves the boost. However, with the advent of
fence signaling, the signaler threads appear as waiters to the RPS
interrupt handler. So instead of using a single boolean to track when to
keep the waitboost active, use a counter of all outstanding waitboosted
requests.

At this point, I have removed all vestiges of the rate limiting on
clients. Whilst this means that compositors should remain more fluid,
it also means that boosts are more prevalent. See commit b29c19b64528
("drm/i915: Boost RPS frequency for CPU stalls") for a longer discussion
on the pros and cons of both approaches.

A drawback of this implementation is that it requires constant request
submission to keep the waitboost trimmed (as it is now cancelled when the
request is completed). This will be fine for a busy system, but near
idle the boosts may be kept for longer than desired (effectively tens of
vblanks worstcase) and there is a reliance on rc6 instead.

v2: Remove defunct rps.client_lock

Subject: drm/gma500: remove an unneeded NULL check

"connector" is the list iterator and it can't be NULL.  It causes a
static checker warning because we dereference the iterator to get the
next item in the list.  Let's remove this check.

Subject: drm/i915: reintroduce VLV/CHV PFI programming power domain workaround
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are still cases on these platforms where an attempt is made to
configure the CDCLK while the power domain is off, like when coming back
from a suspend.  So the workaround below is still needed.

This effectively reverts commit 63ff30442519 ("drm/i915: Nuke the
VLV/CHV PFI programming power domain workaround").

Subject: drm/i915: Avoid undefined behaviour of "u32 >> 32"

When computing a hash for looking up relocation target handles in an
execbuf, we start with a large size for the hashtable and proceed to
halve it until the allocation succeeds. The final attempt is with an
order of 0 (i.e. a single element). This means that we then pass bits=0
to hash_32() which then computes "hash >> (32 - 0)" to lookup the single
element. Right shifting a value by the width of the operand is
undefined, so limit the smallest hash table we use to order 1.

v2: Keep the retry allocation flag for the final pass

Subject: drm/i915/cfl: Fix Workarounds.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During the review of Coffee Lake workarounds Mika pointed out
that WaDisableKillLogic and GEN9_DISABLE_OCL_OOB_SUPPRESS_LOGIC
should be removed from CFL and with that I should carry the rv-b.

However when doing the v2 I removed another Workaround that should
remain because although not mentioned by spec the history of hangs
around it advocates on its favor.

On some follow-up patches I continued operating on the wrong
workardound, but Ville noticed that, so here is the fix for the
current CFL code that is upstream already.

Subject: dma-buf/sw-sync: Fix the is-signaled test to handle u32 wraparound

Use the canonical __dma_fence_is_later() to compare the fence seqno
against the timeline seqno to check if the fence is signaled.

Subject: dma-buf/sw-sync: sync_pt is private and of fixed size

Since sync_pt is only allocated from a single location and is no longer
the base class for fences (that is struct dma_fence) it no longer needs
a generic unsized allocator.

Subject: dma-buf/sw-sync: Fix locking around sync_timeline lists

The sync_pt were not adding themselves atomically to the timeline lists,
corruption imminent.  Only a single list is required to track the
unsignaled sync_pt, so reduce it and rename the lock more appropriately
along with using idiomatic names to distinguish a list from links along
it.

v2: Prevent spinlock recursion on free during create (next patch) and
fixup crossref in kerneldoc

Subject: dma-buf/sw-sync: Use an rbtree to sort fences in the timeline

Reduce the list iteration when incrementing the timeline by storing the
fences in increasing order.

v2: Prevent spinlock recursion on free during create
v3: Fixup rebase conflict inside comments that escaped the compiler.

Subject: drm: Add old state pointer to CRTC .enable() helper function

The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.

While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

From 64581714b58bc3e16ede8dc37a025c3aa0e0eef1 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
Date: Fri, 30 Jun 2017 12:36:45 +0300
Subject: drm: Convert atomic drivers from CRTC .disable() to .atomic_disable()

The CRTC .disable() helper operation is deprecated for atomic drivers,
the new .atomic_disable() helper operation being preferred. Convert all
atomic drivers to .atomic_disable() to avoid cargo-cult use of
.disable() in new drivers.

Subject: iio: accel: bmc150: Add support for BOSC0200 ACPI device id

Add support for the BOSC0200 ACPI device id used on some x86 tablets.
note driver_data is not set to a specific model, driver_data is not
used anyways (instead detection is done on the chip_id reg) and the
2 tablets with a BOSC0200 ACPI device id I've have 2 different chips,
one has a BMA250E, the other a BMA222E.

Subject: iio: gyro: st_gyro: fix L3GD20H support

Add proper support for L3GD20H gyroscope sensor. In particular:
- use L3GD20H as device name instead of L3GD20
- fix available full scales
- fix available sample frequencies

Note that the original patch listed first below introduced broken support for
this part.  The second patch drops the support as it didn't work.

This new patch brings in working support.

Fixes: 9444a300c2be (IIO: Add support for L3GD20H gyroscope)

Subject: iio: adc: Fix polling of INA219 conversion ready flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While the INA226 has a conversion ready flag (CVRF) in the R/W Mask/Enable
register with read-to-clear semantics, the corresponding bit of the INA219
(CNVR) is part of the bus voltage register. The flag is cleared by reading
the power register.

Subject: iio: light: tcs3472: fix ATIME register write

The integration time is controlled by the ATIME register only.  However,
this register is written by i2c_smbus_write_word_data() in write_raw().

We actually don't need to write a subsequent register.  So just use
i2c_smbus_write_byte_data() instead.

Enable multiread by default for LIS3MDL since using I2C interface
the subaddr Msb is used to automatically increase the slave address
during multiple data read/write. In the same way, using SPI interface,
bit 1 in register address is used to enable auto-increment of the slave
address in multiple read/write.

Subject: iio: adc: at91-sama5d2_adc: add support for suspend/resume
 functionality

Added support for suspend/resume functionality for the ADC IP
in sama5d2 SoC.
In order to enter Suspend to ram mode (backup + self refresh mode for
memory), in which the ADC IP is no longer powered, we need to reset the
pins to default state, for the scenario when they are also used for I2C
bus to communicate with the PMIC.
On resume, we need to reconfigure the ADC IP registers and reconfigure the
trigger registers in the case when the suspend procedure is done while
sysfs has the buffer and trigger enabled.
In the case the suspend happens exactly during a software triggered
conversion, the request will time out, because we reset and power down
the ADC.

Subject: iio: adc: mcp3422: Checking for error on probe

Some part of the configuration are not touched after the probe
and if something goes wrong on writing the initial one,
the chip will misbehave.
Adding an error checking ensures that the inital configuration will
be written correctly. Moreover ensures that a sensible configuration
will be saved in driver data and used subsequently as intended.

Subject: iio: magnetometer: Only declare ACPI table when ACPI is enable

Don't inflate the kernel size with data that isn't used. The conditional
declaration also fixes the following warning when building with clang:

drivers/iio/magnetometer/ak8975.c:704:36: error: variable 'ak_acpi_match'
  is not needed and will not be emitted

Subject: drm/atomic: initial support for asynchronous plane update
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In some cases, like cursor updates, it is interesting to update the
plane in an asynchronous fashion to avoid big delays. The current queued
update could be still waiting for a fence to signal and thus block any
subsequent update until its scan out. In cases like this if we update the
cursor synchronously through the atomic API it will cause significant
delays that would even be noticed by the final user.

This patch creates a fast path to jump ahead the current queued state and
do single planes updates without going through all atomic steps in
drm_atomic_helper_commit(). We take this path for legacy cursor updates.

For now only single plane updates are supported, but we plan to support
multiple planes updates and async PageFlips through this interface as well
in the near future.

v6:	- move check code to drm_atomic_helper.c (Daniel Vetter)

v5:
	- improve comments (Eric Anholt)

v4:
	- fix state->crtc NULL check (Archit Taneja)

v3:
	- fix iteration on the wrong crtc state
	- put back code to forbid updates if there is a queued update for
	the same plane (Ville Syrjälä)
	- move size checks back to drivers (Ville Syrjälä)
	- move ASYNC_UPDATE flag addition to its own patch (Ville Syrjälä)

v2:
	- allow updates even if there is a queued update for the same
	plane.
        - fixes on the documentation (Emil Velikov)
        - unconditionally call ->atomic_async_update (Emil Velikov)
        - check for ->atomic_async_update earlier (Daniel Vetter)
        - make ->atomic_async_check() the last step (Daniel Vetter)
        - add ASYNC_UPDATE flag (Eric Anholt)
        - update state in core after ->atomic_async_update (Eric Anholt)
	- update docs (Eric Anholt)

Subject: drm/bochs: switch fb_ops over to use drm_fb_helper_cfb helpers

The current drm_fb_helper_sys helpers referenced in fb_ops assume that the
video memory is in system RAM. This is not the case for sparc which uses direct
physical memory accesses for IO memory and causes the bochs_drm module to panic
immediately upon startup as it tries to initialise the framebuffer.

Switching fb_ops over to use the drm_fb_helper_cfb helpers ensures that the
correct accesses are used on sparc, fixing the panic and allowing the
bochs_drm module to function under qemu-system-sparc64.

Subject: drm/etnaviv: don't trigger OOM killer when page allocation fails

GPU buffers can be quite large, so userspace is expected to deal with
allocation failure. Don't trigger the OOM killer when page allocation for
the GEM objects fails, as this opens an easy possiblity for unprivileged
applications to DOS the system,a s the shmem pages are not fully accounted
to the allocating process.

Subject: drm/etnaviv: populate GEM objects on cpu_prep

CPU prep is the point where we can reasonably return an error to userspace
when something goes wrong while populating the object. If we leave the
object unpopulated at this point, the allocation will happen in the
fault handler when userspace accesses the object through the mmap space,
where we don't have any other option than to OOM the system.

Subject: drm/i915: Prevent kernel panic when reading/writing compliance
 debugfs files, v2.

When reading all debugfs files on a system with DP-MST the kernel panics
on a null pointer dereference because intel_dp is null for a DP-MST
connector. Detect this case and skip those connectors.

Also fix the write for the DP compliance file in the same way.

Changes since v1:
- Fix i915_displayport_test_active_write too. (DK)

Remove drm_mode_config_fb, I don't see the point of it.
To make it clear that it's ok to use plane->fb directly,
move up drm_drv_uses_atomic_modeset so the code is skipped for atomic
drivers that require plane_state->fb.

Instead of passing the root node, pass NULL, which does exactly the same:

If the GIC cannot map an IRQ via irq_domain_ops->alloc(), it doesn't
return an error code.  This can cause a problem with drivers, where
it thinks it has successfully got an IRQ for the device, but requesting
the same ends up failure with -ENOSYS (as the IRQ's chip is not set).

Subject: drm/i915/fbdev: Check for existence of ifbdev->vma before operations

Commit fabef825626d ("drm/i915: Drop struct_mutex around frontbuffer
flushes") adds a dependency to ifbdev->vma when flushing the framebufer,
but the checks are only against the existence of the ifbdev->fb and not
against ifbdev->vma. This leaves a window of opportunity where we may
try to operate on the fbdev prior to it being probed (thanks to
asynchronous booting).

In Gen9 platform Interlaced fetch mode doesn't support following plane
configuration:
 - Y/Yf tiling
 - 90/270 rotation
 - YUV420 hybrid planar source pixel formats.

This patch adds check to fail the flip if any of the above configuration
is requested.

Changes since V1:
 - handle checks in intel_plane_atomic_check_with_state (ville)
 - takeout plane scaler checks combile with pipe scaler in next patch
Changes since V2:
 - No need to check for NV12 as it need scaling, so it will be rejected
   by scaling check (ville)

Subject: drm/i915/edp: Add a T12 panel delay quirk to fix DP AUX CH timeouts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes the DP AUX CH timeouts observed during CI IGT
tests thus fixing the CI failures. This is done by adding a
quirk for a particular PCI device that requires the panel power
cycle delay (T12) to be set to 800ms which is 300msecs more than
the minimum value specified in the eDP spec. So a quirk is
implemented for that specific PCI device.

v4:
* Add Bugzilla links for FDO bugs in the commit message (Ville, Jani)
v3:
* Change some comments, specify the delay as 800 * 10 (Ville)
v2:
* Change the function and variable names to from PPS_T12_
to _T12 since it is a T12 delay (Clint)

Subject: iio: adc: sun4i-gpadc-iio: fix unbalanced irq enable/disable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When initializing interrupts, the devm_request_any_context_irq will
enable them right away. An atomic flag was set in sun4i_irq_init and read
in the interrupt handler to make sure no unwanted interrupts were
handled. If an unwanted interrupt occurred, the handler would disable
the irq and return IRQ_HANDLED. However, at the end of sun4i_irq_init,
the irq would be disabled as well, resulting in an unbalanced enable
(since there are more disables than enables, the code enabling the
interrupt would never be called).

When reading the ADC or the temperature, the respective irq would be
enabled in the read function and disabled in the irq handler. In the
read function, we would wait for a completion (with a timeout) that will
be set in the irq handler. However, if the completion is never set or if
the wait for completion times out, the irq would not be disabled in the
read function resulting in an unbalanced enable once the read function
is called again (since there are 2+ enables for no disable).

Moving disable_irq from the irq handler to the read function get rid of
these two cases of unbalanced enable.

Fixes: d1caa9905538 ("iio: adc: add support for Allwinner SoCs ADC")

Subject: iio: adc: Revert "axp288: Drop bogus AXP288_ADC_TS_PIN_CTRL register
 modifications"

Inheriting the ADC BIAS current settings from the BIOS instead of
hardcoding then causes the AXP288 to disable charging (I think it
mis-detects an overheated battery) on at least one model tablet.

So lets go back to hard coding the values, this reverts
commit fa2849e9649b ("iio: adc: axp288: Drop bogus
AXP288_ADC_TS_PIN_CTRL register modifications"), fixing charging not
working on the model tablet in question.

The exact cause is not fully understood, hence the revert to a known working
state.

Subject: iio: light: rpr0521 triggered buffer

Set up and use triggered buffer if there is irq defined for device in
device tree. Trigger producer triggers from rpr0521 drdy interrupt line.
Trigger consumer reads rpr0521 data to scan buffer.
Depends on previous commits of _scale and _offset.

Subject: x86/mm: Stop calling leave_mm() in idle code

Now that lazy TLB suppresses all flush IPIs (as opposed to all but
the first), there's no need to leave_mm() when going idle.

This means we can get rid of the rcuidle hack in
switch_mm_irqs_off() and we can unexport leave_mm().

This also removes acpi_unlazy_tlb() from the x86 and ia64 headers,
since it has no callers any more.

    drm: Add top level Kconfig option for DRM fbdev emulation

this is properly handled using dummy functions. This essentially
undoes

    drm/i915: fix build without fbde

v2: We also need to drop the #ifdef from headers. Seems like a small
price to pay for slightly cleaner code.

From: Thierry Reding <treding@nvidia.com>
Date: Tue, 4 Jul 2017 17:18:23 +0200
Subject: drm/fb-helper: Add top-level lock

Introduce a new top-level lock for the FB helper code. This will allow
better locking granularity and avoid the need to abuse modeset locking
for this purpose instead.

This patch just adds the new lock everywhere we currently grab
mode_config->mutex (explicitly, or through drm_modeset_lock_all).
Follow-up patches will push the kms locking down into only the places
that need it.

v2:
- use lockdep_assert_held
- use drm_fb_helper_for_each_connector where possible
- use the new top-level lock consistently, i.e. in all the places
  we're currently acquiring mode_config.mutex.
- small polish to the kerneldoc

That function only needs to take the individual crtc locks, not all
the kms locks. Push down the locking and then minimize it.

Subject: drm/fb-helper: Drop locking from the vsync wait ioctl code

Like with the drm-native vblank wait ioctl we can entirely rely on the
spinlocks in drm_vblank.c, no need at all to take expensive mutexes.
The only reason we had to take mode_config.mutex was to protect the
fbdev helper's data-structures, but that's now done by
fb_helper->lock.

For the legacy path we'll keep drm_modeset_lock_all, for the atomic
one we drop the use of the magic implicit context and wire it up
properly.

Subject: drm/fb-helper: Stop using mode_config.mutex for internals
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Those are now all protected using fb_helper->lock.

v2: We still need to hold mode_config.mutex right around calling
connector->fill_modes.

v3: I forgot to hold mode_config.mutex while looking at
connector->status and the mode list. Also, we need to patch up the
i915 ->initial_config callback to grab the locks it needs to inspect
the modeset state recovered from the fw.

v4: Don't reorder the probe too much (Ville).

Subject: drm/fb-helper: Split dpms handling into legacy and atomic paths

Like with panning and modesetting, and like with those, stick with
simple drm_modeset_locking_all for the legacy path, and the full
atomic dance for atomic drivers.

This means a bit more boilerplate since setting up the atomic state
machinery is rather verbose, but then this is shared code for 30+
drivers or so, so meh.

After this patch there's only the LUT/cmap path which is still using
drm_modeset_lock_all for an atomic driver. But Peter is already
locking into reworking that, so I'll leave that code as-is for now.

v2: Squash in patches from Maarten to unify all the various atomic
paths into just one atomic update function for fbdev overall. On top
do one s/restore_fbdev_mode/restore_fbdev_mode_atomic/ so that we have
all-atomic callchains after the first check.

Subject: drm/fb-helper: keep the .gamma_store updated in drm_fb_helper_setcmap

I think the gamma_store can end up invalid on error. But the way I read
it, that can happen in drm_mode_gamma_set_ioctl as well, so why should
this pesky legacy fbdev stuff be any better?

Subject: drm/fb-helper: remove drm_fb_helper_save_lut_atomic

drm_fb_helper_save_lut_atomic is redundant since the .gamma_store is
now always kept up to date by drm_fb_helper_setcmap.

Subject: drm: i915: sysfs: constify attribute_group structures.

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.

Subject: drm/i915: Setting pch_id for HSW/BDW in virtual environment

In a IGD passthrough environment, the real ISA bridge may doesn't exist.
then pch_id couldn't be correctly gotten from ISA bridge, but pch_id is
used to identify LPT_H and LPT_LP. Currently i915 treat all LPT pch as
LPT_H,then errors occur when i915 runs on LPT_LP machines with igd
passthrough.

This patch set pch_id for HSW/BDW according to IGD type and isn't fully
correct. But it solves such issue on HSW/BDW ult/ulx machines.
QA CI system is blocked by this issue for a long time, it's better that
we could merge it to unblock QA CI system.

We know the root cause is in device model of virtual passthrough, and
will resolve it in the future with several parts cooperation in kernel,
qemu and xen.

 i915_gem_context_create

We need to reap the stale contexts for all new contexts, be they created
by user in i915_gem_context_ioctl or from opening a new file in
i915_gem_context_open. Both paths may be called very frequently
accumulating many stale contexts before any worker has a chance to run
and free their memory.

Subject: drm/i915: Drop request retirement before reaping stale contexts

Before we create a new context, we try and reap all the stale contexts
(i.e. those that are freed but waiting for a worker to come and return
their allocations to the system). Before we do this, we retire all
requests so that we clear any inflight no longer used contexts (who are
only being kept alived by those inflght requests). However, any context
that is finally unreferenced by this retirement is put onto an RCU list
and not available for immediately reaping, we stall for no immediate
benefit.

Subject: drm/i915: Only free the oldest stale context before allocating

Currently, we move all unreferenced contexts to an RCU free list and
then onto a worker for eventual reaping. To compensate against this
growing into a long list with frequent allocations starving the system
of available memory, before we allocate a new context we reap all the
stale contexts. This puts all the cost of destroying the context into
the next allocator, which is presumably more sensitive to syscall
latency and unfair. We can limit the number of contexts being freed by
the new allocator to both keep the list trimmed and to allow the
allocator to be reasonably fast.

Subject: drm/i915/bxt, glk: Fix assert on conditions for DC9 enabling

What we want to assert based on the conditions required by Bspec is that
power well 2 is disabled, so no need to check for other power wells.
In addition we can only check if the driver's request is removed, the
actual state depends on whether the other request bits are set or not
(BIOS, KVMR, DEBUG). So check only the driver's request bit.

Subject: drm/i915/gen9+: Don't remove secondary power well requests

So far in an attempt to make sure all power wells get disabled during
display uninitialization the driver removed any secondary request bits
(BIOS, KVMR, DEBUG) that were set for a given power well. The known
source for these requests was DMC's request on power well 1 and the misc
IO power well. Since DMC is inactive (DC states are disabled) at the
point we disable these power wells, there shouldn't be any reason to
leave them on. However there are two problems with the above
assumption: Bspec requires that the misc IO power well stays enabled
(without providing a reason) and there can be KVMR requests that we
can't remove anyway (the KVMR request register is R/O). Atm, a KVMR
request can trigger a timeout WARN when trying to disable power wells.

To make the code aligned to Bspec and to get rid of the KVMR WARN, don't
try to remove the secondary requests, only detect them and stop polling
for the power well disabled state when any one is set.

Also add a comment about the timeout values required by Bspec when
enabling power wells and the fact that waiting for them to get disabled
is not required by Bspec.

Subject: iio: accel: st_accel: add SPI-3wire support

Add SPI Serial Interface Mode (SIM) register information
in st_sensor_settings look up table to support devices
(like LSM303AGR accel sensor) that allow just SPI-3wire
communication mode. SIM mode has to be configured before any
other operation since it is not enabled by default and the driver
is not able to read without that configuration

Whilst a fairly substantial patch, the actual logic is simple and it
is better to have the generic fix than a band aid.

In order to select the alternate voltage reference pair (VALTH/VALTL), the
right value for the REFSEL field in the ADCx_CFG register is "01", leading
to 0x800 as register mask. See section 8.2.6.4 in the reference manual[1].

Subject: drm/i915/cnl: Add force wake for gen10+.

By spec there is no change on force wake registers
for Cannonlake. Let's reuse gen9 one.

v2: Adding missing case for the write part. (Tvrtko)
v3: Rebase on recent tree.
v4: Make it for gen9+ instead adding gen10 only. (by Joonas).

Subject: drm/i915/cnl: Don't trust VBT's alternate pin for port D for now.

Cannon Lake's VBT that is currently available for B0 stepping
states that port D uses alternate pin 3 messing up with the
default pin-port mapping table. Using that information we cannot
get HDMI working properly. So for now we don't relly on VBT for
this information.

Subject: drm/i915/cnl: Get DDI clock based on PLLs.

PLLs are the source clocks for the DDIs so in order
to determine the ddi clock we need to check the PLL
configuration.

v2: Mika pointed out that 24 was hardcoded while it
    should consider ref clock that can be either 24KHz
    or 19.2KHz on CNL.

Subject: staging: iio: tsl2x7x: add of_match table for device tree support

Add device tree support for the tsl2x7x IIO driver with no custom
properties. The device tree documentation is in a separate commit so
that the changes to trivial-devices.txt can go in via the device
tree subsystem.

The TSL2X7X driver has a custom power_state sysfs attribute. Remove this
attribute since the runtime power management code provides a sysfs
attribute to control the power state of the device.

tsl2x7x_i2c_read() would call i2c_smbus_write_byte() and
i2c_smbus_read_byte(). These two i2c functions can be replaced with a
single call to i2c_smbus_read_byte_data(). This patch removes the

i2c_smbus_read_byte_data().

Subject: staging: iio: tsl2x7x: cleaned up i2c calls in
 tsl2x7x_als_calibrate()

The calibration function calls i2c_smbus_write_byte() and
i2c_smbus_read_byte(). These two function calls are replaced with a
single call to i2c_smbus_read_byte_data() by this patch. This patch
also removes an unnecessary call that reads the CNTRL register
a second time. One of the error paths returned -1 if the ADC was not
enabled and this patch changes that return value to -EINVAL.

Subject: staging: iio: tsl2x7x: refactor {read,write}_event_value to allow
 handling multiple iio_event_infos

tsl2x7x_read_thresh() and tsl2x7x_write_thresh() currently assumes
that IIO_EV_INFO_VALUE is the only iio_event_info that will be
passed in.  This patch refactors these two functions so that
additional iio_event_infos can be passed in. The functions are
renamed from tsl2x7x_{read,write}_thresh() to
tsl2x7x_{read,write}_event_value(). This patch also adds the
missing return value check to tsl2x7x_invoke_change() since this
was previously missing. This patch is in preparation for moving
the in_intensity0_thresh_period and in_proximity0_thresh_period sysfs
attributes to be created by iio_event_spec.

Subject: staging: iio: tsl2x7x: use usleep_range() instead of mdelay()

This driver in some cases can busy wait for upwards of 15ms. Since the
kernel at this point is not running in atomic context, and is running in
process context, we can safely use usleep_range() instead. This patch
changes the two occurrences of mdelay() to usleep_range().

Subject: staging: iio: tsl2x7x: check return value from
 tsl2x7x_invoke_change()

The return value from tsl2x7x_invoke_change() was not checked in most
places in the driver. This patch adds the proper error checks. The
return values inside tsl2x7x_invoke_change() are now checked by
this patch as well.

Previously, if there was an error turning the chip back on, then the
driver would attempt to turn the chip off and incorrectly return
success. The code to power off the chip is removed by this patch
since we should fail fast.

Subject: iio: adc: axp288: Fix the GPADC pin reading often wrongly returning 0

I noticed in its DSDT that one of my tablets actually is using the GPADC
pin for temperature monitoring.

The whole axp288_adc_set_ts() function is a bit weird, in the past it was
removed because it seems to make no sense, then this was reverted because
of regressions.

So I decided to test the special GPADC pin handling on this tablet.
Conclusion: not only is axp288_adc_set_ts() necessary, we need to sleep a
bit after making the AXP288_ADC_TS_PIN_CTRL changes before sampling the
GPADC, otherwise it will often (about 80% of the time) read 0 instead of
its actual value.

It seems that there is only 1 bias current source and to be able to use it
for the GPIO0 pin in GPADC mode it must be temporarily turned off for the
TS pin, but the datasheet does not mention this.

This commit adds a sleep after disabling the TS pin bias current,
fixing the GPADC more often then not wrongly returning 0.

Subject: drm: inhibit drm drivers register to uninitialized drm core

If the DRM core fails to init for whatever reason, ensure that
no driver ever calls drm_dev_register().

This is best done at drm_dev_init() as it covers drivers that call
drm_dev_alloc() as well as drivers that prefer to embed struct
drm_device into their own device struct and call drm_dev_init()
themselves.

In my case I had so many dynamic device majors used that the major
number for DRM (226) was stolen, causing DRM core init to fail after
failing to register a chrdev, and ultimately calling debugfs_remove()
on drm_debugfs_root in drm_core_exit().

After drm core failed to init, VGEM was still calling drm_dev_register(),
ultimately leading to drm_debugfs_init(), with drm_debugfs_root passed
as the root for the new debugfs dir at debugfs_create_dir().

This led to a kernel panic once we were either derefencing root->d_inode
while it was NULL or calling root->d_inode->i_op->lookup() while it was
NULL in debugfs at inode_lock() or lookup_*().

Subject: drm/i915/cnl: Add missing type case.

Paulo had noticed that inside cnl_ddi_vswing_program
the case was handling voltage but with no indication
of type where a missing type could also take us to that
path. So my first attempt was to add a message to
let clear who trigger that path.

However DK had a better idea that is to handle the
missed type sooner before it might take to that path.
So this v2 here uses his approach.

v2: Handle missed type sooner.

Subject: drm/simple-kms-helper: Fix the check for the mismatch between plane
 and CRTC enabled.

You can enable the CRTC and without adding the plane to the state and
it will succeed. This should be prevented in the crtc check instead of
the plane check, because the plane check may never run for atomic
enable, but the crtc check always will.

This is based on a similar check in vmwgfx.

to be removed.

Subject: drm/i915: Always perform internal fixed16 division in 64 bits

This patch combines fixed_16_16_div & fixed_16_16_div_u64 wrappers.
And new fixed_16_16_div wrapper always performs division operation in
u64 internally, to avoid any data loss which was happening in earlier
version of wrapper.
earlier wrapper was converting u32 to fixed16 in 32 bit so we were
losing 16-MSB data.

Subject: drm/i915: Addition wrapper for fixed16.16 operation

This patch introduce addition wrapper for fixed point 16.16 operations.
Which will be used by later patches to avoid direct member variables
access of fixed_16_16_t structure.

add_fixed16 : takes 2 fixed_16_16_t variable & returns fixed_16_16_t
add_fixed16_u32 : takes fixed_16_16_t & u32 variable & returns fixed_16_16_t

Subject: drm/atomic: Make private objs proper objects
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make the atomic private object stuff less special by introducing proper
base classes for the object and its state. Drivers can embed these in
their own appropriate objects, after which these things will work
exactly like the plane/crtc/connector states during atomic operations.

v2: Reorder to not depend on drm_dynarray (Daniel)

Subject: drm/i915/fbdev: Always forward hotplug events

With deferred fbdev setup we always need to forward hotplug events,
even if fbdev isn't fully set up yet. Otherwise the deferred setup
will neer happen.

Originally this check was added in

commit c45eb4fed12d278d3619f1904885bd0d7bcbf036 (tag: drm-intel-next-fixes-2016-08-05)

    drm/i915/fbdev: Check for the framebuffer before use

But the specific case of the hotplug function blowing up was fixed in

We could probably hit this already with our current async fbdev init,
but it's much easier to hit this with the new deferred fbdev setup
that I'm working on polishing.

Subject: drm: rename, adjust and export drm_atomic_replace_property_blob

The function has little to do with atomic, it's just where it has so
far been needed. So, rename it to drm_property_replace_blob, move it
to drm_property.c and export it.

Change the semantics to return whether the blob was replaced instead
of using an extra argument for that.

This has a couple of benefits:
- it makes the redundant fb helpers .load_lut, .gamma_set and .gamma_get
  completely obsolete. They are now unused and subject for removal.
- atomic drivers that support clut modes get fbdev support for those from
  the drm core. This includes atmel-hlcdc, but perhaps others as well?

Subject: drm/amdgpu: disable vga render in dce hw_init

This got dropped accidently with the fb location changes, but for
some reason, this doesn't seem to cause an issue on all cards which
is why I never saw it despite extensive testing.  I suspect it may
only be an issue on systems with a legacy sbios that enables vga.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes mc programming much simpler in future patches.

Since evergreen, the vbios has been programming the fb location
to the proper vram size.  The only reason to reprogram it would
be to change the location.

From e4f6b39e8bcd1f4c455acbc1aef2de9a4a32deeb Mon Sep 17 00:00:00 2001
From: Alex Deucher <alexander.deucher@amd.com>

Subject: drm/amdgpu: remove *_mc_access from display funcs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These are no longer needed now that we use the fb_location
programmed by the vbios.

Subject: drm/radeon: Allow vblank_disable_immediate.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With instantaneous high precision vblank timestamping
that updates at leading edge of vblank, a cooked hw
vblank counter which increments at leading edge of
vblank, and reliable page flip execution and completion
at leading edge of vblank, we should meet the requirements
for fast/immediate vblank irq disable/enable.

Testing on Linux-4.12-rc5 + drm-next on a Radeon HD 5770
(DCE 4) with timing measurement equipment indicates this
works fine, so allow immediate vblank disable for power
saving.

For debugging in case of unexpected trouble, booting
with kernel cmdline option drm.vblankoffdelay=0
(or echo 0 > /sys/module/drm/parameters/vblankoffdelay)
would keep vblank irqs permanently on to approximate old
behavior.

Subject: drm/amdgpu: Support passing amdgpu critical error to host via GPU
 Mailbox.

This feature works for SRIOV enviroment. For non-SRIOV enviroment, the
trans_error function does nothing.

The error information includes error_code (16bit), error_flags(16bit)
and error_data(64bit). Since there are not many errors, we keep the
errors in an array and transfer all errors to Host before amdgpu
initialization function (amdgpu_device_init) exit.

Subject: drm/amdgpu: Changed CU reservation golden settings

With previous golden settings, compute task can't use
reserved LDS (32K) on CU0 and CU1. On 64K LDS system,
if compute work group allocate more than 32K LDS, then
it can't be dispatched to CU0 and CU1 because of the
reservation. This enables compute task to use reserved
LDS on CU0 and CU1.

Subject: drm/amdgpu:fix world switch hang
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

for SR-IOV, we must keep the pipeline-sync in the protection
of COND_EXEC, otherwise the command consumed by CPG is not
consistent when world switch triggerd, e.g.:

world switch hit and the IB frame is skipped so the fence
won't signal, thus CP will jump to the next DMAframe's pipeline-sync
command, and it will make CP hang foever.

after pipelin-sync moved into COND_EXEC the consistency can be
guaranteed

Subject: drm/amdgpu: set firmware loading type as direct by default for raven

In previous case, driver can't enable psp via the kernel parameter for raven.
We should open this path and set it as direct by default till psp firmware
loading is workable.

The arrays pctl0_data and pctl1_data do not need to be in global scope,
so them both static.

Cleans up sparse warnings:
symbol 'pctl0_data' was not declared. Should it be static?
symbol 'pctl1_data' was not declared. Should it be static?

Subject: drm/amdgpu: Add vis_vramlimit module parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allow specifying a limit on visible VRAM via a module parameter. This is
helpful for testing performance under visible VRAM pressure.

v2: Add cast to 64-bit (Christian König)

Subject: drm/amdgpu: Throttle visible VRAM moves separately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The BO move throttling code is designed to allow VRAM to fill quickly if it
is relatively empty. However, this does not take into account situations
where the visible VRAM is smaller than total VRAM, and total VRAM may not
be close to full but the visible VRAM segment is under pressure. In such
situations, visible VRAM would experience unrestricted swapping and
performance would drop.

Add a separate counter specifically for moves involving visible VRAM, and
check it before moving BOs there.

v2: Only perform calculations for separate counter if visible VRAM is
    smaller than total VRAM. (Michel Dänzer)
v3: [Michel Dänzer]
* Use BO's location rather than the AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED
  flag to determine whether to account a move for visible VRAM in most
  cases.
* Use a single

	if (adev->mc.visible_vram_size < adev->mc.real_vram_size) {

  block in amdgpu_cs_get_threshold_for_moves.

Subject: drm/amdgpu: Set/clear CPU_ACCESS flag on page fault and move to VRAM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a BO is moved to VRAM, clear AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED.
This allows it to potentially later move to invisible VRAM if the CPU
does not access it again.

Setting the CPU_ACCESS flag in amdgpu_bo_fault_reserve_notify() also means
that we can remove the loop to restrict lpfn to the end of visible VRAM,
because amdgpu_ttm_placement_init() will do it for us.

v3 [Michel Dänzer]
* Use AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED instead of a new flag
  (Christian König)
* Clear flag in amdgpu_bo_move instead of amdgpu_move_ram_vram
  (Christian)
* Explicitly mention amdgpu_bo_fault_reserve_notify in amdgpu_bo_move
* Also clear flag in amdgpu_bo_create_restricted

Subject: drm/amdgpu: Don't force BOs into visible VRAM for page faults
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There is no need for page faults to force BOs into visible VRAM if it's
full, and the time it takes to do so is great enough to cause noticeable
stuttering. Add GTT as a possible placement so that if visible VRAM is
full, page faults move BOs to GTT instead of evicting other BOs from VRAM.

Subject: drm/amdgpu: Try evicting from CPU visible to invisible VRAM first
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This gives BOs which haven't been accessed by the CPU since they were
moved to visible VRAM another chance to stay in VRAM when another BO
needs to go to visible VRAM.

This should allow BOs to stay in VRAM longer in some cases.

v2:
* Only do this for BOs which don't have the
  AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED flag set.

For GFX context, the  ATC bit in SDMA*_GFX_VIRTUAL_ADDRESS  can be cleared
to perform in VM mode. For RLC context, to support ATC mode , ATC bit in
SDMA*_RLC*_VIRTUAL_ADDRESS should be set. SDMA_CNTL.ATC_L1_ENABLE bit is
global setting that enables the  L1-L2 translation for ATC address.

Subject: drm/amdgpu: Send no-retry XNACK for all fault types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A subset of VM fault types currently send retry XNACK to the client.
This causes a storm of interrupts from the VM to the host.

Until the storm is throttled by other means send no-retry XNACK for
all fault types instead. No change in behavior to the client which
will stall indefinitely with the current configuration in any case.
Improves system stability under GC or MMHUB faults.

This is just future proofing code, not something that can be triggered
in real life.  We're testing to make sure we don't shift wrap when we
do "1ull << i" so "i" has to be in the 0-63 range.  If it's 64 then we
have gone too far.

We need to wait with the correct owner on unmap operations or otherwise can run
into VM faults.

Also always wait for the page directory since this is where the reservation
object comes from. So rename the function to amdgpu_vm_wait_pd instead as well.

Also reorder includes into the common order.

Subject: drm/tinydrm: Add RePaper e-ink driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This adds support for the Pervasive Displays RePaper branded displays.
The controller code is taken from the userspace driver available
through repaper.org. Only the V231 film is supported since the others
are EOL.

Subject: drm: handle HDMI 2.0 VICs in AVI info-frames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).

This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.

This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.

In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
	- VIC for 4K modes for HDMI 1.4 sinks
	- S3D information for S3D modes
  As CEA-861-F has already defined VICs for 4K videomodes, this
  patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
  until the mode is 3D.

V2: Rebase, Added r-b from Andrzej
V3: Addressed review comment from Ville:
	- Do not send VICs in both AVI-IF and HDMI-IF
	  send only one of it.
V4: Rebase
V5: Added r-b from Neil.
    Addressed review comments from Ville
    - Do not block HDMI vendor IF, instead check for VIC while
      handling AVI infoframes

Subject: drm/edid: complete CEA modedb(VIC 1-107)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CEA-861-F specs defines new video modes to be used with
HDMI 2.0 EDIDs. The VIC range has been extended from 1-64 to
1-107.

Our existing CEA modedb contains only 64 modes (VIC=1 to VIC=64). Now
to be able to parse new CEA modes using the existing methods, we have
to complete the modedb (VIC=65 onwards).

This patch adds:
- Timings for existing CEA video modes (from VIC=65 till VIC=92)
- Newly added 4k modes (from VIC=93 to VIC=107).

The patch was originaly discussed and reviewed here:
https://patchwork.freedesktop.org/patch/135810/

    Remove unnecessary paranthesis from function svd_to_vic (Ville)
    Added r-b (Neil)
V6: Rebase
V7: Fix indentation for modes from VIC 80

Subject: drm/edid: parse sink information before CEA blocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CEA-861-F adds ycbcr capability map block, for HDMI 2.0 sinks.
This block contains a map of indexes of CEA modes, which can
support YCBCR 420 output also. To avoid multiple parsing of same
CEA block, let's parse the sink information and get this map, before
parsing CEA modes.

This patch moves the call to drm_add_display_info function, before the
mode parsing block.

V4: Introduced new patch in the series
V5: Move this patch before 4:2:0 parsing patch (ville)

Subject: drm/edid: cleanup patch for CEA extended-tag macro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CEA-861-F introduces extended tag codes for EDID extension blocks,
which indicates the actual type of the data block. The code for
using exteded tag is 0x7, whereas in the existing code, the
corresponding macro is named as "VIDEO_CAPABILITY_BLOCK"

This patch renames the macro and usages from "VIDEO_CAPABILITY_BLOCK"
to "USE_EXTENDED_TAG"

V2: Add extended tag code check for video capabilitiy block (ville)

Subject: drm: add helper to validate YCBCR420 modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

YCBCR420 modes are supported only on HDMI 2.0 capable sources.
This patch adds:
- A drm helper to validate YCBCR420-only mode on a particular
  connector. This function will help pruning the YCBCR420-only
  modes from the connector's modelist.
- A bool variable (ycbcr_420_allowed) in the drm connector structure.
  While handling the EDID from HDMI 2.0 sinks, its important to know
  if the source is capable of handling YCBCR420 output, so that no
  YCBCR 420 modes will be listed for sources which can't handle it.
  A driver should set this variable if it wants to see YCBCR420 modes
  in the modedb.

V5: Introduced the patch in series.
V6: Squashed two patches (validate YCBCR420 and add YCBCR420
	   identifier)
V7: Addressed review comments from Vile:
    - Move this patch before we add 420 modes from EDID.
    - No need for drm_valid_cea_vic() check, function back to non-static.
    - Update MODE_STATUS with NO_420 condition.
    - Introduce y420_vdb_modes variable in this patch

Subject: drm/edid: parse YCBCR420 videomodes from EDID
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HDMI 2.0 spec adds support for YCBCR420 sub-sampled output.
CEA-861-F adds two new blocks in EDID's CEA extension blocks,
to provide information about sink's YCBCR420 output capabilities.

These blocks are:

- YCBCR420vdb(YCBCR 420 video data block):
This block contains VICs of video modes, which can be sopported only
in YCBCR420 output mode (Not in RGB/YCBCR444/422. Its like a normal
SVD block, valid for YCBCR420 modes only.

- YCBCR420cmdb(YCBCR 420 capability map data block):
This block gives information about video modes which can support
YCBCR420 output mode also (along with RGB,YCBCR444/422 etc) This
block contains a bitmap index of normal svd videomodes, which can
support YCBCR420 output too.
So if bit 0 from first vcb byte is set, first video mode in the svd
list can support YCBCR420 output too. Bit 1 means second video mode
from svd list can support YCBCR420 output too, and so on.

This patch adds two bitmaps in display's hdmi_info structure, one each
for VCB and VDB modes. If the source is HDMI 2.0 capable, this patch
adds:
- VDB modes (YCBCR 420 only modes) in connector's mode list, also makes
  an entry in the vdb_bitmap per vic.
- VCB modes (YCBCR 420 also modes) only entry in the vcb_bitmap.

V2: Addressed
    Review comments from Emil:
    - Use 1ULL<<i instead of 1<<i to make sure the output is 64bit.
    - Use the suggested method for updating dbmap.
    - Add documentation for YCBCR420_vcb_map to fix kbuild warning.

    Review comments from Ville:
    - Do not expose the YCBCR420 flags in uabi layer, keep it internal.
    - Save a map of YCBCR420 modes for future reference.
    - Check db length before trying to parse extended tag.
    - Add a warning if there are > 64 modes in capability map block.
    - Use y420cmdb in function names and macros while dealing with vcb
      to be aligned with spec.
    - Move the display information parsing block ahead of mode parsing
      blocks.

V3: Addressed design/review comments from Ville
    - Do not add flags in video modes, else we have to expose them to user
    - There should not be a UABI change, and kernel should detect the
      choice of the output based on type of mode, and the bitmaps.
    - Use standard bitops from kernel bitmap header, instead of calculating
      bit positions manually.

V4: Addressed review comments from Ville:
    - s/ycbcr_420_vdb/y420vdb
    - s/ycbcr_420_vcb/y420cmdb
    - Be less verbose on description of do_y420vdb_modes
    - Move newmode variable in the loop scope.
    - Use svd_to_vic() to get a VIC, instead of 0x7f
    - Remove bitmap description for CMDB modes & VDB modes
    - Dont add connector->ycbcr_420_allowed check for cmdb modes
    - Remove 'len' variable, in is_y420cmdb function, which is used
      only once
    - Add length check in is_y420vdb function
    - Remove unnecessary if (!db) check in function parse_y420cmdb_bitmap
    - Do not add print about YCBCR 420 modes
    - Fix indentation in few places
    - Move ycbcr420_dc_modes in next patch, where its used
    - Add a separate patch for movement of drm_add_display_info()

V5: Addressed review comments from Ville:
    - Add the patch which cleans up the current EXTENDED_TAG usage
    - Make y420_cmdb_map u64
    - Do not block ycbcr420 modes while parsing the EDID, rather
      add a separate helper function to prune ycbcr420-only modes from
      connector's probed modes.

V6: Rebase
V7: Move this patch after the 420_only validation patch (Ville)
V8: Addressed review comments from Ville
    - use cea_vic_valid check before adding cmdb/vdb modes
    - add check for i < 64 while adding cmdb modes
    - use 1ULL while checking bitmap

Subject: drm: add helper functions for YCBCR420 handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds helper functions for YCBCR 420 handling.
These functions do:
- check if a given video mode is YCBCR 420 only mode.
- check if a given video mode is YCBCR 420 also mode.

V2: Added YCBCR functions as helpers in DRM layer, instead of
    keeping it in I915 layer.
V3: Added handling for YCBCR-420 only modes too.
V4: EXPORT_SYMBOL(drm_find_hdmi_output_type)
V5: Addressed review comments from Danvet:
    - %s/drm_find_hdmi_output_type/drm_display_info_hdmi_output_type
    - %s/drm_can_support_ycbcr_output/drm_display_supports_ycbcr_output
    - %s/drm_can_support_this_ycbcr_output/
		drm_display_supports_this_ycbcr_output
    - pass drm_display_info instead of drm_connector for consistency
    - For drm_get_highest_quality_ycbcr_supported doc, move the variable
      description above, and then the function description.
V6: Add only YCBCR420 helpers (Ville)
V7: Addressed review comments from Ville
    - Remove cea_vic_valid() check.
    - Fix indentation.
    - Make input parameters to helpers, const.

Subject: drm/vc4: Fix DSI T_INIT timing.

The DPHY spec requires a much larger T_INIT than I was specifying
before.  In the absence of clear specs from the slave of what their
timing is, just use the value that the firmware was using.

gcc-7 points out an older regression:

drivers/staging/iio/resolver/ad2s1210.c: In function 'ad2s1210_read_raw':
drivers/staging/iio/resolver/ad2s1210.c:515:42: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]

The original code had 'unsigned short' here, but incorrectly got
converted to 'bool'. This reverts the regression and uses a normal
type instead.

When adding maps to the list, they were added using list_add, which adds
them in LIFO order. When parsing using iio_channel_get_all(), these
elements are hence returned in reverse order. As a result, the iio_hwmon
mapping maps the first entry to the last channel and so on.

Subject: cpufreq: speedstep: remove unnecessary static in
 speedstep_detect_chipset()

Remove unnecessary static on local variable hostbridge.
Such variable is initialized before being used,
on every execution path throughout the function.
The static has no benefit and, removing it reduces
the code size.

This issue was detected using Coccinelle and the following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the code size. Also,
there is a significant difference in the bss segment. This log is the
output of the size command, before and after the code change:

Subject: PM / OPP: OF: Use pr_debug() instead of pr_err() while adding OPP
 table

Some platforms add the OPPs dynamically from platform specific drivers
instead of getting them statically from DT. The cpufreq-dt driver
already ignores the return value of dev_pm_opp_of_cpumask_add_table() to
not error out for such cases, but we still end up printing error message
from that routine. That's not nice.

Convert the print message to use pr_debug() instead.

Subject: staging: ccree: Use __func__ instead of function name

Fixed following checkpatch.pl warning:
	WARNING: Prefer using '"%s...", __func__' to using
the function's name, in a string

It is prefered to use '%s & __func__' instead of function
name for logging.

Subject: staging: ccree: remove unnecessary cast on kmalloc

The assignment operator implicitly converts a void pointer to the type of the
pointer it is assigned to.

This issue was detected using Coccinelle and the following semantic patch:

@@
expression * e;
expression arg1, arg2;
type T;
@@

- e=(T*)

Subject: staging: ccree: move FIPS support to kernel infrastructure

The ccree driver had its own FIPS support, complete with
a test harness comparable to crypto testmgr and an
implementation which disables crypto functionality on
FIPS test error detection, either in Linux or from TEE.

This patch removes the duplication, while reimplementing
the handling of TEE reported FIPS errors according to the
kernel policy of inducing a panic in such an event.

Subject: staging: wilc1000: Neaten refresh_scan - remove always 1 argument

All uses of refresh_scan() have a constant 1 as the second argument.
Remove it and neaten the function declaration.

Miscellanea:

o Remove overly deep indentation by using continue;
o Remove unnecessary test of the address of a static array as it's
  always non-zero
o Rename and use proper type for the first void * argument as it's
  always the struct wilc_priv *
o Move variables into loop where used

Subject: staging: typec: Fix endianness warning discovered by sparse

The below warning is resolved by removing the cpu_to_le32() call. This
call was redundant; vdm_run_state_machine() ensures that SVDM responses
have the correct endianness before sending.

typec/tcpm.c:1019:49: warning: incorrect type in assignment (different base types)
typec/tcpm.c:1019:49:    expected unsigned int [unsigned] [usertype] <noident>
typec/tcpm.c:1019:49:    got restricted __le32 [usertype] <noident>

Subject: staging: lustre: lnet: remove dead code and useless wrapper

After removing commented out code, ksocknal_csum() becomes a useless
wrapper for crc32_le(). Remove it, and instead call crc32_le() directly.

Fixes the following checkpatch warning:

WARNING: space prohibited before semicolon

Subject: staging: ccree: clean up struct ssi_aead_ctx

struct ssi_aead_ctx has some nested structure defined, resulting
in code accessing them to be very unreadable.

Move out the nested structure definitions out of the struct
and use the change to make the code accessing it more readable
and better coding style compliant by shortening lines and
properly matching alignment,

Subject: staging: rtl8192u: reduce stack frame size in ieee80211_rx_mgt_rsl

I ran into a stack frame size warning in code that hasn't changed much
recently, no idea why I didn't spot this earlier despite build many
thousand randconfigs.

drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c: In function 'ieee80211_rx_mgt_rsl':
drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c:2563:1: error: the frame size of 1676 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

We have a couple of other copies of the same function in the kernel,
and they simply don't put a gigantic structure on the stack, so I'm
changing this copy to do the same as the others, replacing the
stack variable with a GFP_ATOMIC allocation.

Subject: fs/locks: Remove fl_nspid and use fs-specific l_pid for remote locks

Since commit c69899a17ca4 "NFSv4: Update of VFS byte range lock must be
atomic with the stateid update", NFSv4 has been inserting locks in rpciod
worker context.  The result is that the file_lock's fl_nspid is the
kworker's pid instead of the original userspace pid.

The fl_nspid is only used to represent the namespaced virtual pid number
when displaying locks or returning from F_GETLK.  There's no reason to set
it for every inserted lock, since we can usually just look it up from
fl_pid.  So, instead of looking up and holding struct pid for every lock,
let's just look up the virtual pid number from fl_pid when it is needed.
That means we can remove fl_nspid entirely.

The translaton and presentation of fl_pid should handle the following four
cases:

1 - F_GETLK on a remote file with a remote lock:
    In this case, the filesystem should determine the l_pid to return here.
    Filesystems should indicate that the fl_pid represents a non-local pid
    value that should not be translated by returning an fl_pid <= 0.

2 - F_GETLK on a local file with a remote lock:
    This should be the l_pid of the lock manager process, and translated.

3 - F_GETLK on a remote file with a local lock, and
4 - F_GETLK on a local file with a local lock:
    These should be the translated l_pid of the local locking process.

Fuse was already doing the correct thing by translating the pid into the
caller's namespace.  With this change we must update fuse to translate
to init's pid namespace, so that the locks API can then translate from
init's pid namespace into the pid namespace of the caller.

With this change, the locks API will expect that if a filesystem returns
a remote pid as opposed to a local pid for F_GETLK, that remote pid will
be <= 0.  This signifies that the pid is remote, and the locks API will
forego translating that pid into the pid namespace of the local calling
process.

Finally, we convert remote filesystems to present remote pids using
negative numbers. Have lustre, 9p, ceph, cifs, and dlm negate the remote
pid returned for F_GETLK lock requests.

Since local pids will never be larger than PID_MAX_LIMIT (which is
currently defined as <= 4 million), but pid_t is an unsigned int, we
should have plenty of room to represent remote pids with negative
numbers if we assume that remote pid numbers are similarly limited.

If this is not the case, then we run the risk of having a remote pid
returned for which there is also a corresponding local pid.  This is a
problem we have now, but this patch should reduce the chances of that
occurring, while also returning those remote pid numbers, for whatever
that may be worth.

+For Raspbian users only
+=======================
+Since Raspbian supports device tree overlays, you may use and overlay, instead
+of editing your boards device tree.
+For using the overlay, you need to compile the file pi433-overlay.dts you can
+find aside to this documentation.
+The file needs to be compiled - either manually or by integration in your kernel
+source tree. For a manual compile, you may use a command line like the following:
+'linux/scripts/dtc/dtc -@ -I dts -O dtb -o pi433.dtbo pi433-overlay.dts'
+
+For compiling inside of the kernel tree, you need to copy pi433-overlay.dts to
+arch/arm/boot/dts/overlays and you need to add the file to the list of files
+in the Makefile over there. Execute 'make dtbs' in kernel tree root to make the
+kernel make files compile the device tree overlay for you.

+
+Introduction
+============
+This driver is for controlling pi433, a radio module for the Raspberry Pi
+(www.pi433.de). It supports transmission and reception. It can be opened
+by multiple applications for transmission and reception. While transmit
+jobs were queued and process automatically in the background, the first
+application asking for reception will block out all other applications
+until something gets received terminates the read request.
+The driver supports on the fly reloading of the hardware fifo of the rf
+chip, thus enabling for much longer telegrams then hardware fifo size.
+
+Discription of driver operation
+===============================
+
+a) transmission
+
+Each transmission can take place with a different configuration of the rf
+module. Therfore each application can set its own set of parameters. The driver
+takes care, that each transmission takes place with the parameterset of the
+application, that requests the transmission. To allow the transmission to take
+place in the background, a tx thread is introduced.
+The transfer of data from the main thread to the tx thread is realised by a
+kfifo. With each write request of an application, the passed in data and the
+corresponding parameter set gets written to the kfifo.
+On the other "side" of the kfifo, the tx thread continuously checks, whether the
+kfifo is empty. If not, it gets one set of config and data from the kfifo. If
+there is no receive request or the receiver is still waiting for something in
+the air, the rf module is set to standby, the parameters for transmission gets
+set, the hardware fifo of the rf chip gets preloaded and the transmission gets
+started. Upon hardware fifo threshold interrupt it gets reloaded, thus enabling
+much longer telegrams then hardware fifo size. If the telegram is send and there
+is more data available in the kfifo, the procedure is repeated. If not the
+transmission cycle ends.
+
+b) reception
+
+Since there is only one application allowed to receive data at a time, for
+reception there is only one configuration set.
+As soon as an application sets an request for receiving a telegram, the reception
+configuration set is written to the rf module and it gets set into receiving mode.
+Now the driver is waiting, that a predefined RSSI level (signal strength at the
+receiver) is reached. Until this hasn't happened, the reception can be
+interrupted by the transmission thread at any time to insert a transmission cycle.
+As soon as the predefined RSSI level is meat, a receiving cycle starts. Similar
+as described for the transmission cycle the read out of the hardware fifo is done
+dynamically. Upon each hardware fifo threshold interrupt, a portion of data gets
+read. So also for reception it is possible to receive more data then the hardware
+fifo can hold.
+
+
+Driver API
+==========
+
+The driver is currently implemented as a character device. Therefore it supports
+the calls open, ioctl, read, write and close.
+
+
+params for ioctl
+----------------
+
+There are four options:
+PI433_IOC_RD_TX_CFG - get the transmission parameters from the driver
+PI433_IOC_WR_TX_CFG - set the transmission parameters
+PI433_IOC_RD_RX_CFG - get the receiving parameters from the driver
+PI433_IOC_WR_RX_CFG - set the receiving parameters
+
+The tx configuration is transfered via struct pi433_tx_cfg, the parameterset for transmission.
+It is devided into two sections: rf parameters and packet format.
+
+rf params:
+	frequency
+		frequency used for transmission.
+		Allowed values: 433050000...434790000
+	bit_rate
+		bit rate used for transmission.
+		Allowed values: #####
+	dev_frequency
+		frequency deviation in case of FSK.
+		Allowed values: 600...500000
+	modulation
+		FSK - frequency shift key
+		OOK - On-Off-key
+	modShaping
+		shapingOff	- no shaping
+		shaping1_0	- gauss filter with BT 1 (FSK only)
+		shaping0_5	- gauss filter with BT 0.5 (FSK only)
+		shaping0_3	- gauss filter with BT 0.3 (FSK only)
+		shapingBR	- filter cut off at BR (OOK only)
+		shaping2BR	- filter cut off at 2*BR (OOK only)

+		ramp40		- amp ramps up in 40us
+		ramp31		- amp ramps up in 31us
+		ramp25		- amp ramps up in 25us
+		ramp20		- amp ramps up in 20us
+		ramp15		- amp ramps up in 15us
+		ramp12		- amp ramps up in 12us

+	tx_start_condition
+		fifoLevel	- transmission starts, if fifo is filled to
+				  threshold level
+		fifoNotEmpty	- transmission starts, as soon as there is one
+				  byte in internal fifo
+	repetitions
+		This gives the option, to send a telegram multiple times. Default: 1
+
+packet format:
+	enable_preamble
+		optionOn	- a preamble will be automatically generated
+		optionOff	- no preamble will be generated
+	enable_sync
+		optionOn	- a sync word will be automatically added to
+				  the telegram after preamble
+		optionOff	- no sync word will be added
+		Attention: While possible to generate sync without preamble, the
+		receiver won't be able to detect the sync without preamble.
+	enable_length_byte
+		optionOn	- the length of the telegram will be automatically
+				  added to the telegram. It's part of the payload
+		optionOff	- no length information will be automatically added
+				  to the telegram.

+		Attention: should be used in combination with sync, only
+	enable_address_byte
+		optionOn	- the address byte will be automatically added to the
+				  telgram. It's part of the payload
+		optionOff	- the address byte will not be added to the telegram.
+		The address byte can be used for address filtering, so the receiver
+		will only receive telegrams with a given address byte.
+		Attention: should be used in combination with sync, only
+	enable_crc
+		optionOn	- an crc will be automatically calculated over the
+				  payload of the telegram and added to the telegram
+				  after payload.

+	sync_length
+		length of the sync word. Allowed values: 0...8
+	fixed_message_length

+		given by the buffer, passed in with the write command. Will be
+		ignored if set to zero.
+	sync_pattern[8]
+		contains up to eight values, that are used as the sync pattern
+		on sync option
+	address_byte
+		one byte, used as address byte on address byte option.
+
+
+The rx configuration is transfered via struct pi433_rx_cfg, the parameterset for receiving. It is devided into two sections: rf parameters and packet format.
+
+rf params:
+	frequency
+		frequency used for transmission.
+		Allowed values: 433050000...434790000
+	bit_rate
+		bit rate used for transmission.
+		Allowed values: #####

+		Allowed values: 600...500000
+	modulation
+		FSK - frequency shift key
+		OOK - on off key
+	rssi_threshold
+		threshold value for the signal strength on the receiver input.
+		If this value is exeeded, a reception cycle starts
+		Allowed values: 0...255
+	thresholdDecrement
+		in order to adapt to different levels of singnal strength, over
+		time the receiver gets more and more sensitive. This value
+		determs, how fast the sensitivity increases.
+		step_0_5db	- increase in 0,5dB steps
+		step_1_0db	- increase in 1 db steps
+		step_1_5db	- increase in 1,5dB steps

+		Allowd values: 0...7
+	dagc;
+		operation mode of the digital automatic gain control
+		normalMode
+		improve
+		improve4LowModulationIndex
+
+ packet format:
+	enable_sync
+		optionOn  - sync detection is enabled. If configured sync pattern
+			    isn't found, telegram will be internally discarded
+		optionOff - sync detection is disabled.
+	enable_length_byte
+		optionOn   - First byte of payload will be used as length byte,
+			     regardless of the amount of bytes that were requested
+			     by the read request.
+		optionOff  - Number of bytes to be read will be set according to

+					  node, nor the broadcast address will
+					  be internally discarded
+		Attention: Sync option must be enabled in order to use this feature
+	enable_crc
+		optionOn	- a crc will be calculated over the payload of
+				  the telegram, that was received. If the
+				  calculated crc doesn't match to two bytes,
+				  that follow the payload, the telegram will be
+				  internally discarded.
+		Attention: This option is only operational, if sync on and fixed length
+		or length byte is used
+	sync_length
+		Gives the length of the payload.
+		Attention: This setting must meet the setting of the transmitter,
+		if sync option is used.
+	fixed_message_length
+		Overrides the telegram length either given by the first byte of
+		payload or by the read request.
+	bytes_to_drop
+		gives the number of bytes, that will be dropped before transfering
+		data to the read buffer
+		This option is only usefull, if all packet helper are switched
+		off and the rf chip is used in raw receiving mode. This may be
+		needed, if a telegram of a third party device should be received,
+		using a protocol not compatible with the packet engine of the rf69 chip.
+	sync_pattern[8]
+		contains up to eight values, that are used as the sync pattern
+		on sync option.
+		This setting must meet the configuration of the transmitting device,
+		if sync option is enabled.
+	node_address
+		one byte, used as node address byte on address byte option.
+	broadcast_address
+		one byte, used as broadcast address byte on address byte option.

Subject: sunvnet: add support for IPv6 checksum offloads

The original code didn't handle non-IPv4 packets very well, so the
offload advertising had to be scaled back down to just IP.  Here we
add the bits needed to support TCP and UDP packets over IPv6 and
turn the offload advertising back on.

Subject: EDAC, mce_amd: Use cpu_to_node() to find the node ID

Using the homegrown amd_get_nb_id() to find a node ID on AMD was fine
while the L3 to node mapping was 1:1. And Zen topology broke this. So
let's start slowly moving away from it and use the topology interfaces
instead.

Subject: drm/sun4i: constify drm_plane_helper_funcs

drm_plane_helper_funcs are not supposed to change at runtime.
All functions working with drm_plane_helper_funcs provided by
<drm/drm_plane_helper.h> work with const drm_plane_helper_funcs.
So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
    981	     40	      0	   1021	    3fd drivers/gpu/drm/sun4i/sun4i_layer.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   1021	      0	      0	   1021	    3fd drivers/gpu/drm/sun4i/sun4i_layer.o

Subject: drm/sun4i: hdmi: Implement I2C adapter for A10s DDC bus

The documentation for drm_do_get_edid in drivers/gpu/drm/drm_edid.c states:
"As in the general case the DDC bus is accessible by the kernel at the I2C
level, drivers must make all reasonable efforts to expose it as an I2C
adapter and use drm_get_edid() instead of abusing this function."

Exposing the DDC bus as an I2C adapter is more beneficial as it can be used
for purposes other than reading the EDID such as modifying the EDID or
using the HDMI DDC pins as an I2C bus through the I2C dev interface from
userspace (e.g. i2c-tools).

Implement this for A10s.

Subject: drm/sun4i: Implement drm_driver lastclose to restore fbdev console

The drm_driver lastclose callback is called when the last userspace
DRM client has closed. Call drm_fbdev_cma_restore_mode to restore
the fbdev console otherwise the fbdev console will stop working.

Fixes: 9026e0d122ac ("drm: Add Allwinner A10 Display Engine support")

Subject: VFS: Convert sb->s_flags & MS_RDONLY to sb_rdonly(sb)

Firstly by applying the following with coccinelle's spatch:

	@@ expression SB; @@
	-SB->s_flags & MS_RDONLY
	+sb_rdonly(SB)

to effect the conversion to sb_rdonly(sb), then by applying:

	@@ expression A, SB; @@
	(
	-(!sb_rdonly(SB)) && A
	+!sb_rdonly(SB) && A
	|
	-A != (sb_rdonly(SB))
	+A != sb_rdonly(SB)
	|
	-A == (sb_rdonly(SB))
	+A == sb_rdonly(SB)
	|
	-!(sb_rdonly(SB))
	+!sb_rdonly(SB)
	|
	-A && (sb_rdonly(SB))
	+A && sb_rdonly(SB)
	|
	-A || (sb_rdonly(SB))
	+A || sb_rdonly(SB)
	|
	-(sb_rdonly(SB)) != A
	+sb_rdonly(SB) != A
	|
	-(sb_rdonly(SB)) == A
	+sb_rdonly(SB) == A
	|
	-(sb_rdonly(SB)) && A
	+sb_rdonly(SB) && A
	|
	-(sb_rdonly(SB)) || A
	+sb_rdonly(SB) || A
	)

	@@ expression A, B, SB; @@
	(
	-(sb_rdonly(SB)) ? 1 : 0
	+sb_rdonly(SB)
	|
	-(sb_rdonly(SB)) ? A : B
	+sb_rdonly(SB) ? A : B
	)

to remove left over excess bracketage and finally by applying:

	@@ expression A, SB; @@
	(
	-(A & MS_RDONLY) != sb_rdonly(SB)
	+(bool)(A & MS_RDONLY) != sb_rdonly(SB)
	|
	-(A & MS_RDONLY) == sb_rdonly(SB)
	+(bool)(A & MS_RDONLY) == sb_rdonly(SB)
	)

to make comparisons against the result of sb_rdonly() (which is a bool)
work correctly.

Subject: EDAC: Constify attribute_group structures

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.

Subject: pinctrl: sh-pfc: r8a7795: Fix MSIOF3_{SS1,SS2}_E pin function
 definitions

This patch fixes the incorrect IPSR register value definitions for
MSIOF3_{SS1,SS2}_E pin functions.

This is a correction to the incorrect implementation of IPSR register pin
assignment of the specifications updated for R8A7795 ES2.0 SoC in R-Car
Gen3 Hardware User's Manual Rev.0.53E.

Fixes: b205914c8f822ef2 ("pinctrl: sh-pfc: r8a7795: Add support for R-Car H3 ES2.0")

Subject: pinctrl: sh-pfc: r8a7796: Fix MSIOF3_{SS1,SS2}_E pin function
 definitions

This patch fixes the incorrect IPSR register value definitions for
MSIOF3_{SS1,SS2}_E pin functions.

This is a correction to the incorrect implementation of IPSR register
pin assignment for R8A7796 SoC specification of R-Car Gen3 Hardware
User's Manual Rev.0.51E or later.

Subject: pinctrl: sh-pfc: r8a7796: Fix MOD_SEL register pin assignment for
 TCLK{1,2}_{A,B} pins group

This patch fixes to set MOD_SEL2 bit19 when using TCLK2_A pin function is
selected for IPSR16 bit[23:20] or using TCLK2_B pin function is selected
for IPSR17 bit[27:24].

This is a correction to the incorrect implementation of MOD_SEL register
pin assignment for R8A7796 SoC specification of R-Car Gen3 Hardware

Subject: pinctrl: sh-pfc: r8a7796: Rename CS1# pin function definitions

This patch renames the pin function macro definitions of the GPSR1 and
IPSR4 registers value for the CS1# pin.

This is a correction because GPSR and IPSR register specification for
R8A7796 SoC was changed in R-Car Gen3 Hardware User's Manual Rev.0.54E.

Subject: extcon: cros-ec: Add extcon-cros-ec driver to support display out

This is the driver for the USB Type C cable detection mechanism
built into the ChromeOS Embedded Controller on systems that
have USB Type-C ports.

At present, this allows for the presence of display out, but in
future, it may also be used to notify host and device type cables
and the presence of power.

Subject: drm/imx: lock scanout transfers for consecutive bursts

Because of its shallow queues and limited reordering ability, the i.MX6Q
memory controller likes AXI bursts of consecutive addresses a lot.
To optimize memory access performance, lock the IPU scanout channels for
a number of burst accesses each, before switching to the next channel.
The burst size and length of a locked burst chain are chosen not to
overshoot the stride.

Enabling the 8-burst channel lock on a single 1920x1080@60Hz RGBx
scanout (474 MiB/s of 64-byte IPU memory read accesses) reduces the
reported memory controller busy cycles from 46% to below 28% on an
otherwise idle i.MX6Q.

Subject: spi: imx: introduce fifo_size and has_dmamode in spi_imx_devtype_data

Different ECSPI controller has different fifosize and DMA capability,
instead of calling functions to identify these information by check
devtype. add fifo_size and has_dmamode to spi_imx_devtype_data.
so that these information can be directly accessed.

Subject: spi: pxa2xx: Only claim CS GPIOs when the slave device is created

Avoid hogging chip select GPIOs just because they are listed for the
master. They might be mulitplexed and, if no slave device is attached,
used for different purposes. Moreover, this strategy avoids having to
allocate a cs_gpiods structure.

Tested on the IOT2000 where the second SPI bus is connected to an
Arduino-compatible connector and multiplexed between SPI, GPIO and PWM
usage.

Subject: spi: sh-msiof: Limit minimum divider on R-Car Gen3

On R-Car Gen3 SoCs (excluding R-Car H3 ES1.x, which cannot be used for
SPI due to a hardware erratum), BRPS x BRDV = 1/1 is an invalid divider
setting.
Implement this limitation using an SoC/family-specific minimum divider.

The original patch from Tony uses standby mode bit inverted, which is
not correct. This fixes all instances in the driver code for get & set
mode. This did not yet make problems, since mode has not been changed
by any mainline driver so far.

Subject: drm/i915: Fix error checking/locking in perf/lookup_context()

1acfc104cdf8 missed to convert this one caller to be lockless. The side
effect of that was that the error check in lookup_context() became
incorrect. Convert now this caller too.

Subject: backlight: lm3630a: Bump REG_MAX value to 0x50 instead of 0x1F

In the lm3630a_chip_init we try to write to 0x50 register, which is
higher value then the max_register value, this resulted in regmap_write
return -EIO.

Fix this by bumping REG_MAX value to 0x50.

This code was introduced with the chip revision in commit 28e64a68a2ef,
however setting filter strength was failing silently because it used
unsigned int for storing and comparing the return values. Bug related to
signedness was fixed in 2a0c316bf3cc, which made it error out correctly
instead of failing silently.

I found this issue by using this driver on LGE Nexus 5 (hammerhead).
After this commit lm3630a_chip_init succeeds instead of failing with
-EIO.

Fixes: 28e64a68a2ef ("backlight: lm3630: apply chip revision")
Fixes: 2a0c316bf3cc ("drivers/video/backlight/lm3630a_bl.c: fix
signedness bug in lm3630a_chip_init()")

Subject: staging: lustre: lustre: fix all braces issues reported by checkpatch

Cleanup all braces that was reported by checkpatch. The only
issue not fixed up is in mdc_lock.c. Removing the braces in
the case of mdc_lock.c will break the build.

Continuation of splitting the binder allocator from the binder
driver. Separate binder_alloc functions from normal binder
functions. Protect the allocator with a separate mutex.

From 0c972a05cde66e3d448419c120627083d6419f8f Mon Sep 17 00:00:00 2001
From: Todd Kjos <tkjos@android.com>
Date: Thu, 29 Jun 2017 12:01:41 -0700
Subject: binder: move binder_alloc to separate file

Move the binder allocator functionality to its own file

Continuation of splitting the binder allocator from the binder
driver. Split binder_alloc functions from normal binder functions.

Add kernel doc comments to functions declared extern in
binder_alloc.h

Subject: binder: remove binder_debug_no_lock mechanism

With the global lock, there was a mechanism to access
binder driver debugging information with the global
lock disabled to debug deadlocks or other issues.
This mechanism is rarely (if ever) used anymore
and wasn't needed during the development of
fine-grained locking in the binder driver.
Removing it.

Subject: binder: add log information for binder transaction failures

Add additional information to determine the cause of binder
failures. Adds the following to failed transaction log and
kernel messages:
	return_error : value returned for transaction
	return_error_param : errno returned by binder allocator
	return_error_line : line number where error detected

Also, return BR_DEAD_REPLY if an allocation error indicates
a dead proc (-ESRCH)

Subject: binder: refactor queue management in binder_thread_read

In binder_thread_read, the BINDER_WORK_NODE command is used
to communicate the references on the node to userspace. It
can take a couple of iterations in the loop to construct
the list of commands for user space. When locking is added,
the lock would need to be release on each iteration which
means the state could change. The work item is not dequeued
during this process which prevents a simpler queue management
that can just dequeue up front and handle the work item.

Fixed by changing the BINDER_WORK_NODE algorithm in
binder_thread_read to determine which commands to send
to userspace atomically in 1 pass so it stays consistent
with the kernel view.

The work item is now dequeued immediately since only
1 pass is needed.

Subject: binder: avoid race conditions when enqueuing txn

Currently, the transaction complete work item is queued
after the transaction. This means that it is possible
for the transaction to be handled and a reply to be
enqueued in the current thread before the transaction
complete is enqueued, which violates the protocol
with userspace who may not expect the transaction
complete. Fixed by always enqueing the transaction
complete first.

Also, once the transaction is enqueued, it is unsafe
to access since it might be freed. Currently,
t->flags is accessed to determine whether a sync
wake is needed. Changed to access tr->flags
instead.

Subject: binder: don't modify thread->looper from other threads

The looper member of struct binder_thread is a bitmask
of control bits. All of the existing bits are modified
by the affected thread except for BINDER_LOOPER_STATE_NEED_RETURN
which can be modified in binder_deferred_flush() by
another thread.

To avoid adding a spinlock around all read-mod-writes to
modify a bit, the BINDER_LOOPER_STATE_NEED_RETURN flag
is replaced by a separate field in struct binder_thread.

Subject: binder: protect against two threads freeing buffer

Adds protection against malicious user code freeing
the same buffer at the same time which could cause
a crash. Cannot happen under normal use.

Subject: binder: use atomic for transaction_log index

The log->next index for the transaction log was
not protected when incremented. This led to a
case where log->next++ resulted in an index
larger than ARRAY_SIZE(log->entry) and eventually
a bad access to memory.

Fixed by making the log index an atomic64 and
converting to an array by using "% ARRAY_SIZE(log->entry)"

Also added "complete" field to the log entry which is
written last to tell the print code whether the
entry is complete

Subject: binder: refactor binder_pop_transaction

binder_pop_transaction needs to be split into 2 pieces to
to allow the proc lock to be held on entry to dequeue the
transaction stack, but no lock when kfree'ing the transaction.

Split into binder_pop_transaction_locked and binder_free_transaction
(the actual locks are still to be added).

Subject: binder: guarantee txn complete / errors delivered in-order

Since errors are tracked in the return_error/return_error2
fields of the binder_thread object and BR_TRANSACTION_COMPLETEs
can be tracked either in those fields or via the thread todo
work list, it is possible for errors to be reported ahead
of the associated txn complete.

Use the thread todo work list for errors to guarantee
order. Also changed binder_send_failed_reply to pop
the transaction even if it failed to send a reply.

Subject: binder: make sure target_node has strong ref

When initiating a transaction, the target_node must
have a strong ref on it. Then we take a second
strong ref to make sure the node survives until the
transaction is complete.

Subject: binder: make sure accesses to proc/thread are safe

binder_thread and binder_proc may be accessed by other
threads when processing transaction. Therefore they
must be prevented from being freed while a transaction
is in progress that references them.

This is done by introducing a temporary reference
counter for threads and procs that indicates that the
object is in use and must not be freed. binder_thread_dec_tmpref()
and binder_proc_dec_tmpref() are used to decrement
the temporary reference.

It is safe to free a binder_thread if there
is no reference and it has been released
(indicated by thread->is_dead).

It is safe to free a binder_proc if it has no
remaining threads and no reference.

A spinlock is added to the binder_transaction
to safely access and set references for t->from
and for debug code to safely access t->to_thread
and t->to_proc.

From 372e3147df7016ebeaa372939e8774a1292db558 Mon Sep 17 00:00:00 2001
From: Todd Kjos <tkjos@android.com>
Date: Thu, 29 Jun 2017 12:01:58 -0700
Subject: binder: refactor binder ref inc/dec for thread safety

Once locks are added, binder_ref's will only be accessed
safely with the proc lock held. Refactor the inc/dec paths
to make them atomic with the binder_get_ref* paths and
node inc/dec. For example, instead of:

  ref = binder_get_ref(proc, handle, strong);
  ...
  binder_dec_ref(ref, strong);

we now have:

  ret = binder_dec_ref_for_handle(proc, handle, strong, &rdata);

Since the actual ref is no longer exposed to callers, a
new struct binder_ref_data is introduced which can be used
to return a copy of ref state.

From adc1884222276df6eb018f78bccacbcd78a0b9f6 Mon Sep 17 00:00:00 2001
From: Todd Kjos <tkjos@android.com>
Date: Thu, 29 Jun 2017 12:01:59 -0700
Subject: binder: use node->tmp_refs to ensure node safety

When obtaining a node via binder_get_node(),
binder_get_node_from_ref() or binder_new_node(),
increment node->tmp_refs to take a
temporary reference on the node to ensure the node
persists while being used.  binder_put_node() must
be called to remove the temporary reference.

Subject: binder: introduce locking helper functions

There are 3 main spinlocks which must be acquired in this
order:
1) proc->outer_lock : protects most fields of binder_proc,
	binder_thread, and binder_ref structures. binder_proc_lock()
	and binder_proc_unlock() are used to acq/rel.
2) node->lock : protects most fields of binder_node.
	binder_node_lock() and binder_node_unlock() are
	used to acq/rel
3) proc->inner_lock : protects the thread and node lists
	(proc->threads, proc->nodes) and all todo lists associated
	with the binder_proc (proc->todo, thread->todo,
	proc->delivered_death and node->async_todo).
	binder_inner_proc_lock() and binder_inner_proc_unlock()
	are used to acq/rel

Any lock under procA must never be nested under any lock at the same
level or below on procB.

Functions that require a lock held on entry indicate which lock
in the suffix of the function name:

foo_olocked() : requires node->outer_lock
foo_nlocked() : requires node->lock
foo_ilocked() : requires proc->inner_lock
foo_iolocked(): requires proc->outer_lock and proc->inner_lock
foo_nilocked(): requires node->lock and proc->inner_lock

Subject: binder: use inner lock to sync work dq and node counts

For correct behavior we need to hold the inner lock when
dequeuing and processing node work in binder_thread_read.
We now hold the inner lock when we enter the switch statement
and release it after processing anything that might be
affected by other threads.

We also need to hold the inner lock to protect the node
weak/strong ref tracking fields as long as node->proc
is non-NULL (if it is NULL then we are guaranteed that
we don't have any node work queued).

This means that other functions that manipulate these fields
must hold the inner lock. Refactored these functions to use
the inner lock.

From 72196393a5e3d28c21679e3b745c06dd4a5b24c9 Mon Sep 17 00:00:00 2001
From: Todd Kjos <tkjos@android.com>

Subject: binder: add spinlocks to protect todo lists

The todo lists in the proc, thread, and node structures
are accessed by other procs/threads to place work
items on the queue.

The todo lists are protected by the new proc->inner_lock.
No locks should ever be nested under these locks. As the
name suggests, an outer lock will be introduced in
a later patch.

From 673068eee8560d57e0b37bbb52157811b7f5b563 Mon Sep 17 00:00:00 2001
From: Todd Kjos <tkjos@android.com>
Date: Thu, 29 Jun 2017 12:02:03 -0700
Subject: binder: add spinlock to protect binder_node

node->node_lock is used to protect elements of node. No
need to acquire for fields that are invariant: debug_id,
ptr, cookie.

From da0fa9e4e8c5aac7cafa6cbb14d908ab8bbffd2f Mon Sep 17 00:00:00 2001
From: Todd Kjos <tkjos@android.com>
Date: Thu, 29 Jun 2017 12:02:04 -0700
Subject: binder: protect proc->nodes with inner lock

When locks for binder_ref handling are added, proc->nodes
will need to be modified while holding the outer lock

Subject: binder: protect proc->threads with inner_lock

proc->threads will need to be accessed with higher
locks of other processes held so use proc->inner_lock
to protect it. proc->tmp_ref now needs to be protected
by proc->inner_lock.

Subject: binder: protect transaction_stack with inner lock.

This makes future changes to priority inheritance
easier, since we want to be able to look at a thread's
transaction stack when selecting a thread to inherit
priority for.

It also allows us to take just a single lock in a
few paths, where we used to take two in succession.

Subject: binder: protect binder_ref with outer lock

Use proc->outer_lock to protect the binder_ref structure.
The outer lock allows functions operating on the binder_ref
to do nested acquires of node and inner locks as necessary
to attach refs to nodes atomically.

Binder refs must never be accesssed without holding the
outer lock.

Subject: binder: protect against stale pointers in print_binder_transaction

When printing transactions there were several race conditions
that could cause a stale pointer to be deferenced. Fixed by
reading the pointer once and using it if valid (which is
safe). The transaction buffer also needed protection via proc
lock, so it is only printed if we are holding the correct lock.

Subject: binder: fix death race conditions

A race existed where one thread could register
a death notification for a node, while another
thread was cleaning up that node and sending
out death notifications for its references,
causing simultaneous access to ref->death
because different locks were held.

Subject: mei: me: enable asynchronous probing

On some platforms, currently Broxton, Apollo Lake and Kaby Lake,
ME FW may be busy with internal bookkeeping and answering late
to the start message.
As a mitigation, the driver requests for a synchronous probing
to prevent stalling of the overall boot process. For example,
on a Apollo Lake platform the overall boot time has reduced from
~0.9 to ~0.6 seconds on average.

Subject: mei: me: use an index instead of a pointer for private data

Device 'new_id' interface is useful for testing of not yet published
hardware on older kernels and for internally used device ids on
simulation platforms.
However currently with the device configuration held in device_id driver
data as a pointer to mei_cfg structure it is hard, as one need to locate
the address of the correct structure.
A recommended way of doing that is to use and index instead of a
pointer.
This patch adds a new list of configuration mei_cfg_list[]
indexed via enum mei_cfg_idx.
In addition it cleanups ich platform naming, renames legacy
generation to ich and what was ich to ich10.

Subject: spi: loopback-test: provide loop_req option.

Provide a module parameter to request internal loop by the SPI master
controller.
This should make loop testing easier without extra HW modification.

For test automation a logic analyzer is recommended for host
controller-independent verification.
An example test rig configuration and procedure:
  i.MX6S RIoRBoard           Logic Analyzer
  -----------------------------------------
  (J13  4) GND ------------- GND
  (J13  6) CSPI3-CLK ------> PIN 3
  (J13  8) CSPI3-MOSI <----- PIN 2
     ^ - internal loop configured by SPI_LOOP
     |   or can be user external jamper.
  (J13 10) CSPI3-MISO -----> PIN 1

grab some data and decode it:
sigrok-cli -d fx2lafw --time 160000 --config samplerate=10m  \
  --channels 0-2 -o dump.sr
sigrok-cli -i dump.sr -P spi:mosi=1:clk=2 > result_for_regression_tests

Subject: drm/crc: Handle opening and closing crc better

When I was doing a grep . -r /sys/kernel/debug/dri/0 I noticed a WARN
appearing when I aborted the grep with ^C.

After investigating I've also noticed that the error handling was
lacking and there are race conditions involving multiple calls to
open/close simultaneously.

Fix this by setting the opened flag first and using crc->entries to
decide when crc can be collected.

Also call unset crc source before cleaning up, this way there is
no race with a future open().

This patch has been tested with all the tests in igt with CRC in their
name.

Subject: drm/crc: Only open CRC on atomic drivers when the CRTC is active.

Commit e8fa5671183c ("drm: crc: Wait for a frame before returning
from open()") adds a wait for CRC frame, but with the CRTC off
this will never be generated. For atomic drivers we know if a CRTC
is active through crtc_state->active, so when inactive reject the
open with -EIO.

Just like with the previous patch changing debugfs opening semantics,
this patch has been tested against igt.

Subject: vmbus: more host signalling avoidance

Don't signal host if it has disabled interrupts for that
ring buffer. Check the feature bit to see if host supports
pending send size flag.

Subject: char/mwave: make some arrays static const to make object code smaller

Don't populate arrays on the stack but make them static.  Makes
the object code smaller.  Also remove temporary variables that
have hard coded array sizes and just use ARRAY_SIZE instead and
wrap some lines that are wider than 80 chars to clean up some
checkpatch warnings.

Subject: fpga manager: Add altera-ps-spi driver for Altera FPGAs

altera-ps-spi loads FPGA firmware over SPI, using the "passive serial"
interface on Altera Arria 10, Cyclone V or Stratix V FPGAs.

This is one of the simpler ways to set up an FPGA at runtime.
The signal interface is close to unidirectional SPI with lsb first.

Subject: arch_topology: Convert switch block to if block

We only need to take care of one case here (CPUFREQ_NOTIFY) and there is
no need to add an extra level of indentation to the case specific code
by using a switch block. Use an if block instead.

Also add some blank lines to make the code look better.

Subject: arch_topology: Localize cap_parsing_failed to
 topology_parse_cpu_capacity()

cap_parsing_failed is only required in topology_parse_cpu_capacity() to
know if we have already tried to allocate raw_capacity and failed, or if
at least one of the cpu_node didn't had the required
"capacity-dmips-mhz" property.

All other users can use raw_capacity instead of cap_parsing_failed.

Make sure we set raw_capacity to NULL after we free it.

Subject: arch_topology: Get rid of cap_parsing_done

There is no need to check for cap_parsing_done flag anymore as
!raw_capacity flag alone is enough for us. Remove the (now) useless flag
cap_parsing_done.

+XILINX AXI ETHERNET Device Tree Bindings
+--------------------------------------------------------
+
+Also called  AXI 1G/2.5G Ethernet Subsystem, the xilinx axi ethernet IP core
+provides connectivity to an external ethernet PHY supporting different
+interfaces: MII, GMII, RGMII, SGMII, 1000BaseX. It also includes two
+segments of memory for buffering TX and RX, as well as the capability of
+offloading TX/RX checksum calculation off the processor.
+
+Management configuration is done through the AXI interface, while payload is
+sent and received through means of an AXI DMA controller. This driver
+includes the DMA driver code, so this driver is incompatible with AXI DMA
+driver.
+
+For more details about mdio please refer phy.txt file in the same directory.
+
+Required properties:
+- compatible	: Must be one of "xlnx,axi-ethernet-1.00.a",
+		  "xlnx,axi-ethernet-1.01.a", "xlnx,axi-ethernet-2.01.a"
+- reg		: Address and length of the IO space.
+- interrupts	: Should be a list of two interrupt, TX and RX.
+- phy-handle	: Should point to the external phy device.
+		  See ethernet.txt file in the same directory.
+- xlnx,rxmem	: Set to allocated memory buffer for Rx/Tx in the hardware
+
+Optional properties:
+- phy-mode	: See ethernet.txt
+- xlnx,phy-type	: Deprecated, do not use, but still accepted in preference
+		  to phy-mode.
+- xlnx,txcsum	: 0 or empty for disabling TX checksum offload,
+		  1 to enable partial TX checksum offload,
+		  2 to enable full TX checksum offload
+- xlnx,rxcsum	: Same values as xlnx,txcsum but for RX checksum offload
+
+Example:
+	axi_ethernet_eth: ethernet@40c00000 {
+		compatible = "xlnx,axi-ethernet-1.00.a";
+		device_type = "network";
+		interrupt-parent = <&microblaze_0_axi_intc>;
+		interrupts = <2 0>;
+		phy-mode = "mii";
+		reg = <0x40c00000 0x40000>;
+		xlnx,rxcsum = <0x2>;
+		xlnx,rxmem = <0x800>;
+		xlnx,txcsum = <0x2>;
+		phy-handle = <&phy0>;
+		axi_ethernetlite_0_mdio: mdio {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			phy0: phy@0 {
+				device_type = "ethernet-phy";
+				reg = <1>;
+			};
+		};

Subject: mlxsw: spectrum: Mark packets trapped in router

In commit 1c6c6d221e2b ("mlxsw: spectrum: Mirror certain packets to
CPU") we marked packets that were mirrored to the CPU, so that they
won't be flooded again by the bridge driver.

However, certain packets are trapped in the device's router block, after
passing through the bridge block where they were potentially flooded.

Mark all packets coming from L3 traps, so that they won't be potentially
flooded again by the bridge driver.

In case local sockets have the IP_ROUTER_ALERT socket option set, then
they expect to get packets with the Router Alert option.

Trap such packets, so that the kernel could inspect them and potentially
send them to interested sockets.

Subject: mlxsw: spectrum: Improve IPv6 unregistered multicast flooding

Up until now IPv6 unregistered multicast traffic would be flooded like
broadcast, even when MLD snooping was enabled on the bridge. This was
intentional as MLD packet traps were missing, preventing the bridge
driver from programming MDB entries to the device.

Previous patch added these traps, so we can now finally flood IPv6
unregistered multicast packets to specific ports via the multicast table
instead of flooding them to all ports via the broadcast table.

Subject: ixgbe: add initial support for xdp redirect

There are optimizations we can add after the basic feature is
enabled. But, for now keep the patch simple.

Subject: xdp: Add batching support to redirect map

For performance reasons we want to avoid updating the tail pointer in
the driver tx ring as much as possible. To accomplish this we add
batching support to the redirect path in XDP.

This adds another ndo op "xdp_flush" that is used to inform the driver
that it should bump the tail pointer on the TX ring.

Subject: ntb: use correct mw_count function in ntb_tool and ntb_transport

After converting to the new API, both ntb_tool and ntb_transport are
using ntb_mw_count to iterate through ntb_peer_get_addr when they
should be using ntb_peer_mw_count.

This probably isn't an issue with the Intel and AMD drivers but
this will matter for any future driver with asymetric memory window
counts.

Subject: clk: axs10x: introduce AXS10X pll driver

AXS10X boards manages it's clocks using various PLLs. These PLL has same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.

Each PLL on AXS10X board consist of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.

We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.

As of today we add support for PLLs that generate clock for the
following devices:
 * ARC core on AXC CPU tiles.
 * ARC PGU on ARC SDP Mainboard.
and more to come later.

By this patch we add support for two plls (arc core pll and pgu pll),
so we had to use two different init types: CLK_OF_DECLARE for arc core pll and
regular probing for pgu pll.

+Binding for the AXS10X Generic PLL clock
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible: should be "snps,axs10x-<name>-pll-clock"
+  "snps,axs10x-arc-pll-clock"
+  "snps,axs10x-pgu-pll-clock"
+- reg: should always contain 2 pairs address - length: first for PLL config
+registers and second for corresponding LOCK CGU register.
+- clocks: shall be the input parent clock phandle for the PLL.
+- #clock-cells: from common clock binding; Should always be set to 0.
+
+Example:
+	input-clk: input-clk {
+		clock-frequency = <33333333>;
+		compatible = "fixed-clock";
+		#clock-cells = <0>;
+	};
+
+	core-clk: core-clk@80 {

Subject: clk: vc5: Prevent division by zero on unconfigured outputs

In case the initial values of the FOD registers are not configured in
the OTP or by the bootloader, it is possible that the FOD registers
will contain zeroes. The code in vc5_fod_recalc_rate() immediately
feeds the FOD divider value obtained from the FOD registers into the
div64_u64() and if the FOD divider value is zero, triggers division
by zero exception.

Check if the FOD divider value is zero and return the frequency of
the FOD output as 0 Hz if it is so. This prevents the division by
zero exception.

Subject: clk: vc5: Do not warn about disabled output buffer input muxes

The output buffer input mux can be configured in either of three
states -- disabled, input from FOD, input from previous output.
If the output buffer input mux is set to disabled, the code in
vc5_clk_out_get_parent() would consider this an invalid setting
and warn about it, which is not necessarily the case.

In case the output buffer input mux is disabled, default to input
from FOD to have some parent and don't print the warning.

Subject: clk: vc5: Configure the output buffer input mux on prepare

The output buffer input mux can be configured in either of three
states -- disabled, input from FOD, input from previous output.
Once the .prepare() callback of the output buffer is called, the
output buffer input mux must be set to either input from FOD or
input from previous output, it cannot be set to Disabled anymore
or the output won't work.

Default to the input from FOD if the output buffer input mux was
Disabled and the .prepare() was called on it.

Note that we do not set the output buffer input mux back to Disabled
in the .unprepare() callback as there is no obvious benefit of doing
so. We disable the entire output buffer in the .unprepare() callback
already.

Subject: clk: vc5: Split clock input mux and predivider

Split the VC5 clock input mux and the predivider to more accurately
model the hardware and fix the previously incorrect assumption that
both the OUT_SEL_I2CB and the PLL are fed from the predivider.

It is in fact the clock input mux output which is directly feeding
the clock into the OUT_SEL_I2CB output, while the clock input mux
output first passes through the predivider before it is fed into
the PLL.

Update IDT VersaClock 5 driver to support 5P49V5925. This chip has only
external clock input, four fractional dividers (FODs) and five clock
outputs (four universal clock outputs and one reference clock output at
OUT0_SELB_I2C).

Subject: iio: accel: bmc150: Always restore device to normal mode after
 suspend-resume

After probe we would put the device in normal mode, after a runtime
suspend-resume we would put it back in normal mode. But for a regular
suspend-resume we would only put it back in normal mode if triggers
or events have been requested.  This is not consistent and breaks
reading raw values after a suspend-resume.

This commit changes the regular resume path to also unconditionally put
the device back in normal mode, fixing reading of raw values not working
after a regular suspend-resume cycle.

Subject: clk: qcom: clk-smd-rpm: Fix the reported rate of branches

As there is no way to actually query the hardware for the current clock
rate, now racalc_rate() just returns the last rate that was previously
set. But if the rate was not set yet, we return the bogus rate of 1000Hz.

The branch clocks have the same rate as their parent, so in this case we
just need to remove recalc_rate ops and then the core framework will handle
this automagically. The round_rate() is unused, so remove it as well.

Subject: clk: moxart: remove unnecessary statics

Remove unnecessary static on local variable _base_ in both functions
moxart_of_pll_clk_init() and moxart_of_apb_clk_init(). Such variables
are initialized before being used, on every execution path throughout
the mentioned functions. The statics have no benefit and, removing
them reduce the code size.

This issue was detected using Coccinelle and the following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the code size. Also,
notice that the bss segment is reduced down to zero. This log is the
output of the size command, before and after the code change:

Subject: clk: mmp: Drop unnecessary static

Drop static on a local variable, when the variable is initialized before
any possible use.  Thus, the static has no benefit.

The semantic patch that fixes this problem is as follows:

Subject: drm/stm: ltdc: Fix leak of px clk enable in some error paths

The pixel clock gets enabled early during init, since it's required
in order to read registers. This pixel clock must be disabled if
errors during this init phase.

From a21960339c8c107eae99d68c85e6355189b22192 Mon Sep 17 00:00:00 2001
From: Matthias Kaehlcke <mka@chromium.org>
Date: Mon, 17 Jul 2017 11:14:03 -0700
Subject: drm/i915: Consistently use enum pipe for PCH transcoders

The current code uses in some instances enum transcoder for PCH
transcoders and enum pipe in others. This is error prone and clang
raises warnings like this:

drivers/gpu/drm/i915/intel_dp.c:3546:51: warning: implicit conversion
  from enumeration type 'enum pipe' to different enumeration type
  'enum transcoder' [-Wenum-conversion]
    intel_set_pch_fifo_underrun_reporting(dev_priv, PIPE_A, false);

Consistently use the type enum pipe for PCH transcoders.

Subject: staging: unisys: visorbus: Fix memory leak

The name of a visor_device was never freed, which was allocated in
visorbus_configure.

It is expected that visorbus_device_destroy will not be called on the
same visor_device again, or this would be a double free.

Subject: drm: Don't complain too much about struct_mutex.

For modern drivers the DRM core doesn't use struct_mutex at all, which
means it's defacto a driver-private lock. But since we still need it
for legacy drivers we can't initialize it in drivers, which means all
the different instances share one lockdep key. Despite that they might
be placed in totally different places in the locking hierarchy.

This results in a lot of bogus lockdep splats when running stuff on
systems with multiple gpus. Partially remedy the situation by only
doing might_lock checks on drivers that do use struct_mutex still for
gem locking.

A more complete solution would be to do the mutex_init in the drm core
only for legacy drivers, plus add it to each modern driver that still
needs it, which would also give each its own lockdep key. Trying to do
that dynamically doesn't work, because lockdep requires it's keys to
be statically allocated.

It's not correct to encode the subsystem in the I2C device name, so
drop the -mfd suffix. To maintain bisect-ability, change driver and

Subject: mfd: retu: Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have a
OF device ID table if the devices are registered via OF.

Subject: tty/serial/fsl_lpuart: Add CONSOLE_POLL support for lpuart32.

This mirrors commit 2a41bc2a2b but for 32-bit register definitions.

Fix a minor typo while at it.

Subject: x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM
 mappings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ioremap() function is intended for mapping MMIO. For RAM, the
memremap() function should be used. Convert calls from ioremap() to
memremap() when re-mapping RAM.

This will be used later by SME to control how the encryption mask is
applied to memory mappings, with certain memory locations being mapped
decrypted vs encrypted.

Subject: iommu/amd: Allow the AMD IOMMU to work with memory encryption
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The IOMMU is programmed with physical addresses for the various tables
and buffers that are used to communicate between the device and the
driver. When the driver allocates this memory it is encrypted. In order
for the IOMMU to access the memory as encrypted the encryption mask needs
to be included in these physical addresses during configuration.

The PTE entries created by the IOMMU should also include the encryption
mask so that when the device behind the IOMMU performs a DMA, the DMA
will be performed to encrypted memory.

Subject: x86, drm, fbdev: Do not specify encrypted memory for video mappings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since video memory needs to be accessed decrypted, be sure that the
memory encryption mask is not set for the video ranges.

Subject: crypto: virtio - Refacotor virtio_crypto driver for new virito crypto
 services

In current virtio crypto device driver, some common data structures and
implementations that should be used by other virtio crypto algorithms
(e.g. asymmetric crypto algorithms) introduce symmetric crypto algorithms
specific implementations.
This patch refactors these pieces of code so that they can be reused by
other virtio crypto algorithms.

From 11105693fa05f499532b330da65c78ff93ed4440 Mon Sep 17 00:00:00 2001
From: Tudor-Dan Ambarus <tudor.ambarus@microchip.com>
Date: Wed, 5 Jul 2017 13:07:59 +0300
Subject: crypto: atmel-ecc - introduce Microchip / Atmel ECC driver

Add ECDH support for ATECC508A (I2C) device.

The device features hardware acceleration for the NIST standard
P256 prime curve and supports the complete key life cycle from
private key generation to ECDH key agreement.

Random private key generation is supported internally within
the device to ensure that the private key can never be known
outside of the device. If the user wants to use its own private
keys, the driver will fallback to the ecdh software implementation.

From 720419f01832f7e697cb80480b97b2a1e96045cd Mon Sep 17 00:00:00 2001
From: Brijesh Singh <brijesh.singh@amd.com>
Date: Thu, 6 Jul 2017 09:59:14 -0500
Subject: crypto: ccp - Introduce the AMD Secure Processor device

The CCP device is part of the AMD Secure Processor. In order to expand
the usage of the AMD Secure Processor, create a framework that allows
functional components of the AMD Secure Processor to be initialized and
handled appropriately.

From f4d18d656f882a7ca558313d5f1b18b1fd01f759 Mon Sep 17 00:00:00 2001
From: Brijesh Singh <brijesh.singh@amd.com>
Date: Thu, 6 Jul 2017 09:59:15 -0500
Subject: crypto: ccp - Abstract interrupt registeration

The CCP and PSP devices part of AMD Secure Procesor may share the same
interrupt. Hence we expand the SP device to register a common interrupt
handler and provide functions to CCP and PSP devices to register their
interrupt callback which will be invoked upon interrupt.

Subject: drm/i915: Fix cursor updates on some platforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Turns out that just writing CURPOS isn't sufficient to move the cursor
on some platforms. My 830 works just fine, but eg. 945 and PNV don't.
On those platforms we need to arm even the CURPOS update with a
CURBASE write.

Even worse, a write to any of the cursor register apart from CURBASE
will cancel an already pending cursor update. So if we have armed a
CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank
would cancel that armed update. Thus we're left with a cursor that
doesn't appear to move, or even change shape.

Fix the problem by always performing the CURBASE write after a
CURPOS write. Bspec is somewhat unclear which platforms actually
require this CURBASE write and which don't. So to keep it simple
and to make sure we really fix the problem across all supported
devices, let's just perform the CURBASE write unconditionally.

Subject: crypto: ccp - rename ccp driver initialize files as sp device

CCP device initializes is now integerated into higher level SP device,
to avoid the confusion lets rename the ccp driver initialization files
(ccp-platform.c->sp-platform.c, ccp-pci.c->sp-pci.c). The patch does not
make any functional changes other than renaming file and structures

Subject: crypto: ccp - remove ccp_present() check from device initialize

Since SP device driver supports multiples devices (e.g CCP, PSP), we
should not fail the driver init just because CCP device is not found.

Subject: crypto: caam/qi - fix compilation with DEBUG enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

caam/qi driver does not compile when DEBUG is enabled
(CRYPTO_DEV_FSL_CAAM_DEBUG=y):

drivers/crypto/caam/caamalg_qi.c: In function 'ablkcipher_done':
drivers/crypto/caam/caamalg_qi.c:794:2: error: implicit declaration of function 'dbg_dump_sg' [-Werror=implicit-function-declaration]
  dbg_dump_sg(KERN_ERR, "dst    @" __stringify(__LINE__)": ",

Since dbg_dump_sg() is shared between caam/jr and caam/qi, move it
in a shared location and export it.

At the same time:
-reduce ifdeferry by providing a no-op implementation for !DEBUG case
-rename it to caam_dump_sg() to be consistent in terms of
exported symbols namespace (caam_*)

Subject: crypto: caam/qi - handle large number of S/Gs case
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For more than 16 S/G entries, driver currently corrupts memory
on ARMv8, see below KASAN log.
Note: this does not reproduce on PowerPC due to different (smaller)
cache line size - 64 bytes on PPC vs. 128 bytes on ARMv8.

One such use case is one of the cbc(aes) test vectors - with 8 S/G
entries and src != dst. Driver needs 1 (IV) + 2 x 8 = 17 entries,
which goes over the 16 S/G entries limit:
(CAAM_QI_MEMCACHE_SIZE - offsetof(struct ablkcipher_edesc, sgt)) /
sizeof(struct qm_sg_entry) = 256 / 16 = 16 S/Gs

Fix this by:
-increasing object size in caamqicache pool from 512 to 768; this means
the maximum number of S/G entries grows from (at least) 16 to 32
(again, for ARMv8 case of 128-byte cache line)
-add checks in the driver to fail gracefully (ENOMEM) in case the 32 S/G
entries limit is exceeded

Associated data (AD) length is read by CAAM from an S/G entry
that is initially filled by the GPP.
Accordingly, AD length has to be stored in CAAM endianness.

Subject: hwrng: use rng source with best quality

This patch rewoks the hwrng to always use the
rng source with best entropy quality.

On registation and unregistration the hwrng now
tries to choose the best (= highest quality value)
rng source. The handling of the internal list
of registered rng sources is now always sorted
by quality and the top most rng chosen.

Subject: hwrng: remember rng chosen by user

When a user chooses a rng source via sysfs attribute
this rng should be sticky, even when other sources
with better quality to register. This patch introduces
a simple way to remember the user's choice. This is
reflected by a new sysfs attribute file 'rng_selected'
which shows if the current rng has been chosen by
userspace. The new attribute file shows '1' for user
selected rng and '0' otherwise.

Subject: spi: loopback-test: make several module parameters static

Several module parameters are local to the source, so make them
static. Cleans up several sparse warnings such as:

"symbol 'loop_req' was not declared. Should it be static?"

Subject: pinctrl: samsung: Fix NULL pointer exception on external interrupts
 on S3C24xx

After commit 8b1bd11c1f8f ("pinctrl: samsung: Add the support the
multiple IORESOURCE_MEM for one pin-bank"), the S3C24xx (and probably
S3C64xx as well) fails:

	Unable to handle kernel NULL pointer dereference at virtual address 000000a8
	...
	(s3c24xx_demux_eint4_7) from [<c004469c>] (__handle_domain_irq+0x6c/0xcc)
	(__handle_domain_irq) from [<c0009444>] (s3c24xx_handle_irq+0x6c/0x12c)
	(s3c24xx_handle_irq) from [<c000e5fc>] (__irq_svc+0x5c/0x78)

Mentioned commit moved the pointer to controller's base IO memory address
from each controller's driver data (samsung_pinctrl_drv_data) to per-bank
structure (samsung_pin_bank).  The external interrupt demux
handlers (s3c24xx_demux_eint()) tried to get this base address from opaque
pointer stored under irq_chip data:

	struct irq_data *irqd = irq_desc_get_irq_data(desc);
	struct samsung_pin_bank *bank = irq_data_get_irq_chip_data(irqd);
	...
	pend = readl(bank->eint_base + EINTPEND_REG);

which is wrong because this is hardware irq and it bank was never set
for this irq_chip.

For S3C24xx and S3C64xx, this partially reverts mentioned commit by
bringing back the virt_base stored under each controller's driver data
(samsung_pinctrl_drv_data).  This virt_base address will be now
duplicated:
 - samsung_pinctrl_drv_data->virt_base: used on S3C24xx and S3C64xx,
 - samsung_pin_bank->pctl_base: used on Exynos.

Fixes: 8b1bd11c1f8f ("pinctrl: samsung: Add the support the multiple IORESOURCE_MEM for one pin-bank")

Subject: dmaengine: dmatest: add support for memset test

Introducing memset test into dmatest. This change allows us to test
memset capable HW using the dmatest test procedure. The new dmatest
value for memset is 2 and it is not the default value.

Memset support patch shares the same code path as the other dmatest
code to reuse as much as we can.

The first value inside the source buffer is used as a pattern
to fill in the destination buffer space.

Prior to running the test, source/destination buffers are initialized
in the current code.

"The remaining bits are the inverse of a counter which increments by
 one for each byte address."

Memset test will fill in the upper bits of pattern with the inverse of
fixed counter value 1 as opposed to an incrementing value in a loop.

An example run is as follows:

echo dma0chan0 > /sys/module/dmatest/parameters/channel
echo 2 >  /sys/module/dmatest/parameters/dmatest
echo 2000 >  /sys/module/dmatest/parameters/timeout
echo 10 >  /sys/module/dmatest/parameters/iterations
echo 1 >  /sys/module/dmatest/parameters/run

Subject: sun4i_hdmi: add CEC support

Add HDMI CEC support to the Allwinner A10 SoC.

This SoC uses a poor-man's CEC implementation by polling the CEC pin. It is
using the CEC_PIN core implementation for such devices to do the heavy
lifting. It just provides the callbacks to read/drive the CEC pin.

From a85c6f1b2921cbd2f54666a52804f407c4a064fe Mon Sep 17 00:00:00 2001
From: Stefan Roese <sr@denx.de>
Date: Fri, 7 Jul 2017 14:11:19 +0200
Subject: dmaengine: Add driver for Altera / Intel mSGDMA IP core

This driver adds support for the Altera / Intel modular Scatter-Gather
Direct Memory Access (mSGDMA) intellectual property (IP) to the Linux
DMAengine subsystem. Currently it supports the following op modes:

- DMA_MEMCPY
- DMA_SG
- DMA_SLAVE

This implementation has been tested on an Altera Cyclone FPGA connected
via PCIe, both on an ARM and an x86 platform.

Subject: pinctrl: samsung: Fix invalid register offset used for Exynos5433
 external interrupts

When setting the pin function for external interrupts, the driver used
wrong IO memory address base.  The pin function register is always under
pctl_base, not the eint_base.

By updating wrong register, the external interrupts for chosen GPIO
would not work at all and some other GPIO might be configured to wrong
value.  For example on Exynos5433-based boards, the external interrupts
for gpf{1-5}-X GPIOs should not work at all (driver toggled reserved
registers from ALIVE bank instead).

Platforms other than Exynos5433 should not be affected as eint_base
equals pctl_base in such case.

Fixes: 8b1bd11c1f8f ("pinctrl: samsung: Add the support the multiple IORESOURCE_MEM for one pin-bank")

Subject: net: dsa: mv88e6xxx: add number of Global 2 IRQs

Similarly to g1_irqs, add a g2_irqs member to the info structure to
indicates the presence of the Global 2 Interrupt Source and Mask
registers.

At the same time, provide helpers and document the registers since they
differ a bit between 88E6352 and 88E6390 families.

This allows us to get rid of the MV88E6XXX_FLAG_G2_INT flag.

Subject: net: dsa: mv88e6xxx: distinguish Global 2 Rsvd2CPU

The 88E6185 family only has one 16-bit register to mark the 16 802.1D
reserved multicast addresses in the range of 01:80:C2:00:00:0x as MGMT.

The 88E6352 family also has one 16-bit register to mark the 16 GARP
reserved multicast addresses in the range of 01:80:C2:00:00:2x as MGMT.

Split the existing mv88e6095 prefixed mgmt_rsvd2cpu operation into two
distinct mv88e6185 and mv88e6352 prefixed operations, and wrap its call
into a mv88e6xxx_rsvd2cpu_setup helper.

This allows us to also get rid of the MV88E6XXX_CAP_G2_MGMT_EN_* flags.

Subject: net: dsa: mv88e6xxx: add POT flag to 88E6390

The 88E6390 family clear the Priority Override Table the same way as
88E6352, thus add MV88E6XXX_FLAG_G2_POT to MV88E6XXX_FLAGS_FAMILY_6390.

Subject: net: dsa: mv88e6xxx: add POT operation

Add a pot_clear operation to clear the Priority Override Table and wrap
its call into a mv88e6xxx_pot_setup helper.

This allows us to get rid of the MV88E6XXX_FLAG_G2_POT flag.

Subject: net: dsa: mv88e6xxx: add a global2_addr info flag

Similarly to global1_addr, add a global2_addr member in the info
structure to describe the presence of the Global 2 Registers.

This allows us to get rid of the MV88E6XXX_FLAG_GLOBAL2 flag.

Subject: net: dsa: mv88e6xxx: add Energy Detect ops

The 88E6352 family supports Energy Detect and has one bit for Sense and
one bit for periodically transmit NLP (Energy Detect+TM). The 88E6390
family adds another bit to distinguish Auto or SW wake-up. Chips
supporting EEE all have an EEE Enabled bit in the Port Status Register.

This patch adds new ops for the PHY Energy Detect accesses.

This also allows us to get rid of the MV88E6XXX_FLAG_EEE flag.

Subject: net: dsa: mv88e6xxx: add a multi_chip info flag

Instead of relying on a bitmap flag, add a new multi_chip info flag to
describe the presence of the indirect SMI access though the two device
registers 0x0 and 0x1.

All remaining capabilities and flags are now unused. Remove the
mv88e6xxx_cap enum and the info flags bitmaps.

Subject: drivers: net: add missing interrupt.h include

these drivers use tasklets or irq apis, but don't include interrupt.h.
Once flow cache is removed the implicit interrupt.h inclusion goes away
which will break the build.

Subject: mlxsw: spectrum: Add support for IPv6 traps

Before we can start using IPv6, we need to trap certain control packets
to the CPU. Among others, these include Neighbour Discovery, DHCP and
neighbour misses.

Subject: mlxsw: spectrum_router: Flood unregistered multicast packets to
 router

Up until now we only flooded broadcast packets to the router when an L3
interface was configured on top of a bridge. However, IPv6 Neighbour
Discovery packets are trapped to the CPU inside the router and these can
be sent with a multicast address.

Flood unregistered multicast packets to the router port, so that
relevant packets could be trapped there.

Subject: mlxsw: spectrum_router: Configure RIFs based on IPv6 addresses

When a netdev is configured with an IP address a router interface (RIF)
should be configured for it in the device. Allow configuration of RIFs
based on IPv6 address notifications as well as IPv4.

Note that the RIF exists as long as an IP address is configured on the
netdev, regardless of the address family.

Subject: mlxsw: spectrum_router: Reflect IPv6 neighbours to the device

As with IPv4, listen to NEIGH_UPDATE events from the ndisc table and
program relevant neighbours to the device's neighbour table.

Note that neighbours with a link-local IP address aren't programmed, as
packets with a link-local destination IP are trapped after LPM lookup
and never reach the neighbour table.

should set the interval according to the minimum between the ARP and
ndisc tables.

Subject: mlxsw: spectrum_router: Don't assume neighbour type

Thankfully, the neighbour subsystem is agnostic to the upper protocol
and used by both IPv4 and IPv6. By removing assumptions regarding the
neighbour type we can thus re-use much of the neighbour-related code for
both IPv4 and IPv6.

For each nexthop, store its gateway IP and for nexthop group store the
neighbour table used by its nexthops.

Use this information throughout the code and remove assumption about the
neighbour type.

Subject: mlxsw: spectrum_router: Don't create FIB node during lookup

When looking up a FIB entry we shouldn't create the FIB node where it's
supposed to be linked in case the node doesn't already exist.

Instead, lookup the node and fail if it doesn't exist.

Subject: mlxsw: spectrum_router: Make FIB node retrieval family agnostic

A FIB node is an entity which stores routes sharing the same prefix and
length. The data structure itself is already family agnostic, but we
make some of its operations agnostic as well and thus re-use them for
IPv6 offload.

Instead of passing an IPv4-specific structure to fib4_node_get(), pass
general routing parameters and rename the function accordingly.

Subject: mlxsw: spectrum_router: Extend virtual routers with IPv6 support

A Virtual Router (VR) is an entity which corresponds to a VRF and
performs FIB lookup in an LPM tree according to the {VR, IP Proto} ->
Tree binding.

Extend the virtual router data structure towards IPv6 FIB offload.

Take advantage of previous patch and allow the RALUE register to be

In order to re-use as much code as possible between IPv4 and IPv6, only
the lowest-level function that actually does the register packing is
demuxed based on the passed protocol.

Subject: mlxsw: spectrum_router: Set abort trap for IPv6

When we fail to insert a route we invoke the abort mechanism which
flushes all the tables and inserts a default route in each, so that all
packets incoming to the router will be trapped to the CPU.

Upon abort, add an IPv6 default route to the IPv6 tables.

Subject: mlxsw: spectrum_router: Create IPv4 specific entry struct

Some of the parameters stored in the FIB entry structure are specific to
IPv4 and therefore better placed in an IPv4 specific structure.

Create an IPv4 specific structure that encapsulates the common FIB entry
structure and contains IPv4 specific parameters.

In a follow-up patchset an IPv6 specific structure will be introduced.

Subject: mlxsw: spectrum_router: Mark IPv4 specific function accordingly

The functions to create and destroy a nexthop group are IPv4 specific
and should be renamed accordingly, so that they won't be confused with
the IPv6 specific functions in follow-up patches.

Functions that take as argument a FIB entry don't need to take FIB node
as well, as it can be extracted from the entry.

Remove unnecessary FIB node parameter.

Subject: mlxsw: spectrum_router: Update prefix count for IPv6

The number of possible prefix lengths for IPv6 is 129 and not 128.

Fixes following warning from UBSAN when /128 routes are offloaded:

 UBSAN: Undefined behaviour in
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:2510:27 index 128 is out
of range for type 'long unsigned int [128]'

Subject: Input: trackpoint - assume 3 buttons when buttons detection fails

Trackpoint buttons detection fails on ThinkPad 570 and 470 series,
this makes the middle button of the trackpoint to not being recogized.
As I don't believe there is any trackpoint with less than 3 buttons this
patch just assumes three buttons when the extended button information
read fails.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: dmaengine: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: dmaengine: qcom_hidma: introduce memset support

HIDMA HW supports memset operation in addition to memcpy.
Since the memset API is present on the kernel now, bring the
memset feature into life.

The descriptor format is the same for both memcpy and memset.
Type of the descriptor is 4 when memset is requested.
The lowest 8 bits of the source DMA argument is used as a
fill pattern.

Subject: dmaengine: qcom_hidma: correct overriding message

A false overriding information is being presented during boot
under this scenario.

1. First object checks for kernel command line value against zero.
2. It doesn't find it, it sets the command line variable to the
value coming from ACPI/DT.
3. Second object is being probed.
4. Second object sees that the value of kernel command line
override is non-zero, it prints an overriding message even though
value matches ACPI/DT value.

hidma-mgmt QCOM8060:03: overriding max-write-burst-bytes: 1024

Add an additional check to verify that kernel command line value
is different from the ACPI/DT value.

Subject: pinctrl: samsung: Consistently use unsigned instead of u32 for
 nr_banks

Unlike for other countable members, the driver used u32 for number of
banks (nr_banks).  There is no specific need for using fixed-width
integer in this particular place.  Make it consistent.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing of

Subject: reset: Add APIs to manage array of resets

Many devices may want to request a bunch of resets and control them. So
it's better to manage them as an array. Add APIs to _get() an array of
reset_control, reusing the _assert(), _deassert(), and _reset() APIs for
single reset controls. Since reset controls already may control multiple
reset lines with a single hardware bit, from the user perspective, reset
control arrays are not at all different from single reset controls.
Note that these APIs don't guarantee that the reset lines managed in the
array are handled in any particular order.

Subject: reset: make (de)assert report success for self-deasserting reset
 drivers

By now there are drivers using shared reset controls and (de)assert
calls on platforms with self-deasserting reset lines and thus reset
drivers that do not implement .assert() and .deassert().
As long as the initial state of the reset line is deasserted, there
is no reason for a reset_control_assert call to return an error for
shared reset controls, or for a reset_control_deassert call to return
an error for either shared or exclusive reset controls: after a call
to reset_control_deassert the reset line is guaranteed to be deasserted,
and after a call to reset_control_assert it is valid for the reset
line to stay deasserted for shared reset controls.

The error will occur if the configuration is set to:

If CONFIG_OF_DYNAMIC is enabled then of_node_release() detects an

ddb_allocation && ddb_allocation / blocks_per_line >= 1 is the same

this.

This fixes the following compiler warning:

Subject: drm/i915: Drain the device workqueue on unload

Workers on the i915->wq may rearm themselves so for completeness we need
to replace our flush_workqueue() with a call to drain_workqueue() before
unloading the device.

v2: Reinforce the drain_workqueue with an preceding rcu_barrier() as a
few of the tasks that need to be drained may first be armed by RCU.

Subject: drm/atomic-helper: Fix leak in disable_all

The legacy plane->fb pointer is refcounted by calling
drm_atomic_clean_old_fb().

In practice this isn't a real problem because:
- The caller in the i915 gpu reset code restores the original state
  again, which means the plane->fb pointer won't change, hence can't
  leak.
- Drivers using drm_atomic_helper_shutdown call the fbdev cleanup
  first, and that usually cleans up the fb through
  drm_remove_framebuffer, which does this correctly.
- Without fbdev the only framebuffers are from userspace, and those
  get cleaned up (again using drm_remove_framebuffer) befor the driver
  can even be unloaded.

But in i915 I've switched the cleanup sequence around so that the
_shutdown() calls happens after the drm_remove_framebuffer(), which is
how I discovered this issue.

v2: My analysis why the current code was ok for gpu reset and
suspend/resume was correct, but then I totally failed to realize that
we better keep this symmetric. Thanksfully CI noticed that for
balance, a refcounting bug must exist at 2 places if previously there
was no issue ...

v3: Don't be lazy and compute the plane_mask in
commit_duplicated_state properly too, instead of just using ~0U.

Subject: drm/i915: Fix fbdev unload sequence

First thing we need to do is unregister the fbdev instance, but we
can't just go ahead and kfree it. That must wait until the hotplug and
polling work are stopped, since they can race with the with the
teardown. That means we need to split up the fbdev teardown into the
unregister part and the cleanup part.

I originally suspected that this was broken in one of the unload
shuffles, but on closer inspection the oldest sequence I've dug out
also gets this wrong. Just not quite so badly.

I've run drv_module_reload a few hundred times and it's rock solid
compared to insta-death beforehand. This bug seems to have been
uncovered by

commit 88be58be886f1215cc73dc8c273c985eecd7385c
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Thu Jul 6 15:00:19 2017 +0200

    drm/i915/fbdev: Always forward hotplug events

But the effect of that seems to only be to increase the race window
enough to make it blow up easier. I'm not exactly clear on what's
going on there ...

v2: Fix whitespace and use fetch_and_zero (Chris).

Subject: clk: renesas: rcar-gen3-cpg: Refactor checks for accessing the div
 table

Do the checks for accessing the SD divider table only when the rate gets
updated, namely on init and set_rate. In all other cases, reuse the last
value. This simplifies code, runtime load, and error reporting.

Subject: drm/i915/selftests: Mark contexts as lost during freeing of mock
 device

We need to unpin the last retired context early in the shutdown sequence
so that its RCU free is done before we try to free the context ida. I
included this in a later patch ("drm/i915: Keep a recent cache of freed
contexts objects for reuse") and so missed that the selftests were broken
in the meantime.

Subject: mtd: nand: atmel: Fix DT backward compatibility in pmecc.c

PMECC caps extraction from old DT bindings is broken, thus leading to
erroneous EL registers offset, which in turn make HW ECC unusable on
sama5d2 when old bindings are in use.

Passing the NAND dev node instead of the NFC node to of_match_node()
solves the problem.

Subject: ISDN: eicon: switch to use native bitmaps

Two arrays are clearly bit maps, so, make that explicit by converting to
bitmap API and remove custom helpers.

Note sig_ind() uses out of boundary bit to (looks like) protect against
potential bitmap_empty() checks for the same bitmap.

This patch removes that since:
1) that didn't guarantee atomicity anyway;
2) the first operation inside the for-loop is set bit in the bitmap
   (which effectively makes it non-empty);
3) group_optimization() doesn't utilize possible emptiness of the bitmap
   in question.

Thus, if there is a protection needed it should be implemented properly.

Subject: wireless: airo: remove unnecessary static in writerids()

Remove unnecessary static on local function pointer _writer_.
Such pointer is initialized before being used, on every
execution path throughout the function. The static has no
benefit and, removing it reduces the object file size.

This issue was detected using Coccinelle and the following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see a significant difference in the object
file size. This log is the output of the size command, before and after
the code change:

Subject: liquidio: lio_vf_main: remove unnecessary static in setup_io_queues()

Remove unnecessary static on local variables cpu_id_modulus and cpu_id.
Such variables are initialized before being used, on every execution
path throughout the function. The static has no benefit and, removing
it reduces the object file size.

This issue was detected using Coccinelle and the following semantic patch:

@bad exists@

In the following log you can see a significant difference in the object
file size. Also, there is a significant difference in the bss segment.
This log is the output of the size command, before and after the code
change:

Subject: netvsc: force link update after MTU change

If two MTU changes are in less than update interval (2 seconds),
then the netvsc network device may get stuck with no carrier.

The netvsc driver debounces link status events which is fine
for unsolicited updates, but blocks getting the update after
down/up from MTU reinitialization.

This fixes the error unwind logic for incorrect number of queues.
If netif_set_real_num_XX_queues failed then rndis_filter_device_add
would have been called twice. Since input arguments are already
ranged checked this is a hypothetical only problem, not possible
in actual code.

probe context and RTNL context,and creates the netvsc_device
inner structure. It is easier to get the RTNL lock annotation
correct if it returns the object directly, rather than implicitly
by updating network device private data.

Subject: netvsc: need rcu_derefence when accessing internal device info

The netvsc_device structure should be accessed by rcu_dereference
in the send path.  Change arguments to netvsc_send() to make
this easier to do correctly.

Remove no longer needed hv_device_to_netvsc_device.

Subject: drm/i915: Pass enum pipe to intel_set_pch_fifo_underrun_reporting()

Commit a21960339c8c ("drm/i915: Consistently use enum pipe for PCH
transcoders") misses some pieces, due to a problem with the patch
format, this patch adds the remaining bits.

Just a very minimal patch to nuke that code. Lots of the flip
interrupt handling stuff is still around.

Subject: drm/i915: Unbreak gpu reset vs. modeset locking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Taking the modeset locks unconditionally isn't the greatest idea,
because atm that part is still broken and times out (and then atomic
keels over). And there's really no reason to do so, the old code
didn't do that either.

To make the patch a bit simpler let's also nuke 2 cases that are only
around for the old mmioflip paths. Atomic nonblocking workers will not
die (minus bugs) when a gpu reset happens.

And of course this doesn't fix any of the gpu reset vs. modeset
deadlock fun, but it at least stop modern CI machines from keeling
over all over the place for no reason at all.

And we still have the explicit testcases to run the fake gpu reset, so
coverage isn't that much worse.

v2: Split out additional changes on top, restrict this to purely reducing
the critical section of modeset locks.

v2: Review from Maarten
- update comments
- don't oops when state is NULL in intel_finish_reset, but try to at
  least still drop locks properly. The hw is going to be toast anyway.

Fixes: 739748939974 ("drm/i915: Fix modeset handling during gpu reset, v5.")

Subject: Bluetooth: btwilink: remove unnecessary static in bt_ti_probe()

Remove unnecessary static on local variable hst.
Such variable is initialized before being used,
on every execution path throughout the function.
The static has no benefit and, removing it reduces
the object file size.

This issue was detected using Coccinelle and the
following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:

before:
   text    data     bss     dec     hex filename
   4029    2528     128    6685    1a1d drivers/bluetooth/btwilink.o

Subject: x86/boot: Fix memremap() related build failure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The following commit:

  5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data")

causes new build failures on certain randconfigs:

  drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’:
  drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration]
  drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function)

This is a case of parasitic header dependencies: the sfi_core.c file indirectly
includes <linux/io.h> for typical - but not all configs.

Including <linux/io.h> explicitly solves the build failure.

Subject: regulator: fan53555: Use of_device_get_match_data() to simplify probe

if fan53555_regulator_probe() is called and the "client->dev.of_node"
isn't NULL, it means OF registered a device with a valid compatible
string, so match cannot be NULL.

Use of_device_get_match_data() to retrieve the drvdata pointer.  No
functional change intended.

Subject: regulator: core: fix a possible race in disable_work handling

A race condition between queueing and processing the disable_work
instances results in having a work instance in the queue and the
deferred_disables variable of regulator device structure having a
value '0'. If no new regulator_disable_deferred() call later from
clients, the deferred_disables variable value remains '0' and hits
BUG() in regulator_disable_work() when the queued instance scheduled
for processing the work.

The race occurs as below:

	Core-0					     Core-1
	.....	       /* deferred_disables = 2 */   .....
	.....	       /* disable_work is queued */  .....
	.....					     .....
regulator_disable_deferred: 		regulator_disable_work:
   mutex_lock(&rdev->mutex);			     .....
   rdev->deferred_disables++;		             .....
   mutex_unlock(&rdev->mutex);			     .....
   queue_delayed_work(...)		    mutex_lock(&rdev->mutex);
	.....				    count =rdev->deferred_disables;
	.....				    rdev->deferred_disables = 0;
	.....					     .....
	.....				    mutex_unlock(&rdev->mutex);
	.....					     .....
	.....				    return;
	.....					     .....
	/* No new regulator_disable_deferred() calls from clients */
	/* The newly queued instance is scheduled for processing */
	.....					     .....
regulator_disable_work:
	.....
   mutex_lock(&rdev->mutex);
   BUG_ON(!rdev->deferred_disables); /* deferred_disables = 0 */

The race is fixed by removing the work instance that is queued while
processing the previous queued instance. Cancel the newly queued instance
from disable_work() handler just after reset the deferred_disables variable
to value '0'. Also move the work queueing step before mutex_unlock in
regulator_disable_deferred().

Also use mod_delayed_work() in the pace of queue_delayed_work() as
queue_delayed_work() always uses the delay requested in the first call
when multiple consumers call regulator_disable_deferred() close in time
and does not guarantee the semantics of regulator_disable_deferred().

Subject: HID: asus: Add support for T100 touchpad

Add support for the Asus T100 touchpad in multi-touch mode (rather
then mouse emulation mode). It turns out that the Asus T100 touchpad
is identical to the already supported i2c-hid Asus touchpads, so
adding support for it was easy.

The only significant difference is that the reported x-coordinates
range on the T100 touchpad is somewhat lower then the range on the
already supported touchpads.

Instead of having hardcoded (#define-d) values use a struct describing
the various touchpad parameters. This is a preparation patch for
improving the T100TA touchpad support as well as for adding T100CHI
touchpad support.

Subject: HID: asus: Fix T100TA touchpad y dimensions

When adding the initial support I only looked at the maximum coordinates
but the Y axis is inverted, so I should have checked the minimum
coodinates which never reach 0 due to max_y being wrong, fix this.

Subject: HID: asus: Add T100CHI bluetooth keyboard dock special keys mapping

The Asus Transformer T100CHI comes with a Bluetooth keyboard dock which
uses the same 0xff31 Asus vendor HUT page as other Asus keyboards.

This commit adds its device-id to hid-asus and fixes an issue in the
descriptor of the 0xff31 Usage, which together fixes the special keys
on this keyboard not working.

Subject: of: overlay: add overlay unittest data for node names and symbols

Add nodes and properties to overlay_base and overlay dts files to
test for
   - incorrect existing node name detection when overlay node name
     has a unit-address
   - adding overlay __symbols__ properties to live tree when an
     overlay is added to the live tree

The following console messages will appear near the end of unittest
until the code errors are corrected:

   OF: Duplicate name in fairway-1, renamed to "ride@100#1"

   ### dt-test ### FAIL of_unittest_overlay_high_level():2296 Adding overlay 'overlay_bad_symbol' failed

   ### dt-test ### end of unittest - 190 passed, 1 failed

Subject: of: overlay: correctly apply overlay node with unit-address

Correct existing node name detection when overlay node name has
a unit-address.

Expected test result is overlay will update the nodes and properties
for /testcase-data-2/fairway-1/ride@100/ after this commit.

Before this commit:

   Console error message near end of unittest:
      OF: Duplicate name in fairway-1, renamed to "ride@100#1"

   $ cd /proc/device-tree/testcase-data-2/fairway-1/
   $ # extra node: ride@100#1
   $ ls
   #address-cells  linux,phandle   phandle         ride@200
   #size-cells     name            ride@100        status
   compatible      orientation     ride@100#1
   $ cd /proc/device-tree/testcase-data-2/fairway-1/ride@100/
   $ ls track@30/incline-up
   ls: track@30/incline-up: No such file or directory
   $ ls track@40/incline-up
   ls: track@40/incline-up: No such file or directory

After this commit:

   Console error message no longer occurs

   $ cd /proc/device-tree/testcase-data-2/fairway-1/
   $ # no extra node: ride@100#1
   $ ls
   #address-cells  compatible      name            phandle         ride@200

Subject: ACPICA: iASL compiler: allow compilation of externals with paths that
 refer to existing names

ACPICA commit 9a252114197409290813bee570e9d53c22b99d32

This change allows compilation of code like the following:

definition_block (...)
{
    External (ABCD.EFGH)
    Device (ABCD)
    {
        Name (IJLK,0)
    }
}

but does not allow compilation of code like the following:

definition_block (...)
{
    External (ABCD)
    Device (ABCD)
    {
        Name (EFGH,0)
    }
}

ACPICA commit 47538f5f0773c0820d8f552e20f6e77104290c01

The following commit is not correctly linuxized by its ACPICA form (see
link #1 for reference):
  Commit: 3d867f6c5fd6535cdeceef3170e5e84e5dd80fc1
  Subject: ACPICA: Use designated initializers
Thus breaks linuxize process.

Subject: ACPICA: linuxize: cleanup typedef definitions

ACPICA commit 894e49ef22db354eb1685cdb6f5f991766351d3c

acpisrc now has capability to convert both the followings:
1. Form 1:
  typedef struct/union foo {         struct/union foo {
     ....                       -->      ...
  } FOO;                             }
2. Form 2:
  typedef struct/union foo FOO; -->  typedef struct/union foo foo;
It becomes unable to handle the following:
3. Form3:
  typedef struct/union foo { /* comment */
      ...
  } FOO;
    -->
  strut/union foo { /* comment */
      ...
  };

As:
1. The purpose of acpisrc is to convert formatted code (ACPICA coding
   style) into linux coding style,
2. acpisrc is a very simple tool that doesn't fully handle C language.
This commit changes the definitions side in order not to regress and we
shall make "no comments in struct/union line" as a new ACPICA coding style
rule. Lv Zheng.

Subject: ACPICA: Tables: Add sanity check in acpi_put_table()

ACPICA commit 73512384c9eb1e7f1b28d0a7372df26a3732f96b

To avoid caller to trigger unexpected warning messages (Link #1):
  ACPI Warning: Table ffffffffbb461d20, Validation count is zero before decrement
Which is reported from acpi_tb_put_table(). When the table is validated, the
pointer must be non-zero. Thus the message is not suitable for invalidated
tables. This patch fixes the callee side based on this fact. Reported by
Cristian Aravena Romero, Fixed by Lv Zheng.

Subject: ACPICA: Tables: Do not validate signature for dynamic table load

ACPICA commit d3c944f2cdc8c7e847b7942b1864f285189f7bce

Windows seems to allow arbitrary table signatures for Load/load_table
opcodes:
  ACPI BIOS Error (bug): Table has invalid signature [PRAD] (0x44415250)
So this patch removes dynamic load signature checks. However we need to
find a way to avoid table loading against tables like MADT. This is not
covered by this commit.

This Windows behavior has been validated on link #1. An end user bug
report can also be found on link #2.

This patch also includes simple cleanup for static load signature check
code. Reported by Ye Xiaolong, Fixed by Lv Zheng.

Subject: ACPICA: Tables: Change table duplication check to be related to
 acpi_gbl_verify_table_checksum

ACPICA commit 3d837b5d4b1033942b4d91c7d3801a09c3157918

acpi_gbl_verify_table_checksum is used to avoid validating (mapping) an entire
table in OS boot stage. 2nd "Reload" check in acpi_tb_install_standard_table()
is prepared for the same purpose. So this patch combines them together
using a renamed acpi_gbl_enable_table_validation flag. Lv Zheng.

Subject: ACPICA: Tables: Combine checksum/duplication verification together

ACPICA commit 182bdffc0644f568be614a6d4debd651e29ca587

They are all mechanisms used to verify if a table is qualified to be
installed and controlled by acpi_gbl_enable_table_validation, so combine them
together. By doing so, table duplication check is applied to the statically
loaded tables (however whether it is actually enabled is still determined
by acpi_gbl_enable_table_validation). Lv Zheng.

Subject: ACPICA: Tables: Add deferred table verification support

ACPICA commit 2dd6c151d5d5e76dacba8f7db9e259fc72982d17
ACPICA commit ffddee6638aced83be18b8bc88569586c1a43e03

This patch allows tables not verified in early stage verfied in
acpi_reallocate_root_table(). This is useful for OSPMs like linux where tables
cannot be verified in early stage due to early ioremp limitations on some
architectures. Reported by Hans de Geode, fixed by Lv Zheng.

Subject: ACPICA: iASL: Ensure that the target node is valid in
 acpi_ex_create_alias

ACPICA commit 8b14afac65d983610cc5387ede6d85ea5ee075be

The following ACPI table contains an invalid target node within the
Alias operator:

definition_block ("", "SSDT", 1, "Bug", "BugTable", 0x00001000)
{
    Scope (_SB)
    {
        Device (DEV0)
        {
            Name (_ADR, 1)

            Device (DEV1)
            {
                Alias (_ADR, _ADR)
            }
        }
    }
}

If an ACPI table contains such an invalid target node in an Alias
operator, a segmentation fault will occur when the target node is
dereferenced within acpi_ex_create_alias. Add a check for such an invalid
target node in acpi_ex_create_alias and return AE_NULL_OBJECT as suggested
by @acpibob.

Subject: of: overlay: add overlay symbols to live device tree

Add overlay __symbols__ properties to live tree when an overlay
is added to the live tree so that the symbols are available to
subsequent overlays.

Expected test result is new __symbols__ entries for labels from
the overlay after this commit.

Before this commit:

   Console error message near end of unittest:
      ### dt-test ### FAIL of_unittest_overlay_high_level():2296 Adding overlay 'overlay_bad_symbol' failed
      ### dt-test ### end of unittest - 190 passed, 1 failed

   The new unittest "fails" because the expected result of loading the
   new overlay is an error instead of success.

   $ # node hvac-medium-2 exists because the overlay loaded
   $ # since the duplicate symbol was not detected
   $ cd /proc/device-tree/testcase-data-2/substation@100/
   $ ls
   compatible     hvac-medium-2  motor-8        reg
   hvac-large-1   linux,phandle  name           status
   hvac-medium-1  motor-1        phandle

   $ cd /proc/device-tree/__symbols__/
   $ ls
   electric_1   lights_1     name         rides_1      spin_ctrl_2
   hvac_1       lights_2     retail_1     spin_ctrl_1

After this commit:

   Previous console error message no longer occurs, but expected error
   occurs:
      OF: overlay: Failed to apply prop @/__symbols__/hvac_1
      OF: overlay: apply failed '/__symbols__'
      ### dt-test ### end of unittest - 191 passed, 0 failed

   $ # node hvac-medium-2 does not exist because the overlay
   $ # properly failed to load due to the duplicate symbol
   $ cd /proc/device-tree/testcase-data-2/substation@100/
   $ ls

Subject: drm/i915: Rip out legacy page_flip completion/irq handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All these races and things are now solved through the vblank evasion
trick, plus event handling is done using normal vblank even processing
and drm_crtc_arm_vblank_event. We can get rid of all this complexity.

A bit an oversight - the current code did nothing, since only
legacy flips used the unpin_work_count and assorted logic.

Subject: drm/i915: Remove intel_flip_work infrastructure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This gets rid of all the interactions between the legacy flip code and
the modeset code. Yay!

This highlights an ommission in the atomic paths, where we fail to
apply a boost to the pending rendering when we miss the target vblank.
But the existing code is still dead and can be removed.

v2: Note that the boosting doesn't work in atomic (Chris).

Subject: drm/i915: Drop unpin stall in atomic_prepare_commit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The core already does this in setup_commit(). With this we can also
remove the unpin_work_count since it's the last user, and also remove
the loop since that was only used for stalling against legacy flips.

v2: Amend commit message a bit (Chris).

Subject: Revert "drm/i915: Add option to support dynamic backlight via DPCD"

This reverts commit ae25eceab616d16a07bcaa434b84463d58a3bdc3.

The DPCD backlight commits regress a Thinkpad X1 Carbon 4th Gen and a
BXT-P (in CI). Enabling dynamic backlight boots to a black screen, and
enabling DPCD backlight leads to a black screen after suspend/resume.

Subject: dmaengine: ppc4xx: remove DRIVER_ATTR() usage

It's better to be explicit and use the DRIVER_ATTR_RW() and
DRIVER_ATTR_RO() macros when defining a driver's sysfs file.

Bonus is this fixes up a checkpatch.pl warning.

This is part of a series to drop DRIVER_ATTR() from the tree entirely.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When phy-sun4i-usb's probing fails, it does not print the reason in
kernel log, forcing the developer to edit this driver to add info logs.
This commit makes the kernel print the reason of phy-sun4i-usb's probing
failure or a success message.

Subject: of: irq: use of_property_read_bool() for "interrupt-controller" prop

The "interrupt-controller" property is boolean, i.e. has no value.  The DT
interrupt parsing code predates of_property_read_bool(), so it uses either
of_get_property() or of_find_property() -- the former isn't quite correct
for the boolean props (but works somehow). Use the modern boolean prop API
instead.

Subject: of: irq: use of_property_read_u32()

The DT interrupt parsing code predates of_property_read_u32(), so it has to
basically open-code it. Using the modern DT API saves several LoCs and also
adds some prop sanity checks as a bonus...

Subject: mtd: create per-device and module-scope debugfs entries

Several MTD devices are using debugfs entries created in the root.
This commit provides the means for a standardized subtree, creating
one "mtd" entry at root, and one entry per device inside it, named
after the device.
The tree is registered in add_mtd_device, and released in
del_mtd_device.
Devices docg3, mtdswap and nandsim were updated to use this subtree
instead of custom ones, and their entries were prefixed with the
drivers' names.

Subject: clk: qoriq: add clock configuration for ls1088a soc

Clock on ls1088a chip takes primary clocking input from the external
SYSCLK signal. The SYSCLK input (frequency) is multiplied using
multiple phase locked loops (PLL) to create a variety of frequencies
which can then be passed to a variety of internal logic, including
cores and peripheral IP modules.

Subject: device property: Get rid of struct fwnode_handle type field

Instead of relying on the struct fwnode_handle type field, define
fwnode_operations structs for all separate types of fwnodes. To find out
the type, compare to the ops field to relevant ops structs.

This change has two benefits:

1. it avoids adding the type field to each and every instance of struct
fwnode_handle, thus saving memory and

2. makes the ops field the single factor that defines both the types of
the fwnode as well as defines the implementation of its operations,
decreasing the possibility of bugs when developing code dealing with
fwnode internals.

Subject: ACPI: Prepare for constifying acpi_get_next_subnode() fwnode argument

Make local variables const (head) or add new variables; adev was used for
two purposes: to refer the root device node and its children. The two
purposes are separated by this patch.

This is preparation for making fwnode arguments const for fwnode ops.
Don't constify the argument itself quite yet as this is used as a callback
function.

Subject: device property: Introduce fwnode_property_get_reference_args

The new fwnode_property_get_reference_args() interface amends the fwnode
property API with the functionality of both of_parse_phandle_with_args()
and __acpi_node_get_property_reference().

The semantics is slightly different: the cells property is ignored on ACPI
as the number of arguments can be explicitly obtained from the firmware
interface.

Subject: clk: Convert to using %pOF instead of full_name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

From 501c574f4e3a59d30b3b915d843811485e3e702d Mon Sep 17 00:00:00 2001

Subject: cpufreq: mediatek: Add support of cpufreq to MT2701/MT7623 SoC

MT2701/MT7623 is a 32-bit ARMv7 based quad-core (4 * Cortex-A7) with
single cluster and this hardware is also compatible with the existing
driver through enabling CPU frequency feature with operating-points-v2
bindings. Also, this driver actually supports all MediaTek SoCs, the
Kconfig menu entry and file name itself should be updated with more
generic name to drop "MT8173"

Subject: cpufreq: dt: Don't use generic platdev driver for tango

On tango platforms, firmware configures the CPU clock, and Linux is
then only allowed to use the cpu_clk_divider to change the frequency.
Build the OPP table dynamically at init, in order to support whatever
firmware throws at us.

Subject: cpufreq: governor: Drop min_sampling_rate

The cpufreq core and governors aren't supposed to set a limit on how
fast we want to try changing the frequency. This is currently done for
the legacy governors with help of min_sampling_rate.

At worst, we may end up setting the sampling rate to a value lower than
the rate at which frequency can be changed and then one of the CPUs in
the policy will be only changing frequency for ever.

But that is something for the user to decide and there is no need to
have special handling for such cases in the core. Leave it for the user
to figure out.

Subject: cpufreq: Use transition_delay_us for legacy governors as well

The policy->transition_delay_us field is used only by the schedutil
governor currently, and this field describes how fast the driver wants
the cpufreq governor to change CPUs frequency. It should rather be a
common thing across all governors, as it doesn't have any schedutil
dependency here.

Create a new helper cpufreq_policy_transition_delay_us() to get the
transition delay across all governors.

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
Date: Wed, 19 Jul 2017 02:38:44 +0200
Subject: PM / sleep: Do not print debug messages by default

Debug messages from the system suspend/hibernation infrastructure can
fill up the entire kernel log buffer in some cases and anyway they
are only useful for debugging.  They depend on CONFIG_PM_DEBUG, but
that is set as a rule as some generally useful diagnostic facilities
depend on it too.

For this reason, avoid printing those messages by default, but make
it possible to turn them on as needed with the help of a new sysfs
attribute under /sys/power/.

Subject: driver core: emit uevents when device is bound to a driver

There are certain touch controllers that may come up in either normal
(application) or boot mode, depending on whether firmware/configuration is
corrupted when they are powered on. In boot mode the kernel does not create
input device instance (because it does not necessarily know the
characteristics of the input device in question).

Another number of controllers does not store firmware in a non-volatile
memory, and they similarly need to have firmware loaded before input device
instance is created. There are also other types of devices with similar
behavior.

There is a desire to be able to trigger firmware loading via udev, but it
has to happen only when driver is bound to a physical device (i2c or spi).
These udev actions can not use ADD events, as those happen too early, so we
are introducing BIND and UNBIND events that are emitted at the right
moment.

Also, many drivers create additional driver-specific device attributes
when binding to the device, to provide userspace with additional controls.
The new events allow userspace to adjust these driver-specific attributes
without worrying that they are not there yet.

Many drivers create additional driver-specific device attributes when

export these helpers.

Subject: driver core: add devm_device_add_group() and friends

Many drivers create additional driver-specific device attributes when
binding to the device, and providing managed version of
device_create_group() will simplify unbinding and error handling in probe
path for such drivers.

Without managed version driver writers either have to mix manual and
managed resources, which is prone to errors, or open-code this function by
providing a wrapper to device_add_group() and use it with devm_add_action()
or devm_add_action_or_reset().

Subject: USB: misc: remove unneeded MODULE_VERSION() usage

MODULE_VERSION is useless for in-kernel drivers, so just remove all
usage of it in the USB misc drivers.  Along with this, some
DRIVER_VERSION macros were removed as they are also pointless.

Subject: USB: atm: remove unneeded MODULE_VERSION() usage

MODULE_VERSION is useless for in-kernel drivers, so just remove all
usage of it in the USB ATM drivers.  Along with this, some
DRIVER_VERSION macros were removed as they are also pointless.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: usb: core: hub: controller driver name may be NULL

The controller driver may be NULL if the controller device
is the middle device between platform device and roothub.
This middle device may not need a device driver due to all
hardware control can be at platform device driver, this
platform device is usually a dual-role USB controller device.

The benefit of using this middle device is we can keep both
controller device's private data (known as struct usb_hcd)
for USB core use, and platform device's private data for
platform driver use.

Subject: iio: chemical: ccs811: Add support for AMS CCS811 VOC sensor

Add support for CCS811 VOC sensor. This patch adds support
for reading current and voltage across the sensor and TVOC
and equivalent CO2 values.

Scale and offset values have been computed according to datasheet:
    - For current: raw value is in microamps
        => 0.001 scale to convert to milliamps
    - For voltage: 1.65V = 1023, therefore 1650mV = 1023
        => 1650.0/1023 = 1.612903 scale to convert to millivolts
    - For eCO2: raw value range is from 400ppm to 8192ppm.
        => (val - 400) * (100 - 0) / (8192 - 400) + 0 =
           (val - 400) * 0.01283367 => offset: -400, scale = 0.012834
           to get a percentage value
    -For TVOC: raw value range is from 0ppb to 1187ppb.
        => (val - 0) * 100 / (1187 - 0) + 0 = val * 0.0842459 =>
            scale = 0.084246 for getting a percentage value

Subject: iio: humidity: hts221: refactor write_with_mask code

Move bit-shift in hts221_write_with_mask() instead of coding
the shift depth in the configured value. That change will be necessary
to fix an issue in device power-down procedure.
Simplify hts221_avg_list table management

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: IB/ipoib: Fix race between light events and interface restart

A potential race between light_event and interface restart
may attach multicast group to an already attached QP.

Scenario:
light_event flow goes through ipoib_mcast_dev_flush function,
if a context switch occurs before calling ipoib_mcast_remove_list,
then we may face a situation where the broadcast of the priv is null
and the corresponding QP is not detached yet.
If an "interface restart" runs during the previous context switch,
the following scenario occurs:
When the device goes up, ipoib_ib_dev_up function will be called,
it will send a new registration request to the broadcast group and then
attach the group to the QP that was not detached before.

     IPOIB_FLUSH_LIGHT                                          INTERFACE RESTART

Subject: IB/ipoib: Use cancel_delayed_work_sync when needed

The work mcast_task can re-queue itself, so instead of doing
cancel && flush_workqueue, that still can leave a queued task
on the air, use cancel_delayed_work_sync.

Also, no need to use lock over the cancel, the original lock was
due to bit assignment setting (IPOIB_MCAST_RUN) that is not in use
anymore.

Subject: IB/ipoib: Make sure no in-flight joins while leaving that mcast

While cleaning neighs and there is a send-only mcast neigh, the driver
should wait to finish its join process before trying to remove it.

Without this patch, we will see messages like: "ipoib_mcast_leave on an
in-flight join" and unexpected results in the join_complete.

redundant all "else" cases.

The functions are called during the flow are returning "result < 0", in

The commit ebc9ca43e1d5 ("IB/core: Allow QP state transition from reset to error")
allowed transition from Reset to Error state for the QPs. This behavior
doesn't follow the IBTA specification 1.3, which in 10.3.1 QUEUE PAIR AND
EE CONTEXT STATES section.

The quote from the spec:
"An error can be forced from any state, except Reset, with
the Modify QP/EE Verb."

Subject: IB/ipoib: Notify on modify QP failure only when relevant

Modify QP can fail and it can be acceptable, like when moving from RST to
ERR state, all the rest are not acceptable and a message to the log
should be printed.

The current code prints on all failures and many messages like:
"Failed to modify QP to ERROR state" appear, even when supported by the
state machine of the QP object.

Subject: vfio: ccw: fix bad ptr math for TIC cda translation

When we are translating channel data addresses from guest to host
address space for TIC instructions we are getting incorrect
addresses because of a pointer arithmetic error.

We currently calculate the offset of the TIC's cda from the start
of the channel program chain (ccw->cda - ccw_head). We then add
that to the address of the ccw chain in host memory (iter->ch_ccw).
The problem is that iter->ch_ccw is a pointer to struct ccw1 so
when we increment it we are actually incrementing by the size of
struct ccw1 which is 8 bytes. The intent was to increment by
n-bytes, not n*8.

The fix: cast iter->ch_ccw to char* so it will be incremented by
n*1.

Subject: power: supply: act8945a_charger: fix of_irq_get() error check

of_irq_get() may return any negative error number as well as 0 on failure,
while the driver only checks for -EPROBE_DEFER, blithely continuing with
the call to devm_request_irq() -- that function expects *unsigned int*,
so would probably fail anyway when a large IRQ number resulting from a
conversion of a negative error number is passed to it... This, however,
is incorrect behavior -- error number is not IRQ number.

Check for 'irq <= 0' instead and return -ENXIO from probe if of_irq_get()
returned 0.

Subject: power: supply: constify attribute_group structures.

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   2673	    400	      0	   3073	    c01	power/supply/pcf50633-charger.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   2737	    336	      0	   3073	    bed	power/supply/pcf50633-charger.o

Subject: power: supply: Add support for MAX1721x standalone fuel gauge

The MAX17211 monitor a single cell pack. The MAX17215 monitor and
balance a 2S or 3S pack or monitor a multiple-series cell pack.
Both device use 1-Wire interfce.

From d41861942fc55c14b6280d9568a0d0112037f065 Mon Sep 17 00:00:00 2001
From: Yuval Shaia <yuval.shaia@oracle.com>
Date: Wed, 14 Jun 2017 23:13:34 +0300
Subject: IB/core: Add generic function to extract IB speed from netdev

Logic of retrieving netdev speed from net_device and translating it to
IB speed is implemented in rxe, in usnic and in bnxt drivers.

Define new function which merges all.

Subject: RDMA: Remove useless MODULE_VERSION

All modules in drivers/infiniband defined and used MODULE_VERSION, which
was pointless because the kernel version describes their state more accurate
then those arbitrary numbers.

Subject: RDMA/bnxt_re: Add vlan tag for untagged RoCE traffic when PFC is
 configured

Current implementation does not program vlan header insertion
in RoCE packet if no vlan is configured. Firmware does not add
prority when there is no vlan tag in the packet. Modify the code
to insert vlan header when PFC is enabled on the interface.

Subject: RDMA/bnxt_re: Allow posting when QPs are in error

This  patch allows driver to post send and receive
requests on QPs which are in  error state.

Instead of flushing the QP in the context of polling
error CQEs, the QPs will be added to a flush list
maintained per CQ. QP state is moved to error.
QP is added to flush list if the user moves it
to error state using modify_qp also. After polling the HW
CQ in poll_cq routine, this flush list is traversed
and driver completes work requests on each QP in the flush
list, till the budget expires. The QP is moved out of
flush list during QP destroy or during modify_QP to RESET.

When ULPs post Work Requests while QP is in error state,
driver will store the ULP data and then increment the
QP producer s/w index, without ringing doorbell. It then
schedules a worker to invoke the CQ handler since the
interrupts wont be generated from the HW for this request.

From c85023e153e3824661d07307138fdeff41f6d86a Mon Sep 17 00:00:00 2001
From: Huy Nguyen <huyn@mellanox.com>

Subject: IB/mlx5: Add raw ethernet local loopback support

Currently, unicast/multicast loopback raw ethernet
(non-RDMA) packets are sent back to the vport.
A unicast loopback packet is the packet with destination
MAC address the same as the source MAC address.
For multicast, the destination MAC address is in the
vport's multicast filter list.

Moreover, the local loopback is not needed if
there is one or none user space context.

After this patch, the raw ethernet unicast and multicast
local loopback are disabled by default. When there is more
than one user space context, the local loopback is enabled.

Note that when local loopback is disabled, raw ethernet
packets are not looped back to the vport and are forwarded
to the next routing level (eswitch, or multihost switch,
or out to the wire depending on the configuration).

Subject: IB/mlx5: Change logic for dispatching IB events for port state

The old logic ignored link state. This led to missing IB events like
when link goes down on the switch while admin state is up or to redundant
events like when admin state goes up while link is down.
To fix that, probe the port state on NETDEV events and compare to last
known state to decide if IB events needs to be dispatched.

Subject: IB/mlx5: Add debug control parameters for congestion control

This patch adds debug control parameters for congestion control which
can be read or written through debugfs. They are for reaction point and
notification point nodes.

These control parameters are as below:

Subject: IB/mlx5: Restore IB guid/policy for virtual functions

When a user sets port_guid, node_guid or policy of an IB virtual
function, save this information in "struct mlx5_vf_context".

This information will be restored later when pci_resume is called.
To make sure this works, one can use aer-inject to generate PCI
errors on mlx5 devices and verify if relevant fields are restored
after PCI resume.

Subject: net/mlx5: Introduce set delay drop command

Add support to SET_DELAY_DROP command.

This command will be used in downstream patches for delay packet drop.
The timeout value should be indicated by delay_drop_timeout field.
Packet processing will be delayed till timeout value passed or until
more WQEs are posted.

Setting this value to 0 disables the feature.

Subject: net/mlx5: Introduce general notification event

When delay drop timeout is expired, the firmware raises
general notification event of DELAY_DROP_TIMEOUT subtype.
In addition the feature is disable so the driver have to
reactivate the timeout.

Subject: IB/mlx5: Add support to dropless RQ

RQs that were configured for "delay drop" will prevent packet drops
when their WQEs are depleted.
Marking an RQ to be drop-less is done by setting delay_drop_en in RQ
context using CREATE_RQ command.

Since this feature is globally activated/deactivated by using the
SET_DELAY_DROP command on all the marked RQs, we activated/deactivated
it according to the number of RQs with 'delay_drop' enabled.

When timeout is expired, then the feature is deactivated. Therefore
the driver handles the delay drop timeout event and reactivate it.

Subject: IB/mlx5: Add delay drop configuration and statistics

Add debugfs interface for monitor the number of delay drop timeout
events and the number of existing dropless RQs in the system.

In addition add debugfs interface for configuring the global timeout value
which is used in the SET_DELAY_DROP command.

Subject: IB/core: Fix the validations of a multicast LID in attach or detach
 operations

RoCE Annex (A16.9.10/11) declares that during attach (detach) QP to a
multicast group, if the QP is associated with a RoCE port, the
multicast group MLID is unused and is ignored.

During attach or detach multicast, when the QP is associated with a
port, it is enough to check the port's link layer and validate the
LID only if it is Infiniband. Otherwise, avoid validating the
multicast LID.

Fixes: 8561eae60ff9 ("IB/core: For multicast functions, verify that LIDs are multicast LIDs")

Subject: IB/core: Set RoCEv2 MGID according to spec

RoCEv2 Annex states that for RoCEv2 over IPv4, the corresponding
IPv4 address is encoded into the GID according to the following rule:
GID= :ffff:<IPv4 address>

Remove the 0xff0e prefix for RoCEv2 packets with IPv4 and leave it
zeroed and change rdma_is_multicast_addr() to consider the new logic.

When creating address handle from multicast GID, set MAC according to
the appropriate formula instead of searching for it in the GID table:
- For IPv4 multicast GID use ip_eth_mc_map().
- For IPv6 multicast GID use ipv6_eth_mc_map().

Subject: IB/uverbs: Enable QP creation with a given source QP number

Enable QP creation with a given source QP number, the created QP will
use the source QPN as its wire QP number.

To create such a QP, root privileges (i.e. CAP_NET_RAW) are required
from the user application.

This comes as a pre-patch for downstream patches in this series to
allow user space applications to accelerate traffic which is typically
handled by IPoIB ULP.

Subject: IB/mlx5: Add support for QP with a given source QPN

Allow user space applications to accelerate send and receive
traffic which is typically handled by IPoIB ULP by creating
a UD QP with a given source QPN of the IPoIB UD QP.

UD QP with a given source QPN should basically be similar to
RAW QP from point of view of its created resources.

However,
- Its TIS should point to the source QPN.
- Modify can be done only on its state as the transport attributes
  are managed by its source QP.

This patch manages below:
- Creating/destroying/modifying UD QP with a given source QPN.

Subject: IB/mlx5: Add multicast flow steering support for underlay QP

In order to add multicast flow steering support, there is need
to block the attaching of mcg flow for underlay QP, recognize
multicast IB_FLOW_SPEC_IPV4 based on its IP and enable
creating/destroying flow for IB layer.

Subject: IB/mlx5: Fix cached MR allocation flow

When we have a miss in one order of the mkey cache, we try to get
an mkey from a higher order.

We still need to check that the higher order can be used with UMR
before using it. Otherwise, we will get an mkey with 0 entries and
the post send operation that is used to fill it will complete with
the following error:

mlx5_0:dump_cqe:275:(pid 0): dump error cqe

Subject: IB/mlx4: Add inline-receive support

When inline-receive is enabled, the HCA may write received
data into the receive WQE.

Inline-receive is enabled by setting its matching bit in
the QP context and each single-packet message with payload
not exceeding the receive WQE size will be delivered to
the WQE.

The completion report will indicate that the payload was placed to the WQE.

It includes:
1) Return maximum supported size of inline-receive by the hardware
in query_device vendor's data part.
2) Enable the feature when requested by the vendor data input.

Subject: (IB, net)/mlx4: Add resource utilization support

Adding visibility of resource usage of QPs, CQs and counters used by
virtual functions. This feature will be used to give the PF administrator
more data while debugging VF status. Usage info was added to ALLOC_RES
command, to notify the PF if the resource which is being reserved or
allocated for the VF will be used by kernel driver or by user verbs.

Updated reservation and allocation functions of QP, CQ and counter with
additional usage parameter.

From 400b1ebcfe31279895f1baa8ecaa390d9a4a0eef Mon Sep 17 00:00:00 2001
From: Guy Levi <guyle@mellanox.com>
Date: Tue, 4 Jul 2017 16:24:24 +0300
Subject: IB/mlx4: Add support for WQ related verbs

Support create/modify/destroy WQ related verbs.

The base IB object to enable RSS functionality is a WQ (i.e. ib_wq).
This patch implements the related WQ verbs as of create, modify and
destroy.

In downstream patches the WQ will be used as part of an indirection
table (i.e. ib_rwq_ind_table) to enable RSS QP creation.

Notes:
ConnectX-3 hardware requires consecutive WQNs list as receive descriptor
queues for the RSS QP. Hence, the driver manages consecutive ranges lists
per context which the user must respect.
Destroying the WQ does not return its WQN back to its range for
reusing. However, destroying all WQs from the same range releases the
range and in turn releases its WQNs for reusing.

Since the WQ object is not a natural object in the hardware, the driver
implements the WQ by the hardware QP.

As such, the WQ inherits its port from its RSS QP parent upon its
RST->INIT transition and by that time its state is applied to the
hardware.

From b8d46ca035060e70f5f0da849d86720752d5aa17 Mon Sep 17 00:00:00 2001
From: Guy Levi <guyle@mellanox.com>
Date: Tue, 4 Jul 2017 16:24:25 +0300
Subject: IB/mlx4: Add support for WQ indirection table related verbs

To enable RSS functionality the IB indirection table object (i.e.
ib_rwq_ind_table) should be used.
This patch implements the related verbs as of create and destroy an
indirection table.

In downstream patches the indirection table will be used as part of RSS
QP creation.

Subject: IB/mlx4: Add support for RSS QP

Add support to work with a RSS QP by using an indirection table object
upon QP creation. Other related QP verbs (e.g. modify/destroy/query) were
updated as well for that QP mode.

Notes:
- The RX hash properties are supplied as driver private data.
- The RSS QP port is used on the associated WQs in its indirection
  table. Applying different ports during WQ life time is not allowed.
- The expected RSS QP flow is: create, modify(RST->INIT),
  modify(RST->RTR), destroy.

Subject: of_pci: use of_property_read_u32_array()

of_pci_get_devfn() and of_pci_parse_bus_range() somehow didn't use
of_property_read_u32_array() though it was long available, basically
open-coding it.  Using the modern DT API saves several bytes and
also adds some prop sanity checks as a bonus...

Currently we are calling usb_submit_urb directly to submit deferred tx
urbs after unanchor them.

So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak:
unreferenced object 0xffffffc0ce0fa400 (size 256):

Put those urbs in tx_anchor to avoid the leak, and also fix the error

Pack headroom into ctx - this way when we get a buffer we can figure out
the actual headroom that was allocated for the buffer. Will be helpful
to optimize switching between XDP and non-XDP modes which have different
headroom requirements.

Subject: virtio-net: do not reset during XDP set

We currently reset the device during XDP set, the main reason is
that we allocate more headroom with XDP (for header adjustment).

This works but causes network downtime for users.

Previous patches encoded the headroom in the buffer context,
this makes it possible to detect the case where a buffer
with headroom insufficient for XDP is added to the queue and
XDP is enabled afterwards.

Upon detection, we handle this case by copying the packet
(slow, but it's a temporary condition).

Subject: virtio-net: switch off offloads on demand if possible on XDP set

Current XDP implementation wants guest offloads feature to be disabled
on device. This is inconvenient and means guest can't benefit from
offloads if XDP is not used. This patch tries to address this
limitation by disabling the offloads on demand through control guest
offloads. Guest offloads will be disabled and enabled on demand on XDP
set.

Subject: net: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: ACPI / PMIC: xpower: Do pinswitch magic when reading GPADC

Testing has shown that the TS-pin's bias-current needs to be disabled
when reading the GPIO0 pin in GPADC mode.

It seems that there is only 1 bias current source and to be able to use it
for the GPIO0 pin in GPADC mode it must be temporarily turned off for the
TS pin, but the datasheet does not mention this.

This commit adds the necessary writes to turn the TS pin BIAS current
off before and back on after reading the GPADC. This fixes the GPADC
always returning a reading of 0.

Subject: geneve: add rtnl changelink support

This patch adds changelink rtnl operation support for geneve devices
and the code changes involve:

  - added geneve_quiesce() which quiesces the geneve device data path
    for both TX and RX. This lets us perform the changelink operation
    atomically w.r.t data path. Also added geneve_unquiesce() to
    reverse the operation of geneve_quiesce().

  - refactor geneve_newlink into geneve_nl2info to be used by both
    geneve_newlink and geneve_changelink

  - geneve_nl2info takes a changelink boolean argument to isolate
    changelink checks.

  - Allow changing only a few attributes (ttl, tos, and remote tunnel
    endpoint IP address (within the same address family)):
    - return -EOPNOTSUPP for attributes that cannot be changed for
      now. Incremental patches can make the non-supported one
      available in the future if needed.

Subject: geneve/vxlan: offload ports on register/unregister events

This improves consistency of handling when moving a netdev to another
netns. Most drivers currently do a full reset when the device goes up,
so that will flush the offload state anyway.

Subject: PM / Domains: Extend generic power domain debugfs

This patch extends the existing generic power domain debugfs.
Changes involve the following
- Introduce a unique debugfs entry for each generic power domain with the
  following attributes
	- current_state - Displays current state of the domain.
	- devices - Displays the devices associated with this domain.
	- sub_domains - Displays the sub power domains.
	- active_time - Displays the time the domain was in active state
			in ms.
	- total_idle_time - Displays the time the domain was in any of the idle
			states in ms.
	- idle_states - Displays the various idle states and the time
			spent in each idle state in ms.

Subject: PM / core: Split dpm_suspend_noirq() and dpm_resume_noirq()

Put the device interrupts disabling and enabling as well as
cpuidle_pause() and cpuidle_resume() called during the "noirq"
stages of system suspend into separate functions to allow the
core suspend-to-idle code to be optimized (later).

The only functional difference this makes is that debug facilities
and diagnostic tools will not include the above operations into the
"noirq" device suspend/resume duration measurements.

Subject: PM / core: Add error argument to dpm_show_time()

Make the core device suspend/resume code also call dpm_show_time()
on failures and add an error argument to this function so that the
message printed by it can reflect the success or failure condition.

This makes the debug messages in question look less confusing in
the failing cases.

Subject: PM / sleep: Check pm_wakeup_pending() in __device_suspend_noirq()

Restore the pm_wakeup_pending() check in __device_suspend_noirq()
removed by commit eed4d47efe95 (ACPI / sleep: Ignore spurious SCI
wakeups from suspend-to-idle) as that allows the function to return
earlier if there's a wakeup event pending already (so that it may
spend less time on carrying out operations that will be reversed
shortly anyway) and rework the main suspend-to-idle loop to take
that optimization into account.

Subject: mlxsw: spectrum_router: Don't batch neighbour deletion

Current firmware supported by the driver doesn't support batch deletion
of IPv6 neighbours on a given router interface (RIF).

Until a new version that supports this functionality is made available,
delete neighbours one by one.

Subject: of_mdio: kill useless variable in of_phy_register_fixed_link()

of_phy_register_fixed_link() declares the 'err' variable to hold the result
of of_property_read_string() but only uses it once after that, while that
function can be called directly from the *if* statement...

Remove that variable and move/regroup 'link_gpio' and 'len' variables in
order to sort the declarations in the reverse Xmas tree order -- to please
DaveM. ;-)

Subject: mtd: mtdswap: remove unused variables 'dev' and 'gd'

This was changed recently (commit e8e3edb95ce6 ("mtd: create per-device
and module-scope debugfs entries")) and some compilers are complaining:

   drivers//mtd/mtdswap.c: In function 'mtdswap_add_debugfs':
>> drivers//mtd/mtdswap.c:1317: warning: unused variable 'dev'

And once we kill 'dev', 'gd' is also unused.

Subject: mlxsw: spectrum_router: Fix build when IPv6 isn't enabled

When IPv6 isn't enabled the following error is generated:

ERROR: "nd_tbl" [drivers/net/ethernet/mellanox/mlxsw/mlxsw_spectrum.ko]
undefined!

Fix it by replacing 'arp_tbl' and 'nd_tbl' with 'tbl->family' wherever
possible and reference 'nd_tbl' only when IPV6 is enabled.

Fixes: d5eb89cf68d6 ("mlxsw: spectrum_router: Reflect IPv6 neighbours to the device")

Subject: bnxt_en: Add bnxt_get_num_stats() to centrally get the number of
 ethtool stats.

Instead of duplicating the logic multiple times.  Also, it is unnecessary
to zero the buffer in .get_ethtool_stats() because it is already zeroed
by the caller.

For debugging purpose, it is sometimes useful to disable periodic
port statistics updates, so that the firmware logs will not be
filled with statistics update messages.

Subject: bnxt_en: Report firmware DCBX agent.

Report DCB_CAP_DCBX_LLD_MANAGED only if the firmware DCBX agent is enabled
and running for PF or VF.  Otherwise, if both LLDP and DCBX agents are
disabled in firmware, we report DCB_CAP_DCBX_LLD_HOST and allow host
IEEE DCB settings.  This patch refines the current logic in the driver.

Subject: bnxt_en: add support to enable VF-representors

This patch is a part of a patch-set that introduces support for
VF-reps in the bnxt_en driver. The driver registers eswitch mode
get/set methods with the devlink interface that allow a user to
enable SRIOV switchdev mode. When enabled, the driver registers
a VF-rep netdev object for each VF with the stack. This can
essentially bring the VFs unders the management perview of the
hypervisor and applications such as OVS.

The next patch in the series, adds the RX/TX routines and a slim
netdev implementation for the VF-reps.

From ee5c7fb3404724b9e25fe24c81fbcda60f3f2659 Mon Sep 17 00:00:00 2001
From: Sathya Perla <sathya.perla@broadcom.com>

Subject: bnxt_en: add vf-rep RX/TX and netdev implementation

This patch introduces the RX/TX and a simple netdev implementation
for VF-reps. The VF-reps use the RX/TX rings of the PF. For each VF-rep
the PF driver issues a VFR_ALLOC FW cmd that returns "cfa_code"
and "cfa_action" values. The FW sets up the filter tables in such
a way that VF traffic by default (in absence of other rules)
gets punted to the parent PF. The cfa_code value in the RX-compl
informs the driver of the source VF. For traffic being transmitted
from the VF-rep, the TX BD is tagged with a cfa_action value that
informs the HW to punt it to the corresponding VF.

From: Sathya Perla <sathya.perla@broadcom.com>

Subject: bnxt_en: add support for port_attr_get and and get_phys_port_name

This patch adds support for the switchdev_port_attr_get() and
ndo_get_phys_port_name() methods for the PF and the VF-reps.
Using this support a user application can deduce that the PF
(when in the ESWITCH_SWDEV mode) and it's VF-reps form a switch.

Subject: netvsc: Remove redundant use of ipv6_hdr()

This condition already uses an object of type ipv6hdr in the line above.
Use the object directly instead of calling ipv6_hdr

Subject: ibmvnic: Check for transport event on driver resume

On resume, the ibmvnic driver will fail to resume normal operation.
The main crq gets closed on suspend by the vnic server and doesn't get
reopened again as the interrupt for the transport event that would reset
the main crq comes in after the driver has been suspended.

This patch resolves the issue by removing the calls to kick the receive
interrupts handlers and instead directly invoking the main crq interrupt
handler. This will ensure that we see the transport event necessary to
properly resume the driver.

Subject: power: supply: sbs-battery: Add delay when changing capacity mode bit

At least with the Inspired Energy compatible batteries a delay is required
after setting the capacity mode bit from amp to watts or the reverse.
Setting the bit and then immediately pooling the status register results
in an unknown error being returned in the register. Add the delay results
in and ok status being return. This was also seen when reading the charge
and energy registers where the wrong value was returned for the requested
mode.

Subject: power: supply: ltc2941-battery-gauge: Prepare for LTC2942 and LTC2944

In order to support LTC2942 which has temperature registers
at different offsets than LTC2943 use following register naming
scheme (prefixes):
- LTC294X_ common registers
- LTC2942_ chips specific registers
- LTC2943_ specific registers

LTC2944 is compatible with LTC2943 but uses different constants
to compute voltage and current, so replace num_regs misused
for device indentification with real device id to discriminate
between those two.

There are no functional changes.

Subject: pwm: pca9685: clarify pca9685_set_sleep_mode() interface.

The function
static void pca9685_set_sleep_mode(struct pca9685 *pca, int sleep)
takes the chip in and out of sleep mode, depending on the value of
sleep, which is interpreted as a boolean.

To clarify that 'int sleep' is a boolean and not a sleep delay,
change the function interface to:
static void pca9685_set_sleep_mode(struct pca9685 *pca, bool enable)

Subject: power: supply: bq27xxx: move platform driver code into
 bq27xxx_battery_hdq.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the BQ27xxx driver was originally written the w1 subsystem only
allowed device drivers for w1 attached devices to live in the w1
subsystem. Kernel driver subsystems expect that the driver for a device
live in the directory of the subsystem for which it implements
functionality, not in the directory of the bus that it is attached. To
work around this, the BQ27xxx driver was implemented as a platform device
driver and the interface driver would instantiate this device from within
the w1 directory, then pass a w1 read callback as platform data.

As we can now have the w1 interface driver in the power/supply directory
(like we do already with the i2c interface driver) we can remove this
middle-layer platform driver.

Subject: platform/x86: peaq-wmi: silence a static checker warning

There is a harmless static checker warning here that unsigned values are
always >= 0.  The code looks like:

	if (peaq_ignore_events_counter && --peaq_ignore_events_counter >= 0)

The first part of the condition ensures that we never wrap around so the
code works as intended.  I've tweaked it slightly to avoid the warning.

Subject: platform/x86: msi-wmi: remove unnecessary static in msi_wmi_notify()

Remove unnecessary static on local variable _key_. Such variable is
initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces
the object file size.

This issue was detected using Coccinelle and the following semantic patch:
https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci

In the following log you can see a significant difference in the object
file size. Also, there is a significant difference in the bss segment.
This log is the output of the size command, before and after the code
change:

Subject: platform/x86: alienware-wmi: fix format string overflow warning

gcc points out a possible format string overflow for a large value of 'zone':

drivers/platform/x86/alienware-wmi.c: In function 'alienware_wmi_init':
drivers/platform/x86/alienware-wmi.c:461:24: error: '%02X' directive writing between 2 and 8 bytes into a region of size 6 [-Werror=format-overflow=]
   sprintf(buffer, "zone%02X", i);
                        ^~~~
drivers/platform/x86/alienware-wmi.c:461:19: note: directive argument in the range [0, 2147483646]
   sprintf(buffer, "zone%02X", i);
                   ^~~~~~~~~~
drivers/platform/x86/alienware-wmi.c:461:3: note: 'sprintf' output between 7 and 13 bytes into a destination of size 10

This replaces the 'int' variable with an 'u8' to make sure
it always fits, renaming the variable to 'zone' for clarity.

Unfortunately, gcc-7.1.1 still warns about it with that change, which
seems to be unintended by the gcc developers. I have opened a bug
against gcc with a reduced test case. As a workaround, I also
change the format string to use "%02hhX", which shuts up the
warning in that version.

+Cirrus Logic EP93xx ADC driver.
+
+1. Overview
+
+The driver is intended to work on both low-end (EP9301, EP9302) devices with
+5-channel ADC and high-end (EP9307, EP9312, EP9315) devices with 10-channel
+touchscreen/ADC module.
+
+2. Channel numbering
+
+Numbering scheme for channels 0..4 is defined in EP9301 and EP9302 datasheets.
+EP9307, EP9312 and EP9312 have 3 channels more (total 8), but the numbering is
+not defined. So the last three are numbered randomly, let's say.
+
+Assuming ep93xx_adc is IIO device0, you'd find the following entries under
+/sys/bus/iio/devices/iio:device0/:
+
+  +-----------------+---------------+
+  | sysfs entry     | ball/pin name |
+  +-----------------+---------------+
+  | in_voltage0_raw | YM            |
+  | in_voltage1_raw | SXP           |
+  | in_voltage2_raw | SXM           |
+  | in_voltage3_raw | SYP           |
+  | in_voltage4_raw | SYM           |
+  | in_voltage5_raw | XP            |
+  | in_voltage6_raw | XM            |

Subject: nfp: set config bit (ifup/ifdown) on netdev open/close

When a netdev (PF netdev or representor) is opened or closed, set the
physical port config bit appropriately - which powers UP/DOWN the PHY
module for the physical interface.

The PHY is powered first in the HW/FW configuration step when opening
the netdev and again last in the HW/FW configuration step when closing
the netdev.

This is only applicable when there is a physical port associated with
the netdev and if the NSP support this. Otherwise we silently ignore
this step.

The 'nfp_eth_set_configured' can actually return positive values -
updated the function documentation appropriately.

Subject: bnxt_en: fix switchdev port naming for external-port-rep and vf-reps

Fix the phys_port_name for the external physical port to be in
"pA" format and that of VF-rep to be in "pCvfD" format as
suggested by Jakub Kicinski.

Copy the approach taken by gfx8, which simplifies the code, and set the
instance index properly. The latter is required for debugging, e.g. for
reading wave status by UMR.

Allows gdb to access contents of user mode mapped BOs. System memory
is handled by TTM using kmap. Other memory pools require a new driver
callback in ttm_bo_driver.

v2:
* kmap only one page at a time
* swap in BO if needed
* make driver callback more generic to handle private memory pools
* document callback return value
* WARN_ON -> WARN_ON_ONCE

Subject: drm/amdgpu/gmc8: SRIOV need to program fb location

SRIOV won't do vbios post in guest OS, and the mmMC_VM_FB_LOCATION
is pf and vf copy, so still need to program fb location for SRIOV.

v2: No need to stop mc, and update gmc_v8_0_vram_gtt_location as well.

v3: New line after the stack variables

BUG: SWDEV-126629

Subject: drm/amdgpu: correct clock info for SRIOV

Currently, get clock info from default clk of pm if dpm is disable.
Buf SRIOV doesn't support dpm and pm, can't get anything from pm.
Only get clock info only from default clk of amdgpu for SRIOV.

And driver get pm default clk also from amdgpu default clk and never
be changed by others. So use amdgpu default clk value for SRIOV
and non-dpm cases.

The fragment bits work differently for Vega10 compared to previous generations.

Increase the fragment size to 2MB for now to better handle that.

v2: handle the hardware setup as well

Subject: drm/amdgpu: enable huge page handling in the VM v5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The hardware can use huge pages to map 2MB of address space with only one PDE.

v2: few cleanups and rebased
v3: skip PT updates if we are using the PDE
v4: rebased, added support for CPU based updates
v5: fix CPU based updates once more
v6: fix ndw estimation

Subject: drm/radeon: Set depth on low mem to 16 bpp instead of 8 bpp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The radeon driver reduces the framebuffer resolution to 8bpp if a
device with less than 32MB VRAM is found.  This causes the framebuffer
to run in 8 bit paletted mode.  For a text console this is not an
issue as 256 different colors is more than one gets on a VGA text
console.  However this leads to a poor 8bit pseudo-color visual when
running X on fbdev, too, which is quite ugly.

In this patch, we try to give some moderate compromise: limit the
framebuffer bpp to 8 only when VRAM is 8MB or less, and use 16 bpp
otherwise for 32MB or less VRAM.

Remove the error message "[drm:amdgpu_irq_disable_all

For virtual dce, it only use AMDGPU_CRTC_IRQ_VBLANK1 -
AMDGPU_CRTC_IRQ_VBLANK6, and don't use AMDGPU_CRTC_IRQ_VLINE1
- AMDGPU_CRTC_IRQ_VLINE6. And when rmmod amdgpu, it will disable
all interrupts, it will return error when the type of crtc irq
interrupt is AMDGPU_CRTC_IRQ_VLINE1 - AMDGPU_CRTC_IRQ_VLINE6.

VRAM is usually marked write combined, so change ioremap mode from
noncache to write combine for reading vbios from VRAM.

This will reduce cost time of reading vbios from 188ms to 8ms.

Clang warns:

to 'signed char' changes value from 200 to -56
[-Wconstant-conversion]
  client->ps2[1] = 0x60; client->ps2[2] = 3; client->ps2[3] = 200;

As the PS2 data is really a stream of bytes, let's switch to using u8 type
for it, which silences this warning.

Subject: cpufreq: Don't set transition_latency for setpolicy drivers

The transition_latency field isn't used for drivers with ->setpolicy()
callback present and there is no point setting it from the drivers.

Subject: cpufreq: arm_big_little: Make ->get_transition_latency() mandatory

All users of arm_big_little driver are defining it and there is no need
to keep it optional.

Make it mandatory to remove the always true conditional statement.

Subject: cpufreq: Replace "max_transition_latency" with "dynamic_switching"

There is no limitation in the ondemand or conservative governors which
disallow the transition_latency to be greater than 10 ms.

The max_transition_latency field is rather used to disallow automatic
dynamic frequency switching for platforms which didn't wanted these
governors to run.

Replace max_transition_latency with a boolean (dynamic_switching) and
check for transition_latency == CPUFREQ_ETERNAL along with that. This
makes it pretty straight forward to read/understand now.

Subject: cpufreq: Add CPUFREQ_NO_AUTO_DYNAMIC_SWITCHING cpufreq driver flag

The policy->transition_latency field is used for multiple purposes
today and its not straight forward at all. This is how it is used:

A. Set the correct transition_latency value.

B. Set it to CPUFREQ_ETERNAL because:
   1. We don't want automatic dynamic switching (with
      ondemand/conservative) to happen at all.
   2. We don't know the transition latency.

This patch handles the B.1. case in a more readable way. A new flag for
the cpufreq drivers is added to disallow use of cpufreq governors which
have dynamic_switching flag set.

All the current cpufreq drivers which are setting transition_latency
unconditionally to CPUFREQ_ETERNAL are updated to use it. They don't
need to set transition_latency anymore.

There shouldn't be any functional change after this patch.

Subject: cpufreq: Allow dynamic switching with CPUFREQ_ETERNAL latency

With the recent updates, CPUFREQ_ETERNAL is only used by the drivers
which don't know their transition latency but want to use dynamic
switching.

Anyway, the routine cpufreq_policy_transition_delay_us() caps the value
of transition latency to 10 ms now and that can be used safely with such
platforms.

Remove the check from cpufreq_init_governor() and allow dynamic
switching for such configurations as well.

Subject: libnvdimm: Stop using HPAGE_SIZE

Currently libnvdimm uses HPAGE_SIZE as the default alignment for DAX and
PFN devices. HPAGE_SIZE is the default hugetlbfs page size and when
hugetlbfs is disabled it defaults to PAGE_SIZE. Given DAX has more
in common with THP than hugetlbfs we should proably be using
HPAGE_PMD_SIZE, but this is undefined when THP is disabled so lets just
give it a new name.

The other usage of HPAGE_SIZE in libnvdimm is when determining how large
the altmap should be. For the reasons mentioned above it doesn't really
make sense to use HPAGE_SIZE here either. PMD_SIZE seems to be safe to
use in generic code and it happens to match the vmemmap allocation block
on x86 and Power. It's still a hack, but it's a slightly nicer hack.

Subject: ACPI: device property: Switch to use new generic UUID API

There are new types and helpers that are supposed to be used in new code.

As a preparation to get rid of legacy types and API functions do
the conversion here.

Subject: virtio-net: mark PM functions as __maybe_unused

After removing the reset function, the freeze and restore functions
are now unused when CONFIG_PM_SLEEP is disabled:

drivers/net/virtio_net.c:1881:12: error: 'virtnet_restore_up' defined but not used [-Werror=unused-function]
 static int virtnet_restore_up(struct virtio_device *vdev)
drivers/net/virtio_net.c:1859:13: error: 'virtnet_freeze_down' defined but not used [-Werror=unused-function]
 static void virtnet_freeze_down(struct virtio_device *vdev)

A more robust way to do this is to remove the #ifdef around the callers
and instead mark them as __maybe_unused. The compiler will now just
silently drop the unused code.

Subject: iommu/of: Handle PCI aliases properly

When a PCI device has DMA quirks, we need to ensure that an upstream
IOMMU knows about all possible aliases, since the presence of a DMA
quirk does not preclude the device still also emitting transactions
(e.g. MSIs) on its 'real' RID. Similarly, the rules for bridge aliasing
are relatively complex, and some bridges may only take ownership of
transactions under particular transient circumstances, leading again to
multiple RIDs potentially being seen at the IOMMU for the given device.

Take all this into account in the OF code by translating every RID
produced by the alias walk, not just whichever one comes out last.
Happily, this also makes things tidy enough that we can reduce the
number of both total lines of code, and confusing levels of indirection,
by pulling the "iommus"/"iommu-map" parsing helpers back in-line again.

Subject: iommu/vt-d: Don't free parent pagetable of the PTE we're adding

When adding a large scatterlist entry that covers more than the L3
superpage size (1GB) but has an alignment such that we must use L2
superpages (2MB) , we give dma_pte_free_level() a range that causes it
to free the L3 pagetable we're about to populate. We fix this by telling
dma_pte_free_pagetable() about the pagetable level we're about to populate
to prevent freeing it.

For example, mapping a scatterlist with entry lengths 854MB and 1194MB
at IOVA 0xffff80000000 would, when processing the 2MB-aligned second
entry, cause pfn_to_dma_pte() to create a L3 directory to hold L2
superpages for the mapping at IOVA 0xffffc0000000. We would previously
call dma_pte_free_pagetable(domain, 0xffffc0000, 0xfffffffff), which
would free the L3 directory pfn_to_dma_pte() just created for IO PFN
0xffffc0000. Telling dma_pte_free_pagetable() to retain the L3
directories while using L2 superpages avoids the erroneous free.

Based on line 1511: aq_ret = I40_ERR_PARAM; the correct variable to be

updated at line 1602 just before return, so assigning a value to this

Subject: i40e: remove WQ_UNBOUND and the task limit of our workqueue

During certain events such as a CORER, multiple devices will run a work
task to handle some cleanup. This can cause issues due to
a single-threaded workqueue which can mean that a device doesn't cleanup
in time. Prevent this by removing the single-threaded restriction on the
module workqueue. This avoids the need to add more complex yielding
logic in our service task routine. This is also similar to what other
drivers such as fm10k do.

Subject: i40e: Handle admin Q timeout when releasing NVM

There are some rare cases where the release resource call will return an
admin Q timeout. In these cases the code needs to try to release the
resource again until it succeeds or it times out.

Subject: i40e: fix odd formatting and indent

The compiler warned on an oddly indented bit of code, and when
investigating that, noted that the functions themselves had
an odd flow. The if condition was checked, and would exclude
a call to AQ, but then the aq_ret would be checked unconditionally
which just looks really weird, and is likely to cause objections.

Subject: i40e: display correct UDP tunnel type name

The i40e driver attempts to display the UDP tunnel name by doing a check
against the type, where for non-zero types we use "vxlan" and for zero
type we use "geneve". This is not future proof, because if new tunnel
types get added, we'll incorrectly label them. It also depends on the
value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle.

Instead, replace this with a function that can return a constant string
depending on the type. For now we'll use "unknown" for types we don't
know about, and we can expand this in the future if new types get added.

These includes were all being used in the driver, but weren't
being directly included.

Since the current advised method is to directly include anything
that you need, this implements that.

Subject: i40e: report BPF prog id during XDP_QUERY_PROG

Fill the XDP prog_id with the id just like we do in other XDP enabled
drivers such as ixgbe. This is needed so that on dump we can retrieve
the attached program based on the id, and dump BPF insns, opcodes, etc
back to user space. Only XDP driver missing this is currently i40e.

When an administratively set MAC was previously set and should now be
switched back to 00:00:00:00:00:00 the pf_set_mac flag did not get
toggled back to false.
As a result VFs were still treated as if an administratively set MAC was
present.

Extend the driver to make use of iommu_device_register()/unregister()
functions together with iommu_device_set_ops() and iommu_set_fwnode().

These used to be part of the earlier posted 64-bit ARM (r8a7795) series but
it turns out that these days they are required on 32-bit ARM as well.

Subject: iommu: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: drm/qxl: Drop fbdev hwaccel flags

It's not accelarated, just system memory. Note we don't even need to
set the default flag since that's now always 0.

Note that originally qxl had acceleration support, but that was all
ripped out in

Subject: drm/<drivers>: Drop fbdev info flags

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
  the entire panic handling code in our fbdev emulation. We might
  restore kms panic output, but not through the bazillion of legacy
  code layers called fbdev/fbcon, there's just no way to make that
  work safely.

- With the module check change FBINFO_DEFAULT is always 0, so can be
  removed too.

That removes another change to cargo-cult stuff in kms drivers, yay!

Subject: drm/nouveau: Fix error handling in nv50_disp_atomic_commit

Make it more clear that post commit return ret is really return 0,

and add a missing drm_atomic_helper_cleanup_planes when
drm_atomic_helper_wait_for_fences fails.

Subject: drm/atomic: Change drm_atomic_helper_swap_state to return an error.

We want to change swap_state to wait indefinitely, but to do this
swap_state should wait interruptibly. This requires propagating
the error to each driver.

drm_atomic_helper_swap_state() will be changed to interruptible waiting
in the next few commits, so all drivers have to be changed to handling
failure.

Atmel tracks pending commits through dc->commit.pending, so it can
ignore the changes by setting stall = false. We never return failure in
this case, so make failure a BUG_ON.

Subject: drm/msm: Handle drm_atomic_helper_swap_state failure

drm_atomic_helper_swap_state() will be changed to interruptible waiting
in the next few commits, so all drivers have to be changed to handling
failure.

MSM has its own busy tracking, which means the swap_state call can be
done with stall = false, in which case it should never return an error.
Handle failure with BUG_ON for this reason.

Subject: drm/vc4: Handle drm_atomic_helper_swap_state failure

drm_atomic_helper_swap_state() will be changed to interruptible waiting
in the next few commits, so all drivers have to be changed to handling
failure.

VC4 has its own nonblocking modeset tracking through the vc4->async_modeset
semaphore, so it doesn't need to stall in swap_state. Pass stall = false
and BUG_ON when it returns an error. This should never happen for !stall.

Subject: drm/fb-helper: Support deferred setup

FB helper code falls back to a 1024x768 mode if no outputs are connected
or don't report back any modes upon initialization. This can be annoying
because outputs that are added to FB helper later on can't be used with
FB helper if they don't support a matching mode.

The fallback is in place because VGA connectors can happen to report an
unknown connection status even when they are in fact connected.

Some drivers have custom solutions in place to defer FB helper setup
until at least one output is connected. But the logic behind these
solutions is always the same and there is nothing driver-specific about
it, so a better alterative is to fix the FB helper core and add support
for all drivers automatically.

This patch adds support for deferred FB helper setup. It checks all the
connectors for their connection status, and if all of them report to be
disconnected marks the FB helper as needing deferred setup. Whet setup
is deferred, the FB helper core will automatically retry setup after a
hotplug event, and it will keep trying until it succeeds.

v2: Rebase onto my entirely reworked fbdev helper locking. One big
difference is that this version again drops&reacquires the fbdev lock
(which is now fb_helper->lock, but before this patch series it was
mode_config->mutex), because register_framebuffer must be able to
recurse back into fbdev helper code for the initial screen setup.

v3: __drm_fb_helper_initial_config must hold fb_helper->lock upon
return, I've fumbled that in the deferred setup case (Liviu).

v4: I was blind, redo this all. __drm_fb_helper_initial_config
shouldn't need to reacquire fb_helper->lock, that just confuses
callers. I myself got confused by kernel_fb_helper_lock and somehow
thought it's the same as fb_helper->lock. Tsk.

Also simplify the logic a bit (we don't need two functions to probe
connectors), we can stick much closer to the existing code. And update
some comments I've spotted that are outdated.

v5: Don't pass -EAGAIN to drivers, it's just an internal error code
(Liviu).

v6: Add _and_unlock suffix to clarify locking (Maarten)

Subject: drm/atomic: implement drm_atomic_helper_commit_tail for runtime_pm
 users

The current drm_atomic_helper_commit_tail helper works only if the CRTC is
accessible, and documents an alternative implementation that is supposed to
be used if that happens.

That implementation is then duplicated by some drivers. Instead of
documenting it, let's implement an helper that all the relevant users can
use directly.

Subject: drm/hisilicon: fix build error without fbdev emulation

We cannot reference priv->fbdev outside of the #ifdef:

drivers/net/virtio_net.c:1881:12: error: 'virtnet_restore_up' defined but not used [-Werror=unused-function]
 static int virtnet_restore_up(struct virtio_device *vdev)
drivers/net/virtio_net.c:1859:13: error: 'virtnet_freeze_down' defined but not used [-Werror=unused-function]
 static void virtnet_freeze_down(struct virtio_device *vdev)

As the #ifdef is a bit annoying here, this removes it entirely
and uses an IS_ENABLED() check in it place where needed.

[danvet: One step further, also remove the IS_ENABLED checks, core

Subject: drm/stm: drv: Rename platform driver name

Rename the platform driver name from "stm" to "stm32-display"
for a better readability in /sys/bus/platform/drivers entries.

Note: We keep "stm" as drm_driver.name because it is better
when using "modetest -M stm ..." (even if recent modetest patch
avoids using -M).

Subject: drm/stm: ltdc: add devm_reset_control & platform_get_ressource

Use devm_reset_control_get_exclusive to avoid resource leakage (based
on patch "Convert drivers to explicit reset API" from Philipp Zabel).

Also use platform_get_resource, which is more usual and
consistent with platform_get_irq called later.

The additional arguments in the internal __rproc_boot() function
were dropped in commit 2bfc311a57f5 ("remoteproc: Drop wait in
__rproc_boot()"). The exported rproc_boot() is now just a wrapper
around this internal function, so merge them together.

While at this, also remove the declaration for the previously
cleaned up rproc_boot_nowait() function.

Subject: cpufreq: intel_pstate: Do not use PID-based P-state selection

All systems with a defined ACPI preferred profile that are not
"servers" have been using the load-based P-state selection algorithm
in intel_pstate since 4.12-rc1 (mobile systems and laptops have been
using it since 4.10-rc1) and no problems with it have been reported
to date.  In particular, no regressions with respect to the PID-based
P-state selection have been reported.  Also testing indicates that
the P-state selection algorithm based on CPU load is generally on par
with the PID-based algorithm performance-wise, and for some workloads
it turns out to be better than the other one, while being more
straightforward and easier to understand at the same time.

Moreover, the PID-based P-state selection algorithm in intel_pstate
is known to be unstable in some situation and generally problematic,
the issues with it are hard to address and it has become a
significant maintenance burden.

For these reasons, make intel_pstate use the "powersave" P-state
selection algorithm based on CPU load in the active mode on all
systems and drop the PID-based P-state selection code along with
all things related to it from the driver.  Also update the
documentation accordingly.

-whose parameters were chosen to address a number of different use cases at the

-| ``d_gain_pct``

-Note, however, that achieving desirable results this way generally requires

-is recommended when attempting to do that.

Subject: cpufreq: intel_pstate: Drop ->update_util from pstate_funcs

All systems use the same P-state selection "powersave" algorithm
in the active mode if HWP is not used, so there's no need to provide
a pointer for it in struct pstate_funcs any more.

Drop ->update_util from struct pstate_funcs and make
intel_pstate_set_update_util_hook() use intel_pstate_update_util()
directly.

Subject: drm/vc4: prepare for CEC support

In order to support CEC the hsm clock needs to be enabled in
vc4_hdmi_bind(), not in vc4_hdmi_encoder_enable(). Otherwise you wouldn't
be able to support CEC when there is no hotplug detect signal, which is
required by some monitors that turn off the HPD when in standby, but keep
the CEC bus alive so they can be woken up.

The HDMI core also has to be enabled in vc4_hdmi_bind() for the same
reason.

Subject: drm/vc4: add HDMI CEC support

This patch adds support to VC4 for CEC.  It is under a separate
Kconfig option to keep everyone using VC4 from needing to pull in the
CEC core.

Thanks to Eric Anholt for providing me with the CEC register information.

Subject: memory: atmel-ebi: Fix smc timing return value evaluation

Setting optional EBI/SMC properties through device tree always fails due
to wrong evaluation of the return value of
atmel_ebi_xslate_smc_timings().

If you put some of those properties in your dts file, but not
'atmel,smc-tdf-ns' the local variable 'required' in
atmel_ebi_xslate_smc_timings() stays on 'false' after the first 'if'
block. This leads to setting 'ret' to -EINVAL in the first run of the
following 'for' loop which is then the return value of this function.

However if you set 'atmel,smc-tdf-ns' in the dts file and everything in
atmel_ebi_xslate_smc_timings() works well, it returns the content of
'required' which is 'true' then.

So the function atmel_ebi_xslate_smc_timings() always returns non-zero
which lets its call in atmel_ebi_xslate_smc_config() always fail and
thus returning -EINVAL, so the EBI configuration for this node fails.

Judging from the following code evaluating the local 'required' variable
in atmel_ebi_xslate_smc_config() and the call of caps->xlate_config in
atmel_ebi_dev_setup() it's probably right to only let the call fail if a
negative error code is returned.

Subject: memory: atmel-ebi: Allow t_DF timings of zero ns

As reported in [1] and in [2] it's not possible to set the device tree
property 'atmel,smc-tdf-ns' to zero, although the SoC allows a setting
of 0ns for the t_DF time.

Allow this setting by doing the same thing as in the atmel nand
controller driver by setting ncycles to ATMEL_SMC_MODE_TDF_MIN if zero
is set in the dts.

Subject: memory: atmel-ebi: Fix smc cycle xlate converter

The converter function for translating ns timings in register values was
initialized with a wrong function pointer. This resulted in wrong
register values also for the setup and pulse registers when configuring
the EBI interface trough dts.

Includes a small fix in a comment of the smc driver, which was probably
just a copy'n'paste mistake.

Subject: cpufreq: s5pv210: add missing of_node_put()

for_each_compatible_node performs an of_node_get on each iteration, so a
return from the loop requires an of_node_put.

The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):

// <smpl>
@@
local idexpression n;
expression e,e1,e2;
statement S;
iterator i1;
iterator name for_each_compatible_node;
@@

 for_each_compatible_node(n,e1,e2) {
   ...
(
   of_node_put(n);
|
   e = n
|
   return n;
|
   i1(...,n,...) S
|
+  of_node_put(n);
?  return ...;
)
   ...
 }
// </smpl>

Additionally, call of_node_put on the previous value of np, obtained from
of_find_compatible_node, that is no longer accessible at the point of the
for_each_compatible_node.

Subject: lkdtm: Provide more complete coverage for REFCOUNT tests

The existing REFCOUNT_* LKDTM tests were designed only for testing a narrow
portion of CONFIG_REFCOUNT_FULL. This moves the tests to their own file and
expands their testing to poke each boundary condition.

Since the protections (CONFIG_REFCOUNT_FULL and x86-fast) use different
saturation values and reach-zero behavior, those have to be build-time
set so the tests can actually validate things are happening at the
right places.

Notably, the x86-fast protection will fail REFCOUNT_INC_ZERO and
REFCOUNT_ADD_ZERO since those conditions are not checked (only overflow
is critical to protecting refcount_t). CONFIG_REFCOUNT_FULL will warn for
each REFCOUNT_*_NEGATIVE test since it provides zero-pinning behaviors
(which allows it to pass REFCOUNT_INC_ZERO and REFCOUNT_ADD_ZERO).

Subject: lkdtm: Provide timing tests for atomic_t vs refcount_t

While not a crash test, this does provide two tight atomic_t and
refcount_t loops for performance comparisons:

	cd /sys/kernel/debug/provoke-crash
	perf stat -B -- cat <(echo ATOMIC_TIMING) > DIRECT
	perf stat -B -- cat <(echo REFCOUNT_TIMING) > DIRECT

Looking a CPU cycles is the best way to example the fast-path (rather
than instruction counts, since conditional jumps will be executed but
will be negligible due to branch-prediction).

Subject: ACPI: processor: use dev_dbg() instead of dev_warn() when CPPC probe
 failed

_CPC is a optinal object for processor device so it's
fine for processor devices in DSDT without CPPC data,
but when booting the system with CPPC enabled in the
kernel but without its support in the firmware, I got
lots of warnings on a 64 core system:

[    6.346016] acpi ACPI0007:00: CPPC data invalid or not present
[    6.346028] acpi ACPI0007:01: CPPC data invalid or not present
[    6.346039] acpi ACPI0007:02: CPPC data invalid or not present
[    6.346050] acpi ACPI0007:03: CPPC data invalid or not present
[    6.346063] acpi ACPI0007:04: CPPC data invalid or not present
...
[    6.346737] acpi ACPI0007:3f: CPPC data invalid or not present

This isn't much useful and a little bit noise, so
switch the dev_warn() to dev_dbg().

Subject: scsi: bnx2fc: Plug CPU hotplug race

bnx2fc_process_new_cqes() has protection against CPU hotplug, which relies
on the per cpu thread pointer. This protection is racy because it happens
only partially with the per cpu fp_work_lock held.

If the CPU is unplugged after the lock is dropped, the wakeup code can
dereference a NULL pointer or access freed and potentially reused memory.

Restructure the code so the thread check and wakeup happens with the
fp_work_lock held.

Subject: scsi: bnx2fc: Prevent recursive cpuhotplug locking

The BNX2FC module init/exit code installs/removes the hotplug callbacks with
the cpu hotplug lock held. This worked with the old CPU locking
implementation which allowed recursive locking, but with the new percpu
rwsem based mechanism this is not longer allowed.

Use the _cpuslocked() variants to fix this.

Subject: scsi: bnx2fc: Simplify CPU hotplug code

The CPU hotplug related code of this driver can be simplified by:

1) Consolidating the callbacks into a single state. The CPU thread can be
   torn down on the CPU which goes offline. There is no point in delaying
   that to the CPU dead state

2) Let the core code invoke the online/offline callbacks and remove the
   extra for_each_online_cpu() loops.

Subject: scsi: qedf: Limit number of CQs

FCOE offloading failed with:

[qed_sp_fcoe_func_start:150(sp-0-3b:00.02)]Cannot satisfy CQ amount. CQs
		 requested 8, CQs available 6. Aborting function start
[qed_fcoe_start:821()]Failed to start fcoe
[__qedf_probe:3041]:6: Cannot start FCoE function.

The reason is a newly introduced check in the qed main part. This change
also provides the information about how many CQs are available, so we
simply limit the number of requested CQs..

Subject: qed/qede: Add setter APIs support for RX flow classification

This patch adds support for adding and deleting rx flow
classification rules. Using this user can classify RX flow
constituting of TCP/UDP 4-tuples [src_ip/dst_ip and src_port/dst_port]
to be steered on a given RX queue

From: Rahul Verma <Rahul.Verma@cavium.com>
Date: Wed, 26 Jul 2017 06:07:14 -0700
Subject: qed: Read per queue coalesce from hardware

Retrieve the actual coalesce value from hardware for every Rx/Tx
queue, instead of Rx/Tx coalesce value cached during set coalesce.

Subject: drm/i915: Serialize per-engine resets against new requests

We rely on disabling the execlists (by stopping the tasklet) to prevent
new requests from submitting to the engine ELSP before we are ready.
However, we re-enable the engine before we call init_hw which gives
userspace the opportunity to subit a new request which is then
overwritten by init_hw -- but not before the HW may have started
executing. The subsequent out-of-order CSB is detected by our sanity
checks in intel_lrc_irq_handler().

Subject: drm/i915: Flush the execlist ports if idle

When doing a GPU reset, the CSB register will be trashed and we will
lose any context-switch notifications that happened since the tasklet
was disabled. If we find that all requests on this engine were
completed, we want to make sure that the ELSP tracker is similarly empty
so that we do not feed back in the completed requests upon recovering
from the reset.

Subject: drm/i915: Check execlist/ring status during hangcheck

Before we declare an engine as idle, check if there are any pending
execlist context-switches and if the ring itself reports as idle.
Otherwise, we may be left in a situation where we miss a crucial
execlist event (or something more sinister) yet the requests complete.
Since the seqno write happens, we believe the engine to be truly idle.

Subject: drm/i915: Move idle checks before intel_engine_init_global_seqno()

intel_engine_init_globa_seqno() may be called from an uncontrolled
set-wedged path where we have given up waiting for broken hw and declare
it defunct. Along that path, any sanity checks that the hw is idle
before we adjust its state will expectedly fail, so we simply cannot.
Instead of asserting inside init_global_seqno, we move them to the
normal caller reset_all_global_seqno() as it handles runtime seqno
wraparound.

When the GPU is reset, we want to discard all pending notifications as
either we have manually completed them, or they are no longer

re-enabling the engine (e.g. the interrupt tasklets) in
i915_gem_reset_finish_engine().

Subject: drm/i915: Emit a user level message when resetting the GPU (or
 engine)

Although a banned context will be told to -EIO off if they try to submit
more requests, we have a discrepancy between whole device resets and
per-engine resets where we report the GPU reset but not the engine
resets. This leaves a bit of mystery as to why the context was banned,
and also reduces awareness overall of when a GPU (engine) reset occurs
with its possible side-effects.

Subject: drm/i915/selftests: Exercise independence of per-engine resets

If all goes well, resetting one engine should not affect the operation of
any others. So to test this, we setup a continuous stream of requests
onto to each of the "innocent" engines whilst constantly resetting our
target engine.

Subject: drm/i915: Fix scaler init during CRTC HW state readout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The scaler allocation code depends on a non-zero default value for the
crtc scaler_id, so make sure we initialize the scaler state accordingly
even if the crtc is off. This fixes at least an initial YUV420 modeset
(added in a follow-up patchset by Shashank) when booting with the screen
off: after the initial HW readout and modeset which enables the scaler a
subsequent modeset will disable the scaler which isn't properly
allocated. This results in a funky HW state where the pipe scaler HW
registers can't be modified and the normally black screen is grey and
shifted to the right or jitters.

The problem was revealed by Shashank's YUV420 patchset and first
reported by Ville.

v2:
- In the stable tag also include versions which need backporting (Jani)

Subject: drm/i915: Simplify scaler init during CRTC HW readout

The crtc state starts out being bzero'd, so no need to clear
scaler_users. Also intel_crtc_init_scalers() knows already which
platforms have scalers, so no need for the platform check here.
Similarly intel_crtc_init_scalers() will init scaler_id as required,
so no need to do it here separately.

given platform; ensure this on CHV. This didn't cause an actual problem
since we didn't need to look up power wells which happened to share an
ID.

Mark this new power well as custom, since its programming pattern
doesn't follow that of the rest of VLV/CHV power wells.

From 438b8dc457e7274dba6e988ad3406fddb7bdda45 Mon Sep 17 00:00:00 2001

Subject: drm/i915: Unify power well ID enums
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Atm, the power well IDs are defined in separate platform specific enums,
which isn't ideal for the following reasons:
- the IDs are used by helpers like lookup_power_well() in a platform
  independent way
- the always-on power well is used by multiple platforms and so needs
  now separate IDs, although these IDs refer to the same thing

To make things more consistent use a single enum instead of the two
separate ones, listing the IDs per platform (or set of very similar
platforms like all GEN9/10). Replace the separate always-on power
well IDs with a single ID.

While at it also add a note clarifying the distinction between regular
power wells that follow a common programming pattern and custom ones
that are programmed in some other way. The IDs for regular power wells
need to stay fixed, since they also define the request and state HW flag
positions in their corresponding power well control register(s).

v2:
- Add comment about id to req,status bit mapping to the enum. (Rodrigo)

This didn't cause a problem so far, since we didn't need to look up

Subject: drm/i915: Check for duplicated power well IDs

Check that all the power well IDs are unique on the given platform.

v2:
- Fix using BIT_ULL() instead of BIT() for 64 bit mask.
v3:
- Move the check to a separate function. (Ville)

Subject: drm/i915/bxt, glk: Give a proper name to the power well struct phy
 field

Follow-up patches will add new fields to the i915_power_well struct that
are specific to the hsw_power_well_ops helpers. Prepare for this by
changing the generic 'data' field to a union of platform specific
structs.

Subject: drm/i915/gen9+: Remove redundant power well state assert during
 enabling

We check already for power wells that are unexpectedly on (or forced on)
during power well disabling. Those checks also account for other
power well requesters like KVMR or DEBUG. As such this check is
redundant, let's remove it to simplify things.

Subject: drm/i915/gen9+: Remove redundant state check during power well
 toggling

Atm we enable/disable a power well only if it wasn't already
enabled/disabled respectively. The only reason for this I can think of
is to save the extra MMIO writes. Since the HW state matches the power
well's usage counter most of the time the overhead due to these MMIOs is
insignificant. Let's simplify the code by making the writes
unconditional.

Subject: drm/i915/hsw, bdw: Split power well set to enable/disable helpers

We can reduce the code indentation by splitting the set helper to
separate enable/disable helpers. This also allows us to unify the
HSW/BDW and GEN9+ power well ops in follow-up patches, which introduces
some differences between the enable and disable helpers.

While at it also remove the redundant enable/disable debug messages,
the same info is printed already elsewhere.

Subject: drm/i915/hsw+: Unify the hsw/bdw and gen9+ power well req/state
 macros

Although on HSW/BDW there is only a single display global power well,
it's programmed the same way as other GEN9+ power wells. This also
means we can get at the HSW/BDW request and status flags the same way
it's done on GEN9+ by assigning the corresponding HSW/BDW power well ID.
This ID was assigned in a recent patch, so we can now switch to using
the same macros everywhere on HSW+.

Updating the HSW power well control register with RMW is not strictly
necessary, but this will allow us to use the same code for GEN9+.

Subject: drm/i915/hsw, bdw: Add irq_pipe_mask, has_vga power well attributes

The pattern of a power well backing a set of pipe IRQ or VGA
functionality applies to all HSW+ platforms. Using power well attributes
instead of platform checks to decide whether to init/reset pipe IRQs and
VGA correspondingly is cleaner and it allows us to unify the HSW/BDW and
GEN9+ power well code in follow-up patches.

Also use u8 for pipe_mask in related helpers to match the type in the
power well struct.

v2:
- Use u8 instead of u32 for irq_pipe_mask. (Ville)

v3:
- Use u8 for pipe_mask in related helpers too for clarity.

Subject: drm/i915/hsw, bdw: Wait for the power well disabled state

Similarly to GEN9+ waiting for the power well disabled state is a safer
option and also provides diagnostic info if the disabling didn't succeed
or the power well was forced on by an external requester. While at it
also use the existing GEN9+ helper to wait for the enabled state.

Subject: drm/i915/hsw+: Add has_fuses power well attribute

The pattern of a power well backing a set of fuses whose initialization
we need to wait for during power well enabling is common to all GEN9+
platforms. Adding support for this to the HSW power well enable helper
allows us to use the HSW/BDW power well code for GEN9+ as well in a
follow-up patch.

v2:
- Use an enum for power gates instead of raw numbers. (Ville)

Subject: drm/i915/gen9+: Unify the HSW/BDW and GEN9+ power well helpers

After the previous refactorings the HSW/BDW and GEN9+ power well helpers
are practically identical, so use the HSW power well helpers for GEN9+
too. This means using the HSW power well ops instead of the SKL one and
setting the irq_pipe_mask, has_vga and has_fuses attributes as needed.

v2:
- Rebased on v2 of patch 15.

Subject: drm/i915: add config function for YCBCR420 outputs

This patch checks encoder level support for YCBCR420 outputs.
The logic goes as simple as this:
If the input mode is YCBCR420-only mode: prepare HDMI for
YCBCR420 output, else continue with RGB output mode.

It checks if the mode is YCBCR420 and source can support this
output then it marks the ycbcr_420 output indicator into crtc
state, for further staging in driver.

V2: Split the patch into two, kept helper functions in DRM layer.
V3: Changed the compute_config function based on new DRM API.
V4: Rebase
V5: Rebase
V6: Check and handle YCBCR420-only modes, discard the property
    based approach (Ville)
V7: Addressed review comments from Ville
    - add else case in 12BPC check.
    - extract ycbcr420 state inside hdmi_12bpc_possible function.
V8: Addressed review comments from Ville
    - Remove extra blank lines.
    - Remove "HDMI" from the description of ycbcr420 state variable.
    - Remove local variable, use crtc_state->ycbcr420 instead.
    Added r-b from Ville.
V9: Rebase
V10: Added r-b from Imre

Subject: drm/i915: prepare scaler for YCBCR420 modeset

To get a YCBCR420 output from intel platforms, we need one
scaler to scale down YCBCR444 samples to YCBCR420 samples.

This patch:
- Does scaler allocation for HDMI ycbcr420 outputs.
- Programs PIPE_MISC register for ycbcr420 output.

V2: rebase
V3: rebase
V4: rebase
V5: addressed review comments from Ander:
    - No need to check both scaler_user && hdmi_output.
      Check for scaler_user is enough.
V6: rebase
V7: Do not create a new scaler user, use existing pipe scaler user.
V8: rebase
V9: Addressed review comments from Ville:
    - Remove leftover comment for HDMI scaler user.
    - Remove unnecessary blank line.
    - Make scaler alocation failure a DEBUG log instead of ERROR.
    Added r-b from Ville
V10: Update commit message as per latest code (Imre)
     Added r-b from Imre

Subject: drm/i915: prepare pipe for YCBCR420 output

To get HDMI YCBCR420 output, the PIPEMISC register should be
programmed to:
- Generate YCBCR output (bit 11)
- In case of YCBCR420 outputs, it should be programmed in full
  blend mode to use the scaler in 5x3 ratio (bits 26 and 27)

This patch:
- Adds definition of these bits.
- Programs PIPEMISC for YCBCR420 outputs.
- Adds readouts to compare HW and SW states.

V2: rebase
V3: rebase
V4: rebase
V5: added r-b from Ander
V6: Handle only YCBCR420 outputs (ville)
V7: rebase
V8: Addressed review comments from Ville
    - Add readouts for state->ycbcr420 and 420 pixel_clock.
    - Handle warning due to mismatch in clock for ycbcr420 clock.
    - Rename PIPEMISC macros to match the Bspec.
    - Add a debug print stating if YCBCR 4:2:0 output enabled.
    Added r-b from Ville
V9: Addressed review comments from Imre:
    - Add 420 mode clock adjustment in intel_hdmi_mode_valid to
      prevent 420_only modes getting rejected for high clock.
    - Add port clock adjustment for ycbcr420 modes in ddi_get_clock
    - Rename macros as per Ville's suggestion.
    - Remove unnecessary wl changes.
V10: Added r-b from Imre
V11: Fixed faulty dotclock handling, and addressed missing comment
     from previous set of review comments (Imre)
V12: Fixed dotclock for 12bpc too, removed 420 check for GEN < 10

Subject: drm/i915: prepare csc unit for YCBCR420 output

To support ycbcr output, we need a pipe CSC block to do
RGB->YCBCR conversion.

Current Intel platforms have only one pipe CSC unit, so
we can either do color correction using it, or we can perform
RGB->YCBCR conversion.

This function adds a csc handler, which uses recommended bspec
values to perform RGB->YCBCR conversion (target color space BT709)

V2: Rebase
V3: Rebase
V4: Rebase
V5: Addressed review comments from Ander
    - Remove extra line added in the patch
    - Add the spec details in the commit message
    - Combine two if(cond) while calling intel_crtc_compute_config
V6: Handle YCBCR420 outputs only (Ville)
V7: Addressed review comments from Ville:
    - Add description about target colorspace
    - Remove the comments from CSC function
    - DRM_DEBUG->DEBUG_KMS for atomic failure due to CSC unit busy
    - Remove unnecessary debug message about YCBCR420 possibe
V8: Addressed review comments from Ville:
    - Remove extra comment, not required.
    - Do not add extra variable for CTM, reuse pipe_config

Subject: drm/i915/glk: set HDMI 2.0 identifier

This patch sets the is_hdmi2_src identifier in drm connector
for GLK platform. GLK contains a native HDMI 2.0 controller.
This identifier will help the EDID handling functions to save
lot of work which is specific to HDMI 2.0 sources.

We require the caller to ensure that the packets they wish to emit into
the CS ring are qword aligned (i.e. have an even number of dwords).
Double check this.

Subject: drm/i915: Don't touch fence->error when resetting an innocent request

If the request has been completed before the reset took effect, we don't
need to mark it up as being a victim. Touching fence->error after the
fence has been signaled is detected by dma_fence_set_error() and
triggers a BUG:

At first glance this looks to be related to commit c64992e035d7
("drm/i915: Look for active requests earlier in the reset path"), but it
could easily happen before as well. On the other hand, we no longer
logged victims due to the active_request being dropped earlier.

v2: Be trickier to unwind the incomplete request as we cannot rely on
request retirement for the lockless per-engine reset.
v3: Reprobe the active request at the time of the reset.

Subject: drm/i915: Squelch reset messages during selftests

During our selftests, we try reseting the GPU tens of thousands of
times, flooding the dmesg with our reset spam drowning out any potential
warnings. Add an option to i915_reset()/i915_reset_engine() to specify a
quiet reset for selftesting.

each struct.

Subject: drm/i915/cnl: Fix loadgen select programming on ddi vswing sequence

The condition for setting the Loadgen Select bit of
PORT_TX_DW4 register during DDI Vswing Sequence should be
Bit rate <=6 GHz whereas the existing code checks only
Bit Rate < 6GHz. This patch fixes this condition.
While at it also remove the redundant paranthesis.

Subject: drm/i915: Remove assertion from raw __i915_vma_unpin()

After we detect a i915_vma pin overflow, we call __i915_vma_unpin to
cleanup. However, on an overflow the pin_count bitfield will be zero,
triggering an assertion, even though we the intention is to merely warn
and report the error back to the user (as historically the culprit has
be a leak in the display code).

Subject: drm/i915: Only mark the execobject as pinned on success

If we fail to acquire a fence (for old school fenced GPU access) then we
unwind the vma reservation, including its pin. However, we were making
the execobject as holding the pin before erring out, leading to a double
unpin:

Subject: drm/i915: Only skip updating execobject.offset after error

I was being overly paranoid in not updating the execobject.offset after
performing the fallback copy where we set reloc.presumed_offset to -1.
The thinking was to ensure that a subsequent NORELOC execbuf would be
forced to process the invalid relocations. However this is overkill so
long as we *only* update the execobject.offset following a successful
update of the relocation value witin the batch. If we have to repeat the
execbuf due to a later interruption, then we may skip the relocations on
the second pass (honouring NORELOC) since the execobject.offset match
the actual offsets (even though reloc.presumed_offset is garbage).

Subsequent calls to execbuf with NORELOC should themselves ensure that
the reloc.presumed_offset have been corrected in case of future
migration.

Reporting back the actual execobject.offset, even when
reloc.presumed_offset is garbage, ensures that reuse of those objects
use the latest information to avoid relocations.

Subject: drm/i915: Force CPU synchronisation even if userspace requests ASYNC

The goal here was to minimise doing any thing or any check inside the
kernel that was not strictly required. For a userspace that assumes
complete control over the cache domains, the kernel is usually using
outdated information and may trigger clflushes where none were
required.

However, swapping is a situation where userspace has no knowledge of the
domain transfer, and will leave the object in the CPU cache. The kernel
must flush this out to the backing storage prior to use with the GPU. As
we use an asynchronous task tracked by an implicit fence for this, we
also need to cancel the ASYNC flag on the object so that the object will
wait for the clflush to complete before being executed. This also absolves
userspace of the responsibility imposed by commit 77ae9957897d ("drm/i915:
Enable userspace to opt-out of implicit fencing") that its needed to ensure
that the object was out of the CPU cache prior to use on the GPU.

Fixes: 77ae9957897d ("drm/i915: Enable userspace to opt-out of implicit fencing")

Subject: drm/i915: Handle msr read failure gracefully

When reading the i915_energy_uJ debugfs file, it tries to fetch
MSR_RAPL_POWER_UNIT, which might not be available, like in a vm
environment, causing the exception shown below.

We can easily prevent it by doing a rdmsrl_safe read instead, which will
handle the exception, allowing us to abort the debugfs file read.

This was caught by the new igt@debugfs_test@read_all_entries testcase in
the CI.

Subject: drm/i915: Trim struct_mutex usage for kms

Reduce acquisition of struct_mutex to the critical regions that must
hold it; for KMS, we need struct_mutex currently only for the purpose of
pinning/unpinning the framebuffer's VMA into the global GTT. This allows
us to avoid taking the struct_mutex when disabling the CRTC (i.e. NULL
framebuffer objects) before a reset. (Not yet achieving the full goal of
avoiding the strut_mutex nesting, but good enough to break the first
half of the reset deadlock.)

v2: Keep pages pinning inside struct_mutex for the moment.

Subject: drm/i915: Call the unlocked version of i915_gem_object_get_pages()

When we hold for the lock for swapping out the shmem pages for the
physically contiguous pages, we have to call the unlocked version of
get_pages!

Subject: drm/i915: Rework sdvo proxy i2c locking

lockdep complaints about a locking recursion for the i2c bus lock
because both the sdvo ddc proxy bus and the gmbus nested within use
the same locking class. It's not really a deadlock since we never nest
the other way round, but it's annoying.

Fix it by pulling the gmbus locking into the i2c lock_ops for both
i2c_adapater and making sure that the ddc_proxy_xfer function is
entirely lockless.

Re-layouting the extracted function resulted in some whitespace
cleanups, I figured we might as well keep them.

v2: Review from Chris:
- s/locked/unlocked/ since I got the naming backwards
- Use the vfuncs of the proxied adatper instead of re-rolling copies.
  That's more consistent with the other proxying we're doing.

Subject: drm/i915/sdvo: Shut up state checker with hdmi cards on gen3

The hdmi bits simply don't exist, so nerf them. I think audio doesn't
work on gen3 at all, and for the limited color range we should
probably use the colorimetry sdvo paramater instead of the bit in the
port.

But fixing sdvo isn't my goal, I just want to get the backtrace out of
the way, and this takes care of that.

Still, while at it fix the missing read-out of the gen4 audio bit,
maybe that part even works ...

v2: Instead of trying to plug the damage in ->compute_config() make
sure we never set intel_sdvo->is_hdmi, which stops the bad state at
the source. Suggested by Chris Wilson. Also make sure we don't break
this by accident by putting a WARN_ON in place.

Subject: mwifiex: correct channel stat buffer overflows

mwifiex records information about various channels as it receives scan
information. It does this by appending to a buffer that was sized
to the max number of supported channels on any band, but there are
numerous problems:

(a) scans can return info from more than one band (e.g., both 2.4 and 5
    GHz), so the determined "max" is not large enough
(b) some firmware appears to return multiple results for a given
    channel, so the max *really* isn't large enough
(c) there is no bounds checking when stashing these stats, so problems
    (a) and (b) can easily lead to buffer overflows

Let's patch this by setting a slightly-more-correct max (that accounts
for a combination of both 2.4G and 5G bands) and adding a bounds check
when writing to our statistics buffer.

Due to problem (b), we still might not properly report all known survey
information (e.g., with "iw <dev> survey dump"), since duplicate results
(or otherwise "larger than expected" results) will cause some
truncation. But that's a problem for a future bugfix.

(And because of this known deficiency, only log the excess at the WARN
level, since that isn't visible by default in this driver and would
otherwise be a bit too noisy.)

Subject: scsi: sg: only check for dxfer_len greater than 256M

Don't make any assumptions on the sg_io_hdr_t::dxfer_direction or the
sg_io_hdr_t::dxferp in order to determine if it is a valid request. The
only way we can check for bad requests is by checking if the length
exceeds 256M.

Subject: HID: introduce hid_is_using_ll_driver

Although HID itself is transport-agnostic, occasionally a driver may
want to interact with the low-level transport that a device is connected
through. To do this, we need to know what kind of bus is in use. The
first guess may be to look at the 'bus' field of the 'struct hid_device',
but this field may be emulated in some cases (e.g. uhid).

More ideally, we can check which ll_driver a device is using. This
function introduces a 'hid_is_using_ll_driver' function and makes the
'struct hid_ll_driver' of the four most common transports accessible
through hid.h.

From 09dc28acaec74d7467c7c9b81dc8676e5bc957ce Mon Sep 17 00:00:00 2001
From: Jason Gerecke <killertofu@gmail.com>
Date: Mon, 24 Jul 2017 09:46:19 -0700
Subject: HID: wacom: Improve generic name generation

The 'wacom_update_name' function is responsible for producing names for
the input device nodes based on the hardware device name. Commit f2209d4
added the ability to strip off prefixes like "Wacom Co.,Ltd." where the
prefix was immediately (and redundantly) followed by "Wacom". The
2nd-generation Intuos Pro 2 has such a prefix, but with a small error
(the period and comma are swapped) that prevents the existing code from
matching it. We're loath to extend the number of cases out endlessly and
so instead try to be smarter about name generation.

We observe that the cause of the redundant prefixes is HID combining the
manufacturer and product strings of USB devices together. By using the
original product name (with "Wacom" prefixed, if it does not already
exist in the string) we can bypass the gyrations to find and remove
redundant prefixes. Other devices either don't have a manufacturer string
that needs to be removed (Bluetooth, uhid) or should have their name
generated from scratch (I2C).

Subject: spi: pxa2xx: Revert "Only claim CS GPIOs when the slave device is
 created"

There is a valid case to call setup() following by setup_cs() several
times for the same chip.

With the commit

  676a4e3bab44 ("spi: pxa2xx: Only claim CS GPIOs when the slave device is created")

it is not possible anymore due to GPIO line being requested already
during the first call to setup_cs().

For now, revert the commit to make things work again.

Subject: nfp: remove the probe deferral when FW not present

We use a hack to defer probe when firmware was not pre-loaded
or found on disk.  This helps in case users forgot to include
firmware in initramfs, the driver will most likely get another
shot at probing after real root is mounted.

This is not for what EPROBE_DEFER is supposed to be used, and
when FW is completely missing every time new device is probed
NFP will reprobe spamming kernel logs.

Remove this hack, users will now have to make sure the right
firmware image is present in initramfs if nfp.ko is placed
there or built in.

Subject: nfp: look for firmware image by device serial number and PCI name

We generally look up firmware by card type, but that doesn't allow
users who have more than one card of the same type in their system
to select firmware per adapter.

Unfortunately user space firmware helper seems fraught with
difficulties and to be on its way out.  In particular support for
handling firmware uevents have been dropped from systemd and most
distributions don't enable the FW fallback by default any more.

To allow users selecting firmware for a particular device look up
firmware names by serial and pci_name().  Use the direct lookup to
disable generating uevents when enabled in Kconfig and not print
any warnings to logs if adapter-specific files are missing.  Users
can place in /lib/firmware/netronome files named:

pci-${pci_name}.nffw
serial-${serial}.nffw

to target a specific card.  E.g.:

pci-0000:04:00.0.nffw
pci-0000:82:00.0.nffw
serial-00-aa-bb-11-22-33-10-ff.nffw

We use the full serial number including the interface id, as it
appears in lspci output (bytes separated by '-').

Subject: nfp: only use direct firmware requests

request_firmware() will fallback to user space helper and may cause
long delays when driver is loaded if udev doesn't correctly handle
FW requests.  Since we never really made use of the user space
helper functionality switch to the simpler request_firmware_direct()
call.  The side effect of this change is that no warning will be
printed when the FW image does not exists.  To help users figure
out which FW file is missing print a info message when we request
each file.

Since commit a390d1f379cf ("phylib: convert state_queue work to
delayed_work"), the PHYLIB state machine was converted to use delayed
workqueues, yet some functions were still referencing the PHY library
timer in their comments, fix that and remove the now unused
linux/timer.h include.

Subject: drm/bridge: tc358767: fix probe without attached output node

The output node of the TC358767 is only used if another bridge is chained
behind it. Panels attached to the TC358767 can be detected using the usual
DP AUX probing. This restores the old behavior of ignoring the output if
no endpoint is found.

Subject: staging: unisys: visorbus: Constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

Subject: staging: greybus: Remove unnecessary platform_set_drvdata

Unnecessary platform_set_drvdata() has been removed since the driver
core clears the driver data to NULL after device release or on
probe failure. There is no need to manually clear the device
driver data to NULL.

The Coccinelle semantic patch used to make this change is as follows:
//<smpl>
@@
struct platform_device *pdev;
@@
- platform_set_drvdata(pdev, NULL);

Subject: crypto: caam - free qman_fq after kill_fq
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kill_fq removes a complete frame queue, it needs to free the qman_fq
in the last. Else kmemleak will report the below warning:

And check where the function kill_fq() is called to remove
the additional kfree to qman_fq and avoid re-calling the released qman_fq.

Subject: crypto: ccp - Fix base RSA function for version 5 CCPs

Version 5 devices have requirements for buffer lengths, as well as
parameter format (e.g. bits vs. bytes). Fix the base CCP driver
code to meet requirements all supported versions.

Subject: spi: bcm-qspi: Remove hardcoded settings and spi-nor.h dependency

The newly added broadcom qspi driver in drivers/spi produces a build
warning when CONFIG_MTD is disabled:
include/linux/mtd/cfi.h:76:2: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. [-Werror=cpp]

There has been discussion on this in the link provided below. This fix in
SPI controller drivers implementing the ->spi_flash_read handler, now uses the
settings provided inside the 'struct spi_flash_read_message' parameter instead
of hardcoding them. Made changes to bcm_qspi_bspi_set_flex_mode() to set the BSPI
controller using the passed msg structure and remove the need to include
<linux/mtd/spi-nor.h> file by removing all use of SPINOR_OP_READ* macros.

Fixes: 4e3b2d236fe0 ("spi: bcm-qspi: Add BSPI spi-nor flash controller driver")

Subject: drm/i915: Remove unused i915_err_print_instdone

Just a simple code cleanup, below commit forgot to remove a
function which it made unused:

 commit eaa14c24864ecfc60fb591f3b20747af7c67d446
 Author: Chris Wilson <chris@chris-wilson.co.uk>
 Date:   Wed Oct 19 13:52:03 2016 +0100

  drm/i915: Stop reporting error details in dmesg as well as the error-state

  As we already capture all the information from the registers into the
  error-state, also dumping that to dmesg just generates noise that upsets
  CI and users alike (and doesn't provide us with any more information).

v2: Chris Wilson dag out the relevant commit. Commit msg updated.

Subject: spi: pxa2xx: Don't touch CS pin until we have a transfer pending

GPIO descriptors, when being requested, may configure pin at the same
time. In case of SPI chip select we shouldn't do any assumptions of the
state of pin since we don't know yet what chip is connected there and if
it uses high or low active state. So, leave the state of pin as is until
transfer will start.

Whenever new fsm_state enum element is added, fsm_state array
also needs to be updated. If this change is missed, we may end
up doing invalid access in array. BUILD_BUG_ON check will help
to avoid this problem.

Sometimes it's observed that we get interrupt/Rx frame when device is
already detached from mac80211. In this case couple of error messages
are displayed in dmesg log. This patch corrects the order so that
disconnection will happen cleanly

Subject: rsi: USB tx headroom cleanup

USB headroom is added while submitting the data to URB as per
firmware's requirement. This logic is moved to rsi_usb_card_write() so
that caller need not worry about it.

Subject: rsi: Optimise sdio claim and release host

SDIO host is already claimed in our interrupt handler. Some lower
level APIs claims host while performing SDIO read or write operations.
Let's use sdio_irq_task variable to check if we are in interrupt
context and claim/release the host accordingly.

Subject: rsi: use separate mutex lock for receive thread

Deadlock issue is observed during our stress tests. The root
cause for the issue is same lock is used between tx and rx threads.

This patch adds a separate mutex lock for rx thread to resolve
the problem.

Subject: rsi: add common structures needed for command packets

All internal management packets (command packets) use some common
fields and some packet specific fields for packet descriptors.
This patch adds some common structures which are needed for all
command packets.

Subject: rsi: immediate wakeup bit and priority for TX command packets

For all TX command packets immediate wakeup bit needs to be
set in descriptor. This will make sure device will wakeup if it
is in any sleep state. Priority of the packet is also set.

Subject: rsi: remove unnecessary check for 802.11 management packet

The function rsi_mgmt_pkt_to_core() is for passing the 802.11
management frames to mac80211. So, it is unnecessary to check
again for the frame type 802.11 management in this function.
It can be checked before passing to this function.

Subject: mwifiex: reunite copy-and-pasted remove/reset code

When PCIe FLR code was added, it explicitly copy-and-pasted much of
mwifiex_remove_card() into mwifiex_shutdown_sw(). This is unnecessary,
as almost all of the code should be reused.

Let's reunite what we can for now.

The only functional changes for now:

 * call netif_device_detach() in the remove() code path -- this wasn't
   done before, but it really should be a no-op, when the device is
   getting totally unregistered soon anyway

 * call the ->down_dev() driver callback only after we've finished all
   SW teardown -- this should have no significant effect, since the only
   user (pcie.c) does very minimal work there, and it doesn't matter
   that we reorder this

Subject: mwifiex: reset interrupt status across device reset

When resetting the device, we might have queued up interrupts that
didn't get a chance to finish processing. We really don't need to handle
them at this point; we just want to make sure they don't cause us to try
to process old commands from before the device was reset.

Subject: mwifiex: pcie: don't allow cmd buffer reuse after reset

In rogue cases (due to other bugs) it's possible we try to process an
old command response *after* resetting the device. This could trigger a
double-free (or the SKB can get reallocated elsewhere...causing other
memory corruptions) in mwifiex_pcie_process_cmd_complete().

For safety (and symmetry) let's always NULL out the command buffer as we
free it up. We're already doing this for the command response buffer.

Subject: mwifiex: re-register wiphy across reset

In general, it's helpful to use the same code for device removal as for
device reset, as this tends to have fewer bugs. Let's move the wiphy
unregistration code into the common reset and removal code.

In particular, it's very hard to properly handle the reset sequence when
something fails. Currently, if mwifiex_reinit_sw() fails, we've failed
to unregister the associated wiphy, and so running something as simple
as "iw phy" can trigger an OOPS, as the wiphy still has hooks back into
freed mwifiex data structures. For example, KASAN complained:

This all goes away if we just tear down the wiphy on the way down, and
set it back up if/when we bring the device back up.

Subject: mwifiex: unregister wiphy before freeing resources

It's possible for some control interfaces (e.g., scans, set freq) to be
active after we've stopped our main work queue and the netif TX queues.
These don't get completely shut out until we've unregistered the wdevs
and wiphy.

So let's only free command buffers and poison our lists after
wiphy_unregister().

This resolves various use-after-free issues seen when resetting the
device.

Subject: mwifiex: don't short-circuit netdev notifiers on interface deletion

When we leave the delete interface function, there are still netdev
hooks that might try to process the device. We're short-circuiting some
of that by changing the interface type and clearing ieee80211_ptr. This
means we skip NETDEV_UNREGISTER_FINAL in cfg80211. Fortunately, that is
currently a no-op.

We don't need most of the cleanup here anyway:

 * the connection state will get (un)set as part of the disconnect
   process (which cfg80211 already initiates for us)
 * the interface type doesn't actually need to be cleared at all (it'll
   trigger a WARN_ON() in cfg80211 if we do)
 * the iee80211_ptr isn't really "ours" to clear anyway

So stop resetting those 3 things.

Despite the name (and meticulous comments), this function frees no
memory and does not touch any locks. All it does is "delete" the list
heads -- which just means they'll be dangling, and we'll need to re-init
them if we use them again.

It seems like this code would work OK as a sort of canary for using the
list after we've torn everything down, so it's fine to keep the code;
let's just get the name and comments to match what's actually happening.

Subject: mwifiex: drop 'add_tail' param from mwifiex_insert_cmd_to_pending_q()

It's always called with 'true' -- we only determine it 'false' locally
within this function. So drop the parameter.

Also, this should be 'bool' (since we use true/false), not 'u32'.

After removing the interrupt loop in commit 5d5ddb5e0d9b ("mwifiex:
pcie: don't loop/retry interrupt status checks"), there is practically
zero difference between mwifiex_process_pcie_int() (which handled legacy
PCI interrupts and MSI interrupts) and mwifiex_process_msix_int() (which
handled MSI-X interrupts). Let's add the one relevant line to
mwifiex_process_pcie_int() and kill the copy-and-paste.

Subject: mwifiex: debugfs: allow card_reset() to cancel things

The card_reset() implementation should be setting our state flags and
cancelling commands for us (i.e., in mwifiex_shutdown_drv()), so let's
not do it here.

Also, this debugfs file is useful for testing and debugging the reset
feature, so we shouldn't do extra preparatory steps here, as that might
cause different reset behavior, which could either cause new bugs or
paper over existing ones that this debug feature should otherwise help
us catch.

Subject: mwifiex: pcie: disable device DMA before unmapping/freeing buffers

In testing the mwifiex reset code path, I've noticed KASAN complaining
about some "overwritten poison values" in our RX buffer descriptors.
Because KASAN didn't notice this at the time of a CPU write, this seems
to suggest that the device is writing to this memory.

This makes a little sense, because when resetting, we don't necessarily
expect the device to be responsive, so we don't have a chance to disable
everything cleanly.

We can at least take the precaution of disabling DMA for the device
though, and in my testing that seems to clear up this particular issue.

This patch reorders the removal path so that we disable the device
*before* releasing our last PCIe buffers, and it clears/sets the bus
master feature from the PCI device when resetting.

Along the way, remove the insufficient (and confusing) error path in
mwifiex_pcie_up_dev() (it doesn't unwind things well enough, and it
doesn't propagate its errors upward anyway).

Subject: mwifiex: pcie: remove unnecessary 'pdev' check

'card->dev' is initialized once and is never cleared. Drop the
unnecessary "safety" check, as it simply obscures things, and we don't
do this check everywhere (and therefore it's not really "safe").

We got a compile warning shows below:

'mwifiex_sdio_remove':
drivers/net/wireless/marvell/mwifiex/sdio.c:377:6: warning: variable
'ret' set but not used [-Wunused-but-set-variable]

Per the code, it didn't check if mwifiex_sdio_read_fw_status
finish successfully. We should at least check the return of
mwifiex_sdio_read_fw_status, otherwise the following check of
firmware_stat and adapter->mfg_mode is pointless as the device
is probably dead.

things, leading to a panic.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

Subject: rtlwifi: Uses addr1 instead DA to determine broadcast and multicast
 addr.

We should check addr1 to indicate a packet as broadcast or multicast
in tx desc. An obvious example, a STA transmit an *unicast* ARP packet
where addr1 and DA are the addresses of AP and broadcast respectively.

Use rtlpriv instead of rtlhal as argument, so driver and btcoex use
the same definitions.

Subject: rtlwifi: rtl8821ae: Fix HW_VAR_NAV_UPPER operation

The cast here is wrong.  We want to cast the pointer but we accidentally
do a no-op cast of the value.  We normally want to set us_nav_upper to
WIFI_NAV_UPPER_US (30000) but because of this bug we instead set it to
184 on little endian systems and 0 on big endian ones.

Subject: IB/cma: Fix default RoCE type setting

The initial patch for changing the stack to use RoCEv2 GIDs by default
set the CMA_PREFERRED_ROCE_GID_TYPE to an incorrect value.  Instead of
an absolute value, we needed to set the right bit in a bitmask.  Correct
the default setting so we use RoCEv2 by default.

Subject: RDMA/hns: fix build regression

The 0day build system flags implicit includes as errors.  A patch from
Matan Barak to allow hns_roce, an aarch64 specific RDMA driver, to be
built on other arches, but it resulted in build regressions.  The
problem is that hns_roce_device.h needs a definition for __raw_writeq
but did not have an include to provide it.  Add <linux/io.h> as an
include to resolve the issue.

Subject: drm/vc4: Add an ioctl for labeling GEM BOs for summary stats

This has proven immensely useful for debugging memory leaks and
overallocation (which is a rather serious concern on the platform,
given that we typically run at about 256MB of CMA out of up to 1GB
total memory, with framebuffers that are about 8MB ecah).

The state of the art without this is to dump debug logs from every GL
application, guess as to kernel allocations based on bo_stats, and try
to merge that all together into a global picture of memory allocation
state.  With this, you can add a couple of calls to the debug build of
the 3D driver and get a pretty detailed view of GPU memory usage from
/debug/dri/0/bo_stats (or when we debug print to dmesg on allocation
failure).

The Mesa side currently labels at the gallium resource level (so you
see that a 1920x20 pixmap has been created, presumably for the window
system panel), but we could extend that to be even more useful with
glObjectLabel() names being sent all the way down to the kernel.

(partial) example of sorted debugfs output with Mesa labeling all
resources:

               kernel BO cache:  16392kb BOs (3)
       tiling shadow 1920x1080:   8160kb BOs (1)
       resource 1920x1080@32/0:   8160kb BOs (1)
scanout resource 1920x1080@32/0:   8100kb BOs (1)
                        kernel:   8100kb BOs (1)

v2: Use strndup_user(), use lockdep assertion instead of just a
    comment, fix an array[-1] reference, extend comment about name
    freeing.

Subject: drm/vc4: Convert more lock requirement comments to lockdep
 assertions.

Since I do my development with lockdep on, this will help make sure I
don't introduce bugs here.

Subject: staging: pi433: return -EFAULT if copy_to_user() fails

copy_to_user() to user returns the number of bytes that weren't copied,
but we should be returning -EFAULT to the user.

Subject: staging: pi433: depends on SPI

The pi433 driver uses SPI interfaces so it should depend on SPI.
Also, the "default n" can be removed since that is already the
default.

Fixes these build errors when SPI is not enabled:

The function rf69_set_bandwidth_intern is local to the source

break overly wide line.

Cleans up sparse warning:

Subject: staging: pi433: use div_u64 for 64-bit division

I ran into this link error on an ARM OABI build:

drivers/staging/pi433/rf69.o: In function `rf69_set_frequency':
rf69.c:(.text+0xc9c): undefined reference to `__udivdi3'

No idea why I didn't see it with the default EABI configurations,
but the right solution here seems to be to use div_u64()
to get the external division implementation.

Subject: staging: vboxvideo: select GENERIC_ALLOCATOR

The vboxvideo code uses various gen_pool_* functions, so it needs
lib/genalloc.c to be built. In some configs this is not happening,
so add select GENERIC_ALLOCATOR to the Kconfig file to enforce this.

Note all other Kconfig references to GENERIC_ALLOCATOR also use select.

Module parameter vbox_modeset and structure vbox_bo_driver do not need to
be in global scope and hence can be made static.

Cleans up a couple of sparse warnings:
symbol 'vbox_modeset' was not declared. Should it be static?
symbol 'vbox_bo_driver' was not declared. Should it be static?

Subject: staging: gs_fpgaboot: add buffer overflow checks

Four fields in struct fpgaimage are char arrays of length MAX_STR (256).
The amount of data read into these buffers is controlled by a length
field in the bitstream file read from userspace. If a corrupt or
malicious firmware file was supplied, kernel data beyond these buffers
can be overwritten arbitrarily.

This patch adds a check of the bitstream's length value to ensure it
fits within the bounds of the allocated buffers. An error condition is
returned from gs_read_bitstream if any of the reads fail.

Subject: staging: gs_fpgaboot: change char to u8

The bitstream storage variables were changed from char to u8 arrays to
prevent issues such as negative lengths. This change makes the code
compatible with the "data" field in "struct firmware" which is of type
u8.

Subject: tinydrm: repaper: add CONFIG_THERMAL dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The new RePaper driver uses the thermal subsystem, and fails to link
when it is built-in but thermal is a loadable module:

drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_probe':
repaper.c:(.text+0x540): undefined reference to `thermal_zone_get_zone_by_name'
drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_fb_dirty':
repaper.c:(.text+0xff4): undefined reference to `thermal_zone_get_temp'

This adds another Kconfig dependency to prevent the broken configuration,
forcing repaper to be a module too.

Subject: dma-buf/sync_file: Allow multiple sync_files to wrap a single
 dma-fence

Up until recently sync_file were create to export a single dma-fence to
userspace, and so we could canabalise a bit insie dma-fence to mark
whether or not we had enable polling for the sync_file itself. However,
with the advent of syncobj, we do allow userspace to create multiple
sync_files for a single dma-fence. (Similarly, that the sw-sync
validation framework also started returning multiple sync-files wrapping
a single dma-fence for a syncpt also triggering the problem.)

This patch reverts my suggestion in commit e24165537312
("dma-buf/sync_file: only enable fence signalling on poll()") to use a
single bit in the shared dma-fence and restores the sync_file->flags for
tracking the bits individually.

drivers/block/DAC960.c:1681:3: note: 'sprintf' output between 10 and 14 bytes into a destination of size 12

Both of these seem appropriately sized, and using snprintf()
instead of sprintf() improves this by ensuring that even
incorrect data won't cause undefined behavior here.

Subject: v4l: vsp1: Don't recycle active list at display start

When the display start interrupt occurs, we know that the hardware has
finished loading the active display list. The driver then proceeds to
recycle the list, assuming it won't be needed anymore.

This assumption holds true for headerless display lists, as the VSP
doesn't reload the list for the next frame if it hasn't changed.
However, this isn't true anymore for header display lists, as they are
loaded at every frame start regardless of whether they have been
updated.

To prepare for header display lists usage in display pipelines, we need
to postpone recycling the list until it gets replaced by a new one
through a page flip. The driver already does so in the frame end
interrupt handler, so all we need is to skip list recycling in the
display start interrupt handler.

While the active list can be recycled at display start for headerless
display lists, there's no real harm in postponing that to the frame end
interrupt handler in all cases. This simplifies interrupt handling as we
don't need to process the display start interrupt anymore.

Subject: v4l: vsp1: Don't set WPF sink pointer

The sink pointer is used to configure routing inside the VSP, and as
such must point to the next VSP entity in the pipeline. The WPF being a
pipeline terminal sink, its output route can't be configured. The
routing configuration code already handles this correctly without
referring to the sink pointer, which thus doesn't need to be set.

Subject: v4l: vsp1: Store source and sink pointers as vsp1_entity

The internal VSP entity source and sink pointers are stored as
media_entity pointers, which are then cast to a vsp1_entity. As all
sources and sinks are vsp1_entity instances, we can store the
vsp1_entity pointers directly.

Subject: v4l: vsp1: Don't create links for DRM pipeline

When the VSP1 is used in a DRM pipeline the driver doesn't register the
media device. Links between entities are not exposed to userspace, but
are still used internally for the sole purpose of setting up internal
source to sink pointers through the link setup handler.

Instead of going through this complex procedure, remove link creation
and set the sink pointers directly.

In the H3 ES2.0 SoC the VSP2-DL instance has two connections to DU
channels that need to be configured independently. Extend the VSP-DU API
with a pipeline index to identify which pipeline the caller wants to
operate on.

Subject: v4l: vsp1: Add support for the BRS entity

The Blend/ROP Sub Unit (BRS) is a stripped-down version of the BRU found
in several VSP2 instances. Compared to a regular BRU, it supports two
inputs only, and thus has no ROP unit.

Add support for the BRS by modelling it as a new entity type, but reuse
the vsp1_bru object underneath. Chaining the BRU and BRS entities seems
to be supported by the hardware but isn't implemented yet as it isn't
the primary use case for the BRS.

Subject: bnxt_re: add MAY_USE_DEVLINK dependency

bnxt_en depends on MAY_USE_DEVLINK; this is used to force bnxt_en
to be =m when DEVLINK is =m.

Now, bnxt_re selects bnxt_en. Unless bnxt_re also explicitly calls
out dependency on MAY_USE_DEVLINK, Kconfig does not force bnxt_re
to be =m when DEVLINK is =m, causing the following error:

drivers/net/ethernet/broadcom/bnxt/bnxt_vfr.o: In function
`bnxt_dl_register':
bnxt_vfr.c:(.text+0x1440): undefined reference to `devlink_alloc'
bnxt_vfr.c:(.text+0x14c0): undefined reference to `devlink_register'
bnxt_vfr.c:(.text+0x14e0): undefined reference to `devlink_free'
drivers/net/ethernet/broadcom/bnxt/bnxt_vfr.o: In function

bnxt_vfr.c:(.text+0x1534): undefined reference to `devlink_unregister'
bnxt_vfr.c:(.text+0x153c): undefined reference to `devlink_free'

Fix this by adding MAY_USE_DEVLINK dependency in bnxt_re.

Subject: liquidio: bump up driver version to match newer NIC firmware

Bump up driver version to match newer NIC firmware.  Also update
nic_rx_stats (a struct common to host driver and firmware) by adding a new
field:  fw_total_fwd_bytes.

Subject: netvsc: fix warnings reported by lockdep

This includes a bunch of fixups for issues reported by
lockdep.
   * ethtool routines can assume RTNL
   * send is done with RCU lock (and BH disable)
   * avoid refetching internal device struct (netvsc)
     instead pass it as a parameter.

Subject: netvsc: optimize receive completions

Optimize how receive completion ring are managed.
   * Allocate only as many slots as needed for all buffers from host
   * Allocate before setting up sub channel for better error detection
   * Don't need to keep copy of initial receive section message
   * Precompute the watermark for when receive flushing is needed
   * Replace division with conditional test
   * Replace atomic per-device variable with per-channel check.
   * Handle corner case where receive completion send
     fails if ring buffer to host is full.

Subject: netvsc: fix error unwind on device setup failure

If setting receive buffer fails, the error unwind would cause
kernel panic because it was not correctly doing RCU and NAPI
unwind.  RCU'd pointer needs to be reset to NULL, and NAPI needs
to be disabled not deleted.

Subject: iio: bmp280: properly initialize device for humidity reading

If the device is not initialized at least once it happens that the humidity
reading is skipped, which means the special value 0x8000 is delivered.

For omitting this case the oversampling of the humidity must be set before
the oversampling of the temperature und pressure is set as written in the
datasheet of the BME280.

Furthermore proper error detection is added in case a skipped value is read
from the device. This is done also for pressure and temperature reading.
Especially it don't make sense to compensate this value and treat it as
regular value.

Subject: iio: trigger: stm32-timer: fix quadrature mode get routine

Fixes: 4adec7da0536 ("iio: stm32 trigger: Add quadrature encoder device")

SMS bitfiled is mode + 1. After reset, upon boot, SMS = 0. When reading
from sysfs, stm32_get_quadrature_mode() returns -1 (e.g. -EPERM) which is
wrong error code here. So, check SMS bitfiled matches valid encoder mode,
or return -EINVAL.

This fixes two issues:
- stm32_set_count_direction: to set down direction
- stm32_get_count_direction: to get down direction

IIO core provides/expects value to be an index of iio_enum items array.
This needs to be turned by these routines into TIM_CR1_DIR (e.g. BIT(4))
value.
Also, report error when attempting to write direction, when in encoder
mode: in this case, direction is read only (given by encoder inputs).

Subject: iio: trigger: stm32-timer: add enable attribute

In order to use encoder mode, timers needs to be enabled (e.g. CEN bit)
along with peripheral clock.
Add IIO_CHAN_INFO_ENABLE attribute to handle this.
Also, in triggered mode, CEN bit is set automatically in hardware.
Then clock must be enabled before starting triggered mode.

Proper support for the INA219 lowered the minimum sampling period from
2*140us to 2*84us. Subtracting 200us later leads to an underflow and
an almost infinite udelay later.

Using a signed int for the sampling period provides sufficient range
(at most 2*8640*1024us), but catches the underflow when comparing with
buffer_us.

Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared
HCD and set HCD_FLAG_DEAD for it, in analogy with what is done for
the primary one.

Among other thigs, this prevents check_root_hub_suspended() from
returning -EBUSY for dead HCDs which helps to work around system
suspend issues in some situations.

This actually fixes occasional suspend failures on one of my test
machines.

Subject: usb-storage: fix deadlock involving host lock and scsi_done

Christoph Hellwig says that since version 4.12, the kernel switched to
using blk-mq by default.  The old code used a softirq for handling
request completions, but blk-mq can handle completions in the caller's
context.  This may cause a problem for usb-storage, because it invokes
the ->scsi_done callback while holding the host lock, and the
completion routine sometimes tries to acquire the same lock (when
running the error handler, for example).

The consequence is that the existing code will sometimes deadlock upon
error completion of a SCSI command (with a lockdep warning).

This is easy enough to fix, since usb-storage doesn't really need to
hold the host lock while the callback runs.  It was simpler to write
it that way, but moving the call outside the locked region is pretty
easy and there's no downside.  That's what this patch does.

Subject: usb: core: unlink urbs from the tail of the endpoint's urb_list

While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.

Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.

This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

Subject: usb: musb: fix tx fifo flush handling again

commit 68fe05e2a451 ("usb: musb: fix tx fifo flush handling") drops the
1ms delay trying to solve the long disconnect time issue when
application queued many tx urbs. However, the 1ms delay is needed for
some use cases, for example, without the delay, reconnecting AR9271 WIFI
dongle no longer works if the connection is dropped from the AP.

So let's add back the 1ms delay in musb_h_tx_flush_fifo(), and solve the
long disconnect time problem with a separate patch for
usb_hcd_flush_endpoint().

Subject: usb: mtu3: handle delayed status of the control transfer

Add the delayed status handling. This is used by mass storage etc to
gain some extra time to setup its internal status before it can proceed
further requests, and once the gadget is ready, it will enqueue an
empty packet which is used for synchronization.
The issue may happen on some FGPA platform with very low cpu frequency.

Subject: isp116x-hcd: constify hc_driver structures

The hc_driver structure is only passed as the first argument to
usb_create_hcd, which is declared as const.  Thus the hc_driver structure
itself can be const.

Done with the help of Coccinelle.

Subject: tty: serial: pci: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

Subject: tty: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: serial: 8250_dw: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: serial: imx: drop useless member from driver data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The wait queue was only initialized and then checked if it contains
active jobs but a job is never added. The last real user was removed
with commit 9d297239b8cb ("serial: imx-serial - update UART IMX driver
to use cyclic DMA").

Further there is no need to release the lock for the check if the port
should be woken up, (and IMHO there never was) so drop the unlock/lock
pair in dma_tx_callback(), too.

Subject: serial: sprd: clear timeout interrupt only rather than all interrupts

On Spreadtrum's serial device, nearly all of interrupts would be cleared
by hardware except timeout interrupt.  This patch removed the operation
of clearing all interrupt in irq handler, instead added an if statement
to check if the timeout interrupt is supposed to be cleared.

Wrongly clearing timeout interrupt would lead to uart data stay in rx
fifo, that means the driver cannot read them out anymore.

Enforce corresponding types when upf_t being assigned.

First 16 bits in the flags field are user-visible except
UPF_NO_TXEN_TEST. To keep it clean we introduce internal quirks and move
UPF_NO_TXEN_TEST to them. Rename the constant to UPQ_NO_TXEN_TEST to
distinguish with port flags. Users are converted accordingly.

The quirks field might be extended later to hold the additional ones.

Subject: serial: 8250_pci: Enable device after we check black list

If the board we are guessing has been listed in black list we don't need
to enable it twice. The associated driver, if any, will take care about
proper initialization.

To achieve this we split out two helper functions, i.e.
serial_pci_is_class_communication() and serial_pci_is_blacklisted() which will
be called before pcim_enable_device(). We can do this since PCI specification
requires class, device and vendor ID registers to be always present in the
configuration space.

As an example what happens before this patch applied
(These are some debug prints, don't search for them in kernel sources):

	serial 0000:00:04.1: Mapped GSI28 to IRQ28
	serial 0000:00:04.2: Mapped GSI29 to IRQ29
	serial 0000:00:04.3: Mapped GSI54 to IRQ54
	8250_mid 0000:00:04.1: Mapped GSI28 to IRQ28
	8250_mid 0000:00:04.2: Mapped GSI29 to IRQ29
	8250_mid 0000:00:04.3: Mapped GSI54 to IRQ54

After we will have just last three lines out of above.

	8250_mid 0000:00:04.1: Mapped GSI28 to IRQ28
	8250_mid 0000:00:04.2: Mapped GSI29 to IRQ29
	8250_mid 0000:00:04.3: Mapped GSI54 to IRQ54

While here, correct a value of error code mentioned in the comment of
serial_pci_guess_board().

Subject: tty: improve tty_insert_flip_char() fast path

kernelci.org reports a crazy stack usage for the VT code when CONFIG_KASAN
is enabled:

drivers/tty/vt/keyboard.c: In function 'kbd_keycode':
drivers/tty/vt/keyboard.c:1452:1: error: the frame size of 2240 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

The problem is that tty_insert_flip_char() gets inlined many times into
kbd_keycode(), and also into other functions, and each copy requires 128
bytes for stack redzone to check for a possible out-of-bounds access on
the 'ch' and 'flags' arguments that are passed into
tty_insert_flip_string_flags as a variable-length string.

This introduces a new __tty_insert_flip_char() function for the slow
path, which receives the two arguments by value. This completely avoids
the problem and the stack usage goes back down to around 100 bytes.

Without KASAN, this is also slightly better, as we don't have to
spill the arguments to the stack but can simply pass 'ch' and 'flag'
in registers, saving a few bytes in .text for each call site.

This should be backported to linux-4.0 or later, which first introduced
the stack sanitizer in the kernel.

Subject: tty: improve tty_insert_flip_char() slow path

While working on improving the fast path of tty_insert_flip_char(),
I noticed that by calling tty_buffer_request_room(), we needlessly
move to the separate flag buffer mode for the tty, even when all
characters use TTY_NORMAL as the flag.

This changes the code to call __tty_buffer_request_room() with the
correct flag, which will then allocate a regular buffer when it rounds
out of space but no special flags have been used. I'm guessing that
this is the behavior that Peter Hurley intended when he introduced
the compacted flip buffers.

Subject: tty: pl011: fix initialization order of QDF2400 E44

The work-around for Qualcomm Technologies QDF2400 Erratum 44 hinges on a
global variable defined in the pl011 driver.  The ACPI SPCR parsing code
determines whether the work-around is needed, and if so, it changes the
console name from "pl011" to "qdf2400_e44".  The expectation is that
the pl011 driver will implement the work-around when it sees the console
name.  The global variable qdf2400_e44_present is set when that happens.

The problem is that work-around needs to be enabled when the pl011
driver probes, not when the console name is queried.  However, sbsa_probe()
is called before pl011_console_match().  The work-around appeared to work
previously because the default console on QDF2400 platforms was always
ttyAMA1.  The first time sbsa_probe() is called (for ttyAMA0),
qdf2400_e44_present is still false.  Then pl011_console_match() is called,
and it sets qdf2400_e44_present to true.  All subsequent calls to
sbsa_probe() enable the work-around.

The solution is to move the global variable into spcr.c and let the
pl011 driver query it during probe time.  This works because all QDF2400
platforms require SPCR, so parse_spcr() will always be called.
pl011_console_match still checks for the "qdf2400_e44" console name,
but it doesn't do anything else special.

Subject: greybus: usb: constify hc_driver structures

The hc_driver structure is only passed as the first argument to
usb_create_hcd, which is declared as const.  Thus the hc_driver structure
itself can be const.

Done with the help of Coccinelle.

Subject: staging: lustre: lov: use u64 instead of loff_t in
 lov_object_fiemap()

Change loff_t to u64 in lov_object_fiemap() since loff_t is a signed
value type.

Otherwise there could be an overflow in
drivers/staging/lustre/lustre/lov/lov_object.c:1241 lov_object_fiemap()
warn: signed overflow undefined. 'fm_start + fm_length < fm_start'

Subject: staging: lustre: osc: soft lock - osc_makes_rpc()

It is possible that an osc_extent contains more than 256 chunks, and
the IO engine won't add this extent in one RPC
(try_to_add_extent_for_io) so that osc_check_rpcs() run into a loop
upon this extent and never break.

This patch changes osc_max_write_chunks() to make sure the value
can cover all possible osc_extent, so that all osc_extent will be
added into one RPC.

This patch also add another field erd_max_extents in extent_rpc_data
to make sure not to add too many fragments in a single RPC.

Date: Wed, 26 Jul 2017 11:22:21 -0400
Subject: staging: lustre: lov: remove unused code

Remove:
  the tested but never set flag OBD_STATFS_PTLRPCD,
  the empty file lustre/lov/lovsub_io.c,
  the unused ld_emerg member of struct lov_device,
  the unused struct lov_device_emerg and supporting functions,
  the unused struct lov_lock_link and supporting functions, and
  the unused, get only, or set only members of struct
  lovsub_device, lovsub_lock, lov_sublock_env, lov_thread_info,
  lov_io_sub, lov_io, lov_request, and lov_request_set.
Reduce the scope of several functions from lov_request.c.

From fc153de17ac426a47b5e19bb4f911137a12b89fd Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Wed, 26 Jul 2017 11:22:22 -0400
Subject: staging: lustre: lmv: assume a real connection in lmv_connect()

Assume a real connection in lmv_connect(). Mark OBD_CONNECT_REAL
obsolete. Remove the then unnecessary refcount and exp members of
struct lmv_obd. Remove calls to lmv_check_connect(). Disconnect the
export in the appropriate error path of lmv_connect().

Subject: staging: lustre: lov: Ensure correct operation for large object sizes

If a backing filesystem (ZFS) returns that it supports very large
(LLONG_MAX) object sizes, that should be correctly supported.  This
fixes the check for unitialized stripe_maxbytes in
lsm_unpackmd_common(), so that ZFS can return LLONG_MAX and it will be
okay. This issue is excersized by writing to or past the 2TB boundry
of a singly stripped file.

Subject: staging: lustre: ptlrpc: correct use of list_add_tail()

With people starting to test security enabled ptlrpc
a list_del corruption was reported. The reason for
this error was tracked down to wrong arguments to
list_add_tail(). In sptlrpc_gc_add_sec() swap the
arguments to list_add_tail() so that it does what
we meant it to do.

Subject: staging: lustre: ptlrpc: no need to reassign mbits for replay

It's not necessary reassgin & re-adjust rq_mbits for replay
request in ptlrpc_set_bulk_mbits(), they all must have already
been correctly assigned before.

Such unecessary reassign could make the first matchbit not
PTLRPC_BULK_OPS_MASK aligned, that'll trigger LASSERT in
ptlrpc_register_bulk():

- ptlrpc_set_bulk_mbits() is called when first time sending
  request, rq_mbits is set as xid, which is BULK_OPS aligned;

- ptlrpc_set_bulk_mbits() continue to adjust the mbits for
  multi-bulk RPC, rq_mbits is not aligned anymore, then rq_xid
  is changed accordingly if client is connecting to an old
  server, so rq_xid became unaligned too;

- The request is replayed, ptlrpc_set_bulk_mbits() reassign
  the rq_mbits as rq_xid, which isn't aligned already, but
  ptlrpc_register_bulk() still assumes this value as the
  first matchbits and LASSERT it's BULK_OPS aligned.

Subject: staging: lustre: linkea: linkEA size limitation

Under DNE mode, if we do not restrict the linkEA size, and if there
are too many cross-MDTs hard links to the same object, then it will
cause the llog overflow. On the other hand, too many linkEA entries
in the linkEA will serious affect the linkEA performance because we
only support to locate linkEA entry consecutively.

So we need to restrict the linkEA size. Currently, it is 4096 bytes,
that is independent from the backend. If too many hard links caused
the linkEA overflowed, we will add overflow timestamp in the linkEA
header.

Subject: staging: lustre: ptlrpc: restore 64-bit time for struct
 ptlrpc_cli_req

During the reorganization of ptlrpc_request some of the
time64_t fields were incorrectly turned into time_t.
Restore those fields back to time_64_t.

The libcfs CFS_DURATION_T define is really only for

replaced it with normal %lld instead.

correct size to compare against is struct libcfs_ioctl_hdr.

Move the freeing of all cached acls from ll_get_acl() to the

for the inode just before clearing it. This allow us to take
advantage of cached acls and correctly free them before free.

Subject: staging: lustre: llite: set security xattr using __vfs_setxattr

Currently ll_initxattrs() initializes the security xattrs in
a very non-standard using get_xattr_types() to get the struct
handler that lustre created to then call indirectly the function
to set the xattr. The available __vfs_setxattr() function does
the same thing and also handles the case of when size is zero
the xattr should be set to empty EA.

of %llx. This fixes these warnings on 32 bit targets:
 "format '%llx' expects argument of type 'long long unsigned int',
  but argument 4 has type 'phys_addr_t' [-Wformat=]"

Subject: staging: fsl-mc: don't use raw device io functions

As raw device io functions are not portable and don't handle byte-order
(triggering suspicion that endianness isn't handled well) switch to
using the standard api.
Since MC expects LE byte-order and the upper layers already take care
of that, we need to trick the device io api by doing a LE -> CPU
conversion just before calling it. This way, the CPU -> LE conversion
done in the api puts the data back in the right byte-order. Obviously,
for reads the extra step is mirrored: there's a CPU -> LE conversion
following the API call.

Subject: staging: fsl-mc: make the driver compile on 32-bit

Since there's no real constrain in MC to do only atomic 64-bit we can
enable this driver on 32-bit platforms too.
Include linux/io-64-nonatomic-hi-lo.h to make quad device io apis used
in the driver available on 32-bit platforms.

Subject: staging: fsl-mc: allow the driver compile multi-arch

Add an alternate dependency on COMPILE_TEST, thus leaving
this driver compile on other architectures.
Also, other drivers depending on the bus are updated to depend
on ARCH_LAYERSCAPE until they'll also be made multi-arch.
This was compiled tested on:
 - booke powerpc (corenet{32,64}_smp_defconfig)
 - x86 (i386_defconfig, x86_64_defconfig, needs CONFIG_OF)
 - arm64 (defconfig)

Subject: staging: nvec: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: staging: bcm2835-audio: constify snd_pcm_ops structures

Check for snd_pcm_ops structures that are only stored in the ops field of
a snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops. The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as
const also.

This issue was detected using Coccinelle and the following semantic patch:

static struct snd_pcm_ops i@p = { ... };

Subject: staging: wlan-ng: Fix the types of the hfa384x_comm_tallies_16/32
 members

Running sparse revealed that the members of hfa384x_comm_tallies_16/32
were defined as u16/u32, but were actually used as __le16/__le32.

This patch changes the member types to reflect their use.

Subject: staging: comedi: comedi_fops: do not call blocking ops when
 !TASK_RUNNING

Comedi's read and write file operation handlers (`comedi_read()` and
`comedi_write()`) currently call `copy_to_user()` or `copy_from_user()`
whilst in the `TASK_INTERRUPTIBLE` state, which falls foul of the
`might_fault()` checks when enabled.  Fix it by setting the current task
state back to `TASK_RUNNING` a bit earlier before calling these
functions.

Subject: iio: adc: stm32: fix common clock rate

ADC clock input is provided to internal prescaler (that decreases its
frequency). It's then used as reference clock for conversions.

- Fix common clock rate used then by stm32-adc sub-devices. Take common
  prescaler into account. Currently, rate is used to set "boost" mode.
  It may unnecessarily be set. This impacts power consumption.
- Fix ADC max clock rate on STM32H7 (fADC from datasheet). Currently,
  prescaler may be set too low. This can result in ADC reference
  clock used for conversion to exceed max allowed clock frequency.

Subject: tcmu: Fix possible to/from address overflow when doing the memcpy

For most case the sg->length equals to PAGE_SIZE, so this bug won't
be triggered. Otherwise this will crash the kernel, for example when
all segments' sg->length equal to 1K.

Commit 8b44f5be20fd ("ARM: dts: armada: replace isil,irq2-can-wakeup-machine with wakeup-source property")
removed the last usage of "isil,irq2-can-wakeup-machine" almost
two years ago. So I think we can get rid of supporting this
legacy binding.

Subject: tcmu: free old string on reconfig

On initial tcmu_configure_device call the info->name would
have already been allocated and set, so on the second call
make sure to free it first.

Subject: iscsi-target: fix memory leak in iscsit_setup_text_cmd()

On receiving text request iscsi-target allocates buffer for
payload in iscsit_handle_text_cmd() and assigns buffer pointer
to cmd->text_in_ptr, this buffer is currently freed in
iscsit_release_cmd(), if iscsi-target sets 'C' bit in text
response then it will receive another text request from the
initiator with ttt != 0xffffffff in this case iscsi-target
will find cmd using itt and call iscsit_setup_text_cmd()
which will set cmd->text_in_ptr to NULL without freeing
previously allocated buffer.

This patch fixes this issue by calling kfree(cmd->text_in_ptr)
in iscsit_setup_text_cmd() before assigning NULL to it.

For the first text request cmd->text_in_ptr is NULL as
cmd is memset to 0 in iscsit_allocate_cmd().

Subject: iscsi-target: fix invalid flags in text response

In case of multiple text responses iscsi-target
sets both 'F' and 'C' bit for the final text response
pdu, this issue happens because hdr->flags is not
zeroed out before ORing with 'F' bit.

This patch removes the | operator to fix this issue.

Subject: cxgbit: fix sg_nents calculation

The current logic of calculating sg_nents can fail
if data_offset % PAGE_SIZE is not zero.

For example -
PAGE_SIZE = 4096
data_len = 3072
data_offset = 3072

As per current logic
sg_nents = max(1UL, DIV_ROUND_UP(data_len, PAGE_SIZE));
sg_nents = max(1UL, DIV_ROUND_UP(3072, 4096));
sg_nents = 1

But as data_offset % PAGE_SIZE = 3072 we should skip 3072 bytes
skip = 3K
sg_nents = max(1UL, DIV_ROUND_UP(3K(skip) + 3K(data_len), 4K(PAGE_SIZE));
sg_nents = 2;

This patch fixes this issue by adding skip to data_len.

Subject: qla2xxx: Fix incorrect tcm_qla2xxx_free_cmd use during TMR ABORT (v2)

This patch drops two incorrect usages of tcm_qla2xxx_free_cmd()
during TMR ABORT within tcm_qla2xxx_handle_data_work() and
tcm_qla2xxx_aborted_task(), which where attempting to dispatch
into workqueue context to do tcm_qla2xxx_complete_free() and
subsequently invoke transport_generic_free_cmd().

This is incorrect because during TMR ABORT target-core will
drop the outstanding se_cmd->cmd_kref references once it has
quiesced the se_cmd via transport_wait_for_tasks(), and in
the case of qla2xxx it should not attempt to do it's own
transport_generic_free_cmd() once the abort has occured.

As reported by Pascal, this was originally manifesting as a
BUG_ON(cmd->cmd_in_wq) in qlt_free_cmd() during TMR ABORT,
with a LIO backend that had sufficently high enough WRITE
latency to trigger a host side TMR ABORT_TASK.

(v2: Drop the qla_tgt_cmd->write_pending_abort_comp changes,
     as they will be addressed in a seperate series)

At present we are using init_table to initialize some
registers, but the Register init table use un-document define,
it is unreadable, and sometimes we only want to update tiny
bits, init table method is not friendly, it's diffcult to
reuse for difference chips.

To make it clean, initialize registers directly, and drops
init_table mechanism out.

Subject: drm/rockchip: vop: move write_relaxed flags to vop register

Since the drm atomic framework, only a small part of the vop
register needs sync write, Currently seems only following registers
need sync write:
   cfg_done, standby and interrupt related register.

All ctrl registers are using the sync write method that is
inefficient, hardcode the write_relaxed flags to vop registers,
then can only do synchronize write for those actual needed register.

Subject: drm/rockchip: vop: move line_flag_num to interrupt registers

In the hardware design process, the design of line flags
register is associated with the interrupt register,
placing the line flags in the interrupt definition is
more reasonable, and it would make multi-vop define easilier.

Subject: drm/rockchip: vop: add a series of vop support

Vop Full framework now has following vops:
IP version    chipname
  3.1           rk3288
  3.2           rk3368
  3.4           rk3366
  3.5           rk3399 big
  3.6           rk3399 lit
  3.7           rk3228
  3.8           rk3328

The above IP version is from H/W define, some of vop support get
the IP version from VERSION_INFO register, some are not.
hardcode the IP version for each vop to identify them.

major version: used for IP structure, Vop full framework is 3,
               vop little framework is 2.
minor version: on same structure, newer design vop will bigger
               then old one.

Subject: drm/rockchip: vop: rk3328: fix overlay abnormal

It's a hardware bug, all window's overlay channel reset
value is same, hardware overlay would be die.

so we must initial difference id for each overlay channel.

The Channel register is supported on all vop will full design.
Following is the details for this register
VOP_WIN0_CTRL2
  bit[7:4] win_rid_win0_cbr
       axi read id of win0 cbr channel
  bit[3:0] win_rid_win0_yrgb
       axi read id of win0 yrgb channel

Preparing for the following fix of MDIO phy access:

Renamed functions that access PHY 1 and 2 indirectly through PMI
registers.

 lan9303_port_phy_reg_wait_for_completion() to
 lan9303_indirect_phy_wait_for_completion()

 lan9303_port_phy_reg_read() to
 lan9303_indirect_phy_read()

 lan9303_port_phy_reg_write() to
 lan9303_indirect_phy_write()

Also changed "val" parameter of lan9303_indirect_phy_write() to u16,
for clarity.

Indirect access (PMI) to phy register only work in I2C mode. In
MDIO mode phy registers must be accessed directly. Introduced
struct lan9303_phy_ops to handle the two modes.

If the PHY is missing but expected, e.g. because of a typ0 in the dt
file, it is not possible to open the interface. ip link returns:

RTNETLINK answers: No such device

It is not very obvious what the problem is. Add a netdev_err() in this
case to make it easier to debug the issue.

Subject: net: fec: Allow reception of frames bigger than 1522 bytes

The FEC Receive Control Register has a 14 bit field indicating the
longest frame that may be received. It is being set to 1522. Frames
longer than this are discarded, but counted as being in error.

When using DSA, frames from the switch has an additional header,
either 4 or 8 bytes if a Marvell switch is used. Thus a full MTU frame
of 1522 bytes received by the switch on a port becomes 1530 bytes when
passed to the host via the FEC interface.

Change the maximum receive size to 2048 - 64, where 64 is the maximum
rx_alignment applied on the receive buffer for AVB capable FEC
cores. Use this value also for the maximum receive buffer size. The
driver is already allocating a receive SKB of 2048 bytes, so this
change should not have any significant effects.

Tested on imx51, imx6, vf610.

Subject: powerpc/udbg: Reduce the footgun potential of EARLY_DEBUG_LPAR(_HVSI)

For debugging very early boot problems we have CONFIG_PPC_EARLY_DEBUG,
which allows configuring the kernel such that it unconditionally writes
to a particular type of console, regardless of whether that console
exists or not. This is useful sometimes when the kernel crashes before
it can even determine what platform it's on, and therefore what consoles
exist.

However if you boot a kernel built this way on a different platform, it
will generally crash because it writes to a console that doesn't exist.

A particularly nasty instance of this is if you enable the hypervisor
console early debug, and then boot that kernel on bare metal. The result
is that the kernel calls "the hypervisor" very early in boot, but the
kernel *is* the hypervisor, so we jump to the system call handler and
start executing all sorts of code that isn't ready to be run. This may
lead to a machine check or check stop depending on how lucky you are.

Luckily there is an easy way to avoid this particular case. We simply
read the MSR before installing the hooks, and if we see MSR_HV is set
then we are the hypervisor and we definitely should not use the
hypervisor console.

(It's not very apparent from the OF documentation that of_node_put() is
not needed; the macro itself has no docstring and of_get_next_child()
used in the implementation begins with "Returns a node pointer with
refcount incremented" but then only at the very end of the docstring
the crucial part "Decrements the refcount of prev" is mentioned.)

  185: USB2OD
  186: USB2ID
  187: USB3VBUS
  188: USB3OD

USB#2 has an additional pin "USB2ID", but the chip doesn't use this pin
while in host-mode. Considering this pin, the pin definitions for USB#3
should be {187, 188}.

Subject: i2c: core: Allow empty id_table in ACPI case as well

For now empty ID table is not allowed with ACPI and prevents driver to
be probed.

Add a check to allow empty ID table.

This introduces a helper i2c_acpi_match_device().

Note, we rename some static function in i2c-core-acpi.c to distinguish
with public API.

Subject: pinctrl: sunxi: add a missing function of A10/A20 pinctrl driver

The PH16 pin has a function with mux id 0x5, which is the DET pin of the
"sim" (smart card reader) IP block.

This function is missing in old versions of A10/A20 SoCs' datasheets and
user manuals, so it's also missing in the old drivers. The newest A10
Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and
it's discovered during implementing R40 pinctrl driver.

Add it to the driver. As we now merged A20 pinctrl driver to the A10
one, we need to only fix the A10 driver now.

Subject: dma-buf/sync_file: Allow multiple sync_files to wrap a single
 dma-fence

Up until recently sync_file were create to export a single dma-fence to
userspace, and so we could canabalise a bit insie dma-fence to mark
whether or not we had enable polling for the sync_file itself. However,
with the advent of syncobj, we do allow userspace to create multiple
sync_files for a single dma-fence. (Similarly, that the sw-sync
validation framework also started returning multiple sync-files wrapping
a single dma-fence for a syncpt also triggering the problem.)

This patch reverts my suggestion in commit e24165537312
("dma-buf/sync_file: only enable fence signalling on poll()") to use a
single bit in the shared dma-fence and restores the sync_file->flags for
tracking the bits individually.

Subject: i2c: designware: Some broken DSTDs use 1MiHz instead of 1MHz

At least the Acer Iconia Tab8 / aka W1-810 uses 1MiHz instead of
1MHz for one of its busses, fix this up to 1MHz instead of failing
the probe of that bus.

This fixes the accelerometer on the Acer Iconia Tab8 not working.

Subject: i2c: mediatek: send i2c master code at 400k

The speed of sending i2c master code in high-speed mode depends on
source clock, clock-div and TIMING register. The source clock and
clock-div of different SoC are not all the same. In order to send
i2c master code at 400k in high-speed mode, a appropriate value
should be set to TIMING register for a certain source clock and
clock-div.

Subject: i2c: use dev_get_drvdata() to get private data in suspend/resume
 hooks

Several drivers call to_platform_device() to get platform_device
and pass it to platform_get_drvdata().  In platform_get_drvdata(),
the platform_device is converted back to struct device again.

Use dev_get_drvdata() to avoid platform_device/device dance.

We free "info" then dereference it on the next line.  Really this whole

things are allocated in the probe.

Subject: efifb: allow user to disable write combined mapping.

This patch allows the user to disable write combined mapping
of the efifb framebuffer console using an nowc option.

A customer noticed major slowdowns while logging to the console
with write combining enabled, on other tasks running on the same
CPU. (10x or greater slow down on all other cores on the same CPU
as is doing the logging).

I reproduced this on a machine with dual CPUs.
Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz (6 core)

I wrote a test that just mmaps the pci bar and writes to it in
a loop, while this was running in the background one a single
core with (taskset -c 1), building a kernel up to init/version.o
(taskset -c 8) went from 13s to 133s or so. I've yet to explain
why this occurs or what is going wrong I haven't managed to find
a perf command that in any way gives insight into this.

    11,885,070,715      instructions              #    1.39  insns per cycle
vs
    12,082,592,342      instructions              #    0.13  insns per cycle

is the only thing I've spotted of interest, I've tried at least:
dTLB-stores,dTLB-store-misses,L1-dcache-stores,LLC-store,LLC-store-misses,LLC-load-misses,LLC-loads,\mem-loads,mem-stores,iTLB-loads,iTLB-load-misses,cache-references,cache-misses

For now it seems at least a good idea to allow a user to disable write
combining if they see this until we can figure it out.

Note also most users get a real framebuffer driver loaded when kms
kicks in, it just happens on these machines the kernel didn't support
the gpu specific driver.

Subject: dma-buf/sw_sync: clean up list before signaling the fence

If userspace already dropped its own reference by closing the sw_sync
fence fd we might end up in a deadlock where
dma_fence_is_signaled_locked() will trigger the release of the fence and
thus try to hold the lock to remove the fence from the list.

dma_fence_is_signaled_locked() tries to release/free the fence and hold
the lock in the process.

We fix that by changing the order operation and clean up the list and
rb-tree first.

v2: Drop fence get/put dance and manipulate the list first (Chris Wilson)

Subject: IB/hns: include linux/interrupt.h

I ran into this build error on linux-next:

drivers/infiniband/hw/hns/hns_roce_eq.c:477:8: error: unknown type name 'irqreturn_t'
 static irqreturn_t hns_roce_msi_x_interrupt(int irq, void *eq_ptr)
        ^~~~~~~~~~~
drivers/infiniband/hw/hns/hns_roce_eq.c: In function 'hns_roce_msi_x_interrupt':
drivers/infiniband/hw/hns/hns_roce_eq.c:485:9: error: implicit declaration of function 'IRQ_RETVAL'; did you mean 'BPF_RVAL'? [-Werror=implicit-function-declaration]
  return IRQ_RETVAL(int_work);

I have bisected this to a seemingly unrelated change that happened
to remove some indirect header inclusions. Simply including the
required header explicitly fixes the build failure.

Subject: IB/hfi1: Fix bar0 mapping to use write combining

When the debugpat kernel boot flag is turned on the following
traces are printed:

[ 1884.793168] x86/PAT: Overlap at 0x90000000-0x92000000
[ 1884.803510] x86/PAT: reserve_memtype added [mem 0x91200000-0x9127ffff],
track uncached-minus, req write-combining, ret uncached-minus
[ 1884.818167] hfi1 0000:05:00.0: hfi1_0: WC Remapped RcvArray:
ffffc9000a980000

The ioremap_wc() clearly is not returning a write combining mapping due
to an overlap where the RcvArray is mapped in a uncached mapping prior
to creating the proposed write combining mapping.

The patch replaces the single base register for uncached CSRs that
used to overlap the RcvArray with two mappings.   One, kregbase1, from the
bar0 up to the RcvArray and another, kregbase2, from the end of the
RcvArray to the pio send buffer space.  A new dd field, base2_start,
is used to convert the zero-based offset in the CSR routines to the
correct kregbase1/kregbase2 mapping.  A single direct write of the
RcvArray CSRs is replaced with hfi1_put_tid() to insure correct access
using the new disjoint mapping.

Additionally, the kregend field is deleted since it is only ever written.

patdebug now shows the RcvArray as write combining:
[   35.688990] x86/PAT: reserve_memtype added [mem 0x91200000-0x9127ffff],
track write-combining, req write-combining, ret write-combining

To insulate from any potential issues with write combining, all
writeq are now flushed in hfi1_put_tid() and rcv_array_wc_fill().

Subject: IB/hfi1: Serve the most starved iowait entry first

When an egress resource(SDMA descriptors, pio credits) is not available,
a sending thread will be put on the resource's wait queue. When the
resource becomes available again, up to a fixed number of sending threads
can be awakened sequentially and removed from the wait queue, depending
on the number of waiting threads and the number of free resources. Since
each awakened sending thread will send as many packets as possible, it
is highly likely that the first sending thread will consume all the
egress resources. Subsequently, it will be put back to the end of the wait
queue. Depending on the timing when the later sending threads wake up,
they may not be able to send any packet and be again put back to the end
of the wait queue sequentially, right behind the first sending thread.
This starvation cycle continues until some sending threads exceed their
retry limit and consequently fail.

This patch fixes the issue by two simple approaches:
(1) Any starved sending thread will be put to the head of the wait queue
while a served sending thread will be put to the tail;
(2) The most starved sending thread will be served first.

From 42492011ab23f44c63dad0c7096492313dc207e3 Mon Sep 17 00:00:00 2001
From: "Michael J. Ruhl" <michael.j.ruhl@intel.com>
Date: Mon, 24 Jul 2017 07:45:43 -0700
Subject: IB/hfi1: Assign context does not clean up file descriptor correctly
 on error

In the error path for context allocation, the file descriptor pointer
should not point to a context when an error occurs.

Clean up the appropriate references on error.

Fixes: Commit 62239fc6e5545b2e59f83dfbc5db231a81f37a45 ("IB/hfi1: Clean up on context initialization failure")

Subject: IB/hfi1: Size rcd array index correctly and consistently

The array index for the rcd array is sized several different ways
throughout the code.

Use the user interface size (u16) as the standard size and update the
necessary code to reflect this.

u16 is large enough for the largest amount of supported contexts.

Subject: IB/hfi1: Use context pointer rather than context index

The hfi1_<set|clear>_ctxt_<j|p>key functions take a context index and
look up the context based on that index.

Since the context index is being retrieved from the context, this
doesn't seem optimal.

Pass the context pointer for use, rather than the context index.

Subject: IB/hfi1: Pass the context pointer rather than the index

The hfi1_rcvctrl() function receives an index which it then converts
to an rcd.  Since most functions have the rcd, use that instead.

Subject: IB/hfi1: Send MAD traps until repressed

A trap should be sent to the FM until the FM sends a repress message.
This is in line with the IBTA 13.4.9.

Add the ability to resend traps until a repress message is received.

Subject: IB/hfi1: Fix code consistency for if/else blocks in chip.c

Code structure is not consistent for if/else blocks and break
instructions in set_link_state for case HLS_UP_INIT. Physical
state uses break in case of an error and if/else blocks for
logical use cases. These blocks should be implemented consistently.

Subject: IB/hfi1: Move saving PCI values to a separate function

During PCIe initialization some registers' values from
PCI config space are saved in order to restore them later
(i.e. after reset). Restoring those value is done by a
function called restore_pci_variables, while saving them
is put directly into function hfi1_pcie_ddinit.
Move saving values to a separate function in the image
of restoring functionality.

Subject: IB/hfi1: Verify port data VLs credits on transition to Armed

There is a window where the FM can read the buffer control table
and decide not to program buffers. When a port goes down, the code
clears the table and if it is not programmed, posted SDMA descriptors
will never complete due to no buffer credits.

Subject: IB/hfi1: Harden state transition to Armed and Active

There is a window that allows other threads to read state of
'host_link_state' as a new, before the hardware actual state is set.
This patch closes the window by indicating a new state only after
hardware transition is complete.

Subject: IB/hfi1: Only set fd pointer when base context is completely
 initialized

The allocate_ctxt() function adds the context to the fd data structure.
Since the context is not completely initialized, this can cause confusion
as to whether the context is valid or not.

Move the fd reference from allocate_ctxt() to setup_base_ctxt().
Update the necessary functions to be aware of this move.

The root cause is that the qib/hfi1 post receive call to rvt_lkey_ok()
doesn't interpret the new return value from rvt_lkey_ok() properly
leading to an mr reference count underrun.

Additionally, remove an unused argument in rvt_sge_adjacent()
aw well as an unneeded incr local in rvt_post_one_wr().

Subject: IB/hfi1: Prevent link down request double queuing

When link interrupts occur, multiple link down requests
could be queued up when only one is needed. This could get
the hfi1 out of sync with its link partner during LNI.

Only allow one link down request to be queued at any one time.

Subject: IB/hfi1: Always perform offline transition

Always initiate an offline transition request
when a link down occurs. The firmware will
use this request to confirm that the driver
has seen the link down message. A host version
is set to indicate this driver behavior to the
firmware.

Subject: PCI: Mark Broadcom HT2100 Root Port Extended Tags as broken

Per PCIe r3.1, sec 2.2.6.2 and 7.8.4, a Requester may not use 8-bit Tags
unless its Extended Tag Field Enable is set, but all Receivers/Completers
must handle 8-bit Tags correctly regardless of their Extended Tag Field
Enable.

Some devices do not handle 8-bit Tags as Completers, so add a quirk for
them.  If we find such a device, we disable Extended Tags for the entire
hierarchy to make peer-to-peer DMA possible.

The Broadcom HT2100 seems to have issues with handling 8-bit tags.  Mark it
as broken.

The pci_walk_bus() in the quirk handles devices we've enumerated in the
past, and pci_configure_device() handles devices we enumerate in the
future.

Fixes: 60db3a4d8cc9 ("PCI: Enable PCIe Extended Tags if supported")

Subject: PCI: Mark AMD Stoney GPU ATS as broken

ATS is broken on this hardware and causes IOMMU stalls and system failure.
Disable ATS on these devices to make them usable again with IOMMU enabled.

Note that the commit in the Fixes tag is not buggy; it just uncovers the
problem in the hardware by increasing the ATS flush rate.

Subject: net: phy: mdio-bcm-unimac: create unique bus names

In preparation for having multiple GENET instances in a system (up to
3), make sure that we do include the bus instance number in the name of
the MDIO bus such that we change it from "unimac-mdio" to
"unimac-mdio-0" for instance.

So far, the only user of this driver is using Device Tree, which uses a
lookup/parenting based technique to map PHY devices to their respective
MDIO bus controllers, hence causing no additional changes.

In preparation for having the bcmgenet driver migrate over the
mdio-bcm-unimac driver, add a platform data structure which allows
passing integrating specific details like bus name, wait function to
complete MDIO operations and PHY mask.

We also define what the platform device name contract is by defining
UNIMAC_MDIO_DRV_NAME and moving it to the platform_data header.

Subject: net: bcmgenet: utilize generic Broadcom UniMAC MDIO controller driver

Update the GENET driver to register an UniMAC MDIO bus controller for
the GENET internal MDIO bus, update the platform data code to attach the
PHY to the correct MDIO bus controller.

The Device Tree portion of the code is mostly left unmodified since the
lookup/binding is done via phandles and Device Tree nodes which are much
more flexible in locating and binding PHYs to their respective MDIO bus
controllers.

Subject: net: bcmgenet: Utilize bcmgenet_mii_exit() for error path

bcmgenet_mii_init() has an error path which is strictly identical to the
unwinding that bcmgenet_mii_exit() does, so have bcmgenet_mii_init()
utilize bcmgenet_mii_exit() for that.

Subject: net: bcmgenet: Add dependency on HAS_IOMEM && OF

The driver needs CONFIG_HAS_IOMEM and OF to be functional, but we still
let it build with COMPILE_TEST. This fixes the unmet dependency after
selecting MDIO_BCM_UNIMAC in commit mentioned below:

warning: (NET_DSA_BCM_SF2 && BCMGENET) selects MDIO_BCM_UNIMAC which has
unmet direct dependencies (NETDEVICES && MDIO_DEVICE && HAS_IOMEM &&
OF_MDIO)

Turns out that MII_M1116R_CONTROL_REG_MAC is the same as
MII_88E1121_PHY_MSCR_REG. Refactor the code to set the RGMII delays
into a shared helper.

Subject: net: phy: marvell: Use the set_polarity helper

Some of the init functions unilaterally enable set auto cross over
without using the helper. Make use of the helper, and respect the
phydev MDI configuration.

Clean up the #define used while setting polarity, and the other
functions of the bits in the register.

Subject: clk: sunxi-ng: Fix fractional mode for N-M clocks

N-M factor clock driver is missing a call to ccu_frac_helper_enable()
when fractional mode is used. Additionally, most SoCs require that M
factor must be set to 0 when fractional mode is used.

Without this patch, clock keeps the old value and clk_set_rate() returns
without error.

Subject: iwlwifi: mvm: fix TCP CSUM offload with WEP and A000 series

When we enabled TCP checksum offload, we need to tell the
firmware where the IP header starts. If we have an IV, then
we need to adapt that value since the IV is placed before
the SNAP header. This is true only for cases where the
driver adds the IV, not the WEP case in which the IV is
added by the firmware itself.

On A000 devices series, the IV is always added by the
device.

Fix this.

it.
Add the TLV bit to avoid getting the print:

a control channel with HT40+ since  (40, 44) is invalid.

Because of that, cfg80211 would allow to connect in 40MHz
to APs that are configured to channel 40 HT40+ and that made
our firmware assert.

Fix this by checking the bandwidth flags before taking the
decision if the rule should be split.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.

Subject: iwlwifi: mvm: set A-MPDU bit upon empty BA notification from FW

The bit was set only if there was at least one reclaimed frame in an
aggregation. It's important to set it also in the case that the whole
A-MPDU was lost, otherwise rate scaling statistics will not be
updated correctly. Thus, set it always in ba notification handler.

This fixes a throughput degradation of about 20% in certain scenarios
with multiple streams on 11ac.

Subject: iwlwifi: mvm: rs: fix TLC statistics collection

Statistics should be collected according to the actual rate a
frame/aggregation was transmitted and not according to the initial rate
from the last LQ command (these rates are different if the frames were
retransmitted at a lower rate from the rate scale table).

This is needed to remove throughput degradation.

for_each_obj_in_state is about to be removed, so use the correct new

I renamed the variable to 'unused', but forgot to convert
drm_atomic_helper_wait_for_flip_done to the new iterator macro,
so make it work this time.

Subject: drm/nouveau: Convert nouveau to use new iterator macros, v2.

Use the new atomic iterator macros, the old ones are about to be
removed. With the new macros, it's more easy to get old and new state so
get them from the macros instead of from obj->state.

Changes since v1:
- Don't mix up old and new state. (danvet)
- Rebase on top of interruptible swap_state changes.

Subject: drm/msm: Convert to use new iterator macros, v2.

for_each_obj_in_state is about to be removed, so convert
to the new iterator macros.

Just like in omap, use crtc_state->active instead of
crtc_state->enable when waiting for completion.

Changes since v1:
- Fix compilation.

Subject: iwlwifi: mvm: set the RTS_MIMO_PROT bit in flag mask when sending sta
 to fw

Set the STA_FLG_RTS_MIMO_PROT bit in station_flags_msk of the add sta
command, so that when smps mode changes, the FW will know about it.

In particular, in AP mode, clients are added upon receival of an auth
request, at which point there's no knowledge of the client's smps mode.
When the assoc request arrives, the add_sta command is resent to modify
the station parameters. At this point the driver knows the smps mode,
but since the corresponding bit in the mask is not set, the fw doesn't
update this field so there's no rts protection for mimo.

Subject: iwlwifi: track current firmware image in common code

Track the current firmware image in the common code instead
of in the opmode so that later patches can access it there
in a common way.

From d172a5eff629127c048272e5d44e8b9f9cd30eac Mon Sep 17 00:00:00 2001

Subject: iwlwifi: reorganize firmware API

Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new
fw/api/ directory.

While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.

Subject: iwlwifi: mvm: check family instead of new TX API for workarounds

There are two workarounds because RSS is currently broken on A000
devices due to firmware issues, but checking for the new TX API
doesn't really make sense. Check the hardware family instead of
the new TX API - there's nothing better to check since it's just
a temporary workaround.

Subject: iwlwifi: mvm: byte-swap constant instead of variable

Convention has it to byte-swap the constant instead of the variable
when doing bit checks. This also generates better code when the swap
is actually needed, since the constant can be swapped at compile-time.

Subject: iwlwifi: mvm: refactor beacon template command code

We currently support 3 different versions of the beacon template
command and the code does some tricks in order to reuse what is
possible across these versions.  But it is a bit complicated to read
and soon there will be one more variation that the driver needs
implement, which would complicate it even further.

Refactor the way we send beacon template commands, which increases the
code size a bit, but makes it much easier to read.

The FIFO numbering is different in A000 devices. This
means that we routed BE packets to BK FIFO. Fix this.

Subject: iwlwifi: implement fseq version mismatch warning

During init, the FW checks whether the FSEQ value matches what it
expects.  If it doesn't match, we print a warning to let integrators
clearly know that something is wrong.  This can happen if another core
(i.e. not WiFi) has updated the FSEQ version.  This notification is
only sent by the FW in production, for development firmwares, an
assertion is triggered instead.

Subject: iwlwifi: pcie: rename iwl_trans_check_hw_rf_kill() to pcie

Rename this function to the more appropriate iwl_pcie_check_hw_rf_kill()
since it's only a function in the pcie code and cannot be called from
any other place.

Subject: iwlwifi: mvm: require AP_LINK_PS for TVQM

Since the TXQ timer freeze code will not properly handle the
large TVQM queue numbers, warn if we get into that code when
we have TVQM. Also, just to catch this earlier, warn if the
firmware image doesn't support AP_LINK_PS but we're running
on HW using TVQM.

Subject: HID: Remove the semaphore driver_lock

The semaphore 'driver_lock' is used as a simple mutex, and also unnecessary as
suggested by Arnd. Hence removing it, as the concurrency between the probe and
remove is already handled in the driver core.

Subject: PCI / PM: Skip bridges in pci_enable_wake()

PCI bridges only have a reason to generate wakeup signals on behalf
of devices below them, so avoid preparing bridges for wakeup directly
in pci_enable_wake().

Also drop the pci_has_subordinate() check from pci_pm_default_resume()
as this will be done by pci_enable_wake() itself now.

Subject: ACPI / PM: Split acpi_device_wakeup()

To prepare for a subsequent change and make the code somewhat easier
to follow, do the following in the ACPI device wakeup handling code:

 * Replace wakeup.flags.enabled under struct acpi_device with
   wakeup.enable_count as that will be necessary going forward.

   For now, wakeup.enable_count is not allowed to grow beyond 1,
   so the current behavior is retained.

 * Split acpi_device_wakeup() into acpi_device_wakeup_enable()
   and acpi_device_wakeup_disable() and modify the callers of
   it accordingly.

 * Introduce a new acpi_wakeup_lock mutex to protect the wakeup
   enabling/disabling code from races in case it is executed
   more than once in parallel for the same device (which may
   happen for bridges theoretically).

Subject: ACPI / PCI / PM: Rework acpi_pci_propagate_wakeup()

The acpi_pci_propagate_wakeup() routine is there to handle cases in
which PCI bridges (or PCIe ports) are expected to signal wakeup
for devices below them, but currently it doesn't do that correctly.

The problem is that acpi_pci_propagate_wakeup() uses
acpi_pm_set_device_wakeup() for bridges and if that routine is
called for multiple times to disable wakeup for the same device,
it will disable it on the first invocation and the next calls
will have no effect (it works analogously when called to enable
wakeup, but that is not a problem).

Now, say acpi_pci_propagate_wakeup() has been called for two
different devices under the same bridge and it has called
acpi_pm_set_device_wakeup() for that bridge each time.  The
bridge is now enabled to generate wakeup signals.  Next,
suppose that one of the devices below it resumes and
acpi_pci_propagate_wakeup() is called to disable wakeup for that
device.  It will then call acpi_pm_set_device_wakeup() for the bridge
and that will effectively disable remote wakeup for all devices under
it even though some of them may still be suspended and remote wakeup
may be expected to work for them.

To address this (arguably theoretical) issue, allow
wakeup.enable_count under struct acpi_device to grow beyond 1 in
certain situations.  In particular, allow that to happen in
acpi_pci_propagate_wakeup() when wakeup is enabled or disabled
for PCI bridges, so that wakeup is actually disabled for the
bridge when all devices under it resume and not when just one
of them does that.

Subject: PM / OPP: Fix get sharing CPUs when hotplug is used

We fail dev_pm_opp_of_get_sharing_cpus() when possible CPU device does
not exist. This can happen on platforms where not all possible CPUs
are available at start up ie. hotplugged out.  The CPU device is not
registered in the system so we are not able to check struct device to
set the sharing CPUs bitmask properly.

Example (real use case):
2 physical MIPS cores, 4 VPE, cpu0/2 run Linux and cpu1/3 are not
available for Linux at boot up. cpufreq-dt driver + OPP v2 fail to
register opp_table due to the fact there is no struct device for
cpu1 (remains offline at
bootup).

To solve the bug, stop using device struct to check device_node.
Instead get CPU device_node directly from device tree with
of_get_cpu_node().

Subject: sched: cpufreq: Allow remote cpufreq callbacks

With Android UI and benchmarks the latency of cpufreq response to
certain scheduling events can become very critical. Currently, callbacks
into cpufreq governors are only made from the scheduler if the target
CPU of the event is the same as the current CPU. This means there are
certain situations where a target CPU may not run the cpufreq governor
for some time.

One testcase to show this behavior is where a task starts running on
CPU0, then a new task is also spawned on CPU0 by a task on CPU1. If the
system is configured such that the new tasks should receive maximum
demand initially, this should result in CPU0 increasing frequency
immediately. But because of the above mentioned limitation though, this
does not occur.

This patch updates the scheduler core to call the cpufreq callbacks for
remote CPUs as well.

The schedutil, ondemand and conservative governors are updated to
process cpufreq utilization update hooks called for remote CPUs where
the remote CPU is managed by the cpufreq policy of the local CPU.

The intel_pstate driver is updated to always reject remote callbacks.

This is tested with couple of usecases (Android: hackbench, recentfling,
galleryfling, vellamo, Ubuntu: hackbench) on ARM hikey board (64 bit
octa-core, single policy). Only galleryfling showed minor improvements,
while others didn't had much deviation.

The reason being that this patch only targets a corner case, where
following are required to be true to improve performance and that
doesn't happen too often with these tests:

- Task is migrated to another CPU.
- The task has high demand, and should take the target CPU to higher
  OPPs.
- And the target CPU doesn't call into the cpufreq governor until the
  next tick.

Based on initial work from Steve Muckle.

Subject: cpufreq: Process remote callbacks from any CPU if the platform
 permits

On many platforms, CPUs can do DVFS across cpufreq policies. i.e CPU
from policy-A can change frequency of CPUs belonging to policy-B.

This is quite common in case of ARM platforms where we don't
configure any per-cpu register.

Add a flag to identify such platforms and update
cpufreq_can_do_remote_dvfs() to allow remote callbacks if this flag is
set.

Also enable the flag for cpufreq-dt driver which is used only on ARM
platforms currently.

Subject: fs: convert a pile of fsync routines to errseq_t based reporting

This patch converts most of the in-kernel filesystems that do writeback
out of the pagecache to report errors using the errseq_t-based
infrastructure that was recently added. This allows them to report
errors once for each open file description.

Most filesystems have a fairly straightforward fsync operation. They
call filemap_write_and_wait_range to write back all of the data and
wait on it, and then (sometimes) sync out the metadata.

For those filesystems this is a straightforward conversion from calling
filemap_write_and_wait_range in their fsync operation to calling
file_write_and_wait_range.

Subject: omapfb: panel-tpo-td043mtea1: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

File size before:

Subject: video: fbdev: vt8623fb: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  11790	   1913	      0	  13703	   3587	drivers/video/fbdev/vt8623fb.o

File size after adding 'const':
   text	   data	    bss	    dec	    hex	filename
  11854	   1849	      0	  13703	   3587	drivers/video/fbdev/vt8623fb.o

Subject: fbcon: Make fbcon a built-time depency for fbdev

There's a bunch of folks who're trying to make printk less
contended and faster, but there's a problem: printk uses the
console_lock, and the console lock has become the BKL for all things
fbdev/fbcon, which in turn pulled in half the drm subsystem under that
lock. That's awkward.

There reasons for that is probably just a historical accident:

- fbcon is a runtime option of fbdev, i.e. at runtime you can pick
  whether your fbdev driver instances are used as kernel consoles.
  Unfortunately this wasn't implemented with some module option, but
  through some module loading magic: As long as you don't load
  fbcon.ko, there's no fbdev console support, but loading it (in any
  order wrt fbdev drivers) will create console instances for all fbdev
  drivers.

- This was implemented through a notifier chain. fbcon.ko enumerates
  all fbdev instances at load time and also registers itself as
  listener in the fbdev notifier. The fbdev core tries to register new
  fbdev instances with fbcon using the notifier.

- On top of that the modifier chain is also used at runtime by the
  fbdev subsystem to e.g. control backlights for panels.

- The problem is that the notifier puts a mutex locking context
  between fbdev and fbcon, which mixes up the locking contexts for
  both the runtime usage and the register time usage to notify fbcon.
  And at runtime fbcon (through the fbdev core) might call into the
  notifier from a printk critical section while console_lock is held.

- This means console_lock must be an outer lock for the entire fbdev
  subsystem, which also means it must be acquired when registering a
  new framebuffer driver as the outermost lock since we might call
  into fbcon (through the notifier) which would result in a locking
  inversion if fbcon would acquire the console_lock from its notifier
  callback (which it needs to register the console).

- console_lock can be held anywhere, since printk can be called
  anywhere, and through the above story, plus drm/kms being an fbdev
  driver, we pull in a shocking amount of locking hiercharchy
  underneath the console_lock. Which makes cleaning up printk really
  hard (not even splitting console_lock into an rwsem is all that
  useful due to this).

There's various ways to address this, but the cleanest would be to
make fbcon a compile-time option, where fbdev directly calls the fbcon
register functions from register_framebuffer, or dummy static inline
versions if fbcon is disabled. Maybe augmented with a runtime knob to
disable fbcon, if that's needed (for debugging perhaps).

But this could break some users who rely on the magic "loading
fbcon.ko enables/disables fbdev framebuffers at runtime" thing, even
if that's unlikely. Hence we must be careful:

1. Create a compile-time dependency between fbcon and fbdev in the
least minimal way. This is what this patch does.

2. Wait at least 1 year to give possible users time to scream about
how we broke their setup. Unlikely, since all distros make fbcon
compile-in, and embedded platforms only compile stuff they know they
need anyway. But still.

3. Convert the notifier to direct functions calls, with dummy static
inlines if fbcon is disabled. We'll still need the fb notifier for the
other uses (like backlights), but we can probably move it into the fb
core (atm it must be built-into vmlinux).

4. Push console_lock down the call-chain, until it is down in
console_register again.

5. Finally start to clean up and rework the printk/console locking.

For context of this saga see

    fb: rework locking to fix lock ordering on takeover

plus the pile of commits on top that tried to make this all work
without terminally upsetting lockdep. We've uncovered all this when
console_lock lockdep annotations where added in

commit daee779718a319ff9f83e1ba3339334ac650bb22
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Sat Sep 22 19:52:11 2012 +0200

    console: implement lockdep support for console_lock

On the patch itself:
- Switch CONFIG_FRAMEBUFFER_CONSOLE to be a boolean, using the overall
  CONFIG_FB tristate to decided whether it should be a module or
  built-in.

- At first I thought I could force the build depency with just a dummy
  symbol that fbcon.ko exports and fb.ko uses. But that leads to a
  module depency cycle (it works fine when built-in).

  Since this tight binding is the entire goal the simplest solution is
  to move all the fbcon modules (and there's a bunch of optinal
  source-files which are each modules of their own, for no good
  reason) into the overall fb.ko core module. That's a bit more than
  what I would have liked to do in this patch, but oh well.

- * (SCROLL_WRAP_REDRAW is not implemented yet)
- *
- * In general, fbcon will choose the best scrolling
- * method based on the rule below:
- *
- * Pan/Wrap > accel imageblit > accel copyarea >
- * soft imageblit > (soft copyarea)
- *
- * Exception to the rule: Pan + accel copyarea is
- * preferred over Pan + accel imageblit.
- *
- * The above is typical for PCI/AGP cards. Unless
- * overridden, fbcon will never use soft copyarea.
- *
- * If you need to override the above rule, set the
- * appropriate flags in fb_info->flags.  For example,
- * to prefer copyarea over imageblit, set
- * FBINFO_READS_FAST.
- *
- * Other notes:
- * + use the hardware engine to move the text
- *    (hw-accelerated copyarea() and fillrect())
- * + use hardware-supported panning on a large virtual screen
- * + amifb can not only pan, but also wrap the display by N lines
- *    (i.e. visible line i = physical line (i+N) % yres).
- * + read what's already rendered on the screen and
- *     write it in a different place (this is cfb_copyarea())
- * + re-render the text to the screen
- *
- * Whether to use wrapping or panning can only be figured out at
- * runtime (when we know whether our font height is a multiple
- * of the pan/wrap step)
- *

+ *---------------------------------------------
+ * SCROLL_MOVE         copyarea    No     No
+ * SCROLL_PAN_MOVE     copyarea    Yes    No
+ * SCROLL_WRAP_MOVE    copyarea    No     Yes

+ * SCROLL_PAN_REDRAW   imageblit   Yes    No
+ * SCROLL_WRAP_REDRAW  imageblit   No     Yes
+ *
+ * (SCROLL_WRAP_REDRAW is not implemented yet)
+ *
+ * In general, fbcon will choose the best scrolling
+ * method based on the rule below:
+ *
+ * Pan/Wrap > accel imageblit > accel copyarea >
+ * soft imageblit > (soft copyarea)
+ *
+ * Exception to the rule: Pan + accel copyarea is
+ * preferred over Pan + accel imageblit.
+ *
+ * The above is typical for PCI/AGP cards. Unless
+ * overridden, fbcon will never use soft copyarea.
+ *
+ * If you need to override the above rule, set the
+ * appropriate flags in fb_info->flags.  For example,
+ * to prefer copyarea over imageblit, set
+ * FBINFO_READS_FAST.
+ *
+ * Other notes:
+ * + use the hardware engine to move the text
+ *    (hw-accelerated copyarea() and fillrect())
+ * + use hardware-supported panning on a large virtual screen
+ * + amifb can not only pan, but also wrap the display by N lines
+ *    (i.e. visible line i = physical line (i+N) % yres).
+ * + read what's already rendered on the screen and
+ *     write it in a different place (this is cfb_copyarea())
+ * + re-render the text to the screen
+ *
+ * Whether to use wrapping or panning can only be figured out at
+ * runtime (when we know whether our font height is a multiple
+ * of the pan/wrap step)

Subject: fbdev: Nuke FBINFO_MODULE

Instead check info->ops->owner, which amounts to the same.

Spotted because I want to remove the pile of broken and cargo-culted
fb_info->flags assignments in drm drivers.

Subject: drm: Plumb modifiers through plane init

This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

From: Ben Widawsky <ben@bwidawsk.net>
Date: Sun, 23 Jul 2017 20:46:39 -0700
Subject: drm: Create a format/modifier blob

Updated blob layout (Rob, Daniel, Kristian, xerpi)

v2:
* Removed __packed, and alignment (.+)
* Fix indent in drm_format_modifier fields (Liviu)
* Remove duplicated modifier > 64 check (Liviu)
* Change comment about modifier (Liviu)
* Remove arguments to blob creation, use plane instead (Liviu)
* Fix data types (Ben)
* Make the blob part of uapi (Daniel)

v3:
Remove unused ret field.
Change i, and j to unsigned int (Emil)

v4:
Use plane->modifier_count instead of recounting (Daniel)

v5:
Rename modifiers to modifiers_property (Ville)
Use sizeof(__u32) instead to reflect UAPI nature (Ville)
Make BUILD_BUG_ON for blob header size

Subject: Revert "serial: Delete dead code for CIR serial ports"

This reverts commit 1104321a7b3bb670dc614ffa7958c553e7b3b836.

The code is not dead at all and breaks winbond-cir.

Serial: 8250/16550 driver, 32 ports, IRQ sharing enabled
00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
00:03: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a CIR port
lirc lirc0: lirc_dev: driver ir-lirc-codec (winbond-cir) registered at minor = 0
winbond-cir 00:03: Region 0x2f8-0x2ff already in use!

Subject: of/device: use of_property_for_each_string to parse compatible

Instead of directly parsing the compatible property, use the
of_property_for_each_string() helper to iterate over each compatible
string. This reduces the LoC and makes the functions easier to
understand.

Convert the interrupts property parsing to use the OF property API
instead of open coding the parsing of the raw property value. This saves
a number of LoC, and the result is easier to read.

Subject: ntb: transport shouldn't disable link due to bogus values in SPADs

It seems that under certain scenarios the SPAD can have bogus values caused
by an agent (i.e. BIOS or other software) that is not the kernel driver, and
that causes memory window setup failure. This should not cause the link to
be disabled because if we do that, the driver will never recover again. We
have verified in testing that this issue happens and prevents proper link
recovery.

Subject: mtd: spi-nor: Recover from Spansion/Cypress errors

S25FL{128|256|512}S datasheets say:
"When P_ERR or E_ERR bits are set to one, the WIP bit will remain set to
one indicating the device remains busy and unable to receive new operation
commands. A Clear Status Register (CLSR) command must be received to return
the device to standby mode."

Current spi-nor code works until first error occurs, but write/erase errors
are not just rare hardware failures, they also occur if user tries to flash
write-protected areas. After such attempt no SPI command can be executed
any more and even read fails. This patch adds support for P_ERR and E_ERR
bits in Status Register 1 (so that operation fails immediately and not
after a long timeout) and proper recovery from the error condition.

Tested on Spansion S25FS128S, which is supported by S25FL129P entry.

This happens because in the first case we were initializing a two

struct containing two arrays with {0}.

Fix them by adding another pair of {}.

Subject: drm/msm: fix an integer overflow test

We recently added an integer overflow check but it needs an additional
tweak to work properly on 32 bit systems.

The problem is that we're doing the right hand side of the assignment as
type unsigned long so the max it will have an integer overflow instead
of being larger than SIZE_MAX.  That means the "sz > SIZE_MAX" condition
is never true even on 32 bit systems.  We need to first cast it to u64
and then do the math.

Subject: drm/msm/dsi: Calculate link clock rates with updated dsi->lanes

After the commit mentioned below, we start computing the byte and pixel
clocks (dsi_calc_clk_rate) in the DSI bridge's mode_set() op. The
calculation involves the number of DSI lanes being used by the
downstream bridge/panel.

If the downstream bridge/panel tries to change the number of DSI lanes
(as done in the ADV7533 driver) in its mode_set() op, then our DSI
host driver will not have the correct number of lanes when computing
byte/pixel clocks.

Fix this by delaying the clock rate calculation in the DSI bridge
enable path. In particular, compute the clock rates in
msm_dsi_host_get_phy_clk_req().

This fixes the DSI host error interrupts seen when we try to switch
between modes that require different number of lanes (4 to 3 lanes, or
vice versa) on db410c. The error interrupts occur since the byte/pixel
clock rates aren't according to what the DSI video mode timing engine
expects.

Subject: platform/x86: dell-wmi: Fix driver interface version query
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When I converted dell-wmi to the new bus infrastructure, I left the
call to dell_wmi_check_descriptor_buffer() in dell_wmi_init().  This
could cause two problems:

 - An error message when loading the driver on a system without
   dell-wmi.  We'd try to read the event descriptor even if the WMI
   GUID wasn't there.

 - A possible race if dell-wmi was loaded manually before wmi was
   fully initialized.

Fix it by moving the call to the probe function where it belongs.

Subject: platform/x86: intel-hid: Wake up Dell Latitude 7275 from
 suspend-to-idle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Dell Latitude 7275 the 5-button array is not exposed in the
ACPI tables, but still notifies are sent to the Intel HID device
object (device ID INT33D5) in response to power button actions while
suspended to idle.  However, they are currently ignored as the
intel-hid driver is not prepared to take care of them.

As a result, power button wakeup from suspend-to-idle doesn't work
on this platform, but suspend-to-idle is the only reliable suspend
variant on it (the S3 implementation in the platform firmware turns
out to be broken), so it would be good to handle it properly.

For this reason, add an upfront check against the power button press
event (0xCE) to notify_handler() in the wakeup mode which allows it
to catch the power button wakeup notification on the affected
platform (even though priv->array is NULL on it) and should not
change the behavior on platforms with priv->array present (because
priv->array contains the event in question in those cases).

Subject: ptp: introduce ptp auxiliary worker

Many PTP drivers required to perform some asynchronous or periodic work,
like periodically handling PHC counter overflow or handle delayed timestamp
for RX/TX network packets. In most of the cases, such work is implemented
using workqueues. Unfortunately, Kernel workqueues might introduce
significant delay in work scheduling under high system load and on -RT,
which could cause misbehavior of PTP drivers due to internal counter
overflow, for example, and there is no way to tune its execution policy and
priority manuallly.

Hence, The kthread_worker can be used insted of workqueues, as it create
separte named kthread for each worker and its its execution policy and
priority can be configured using chrt tool.

This prblem was reported for two drivers TI CPSW CPTS and dp83640, so
instead of modifying each of these driver it was proposed to add PTP
auxiliary worker to the PHC subsystem.

The patch adds PTP auxiliary worker in PHC subsystem using kthread_worker
and kthread_delayed_work and introduces two new PHC subsystem APIs:

- long (*do_aux_work)(struct ptp_clock_info *ptp) callback in
ptp_clock_info structure, which driver should assign if it require to
perform asynchronous or periodic work. Driver should return the delay of
the PTP next auxiliary work scheduling time (>=0) or negative value in case
further scheduling is not required.

- int ptp_schedule_worker(struct ptp_clock *ptp, unsigned long delay) which
allows schedule PTP auxiliary work.

The name of kthread_worker thread corresponds PTP PHC device name "ptp%d".

Subject: net: ethernet: ti: cpts: convert to use ptp auxiliary worker

There could be significant delay in CPTS work schedule under high system
load and on -RT which could cause CPTS misbehavior due to internal counter
overflow. Usage of own kthread_worker allows to avoid such kind of issues
and makes it possible to tune priority of CPTS kthread_worker thread on -RT
(thread name "cpts").

Hence, the CPTS driver is converted to use PTP auxiliary worker as PHC
subsystem implements such functionality in a generic way now.

Subject: net: ethernet: ti: cpts: fix tx timestamping timeout

With the low speed Ethernet connection CPDMA notification about packet
processing can be received before CPTS TX timestamp event, which is set
when packet actually left CPSW while cpdma notification is sent when packet
pushed in CPSW fifo.  As result, when connection is slow and CPU is fast
enough TX timestamping is not working properly.

Fix it, by introducing TX SKB queue to store PTP SKBs for which Ethernet
Transmit Event hasn't been received yet and then re-check this queue
with new Ethernet Transmit Events by scheduling CPTS overflow
work more often (every 1 jiffies) until TX SKB queue is not empty.

Side effect of this change is:
 - User space tools require to take into account possible delay in TX
timestamp processing (for example ptp4l works with tx_timestamp_timeout=400
under net traffic and tx_timestamp_timeout=25 in idle).

Subject: net: ethernet: ti: cpts: fix fifo read in cpts_find_ts

Now the call chain
 cpts_find_ts()
  |- cpts_fifo_read(cpts, CPTS_EV_PUSH)

will stop reading CPTS FIFO if PUSH event is found. But this is not
expected and CPTS FIFI should be completely drained here. This is most
probably copy-paste error and it has no negative impact as CPTS_EV_PUSH
should not be present in FIFO without TS_PUSH request and
cpts_systim_read() and cpts_find_ts() synchronized by spin_lock.

Correct above by calling cpts_fifo_read() with -1 parameter, so it will
read all CPTS event from FIFO.

The mdp5_cmd_encoder_disable is accidentally called in the encoder enable
path. We've not seen any problems since we haven't tested with command
mode panels in a while. Fix the copy-paste error.

Subject: drm/msm/mdp5: Drop clock names with "_clk" suffix

We have upstream bindings (msm8916) that have the "_clk" suffix in the
clock names. The downstream bindings also require it.

We want to drop the "_clk" suffix and at the same time support existing
bindings. Update the MDP5 code with the the msm_clk_get() helper to
support both old and new clock names.

Subject: net-next: mediatek: add platform data to adapt into various hardware

This patch is the preparation patch in order to adapt into various
hardware through adding platform data which holds specific characteristics
among MediaTek SoCs and introducing the unified clock handler for those
distinct clock requirements depending on different features such as
TRGMII and SGMII getting support on the target SoC. And finally, add
enhancement with given the generic description for Kconfig and remove the
unnecessary machine type dependency in Makefile.

Subject: net-next: mediatek: add support for MediaTek MT7622 SoC

This patch adds the driver for ethernet controller on MT7622 SoC. It has
the similar handling logic as the previously MT7623 does, but there are
additions against with MT7623 SoC, the shared SGMII given for the dual
GMACs and including 5-ports 10/100 embedded switch support (ESW) as the
GMAC1 option, thus more clocks consumers for the extra feature are
introduced here. So for ease portability and maintenance, those
differences all are being kept inside the platform data as other drivers
usually do. Currently testing successfully is done with those patches for
the conditions such as GMAC2 with IP1001 PHY via RGMII and GMAC1/2 with
RTL8211F PHY via SGMII.

Subject: vxlan: fix remcsum when GRO on and CHECKSUM_PARTIAL boundary is outer
 UDP

In the case that GRO is turned on and the original received packet is
CHECKSUM_PARTIAL, if the outer UDP header is exactly at the last
csum-unnecessary point, which for instance could occur if the packet
comes from another Linux guest on the same Linux host, we have to do
either remcsum_adjust or set up CHECKSUM_PARTIAL again with its
csum_start properly reset considering RCO.

However, since b7fe10e5ebac("gro: Fix remcsum offload to deal with frags
in GRO") that barrier in such case could be skipped if GRO turned on,
hence we pass over it and the inner L4 validation mistakenly reckons
it as a bad csum.

This patch makes remcsum_offload being reset at the same time of GRO
remcsum cleanup, so as to make it work in such case as before.

Fixes: b7fe10e5ebac ("gro: Fix remcsum offload to deal with frags in GRO")

Subject: drm/msm: Remove some potentially blocked register ranges

The 0xf400 and 0xf800 ranges are in the RBBM_SECVID block which may
be protected from CPU access. Skip dumping them since they are minimally
useful for debugging and they aren't worth a system hang.

Subject: drm/msm: Allow hardware clock gating to be toggled

There are some use cases wherein we need to turn off hardware clock
gating before reading certain registers. Modify the A5XX HWCG function
to allow user to enable or disable clock gating at will.

On A5XX GPU hardware clock gating needs to be turned off before

Subject: drm/msm: gpu: call qcom_mdt interfaces only for ARCH_QCOM

When compile-testing for something other than ARCH_QCOM,
we run into a link error:

drivers/gpu/drm/msm/adreno/a5xx_gpu.o: In function `a5xx_hw_init':
a5xx_gpu.c:(.text.a5xx_hw_init+0x600): undefined reference to `qcom_mdt_get_size'
a5xx_gpu.c:(.text.a5xx_hw_init+0x93c): undefined reference to `qcom_mdt_load'

There is already an #ifdef that tries to check for CONFIG_QCOM_MDT_LOADER,
but that symbol is only meaningful when building for ARCH_QCOM.

This adds a compile-time check for ARCH_QCOM, and clarifies the
Kconfig select statement so we don't even try it for other targets.

The check for CONFIG_QCOM_MDT_LOADER can then go away, which also
improves compile-time coverage and makes the code a little nicer
to read.

Subject: drm/msm: gpu: don't abuse dma_alloc for non-DMA allocations

In zap_shader_load_mdt(), we pass a pointer to a phys_addr_t
into dmam_alloc_coherent, which the compiler warns about:

drivers/gpu/drm/msm/adreno/a5xx_gpu.c: In function 'zap_shader_load_mdt':
drivers/gpu/drm/msm/adreno/a5xx_gpu.c:54:50: error: passing argument 3 of 'dmam_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]

The returned DMA address is later passed on to a function that
takes a phys_addr_t, so it's clearly wrong to use the DMA
mapping interface here: the memory may be uncached, or the
address may be completely wrong if there is an IOMMU connected
to the device. What the code actually wants to do is to get
the physical address from the reserved-mem node. It goes through
the dma-mapping interfaces for obscure reasons, and this
apparently only works by chance, relying on specific bugs
in the error handling of the arm64 dma-mapping implementation.

The same problem existed in the "venus" media driver, which was
now fixed by Stanimir Varbanov after long discussions.

In order to make some progress here, I have now ported his
approach over to the adreno driver. The patch is currently
untested, and should get a good review, but it is now much
simpler than the original, and it should be obvious what
goes wrong if I made a mistake in the port.

Subject: ravb: add wake-on-lan support via magic packet
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

WoL is enabled in the suspend callback by setting MagicPacket detection
and disabling all interrupts expect MagicPacket. In the resume path the
driver needs to reset the hardware to rearm the WoL logic, this prevents
the driver from simply restoring the registers and to take advantage of
that ravb was not suspended to reduce resume time. To reset the
hardware the driver closes the device, sets it in reset mode and reopens
the device just like it would do in a normal suspend/resume scenario
without WoL enabled, but it both closes and opens the device in the
resume callback since the device needs to be reset for WoL to work.

One quirk needed for WoL is that the module clock needs to be prevented
from being switched off by Runtime PM. To keep the clock alive the
suspend callback need to call clk_enable() directly to increase the
usage count of the clock. Then when Runtime PM decreases the clock usage
count it won't reach 0 and be switched off.

Subject: ravb: add workaround for clock when resuming with WoL enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The renesas-cpg-mssr clock driver are not yet aware of PSCI sleep where
power is cut to the SoC. When resuming from this state with WoL enabled
the enable count of the ravb clock is 1 and the clock driver thinks the
clock is already on when PM core enables the clock and increments the
enable count to 2. This will result in the ravb driver failing to talk
to the hardware since the module clock is off. Work around this by
forcing the enable count to 0 and then back to 2 when resuming with WoL
enabled.

This workaround should be reverted once the renesas-cpg-mssr clock
driver becomes aware of this PSCI sleep behavior.

Subject: PCI: Add pci_reset_function_locked()

The implementation of PCI workarounds may require that the device is reset
from its probe function.  This implies that the PCI device lock is already
held, and makes calling pci_reset_function() impossible (since it will
itself try to take that lock).

Add pci_reset_function_locked(), which is the equivalent of
pci_reset_function(), except that it requires the PCI device lock to be
already held by the caller.

Subject: drm/i915/gvt: clean workload queue if error happened

If a workload caused a HW GPU hang or it is in the middle of
vGPU reset, the workload queue should be cleaned up to emulate
the hang state of the GPU.

v2:
- use ENGINE_MASK(ring_id) instead of (1 << ring_id). (Zhenyu)

Subject: drm/ast: Actually load DP501 firmware when required

The ast driver has a code to load the DP501 firmware, but it's never
used.  This patch implements its actual usage by requesting the
firmware on demand, and release the firmware at exit as well.

Also the path contains a few cleanups and makes relevant functions
static.

Subject: net: dsa: qca8k: fix EEE init

The qca8k obviously copied code from the sf2 driver as how to set EEE:

    if (e->eee_enabled) {
        p->eee_enabled = qca8k_eee_init(ds, port, phydev);
        if (!p->eee_enabled)
            ret = -EOPNOTSUPP;
    }

But it did not use the same logic for the EEE init routine, which is
"Returns 0 if EEE was not enabled, or 1 otherwise". This results in
returning -EOPNOTSUPP on success and caching EEE enabled on failure.

This patch fixes the returned value of qca8k_eee_init.

Subject: net: dsa: qca8k: do not cache unneeded EEE fields

The qca8k driver is currently caching a bitfield of the supported member
of a ethtool_eee private structure, which is unused.

Only the eee_enabled field of the private ethtool_eee copy is updated,
thus using p->advertised and p->lp_advertised is also erroneous.

Remove the usage of these private ethtool_eee members and only rely on
phy_ethtool_get_eee to assign the eee_active member.

Subject: net: dsa: mv88e6xxx: call phy_init_eee

It is safer to init the EEE before the DSA layer call
phy_ethtool_set_eee, as sf2 and qca8k are doing.

Subject: net: dsa: call phy_init_eee in DSA layer

All DSA drivers are calling phy_init_eee if eee_enabled is true.

Move up this statement in the DSA layer to simplify the DSA drivers.
qca8k does not require to cache the ethtool_eee structures from now on.

Subject: net: dsa: remove PHY device argument from .set_eee

The DSA switch operations for EEE are only meant to configure a port's
MAC EEE settings. The port's PHY EEE settings are accessed by the DSA
layer and must be made available via a proper PHY driver.

In order to reduce this confusion, remove the phy_device argument from
the .set_eee operation.

Subject: net: dsa: mv88e6xxx: remove EEE support

The PHY's EEE settings are already accessed by the DSA layer through the
Marvell PHY driver and there is nothing to be done for switch's MACs.

Remove all EEE support from the mv88e6xxx driver and simply return 0
from the EEE ops.

Subject: EDAC, sb_edac: Classify memory mirroring modes

Basically, there are full memory mirroring and address range partial
memory mirroring (supported by Haswell EX and Broadwell EX) modes.

a) In full memory mirroring, the memory behind each memory controller
   is mirrored, i.e. the memory is split into two identical mirrors
   (primary and secondary), half of the memory is reserved for redundancy.

b) In address range partial memory mirroring, the memory size (range)
   of primary and secondary behind each memory controller can be user
   defined by the TAD0 register. The rest of memory ranges defined by
   TAD1/TAD2/... in that memory controller are non-mirrored.

For more detail on memory mirroring, see the following link written by Tony Luck:

  https://01.org/lkp/blogs/tonyluck/2016/address-range-partial-memory-mirroring-linux

Currently the sb_edac driver only supports address decoding in full
memory mirroring and non-mirroring modes. In address range partial
memory mirroring mode, it may fail to decode an address that falls in a
non-mirroring area (the following was one of this kind of failed logs).

  Memory failure: 0x566d53a: Killing einj_mem_uc:4647 due to hardware memory corruption

  mce: [Hardware Error]: Machine check events logged

Therefore, classify memory mirroring modes and make the address decoding
in address range partial memory mode correct.

Subject: nand: fix wrong default oob layout for small pages using soft ecc

When using soft ecc, if no ooblayout is given, the core automatically
uses one of the nand_ooblayout_{sp,lp}*() functions to determine the
layout inside the out of band data.

Until kernel version 4.6, struct nand_ecclayout was used for that
purpose. During the migration from 4.6 to 4.7, an error shown up in the
small page layout, in the case oob section is only 8 bytes long.

The layout was using three bytes (0, 1, 2) for ecc, two bytes (3, 4)
as free bytes, one byte (5) for bad block marker and finally
two bytes (6, 7) as free bytes, as shown there:

[linux-4.6] drivers/mtd/nand/nand_base.c:52
static struct nand_ecclayout nand_oob_8 = {
	.eccbytes = 3,
	.eccpos = {0, 1, 2},
	.oobfree = {
		{.offset = 3,
		 .length = 2},
		{.offset = 6,
		 .length = 2} }
};

This fixes the current implementation which is incoherent. It
references bit 3 at the same time as an ecc byte and a free byte.

Furthermore, it is clear with the previous implementation that there
is only one ecc section with 8 bytes oob sections. We shall return
-ERANGE in the nand_ooblayout_ecc_sp() function when asked for the
second section.

Some ONFI NANDs do not support the SET/GET FEATURES commands, which,

On these NANDs we can't set a specific timing mode using the "timing
mode" feature, and we should assume the NAND does not require any setup

implement this now.

Batteries driven by the input reports will now start in "unknown" state,
and will get updated once we receive first report containing battery
strength from the device.

Subject: HID: input: optionally use device id in battery name

Manufacturers do not always populate serial number in their devices, so
let's fall back to device ID when forming the battery device name. As a
result, batteries in devices without serial number will be named like
this:

	hid-0018:2D1F:510E.0001-battery

(as opposed to hid--battery for the first one, and failing to create
batteries for the subsequent ones).

of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by <linux/of.h> work with const
of_device_ids. So mark the non-const structs as const.

Subject: drm/msm/mdp5: Use runtime PM get/put API instead of toggling clocks

mdp5_enable/disable calls are scattered all around in the MDP5 code.
Use the pm_runtime_get/put calls here instead, and populate the
runtime PM suspend/resume ops to manage the clocks.

About the overall design: MDP5 is a child of the top level MDSS
device. MDSS is also the parent to DSI, HDMI and other interfaces. When
we enable MDP5's power domain, we end up enabling MDSS's PD too. It is
only MDSS's PD that actually controlls the GDSC HW. Therefore, calling
runtime_get/put on the MDP5 device is like just requesting a vote to
enable/disable the GDSC.

Functionally, replacing the clock enable/disable calls with the RPM API
can result in the power domain (GDSC) state being toggled if no other
child isn't powered on. This can result in the register context being lost.
We make sure (in future commits) that code paths don't end up configuring
registers and then later lose state, resulting in a bad HW state.

For now, we've replaced each mdp5_enable/disable with runtime_get/put API.
We could optimize things later by removing runtime_get/put calls which
don't really need to be there. This could prevent unnecessary toggling of
the power domain and clocks.

Subject: drm/msm/hdmi: Set up runtime PM for HDMI

Enable rudimentary runtime PM in the HDMI driver. We can't really do
agressive PM toggling at the moment because we need to leave the hpd
clocks enabled all the time. There isn't much benefit of creating
suspend/resume ops to toggle clocks either.

We just make sure that we configure the power domain in the HDMI bridge's
enable/disable paths, and the HDMI connector's detect() op.

Subject: drm/msm/dsi: Set up runtime PM for DSI

Call the pm_runtime_get/put API where we need the clocks enabled.

The main entry/exit points are 1) enabling/disabling the DSI bridge
and 2) Sending commands from the DSI host to the device.

Subject: drm/msm/dsi: Implement RPM suspend/resume callbacks

The bus clocks are always enabled/disabled along with the power
domain, so move it to the runtime suspend/resume ops. This cleans
up the clock code a bit. Get rid of the clk_mutex mutex since it
isn't needed.

Subject: drm/msm/mdp5: Don't use mode_set helper funcs for encoders and CRTCs

We shouldn't use use mode_set/mode_set_nofb helpers when we use runtime
PM. The registers configured in these funcs lose their state when we
eventually enable the display pipeline.

Do not implement these vfuncs in the helpers, and call them in the
crtc_enable/encoder_enable paths instead.

Subject: drm/msm/mdp5: Write to SMP registers even if allocations don't change

Requests for assigning/freeing SMP blocks by planes are collected during
the atomic check phase, and represented by mdp5_smp_state's 'assigned'
and 'released' members.

Once the atomic state is committed, these members are reset to 0,
indicating that the existing configuration satisfies all the planes.
Future atomic commits will copy the old mdp5_smp_state, and the 'assigned'
and 'released' members would be updated only if there was a change in
the plane configurations.

When we disable and re-enable display, we lose the values we wrote to the
SMP registers, but the code doesn't program the registers because there
isn't any change in mdp5_smp_state.

Fix this by writing to the registers irrespective of whether there was
a change in SMP state or not. We do this by keeping a cache of the
register values, and write them every time we commit a state.

Subject: drm/msm/mdp5: Set up runtime PM for MDSS

MDSS represents the top level wrapper that contains MDP5, DSI, HDMI and
other sub-blocks. W.r.t device heirarchy, it's the parent of all these
devices. The power domain of this device is actually tied to the GDSC
hw. When any sub-device enables its PD, MDSS's PD is also enabled.

The suspend/resume ops enable the top level clocks that end at the MDSS
boundary. For now, we're letting them all be optional, since the child
devices anyway hold a ref to these clocks.

Until now, we'd called a runtime_get() during probe, which ensured that
the GDSC was always on. Now that we've set up runtime PM for the children
devices, we can get rid of this hack.

Note: that the MDSS device is the platform_device in msm_drv.c. The
msm_runtime_suspend/resume ops call the funcs that enable/disable
the top level MDSS clocks. This is different from MDP4, where the
platform device created in msm_drv.c represents MDP4 itself. It would
have been nicer to hide these differences by adding new kms funcs, but
runtime PM needs to be enabled before kms is set up (i.e, msm_kms_init
is called).

Subject: drm/msm: Remove uneeded platform dev members

Commit eeb754746b14 ("drm/msm/gpu: use pm-runtime") adds a pointer
for the GPU platform device to the msm_gpu struct so we can
happily remove the same pointers from the individual GPU
structs.

Subject: drm/msm: Add A5XX hardware fault detection

The A5XX GPU has really good hardware fault detection that can
detect a abnormal hardware condition and fire an interrupt in
a matter of milliseconds which is a lot better than waiting for
the hangcheck timer.

Enable the interrupt and log information before kicking off
recovery.

Subject: drm/i915: Fix out-of-bounds array access in bdw_load_gamma_lut

bdw_load_gamma_lut is writing beyond the array to the maximum value.
The intend of the function is to clamp values > 1 to 1, so write
the intended color to the max register.

This fixes the following KASAN warning:

Subject: tty: fix __tty_insert_flip_char regression

Sergey noticed a small but fatal mistake in __tty_insert_flip_char,
leading to an oops in an interrupt handler when using any serial
port.

The problem is that I accidentally took the tty_buffer pointer
before calling __tty_buffer_request_room(), which replaces the
buffer. This moves the pointer lookup to the right place after
allocating the new buffer space.

Subject: ata: sata_gemini: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: irqchip/gic: Ensure we have an ISB between ack and ->handle_irq

Devices that expose their interrupt status registers via system
registers (e.g. Statistical profiling, CPU PMU, DynamIQ PMU, arch timer,
vgic (although unused by Linux), ...) rely on a context synchronising
operation on the CPU to ensure that the updated status register is
visible to the CPU when handling the interrupt. This usually happens as
a result of taking the IRQ exception in the first place, but there are
two race scenarios where this isn't the case.

For example, let's say we have two peripherals (X and Y), where Y uses a
system register for its interrupt status.

Case 1:
1. CPU takes an IRQ exception as a result of X raising an interrupt
2. Y then raises its interrupt line, but the update to its system
   register is not yet visible to the CPU
3. The GIC decides to expose Y's interrupt number first in the Ack
   register
4. The CPU runs the IRQ handler for Y, but the status register is stale

Case 2:
1. CPU takes an IRQ exception as a result of X raising an interrupt
2. CPU reads the interrupt number for X from the Ack register and runs
   its IRQ handler
3. Y raises its interrupt line and the Ack register is updated, but
   again, the update to its system register is not yet visible to the
   CPU.
4. Since the GIC drivers poll the Ack register, we read Y's interrupt
   number and run its handler without a context synchronisation
   operation, therefore seeing the stale register value.

In either case, we run the risk of missing an IRQ. This patch solves the
problem by ensuring that we execute an ISB in the GIC drivers prior
to invoking the interrupt handler. This is already the case for GICv3
and EOIMode 1 (the usual case for the host).

Subject: xhci: Reset Renesas uPD72020x USB controller for 32-bit DMA issue

The Renesas uPD72020x XHCI controller seems to suffer from a really
annoying bug, where it may retain some of its DMA programming across a XHCI
reset, and despite the driver correctly programming new DMA addresses.
This is visible if the device has been using 64-bit DMA addresses, and is
then switched to using 32-bit DMA addresses.  The top 32 bits of the
address (now zero) are ignored are replaced by the 32 bits from the
*previous* programming.  Sticking with 64-bit DMA always works, but doesn't
seem very appropriate.

A PCI reset of the device restores the normal functionality, which is done
at probe time.  Unfortunately, this has to be done before any quirk has
been discovered, hence the intrusive nature of the fix.

Subject: lan78xx: USB fast connect/disconnect crash fix

USB fast connect/disconnect crash fix

When USB plugged/unplugged at fast rate,
lan78xx_mdio_init() in lan78xx_bind() failing case is not handled.
Whenever  lan78xx_mdio_init() failed, dev->mdiobus will be freed, however
since lan78xx_bind() not consider as error and try to proceed for
further initialization in lan78xx_probe() which leads system hung/crash.
Also when register_netdev() failed, netdev is freed without calling lan78xx_unbind().
Hence halting the failed cases right manner fixes the system crash/hung issue.

Subject: lan78xx: Fix to handle hard_header_len update

Fix to handle hard_header_len update

When ifconfig up/down sequence is initiated hard_header_len
get updated incrementally for each ifconfig up /down sequence,
this leads invalid hard_header_len, moving to lan78xx_bind
to have one time update of hard_header_len addresses the issue.

Subject: net: bcmgenet: drop COMPILE_TEST dependency

The last patch added the dependency on 'OF && HAS_IOMEM' but left
COMPILE_TEST as an alternative, which kind of defeats the purpose
of adding the dependency, we still get randconfig build warnings:

warning: (NET_DSA_BCM_SF2 && BCMGENET) selects MDIO_BCM_UNIMAC which has unmet direct dependencies (NETDEVICES && MDIO_BUS && HAS_IOMEM && OF_MDIO)

For compile-testing purposes, we don't really need this anyway,
as CONFIG_OF can be enabled on all architectures, and HAS_IOMEM
is present on all architectures we do meaningful compile-testing on
(the exception being arch/um).

This makes both OF and HAS_IOMEM hard dependencies.

Subject: net/mlx4_en: Fix wrong indication of Wake-on-LAN (WoL) support

Currently when WoL is supported but disabled, ethtool reports:
"Supports Wake-on: d".
Fix the indication of Wol support, so that the indication
remains "g" all the time if the NIC supports WoL.

Tested:
As accepted, when NIC supports WoL- ethtool reports:
	Supports Wake-on: g
	Wake-on: d
when NIC doesn't support WoL- ethtool reports:
        Supports Wake-on: d
        Wake-on: d

Subject: ibmvnic: Initialize SCRQ's during login renegotiation

SCRQ resources are freed during renegotiation, but they are not
re-allocated afterwards due to some changes in the initialization
process. Fix that by re-allocating the memory after renegotation.

SCRQ's can also be freed if a server capabilities request fails.
If this were encountered during a device reset for example,
SCRQ's may not be re-allocated. This operation is not necessary
anymore so remove it.

Subject: soc: qcom: GLINK SSR notifier

This driver register as a subsystem restart notifier and will send out
notifications to remote processors that has opened the "glink_ssr" GLINK
channel.

This mechanism is used to signal any GLINK participants that a 3rd party
is gone and that the communication state has to be reset; i.e. that read
and write pointers of the GLINK FIFOs are stale.

From bccf90d6e063d278b9ddc78dd266d0adef29886c Mon Sep 17 00:00:00 2001
From: Palmer Dabbelt <palmer@dabbelt.com>
Date: Fri, 23 Jun 2017 18:50:42 -0700
Subject: PCI: Add a generic weak pcibios_fixup_bus()

Multiple architectures define this as an empty function, and I'm adding
another one as part of the RISC-V port.  Add a __weak version of
pcibios_fixup_bus() and delete the now-obselete ones in a handful of
ports.

The only functional change should be that microblaze used to export
pcibios_fixup_bus().  None of the other architectures exports this, so I
just dropped it.

Subject: PCI: Add a generic weak pcibios_align_resource()

Multiple architectures define this as a trivial function, and I'm adding
another one as part of the RISC-V port.  Add a __weak version of
pcibios_align_resource() and delete the now-obselete ones in a handful of
ports.

The only functional change should be that a handful of ports used to export
pcibios_fixup_bus().  Only some architectures export this, so I just
dropped it.

Subject: arcpgu: Simplify driver name

This very minor change is still useful because it aligns
ARC PGU driver name with other DRM drivers and makes usage of
that driver name a bit easier.

For example in libdrm's test app we'll use "arcpgu" instead of
a bit more ugly "drm-arcpgu".

Subject: drm: arcpgu: Fix mmap() callback

Now that ARC properly supports DMA mmap() we can use the standard
CMA helper to map dumb buffers. This makes ARC PGU works with
standard DRM consumer applications like, for example, mpv/mplayer
via DRM. While at it, use the DEFINE_DRM_GEM_CMA_FOPS() helper.

This fixes the use of dumb buffers.

Subject: drm: arcpgu: Allow some clock deviation in crtc->mode_valid()
 callback

Currently we expect that clock driver produces the exact same value
as we are requiring. There can, and will, be some deviation
however so we need to take that into account instead of just
rejecting the mode.

According to the HDMI spec we have a max of +-0.5% for the pixel clock
frequency deviation. Lets take that into an advantage and use it to
calculate how much deviation we can support.

Subject: PCI: dwc: designware: Make dw_pcie_prog_*_atu_unroll() static

Helper functions dw_pcie_prog_*_atu_unroll() don't need to be in global
scope, so make them static.

Cleans up sparse warnings:
  - symbol 'dw_pcie_prog_outbound_atu_unroll' was not declared. Should it be static?
  - symbol 'dw_pcie_prog_inbound_atu_unroll' was not declared. Should it be static?

Subject: PCI: shpchp: Enable bridge bus mastering if MSI is enabled

An SHPC may generate MSIs to notify software about slot or controller
events (SHPC spec r1.0, sec 4.7).  A PCI device can only generate an MSI if
it has bus mastering enabled.

Enable bus mastering if the bridge contains an SHPC that uses MSI for event
notifications.

The file /sys/devices/pci000.../sriov_totalvfs is showing a wrong value.
Fix it by calling pci_sriov_set_totalvfs() to set the total number of VFs

Subject: netvsc: transparent VF management

This patch implements transparent fail over from synthetic NIC to
SR-IOV virtual function NIC in Hyper-V environment. It is a better
alternative to using bonding as is done now. Instead, the receive and
transmit fail over is done internally inside the driver.

Using bonding driver has lots of issues because it depends on the
script being run early enough in the boot process and with sufficient
information to make the association. This patch moves all that
functionality into the kernel.

Subject: rocker: Provide offload indication using nexthop flags

We want to stop using the FIB info's flags to provide the offlaod
indication and instead do that on a per-nexthop basis.

Convert rocker to do just that. It only supports one nexthop per-route,
so conversion is simple.

Subject: mlxsw: spectrum_router: Provide offload indication using nexthop
 flags

In a similar fashion to previous patch, use the nexthop flags to provide
offload indication instead of the FIB info's flags.

In case a nexthop in a multipath route can't be offloaded (gateway's MAC
can't be resolved, for example), then its offload flag isn't set.

Subject: mlxsw: spectrum_router: Don't check state when refreshing offload
 indication

Previous patch removed the reliance on the counter in the FIB info to
set the offload indication, so we no longer need to keep an offload
state on each FIB entry and can just set or unset the RTNH_F_OFFLOAD
flag in each nexthop.

This is also necessary because we're going to need to refresh the
offload indication whenever the nexthop group associated with the FIB
entry is refreshed. Current check would prevent us from marking a newly
resolved nexthop as offloaded if the FIB entry is already marked as
offloaded.

Subject: mlxsw: spectrum_router: Refresh offload indication upon group refresh

Now that we provide offload indication using the nexthop's flags we must
refresh the offload indication whenever the offload state within the
group changes.

This didn't matter until now, as offload indication was provided using
the FIB info flags and multipath routes were marked as offloaded as long
as one of the nexthops was offloaded.

Subject: crypto: inside-secure - fix invalidation check in hmac_sha1_setkey

The safexcel_hmac_sha1_setkey function checks if an invalidation command
should be issued, i.e. when the context ipad/opad change. This checks is
done after filling the ipad/opad which and it can't be true. The patch
fixes this by moving the check before the ipad/opad memcpy operations.

Subject: crypto: n2 - Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: crypto: omap-sham - remove unnecessary static in omap_sham_remove()

Remove unnecessary static on local variable dd. Such variable
is initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces the
object file size.

This issue was detected using Coccinelle and the following semantic patch:
https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci

In the following log you can see a difference in the object file size.
This log is the output of the size command, before and after the code
change:

Subject: crypto: img-hash - remove unnecessary static in img_hash_remove()

Remove unnecessary static on local variable hdev. Such variable
is initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces the
object file size.

This issue was detected using Coccinelle and the following semantic patch:
https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci

In the following log you can see a significant difference in the object
file size. This log is the output of the size command, before and after
the code change:

before:
   text    data     bss     dec     hex filename
  14842    6464     128   21434    53ba drivers/crypto/img-hash.o

after:
   text    data     bss     dec     hex filename
  14789    6376      64   21229    52ed drivers/crypto/img-hash.o

Subject: Crypto: atmel-ecc: Make a couple of local functions static

Functions atmel_ecc_i2c_client_alloc and atmel_ecc_i2c_client_free are
local to the source and no not need to be in the global scope. Make
them static.

Cleans up sparse warnings:
symbol 'atmel_ecc_i2c_client_alloc' was not declared. Should it be static?
symbol 'atmel_ecc_i2c_client_free' was not declared. Should it be static?

Subject: crypto: ccp - remove duplicate module version and author entry

commit 720419f01832 ("crypto: ccp - Introduce the AMD Secure Processor device")
moved the module registeration from ccp-dev.c to sp-dev.c but patch missed
removing the module version and author entry from ccp-dev.c.

It causes the below warning during boot when CONFIG_CRYPTO_DEV_SP_CCP=y
and CONFIG_CRYPTO_DEV_CCP_CRYPTO=y is set.

Subject: crypto: rockchip - move the crypto completion from interrupt context

It's illegal to call the completion function from hardirq context,
it will cause runtime tests to fail. Let's build a new task (done_task)
for moving update operation from hardirq context.

Subject: phy: rockchip-inno-usb2: Replace the extcon API

This patch uses the resource-managed extcon API for extcon_register_notifier()
and replaces the deprecated extcon API as following:
- extcon_get_cable_state_() -> extcon_get_state()
- extcon_set_cable_state_() -> extcon_set_state_sync()

The Asus T304UA convertible sports a magnetic detachable keyboard with
touchpad, which is connected over USB. Most of the keyboard hotkeys are
exposed through the same USB interface as the touchpad, defined in the
report descriptor as follows:

0x06, 0x31, 0xFF,  // Usage Page (Vendor Defined 0xFF31)
0x09, 0x76,        // Usage (0x76)

0xC0,              // End Collection

This UsagePage is declared as a variable, but we need to treat it as an
array to be able to map each Usage we care about to its corresponding
input key.

Subject: usb: dwc3: gadget: Correct ISOC DATA PIDs for short packets

The PIDs for Isochronous data transfers are incorrect
for high bandwidth IN endpoints when the request length
is less than EP wMaxPacketSize.

As per spec correct PIDs for ISOC data transfers are:

1) For request length <= maxpacket
	- DATA0,

2) For maxpacket < length <= (2 * maxpacket)
	- DATA1, DATA0

3) For (2 * maxpacket) <  length <= (3 * maxpacket)
	- DATA2, DATA1, DATA0.

But driver always sets PCM fields based on wMaxPacketSize
due to which DATA2 happens even for small requests.

Fix this by setting the PCM field of trb->size depending
on request length rather than fixing it to the value
depending on wMaxPacketSize.

Ideally it shouldn't give any issues as dwc3 will send
0-length packet for next IN token if host sends (even
after receiving a short packet). Windows seems to ignore
this but with MacOS frame loss observed when using f_uvc.

Subject: usb: gadget: udc: renesas_usb3: Fix usb_gadget_giveback_request()
 calling

According to the gadget.h, a "complete" function will always be called
with interrupts disabled. However, sometimes usb3_request_done() function
is called with interrupts enabled. So, this function should be held
by spin_lock_irqsave() to disable interruption. Also, this driver has
to call spin_unlock() to avoid spinlock recursion by this driver before
calling usb_gadget_giveback_request().

Subject: usb: phy: phy-msm-usb: Fix usage of devm_regulator_bulk_get()

The regulator_bulk_data pointer passed to devm_regulator_bulk_get()
is used to store the client handles for the regulators, which
is later used by devm_regulator_bulk_release() to free the
regulators.
Passing a local array as is done here means the memory used to
store the handles is freed causing the handles to be corrupted,
resulting in a crash when devm_regulator_bulk_release() tries to
free them.

Fix this my moving the array inside of the msm_otg structure.

Subject: usb: renesas_usbhs: Fix UGCTRL2 value for R-Car Gen3

The latest HW manual (Rev.0.55) shows us this UGCTRL2.VBUSSEL bit.
If the bit sets to 1, the VBUS drive is controlled by phy related
registers (called "UCOM Registers" on the manual). Since R-Car Gen3
environment will control VBUS by phy-rcar-gen3-usb2 driver,
the UGCTRL2.VBUSSEL bit should be set to 1. So, this patch fixes
the register's value. Otherwise, even if the ID pin indicates to
peripheral, the R-Car will output USBn_PWEN to 1 when a host driver
is running.

However, on course for fail3 there will be call rtl_deinit_core

For the inclusion of checking pci_iounmap this fail can be moved to

Subject: usb: renesas_usbhs: gadget: fix unused-but-set-variable warning

The commit b8b9c974afee ("usb: renesas_usbhs: gadget: disable all eps
when the driver stops") causes the unused-but-set-variable warning.
But, if the usbhsg_ep_disable() will return non-zero value, udc/core.c
doesn't clear the ep->enabled flag. So, this driver should not return
non-zero value, if the pipe is zero because this means the pipe is
already disabled. Otherwise, the ep->enabled flag is never cleared
when the usbhsg_ep_disable() is called by the renesas_usbhs driver first.

Subject: rtlwifi: Fix fallback firmware loading

Commit f70e4df2b384 ("rtlwifi: Add code to read new versions of
firmware") added code to load an old firmware file if the new one is
not available.  Unfortunately that code is never reached because
request_firmware_nowait() does not wait for the firmware to show up
and returns 0 even if the file is not there.

Use the existing fallback mechanism introduced by commit 62009b7f1279
("rtlwifi: rtl8192cu: Add new firmware") instead.

Subject: qtnfmac: updates for regulatory support

On startup driver obtains regulatory rules from firmware and
enables them during wiphy registration. Later on regulatory
domain change can be requested by host. In this case firmware
is notified about the upcoming changes. If the change is valid,
then firmware updates hardware channel configuration and host
driver receives updated channel info for each band.

Subject: qtnfmac: implement reporting current channel

Implement current channel reporting functionality. Current operating
channel can be obtained either directly using cfg80211 get_channel
callback or from stats reported by cfg80211 survey_dump callback.

Subject: qtnfmac: move current channel info from vif to mac

Wireless cfg80211 core supplies channel settings in cfg80211_ap_settings
structure for each BSS in multiple BSS configuration. On the other hand
all the virtual interfaces on one radio are using the same PHY settings
including channel.

Move chandef structure from vif to mac structure in order to mantain
the only instance of cfg80211_chan_def structure in qtnf_wmac
rather than its multiple copies in qtnf_vif.

Subject: qtnfmac: implement cfg80211 channel_switch handler

This patch implements cfg80211 channel_switch handler enabling CSA
channel-switch procedure.

Driver performs only basic validation of the requested new channel
and then sends command to firmware. Beacon IEs are not sent since
beacon update is handled by firmware.

Subject: qtnfmac: fix handling of iftype mask reported by firmware

Firmware sends supported interface type rather than mask. As a result,
types field of ieee80211_iface_limit structure may end up having
multiple iftype bits set. This leads to WARN_ON from
wiphy_verify_combinations.

Subject: qtnfmac: Tidy up DMA mask setting

As the only caller of dma_supported() outside of DMA API internals, the
qtfnmac driver stands out and invites scrutiny. Thankfully, it's not
being used for evil, but it is entirely redundant, since it open-codes a
check that the DMA mask setting functions are going to perform anyway.
In fact, the whole qtnf_pcie_init_dma_mask() function is nothing more
than a rather long-winded implementation of dma_set_mask_and_coherent(),
so let's just use that directly.

Subject: drm/fb: Fix pointer dereference before null check.

fb_crtc is used before a null check, so move the use after the null check.

This was just identified by inspection. I haven't actually observed a crash
here, so it is possible that the null check could be unnecessary.

Subject: drm/i915: add const to bin_attribute

Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file or
device_{remove/create}_bin_file. The corresponding arguments are of
type const, so declare the structures to be const.

Set the a-mpdu reference number in ath10k to make it accessible in the
receivers radiotap header. Implemented as in ath9k.  The reference number is
needed for troubleshooting and research at the receivers site (e.g. to identify
mpdu's that were aggregated in an a-mpdu)

Subject: ath10k: add initial USB support

Chipsets like QCA9377 have support for USB so add initial USB bus
support to ath10k. With this patch we have the low level HIF and
HTC protocol working and it's possible to boot the firmware,
but it's still not possible to connect or anything like.

More changes are needed for full functionality. For that reason
we print during initialisation:

WARNING: ath10k USB support is incomplete, don't expect anything to work!

Subject: ath10k: sdio: fix compile warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As suggested by Arnd Bergmann, replace
"while (time_before_...) {}"
with
"do {} while (time_before_...)"

This fixes the following warnings detected by gcc 4.1.2:

drivers/net/wireless/ath/ath10k/sdio.c: In function
‘ath10k_sdio_mbox_rxmsg_pending_handler’:
drivers/net/wireless/ath/ath10k/sdio.c:676: warning: ‘ret’ may be used uninitialized in this function

...

Subject: ath10k: extend wmi service map to accommodate new services

Though there is room to accommodate 512 services in wmi service
ready event, target uses only first 4-bits of each 32-bit word for
advertising wmi services thereby limiting max wmi services to 64.

TDLS implementation for 10.4 firmwares introduces new wmi services by
making use of remaining unused bits of each 32-bit word, therefore the
wmi service mapping in host needs to be extended.

This patch adds the logic to extend the wmi SVCMAP to accommodate new
wmi services.

Subject: ath10k: push peer type to target for TDLS peers

WMI interface for all the firmwares(except QCA6174) does not include the
type of peer(default/bss/tdls) requested during peer creation, therefore
target creates a default peer.

TDLS implementation on 10.4 firmware requires host to configure the
peer type(tdls) for TDLS peers. This patch adds peer type parameter to the
existing WMI interface for peer creation to accommodate this requirement.

Tested this change on QCA9888(10.4-3.5.1-00018) and QCA988x(10.2.4.70.9-2)
with ping tests for AP/STA modes.

Subject: ath10k: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: HID: logitech-hidpp: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.

Subject: v4l: vsp1: Add support for multiple LIF instances

The VSP2-DL instance (present in the H3 ES2.0 and M3-N SoCs) has two LIF
instances. Adapt the driver infrastructure to support multiple LIFs.
Support for multiple display pipelines will be added separately.

The change to the entity routing table removes the ability to connect
the LIF output to the HGO or HGT histogram generators. This feature is
only available on Gen2 hardware, isn't supported by the rest of the
driver, and has no known use case, so this isn't an issue.

Subject: v4l: vsp1: Add support for multiple DRM pipelines

The R-Car H3 ES2.0 VSP-DL instance has two LIF entities and can drive
two display pipelines at the same time. Refactor the VSP DRM code to
support that by introducing a vsp_drm_pipeline object that models one
display pipeline.

Subject: v4l: vsp1: Add support for header display lists in continuous mode

The VSP supports both header and headerless display lists. The latter is
easier to use when the VSP feeds data directly to the DU in continuous
mode, and the driver thus uses headerless display lists for DU operation
and header display lists otherwise.

Headerless display lists are only available on WPF.0. This has never
been an issue so far, as only WPF.0 is connected to the DU. However, on
H3 ES2.0, the VSP-DL instance has both WPF.0 and WPF.1 connected to the
DU. We thus can't use headerless display lists unconditionally for DU
operation.

Implement support for continuous mode with header display lists, and use
it for DU operation on WPF outputs that don't support headerless mode.

Subject: drm: rcar-du: Restrict DPLL duty cycle workaround to H3 ES1.x

The H3 ES1.x exhibits dot clock duty cycle stability issues. We can work
around them by configuring the DPLL to twice the desired frequency,
coupled with a /2 post-divider. This isn't needed on other SoCs and
breaks HDMI output on M3-W for a currently unknown reason, so restrict
the workaround to H3 ES1.x.

From an implementation point of view, move work around handling outside
of the rcar_du_dpll_divider() function by requesting a x2 DPLL output
frequency explicitly. The existing post-divider calculation mechanism
will then take care of dividing the clock by two automatically.

While at it, print a more useful debugging message to ease debugging
clock rate issues.

On Gen3 SoCs DPAD0 routing is configured through the last CRTC group,
unlike on Gen2 where it is configured through the first CRTC group. Fix
the driver accordingly.

Subject: drm: rcar-du: Setup planes before enabling CRTC to avoid flicker

Commit 52055bafa1ff ("drm: rcar-du: Move plane commit code from CRTC
start to CRTC resume") changed the order of the plane commit and CRTC
enable operations to accommodate the runtime PM requirements. However,
this introduced corruption in the first displayed frame, as the CRTC is
now enabled without any plane configured. On Gen2 hardware the first
frame will be black and likely unnoticed, but on Gen3 hardware we end up
starting the display before the VSP compositor, which is more
noticeable.

To fix this, revert the order of the commit operations back, and handle
runtime PM requirements in the CRTC .atomic_begin() and .atomic_enable()
helper operation handlers.

Subject: drm: rcar-du: Use the VBK interrupt for vblank events

When implementing support for interlaced modes, the driver switched from
reporting vblank events on the vertical blanking (VBK) interrupt to the
frame end interrupt (FRM). This incorrectly divided the reported refresh
rate by two. Fix it by moving back to the VBK interrupt.

Subject: drm: rcar-du: Wait for flip completion instead of vblank in commit
 tail

Page flips can take more than one vertical blanking to complete if
arming the page flips races with the vertical blanking interrupt.
Waiting for one vblank to complete the atomic commit in the commit tail
handler is thus incorrect, and can lead to framebuffers being released
while still being scanned out.

Fix this by waiting for flip completion instead, using the
drm_atomic_helper_wait_for_flip_done() helper.

Subject: drm: rcar-du: Fix race condition when disabling planes at CRTC stop

When stopping the CRTC the driver must disable all planes and wait for
the change to take effect at the next vblank. Merely calling
drm_crtc_wait_one_vblank() is not enough, as the function doesn't
include any mechanism to handle the race with vblank interrupts.

Replace the drm_crtc_wait_one_vblank() call with a manual mechanism that
handles the vblank interrupt race.

Subject: drm: rcar-du: Repair vblank for DRM page flips using the VSP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver recently switched from handling page flip completion in the
DU vertical blanking handler to the VSP frame end handler to fix a race
condition. This unfortunately resulted in incorrect timestamps in the
vertical blanking events sent to userspace as vertical blanking is now
handled after sending the event.

To fix this we must reverse the order of the two operations. The easiest
way is to handle vertical blanking in the VSP frame end handler before
sending the event. The VSP frame end interrupt occurs approximately 50µs
earlier than the DU frame end interrupt, but this should not cause any
undue harm.

As we need to handle vertical blanking even when page flip completion is
delayed, the VSP driver now needs to call the frame end completion
callback unconditionally, with a new argument to report whether page
flip has completed.

With this new scheme the DU vertical blanking interrupt isn't needed
anymore, so we can stop enabling it.

Subject: drm: rcar-du: Use new iterator macros

for_each_obj_in_state is about to be removed, so use the correct new
iterator macros.

Also look at new_plane_state instead of plane->state when looking up
the hw planes in use. They should be the same except when reallocating,
(in which case this code is skipped) and we should really stop looking
at obj->state whenever possible.

Subject: drm/atmel-hlcdc : constify drm_plane_helper_funcs and
 drm_plane_funcs.

drm_plane_helper_funcs and drm_plane_funcsare not supposed to change
at runtime. All functions working with drm_plane_helper_funcs and
drm_plane_funcs work with const. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   6072	    596	      0	   6668	   1a0c atmel_hlcdc_plane.o

File size After adding 'const':

Subject: drm/atmel-hlcdc: switch to drm_*{get,put} helpers

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to use
the new APIs.

Subject: mtd: nand: Remove support for block locking/unlocking

Commit 7d70f334ad2b ("mtd: nand: add lock/unlock routines") introduced
support for the Micron LOCK/UNLOCK commands but no one ever used the
nand_lock/unlock() functions.

Remove support for these vendor-specific operations from the core. If
one ever wants to add them back they should be put in nand_micron.c and
mtd->_lock/_unlock should be directly assigned from there instead of
exporting the functions.

Subject: net: hns: Add self-adaptive interrupt coalesce support in hns driver

When deal with low and high throughput, it is hard to achiece both
high performance and low latency. In order to achiece that, this patch
calculates the rx rate, and adjust the interrupt coalesce parameter
accordingly.

Subject: qlcnic: add const to bin_attribute structure

Add const to bin_attribute structure as it is only passed to the
functions sysfs_{remove/create}_bin_file. The corresponding
arguments are of type const, so declare the structure to be const.

Subject: net: dsa: bcm_sf2: dst in not an array

It's been a while now since ds->dst is not an array anymore, but a
simple pointer to a dsa_switch_tree.

Fortunately, SF2 does not support multi-chip and thus ds->index is
always 0.

This patch substitutes 'ds->dst[ds->index].' with 'ds->dst->'.

We were reserving fewer dwords in the ring than necessary. Indeed
we're always writing all registers once, so discard the actual number
of registers given by the user and just program the whitelisted ones
once.

Subject: drm/i915/perf: prune OA configs

In the following commit we'll introduce loadable userspace
configs. This change reworks how configurations are handled in the
perf driver and retains only the test configurations in kernel space.

We now store the test config in dev_priv and resolve the id only once
when opening the perf stream. The OA config is then handled through a
pointer to the structure holding the configuration details.

v2: Rework how test configs are handled (Lionel)

v3: Use u32 to hold number of register (Matthew)

v4: Removed unused dev_priv->perf.oa.current_config variable (Matthew)

v5: Lock device when accessing exclusive_stream (Lionel)

v6: Ensure OACTXCONTROL is always reprogrammed (Lionel)

v7: Switch a couple of index variable from int to u32 (Matthew)

configs.

From f89823c212246d0671cc51e69894a3df1a743aee Mon Sep 17 00:00:00 2001
From: Lionel Landwerlin <lionel.g.landwerlin@intel.com>
Date: Thu, 3 Aug 2017 18:05:50 +0100
Subject: drm/i915/perf: Implement I915_PERF_ADD/REMOVE_CONFIG interface

The motivation behind this new interface is expose at runtime the
creation of new OA configs which can be used as part of the i915 perf
open interface. This will enable the kernel to learn new configs which
may be experimental, or otherwise not part of the core set currently
available through the i915 perf interface.

v2: Drop DRM_ERROR for userspace errors (Matthew)
    Add padding to userspace structure (Matthew)
    s/guid/uuid/ (Matthew)

v3: Use u32 instead of int to iterate through registers (Matthew)

v4: Lock access to dynamic config list (Lionel)

v5: by Matthew:
    Fix uninitialized error values
    Fix incorrect unwiding when opening perf stream
    Use kmalloc_array() to store register
    Use uuid_is_valid() to valid config uuids
    Declare ioctls as write only
    Check padding members are set to 0
    by Lionel:
    Return ENOENT rather than EINVAL when trying to remove non
    existing config

v6: by Chris:
    Use ref counts for OA configs
    Store UUID in drm_i915_perf_oa_config rather then using pointer
    Shuffle fields of drm_i915_perf_oa_config to avoid padding

v7: by Chris
    Rename uapi pointers fields to end with '_ptr'

v8: by Andrzej, Marek, Sebastian
    Update register whitelisting
    by Lionel
    Add more register names for documentation
    Allow configuration programming in non-paranoid mode
    Add support for value filter for a couple of registers already
    programmed in other part of the kernel

v9: Documentation fix (Lionel)
    Allow writing WAIT_FOR_RC6_EXIT only on Gen8+ (Andrzej)

v10: Perform read access_ok() on register pointers (Lionel)

From f461bd2b494bdf27ed7f9ea03101f7119ed7c695 Mon Sep 17 00:00:00 2001
From: David Lechner <david@lechnology.com>
Date: Thu, 3 Aug 2017 11:19:08 -0500
Subject: drm/fb-helper: add new drm_setup_crtcs_fb() function

This adds a new drm_setup_crtcs_fb() function to handle the parts of
drm_setup_crtcs() that touch fb_helper->fb and fb_helper->fbdev. When
drm_setup_crtcs() is called during initialization, these fields are NULL
because they have not been allocated yet.

There is currently a hack at the end of drm_fb_helper_single_fb_probe()
that sets fb_helper->fb, so it is moved to the new drm_setup_crtcs_fb()
function.

This is also done in preparation for addition setup that requires access
to fb_helper->fbdev.

Subject: drm/i915: Fix PCH names for KBP and CNP.

No functional change.

KBP was based on SPT and spec wasn't clear about the full name.
There was the initial point of the "Point" confusion.

Later the split with Coffee Lake and Cannon Lake both using CNP
and also some uncertainty from the specs we had at that time
made us to propagated the mistake along.

So, let's fix this now and avoid propagating these wrong
"points".

Subject: drm/i915: enable WaDisableDopClkGating for skl

This WA is required when decoupled frequencies for slice and unslice
are enabled. This disables DOP clock gating for skl.

v2: enable the WA for all gen9 platforms (not just for SKL GT4 where
    the hang issue is originally reported) to avoid rare hangs (David)
v3: as per WaDatabase, enable it only for SKL (Rodrigo)

In several dwc-based drivers, ->host_init() can fail, so make sure to
propagate and handle this to avoid continuing operation of a driver or

Subject: treewide: Consolidate Apple DMI checks

We're about to amend ACPI bus scan with DMI checks whether we're running
on a Mac to support Apple device properties in AML.  The DMI checks are
performed for every single device, adding overhead for everything x86
that isn't Apple, which is the majority.  Rafael and Andy therefore
request to perform the DMI match only once and cache the result.

Outside of ACPI various other Apple DMI checks exist and it seems
reasonable to use the cached value there as well.  Rafael, Andy and
Darren suggest performing the DMI check in arch code and making it
available with a header in include/linux/platform_data/x86/.

To this end, add early_platform_quirks() to arch/x86/kernel/quirks.c
to perform the DMI check and invoke it from setup_arch().  Switch over
all existing Apple DMI checks, thereby fixing two deficiencies:

* They are now #defined to false on non-x86 arches and can thus be
  optimized away if they're located in cross-arch code.

* Some of them only match "Apple Inc." but not "Apple Computer, Inc.",
  which is used by BIOSes released between January 2006 (when the first
  x86 Macs started shipping) and January 2007 (when the company name
  changed upon introduction of the iPhone).

Subject: ACPI / property: Don't evaluate objects for devices w/o handle

Fabricated devices such as LNXPWRBN lack a handle, causing evaluation
of _CCA and _DSD to always fail with AE_BAD_PARAMETER.  While that is
merely a (negligible) waste of processing power, evaluating a _DSM for
them (such as Apple's device properties _DSM which we're about to add)
results in an ugly error:

    ACPI: \: failed to evaluate _DSM (0x1001)

Avoid by not evaluating _DSD and the upcoming _DSM for devices without
handle.

Subject: ACPI / property: Support Apple _DSM properties
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While the rest of the world has standardized on _DSD as the way to store
device properties in AML (introduced with ACPI 5.1 in 2014), Apple has
been using a custom _DSM to achieve the same for much longer (ever since
they switched from DeviceTree-based PowerPC to Intel in 2005, verified
with MacOS X 10.4.11).

The theory of operation on macOS is as follows:  AppleACPIPlatform.kext
invokes mergeEFIproperties() and mergeDSMproperties() for each device to
merge properties conveyed by EFI drivers as well as properties stored in
AML into the I/O Kit registry from which they can be retrieved by
drivers.  We've been supporting EFI properties since commit 58c5475aba67
("x86/efi: Retrieve and assign Apple device properties").  The present
commit adds support for _DSM properties, thereby completing our support
for Apple device properties.  The _DSM properties are made available
under the primary fwnode, the EFI properties under the secondary fwnode.
So for devices which possess both property types, they can all be
elegantly accessed with the uniform API in <linux/property.h>.

Until recently we had no need to support _DSM properties, they contained
only uninteresting garbage.  The situation has changed with MacBooks and
MacBook Pros introduced since 2015:  Their keyboard is attached with SPI
instead of USB and the _CRS data which is necessary to initialize the
spi driver only contains valid information if OSPM responds "false" to
_OSI("Darwin").  If OSPM responds "true", _CRS is empty and the spi
driver fails to initialize.  The rationale is very simple, Apple only
cares about macOS and Windows:  On Windows, _CRS contains valid data,
whereas on macOS it is empty.  Instead, macOS gleans the necessary data
from the _DSM properties.

Since Linux deliberately defaults to responding "true" to _OSI("Darwin"),
we need to emulate macOS' behaviour by initializing the spi driver with
data returned by the _DSM.

An out-of-tree driver for the SPI keyboard exists which currently binds
to the ACPI device, invokes the _DSM, parses the returned package and
instantiates an SPI device with the data gleaned from the _DSM:
https://github.com/cb22/macbook12-spi-driver/commit/9a416d699ef4
https://github.com/cb22/macbook12-spi-driver/commit/0c34936ed9a1

By adding support for Apple's _DSM properties in generic ACPI code, the
out-of-tree driver will be able to register as a regular SPI driver,
significantly reducing its amount of code and improving its chances to
be mainlined.

The SPI keyboard will not be the only user of this commit:  E.g. on the
MacBook8,1, the UART-attached Bluetooth device likewise returns empty
_CRS data if OSPM returns "true" to _OSI("Darwin").

The _DSM returns a Package whose format unfortunately deviates slightly
from the _DSD spec:  The properties are marshalled up in a single Package
as alternating key/value elements, unlike _DSD which stores them as a
Package of 2-element Packages.  The present commit therefore converts
the Package to _DSD format and the ACPI core can then treat the data as
if Apple would follow the standard.

Well, except for one small annoyance:  The properties returned by the
_DSM only ever have one of two types, Integer or Buffer.  The former is
retrievable as usual with device_property_read_u64(), but the latter is
not part of the _DSD spec and it is not possible to retrieve Buffer
properties with the device_property_read_*() functions due to the type
checking performed in drivers/acpi/property.c.  It is however possible
to retrieve them with acpi_dev_get_property().  Apple is using the
Buffer type somewhat sloppily to store null-terminated strings but also
integers.  The real data type is not distinguishable by the ACPI core
and the onus is on the caller to use the contents of the Buffer in an
appropriate way.

In case Apple moves to _DSD in the future, this commit first checks for
_DSD and falls back to _DSM only if _DSD is not found.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SPI and I2C slaves are enumerated by their respective parents rather
than the ACPI core.  They are recognized by presence of _CRS resources,
which however are missing on Macs.  Check for presence of device
properties instead.

Subject: spi: Use Apple device properties in absence of ACPI resources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MacBooks and MacBook Pros introduced since 2015 return empty _CRS data
for SPI slaves, causing device initialization to fail.  Most of the
information that would normally be conveyed via _CRS is available
through ACPI device properties instead, so take advantage of them.

The meaning and appropriate usage of the device properties was reverse
engineered by Ronald Tschalär and carried over from these commits
authored by him:

https://github.com/cb22/macbook12-spi-driver/commit/9a416d699ef4
https://github.com/cb22/macbook12-spi-driver/commit/0c34936ed9a1

According to Ronald, the device properties have the following meaning:

spiSclkPeriod   /* period in ns */
spiWordSize     /* in number of bits */
spiBitOrder     /* 1 = MSB_FIRST, 0 = LSB_FIRST */
spiSPO          /* clock polarity: 0 = low, 1 = high */
spiSPH          /* clock phase: 0 = first, 1 = second */
spiCSDelay      /* delay between cs and receive on reads in 10 us */
resetA2RUsec    /* active-to-receive delay? */
resetRecUsec    /* receive delay? */

Functions working with attribute_groups provided by <linux/sysfs.h>
work with const attribute_group. These attribute_group structures do not
change at runtime so mark them as const.

File size before:

 7998      3432      64   11494    2ce6 drivers/acpi/dock.o

This change was made with the help of Coccinelle.

Subject: ACPICA: Divergences: reduce access size definitions

ACPICA commit cf27b3c98883d2a15d932016792fcb8272ace96d

The following commit introduces definition of access width to ACPICA.
  Commit: 2bece49394872d36bbc5767fd643deac05920c55
  Subject: ACPI: SPCR: Use access width to determine mmio usage

Actually the access bit width can be calculated via access width. It
would be better to define a macro calculating bit width rather than
defining fixed values. This patch thus cleans up the definitions to
reduce divergences.

Subject: ACPICA: CLib: Add short multiply/shift support

ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5

In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit
multiply/shift supports are also required to be implemented. Otherwise,
MSVC complains:
 acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul
 acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr

Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
   different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.

This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng.

For Linux kernel, this patch is a functional no-op.

Subject: ACPICA: EFI/EDK2: Cleanup to enable /WX for MSVC builds

ACPICA commit a7c6d65a5dab20b1e191c197e09af337fc54b341

/WX turns warning into fatal erros for MSVC builds. We need /WX- during
EDK2 porting to allow agile development.

Now it is time to enable /WX and some explicit type conversion cleanups
are required for enabling /WX. Lv Zheng.

Subject: ACPICA: Interpreter: Update handling for Alias operator

ACPICA commit 719d0bdd48e3e8e7a62a86c04922b9f41da6def0

Provide common creation code for the Alias operator. All objects
are now handled the same, with the only exception being the
Method() operator. It has a special internal Alias type.

Subject: ACPICA: Implement deferred resolution of reference package elements

ACPICA commit 0c08790c56fdf0dc081ae869495a09d8c4230854

This change defers the resolution of package elements that
are named references until after the entire namespace has been
loaded from the definition block. This allows such references
to be in fact forward references for both module level code
and control methods.

Subject: ACPICA: Resources: Allow _DMA method in walk resources

ACPICA commit af661c00afac7aa481a961fa48c6540a99ad64a6

The _DMA object contains a resource template, this change
adds support for the walk resources function so that ACPI
devices containing a _DMA object can actually parse it to
detect DMA ranges for the respective bus.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting

explicitly state whether the driver needs exclusive or shared reset control
behavior. Convert all drivers requesting exclusive resets to the explicit
API call so the temporary transition helpers can be removed.

Subject: PCI: vmd: Assign vector zero to all bridges

We don't want slower IRQ handlers impacting faster devices that happen to
be assigned the same VMD interrupt vector. The driver was trying to
separate such devices by checking if MSI-X wasn't used, but really we just
don't want endpoint devices to share with bridges. Most bridges may use MSI
currently, so that criteria happened to work, but newer ones may use MSI-X,
so this patch explicitly checks the device type when choosing a vector.

host_init() should detect and propagate errors from post_init().

In addition, by acknowledging that post_init() can fail we must disable the
post_init() resources in a step separate from the deinit, so that we don't
try to disable the post_init() resources a second time.

Subject: net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC

This patch adds the support of Hisilicon Network Subsystem 3
Ethernet driver to hip08 family of SoCs.

This driver includes basic Rx/Tx functionality. It also includes
the client registration code with the HNAE3(Hisilicon Network
Acceleration Engine 3) framework.

This work provides the initial support to the hip08 SoC and
would incrementally add features or enhancements.

Subject: net: hns3: Add support of the HNAE3 framework

This patch adds the support of the HNAE3 (Hisilicon Network
Acceleration Engine 3) framework support to the HNS3 driver.

Framework facilitates clients like ENET(HNS3 Ethernet Driver), RoCE
and user-space Ethernet drivers (like ODP etc.) to register with HNAE3
devices and their associated operations.

From 68c0a5c70614ce0adf8c6ff849534dd6d2c0ca43 Mon Sep 17 00:00:00 2001
From: Salil <salil.mehta@huawei.com>
Date: Wed, 2 Aug 2017 16:59:47 +0100
Subject: net: hns3: Add HNS3 IMP(Integrated Mgmt Proc) Cmd Interface Support

This patch adds the support of IMP (Integrated Management Processor)
command interface to the HNS3 driver.

Each PF/VF has support of CQP(Command Queue Pair) ring interface.
Each CQP consis of send queue CSQ and receive queue CRQ.
There are various commands a PF/VF may support, like for Flow Table
manipulation, Device management, Packet buffer allocation, Forwarding,
VLANs config, Tunneling/Overlays etc.

This patch contains code to initialize the command queue, manage the
command queue descriptors and Rx/Tx protocol with the command processor
in the form of various commands/results and acknowledgements.

Subject: net: hns3: Add support of TX Scheduler & Shaper to HNS3 driver

THis patch adds the support of the Scheduling and Shaping
functionalities during the transmit leg. This also adds the
support of Pause at MAC level. (Pause at per-priority level
shall be added later along with the DCB feature).

Hardware as such consists of two types of cofiguration of 6 level
schedulers. Algorithms varies according to the level and type
of scheduler being used. Current patch is used to initialize
the mapping, algorithms(like SP, DWRR etc) and shaper(CIR, PIR etc)
being used.

Subject: net: hns3: Add Ethtool support to HNS3 driver

This patch adds the support of the Ethtool interface to
the HNS3 Ethernet driver. Various commands to read the
statistics, configure the offloading, loopback selftest etc.
are supported.

Subject: ACPI: Make acpi_dev_get_resources() method agnostic

The function acpi_dev_get_resources() is completely generic and
can be used to parse resource objects that are not necessarily
coming from the _CRS method but also from other objects eg _DMA
that have the same _CRS resource format.

Create an acpi_dev_get_resources() helper, internal to the ACPI
resources parsing compilation unit, __acpi_dev_get_resources(),
that takes a const char* parameter to detect which ACPI method should be
called to retrieve the resources list and make acpi_dev_get_resources()
call it with a method name _CRS leaving the API behaviour unchanged.

Subject: net: mvpp2: introduce per-port nrxqs/ntxqs variables

Currently, the global variables rxq_number and txq_number hold the
number of per-port TXQs and RXQs. Until now, such numbers were
constant regardless of the driver configuration. As we are going to
introduce different modes for TX and RX queues, these numbers will
depend on the configuration (PPv2.1 vs. PPv2.2, exact queue
distribution logic).

Therefore, as a preparation, we move the number of RXQs and TXQs in
the 'struct mvpp2_port' structure, next to the RXQs and TXQs
descriptor arrays.

For now, they remain initialized to the same default values as
rxq_number/txq_number used to be initialized, but this will change in
future commits.

The only non-mechanical change in this patch is that the check to
verify hardware constraints on the number of RXQs and TXQs is moved
from mvpp2_probe() to mvpp2_port_probe(), since it's now in
mvpp2_port_probe() that we initialize the per-port count of RXQ and
TXQ.

Subject: net: mvpp2: move from cpu-centric naming to "software thread" naming

The PPv2.2 IP has a concept of "software thread", with all registers
of the PPv2.2 mapped 8 times, for concurrent accesses by 8 "software
threads". In addition, interrupts on RX queues are associated to such
"software thread".

For most cases, we map a "software thread" to the more conventional
concept of CPU, but we will soon have one exception: we will have a
model where we have one TX interrupt per CPU (each using one software
thread), and all RX events mapped to another software thread
(associated to another interrupt).

In preparation for this change, it makes sense to change the naming
from MVPP2_MAX_CPUS to MVPP2_MAX_THREADS, and plan for 8 software
threads instead of 4 currently.

Subject: net: mvpp2: introduce queue_vector concept

In preparation to the introduction of TX interrupts and improved RX
queue distribution, this commit introduces the concept of "queue
vector". A queue vector represents a number of RX and/or TX queues,
and an associated NAPI instance and interrupt.

This commit currently only creates a single queue_vector, so there are
no changes in behavior, but it paves the way for additional
queue_vector in the next commits.

From 213f428f5056affa627056a5953eec58e3adf5a3 Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Subject: net: mvpp2: add support for TX interrupts and RX queue distribution
 modes

This commit adds the support for two related features:

 - Support for TX interrupts, with one interrupt for each CPU

 - Support for different RX queue distribution modes
   MVPP2_QDIST_SINGLE_MODE where a single interrupt, shared by all
   CPUs, receives the RX events, and MVPP2_QDIST_MULTI_MODE, where the
   per-CPU interrupts used for TX events are also used for RX events.

Since additional interrupts are needed, an update to the Device Tree
binding is needed. However, backward compatibility is preserved with
the old Device Tree binding, by gracefully degrading to the original
behavior, with only one RX interrupt, and TX completion being handled
by an hrtimer.

From 04b1d4e50e82536c12da00ee04a77510c459c844 Mon Sep 17 00:00:00 2001
From: Ido Schimmel <idosch@mellanox.com>
Date: Thu, 3 Aug 2017 13:28:11 +0200
Subject: net: core: Make the FIB notification chain generic

The FIB notification chain is currently soley used by IPv4 code.
However, we're going to introduce IPv6 FIB offload support, which
requires these notification as well.

As explained in commit c3852ef7f2f8 ("ipv4: fib: Replay events when
registering FIB notifier"), upon registration to the chain, the callee
receives a full dump of the FIB tables and rules by traversing all the
net namespaces. The integrity of the dump is ensured by a per-namespace
sequence counter that is incremented whenever a change to the tables or
rules occurs.

In order to allow more address families to use the chain, each family is
expected to register its fib_notifier_ops in its pernet init. These
operations allow the common code to read the family's sequence counter
as well as dump its tables and rules in the given net namespace.

Additionally, a 'family' parameter is added to sent notifications, so
that listeners could distinguish between the different families.

Implement the common code that allows listeners to register to the chain
and for address families to register their fib_notifier_ops. Subsequent
patches will implement these operations in IPv6.

In the future, ipmr and ip6mr will be extended to provide these
notifications as well.

Subject: mlxsw: spectrum_router: Demultiplex FIB event based on family

The FIB notification block currently only handles IPv4 events, but we
want to start handling IPv6 events soon, so lay the groundwork now.

Do that by preparing the work item and process it according to the
notified address family.

Subject: mlxsw: spectrum_router: Add support for IPv6 routes addition /
 deletion

Allow directly connected and remote unicast IPv6 routes to be programmed
to the device's tables.

As with IPv4, identical routes - sharing the same destination prefix -
are ordered in a FIB node according to their table ID and then the
metric. While the kernel doesn't share the same trie for the local and
main table, this does happen in the device, so ordering according to
table ID is needed.

Since individual nexthops can be added and deleted in IPv6, each FIB
entry stores a linked list of the rt6_info structs it represents. Upon
the addition or deletion of a nexthop, a new nexthop group is allocated
according to the new configuration and the old one is destroyed.
Identical groups aren't currently consolidated, but will be in a
follow-up patchset.

Subject: mlxsw: spectrum_router: Add support for route replace

In case we got a replace event, then the replaced route must exist. If
the route isn't capable of multipath, then replace first matching
non-multipath capable route.

If the route is capable of multipath and matching multipath capable
route is found, then replace it. Otherwise, replace first matching
non-multipath capable route.

The new route is inserted before the replaced one. In case the replaced
route is currently offloaded, then it's overwritten in the device's table
by the new route and later deleted, thus not impacting routed traffic.

Subject: mlxsw: spectrum_router: Abort on source-specific routes

Without resorting to ACLs, the device performs route lookup solely based
on the destination IP address.

In case source-specific routing is needed, an error is returned and the
abort mechanism is activated, thus allowing the kernel to take over
forwarding decisions.

Instead of aborting, we can trap specific destination prefixes where
source-specific routes are present, but this will result in a lot more
code that is unlikely to ever be used.

error is reported when doing SR-IOV hotplug with kernel built with lockdep:

The workaround is to poll for host response instead of blocking on

Subject: initcall_debug: add deferred probe times

initcall_debug attributes all deferred device probe retries for the
late_initcall level to function deferred_probe_initcall.  Add logs of
the individual device probe routines called, to identify which drivers
are executing for how long during the initcall path.  Deferred probes
that occur after initcall processing are not shown.

Example log messages added:

[    0.505119] deferred probe my-sound-device @ 6
[    0.517656] deferred probe my-sound-device returned after 1227 usecs

Subject: crypto: algapi - make crypto_xor() take separate dst and src
 arguments

There are quite a number of occurrences in the kernel of the pattern

  if (dst != src)
          memcpy(dst, src, walk.total % AES_BLOCK_SIZE);
  crypto_xor(dst, final, walk.total % AES_BLOCK_SIZE);

or

  crypto_xor(keystream, src, nbytes);
  memcpy(dst, keystream, nbytes);

where crypto_xor() is preceded or followed by a memcpy() invocation
that is only there because crypto_xor() uses its output parameter as
one of the inputs. To avoid having to add new instances of this pattern
in the arm64 code, which will be refactored to implement non-SIMD
fallbacks, add an alternative implementation called crypto_xor_cpy(),
taking separate input and output arguments. This removes the need for
the separate memcpy().

Subject: crypto: ccp - Rework the unit-size check for XTS-AES

The CCP supports a limited set of unit-size values. Change the check
for this parameter such that acceptable values match the enumeration.
Then clarify the conditions under which we must use the fallback
implementation.

I've been waing a long time for the generic sideband driver to
appear. Patience has run out, so include the minimum here to
just read registers.

Subject: clk: sunxi-ng: h3: gate then ungate PLL CPU clk after rate change

This patch utilizes the new PLL clk notifier to gate then ungate the
PLL CPU clock after rate changes. This should prevent any system hangs
resulting from cpufreq changes to the clk.

Subject: clk: sunxi-ng: allow set parent clock (PLL_CPUX) for CPUX clock on H3

The CPUX clock, which is the main clock of the ARM core on Allwinner H3,
can be adjusted by changing the frequency of the PLL_CPUX clock.

Allowing setting parent clock for the CPUX clock, thus the PLL_CPUX
clock can be adjusted when adjusting the CPUX clock.

Subject: sock: enable MSG_ZEROCOPY

Prepare the datapath for refcounted ubuf_info. Clone ubuf_info with
skb_zerocopy_clone() wherever needed due to skb split, merge, resize
or clone.

Split skb_orphan_frags into two variants. The split, merge, .. paths
support reference counted zerocopy buffers, so do not do a deep copy.
Add skb_orphan_frags_rx for paths that may loop packets to receive
sockets. That is not allowed, as it may cause unbounded latency.
Deep copy all zerocopy copy buffers, ref-counted or not, in this path.

The exact locations to modify were chosen by exhaustively searching
through all code that might modify skb_frag references and/or the
the SKBTX_DEV_ZEROCOPY tx_flags bit.

The changes err on the safe side, in two ways.

(1) legacy ubuf_info paths virtio and tap are not modified. They keep
    a 1:1 ubuf_info to sk_buff relationship. Calls to skb_orphan_frags
    still call skb_copy_ubufs and thus copy frags in this case.

(2) not all copies deep in the stack are addressed yet. skb_shift,
    skb_split and skb_try_coalesce can be refined to avoid copying.
    These are not in the hot path and this patch is hairy enough as
    is, so that is left for future refinement.

Iommu would get page fault with following path:

   vop_enable:

         save current vop registers to vop->regsbak, then you can found
         window is enable on regsbak.
      2, VOP_WIN_SET(vop, win, gate, 1);
         force enable window gate, but gate and enable are on same
         hardware register, then window enable bit rewrite to vop hardware.
      3, vop power on, and vop might try to scan destroyed buffer,
         then iommu get page fault.

Move windows disable after vop regsbak restore, then vop regsbak mechanism
would keep tracing the modify, everything would be safe.

According to the kerneldoc[0], should do fbdev setup before calling
drm_kms_helper_poll_init(), otherwise, Kms hotplug event may race
into fbdev helper initial, and fb_helper->dev may be NULL pointer,
that would cause the bug:

Subject: drm: amd: remove dead code and pointless local lut storage

The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code and hook up the crtc .gamma_set
to use the crtc gamma_store directly instead of duplicating that
info locally.

Subject: drm: i915: remove dead code and pointless local lut storage

The driver stores lut values from the fbdev interface, and is able
to give them back, but does not appear to do anything with these
lut values. The generic fb helpers have replaced this function,
and may even have made the driver work for the C8 mode from the
fbdev interface. But that is untested.

Since the fb helpers .gamma_set and .gamma_get are obsolete,
remove the dead code.

Subject: drm: radeon: remove dead code and pointless local lut storage

The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code and hook up the crtc .gamma_set
to use the crtc gamma_store directly instead of duplicating that
info locally.

Subject: drm: stm: remove dead code and pointless local lut storage

The redundant fb helper .load_lut is no longer used, and can not
work right without also providing the fb helpers .gamma_set and
.gamma_get thus rendering the code in this driver suspect.

Just remove the dead code.

Subject: drm/i915/gvt: Initialize MMIO Block with HW state

MMIO block with tracked mmio, is introduced for the sake of performance
of searching tracked mmio. All the tracked mmio needs to get the initial
value from the HW state during vGPU being created. This patch is to
initialize the tracked registers in MMIO block with the HW state.

v2: Add "Fixes:" line for this patch (Zhenyu)

Fixes: 65f9f6febf12 ("drm/i915/gvt: Optimize MMIO register handling for some large MMIO blocks")

Subject: iommu/exynos: prevent building on big-endian kernels

Since we print the correct warning, an allmodconfig build is no longer
clean but always prints it, which defeats compile-testing:

drivers/iommu/exynos-iommu.c:58:2: error: #warning "revisit driver if we can enable big-endian ptes" [-Werror=cpp]

This replaces the #warning with a dependency, moving warning text into
a comment.

Subject: iommu/omap: Fix disabling of MMU upon a fault

The IOMMU framework lets its client users be notified on a
MMU fault and allows them to either handle the interrupt by
dynamic reloading of an appropriate TLB/PTE for the offending
fault address or to completely restart/recovery the device
and its IOMMU.

The OMAP remoteproc driver performs the latter option, and
does so after unwinding the previous mappings. The OMAP IOMMU
fault handler however disables the MMU and cuts off the clock
upon a MMU fault at present, resulting in an interconnect abort
during any subsequent operation that touches the MMU registers.

So, disable the IP-level fault interrupts instead of disabling
the MMU, to allow continued MMU register operations as well as
to avoid getting interrupted again.

Subject: iommu/omap: Use DMA-API for performing cache flushes

The OMAP IOMMU driver was using ARM assembly code directly for
flushing the MMU page table entries from the caches. This caused
MMU faults on OMAP4 (Cortex-A9 based SoCs) as L2 caches were not
handled due to the presence of a PL310 L2 Cache Controller. These
faults were however not seen on OMAP5/DRA7 SoCs (Cortex-A15 based
SoCs).

The OMAP IOMMU driver is adapted to use the DMA Streaming API
instead now to flush the page table/directory table entries from
the CPU caches. This ensures that the devices always see the
updated page table entries. The outer caches are now addressed
automatically with the usage of the DMA API.

In the commit 3c8f4ad85c4b ("memory/mediatek: add support for mt2701"),
the larb->larbid was added but not initialized.
Mediatek's gen1 smi need this hardware larbid information to get the
register offset which controls whether enable iommu for this larb.
This patch add the initialize routine for larbid.

Subject: iommu/exynos: Remove custom platform device registration code

Commit 09515ef5ddad ("of/acpi: Configure dma operations at probe time for
platform/amba/pci bus devices") postponed the moment of attaching IOMMU
controller to its device, so there is no need to register IOMMU controllers
very early, before all other devices in the system. This change gives us an
opportunity to use standard platform device registration method also for
Exynos SYSMMU controllers.

Subject: cpufreq: intel_pstate: Improve IO performance with per-core P-states

In the current implementation, the response latency between seeing
SCHED_CPUFREQ_IOWAIT set and the actual P-state adjustment can be up
to 10ms.  It can be reduced by bumping up the P-state to the max at
the time SCHED_CPUFREQ_IOWAIT is passed to intel_pstate_update_util().
With this change, the IO performance improves significantly.

For a simple "grep -r . linux" (Here linux is the kernel source
folder) with caches dropped every time on a Broadwell Xeon workstation
with per-core P-states, the user and system time is shorter by as much
as 30% - 40%.

The same performance difference was not observed on clients that don't
support per-core P-state.

Subject: drm/i915/shrinker: Wrap need_resched() inside preempt-disable

In order for us to successfully detect the end of a timeslice,
preemption must be disabled. Otherwise, inside the loop we may be
preempted many times without our noticing, and each time our timeslice
will be reset, invalidating need_resched()

Subject: drm/i915: fix backlight invert for non-zero minimum brightness

When we started following the backlight minimum brightness in
6dda730e55f4 ("drm/i915: respect the VBT minimum backlight brightness")
we overlooked the brightness invert quirk. Even if we invert the
brightness, we need to take the min limit into account. We probably
missed this because the invert has only been required on gen4 for proper
operation.

Subject: drm/bridge: dw-hdmi: add better clock disable control

The video setup path aways sets the clock disable register to a specific
value, which has the effect of disabling the CEC engine.  When we add the
CEC driver, this becomes a problem.

Fix this by only setting/clearing the bits that the video path needs to.

meson8b clock driver gracefully handles case where the clkid is defined
but the clock hw pointer is not provided, as long as it is not at the end

This patch ensure that the last entries are defined as well to handle
this particular case.

Subject: clk: meson: meson8b: register the built-in reset controller

The clock controller also includes some reset lines. This patch
implements a reset controller to assert and de-assert these resets.
The reset controller itself is registered early (through
CLK_OF_DECLARE_DRIVER) because it is needed very early in the boot
process (to start the secondary CPU cores).

According to the public S805 datasheet there are two more reset bits
in the HHI_SYS_CPU_CLK_CNTL0 register, which are not implemented by
this patch (as these seem to be unused in Amlogic's vendor Linux kernel
sources and their u-boot tree):
- bit 15: GEN_DIV_SOFT_RESET
- bit 14: SOFT_RESET

All information was taken from the public S805 Datasheet and Amlogic's
vendor GPL kernel sources. This patch is based on an earlier version
submitted by Carlo Caione.

Subject: clk: meson: gxbb: Add sd_emmc clk0 clocks

Input source 0 of the mmc controllers is not directly xtal, as currently
described in DT. Each controller is fed by a composite clock (the usual
mux, divider and gate). The muxes inputs are the xtal (default) and the
fclk_div clocks. These parents, along with the divider, should be able to
provide the necessary rates for mmc and nand operation.

The input muxes should also be able to take mpll2, mpll3 and gp0_pll but
these are precious clocks, needed for other usage. It is better if the
mmc does not use these them. For this reason, mpll2, mpll3 and gp0_pll is
not listed among the possible parents.

Subject: mlxsw: spectrum_switchdev: Don't warn about valid situations

Some operations in the bridge driver such as MDB deletion are preformed
in an atomic context and thus deferred to a process context by the
switchdev infrastructure.

Therefore, by the time the operation is performed by the underlying
device driver it's possible the bridge port context is already gone.
This is especially true for removal flows, but theoretically can also be
invoked during addition.

Remove the warnings in such situations and return normally.

Subject: mlxsw: spectrum_switchdev: Release multicast groups during fini

Each multicast group (MID) stores a bitmap of ports to which a packet
should be forwarded to in case an MDB entry associated with the MID is
hit.

Since the initial introduction of IGMP snooping in commit 3a49b4fde2a1
("mlxsw: Adding layer 2 multicast support") the driver didn't correctly
free these multicast groups upon ungraceful situations such as the
removal of the upper bridge device or module removal.

The correct way to fix this is to associate each MID with the bridge
ports member in it and then drop the reference in case the bridge port
is destroyed, but this will result in a lot more code and will be fixed
in net-next.

For now, upon module removal, traverse the MID list and release each
one.

Subject: IB/core: Fix race condition in resolving IP to MAC

Currently while resolving IP address to MAC address single delayed work
is used for resolving multiple such resolve requests. This singled work
is essentially performs two tasks.
(a) any retry needed to resolve and
(b) it executes the callback function for all completed requests

While work is executing callbacks, any new work scheduled on for this
workqueue is lost because workqueue has completed looking at all pending
requests and now looking at callbacks, but work is still under
execution. Any further retry to look at pending requests in
process_req() after executing callbacks would lead to similar race
condition (may be reduce the probably further but doesn't eliminate it).
Retrying to enqueue work that from queue_req() context is not something
rest of the kernel modules have followed.

Therefore fix in this patch utilizes kernel facility to enqueue multiple
work items to a workqueue. This ensures that no such requests
gets lost in synchronization. Request list is still maintained so that
rdma_cancel_addr() can unlink the request and get the completion with
error sooner. Neighbour update event handling continues to be handled in
same way as before.
Additionally process_req() work entry cancels any pending work for a
request that gets completed while processing those requests.

Originally ib_addr was ST workqueue, but it became MT work queue with
patch of [1]. This patch again makes it similar to ST so that
neighbour update events handler work item doesn't race with
other work items.

In one such below trace, (though on 4.5 based kernel) it can be seen
that process_req() never executed the callback, which is likely for an
event that was schedule by queue_req() when previous callback was
getting executed by workqueue.

Subject: IB/uverbs: Fix device cleanup

Uverbs device should be cleaned up only when there is no
potential usage of.

As part of ib_uverbs_remove_one which might be triggered upon reset flow
the device reference count is decreased as expected and leave the final
cleanup to the FDs that were opened.

Current code increases reference count upon opening a new command FD and
decreases it upon closing the file. The event FD is opened internally
and rely on the command FD by taking on it a reference count.

In case that the command FD was closed and just later the event FD we
may ensure that the device resources as of srcu are still alive as they
are still in use.

Fixing the above by moving the reference count decreasing to the place
where the command FD is really freed instead of doing that when it was
just closed.

Subject: ata: ahci_platform: Add shutdown handler

The newly introduced ahci_platform_shutdown() method is called during
system shutdown to disable host controller DMA and interrupts in order
to avoid potentially corrupting or otherwise interfering with a new
kernel being started with kexec.

Subject: ACPI / PM: Prefer suspend-to-idle over S3 on some systems

Modify the ACPI system sleep support setup code to select
suspend-to-idle as the default system sleep state if
(1) the ACPI_FADT_LOW_POWER_S0 flag is set in the FADT and
(2) the Low Power Idle S0 _DSM interface has been discovered and
(3) the default sleep state was not selected from the kernel command
line.

The main motivation for this change is that systems where the (1) and
(2) conditions are met typically ship with OSes that don't exercise
the S3 path in the platform firmware which remains untested and turns
out to be non-functional at least in some cases.

Subject: nfit, libnvdimm, region: export 'position' in mapping info

It is useful to be able to know the position of a DIMM in an
interleave-set. Consider the case where the order of the DIMMs changes
causing a namespace to be invalidated because the interleave-set cookie no
longer matches. If the before and after state of each DIMM position is
known this state debugged by the system owner.

Subject: soc: imx: gpcv2: fix regulator deferred probe

If a regulator requests a deferred probe, the power domain gets
initialized twice. This leads to a list double add (without
list debugging the kernel hangs due to the double add later):

  WARNING: CPU: 0 PID: 19 at lib/list_debug.c:31 __list_add_valid+0xbc/0xc4
  list_add double add: new=c1229754, prev=c12383b4, next=c1229754.

Initialize the power domain after we get the regulator. Also do
not print an error in case the regulator defers probing.

This fixes a problem where the system gets stuck in a loop

The problem happens because:
 - press power button:
   - system emits 0xc0 (power press), event ignored
   - system emits 0xc1 (power release), event processed,
     emited as KEY_POWER
   - set wakeup_mode to true
   - system goes to s2idle
 - press power button
   - system emits 0xc0 (power press), wakeup_mode is true,
     system wakes
   - system emits 0xc1 (power release), event processed,
     emited as KEY_POWER
   - system goes to s2idle again

To avoid this situation, process the presses (which matches what
intel-hid does too).

Subject: iscsi-target: Fix iscsi_np reset hung task during parallel delete

This patch fixes a bug associated with iscsit_reset_np_thread()
that can occur during parallel configfs rmdir of a single iscsi_np
used across multiple iscsi-target instances, that would result in
hung task(s) similar to below where configfs rmdir process context
was blocked indefinately waiting for iscsi_np->np_restart_comp
to finish:

[ 6726.112076] INFO: task dcp_proxy_node_:15550 blocked for more than 120 seconds.

[ 6726.234659]  [<ffffffff8169042e>] system_call_fastpath+0x12/0x71

It would happen because each iscsit_reset_np_thread() sets state
to ISCSI_NP_THREAD_RESET, sends SIGINT, and then blocks waiting
for completion on iscsi_np->np_restart_comp.

However, if iscsi_np was active processing a login request and
more than a single iscsit_reset_np_thread() caller to the same
iscsi_np was blocked on iscsi_np->np_restart_comp, iscsi_np
kthread process context in __iscsi_target_login_thread() would
flush pending signals and only perform a single completion of
np->np_restart_comp before going back to sleep within transport
specific iscsit_transport->iscsi_accept_np code.

To address this bug, add a iscsi_np->np_reset_count and update
__iscsi_target_login_thread() to keep completing np->np_restart_comp
until ->np_reset_count has reached zero.

Subject: net: phy: allow settings table to support more than 32 link modes

Allow the phy settings table to support more than 32 link modes by
switching to the ethtool link mode bit number representation, rather
than storing the mask.  This will allow phylink and other ethtool
code to share the settings table to look up settings.

Subject: net: phy: move phy_lookup_setting() and guts of
 phy_supported_speeds() to phy-core

phy_lookup_setting() provides useful functionality in ethtool code
outside phylib.  Move it to phy-core and allow it to be re-used (eg,
in phylink) rather than duplicated elsewhere.  Note that this supports
the larger linkmode space.

As we move the phy settings table, we also need to move the guts of
phy_supported_speeds() as well.

Add the missing 1000Base-X entry to the phy settings table.  This was
not included because the original code could not cope with more than
32 bits of link mode mask.

Subject: net: phy: provide a hook for link up/link down events

Sometimes, we need to do additional work between the PHY coming up and
marking the carrier present - for example, we may need to wait for the
PHY to MAC link to finish negotiation.  This changes phylib to provide
a notification function pointer which avoids the built-in
netif_carrier_on() and netif_carrier_off() functions.

Standard ->adjust_link functionality is provided by hooking a helper
into the new ->phy_link_change method.

Subject: net: phy: add I2C mdio bus

Add an I2C MDIO bus bridge library, to allow phylib to access PHYs which
are connected to an I2C bus instead of the more conventional MDIO bus.
Such PHYs can be found in SFP adapters and SFF modules.

Since PHYs appear at I2C bus address 0x40..0x5f, and 0x50/0x51 are
reserved for SFP EEPROMs/diagnostics, we must not allow the MDIO bus
to access these I2C addresses.

Subject: phylink: add phylink infrastructure

The link between the ethernet MAC and its PHY has become more complex
as the interface evolves.  This is especially true with serdes links,
where the part of the PHY is effectively integrated into the MAC.

Serdes links can be connected to a variety of devices, including SFF
modules soldered down onto the board with the MAC, a SFP cage with
a hotpluggable SFP module which may contain a PHY or directly modulate
the serdes signals onto optical media with or without a PHY, or even
a classical PHY connection.

Moreover, the negotiation information on serdes links comes in two
varieties - SGMII mode, where the PHY provides its speed/duplex/flow
control information to the MAC, and 1000base-X mode where both ends
exchange their abilities and each resolve the link capabilities.

This means we need a more flexible means to support these arrangements,
particularly with the hotpluggable nature of SFP, where the PHY can
be attached or detached after the network device has been brought up.

Ethtool information can come from multiple sources:
- we may have a PHY operating in either SGMII or 1000base-X mode, in
  which case we take ethtool/mii data directly from the PHY.
- we may have a optical SFP module without a PHY, with the MAC
  operating in 1000base-X mode - the ethtool/mii data needs to come
  from the MAC.
- we may have a copper SFP module with a PHY whic can't be accessed,
  which means we need to take ethtool/mii data from the MAC.

Phylink aims to solve this by providing an intermediary between the
MAC and PHY, providing a safe way for PHYs to be hotplugged, and
allowing a SFP driver to reconfigure the serdes connection.

Phylink also takes over support of fixed link connections, where the
speed/duplex/flow control are fixed, but link status may be controlled
by a GPIO signal.  By avoiding the fixed-phy implementation, phylink
can provide a faster response to link events: fixed-phy has to wait for
phylib to operate its state machine, which can take several seconds.
In comparison, phylink takes milliseconds.

- remove sync status
- rework supported and advertisment handling
- add 1000base-x speed for fixed links
- use functionality exported from phy-core, reworking
  __phylink_ethtool_ksettings_set for it

Subject: sfp: add SFP module support

Add support for SFP hotpluggable modules via sfp-bus and phylink.
This supports both copper and optical SFP modules, which require
different Serdes modes in order to properly negotiate the link.

Optical SFP modules typically require the Serdes link to be talking
1000BaseX mode - this is the gigabit ethernet mode defined by the
802.3 standard.

Copper SFP modules typically integrate a PHY in the module to convert
from Serdes to copper, and the PHY will be configured by the vendor
to either present a 1000BaseX Serdes link (for fixed 1000BaseT) or a
SGMII Serdes link.  However, this is vendor defined, so we instead
detect the PHY, switch the link to SGMII mode, and use traditional
PHY based negotiation.

Subject: liquidio: add missing strings in oct_dev_state_str array

There's supposed to be a one-to-one correspondence between the 18 macros
that #define the OCT_DEV states (in octeon_device.h) and the strings in the
oct_dev_state_str array, but there are only 14 strings in the array.

Add the missing strings (so they become 18 in total), and also revise some
incorrect/outdated text of existing strings.

Subject: net: systemport: Support 64bit statistics

When using Broadcom Systemport device in 32bit Platform, ifconfig can
only report up to 4G tx,rx status, which will be wrapped to 0 when the
number of incoming or outgoing packets exceeds 4G, only taking
around 2 hours in busy network environment (such as streaming).
Therefore, it makes hard for network diagnostic tool to get reliable
statistical result, so the patch is used to add 64bit support for
Broadcom Systemport device in 32bit Platform.

This patch provides 64bit statistics capability on both ethtool and ifconfig.

Subject: netvsc: fix race on sub channel creation

The existing sub channel code did not wait for all the sub-channels
to completely initialize. This could lead to race causing crash
in napi_netif_del() from bad list. The existing code would send
an init message, then wait only for the initial response that
the init message was received. It thought it was waiting for
sub channels but really the init response did the wakeup.

The new code keeps track of the number of open channels and
waits until that many are open.

Other issues here were:
  * host might return less sub-channels than was requested.
  * the new init status is not valid until after init was completed.

Fixes: b3e6b82a0099 ("hv_netvsc: Wait for sub-channels to be processed during probe")

With new transparent VF support, it is possible to get a deadlock
when some of the deferred work is running and the unregister_vf
is trying to cancel the work element. The solution is to use
trylock and reschedule (similar to bonding and team device).

Subject: net: stmmac: Add Adaptrum Anarion GMAC glue layer

Before the GMAC on the Anarion chip can be used, the PHY interface
selection must be configured with the DWMAC block in reset.

This layer covers a block containing only two registers. Although it
is possible to model this as a reset controller and use the "resets"
property of stmmac, it's much more intuitive to include this in the
glue layer instead.

At this time only RGMII is supported, because it is the only mode
which has been validated hardware-wise.

Subject: Bluetooth: bluecard: Always enable LEDs (fix for Anycom CF-300)

Anycom CF-300 (HP C8249A) has both power and activity LEDs.
However the id read in bluecard_open() is 0x73 so the driver does not
enable the LEDs.
Remove the CARD_HAS_PCCARD_ID check to enable LEDs.

Subject: Bluetooth: bluecard: fix LED behavior

Keep power LED on during activity.

LED timer races with power LED disabling in hci_close(), resulting in
power LED left on after closing.
Stop LED timer before disabling power LED.

BTW. On cards without an activity LED, the behavior is a bit weird:
The LED is on after hci_open() but only until the first data transfer.
Then it's off in idle and on during activity.
It could be improved by keeping the LED on in idle and flashing during
activity.

Subject: net/mlx5e: Rearrange netdevice ops structures

Since we are going to allow building the driver without eswitch support,
it would be possible to compile out the sriov netdevice ops struct such
that the basic ops instance will be used for non VF devices too.

Add missing udp tunnel ndos into mlx5e_netdev_ops_basic.

While here, rearrange some ndos in the sriov ops struct and put
vf/eswitch related ndos towards the end of it.

Remove redundant call to unregister vport representor in mlx5e_add error

Hide the representor priv and eswitch internal structures from en_main.c
as preparation step for downstream patches which would allow building
the driver without support for  representors and eswitch.

Subject: net/mlx5: Unify vport manager capability check

Expose MLX5_VPORT_MANAGER macro to check for strict vport manager
E-switch and MPFS (Multi Physical Function Switch) abilities.

VPORT manager must be a PF with an ethernet link and with FW advertised
vport group manager capability

Replace older checks with the new macro and use it where needed in
eswitch.c and mlx5e netdev eswitch related flows.

The same macro will be reused in MPFS separation downstream patch.

Subject: net/mlx5: Separate between E-Switch and MPFS

Multi-Physical Function Switch (MPFs) is required for when multi-PF
configuration is enabled to allow passing user configured unicast MAC
addresses to the requesting PF.

Before this patch eswitch.c used to manage the HW MPFS l2 table,
E-Switch always (regardless of sriov) enabled vport(0) (NIC PF) vport's
contexts update on unicast mac address list changes, to populate the PF's
MPFS L2 table accordingly.

In downstream patch we would like to allow compiling the driver without
E-Switch functionalities, for that we move MPFS l2 table logic out
of eswitch.c into its own file, and provide Kconfig flag (MLX5_MPFS) to
allow compiling out MPFS for those who don't want Multi-PF support.

NIC PF netdevice will now directly update MPFS l2 table via the new MPFS
API. VF netdevice has no access to MPFS L2 table, so E-Switch will remain
responsible of updating its MPFS l2 table on behalf of its VFs.

Due to this change we also don't require enabling vport(0) (PF vport)
unicast mac changes events anymore, for when SRIOV is not enabled.
Which means E-Switch is now activated only on SRIOV activation, and not
required otherwise.

From e80541ecabd57b69726232b89242e28d8123cccc Mon Sep 17 00:00:00 2001
From: Saeed Mahameed <saeedm@mellanox.com>
Date: Mon, 5 Jun 2017 15:17:12 +0300
Subject: net/mlx5: Add CONFIG_MLX5_ESWITCH Kconfig

Allow to selectively build the driver with or without sriov eswitch, VF
representors and TC offloads.

Also remove the need of two ndo ops structures (sriov & basic)
and keep only one unified ndo ops, compile out VF SRIOV ndos when not
needed (MLX5_ESWITCH=n), and for VF netdev calling those ndos will result
in returning -EPERM.

Subject: net/mlx5: Delay events till ib registration ends

When mlx5_ib registers itself to mlx5_core as an interface, it will
call mlx5_add_device which will call mlx5_ib interface add callback,
in case the latter successfully returns, only then mlx5_core will add
it to the interface list and async events will be forwarded to mlx5_ib.
Between mlx5_ib interface add callback and mlx5_core adding the mlx5_ib
interface to its devices list, arriving mlx5_core events can be missed
by the new mlx5_ib registering interface.

In other words:
thread 1: mlx5_ib: mlx5_register_interface(dev)
thread 1: mlx5_core: mlx5_add_device(dev)
thread 1: mlx5_core: ctx = dev->add => (mlx5_ib)->mlx5_ib_add
thread 2: mlx5_core_event: **new event arrives, forward to dev_list
thread 1: mlx5_core: add_ctx_to_dev_list(ctx)
/* previous event was missed by the new interface.*/
It is ok to miss events before dev->add (mlx5_ib)->mlx5_ib_add_device
but not after.

We fix this race by accumulating the events that come between the
ib_register_device (inside mlx5_add_device->(dev->add)) till the adding
to the list completes and fire them to the new registering interface
after that.

Fixes: f1ee87fe55c8 ("net/mlx5: Organize device list API in one place")

Subject: net/mlx5: Increase the maximum flow counters supported

Read new NIC capability field which represnts 16 MSBs of the max flow
counters number supported (max_flow_counter_31_16).

Backward compatibility with older firmware is preserved, the modified
driver reads max_flow_counter_31_16 as 0 from the older firmware and
uses up to 64K counters.

Changed flow counter id from 16 bits to 32 bits. Backward compatibility
with older firmware is preserved as we kept the 16 LSBs of the counter
id in place and added 16 MSBs from reserved field.

Changed the background bulk reading of flow counters to work in chunks
of at most 32K counters, to make sure we don't attempt to allocate very
large buffers.

Subject: drm/i915/gvt: Change the max length of mmio_reg_rw from 4 to 8

When linux guest access mmio with __raw_i915_read64 or __raw_i915_write64,
its length is 8 bytes.

This fix the linux guest in xengt couldn't boot up as it fail in
reading pv_info->magic.

Subject: drm/i915: Fix out-of-bounds array access in bdw_load_gamma_lut

bdw_load_gamma_lut is writing beyond the array to the maximum value.
The intend of the function is to clamp values > 1 to 1, so write
the intended color to the max register.

This fixes the following KASAN warning:

Subject: staging: vboxvideo: remove dead gamma lut code

The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code that was not doing anything
sensible anyway.

Subject: Revert "reset: Add a Gemini reset controller"

This reverts commit 2acb037fc42b8ce5ae59a7d5db3c9b35672e3dd7.

We ended up merging the reset controller into the clock
controller so we can now get rid of this stand-alone
implementation.

Subject: drm/i915/perf: fix flex eu registers programming

We were reserving fewer dwords in the ring than necessary. Indeed
we're always writing all registers once, so discard the actual number
of registers given by the user and just program the whitelisted ones
once.

In order for us to successfully detect the end of a timeslice,
preemption must be disabled. Otherwise, inside the loop we may be
preempted many times without our noticing, and each time our timeslice
will be reset, invalidating need_resched()

Subject: drm/i915: fix backlight invert for non-zero minimum brightness

When we started following the backlight minimum brightness in
6dda730e55f4 ("drm/i915: respect the VBT minimum backlight brightness")
we overlooked the brightness invert quirk. Even if we invert the
brightness, we need to take the min limit into account. We probably
missed this because the invert has only been required on gen4 for proper
operation.

Subject: spi: use of_property_read_bool()

Use a bit more compact of_property_read_bool() calls instead of the
of_find_property() calls -- symmetrically with the of_property_read_u32()
calls already done in of_spi_parse_dt().

Subject: pinctrl: armada-37xx: Fix the pin 23 on south bridge

Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.

Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.

The bug was visible with the merge of the commit 07d065abf93d "arm64:
dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio
regulator used the gpio 23, due to this the whole rgmii group was setup
to gpio which broke the Ethernet support on the Armada 3720 DB
board. Thanks to this patch, the UHS SD cards (which need the vqmmc)
_and_ the Ethernet work again.

Subject: ACPI: Introduce DMA ranges parsing

Some devices have limited addressing capabilities and cannot
reference the whole memory address space while carrying out DMA
operations (eg some devices with bus address bits range smaller than
system bus - which prevents them from using bus addresses that are
otherwise valid for the system).

The ACPI _DMA object allows bus devices to define the DMA window that is
actually addressable by devices that sit upstream the bus, therefore
providing a means to parse and initialize the devices DMA masks and
addressable DMA range size.

By relying on the generic ACPI kernel layer to retrieve and parse
resources, introduce ACPI core code to parse the _DMA object.

Subject: ACPI: Make acpi_dma_configure() DMA regions aware

Current ACPI DMA configuration set-up device DMA capabilities through
kernel defaults that do not take into account platform specific DMA
configurations reported by firmware.

By leveraging the ACPI acpi_dev_get_dma_resources() API, add code
in acpi_dma_configure() to retrieve the DMA regions to correctly
set-up PCI devices DMA parameters.

Rework the ACPI IORT kernel API to make sure they can accommodate
the DMA set-up required by firmware. By making PCI devices DMA set-up
ACPI IORT specific, the kernel is shielded from unwanted regressions
that could be triggered by parsing DMA resources on arches that were
previously ignoring them (ie x86/ia64), leaving kernel behaviour
unchanged on those arches.

Subject: irqchip: brcmstb-l2: Define an irq_pm_shutdown function

The Broadcom STB platforms support S5 and we allow specific hardware
wake-up events to take us out of this state. Because we were not
defining an irq_pm_shutdown() function pointer, we would not be
correctly masking non-wakeup events, which would result in spurious
wake-ups from sources that were not explicitly configured for wake-up.

The fbdev subsystem has a place for physical dimensions (width and height
in mm) that is readable by userspace. Since DRM also knows these
dimensions, pass this information to the fbdev device.

This has to be done in drm_setup_crtcs_fb() instead of drm_setup_crtcs()
because fb_helper->fbdev may be NULL in drm_setup_crtcs().

Subject: fbdev: matrox: hide unused 'hotplug' variable

The variable has become unused in modular configurations
which triggers a harmless warning:

drivers/video/fbdev/matrox/matroxfb_base.c:1583:12: error: 'hotplug' defined but not used [-Werror=unused-variable]

This moves it into an #ifdef section of the file, matching
all its references.

Subject: spi: rockchip: Fix clock handling in remove

We are assuming clocks enabled when calling rockchip_spi_remove, which
is not always true. Those clocks might already been disabled by the
runtime PM at that time.

Call pm_runtime_get_sync before trying to disable clocks to avoid that.

The runtime suspend callback might be called by pm domain framework at

been disabled by rockchip_spi_suspend.

Call pm_runtime_force_suspend/pm_runtime_force_resume when

Subject: spi: fix building SPI_PXA on MMP

When the audio driver selects CONFIG_PXA_SSP on ARCH_MMP as a
loadable module, and the PXA SPI driver is built-in, we get
a link error in the SPI driver:

drivers/spi/spi-pxa2xx.o: In function `pxa2xx_spi_remove':
spi-pxa2xx.c:(.text+0x5f0): undefined reference to `pxa_ssp_free'
drivers/spi/spi-pxa2xx.o: In function `pxa2xx_spi_probe':
spi-pxa2xx.c:(.text+0xeac): undefined reference to `pxa_ssp_request'
spi-pxa2xx.c:(.text+0x1468): undefined reference to `pxa_ssp_free'
spi-pxa2xx.c:(.text+0x15bc): undefined reference to `pxa_ssp_free'

The problem is that the PXA SPI driver only uses 'select SSP'
specifically when building it for PXA, but we can also build it
for PCI, which is meant for Intel x86 SoCs that use the same SPI
block. When the sound driver forces the SSP to be a loadable
module, the IS_ENABLED() check in include/linux/pxa2xx_ssp.h
triggers but the spi driver can't reference the exported symbols.

I had a different approach before, making the PCI case depend
on X86, which fixed the problem by avoiding the MMP case.

This goes a different route, making the driver select PXA_SSP
also on MMP, which has an SSP that none of the boards in mainline
Linux use for SPI. There is no harm in always enabling the build
on MMP (PCI or not PCI), so I do that too, to document that this
hardware is actually available on MMP.

Subject: backlight: gpio_backlight: Convert to use GPIO descriptor

This driver is predominantly used by device tree systems, all
of which can deal with modern GPIO descriptors. The legacy
GPIO API is only used by one SH board so make the GPIO
descriptor the default way to deal with it.

As an intended side effect we do not need to look around in
the device tree for the inversion flag since the GPIO
descriptors will intrinsically deal with this.

Subject: backlight: gpio_backlight: Delete pdata inversion

The option to invert the output of the GPIO (active low) is
not used by the only platform still using platform data to
set up a GPIO backlight (one SH board). Delete the option
as we do not expect to expand the use of board files for
this driver, and GPIO descriptors intrinsically keep track
of any signal inversion.

Subject: mlxsw: spectrum: push cls_flower and cls_matchall setup_tc processing
 into separate functions

Let mlxsw_sp_setup_tc be a splitter for specific setup_tc types and push
out cls_flower and cls_matchall specific codes into separate functions.

Subject: net: sched: push cls related args into cls_common structure

As ndo_setup_tc is generic offload op for whole tc subsystem, does not
really make sense to have cls-specific args. So move them under
cls_common structurure which is embedded in all cls structs.

Subject: net: sched: move prio into cls_common

prio is not cls_flower specific, but it is meaningful for all
classifiers. Seems that only mlxsw cares about the value. Obviously,
cls offload in other drivers is broken.

 mqprio only

Change the return value from -EINVAL to -EOPNOTSUPP. The rest of the
drivers have it like that, so be aligned.

Subject: net: sched: get rid of struct tc_to_netdev

Get rid of struct tc_to_netdev which is now just unnecessary container
and rather pass per-type structures down to drivers directly.
Along with that, consolidate the naming of per-type structure variables
in cls_*.

Subject: asix: Add rx->ax_skb = NULL after usbnet_skb_return()

In asix_rx_fixup_internal() there is a risk that rx->ax_skb gets
reused after passing the Ethernet frame into the network stack via
usbnet_skb_return().

The risks include:

a) asynchronously freeing rx->ax_skb after passing the netdev buffer
   to the NAPI layer which might corrupt the backlog queue.

b) erroneously reusing rx->ax_skb such as calling skb_put_data() multiple
   times which causes writing off the end of the netdev buffer.

Therefore add a defensive rx->ax_skb = NULL after usbnet_skb_return()
so that it is not possible to free rx->ax_skb or to apply
skb_put_data() too many times.

Subject: asix: Ensure asix_rx_fixup_info members are all reset

There is a risk that the members of the structure asix_rx_fixup_info
become unsynchronised leading to the possibility of a malfunction.

For example, rx->split_head was not being set to false after an
error was detected so potentially could cause a malformed 32-bit
Data header word to be formed.

Therefore add function reset_asix_rx_fixup_info() to reset all the
members of asix_rx_fixup_info so that future processing will start
with known initial conditions.

Also, if (skb->len != offset) becomes true then call
reset_asix_rx_fixup_info() so that the processing of the next URB
starts with known initial conditions. Without the call, the check
does nothing which potentially could lead to a malfunction
when the next URB is processed.

In addition, for robustness, call reset_asix_rx_fixup_info() before
every error path's "return 0". This ensures that the next URB is
processed from known initial conditions.

Subject: asix: Fix small memory leak in ax88772_unbind()

When Ethernet frames span mulitple URBs, the netdev buffer memory
pointed to by the asix_rx_fixup_info structure remains allocated
during the time gap between the 2 executions of asix_rx_fixup_internal().

This means that if ax88772_unbind() is called within this time
gap to free the memory of the parent private data structure then
a memory leak of the part filled netdev buffer memory will occur.

Therefore, create a new function asix_rx_fixup_common_free() to
free the memory of the netdev buffer and add a call to
asix_rx_fixup_common_free() from inside ax88772_unbind().

Consequently when an unbind occurs part way through receiving
an Ethernet frame, the netdev buffer memory that is holding part
of the received Ethernet frame will now be freed.

Currently the activity LED is solid on during continuous activity.
Blink the LED during continuous activity to match Windows driver
behavior.

Cards with activity LED:
power LED = solid on when up, off when down
activity LED = blinking during activity, off when idle

Cards without activity LED:
power LED = solid on when up, off when down, blinking during activity
(don't have such a card so I don't know if Windows driver does the same
thing)

Subject: scsi: aacraid: use aac_tmf_callback for reset fib

When sending a reset fib we shouldn't rely on the scsi command,
but rather set the TMF status in the map_info->reset_state variable.
That allows us to send a TMF independent on a scsi command.

aac_hba_send() will return FAILED for any non-SCSI command requests,
failing any TMFs. This patch updates the check to allow TMFs.

Subject: scsi: g_NCR5380: Fix PDMA transfer size

generic_NCR5380_dma_xfer_len() incorrectly uses cmd->transfersize which
causes rescan-scsi-bus and CD-ROM access to hang the system.  Use
cmd->SCp.this_residual instead, like other NCR5380 drivers.

Subject: scsi: g_NCR5380: End PDMA transfer correctly on target disconnection

When an IRQ arrives during PDMA transfer, pread() and pwrite() return
without waiting for the 53C80 registers to be ready and this ends up
messing up the chip state. This was observed with SONY CDU-55S which is
slow enough to disconnect during 4096-byte reads.

IRQ during PDMA is not an error so don't return -1. Instead, store the
remaining byte count for use by NCR5380_dma_residual().

[Poll for the BASR_END_DMA_TRANSFER condition rather than remove the
error message -- F.T.]

Subject: scsi: g_NCR5380: Re-work PDMA loops

The polling loops in pread() and pwrite() can easily become infinite
loops and hang the machine.

Merge the IRQ check into host buffer wait loop and add polling limit.

Also place a limit on polling for 53C80 registers accessibility.

[Use NCR5380_poll_politely2() for register polling. Rely on polling for
gated IRQ rather than polling for phase error, like the algorithm in the
53c400 datasheet. Move DTC436 workarounds into a separate patch.
Factor-out common code as wait_for_53c80_access(). Rework the residual
calculations. -- F.T.]

Subject: scsi: g_NCR5380: Two DTC436 PDMA workarounds

Limit PDMA send to 512 B to avoid data corruption on DTC3181E. The
corruption is always the same: one byte missing at the beginning of a
128 B block. It happens only with slow Quantum LPS 240 drive, not with
faster IBM DORS-32160. It's not clear what causes this. Documentation
for the DTC436 chip has not been made available.

Subject: scsi: megaraid: Replace PCI pool old API

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.

Subject: scsi: mpt3sas: Replace PCI pool old API

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.

This makes the code use a truncating snprintf() instead, which shuts

Subject: scsi: mpt3sas: fix format overflow warning

We print the driver name into one string and then add and ID
and copy it into a second string of the same length, at which
point gcc complains about a possible overflow:

drivers/scsi/mpt3sas/mpt3sas_scsih.c: In function '_scsih_probe':

  sprintf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id);
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Making the first string shorter is sufficient to avoid the
warning here, as we know it can only contain either "mpt2sas"
or "mpt3sas".

Subject: scsi: gdth: increase the procfs event buffer size

We print a 256 byte event string into a buffer that is only 161
bytes long, this is clearly wrong:

drivers/scsi/gdth_proc.c: In function 'gdth_show_info':
drivers/scsi/gdth.c:3660:41: error: '%s' directive writing up to 255 bytes into a region of size between 141 and 150 [-Werror=format-overflow=]
             sprintf(buffer,"Adapter %d: %s\n",
                                         ^~
/git/arm-soc/drivers/scsi/gdth.c:3660:13: note: 'sprintf' output between 13 and 277 bytes into a destination of size 161
             sprintf(buffer,"Adapter %d: %s\n",
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                 dvr->eu.async.ionode,dvr->event_string);
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

gcc calculates that the worst case buffer size would be 277 bytes,
so we can use that.

Subject: scsi: fusion: fix string overflow warning

gcc points out a theorerical string overflow:

drivers/message/fusion/mptbase.c: In function 'mpt_detach':
drivers/message/fusion/mptbase.c:2103:17: error: '%s' directive writing up to 31 bytes into a region of size 28 [-Werror=format-overflow=]
sprintf(pname, MPT_PROCFS_MPTBASEDIR "/%s/summary", ioc->name);
               ^~~~~
drivers/message/fusion/mptbase.c:2103:2: note: 'sprintf' output between 13 and 44 bytes into a destination of size 32

We can simply double the size of the local buffer here to be on the
safe side, and using snprintf() instead of sprintf() protects us
if ioc->name was not terminated properly.

Subject: scsi: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: scsi: remove DRIVER_ATTR() usage

It's better to use the DRIVER_ATTR_RW() and DRIVER_ATTR_RO() macros to
explicitly show that this is a read/write or read/only sysfs file.  So
convert the remaining SCSI drivers that use the old style to use the
newer macros.

Bonus is that this removes some checkpatch.pl warnings :)

This is part of a series to drop DRIVER_ATTR() from the tree entirely.

Subject: scsi: fc: start decoupling fc_block_scsi_eh from scsi_cmnd

Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(),
eh_target_reset_handler(), and eh_host_reset_handler() which do not have
the scope of one single SCSI command.  These callbacks tend to use
fc_block_scsi_eh() requiring scsi_cmnd.  In order to start decoupling
above eh callbacks from scsi_cmnd, introduce a new variant of the
function called fc_block_rport() taking an fc_rport as argument.
Refactor the old fc_block_scsi_eh() to simply delegate to
fc_block_rport().

Subject: hns3: fix unused function warning

Without CONFIG_PCI_IOV, we get a harmless warning about an
unused function:

drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c:2273:13: error: 'hclge_disable_sriov' defined but not used [-Werror=unused-function]

The #ifdefs in this driver are obviously wrong, so this just
removes them and uses an IS_ENABLED() check that does the same
thing correctly in a more readable way.

Subject: s390/qeth: fix L3 next-hop in xmit qeth hdr

On L3, the qeth_hdr struct needs to be filled with the next-hop
IP address.
The current code accesses rtable->rt_gateway without checking that
rtable is a valid address. The accidental access to a lowcore area
results in a random next-hop address in the qeth_hdr.
rtable (or more precisely, skb_dst(skb)) can be NULL in rare cases
(for instance together with AF_PACKET sockets).
This patch adds the missing NULL-ptr checks.

Subject: hysdn: fix to a race condition in put_log_buffer

The synchronization type that was used earlier to guard the loop that
deletes unused log buffers may lead to a situation that prevents any
thread from going through the loop.

The patch deletes previously used synchronization mechanism and moves
the loop under the spin_lock so the similar cases won't be feasible in
the future.

Subject: of_mdio: use of_property_read_u32_array()

The "fixed-link" prop support predated of_property_read_u32_array(), so
basically had to open-code it. Using the modern API saves 24 bytes of the
object code (ARM gcc 4.8.5); the only behavior change would be that the
prop length check is now less strict (however the strict pre-check done
in of_phy_is_fixed_link() is left intact anyway)...

Subject: net: dsa: lan9303: Rename lan9303_xxx_packet_processing()

The lan9303_enable_packet_processing, lan9303_disable_packet_processing
functions operate on port, so the names should reflect that.
And to align with lan9303_disable_processing(), rename:

lan9303_enable_packet_processing -> lan9303_enable_processing_port
lan9303_disable_packet_processing -> lan9303_disable_processing_port

From 1b6dd556c3045ca5fa31cc1e98a4a43afa680e1e Mon Sep 17 00:00:00 2001
From: Arkadi Sharshevsky <arkadis@mellanox.com>
Date: Sun, 6 Aug 2017 16:15:40 +0300
Subject: net: dsa: Remove prepare phase for FDB

The prepare phase for FDB add is unneeded because most of DSA devices
can have failures during bus transactions (SPI, I2C, etc.), thus, the
prepare phase cannot guarantee success of the commit stage.

The support for learning FDB through notification chain, which will be
introduced in the following patches, will provide the ability to notify
back the bridge about successful offload.

Subject: net: dsa: Remove support for vlan dump from DSA's drivers

This is done as a preparation before removing support for vlan dump from
DSA core. The vlans are synced with the bridge and thus there is no
need for special dump operation support.

Subject: net: dsa: Remove support for MDB dump from DSA's drivers

This is done as a preparation before removing support for MDB dump from
DSA core. The MDBs are synced with the bridge and thus there is no
need for special dump operation support.

Subject: net: dsa: Move FDB dump implementation inside DSA

>From all switchdev devices only DSA requires special FDB dump. This is due
to lack of ability for syncing the hardware learned FDBs with the bridge.
Due to this it is removed from switchdev and moved inside DSA.

Subject: qed: Fix a memory allocation failure test in 'qed_mcp_cmd_init()'

We allocate 'p_info->mfw_mb_cur' and 'p_info->mfw_mb_shadow' but we check
'p_info->mfw_mb_addr' instead of 'p_info->mfw_mb_cur'.

'p_info->mfw_mb_addr' is never 0, because it is initiliazed a few lines
above in 'qed_load_mcp_offsets()'.

Update the test and check the result of the 2 'kzalloc()' instead.

Subject: HID: asus: Add T100CHI bluetooth keyboard dock touchpad support

Put the touchpad in native (absolute coordinate mode) and export it to
userspace as a touchpad rather then as a mouse.

Note this requires HID_QUIRK_MULTI_INPUT as the T100CHI keyboard dock
has all functionality on a single HID interface and userspace expects
touchpads to be on a separate input_dev. Without MULTI_INPUT userspace
will ignore the keyboard part of the keyboard/touchpad combo.

Subject: HID: wacom: Do not completely map WACOM_HID_WD_TOUCHRINGSTATUS usage

The WACOM_HID_WD_TOUCHRINGSTATUS usage is a single bit which tells us
whether the touchring is currently in use or not. Because we need to
reset the axis value to 0 when the finger is removed, we call
'wacom_map_usage' to ensure that the required type/code values are
associated with the usage. The 'wacom_map_usage' also sets up the axis
range and resolution, however, which is not desired in this particular
case.

Although xf86-input-wacom doesn't do really do anything with the ring's
range or resolution, the libinput driver (for Wayland environments)
uses these values to provide proper angle indications to userspace.

Subject: mmc: host: omap_hsmmc: Add CMD23 capability to omap_hsmmc driver

omap_hsmmc driver always relied on CMD12 to stop transmission.
However if CMD12 is not issued at the correct timing, the card will
indicate a out of range error. With certain cards in some of the
DRA7 based boards, -EIO error is observed. By Adding CMD23 capability,
the MMC core will send MMC_SET_BLOCK_COUNT command before
MMC_READ_MULTIPLE_BLOCK/MMC_WRITE_MULTIPLE_BLOCK commands.

commit a04e6bae9e6f12 ("mmc: core: check also R1 response for
stop commands") exposed this bug in omap_hsmmc driver.

 for HDMI 2.0 PHY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently HDMI 2.0 PHYs do not have a default configuration function.

As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D
PHYs we can provide the same default configuration function for both
and still let user overwrite this with custom configuration function
if needed.

If, for some reason, the PHY is custom or has a register different
register layout then custom configuration function *must* be provided
in order for the system to work correctly. As we prefer the pdata
provided configuration function over the internal one this change
will not make any impact in custom platforms.

Subject: powerpc/powernv/idle: Disable LOSE_FULL_CONTEXT states when stop-api
 fails

Currently, we use the opal call opal_slw_set_reg() to inform the
Sleep-Winkle Engine (SLW) to restore the contents of some of the
Hypervisor state on wakeup from deep idle states that lose full
hypervisor context (characterized by the flag
OPAL_PM_LOSE_FULL_CONTEXT).

However, the current code has a bug in that if opal_slw_set_reg()
fails, we don't disable the use of these deep states (winkle on
POWER8, stop4 onwards on POWER9).

This patch fixes this bug by ensuring that if programing the
sleep-winkle engine to restore the hypervisor states in
pnv_save_sprs_for_deep_states() fails, then we exclude such states by
clearing the OPAL_PM_LOSE_FULL_CONTEXT flag from
supported_cpuidle_states. As a result POWER8 will be prevented from
using winkle for CPU-Hotplug, and POWER9 will put the offlined CPUs to
the default stop state when available.

Further, we ensure in the initialization of the cpuidle-powernv driver
to only include those states whose flags are present in
supported_cpuidle_states, thereby skipping OPAL_PM_LOSE_FULL_CONTEXT
states when they have been disabled due to stop-api failure.

Fixes: 1e1601b38e6 ("powerpc/powernv/idle: Restore SPRs for deep idle
states via stop API.")

Subject: ath10k: fix memory leak in rx ring buffer allocation

The rx ring buffers are added to a hash table if
firmware support full rx reorder. If the full rx
reorder support flag is not set before allocating
the rx ring buffers, none of the buffers are added
to the hash table.

There is a race condition between rx ring refill and
rx buffer replenish from napi poll. The interrupts are
enabled in hif start, before the rx ring is refilled during init.
We replenish buffers from napi poll due to the interrupts which
get enabled after hif start. Hence before the entire rx ring is
refilled during the init, the napi poll replenishes a few buffers
in steps of 100 buffers per attempt. During this rx ring replenish
from napi poll, the rx reorder flag has not been set due to which
the replenished buffers are not added to the hash table

Set the rx full reorder support flag before we allocate
the rx ring buffer to avoid the memory leak.

Subject: wcn36xx: Introduce mutual exclusion of fw configuration

As the association status changes the driver needs to configure the
hardware. This is done based on information in the "sta" acquired by
ieee80211_find_sta(), which requires the caller to ensure that the "sta"
is valid while its being used; generally by entering an rcu read
section.

But the operations acting on the "sta" has to communicate with the
firmware and may therefor sleep, resulting in the following report:

In order to ensure that the "sta" remains alive (and consistent) for the
duration of bss_info_changed() mutual exclusion has to be ensured with
sta_remove().

This is done by introducing a mutex to cover firmware configuration
changes, which is made to also ensure mutual exclusion between other
operations changing the state or configuration of the firmware. With
this we can drop the rcu read lock.

Subject: spi: qup: Enable chip select support

Enable chip select support for QUP versions later than v1. The
chip select support was broken in QUP version 1. Hence the chip
select support was removed earlier in an earlier commit
(4a8573abe "spi: qup: Remove chip select function"). Since the
chip select support is functional in recent versions of QUP,
re-enabling it for QUP versions later than v1.

Subject: spi: qup: Setup DMA mode correctly

To operate in DMA mode, the buffer should be aligned and
the size of the transfer should be a multiple of block size
(for v1). And the no. of words being transferred should
be programmed in the count registers appropriately.

Subject: spi: qup: Fix transaction done signaling

Wait to signal done until we get all of the interrupts we are expecting
to get for a transaction.  If we don't wait for the input done flag, we
can be in between transactions when the done flag comes in and this can
mess up the next transaction.

While here cleaning up the code which sets controller->xfer = NULL and
restores it in the ISR. This looks to be some debug code which is not
required.

Subject: spi: qup: refactor spi_qup_io_config into two functions

This is in preparation for handling transactions larger than
64K-1 bytes in block mode, which is currently unsupported and
quietly fails.

We need to break these into two functions 1) prep is
called once per spi_message and 2) io_config is called
once per spi-qup bus transaction

This is just refactoring, there should be no functional
change

Subject: spi: qup: call io_config in mode specific function

DMA transactions should only only need to call io_config only once, but
block mode might call it several times to setup several transactions so
it can handle reads/writes larger than the max size per transaction, so
we move the call to the do_ functions.

This is just refactoring, there should be no functional change

Subject: spi: qup: allow block mode to generate multiple transactions

This let's you write more to the SPI bus than 64K-1 which is important
if the block size of a SPI device is >= 64K or some other device wants
to do something larger.

This has the benefit of completely removing spi_message from the spi-qup
transactions

Subject: spi: qup: Ensure done detection

This patch fixes an issue where a SPI transaction has completed, but the
done condition is missed.  This occurs because at the time of interrupt the
MAX_INPUT_DONE_FLAG is not asserted.  However, in the process of reading
blocks of data from the FIFO, the last portion of data comes in.

The opflags read at the beginning of the irq handler no longer matches the
current opflag state.  To get around this condition, the block read
function should update the opflags so that done detection is correct after
the return.

Subject: rsi: buffer full check optimization

We get buffer full event from firmware whenever Tx queue is full
Host should stop writing packets after this and resume after
buffer free event.
Buffer status checking is optimized for once in 4 times if
BUFF_FULL condition is not set, otherwise once for every
packet.

Subject: rsi: buffer available interrupt handling

BUFFER_AVAILABLE interrupt is sent by firmware to indicate
change in buffer status. We should check buffer status while
handling this interrupt. Currently buffer status is checked
only while dequeueing packets. This patch fixes a data
traffic stuck problem observed occasionally.

Subject: mwifiex: replace netif_carrier_on/off by netif_device_attach/dettach

Driver is doing netif_carrier_off during suspend, which will set
the IFF_LOWER_UP flag to 0. As a result certain applications
will think this as a real carrier down and behave accordingly.
This will cause issues like loss of IP address, for example. To
fix this use netif_device_dettach during suspend.

Fixes: 0026b32d723e ('mwifiex: fix Tx timeout issue during suspend test')

Commit 4d7ab36f0c47 ("mwifiex: Do not change bss_type in

keep the same style, in this way. Unique tuple (bss_type, bss_num) will
be able to locate the right priv structure.

Subject: brcmfmac: set wpa_auth to WPA_AUTH_DISABLED in AP/OPEN security mode

When setting wpa_auth to WPA_AUTH_NONE(1) in AP mode with WEP security,
firmware will set privacy bit and add WPA OUI in VENDOR IE in beacon and
probe response. The security type in softAP beacons confuse the
supplicant in client side, and the user client will see [WPA-?] in
supplicant scan result. So we set WPA_AUTH_DISABLED in softAP mode with
OPEN security.

Subject: brcmfmac: fix wrong num_different_channels when mchan feature enabled

When the device/firmware supports multi-channel, it can have P2P
connection and regular connection with AP simultaneous. In this case,
the num_different_channels in wiphy info was not correct when firmware
supports multi-channel (The iw wiphy# info showed "#channels <= 1" in
interface combinations). It caused association failed and error message
"CTRL-EVENT-FREQ-CONFLICT error" in wpa_supplicant when P2P GO interface
was running at the same time.
The root cause is that the num_different_channels was always overridden
to 1 in brcmf_setup_ifmodes even multi-channel was enabled.
We correct the logic by moving num_different_channels setting forward.

Subject: rt2x00: Fix MMIC Countermeasures

Set RX_FLAG_DECRYPTED in case of MMIC failure so that
ieee80211_rx_h_decrypt() doesnt drop the frame before getting to
ieee80211_rx_h_michael_mic_verify().

Subject: drm/omap: Rework the rotation-on-crtc hack

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

v4: Review from Laurent
- Move struct omap_crtc_state into omap_crtc.c
- Clean up comments.
- Don't forget to copy the shadowed state over on duplicate.

v5: Don't forget to update the reset handler (Maarten).
v6: Update omap_crtc_state shadow values in omap_crtc_atomic_check (Maarten).
v7:
- Fix get_property to return 0 and set value in *val (Maarten).
- Update comment in set_property for changes in v6 (Maarten).

Subject: drm: Don't update property values for atomic drivers

Atomic drivers only use the property value store for immutable (i.e.
can't be set by userspace, but the kernel can still adjust it)
properties. The only tricky part is the removal of the update in
drm_atomic_helper_update_legacy_modeset_state().

This was added in

commit 8c10342cb48f3140d9abeadcfd2fa6625d447282 (tag: topic/drm-misc-2015-07-28)

    drm/atomic: Update legacy DPMS state during modesets, v3.

by copying it from the i915 code, where it was originally added in

commit 68d3472047a572936551f8ff0b6f4016c5a1fdef
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Thu Sep 6 22:08:35 2012 +0200

    drm/i915: update dpms property in set_mode

for the legacy modeset code. The reason we needed this hack was that
i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of
the newer-ish drm_drv_uses_atomic_modeset(), which avoids such
troubles. With the correct feature checks this isn't needed anymore at
all.

Also make sure that drivers don't accidentally get this wrong by
making the exported version of drm_object_property_get_value() only
work for legacy drivers. Only gma500 uses it anyway.

v2: Fixup the uses_atomic_modeset() checks (Maarten)

Subject: drm: Handle properties in the core for atomic drivers

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_plane_set_property.

Subject: drm: Nuke drm_atomic_helper_connector_set_property

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_connector_set_property.

The only special case is nouveau which used one function for both
pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

Subject: thermal: intel_pch_thermal: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

Subject: perf: xgene: Remove unnecessary managed resources cleanup

Managed resources in the driver should be automatically cleaned up on
driver detach. It's unnecessary to manually free/unmmap these resources.
One of the manual cleanup causes static checkers to complain.
The bug is reported by Dan Carpenter <dan.carpenter@oracle.com> in [1]

[1] https://www.spinics.net/lists/arm-kernel/msg593012.html

This patch gets rid of all the unnecessary manual cleanup and properly
unregister all the registered PMU devices by the driver on driver detach.

Subject: drm/etnaviv: select CMA and DMA_CMA if available

While this is no build dependency, etnaviv will only work correctly on most
systems if CMA and DMA_CMA are enabled. Select both options if available to
avoid users ending up with a non-working GPU due to a lacking kernel config.

Subject: drm/etnaviv: switch to drm_*{get,put} helpers

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() adn should not be
used by new code. So convert all users of compatibility functions to use
the new APIs.

Subject: drm/i915: Perform an invalidate prior to executing golden renderstate

As we may have just bound the renderstate into the GGTT for execution, we
need to ensure that the GTT TLB are also flushed.

On snb-gt2, this would cause a random GPU hang at the start of a new
context (e.g. boot) and on snb-gt1, it was causing the renderstate batch
to take ~10s. It was the GPU hang that revealed the truth, as the CS
gleefully executed beyond the end of the golden renderstate batch, a good
indicator for a GTT TLB miss.

Subject: md: always clear ->safemode when md_check_recovery gets the mddev
 lock.

If ->safemode == 1, md_check_recovery() will try to get the mddev lock
and perform various other checks.
If mddev->in_sync is zero, it will call set_in_sync, and clear
->safemode.  However if mddev->in_sync is not zero, ->safemode will not
be cleared.

When md_check_recovery() drops the mddev lock, the thread is woken
up again.  Normally it would just check if there was anything else to
do, find nothing, and go to sleep.  However as ->safemode was not
cleared, it will take the mddev lock again, then wake itself up
when unlocking.

This results in an infinite loop, repeatedly calling
md_check_recovery(), which RCU or the soft-lockup detector
will eventually complain about.

Prior to commit 4ad23a976413 ("MD: use per-cpu counter for
writes_pending"), safemode would only be set to one when the
writes_pending counter reached zero, and would be cleared again
when writes_pending is incremented.  Since that patch, safemode
is set more freely, but is not reliably cleared.

So in md_check_recovery() clear ->safemode before checking ->in_sync.

Subject: md: fix test in md_write_start()

md_write_start() needs to clear the in_sync flag is it is set, or if
there might be a race with set_in_sync() such that the later will
set it very soon.  In the later case it is sufficient to take the
spinlock to synchronize with set_in_sync(), and then set the flag
if needed.

The current test is incorrect.
It should be:
  if "flag is set" or "race is possible"

"flag is set" is trivially "mddev->in_sync".
"race is possible" should be tested by "mddev->sync_checkers".

If sync_checkers is 0, then there can be no race.  set_in_sync() will
wait in percpu_ref_switch_to_atomic_sync() for an RCU grace period,
and as md_write_start() holds the rcu_read_lock(), set_in_sync() will
be sure ot see the update to writes_pending.

If sync_checkers is > 0, there could be race.  If md_write_start()
happened entirely between
		if (!mddev->in_sync &&
		    percpu_ref_is_zero(&mddev->writes_pending)) {
and
			mddev->in_sync = 1;
in set_in_sync(), then it would not see that is_sync had been set,
and set_in_sync() would not see that writes_pending had been
incremented.

This bug means that in_sync is sometimes not set when it should be.
Consequently there is a small chance that the array will be marked as
"clean" when in fact it is inconsistent.

Subject: md/r5cache: fix io_unit handling in r5l_log_endio()

In r5l_log_endio(), once log->io_list_lock is released, the io unit
may be accessed (or even freed) by other threads. Current code
doesn't handle the io_unit properly, which leads to potential race
conditions.

This patch solves this race condition by:

1. Add a pending_stripe count flush_payload. Multiple flush_payloads
   are counted as only one pending_stripe. Flag has_flush_payload is
   added to show whether the io unit has flush_payload;
2. In r5l_log_endio(), check flags has_null_flush and
   has_flush_payload with log->io_list_lock held. After the lock
   is released, this IO unit is only accessed when we know the
   pending_stripe counter cannot be zeroed by other threads.

Subject: ACPI/IORT: Handle PCI aliases properly for IOMMUs

When a PCI device has DMA quirks, we need to ensure that an upstream
IOMMU knows about all possible aliases, since the presence of a DMA
quirk does not preclude the device still also emitting transactions
(e.g. MSIs) on its 'real' RID. Similarly, the rules for bridge aliasing
are relatively complex, and some bridges may only take ownership of
transactions under particular transient circumstances, leading again to
multiple RIDs potentially being seen at the IOMMU for the given device.

Take all this into account in iort_iommu_configure() by mapping every
RID produced by the alias walk, not just whichever one comes out last.
Since adding any more internal PTR_ERR() juggling would have confused me
no end, a bit of refactoring happens in the process - we know where to
find the ops if everything succeeded, so we're free to just pass regular
error codes around up until then.

Subject: PM / wakeup: Set power.can_wakeup if wakeup_sysfs_add() fails

Currently, an error from wakeup_sysfs_add() in
device_set_wakeup_capable() causes the device's power.can_wakeup
flag to remain unset even though the device technically is capable
of signaling wakeup.

If wakeup_sysfs_add() fails user space may not be able to enable
the device to wake up the system from sleep states, but at least
for some devices that does not matter.

For this reason, set or clear power.can_wakeup upfront and if
wakeup_sysfs_add() returns an error, print a message to the log.

Subject: clk: rockchip: modify rk3128 clk driver to also support rk3126

rk3128 and rk3126 have some gate registers describe differences.
So need to make some distinctions.
The RK3126 and RK3128 Same clock description we move it to
the common clock branches.
And the different clks description use the own clock branches.

Subject: clk: fractional-divider: allow overriding of approximation

Fractional dividers may have special requirements concerning numerator
and denominator selection that differ from just getting the best
approximation.

For example on Rockchip socs the denominator must be at least 20 times
larger than the numerator to generate precise clock frequencies.

Therefore add the ability to provide custom approximation functions.

Subject: clk: rockchip: add special approximation to fix up fractional clk's
 jitter

>From Rockchips fractional divider description:
  3.1.9  Fractional divider usage
  To get specific frequency, clocks of I2S, SPDIF, UARTcan be generated by
  fractional divider. Generally you must set that denominator is 20 times
  larger than numerator to generate precise clock frequency. So the
  fractional divider applies only to generate low frequency clock like
  I2S, UART.

Therefore add a special approximation function that handles this
special requirement.

This patch fixes system hang/crash while firmware dump is attempted with
Block MQ enabled in qla2xxx driver. Fix is to remove check in fw dump
template entries for existing request and response queues so that full
buffer size is calculated during template size calculation.

Following stack trace is seen during firmware dump capture process

Subject: scsi: st: fix blk_get_queue usage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If blk_queue_get() in st_probe fails, disk->queue must not be set to
SDp->request_queue, as that would result in put_disk() dropping a not
taken reference.

Thus, disk->queue should be set only after a successful blk_queue_get().

Subject: scsi: ipr: Fix scsi-mq lockdep issue

Fixes the following lockdep warning that can occur when scsi-mq is
enabled with ipr due to ipr calling scsi_unblock_requests from irq
context. The fix is to move the call to scsi_unblock_requests to ipr's
existing workqueue.

Rather than continue adding CPU-specific event maps, instead look up by

if either the event isn't described by PMUv3, or it is described but
the PMCEID registers say that it is unsupported by the current CPU.

Subject: random: fix warning message on ia64 and parisc

Fix the warning message on the parisc and IA64 architectures to show the
correct function name of the caller by using %pS instead of %pF. The
message is printed with the value of _RET_IP_ which calls
__builtin_return_address(0) and as such returns the IP address caller
instead of pointer to a function descriptor of the caller.

The effect of this patch is visible on the parisc and ia64 architectures
only since those are the ones which use function descriptors while on
all others %pS and %pF will behave the same.

Subject: wil6210: fix interface-up check

While wil_open is executed, any call to netif_running
would return a success. In case there are failures
within wil_open, should not treat the device as if it
is already opened in relevant functions (like FW recovery
and runtime suspend check).

Fix that by checking the device up flag instead.

OPA address handle atttibutes that have 32 bit LIDs would have to
be converted to IB address handle attribute with the LID field
programmed in the GID before copying to user space.

Subject: IB/CM: Set appropriate slid and dlid when handling CM request

If extended LIDs are being used, a connection request contains
OPA GIDs in them. Extract the lids from the OPA gids and populate
slid/dlid fields in the path records that are created when handling
a connection request.

Subject: mlx5: convert to generic pci_alloc_irq_vectors

Now that we have a generic code to allocate an array
of irq vectors and even correctly spread their affinity,
correctly handle cpu hotplug events and more, were much
better off using it.

Subject: mlx5e: don't assume anything on the irq affinity mappings of the
 device

mlx5e currently assumes that irq affinity is really spread first
irq vectors across device home node cpus, with the new generic affinity
mappings this is no longer the case, hence mlxe should not rely on
this anymore.

Subject: mlx5: move affinity hints assignments to generic code

generic api takes care of spreading affinity similar to
what mlx5 open coded (and even handles better asymmetric
configurations). Ask the generic API to spread affinity
for us, and feed him pre_vectors that do not participate
in affinity settings (which is an improvement to what we
had before).

The affinity assignments should match what mlx5 tried to
do earlier but now we do not set affinity to async, cmd
and pages dedicated vectors.

Also, remove mlx5e_get_cpu and introduce mlx5e_get_node
(used for allocation purposes) and mlx5_get_vector_affinity
(for indirection table construction) as they provide the needed
information. Luckily, we have generic helpers to get cpumask
and node given a irq vector. mlx5_get_vector_affinity will
be used by mlx5_ib in a subsequent patch.

Use the generic block layer affinity mapping helper. Also,
limit nr_hw_queues to the rdma device number of irq vectors
as we don't really need more.

of_find_node_with_property() drops the reference to the 'from' node,

to the node causing all sorts of fun problems, and this nice splat.

Subject: drm/i915/cnl: Removing missing DDI_E bits from CNL.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DDI_E is not supported on CNL-U and CNL-Y

When adding the initial support we noticed DDI_E wasn't supported
and removed it on v4 and v5 of that patch.
However for some reason I missed or put back these 2 chunks.

Time to clean it up to avoid later confusion.

Subject: drm/vc4: Fix double destroy of the BO cache on teardown.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It's also destroyed from the top level vc4_drv.c initialization, which
is where the cache was actually initialized from.

This used to just involve duplicate del_timer() and cancel_work_sync()
being called, but it started causing kmalloc issues once we
double-freed the new BO label array.

drm_*_reference() and drm_*_unreference() functions are just

From: Eric Anholt <eric@anholt.net>
Date: Tue, 25 Jul 2017 09:27:33 -0700
Subject: drm/vc4: Add exec flags to allow forcing a specific X/Y tile walk
 order.

This is useful to allow GL to provide defined results for overlapping
glBlitFramebuffer, which X11 in turn uses to accelerate uncomposited
window movement without first blitting to a temporary.  x11perf
-copywinwin100 goes from 1850/sec to 4850/sec.

v2: Default to the same behavior as before when the flags aren't
    passed. (suggested by Boris)

Subject: drm/exynos: forbid creating framebuffers from too small GEM buffers

Add a check if the framebuffer described by the provided drm_mode_fb_cmd2
structure fits into provided GEM buffers. Without this check it is
possible to create a framebuffer object from a small buffer and set it to
the hardware, what results in displaying system memory outside the

Subject: soc: qcom: mdt_loader: Use request_firmware_into_buf()

By switching to the request_firmware_into_buf() we load the segment data
straight into the preallocated buffers, reducing the need for allocating
scratch buffers for these. In particular the modem firmware consists of
multiple segments in the range 5-15MB, making this worth while.

Subject: igb: Fix error of RX network flow classification

After add an ethertype filter, if user change the adapter speed several
times, the error "ethtool -N: etype filters are all used" is reported by
igb driver.

In older patch, function igb_nfc_filter_exit() and igb_nfc_filter_restore()
is not paried. igb_nfc_filter_restore() exist in igb_up(), but function
igb_nfc_filter_exit() is exist in __igb_close(). In the process of speed
changing, only igb_nfc_filter_restore() is called, it will take a position
of ethertype bitmap.

Reproduce steps:
Step 1: Add a etype filter by ethtool
$ethtool -N eth0 flow-type ether proto 0x88F8 action 1
Step 2: Change the adapter speed to 100M/full duplex
$ethtool -s eth0 speed 100 duplex full
Step 3: Change the adapter speed to 1000M/full duplex
ethtool -s eth0 speed 1000 duplex full
Repeat step2 and step3, then dmesg the system log, you can find the error
message, add new ethtype filter is also failed.

This fixing is move igb_nfc_filter_exit() from __igb_close() to igb_down()
to make igb_nfc_filter_restore()/igb_nfc_filter_exit() is paired.

Subject: igb: protect TX timestamping from API misuse

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the igb
driver still allowed TX packets to request HW timestamping. In this
situation, the _IGB_PTP_TX_IN_PROGRESS flag was set and would never
clear. This prevented any future HW timestamping requests to succeed.

Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

Subject: igb: Remove incorrect "unexpected SYS WRAP" log message

TSAUXC.DisableSystime is never set, so SYSTIM runs into a SYS WRAP
every 1100 secs on 80580/i350/i354 (40 bit SYSTIM) and every 35000
secs on 80576 (45 bit SYSTIM).

This wrap event sets the TSICR.SysWrap bit unconditionally.

However, checking TSIM at interrupt time shows that this event does not
actually cause the interrupt.  Rather, it's just bycatch while the
actual interrupt is caused by, for instance, TSICR.TXTS.

The conclusion is that the SYS WRAP is actually expected, so the
"unexpected SYS WRAP" message is entirely bogus and just helps to
confuse users.  Drop it.

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.

Subject: bpf/verifier: rework value tracking

Unifies adjusted and unadjusted register value types (e.g. FRAME_POINTER is
 now just a PTR_TO_STACK with zero offset).
Tracks value alignment by means of tracking known & unknown bits.  This
 also replaces the 'reg->imm' (leading zero bits) calculations for (what
 were) UNKNOWN_VALUEs.
If pointer leaks are allowed, and adjust_ptr_min_max_vals returns -EACCES,
 treat the pointer as an unknown scalar and try again, because we might be
 able to conclude something about the result (e.g. pointer & 0x40 is either
 0 or 0x40).
Verifier hooks in the netronome/nfp driver were changed to match the new
 data structures.

Subject: igb: do not drop PF mailbox lock after read of VF message

When the PF receives a mailbox message from the VF, it grabs the mailbox
lock, reads the VF message from the mailbox, ACKs the message and drops
the lock.

While the PF is performing the action for the VF message, nothing
prevents another VF message from being posted to the mailbox.  The
current code handles this condition by just dropping any new VF messages
without processing them.  This results in a mailbox timeout in the VM
for posted messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.

Given the right sequence of VF messages and mailbox timeouts, this
condition can go on ad infinitum.

Modify the PF mailbox read method to take an 'unlock' argument that
optionally leaves the mailbox locked by the PF after reading the VF
message.  This ensures another VF message is not posted to the mailbox
until after the PF has completed processing the VF message and written
its reply.

Subject: igbvf: add lock around mailbox ops

The PF driver assumes the VF will not send another mailbox message until
the PF has written its reply to the previous message.  If the VF does,
that message will be silently dropped by the PF before it writes its
reply to the mailbox.  This results in a VF mailbox timeout for posted
messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.

Add a lock around the VF mailbox ops to prevent the VF from sending
another message while the PF is still processing the previous one.

Subject: net/mlx4_en: don't set CHECKSUM_COMPLETE on SCTP packets

if the NIC fails to validate the checksum on TCP/UDP, and validation of IP
checksum is successful, the driver subtracts the pseudo-header checksum
from the value obtained by the hardware and sets CHECKSUM_COMPLETE. Don't
do that if protocol is IPPROTO_SCTP, otherwise CRC32c validation fails.

V2: don't test MLX4_CQE_STATUS_IPV6 if MLX4_CQE_STATUS_IPV4 is set

Subject: net: dsa: mediatek: add adjust link support for user ports

Manually adjust the port settings of user ports once PHY polling has
completed. This patch extends the adjust_link callback to configure the
per port PMCR register, applying the proper values polled from the PHY.
Without this patch flow control was not always getting setup properly.

Subject: netvsc: make sure and unregister datapath

Go back to switching datapath directly in the notifier callback.
Otherwise datapath might not get switched on unregister.

No need for calling the NOTIFY_PEERS notifier since that is only for
a gratitious ARP/ND packet; but that is not required with Hyper-V
because both VF and synthetic NIC have the same MAC address.

Subject: cxgb4: Clear On FLASH config file after a FW upgrade

Because Firmware and the Firmware Configuration File need to be
in sync; clear out any On-FLASH Firmware Configuration File when new
Firmware is loaded.  This will avoid difficult to diagnose and fix
problems with a mis-matched Firmware Configuration File which prevents the
adapter from being initialized.

Subject: ppp: fix xmit recursion detection on ppp channels

Commit e5dadc65f9e0 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.

This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.

Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

Fixes: e5dadc65f9e0 ("ppp: Fix false xmit recursion detect with two ppp devices")

Change post-decrement compare to pre-decrement to avoid an
unsigned integer wrap-around on timeout. This leads to the following

qmi_wwan_disconnect is called twice when disconnecting devices with
separate control and data interfaces.  The first invocation will set
the interface data to NULL for both interfaces to flag that the
disconnect has been handled.  But the matching NULL check was left
out when qmi_wwan_disconnect was added, resulting in this oops:

Subject: iwlwifi: mvm: start mac queues when deferred tx frames are purged

In AP mode, if a station is removed just as it is adding a new stream,
the queue in question will remain stopped and no more TX will happen
in this queue, leading to connection failures and other problems.

This is because under DQA, when tx is deferred because a queue needs
to be allocated, the mac queue for that TID is stopped until the new
stream is added.  If at this point the station that this stream
belongs to is removed, all the deferred tx frames are purged, but the
mac queue is not restarted. As a result, all following tx on this
queue will not be transmitted.

Fix this by starting the relevant mac queues when the deferred tx
frames are purged.

Subject: iwlwifi: mvm: don't WARN when a legit race happens in A-MPDU

When we start an Rx A-MPDU session, we first get the AddBA
request, then we send an ADD_STA command to the firmware
that will reply with a BAID which is a hardware resource
that tracks the BA session.
This BAID will appear on each and every frame that we get
from the firwmare until the A-MPDU session is torn down.
In the Rx path, we look at this BAID to manage the
reordering buffer.

This flow is inherently racy since the hardware will start
to put the BAID in the frames it receives even if the
firmware hasn't sent the response to the ADD_STA command.
This basically means that the driver can get frames with
a valid BAID that it doesn't know yet.
When that happens, the driver used to WARN.
Fix this by simply not WARN in this case. When the driver
will know abou the BAID, it will initialise the relevant
states and the next frame with a valid BAID will refresh
them.

of_irq_get() may return 0 as well as negative error number on failure,
while the driver only checks for the negative values. The driver would then
call request_irq(0, ...) in tegra_adma_alloc_chan_resources() and never get
valid channel interrupt.

Check for 'tdc->irq <= 0' instead and return -ENXIO from the driver's probe
iff of_irq_get() returned 0.

Subject: iwlwifi: mvm: use firmware LED command where applicable

On devices starting from 8000 series, the host can no longer toggle
the LED through the CSR_LED_REG register, but must do it via the
firmware instead. Add support for this. Note that this means that
the LED cannot be turned on while the firmware is off, so using an
arbitrary LED trigger may not work as expected.

Fixes: 503ab8c56ca0 ("iwlwifi: Add 8000 HW family support")

Subject: iwlwifi: mvm: add const to thermal_cooling_device_ops structure

Declare thermal_cooling_device_ops structure as const as it is only passed
as an argument to the function thermal_cooling_device_register and this
argument is of type const. So, declare the structure as const.

Subject: iwlwifi: mvm: add debugfs to force CT-kill

CT-kill is a thermal-based "RF-kill", which disables the NIC
completely if the temperature gets too high, in order to avoid damage.

Add a debugfs entry to simulate high temperatures, in order to test
CT-kill flows in the driver without having to physically heat the
device up.

Subject: iwlwifi: fix a few instances of misaligned kerneldoc parameters

There are a few places where we don't have a space between the * and
the @ in the parameter description.  Also, in one case, the @ had
trailing space before the parameter name.

Subject: iwlwifi: mvm: send delba upon rx ba session timeout

When an RX block-ack session times out, the firmware, which offloads
RX reordering but not the BA session negotiation, stops the session
but doesn't send a DELBA.  This causes the the session to remain
active in the remote device, so no more BA sessions will be
established, causing a severe throughput degradation due to the lack
of aggregation.

Use the new ieee80211_rx_ba_timer_expired API when the ba session timer
expires, since this will tear down the ba session and also send a delba.

The previous API used is intended for drivers that offload the
addba/delba negotiation, but not the rx reordering, while our driver
does the opposite.

This patch depends on "mac80211: add api to start ba session timer
expired flow".

platform_get_irq() returns an error code, but the renesas_usb3 driver

prevents -EPROBE_DEFER from being propagated properly.

Also, notice that platform_get_irq() no longer returns 0 on error:

Print error message and propagate the return value of platform_get_irq
on failure.

Subject: usb: dwc3: keystone: Add PM_RUNTIME Support to DWC3 Keystone USB
 driver

For 66AK2Gx there is a requirement to use PM Runtime to properly manage
clocks and the power domains. Therefore, add PM runtime support. Remove
legacy clock api's calls since other users of this driver worked without
these clock apis calls.

Subject: usb: gadget: udc: renesas_usb3: add debugfs to set the b-device mode

This patch adds debugfs to set the "b-device" mode for using a board
which is not connected to the ID pin (e.g. CN11 on Salvator-X).
If we want to use peripheral mode on such a board, we have to disable
VBUS output first. So, this patch can set such a mode as the following:

 # mount -t debugfs none /sys/kernel/debug
 # modprobe renesas_usb3
 # modprobe g_mass_storage file=/dev/shm/test.bin
 # echo 1 > /sys/kernel/debug/ee020000.usb/b_device

This patch adds support for R-Car H3 ES2.0. Since this SoC revision
doesn't need workaround for vbus detection and number of ramif is
increased. So, this driver uses soc_device_match() to detect it.

Subject: crypto: ixp4xx - Fix error handling path in 'aead_perform()'

In commit 0f987e25cb8a, the source processing has been moved in front of
the destination processing, but the error handling path has not been
modified accordingly.
Free resources in the correct order to avoid some leaks.

Subject: crypto: ccp - avoid uninitialized variable warning

The added support for version 5 CCPs introduced a false-positive
warning in the RSA implementation:

drivers/crypto/ccp/ccp-ops.c: In function 'ccp_run_rsa_cmd':
drivers/crypto/ccp/ccp-ops.c:1856:3: error: 'sb_count' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This changes the code in a way that should make it easier for
the compiler to track the state of the sb_count variable, and
avoid the warning.

Subject: crypto: ccp - select CONFIG_CRYPTO_RSA

Without the base RSA code, we run into a link error:

ERROR: "rsa_parse_pub_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined!
ERROR: "rsa_parse_priv_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined!

Like the other drivers implementing RSA in hardware, this
can be avoided by always enabling the base support when we build
CCP.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Most of the dentry members from structure caam_drv_private
are never used at all, so it is safe to remove them.

Since debugfs_remove_recursive() is called, we don't need the
file entries.

Subject: RDMA/core: Add wait/retry version of ibnl_unicast

Add a wait/retry version of ibnl_unicast, ibnl_unicast_wait,
and modify ibnl_unicast to not wait/retry.  This eliminates
the undesirable wait for future users of ibnl_unicast.

Change Portmapper calls originating from kernel to user-space
to use ibnl_unicast_wait and take advantage of the wait/retry
logic in netlink_unicast.

Subject: s390/vmcp: fix uaccess check and avoid undefined behavior

The vmcp device driver should return -EFAULT if get_user() fails, due
to an invalid user space address. In addition the buffer size value
from user space is passed unchecked to get_order(). The return value
of get_order(0) undefined.

Therefore explicitly test for zero before calling get_order() and also
return -EFAULT if get_user() fails.

Subject: s390/cpcmd,vmcp: avoid GFP_DMA allocations

According to the CP Programming Services manual Diagnose Code 8
"Virtual Console Function" can be used in all addressing modes. Also
the input and output buffers do not have a limitation which specifies
they need to be below the 2GB line.

This is true at least since z/VM 5.4.

Therefore remove the sam31/64 instructions and allow for simple
GFP_KERNEL allocations. This makes it easier to allocate a 1MB page
if the user requested such a large return buffer.

Subject: s390/vmcp: make use of contiguous memory allocator

If memory is fragmented it is unlikely that large order memory
allocations succeed. This has been an issue with the vmcp device
driver since a long time, since it requires large physical contiguous
memory ares for large responses.

To hopefully resolve this issue make use of the contiguous memory
allocator (cma). This patch adds a vmcp specific vmcp cma area with a
default size of 4MB. The size can be changed either via the
VMCP_CMA_SIZE config option at compile time or with the "vmcp_cma"
kernel parameter (e.g. "vmcp_cma=16m").

For any vmcp response buffers larger than 16k memory from the cma area
will be allocated. If such an allocation fails, there is a fallback to
the buddy allocator.

Subject: s390/vmcp: return -ENOTTY for unknown ioctl commands

Return -ENOTTY for unknown ioctl commands instead of
-ENOIOCTLCMD. This isn't that much of difference, since common code
will translate -ENOIOCTLCMD to -ENOTTY anyway, but this way it seems

Subject: s390/vmcp: simplify vmcp_ioctl()

vmcp_ioctl() has many different return statements and duplicates a lot
of mutex_unlock() calls. Simplify this so that only one return
statement and one mutex_unlock() call is left.

Subject: s390/scm: use common completion path

Since commit caf7df122721 ("block: remove the errors field from struct request")
rq->errors can't be (mis)used by block device drivers to store the error
condition for usage during async completion. Because of that I simply used
async completion only for the non-error paths.

This patch places the error within the private data of struct request and
uses async completion for all paths again.

Subject: iio: adc: stm32: add optional st,min-sample-time-nsecs

STM32 ADC allows each channel to be sampled with a different sampling time,
by setting SMPR registers. Basically, value depends on local electrical
properties. Selecting correct value for sampling time highly depends on
analog source impedance. There is a manual that may help in this process:
'How to get the best ADC accuracy in STM32...'

This patch allows to configure minimum sampling time via device tree,
either for:
- all channels at once:
  st,min-sample-time-nsecs = <10000>;

- independently for each channel (must match "st,adc-channels" list):
  st,adc-channels = <0 1>;
  st,min-sample-time-nsecs = <5000 10000>;

Subject: iio: adc: ti-ads7950: Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
SPI device registered via OF will always match a legacy SPI device ID and
that the MODALIAS reported will always be of the form spi:<device>.

There is an ACPI method to enumerate such devices via specific ACPI ID
and use of compatible strings. It will not work for the drivers which
have no OF match ID table present.

Besides this could change in the future so the correct approach is to
have an OF device ID table if the devices are registered via OF.

Subject: drm: Shift wrap bug in create_in_format_blob()

"plane->format_count" can go up to 64.  (It's capped in
drm_universal_plane_init().)  So we should be using ULL type instead of
int here to prevent shift wrapping.

Subject: clk: samsung: Add CLK_SET_RATE_PARENT to some AUDSS CLK CON clocks

This allows clk rate propagation up to the clock tree so EPLL
can be reprogrammed indirectly when setting rate of the Audio
Subsystem clocks.
The advantage is that sound machine driver can operate only
on the leaf clocks rather than explicitly re-configuring
the root clock (EPLL).

This adds parameters for vaddr and clip to tinydrm_xrgb8888_to_gray8() to
make it more generic.

dma_buf_{begin,end}_cpu_access() are moved out to the repaper driver.

Return type is change to void to simplify error handling by callers.

Subject: power: supply: Fix power_supply_am_i_supplied to return -ENODEV when
 apropriate

Commit 2848e039c562 ("power: supply: Make power_supply_am_i_supplied return
-ENODEV if there are no suppliers") was supposed to make
power_supply_am_i_supplied() return -ENODEV when there are no supplies
which supply the supply passed to it.

But instead it will only return -ENODEV when there are no supplies at
all as data->count++; is incremented on every call of the iterator, rather
then only when __power_supply_is_supplied_by returns true. This commit
fixes this.

Fixes: 2848e039c562 ("power: supply: Make power_supply_am_i_supplied ...")

Subject: spi: spi-sh: fix error return code in spi_sh_probe()

platform_get_irq() returns an error code, but the spi-sh driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

Subject: spi: spi-ep93xx: use 32-bit read/write for all registers

All the EP93xx SSP registers are 32-bit. Since most of the upper bits
are unused, this driver tries to be tricky and uses 8 or 16-bit I/O to
access the registers. This really just adds a bit of confusion.

Simplify the I/O by using 32-bit read/write's for all of the registers.

This driver currently enables the hardware at the start of every
message and disabled it when the message is complete. Make it a
bit smarter by adding the prepare_transfer_hardware() and
unprepare_transfer_hardware() callbacks so that the core can
enable/disable the hardware based on spi message queue.

pointer is passed around instead of the private data ep93xx_spi pointer.

This allows removing the 'pdev' member of the private data and will
help with some later cleanup.

Subject: drm/i915/psr: Preserve SRD_CTL bit 29 on PSR init

Bit 29 of SRD_CTL needs to have its value preserved according to the
B-Spec, so right before we write out the register we go ahead and read
the register and preserve the value of that bit before we write out
the configured register value.

Subject: iwlwifi: mvm: add station before allocating a queue

One of the queue config params is the associated station id.
Hence the FW must know about the station prior to the queue allocation.
In a000 devices, allocating a queue without a valid station
results with assert 0x2B00.
In FW restart flow the queues are allocated before
adding the station so first add the station.

Subject: iwlwifi: pcie: don't init a Tx queue with an SSN > size of the queue

The TVQM tells us the initial write pointer for a queue,
but that write pointer is in WiFi sequence number unit
and not in TFD index unit. Which means that the write
pointer in the TVQM's response can be bigger than the
Tx queue ring size.

Fix that by modulo'ing the write pointer from the TVQM
with the Tx queue size.

Subject: iwlwifi: remove references to unsupported HW

There are still some references to 3945 and 4965 HW, which were never
supported in iwlwifi.  These references were inherited from a previous
project and are irrelevant here.  Additionally, remove some irrelevant
references to 5100 HW.  Remove all these.

Subject: iwlwifi: pcie: free the TSO page when a Tx queue is unmapped on A000
 devices

When we unmap a non-empty Tx queue, we need to free the
pages that we allocated for the headers in TSO flows.
This code existed for the 9000 device family, but somehow
it got left out when the new Tx path for the A000 devices
was written.

From b0f847e16c1ea6ead5680cf58cade70918363315 Mon Sep 17 00:00:00 2001
From: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

Subject: HID: hid-sensor-hub: Force logical minimum to 1 for power and report
 state

In the reference HID sensor hub firmware all Named array enums were
0-based. There is no description of the default base of enums in HID
sensor hub specification as logical minimum should have set this base
value.

Every sensor hub implemented enum as 1-based, without explicitly setting
logical minimum to 1, because of the implementation by one of the major
OS vendor. In Linux we used logical minimum to decide the enum base.

Some sensor hub FWs already changed logical minimum from 0 to 1. We hoped
that every other vendor will follow. But that didn't happen and we had to
fix the report header for every sensor hub to change logical minimum to 1
by using .report_fixup() callback. So for every new sensor hub we had to
modify source code by adding this quirk based on the vendor and device id.
This is becoming a maintenance burden.

This patch hardcodes the logical minimum of power and report state
attributes to 1. In this way we can remove the existing quirks and also
we don't have to add more quirks.

Subject: iommu: Finish making iommu_group support mandatory

Now that all the drivers properly implementing the IOMMU API support
groups (I'm ignoring the etnaviv GPU MMUs which seemingly only do just
enough to convince the ARM DMA mapping ops), we can remove the FIXME
workarounds from the core code. In the process, it also seems logical to
make the .device_group callback non-optional for drivers calling
iommu_group_get_for_dev() - the current callers all implement it anyway,
and it doesn't make sense for any future callers not to either.

Subject: cpufreq: Return 0 from ->fast_switch() on errors

CPUFREQ_ENTRY_INVALID is a special symbol which is used to specify that
an entry in the cpufreq table is invalid. But using it outside of the
scope of the cpufreq table looks a bit incorrect.

We can represent an invalid frequency by writing it as 0 instead if we
need. Note that it is already done that way for the return value of the
->get() callback.

Lets do the same for ->fast_switch() and not use CPUFREQ_ENTRY_INVALID
outside of the scope of cpufreq table.

Also update the comment over cpufreq_driver_fast_switch() to clearly
mention what this returns.

None of the drivers return CPUFREQ_ENTRY_INVALID as of now from
->fast_switch() callback and so we don't need to update any of those.

Subject: cpufreq: mediatek: add support of cpufreq to MT7622 SoC

MT7622 is a 64-bit ARMv8 based dual-core SoC (2 * Cortex-A53) with a
single cluster. The hardware is also compatible with the current driver,
so add MT7622 as one of the compatible string list.

Subject: ACPI / LPSS: Don't abort ACPI scan on missing mem resource
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The keyboard and touchpad on MacBook's from 2015 onwards are connected
via an SPI bus. On MacBook8's (2015) the ACPI device for the SPI master
for this bus has _CID "INT33C1", and hence the acpi-lpss handler here is
triggered for it. However, the DSDT lists no memory resources for this
device, resulting in an error being returned by the attach callback and
therefore the SPI master device being ignored. This prevents us from
being able to register the keyboard and touchpad driver.

Furthermore, the controller (a Wildcat Point-LP controller) does not
appear to need the functionality provided by the apci-lpss handler.
Therefore we now just skip the handler if no memory resources are found
and let the ACPI scan complete successfully for this device.

All of this is not an issue on later MacBook(Pro)'s because their ACPI
SPI devices don't have any _CID and therefore no attempt is made to attach
this handler.

Returning an error was introduced in commit d3e13ff3c1aa - this restores
the original behaviour.

Subject: drm/i915/gvt: Optimize ring siwtch 2x faster by removing unnecessary
 POSTING_READ

There are lots of POSTING_READ alongside each mmio write Op. While
actually this is not necessary. It just bring too much latency since
PCIe read Op is very slow which is of non-posted transaction.

For PCIe device, the mem transaction for strong ordering rules are:
  o PCIe mmio write sequence is FIFO. Posted request cannot
    pass previous posted request.
  o PCIe mmio read will not go ahead of previous write.

Intel graphics doesn't support RO, so we can apply above rules. In
our case, we only need one POSTING_READ at last. This can remove
half of mmio read Op and then the average ring switch performance
is nearly doubled.
         Before       After
cycles  ~970000      ~550000

Subject: drm/i915/gvt: Optimize ring siwtch 2x faster again by light weight
 mmio access wrapper

The I915_READ/WRITE is not only a mmio read/write, it also contains
debug checking and Forcewake domain lookup. This is too heavy for
GVT ring switch case which access batch of mmio registers on ring
switch. We can handle Forcewake manually and use the raw
i915_read/write instead. The benefit from this is 2x faster mmio
switch performance.

Subject: drm/i915/gvt: Factor out scan and shadow from workload dispatch

To perform the workload scan and shadow in ELSP writing stage for
performance consideration, the workload scan and shadow stuffs
should be factored out from dispatch_workload().

v2:Put context pin before i915_add_request;
   Refine the comments;
   Rename some APIs;

v3:workload->status should set only when error happens.
v4:i915_add_request is must to have after i915_gem_request_alloc.

Subject: drm/i915/gvt: Audit and shadow workload during ELSP writing

Let the workload audit and shadow ahead of vGPU scheduling, that
will eliminate GPU idle time and improve performance for multi-VM.

The performance of Heaven running simultaneously in 3VMs has
improved 20% after this patch.

v2:Remove condition current->vgpu==vgpu when shadow during ELSP
writing.

Remove duplicated MMIO entries in the tracked MMIO list. -EEXIST
is returned if duplicated MMIO entries are found when new MMIO
entry is added.

Subject: drm/i915/gvt: Add carefully checking in GTT walker paths

When debugging the gtt code, found the intel_vgpu_gma_to_gpa() can
translate any given GMA though the GMA is not valid. This because
the GTT ops suppress the possible errors, which may result in an
invalid PT entry is retrieved by upper caller.

This patch changed the prototype of pte ops to propagate status to
callers. Then we make sure the GTT walker stop as early as when
a error is detected to prevent undefined behavior.

Subject: drm/i915/gvt: Refine the intel_vgpu_reset_gtt reset function

When doing the VGPU reset, we don't need to do the gtt/ppgtt reset.
This will make the GVT to do the ppgtt shadow every time for
a workload and caused really bad performance after a VGPU reset.
This patch will make sure ppgtt clean only happen at device module
level reset to fix this.

Subject: drm/i915/gvt: Add shadow context descriptor updating

The current context logic only updates the descriptor of context when
it's being pinned to graphics memory space. But this cannot satisfy the
requirement of shadow context. The addressing mode of the pinned shadow
context descriptor may be changed according to the guest addressing mode.
And this won't be updated, as the already pinned shadow context has no
chance to update its descriptor. And this will lead to GPU hang issue,
as shadow context is used with wrong descriptor. This patch fixes this
issue by letting the pinned shadow context descriptor update its
addressing mode on demand.

This patch fixes GPU HANG issue which happends after changing the
grub parameter i915.enable_ppgtt form 0x01 to 0x03 or vice versa and
then rebooting the guest.

Subject: target: Fix node_acl demo-mode + uncached dynamic shutdown regression

This patch fixes a generate_node_acls = 1 + cache_dynamic_acls = 0
regression, that was introduced by

  commit 01d4d673558985d9a118e1e05026633c3e2ade9b
  Author: Nicholas Bellinger <nab@linux-iscsi.org>
  Date:   Wed Dec 7 12:55:54 2016 -0800

which originally had the proper list_del_init() usage, but was
dropped during list review as it was thought unnecessary by HCH.

However, list_del_init() usage is required during the special
generate_node_acls = 1 + cache_dynamic_acls = 0 case when
transport_free_session() does a list_del(&se_nacl->acl_list),
followed by target_complete_nacl() doing the same thing.

This was manifesting as a general protection fault as reported

To address this, go ahead and use proper list_del_list() for all
cases of se_nacl->acl_list deletion.

Subject: sunvdc: prevent sunvdc panic when mpgroup disk added to guest domain

Using mpgroup to define multiple paths for a virtual disk causes multiple
virtual-device-port ports to be created for that virtual device.
Each virtual-device-port port then gets a vdisk created for it by the Linux
sunvdc driver. As mpgroup is not supported by the Linux sunvdc driver it
cannot handle multiple ports for a single vdisk, leading to a kernel panic
at startup.

This fix prevents more than one vdisk per virtual-device-port being created
until full virtual disk multipathing (mpgroup) support is implemented.

Subject: ibmvnic: Correct 'unused variable' warning in build.

Commit a248878d7a1d ("ibmvnic: Check for transport event on driver resume")
removed the loop to kick irqs on driver resume but didn't remove the now
unused loop variable 'i'.

Subject: net: systemport: Fix software statistics for SYSTEMPORT Lite

With SYSTEMPORT Lite we have holes in our statistics layout that make us
skip over the hardware MIB counters, bcm_sysport_get_stats() was not
taking that into account resulting in reporting 0 for all SW-maintained
statistics, fix this by skipping accordingly.

Subject: geneve: maximum value of VNI cannot be used

Geneve's Virtual Network Identifier (VNI) is 24 bit long, so the range
of values for it would be from 0 to 16777215 (2^24 -1).  However, one
cannot create a geneve device with VNI set to 16777215. This patch fixes
this issue.

Subject: net-next: mediatek: bring up QDMA RX ring 0

This patch is in preparation for adding HW flow and QoS offloading. For
those features to work, the driver needs to bring up the first QDMA RX
ring. This ring is used by the PPE offloading HW.

Subject: nvme: strip trailing 0-bytes in wwid_show

Some broken controllers (such as earlier Linux targets) pad model or
serial fields with 0-bytes rather than spaces. The NVMe spec disallows
0 bytes in "ASCII" fields.  Thus strip trailing 0-bytes, too. Also make
sure that we get no underflow for pathological input.

Subject: libertas_tf: constify usb_device_id

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.

Subject: clk: samsung: exynos542x: Enable clock rate propagation up to the
 EPLL

The CLK_SET_RATE_PARENT flag is added to clocks between the EPLL
and the audio subsystem clock controller so that the EPLL's output
frequency can be set indirectly with clk_set_rate() on a leaf clock.
That should be safe as EPLL is normally only used to generate clock
for the audio subsystem.
With this change we can avoid passing the EPLL clock to the ASoC
machine driver.

Subject: nvmet_fc: add defer_req callback for deferment of cmd buffer return

At queue creation, the transport allocates a local job struct
(struct nvmet_fc_fcp_iod) for each possible element of the queue.
When a new CMD is received from the wire, a jobs struct is allocated
from the queue and then used for the duration of the command.
The job struct contains buffer space for the wire command iu. Thus,
upon allocation of the job struct, the cmd iu buffer is copied to
the job struct and the LLDD may immediately free/reuse the CMD IU
buffer passed in the call.

However, in some circumstances, due to the packetized nature of FC
and the api of the FC LLDD which may issue a hw command to send the
wire response, but the LLDD may not get the hw completion for the
command and upcall the nvmet_fc layer before a new command may be
asynchronously received on the wire. In other words, its possible
for the initiator to get the response from the wire, thus believe a
command slot free, and send a new command iu. The new command iu
may be received by the LLDD and passed to the transport before the
LLDD had serviced the hw completion and made the teardown calls for
the original job struct. As such, there is no available job struct
available for the new io. E.g. it appears like the host sent more
queue elements than the queue size. It didn't based on it's
understanding.

Rather than treat this as a hard connection failure queue the new
request until the job struct does free up. As the buffer isn't
copied as there's no job struct, a special return value must be
returned to the LLDD to signify to hold off on recycling the cmd
iu buffer.  And later, when a job struct is allocated and the
buffer copied, a new LLDD callback is introduced to notify the
LLDD and allow it to recycle it's command iu buffer.

Subject: HID: usbkbd: constify usb_device_id and fix space before '[' error.

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.

Fix checkpatch.pl error:
ERROR: space prohibited before open square bracket '['.

Subject: lpfc: support nvmet_fc defer_rcv callback

Currently, calls to nvmet_fc_rcv_fcp_req() always copied the
FC-NVME cmd iu to a temporary buffer before returning, allowing
the driver to immediately repost the buffer to the hardware.

To address timing conditions on queue element structures vs async
command reception, the nvmet_fc transport occasionally may need to
hold on to the command iu buffer for a short period. In these cases,
the nvmet_fc_rcv_fcp_req() will return a special return code
(-EOVERFLOW). In these cases, the LLDD must delay until the new
defer_rcv lldd callback is called before recycling the buffer back
to the hw.

This patch adds support for the new nvmet_fc transport defer_rcv
callback and recognition of the new error code when passing commands
to the transport.

Subject: nvme-pci: fix CMB sysfs file removal in reset path

Currently we create the sysfs entry even if we fail mapping
it. In that case, the unmapping will not remove the sysfs created
file. There is no good reason to create a sysfs entry for a non
working CMB and show his characteristics.

Subject: RDMA/netlink: Remove netlink clients infrastructure

RDMA netlink has a complicated infrastructure for dynamically
registering and de-registering netlink clients to the NETLINK_RDMA
group. The complicated portion of this code is not widely used because
2 of the 3 current clients are statically compiled together with
netlink.c. The infrastructure, therefore, is deemed overkill.

Refactor the code to eliminate the dynamically added clients. Now all
clients are pre-registered in a client array at compile time, and at run
time they merely check-in with the infrastructure to pass their callback
table for inclusion in the pre-sized client array.

This also allows for future cleanups and removal of unneeded code in the
iwcm* netlink handler.

Owner field is not needed to be set because netlink is part of ib_core
which will be unloaded last after all other modules are unloaded.

Subject: RDMA/netlink: Avoid double pass for RDMA netlink messages

The standard netlink_rcv_skb function skips messages without
NLM_F_REQUEST flag in it, while SA netlink client issues them.

In commit bc10ed7d3d19 ("IB/core: Add rdma netlink helper functions")
the local function was introduced to allow such messages.

This led to double pass for every incoming message.

In this patch, we unify that local implementation and netlink_rcv_skb
functions, so there will be no need for double pass anymore.

As a outcome, this combined function gained more strict check
for NLM_F_REQUEST flag and it is now allowed for SA pathquery
client only.

Subject: RDMA/netlink: Add flag to consolidate common handling

Add ability to provide flags to control RDMA netlink callbacks
and convert addr.c and sa_query.c to be first users of such
infrastructure. It allows to move their CAP_NET_ADMIN checks
into netlink core.

Subject: RDMA/netlink: Rename netlink callback struct

The RDMA netlink client infrastructure was removed and made obsolete.
The old infrastructure defined struct ibnl_client_cbs. Now that all
uses of this have been updated to the new infrastructure, rename the
struct to be compliant with the current stack naming standards:
struct rdma_nl_cbs.

Subject: RDMA/core: Add iterator over ib_devices

The coming nldev needs to iterate over all IB devices in the system
and in order to not expose the ib_devices list outside the devices.c,
it is necessary to provide function iterator.

Current version is written explicitly for nldev callback to avoid
over-engineering at this stage, but it can be easily extended for
other types.

Subject: RDMA/core: Add and expose static device index

This patch adds static device index in similar fashion to
already available in netdev world (struct net->ifindex).

In downstream patches, the RDMA nelink will use this idx-to-ib_device
conversion, so as part of this commit, we are exposing the translation
function to be visible for IB/core users.

Subject: RDMA/netlink: Add and implement doit netlink callback

The .doit callback is used by netlink core to differentiate
between get and set operations. Common convention is to use
that call for command operations like (SET, ADD, e.t.c.) and/or
access without NLF_M_DUMP flag.

This commit adds proper declaration and implementation
to RDMA netlink.

RDMA_NL_LS protocol is actually does not dump anything,
but sets data and it should be handled by doit callback.

This patch actually converts RDMA_NL_LS to doit callback, while
preserving IWCM and RDMA_CM flows through netlink_dump_start().

Subject: RDMA/netlink: Add netlink device definitions to UAPI

Introduce new defines to rdma_netlink.h, so the RDMA configuration tool
will be able to communicate with RDMA subsystem by using the shared defines.

The addition of new client (NLDEV) revealed the fact that we exposed by
mistake the RDMA_NL_I40IW define which is not backed by any RDMA netlink
by now and it won't be exposed in the future too. So this patch reuses
the value and deletes the old defines.

The NLDEV operates with objects. The struct ib_device has two straightforward
objects: device itself and ports of that device.

This brings us to propose the following commands to work on those objects:
 * RDMA_NLDEV_CMD_{GET,SET,NEW,DEL} - works on ib_device itself
 * RDMA_NLDEV_CMD_PORT_{GET,SET,NEW,DEL} - works on ports of specific ib_device

Those commands receive/return the device index (RDMA_NLDEV_ATTR_DEV_INDEX)
and port index (RDMA_NLDEV_ATTR_PORT_INDEX). For device object accesses,
the RDMA_NLDEV_ATTR_PORT_INDEX will return the maximum number of ports
for specific ib_device and for port access the actual port index.

The port index starts from 1 to follow RDMA/core internal semantics and
the sysfs exposed knobs.

Subject: RDMA/netlink: Expose device and port capability masks

The port capability mask is exposed to user space via sysfs interface,
while device capabilities are available for verbs only.

This patch provides those capabilities through netlink interface.

Subject: RDMA: Simplify get firmware interface

There is a need to forward FW version to user space
application through RDMA netlink. In order to make it safe, there
is need to declare nla_policy and limit the size of FW string.

The new define IB_FW_VERSION_NAME_MAX will limit the size of
FW version string. That define was chosen to be equal to
ETHTOOL_FWVERS_LEN, because many drivers anyway are limited
by that value indirectly.

The introduction of this define allows us to remove the string size
from get_fw_str function signature.

Subject: locking/lockdep: Rework FS_RECLAIM annotation

A while ago someone, and I cannot find the email just now, asked if we
could not implement the RECLAIM_FS inversion stuff with a 'fake' lock
like we use for other things like workqueues etc. I think this should
be possible which allows reducing the 'irq' states and will reduce the
amount of __bfs() lookups we do.

Removing the 1 IRQ state results in 4 less __bfs() walks per
dependency, improving lockdep performance. And by moving this
annotation out of the lockdep code it becomes easier for the mm people
to extend.

Subject: drm/i915: Supply the engine-id for our mock_engine()

In the original selftest, we didn't care what the engine->id was, just
that it could uniquely identify it. Later though, we started tracking
the mock engines in the fixed size arrays around the drm_i915_private and
so we now require their indices to be correct. This becomes an issue when
using the standalone harness which runs all available tests at module load,
and so we quickly assign an out-of-bounds index to an engine as we
reallocate the mock GEM device between tests. It doesn't show up in
igt/drv_selftest as that runs each subtest individually.

Subject: clocksource/drivers/arm_arch_timer: Fix mem frame loop initialization

The loop to find the best memory frame in arch_timer_mem_acpi_init()
initializes the loop counter with itself ('i = i'), which is suspicious
in the first place and pointed out by clang. The loop condition is
'i < timer_count' and a prior for loop exits when 'i' reaches
'timer_count', therefore the second loop is never executed.

Initialize the loop counter with 0 to iterate over all timers, which
supposedly was the intention before the typo monster attacked.

Subject: spi: qup: hide warning for uninitialized variable

The added conditionals in this function apparently confused
gcc to the point that it no longer sees the code is safe and
instead shows a false-positive warning:

drivers/spi/spi-qup.c: In function 'spi_qup_transfer_one':
drivers/spi/spi-qup.c:507:28: error: 'tx_nents' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/spi/spi-qup.c:464:17: note: 'tx_nents' was declared here

drivers/spi/spi-qup.c:464:7: note: 'rx_nents' was declared here

This moves the initialization to a place that makes it obvious
to the compiler.

Subject: x86/hyper-v: Make hv_do_hypercall() inline

We have only three call sites for hv_do_hypercall() and we're going to
change HVCALL_SIGNAL_EVENT to doing fast hypercall so we can inline this
function for optimization.

Hyper-V top level functional specification states that r9-r11 registers
and flags may be clobbered by the hypervisor during hypercall and with
inlining this is somewhat important, add the clobbers.

Subject: hyper-v: Use fast hypercall for HVCALL_SIGNAL_EVENT

We need to pass only 8 bytes of input for HvSignalEvent which makes it a
perfect fit for fast hypercall. hv_input_signal_event_buffer is not needed
any more and hv_input_signal_event is converted to union for convenience.

Subject: hyper-v: Globalize vp_index

To support implementing remote TLB flushing on Hyper-V with a hypercall
we need to make vp_index available outside of vmbus module. Rename and
globalize.

Subject: spi: qup: fix 64-bit build warning

On 64-bit systems, pointers are wider than 'int' variables,
so we get a warning about a cast between them:

drivers/spi/spi-qup.c:1060:23: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

This changes the code to use the correct uintptr_t cast.

Subject: irqchip/gic-v3-its: Allow GIC ITS number more than MAX_NUMNODES

When enabling ITS NUMA support on D05, I got the boot log:

[    0.000000] SRAT: PXM 0 -> ITS 0 -> Node 0
[    0.000000] SRAT: PXM 0 -> ITS 1 -> Node 0
[    0.000000] SRAT: PXM 0 -> ITS 2 -> Node 0
[    0.000000] SRAT: PXM 1 -> ITS 3 -> Node 1
[    0.000000] SRAT: ITS affinity exceeding max count[4]

This is wrong on D05 as we have 8 ITSs with 4 NUMA nodes.

So dynamically alloc the memory needed instead of using
its_srat_maps[MAX_NUMNODES], which count the number of
ITS entry(ies) in SRAT and alloc its_srat_maps as needed,
then build the mapping of numa node to ITS ID. Of course,
its_srat_maps will be freed after ITS probing because
we don't need that after boot.

After doing this, I got what I wanted:

[    0.000000] SRAT: PXM 0 -> ITS 0 -> Node 0

Subject: irqchip/gic-v3-its-platform-msi: Fix msi-parent parsing loop

While parsing the msi-parent property to chase up the IRQ domain
a given device belongs to, the index into the msi-parent tuple should
be incremented to ensure all properties entries are taken into account.

Current code missed the index update so the parsing loop does not work
in case multiple msi-parent phandles are present and may turn into
an infinite loop in of_pmsi_get_dev_id() if phandle at index 0 does
not correspond to the domain we are actually looking-up.

Fix the code by updating the phandle index at each iteration in
of_pmsi_get_dev_id().

Subject: drm/i915: Implement .get_format_info() hook for CCS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SKL+ display engine can scan out certain kinds of compressed surfaces
produced by the render engine. This involved telling the display engine
the location of the color control surfae (CCS) which describes which
parts of the main surface are compressed and which are not. The location
of CCS is provided by userspace as just another plane with its own offset.

By providing our own format information for the CCS formats, we should
be able to make framebuffer_check() do the right thing for the CCS
surface as well.

Note that we'll return the same format info for both Y and Yf tiled
format as that's what happens with the non-CCS Y vs. Yf as well. If
desired, we could potentially return a unique pointer for each
pixel_format+tiling+ccs combination, in which case we immediately be
able to tell if any of that stuff changed by just comparing the
pointers. But that does sound a bit wasteful space wise.

v2: Drop the 'dev' argument from the hook
v3: Include the description of the CCS surface layout
v4: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
v5: Re-drop 'dev', fix commit message, add missing drm_fourcc.h
    description of CCS layout. (daniels)

Subject: drm/i915: Add render decompression support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SKL+ display engine can scan out certain kinds of compressed surfaces
produced by the render engine. This involved telling the display engine
the location of the color control surfae (CCS) which describes
which parts of the main surface are compressed and which are not. The
location of CCS is provided by userspace as just another plane with its
own offset.

Add the required stuff to validate the user provided AUX plane metadata
and convert the user provided linear offset into something the hardware
can consume.

Due to hardware limitations we require that the main surface and
the AUX surface (CCS) be part of the same bo. The hardware also
makes life hard by not allowing you to provide separate x/y offsets
for the main and AUX surfaces (excpet with NV12), so finding suitable
offsets for both requires a bit of work. Assuming we still want keep
playing tricks with the offsets. I've just gone with a dumb "search
backward for suitable offsets" approach, which is far from optimal,
but it works.

Also not all planes will be capable of scanning out compressed surfaces,
and eg. 90/270 degree rotation is not supported in combination with
decompression either.

This patch may contain work from at least the following people:
* Vandana Kannan <vandana.kannan@intel.com>
* Daniel Vetter <daniel@ffwll.ch>
* Ben Widawsky <ben@bwidawsk.net>

v2: Deal with display workarounds 0390, 0531, 1125 (Paulo)
v3: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
    Put the AUX register defines to the correct place
    Fix up the slightly bogus rotation check
v4: Use I915_WRITE_FW() due to plane update locking changes
    s/return -EINVAL/goto err/ in intel_framebuffer_init()
    Eliminate a bunch hardcoded numbers in CCS code

v5: (By Ben)

From 714244e280de0e4ec00ff18b641f48be3936d920 Mon Sep 17 00:00:00 2001

Subject: drm/i915: Add format modifiers for Intel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This was based on a patch originally by Kristian. It has been modified
pretty heavily to use the new callbacks from the previous patch.

v2:
  - Add LINEAR and Yf modifiers to list (Ville)
  - Combine i8xx and i965 into one list of formats (Ville)
  - Allow 1010102 formats for Y/Yf tiled (Ville)

v3:
  - Handle cursor formats (Ville)
  - Put handling for LINEAR in the mod_support functions (Ville)

v4:
  - List each modifier explicitly in supported modifiers (Ville)
  - Handle the CURSOR plane (Ville)

v5:
  - Split out cursor and sprite handling (Ville)

v6:
  - Actually use the sprite funcs (Emil)
  - Use unreachable (Emil)

v7:
  - Only allow Intel modifiers and LINEAR (Ben)

v8
  - Fix spite assert introduced in v6 (Daniel)

v9
  - Change vendor check logic to avoid magic 56 (Emil)
  - Reorder skl_mod_support (Ville)
  - make intel_plane_funcs static, could be done as of v5 (Ville)
  - rename local variable intel_format_modifiers to modifiers (Ville)
    - actually use sprite modifiers
  - split out modifier/formats by platform (Ville)

v10:
  - Undo vendor check from v9

v11:
  - Squash CCS advertisement into this patch (daniels)
  - Don't advertise CCS on higher sprite planes (daniels)

v12:
  - Don't advertise Y-tiled or CCS on any sprite planes, since we don't
    allocate enough DDB space for it to work. (daniels)

Subject: ACPI/IORT: Fix build regression without IOMMU

A recent change reintroduced a bug that had previously been
fixed by commit d49f2dedf33b ("ACPI/IORT: Fix CONFIG_IOMMU_API
dependency"):

drivers/acpi/arm64/iort.c: In function 'iort_iommu_configure':
drivers/acpi/arm64/iort.c:829:26: error: 'struct iommu_fwspec' has no member named 'ops'

Replace a direct reference to iommu_fwspec->ops with a helper function
call to fix the issue.

Subject: nvme: fix nvme reset command timeout handling

We need to return an error if a timeout occurs on any NVMe command during
initialization. Without this, the nvme reset work will be stuck. A timeout
will have a negative error code, meaning we need to stop initializing
the controller. All postitive returns mean the controller is still usable.

Subject: x86/hyper-v: Use hypercall for remote TLB flush

Hyper-V host can suggest us to use hypercall for doing remote TLB flush,
this is supposed to work faster than IPIs.

Implementation details: to do HvFlushVirtualAddress{Space,List} hypercalls
we need to put the input somewhere in memory and we don't really want to
have memory allocation on each call so we pre-allocate per cpu memory areas
on boot.

pv_ops patching is happening very early so we need to separate
hyperv_setup_mmu_ops() and hyper_alloc_mmu().

It is possible and easy to implement local TLB flushing too and there is
even a hint for that. However, I don't see a room for optimization on the
host side as both hypercall and native tlb flush will result in vmexit. The
hint is also not set on modern Hyper-V versions.

platform_get_irq() returns an error code, but the ehci-omap driver

Also, notice that platform_get_irq() no longer returns 0 on error:

Subject: usb: mtu3: add a vbus debugfs interface

Provides a new vbus debugfs interface used to turn on/off vbus
regulator, it also can be used to get/put reference count of
vbus, due to sometimes we need keep it alive when manually switch
mtu3 to device mode.

Subject: usb:xhci:Add quirk for Certain failing HP keyboard on reset after
 resume

Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume

On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.

In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.

As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

Subject: USB: Check for dropped connection before switching to full speed

Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure.  This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.

The logic for doing this is careful to check that the device is still
connected.  But this check is inadequate if the device disconnects and
reconnects before the check is done.  The symptom is that a device
works, but much more slowly than it is capable of operating.

The situation was made worse recently by commit 22547c4cc4fe ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.

This patch makes the check more robust.  If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.

The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.

Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the Genesys Logic hub instead.

Subject: vfio/type1: Cope with hardware MSI reserved regions

For ARM-based systems with a GICv3 ITS to provide interrupt isolation,
but hardware limitations which are worked around by having MSIs bypass
SMMU translation (e.g. HiSilicon Hip06/Hip07), VFIO neglects to check
for the IRQ_DOMAIN_FLAG_MSI_REMAP capability, (and thus erroneously
demands unsafe_interrupts) if a software-managed MSI region is absent.

Fix this by always checking for isolation capability at both the IRQ
domain and IOMMU domain levels, rather than predicating that on whether
MSIs require an IOMMU mapping (which was always slightly tenuous logic).

Subject: vfio/type1: Give hardware MSI regions precedence

If the IOMMU driver advertises 'real' reserved regions for MSIs, but
still includes the software-managed region as well, we are currently
blind to the former and will configure the IOMMU domain to map MSIs into
the latter, which is unlikely to work as expected.

Since it would take a ridiculous hardware topology for both regions to
be valid (which would be rather difficult to support in general), we
should be safe to assume that the presence of any hardware regions makes
the software region irrelevant. However, the IOMMU driver might still
advertise the software region by default, particularly if the hardware
regions are filled in elsewhere by generic code, so it might not be fair
for VFIO to be super-strict about not mixing them. To that end, make
vfio_iommu_has_sw_msi() robust against the presence of both region types
at once, so that we end up doing what is almost certainly right, rather
than what is almost certainly wrong.

+/**
+ * DOC: The i915 register macro definition style guide
+ *
+ * Follow the style described here for new macros, and while changing existing
+ * macros. Do **not** mass change existing definitions just to update the style.
+ *
+ * Layout
+ * ''''''
+ *
+ * Keep helper macros near the top. For example, _PIPE() and friends.
+ *
+ * Prefix macros that generally should not be used outside of this file with
+ * underscore '_'. For example, _PIPE() and friends, single instances of
+ * registers that are defined solely for the use by function-like macros.
+ *
+ * Avoid using the underscore prefixed macros outside of this file. There are
+ * exceptions, but keep them to a minimum.
+ *
+ * There are two basic types of register definitions: Single registers and
+ * register groups. Register groups are registers which have two or more
+ * instances, for example one per pipe, port, transcoder, etc. Register groups
+ * should be defined using function-like macros.
+ *
+ * For single registers, define the register offset first, followed by register
+ * contents.
+ *
+ * For register groups, define the register instance offsets first, prefixed
+ * with underscore, followed by a function-like macro choosing the right
+ * instance based on the parameter, followed by register contents.
+ *
+ * Define the register contents (i.e. bit and bit field macros) from most
+ * significant to least significant bit. Indent the register content macros
+ * using two extra spaces between ``#define`` and the macro name.
+ *
+ * For bit fields, define a ``_MASK`` and a ``_SHIFT`` macro. Define bit field
+ * contents so that they are already shifted in place, and can be directly
+ * OR'd. For convenience, function-like macros may be used to define bit fields,
+ * but do note that the macros may be needed to read as well as write the
+ * register contents.
+ *
+ * Define bits using ``(1 << N)`` instead of ``BIT(N)``. We may change this in
+ * the future, but this is the prevailing style. Do **not** add ``_BIT`` suffix
+ * to the name.
+ *
+ * Group the register and its contents together without blank lines, separate
+ * from other registers and their contents with one blank line.
+ *
+ * Indent macro values from macro names using TABs. Align values vertically. Use
+ * braces in macro values as needed to avoid unintended precedence after macro
+ * substitution. Use spaces in macro values according to kernel coding
+ * style. Use lower case in hexadecimal values.
+ *
+ * Naming
+ * ''''''
+ *
+ * Try to name registers according to the specs. If the register name changes in
+ * the specs from platform to another, stick to the original name.
+ *
+ * Try to re-use existing register macro definitions. Only add new macros for
+ * new register offsets, or when the register contents have changed enough to
+ * warrant a full redefinition.
+ *
+ * When a register macro changes for a new platform, prefix the new macro using
+ * the platform acronym or generation. For example, ``SKL_`` or ``GEN8_``. The
+ * prefix signifies the start platform/generation using the register.
+ *
+ * When a bit (field) macro changes or gets added for a new platform, while
+ * retaining the existing register macro, add a platform acronym or generation
+ * suffix to the name. For example, ``_SKL`` or ``_GEN8``.
+ *
+ * Examples
+ * ''''''''
+ *
+ * (Note that the values in the example are indented using spaces instead of
+ * TABs to avoid misalignment in generated documentation. Use TABs in the
+ * definitions.)::
+ *
+ *  #define _FOO_A                      0xf000
+ *  #define _FOO_B                      0xf001
+ *  #define FOO(pipe)                   _MMIO_PIPE(pipe, _FOO_A, _FOO_B)
+ *  #define   FOO_ENABLE                (1 << 31)
+ *  #define   FOO_MODE_MASK             (0xf << 16)
+ *  #define   FOO_MODE_SHIFT            16
+ *  #define   FOO_MODE_BAR              (0 << 16)
+ *  #define   FOO_MODE_BAZ              (1 << 16)
+ *  #define   FOO_MODE_QUX_SNB          (2 << 16)
+ *
+ *  #define BAR                         _MMIO(0xb000)

Subject: firmware: fix batched requests - wake all waiters

The firmware cache mechanism serves two purposes, the secondary purpose is
not well documented nor understood. This fixes a regression with the
secondary purpose of the firmware cache mechanism: batched requests on
successful lookups. Without this fix *any* time a batched request is
triggered, secondary requests for which the batched request mechanism
was designed for will seem to last forver and seem to never return.
This issue is present for all kernel builds possible, and a hard reset
is required.

The firmware cache is used for:

1) Addressing races with file lookups during the suspend/resume cycle
   by keeping firmware in memory during the suspend/resume cycle

2) Batched requests for the same file rely only on work from the first file
   lookup, which keeps the firmware in memory until the last
   release_firmware() is called

Batched requests *only* take effect if secondary requests come in prior to
the first user calling release_firmware(). The devres name used for the
internal firmware cache is used as a hint other pending requests are
ongoing, the firmware buffer data is kept in memory until the last user of
the buffer calls release_firmware(), therefore serializing requests and
delaying the release until all requests are done.

Batched requests wait for a wakup or signal so we can rely on the first file
fetch to write to the pending secondary requests. Commit 5b029624948d
("firmware: do not use fw_lock for fw_state protection") ported the firmware
API to use swait, and in doing so failed to convert complete_all() to
swake_up_all() -- it used swake_up(), loosing the ability for *some* batched
requests to take effect.

We *could* fix this by just using swake_up_all() *but* swait is now known
to be very special use case, so its best to just move away from it. So we
just go back to using completions as before commit 5b029624948d ("firmware:
do not use fw_lock for fw_state protection") given this was using
complete_all().

Without this fix it has been reported plugging in two Intel 6260 Wifi cards
on a system will end up enumerating the two devices only 50% of the time
[0]. The ported swake_up() should have actually handled the case with two
devices, however, *if more than two cards are used* the swake_up() would
not have sufficed. This change is only part of the required fixes for
batched requests. Another fix is provided in the next patch.

This particular change should fix the cases where more than three requests
with the same firmware name is used, otherwise batched requests will wait
for MAX_SCHEDULE_TIMEOUT and just timeout eventually.

Below is a summary of tests triggering batched requests on different
kernel builds.

Subject: firmware: fix batched requests - send wake up on failure on direct
 lookups

Fix batched requests from waiting forever on failure.

The firmware API batched requests feature has been broken since the API call
request_firmware_direct() was introduced on commit bba3a87e982ad ("firmware:
Introduce request_firmware_direct()"), added on v3.14 *iff* the firmware
being requested was not present in *certain kernel builds* [0].

When no firmware is found the worker which goes on to finish never informs
waiters queued up of this, so any batched request will stall in what seems
to be forever (MAX_SCHEDULE_TIMEOUT). Sadly, a reboot will also stall, as
the reboot notifier was only designed to kill custom fallback workers. The
issue seems to the user as a type of soft lockup, what *actually* happens
underneath the hood is a wait call which never completes as we failed to
issue a completion on error.

For device drivers with optional firmware schemes (ie, Intel iwlwifi, or
Netronome -- even though it uses request_firmware() and not
request_firmware_direct()), this could mean that when you boot a system with
multiple cards the firmware will seem to never load on the system, or that
the card is just not responsive even the driver initialization. Due to
differences in scheduling possible this should not always trigger --
one would need to to ensure that multiple requests are in place at the
right time for this to work, also release_firmware() must not be called
prior to any other incoming request. The complexity may not be worth
supporting batched requests in the future given the wait mechanism is
only used also for the fallback mechanism. We'll keep it for now and
just fix it.

Its reported that at least with the Intel WiFi cards on one system this
issue was creeping up 50% of the boots [0].

Subject: firmware: avoid invalid fallback aborts by using killable wait

Commit 0cb64249ca500 ("firmware_loader: abort request if wait_for_completion
is interrupted") added via 4.0 added support to abort the fallback mechanism
when a signal was detected and wait_for_completion_interruptible() returned
-ERESTARTSYS -- for instance when a user hits CTRL-C. The abort was overly
*too* effective.

When a child process terminates (successful or not) the signal SIGCHLD can
be sent to the parent process which ran the child in the background and
later triggered a sync request for firmware through a sysfs interface which
relies on the fallback mechanism. This signal in turn can be recieved by the
interruptible wait we constructed on firmware_class and detects it as an
abort *before* userspace could get a chance to write the firmware. Upon
failure -EAGAIN is returned, so userspace is also kept in the dark about
exactly what happened.

We can reproduce the issue with the fw_fallback.sh selftest:

Before this patch:
$ sudo tools/testing/selftests/firmware/fw_fallback.sh
...
tools/testing/selftests/firmware/fw_fallback.sh: error - sync firmware request cancelled due to SIGCHLD

After this patch:
$ sudo tools/testing/selftests/firmware/fw_fallback.sh
...
tools/testing/selftests/firmware/fw_fallback.sh: SIGCHLD on sync ignored as expected

Fix this by making the wait killable -- only killable by SIGKILL (kill -9).
We loose the ability to allow userspace to cancel a write with CTRL-C
(SIGINT), however its been decided the compromise to require SIGKILL is
worth the gains.

Chances of this issue occuring are low due to the number of drivers upstream
exclusively relying on the fallback mechanism for firmware (2 drivers),
however this is observed in the field with custom drivers with sysfs
triggers to load firmware. Only distributions relying on the fallback
mechanism are impacted as well. An example reported issue was on Android,
as follows:

1) Android init (pid=1) fork()s (say pid=42) [this child process is totally
   unrelated to firmware loading, it could be sleep 2; for all we care ]
2) Android init (pid=1) does a write() on a (driver custom) sysfs file which
   ends up calling request_firmware() kernel side
3) The firmware loading fallback mechanism is used, the request is sent to
   userspace and pid 1 waits in the kernel on wait_*
4) before firmware loading completes pid 42 dies (for any reason, even
   normal termination)
5) Kernel delivers SIGCHLD to pid=1 to tell it a child has died, which
   causes -ERESTARTSYS to be returned from wait_*
6) The kernel's wait aborts and return -EAGAIN for the
   request_firmware() caller.

Subject: firmware: send -EINTR on signal abort on fallback mechanism

Right now we send -EAGAIN to a syfs write which got interrupted.
Userspace can't tell what happened though, send -EINTR if we
were killed due to a signal so userspace can tell things apart.

This is only applicable to the fallback mechanism.

I'm not sure if this is really the case and I don't believe
this is the real fix for the bug mentioned here, but since
I don't see a reliable path when mst_port is set and when
mode_valid is requested I believe it is worth to have this
protection here.

Gen 10 should use the exact same code as Gen 9, so change the check to
take this into consideration, and also assume that future platforms
will run this code.

Also add a MISSING_CASE(), just in case we do something wrong, instead
of silently failing.

Subject: PCI: Add ACS quirk for APM X-Gene devices

The APM X-Gene PCIe root port does not support ACS at this point.  However,
the hardware provides isolation and source validation through the SMMU.
The stream ID generated by the PCIe ports contain both the bus/device/
function number as well as the port ID in its 3 most significant bits.
Turn on ACS but disable all the peer-to-peer features.

Subject: mei: exclude device from suspend direct complete optimization

MEI device performs link reset during system suspend sequence.
The link reset cannot be performed while device is in
runtime suspend state. The resume sequence is bypassed with
suspend direct complete optimization,so the optimization should be
disabled for mei devices.

Subject: thunderbolt: Do not enumerate more ports from DROM than the
 controller has

Some Alpine Ridge LP DROMs (there might be others) erroneusly list more
ports than the controller actually has. Most probably because DROM of
the full Dual/Single port Thunderbolt controller was reused for LP
version. The current DROM parser does not check the upper bound thus it
leads to crash when sw->ports[] is accessed over bounds:

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

Subject: fpga: altera-hps2fpga: fix multiple init of l3_remap_lock

The global spinlock `l3_remap_lock` is reinitialized every time the
"probe" function `alt_fpga_bridge_probe()` is called.  It should only be
initialized once.  Use `DEFINE_SPINLOCK()` to initialize it statically.

Subject: zram: rework copy of compressor name in comp_algorithm_store()

comp_algorithm_store() passes the size of the source buffer to strlcpy()
instead of the destination buffer size.  Make it explicit that the two
buffers have the same size and use strcpy() instead of strlcpy().  The
latter can be done safely since the function ensures that the string in
the source buffer is terminated.

Subject: cpufreq: intel_pstate: report correct CPU frequencies during trace

The intel_pstate CPU frequency scaling driver has always
calculated CPU frequency incorrectly.  Recent changes have
eliminted most of the issues, however the frequency reported
in the trace buffer, if used, is incorrect.

It remains desireable that cpu->pstate.scaling still be a nice
round number for things such as when setting max and min frequencies.
So the proposal is to just fix the reported frequency in the trace data.

Fixes what remains of [1].

From 28ba086ed30fb3fb714598aa029b894c3754fa7b Mon Sep 17 00:00:00 2001
From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
Date: Thu, 10 Aug 2017 00:14:45 +0200
Subject: PM / s2idle: Rename ->enter_freeze to ->enter_s2idle

Rename the ->enter_freeze cpuidle driver callback to ->enter_s2idle
to make it clear that it is used for entering suspend-to-idle and
rename the related functions, variables and so on accordingly.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Subject: PM / s2idle: Rename platform operations structure

Rename struct platform_freeze_ops to platform_s2idle_ops to make it
clear that the callbacks in it are used during suspend-to-idle
suspend/resume transitions and rename the related functions,
variables and so on accordingly.

Subject: scsi: aic7xxx: regenerate firmware files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Regenerate firmware files to make cleaner base for following fix.
This removes some unused definitions and reorders some #defines, but
the code remains the same.

Subject: scsi: mpt3sas: Fix memory allocation failure test in
 'mpt3sas_base_attach()'

In the lines above this test, 8 'kzalloc' are performed, but only 7
results are tested.

Add the missing one (i.e. '!ioc->port_enable_cmds.reply').

 minor missing code cleanup of the following older "feature"
 which also dropped the only former use of a misc device in zfcp:
 commit 663e0890e31c ("[SCSI] zfcp: remove access control tables
				    interface")

Subject: scsi: zfcp: fix queuecommand for scsi_eh commands when DIX enabled

Since commit db007fc5e20c ("[SCSI] Command protection operation"),
scsi_eh_prep_cmnd() saves scmd->prot_op and temporarily resets it to
SCSI_PROT_NORMAL.
Other FCP LLDDs such as qla2xxx and lpfc shield their queuecommand()
to only access any of scsi_prot_sg...() if
(scsi_get_prot_op(cmd) != SCSI_PROT_NORMAL).

Do the same thing for zfcp, which introduced DIX support with
commit ef3eb71d8ba4 ("[SCSI] zfcp: Introduce experimental support for
DIF/DIX").

Otherwise, TUR SCSI commands as part of scsi_eh likely fail in zfcp,
because the regular SCSI command with DIX protection data, that scsi_eh
re-uses in scsi_send_eh_cmnd(), of course still has
(scsi_prot_sg_count() != 0) and so zfcp sends down bogus requests to the
FCP channel hardware.

This causes scsi_eh_test_devices() to have (finish_cmds == 0)
[not SCSI device is online or not scsi_eh_tur() failed]
so regular SCSI commands, that caused / were affected by scsi_eh,
are moved to work_q and scsi_eh_test_devices() itself returns false.
In turn, it unnecessarily escalates in our case in scsi_eh_ready_devs()
beyond host reset to finally scsi_eh_offline_sdevs()
which sets affected SCSI devices offline with the following kernel message:

"kernel: sd H:0:T:L: Device offlined - not ready after error recovery"

Subject: scsi: zfcp: add handling for FCP_RESID_OVER to the fcp ingress path

Up until now zfcp would just ignore the FCP_RESID_OVER flag in the FCP
response IU. When this flag is set, it is possible, in regards to the
FCP standard, that the storage-server processes the command normally, up
to the point where data is missing and simply ignores those.

In this case no CHECK CONDITION would be set, and because we ignored the
FCP_RESID_OVER flag we resulted in at least a data loss or even
-corruption as a follow-up error, depending on how the
applications/layers on top behave. To prevent this, we now set the
host-byte of the corresponding scsi_cmnd to DID_ERROR.

Other storage-behaviors, where the same condition results in a CHECK
CONDITION set in the answer, don't need to be changed as they are
handled in the mid-layer already.

Following is an example trace record decoded with zfcpdbf from the
s390-tools package. We forcefully injected a fc_dl which is one byte too
small:

Timestamp      : ...
Area           : SCSI
Subarea        : 00
Level          : 3
Exception      : -

                                       ^^fr_flags==FCP_RESID_OVER
                                         ^^fr_status==SAM_STAT_GOOD
                                            ^^^^^^^^fr_resid
                 00000000 00000000

As of now, we don't actively handle to possibility that a response IU
has both flags - FCP_RESID_OVER and FCP_RESID_UNDER - set at once.

Subject: scsi: zfcp: fix capping of unsuccessful GPN_FT SAN response trace
 records

v4.9 commit aceeffbb59bb ("zfcp: trace full payload of all SAN records
(req,resp,iels)") fixed trace data loss of 2.6.38 commit 2c55b750a884
("[SCSI] zfcp: Redesign of the debug tracing for SAN records.")
necessary for problem determination, e.g. to see the
currently active zone set during automatic port scan.

While it already saves space by not dumping any empty residual entries
of the large successful GPN_FT response (4 pages), there are seldom cases
where the GPN_FT response is unsuccessful and likely does not have
FC_NS_FID_LAST set in fp_flags so we did not cap the trace record.
We typically see such case for an initiator WWPN, which is not in any zone.

Cap unsuccessful responses to at least the actual basic CT_IU response
plus whatever fits the SAN trace record built-in "payload" buffer
just in case there's trailing information
of which we would at least see the existence and its beginning.

In order not to erroneously cap successful responses, we need to swap
calling the trace function and setting the CT / ELS status to success (0).

Example trace record pair formatted with zfcpdbf:

Subject: scsi: zfcp: fix passing fsf_req to SCSI trace on TMF to correlate
 with HBA

Without this fix we get SCSI trace records on task management functions
which cannot be correlated to HBA trace records because all fields
related to the FSF request are empty (zero).
Also, the FCP_RSP_IU is missing as well as any sense data if available.

This was caused by v2.6.14 commit 8a36e4532ea1 ("[SCSI] zfcp: enhancement
of zfcp debug features") introducing trace records for TMFs but
hard coding NULL for a possibly existing TMF FSF request.
The scsi_cmnd scribble is also zero or unrelated for the TMF request
so it also could not lookup a suitable FSF request from there.

A broken example trace record formatted with zfcpdbf from the s390-tools
package:

Timestamp      : ...
Area           : SCSI
Subarea        : 00

FCP rsp inf cod: 0x00
                   ^^ no TMF response
FCP rsp IU     : 00000000 00000000 00000000 00000000
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                 00000000 00000000
                 ^^^^^^^^^^^^^^^^^ no interesting FCP_RSP_IU
Sense len      : ...
^^^^^^^^^^^^^^^^^^^^ no sense data length
Sense info     : ...
^^^^^^^^^^^^^^^^^^^^ no sense data content, even if present

There are some true cases where we really do not have an FSF request:
"rsl_fai" from zfcp_dbf_scsi_fail_send() called for early
returns / completions in zfcp_scsi_queuecommand(),
"abrt_or", "abrt_bl", "abrt_ru", "abrt_ar" from
zfcp_scsi_eh_abort_handler() where we did not get as far,
"lr_nres", "tr_nres" from zfcp_task_mgmt_function() where we're
successful and do not need to do anything because adapter stopped.
For these cases it's correct to pass NULL for fsf_req to _zfcp_dbf_scsi().

Subject: scsi: zfcp: fix missing trace records for early returns in TMF eh
 handlers

For problem determination we need to see that we were in scsi_eh
as well as whether and why we were successful or not.

The following commits introduced new early returns without adding
a trace record:

v2.6.35 commit a1dbfddd02d2
("[SCSI] zfcp: Pass return code from fc_block_scsi_eh to scsi eh")
on fc_block_scsi_eh() returning != 0 which is FAST_IO_FAIL,

v2.6.30 commit 63caf367e1c9
("[SCSI] zfcp: Improve reliability of SCSI eh handlers in zfcp")
on not having gotten an FSF request after the maximum number of retry
attempts and thus could not issue a TMF and has to return FAILED.

Subject: scsi: zfcp: fix payload with full FCP_RSP IU in SCSI trace records

If the FCP_RSP UI has optional parts (FCP_SNS_INFO or FCP_RSP_INFO) and
thus does not fit into the fsp_rsp field built into a SCSI trace record,
trace the full FCP_RSP UI with all optional parts as payload record
instead of just FCP_SNS_INFO as payload and
a 1 byte RSP_INFO_CODE part of FCP_RSP_INFO built into the SCSI record.

That way we would also get the full FCP_SNS_INFO in case a
target would ever send more than
min(SCSI_SENSE_BUFFERSIZE==96, ZFCP_DBF_PAY_MAX_REC==256)==96.

The mandatory part of FCP_RSP IU is only 24 bytes.
PAYload costs at least one full PAY record of 256 bytes anyway.
We cap to the hardware response size which is only FSF_FCP_RSP_SIZE==128.
So we can just put the whole FCP_RSP IU with any optional parts into
PAYload similarly as we do for SAN PAY since v4.9 commit aceeffbb59bb
("zfcp: trace full payload of all SAN records (req,resp,iels)").
This does not cause any additional trace records wasting memory.

Decoded trace records were confusing because they showed a hard-coded
sense data length of 96 even if the FCP_RSP_IU field FCP_SNS_LEN showed
actually less.

Since the same commit, we set pl_len for SAN traces to the full length of a
request/response even if we cap the corresponding trace.
In contrast, here for SCSI traces we set pl_len to the pre-computed
length of FCP_RSP IU considering SNS_LEN or RSP_LEN if valid.
Nonetheless we trace a hardcoded payload of length FSF_FCP_RSP_SIZE==128
if there were optional parts.
This makes it easier for the zfcpdbf tool to format only the relevant
part of the long FCP_RSP UI buffer. And any trailing information is still
available in the payload trace record just in case.

Rename the payload record tag from "fcp_sns" to "fcp_riu" to make the new
content explicit to zfcpdbf which can then pick a suitable field name such
as "FCP rsp IU all:" instead of "Sense info :"
Also, the same zfcpdbf can still be backwards compatible with "fcp_sns".

Subject: scsi: zfcp: trace HBA FSF response by default on dismiss or timedout
 late response

At the default trace level, we only trace unsuccessful events including
FSF responses.

zfcp_dbf_hba_fsf_response() only used protocol status and FSF status to
decide on an unsuccessful response. However, this is only one of multiple
possible sources determining a failed struct zfcp_fsf_req.

An FSF request can also "fail" if its response runs into an ERP timeout
or if it gets dismissed because a higher level recovery was triggered
[trace tags "erscf_1" or "erscf_2" in zfcp_erp_strategy_check_fsfreq()].
FSF requests with ERP timeout are:
FSF_QTCB_EXCHANGE_CONFIG_DATA, FSF_QTCB_EXCHANGE_PORT_DATA,
FSF_QTCB_OPEN_PORT_WITH_DID or FSF_QTCB_CLOSE_PORT or
FSF_QTCB_CLOSE_PHYSICAL_PORT for target ports,
FSF_QTCB_OPEN_LUN, FSF_QTCB_CLOSE_LUN.
One example is slow queue processing which can cause follow-on errors,
e.g. FSF_PORT_ALREADY_OPEN after FSF_QTCB_OPEN_PORT_WITH_DID timed out.
In order to see the root cause, we need to see late responses even if the
channel presented them successfully with FSF_PROT_GOOD and FSF_GOOD.

In case of problems detecting that new responses are waiting on the input
queue, we sooner or later trigger adapter recovery due to an FSF request
timeout (trace tag "fsrth_1").
FSF requests with FSF request timeout are:
typically FSF_QTCB_ABORT_FCP_CMND; but theoretically also
FSF_QTCB_EXCHANGE_CONFIG_DATA or FSF_QTCB_EXCHANGE_PORT_DATA via sysfs,
FSF_QTCB_OPEN_PORT_WITH_DID or FSF_QTCB_CLOSE_PORT for WKA ports,
FSF_QTCB_FCP_CMND for task management function (LUN / target reset).
One or more pending requests can meanwhile have FSF_PROT_GOOD and FSF_GOOD
because the channel filled in the response via DMA into the request's QTCB.

In a theroretical case, inject code can create an erroneous FSF request
on purpose. If data router is enabled, it uses deferred error reporting.
A READ SCSI command can succeed with FSF_PROT_GOOD, FSF_GOOD, and
SAM_STAT_GOOD. But on writing the read data to host memory via DMA,
it can still fail, e.g. if an intentionally wrong scatter list does not
provide enough space. Rather than getting an unsuccessful response,
we get a QDIO activate check which in turn triggers adapter recovery.
One or more pending requests can meanwhile have FSF_PROT_GOOD and FSF_GOOD
because the channel filled in the response via DMA into the request's QTCB.

                 00000000 00000000

Only with luck in both above cases, we could see a follow-on trace record
of an unsuccesful event following a successful but late FSF response with
FSF_PROT_GOOD and FSF_GOOD. Typically this was the case for I/O requests
resulting in a SCSI trace record "rsl_err" with DID_TRANSPORT_DISRUPTED
[On ZFCP_STATUS_FSFREQ_DISMISSED, zfcp_fsf_protstatus_eval() sets
ZFCP_STATUS_FSFREQ_ERROR seen by the request handler functions as failure].
However, the reason for this follow-on trace was invisible because the
corresponding HBA trace record was missing at the default trace level
(by default hidden records with tags "fs_norm", "fs_qtcb", or "fs_open").

On adapter recovery, after we had shut down the QDIO queues, we perform
unsuccessful pseudo completions with flag ZFCP_STATUS_FSFREQ_DISMISSED
for each pending FSF request in zfcp_fsf_req_dismiss_all().
In order to find the root cause, we need to see all pseudo responses even
if the channel presented them successfully with FSF_PROT_GOOD and FSF_GOOD.

Therefore, check zfcp_fsf_req.status for ZFCP_STATUS_FSFREQ_DISMISSED
or ZFCP_STATUS_FSFREQ_ERROR and trace with a new tag "fs_rerr".

It does not matter that there are numerous places which set
ZFCP_STATUS_FSFREQ_ERROR after the location where we trace an FSF response
early. These cases are based on protocol status != FSF_PROT_GOOD or
== FSF_PROT_FSF_STATUS_PRESENTED and are thus already traced by default
as trace tag "fs_perr" or "fs_ferr" respectively.

NB: The trace record with tag "fssrh_1" for status read buffers on dismiss
all remains. zfcp_fsf_req_complete() handles this and returns early.
All other FSF request types are handled separately and as described above.

Subject: scsi: zfcp: trace high part of "new" 64 bit SCSI LUN

Complements debugging aspects of the otherwise functionally complete
v3.17 commit 9cb78c16f5da ("scsi: use 64-bit LUNs").

While I don't have access to a target exporting 3 or 4 level LUNs,
I did test it by explicitly attaching a non-existent fake 4 level LUN
by means of zfcp sysfs attribute "unit_add".
In order to see corresponding trace records of otherwise successful
events, we had to increase the trace level of area SCSI and HBA to 6.

$ echo 6 > /sys/kernel/debug/s390dbf/zfcp_0.0.1880_scsi/level
$ echo 6 > /sys/kernel/debug/s390dbf/zfcp_0.0.1880_hba/level

 scan response

v2.6.33 commit dbf5dfe9dbce ("[SCSI] zfcp: Use common code definitions for
FC CT structs") replaced own definitions with common code definitions.
While FC_BA_RJT_UNABLE happens to be defined with the same value 9 as
FC_FS_RJT_UNABL and thus also works, here we should use the latter from
fc_gs.h.
See also its use in libfc's fc_disc_gpn_ft_resp().

Subject: scsi: zfcp: use common code fcp_cmnd and fcp_resp with union in
 fsf_qtcb_bottom_io

This eases crash dump analysis by automatically dissecting these
protocol headers at least somewhat rather than getting a string
interpretation of large unstructured character array buffer fields.

Also, we can get rid of some unnecessary and error-prone type casts.

This change is possible since v2.6.33 commit 4318e08c84e4
("[SCSI] zfcp: Update FCP protocol related code").

Just to silence sparse. Since zfcp only exists for s390 and
s390 is big endian, this has been working correctly without conversions
and all the new conversions are NOPs so no performance impact.

Nonetheless, use the conversion on the constant expression where possible.

NB: N_Port-IDs have always been handled with hton24 or ntoh24 conversions
because they also convert to / from character array.

Affected common code structs and .fields are:

HOT I/O PATH:
fcp_cmnd .fc_dl
   FCP command: regular SCSI I/O, including DIX case

SEMI-HOT I/O PATH:
fcp_cmnd .fc_dl
   recovery FCP command: task management function (LUN / target reset)
fcp_resp_ext
   FCP response having FCP_SNS_LEN_VAL with .fr_rsp_len .fr_sns_len
   FCP response having FCP_RESID_UNDER with .fr_resid

RECOVERY / DISCOVERY PATHS:
fc_ct_hdr .ct_cmd .ct_mr_size
   zfcp auto port scan [GPN_FT] with fc_gpn_ft_resp.fp_wwpn,
   recovery for returned port [GID_PN] with fc_ns_gid_pn.fn_wwpn,
   get symbolic port name [GSPN],
   register symbolic port name [RSPN] (NPIV only).
fc_els_rscn .rscn_plen
   incoming ELS (RSCN).
fc_els_flogi .fl_wwpn .fl_wwnn
   incoming ELS (PLOGI),
   port open response with .fl_csp.sp_bb_data .fl_cssp[0..3].cp_class,
   FCP channel physical port,
   point-to-point peer (P2P only).
fc_els_logo .fl_n_port_wwn
   incoming ELS (LOGO).
fc_els_adisc .adisc_wwnn .adisc_wwpn
   path test after RSCN for gone target port.

Since v4.10 commit 05de97003c77 ("linux/types.h: enable endian checks for
all sparse builds"), below sparse endianness reports appear by default.
Previously, one needed to pass argument CF="-D__CHECK_ENDIAN__" to make
as in: $ make C=1 CF="-D__CHECK_ENDIAN__" M=drivers/s390/scsi.

Silenced sparse warnings and one error:

Commit a54ca0f62f95 ("[SCSI] zfcp: Redesign of the debug tracing for HBA

Subject: scsi: zfcp: early returns for traces disabled via level

This patch adds early checks to avoid burning CPU cycles on
the assembly of trace entries which would be skipped anyway.

Introduce a static const variable to keep the trace level to check with
debug_level_enabled() in sync with the actual trace emit with
debug_event(). In order not to refactor the SAN tracing too much,
simply use a define instead.

This change is only for the non / semi hot paths,
while the actual (I/O) hot path was already improved earlier:
zfcp_dbf_scsi() is already guarded by its only caller _zfcp_dbf_scsi()
since commit dcd20e2316cd ("[SCSI] zfcp: Only collect SCSI debug data for
matching trace levels").
zfcp_dbf_hba_fsf_res() is already guarded by its only caller
zfcp_dbf_hba_fsf_response() since commit 2e261af84cdb ("[SCSI] zfcp: Only
collect FSF/HBA debug data for matching trace levels").

Add const to bin_attribute structures as they are only passed to the
functions system_{remove/create}_bin_file. The arguments passed are of
type const, so declare the structures to be const.

Done using Coccinelle.

Subject: scsi: mac_esp: Fix PIO transfers for MESSAGE IN phase

When in MESSAGE IN phase, the ESP device does not automatically
acknowledge each byte that is transferred by PIO. The mac_esp driver
neglects to explicitly ack them, which causes a timeout during messages
larger than one byte (e.g. tag bytes during reconnect). Fix this with an
ESP_CMD_MOK command after each byte.

The MESSAGE IN phase is also different in that each byte transferred
raises ESP_INTR_FDONE. So don't exit the transfer loop for this interrupt,
for this phase.

That resolves the "Reconnect IRQ2 timeout" error on those Macs which use
PIO transfers instead of PDMA. This patch also improves on the weak tests
for unexpected interrupts and phase changes during PIO transfers.

Subject: scsi: esp_scsi: Clean up control flow and dead code

This patch improves readability. There are no functional changes.

Since this touches on a questionable ESP_INTR_DC conditional, add some
commentary to help others who may (as I did) find themselves chasing an
"Invalid Command" error after the device flags this condition.

This cleanup also eliminates a warning from "make W=1":
drivers/scsi/esp_scsi.c: In function 'esp_finish_select':
drivers/scsi/esp_scsi.c:1233:5: warning: variable 'orig_select_state' set but not used [-Wunused-but-set-variable]

Subject: scsi: esp_scsi: Avoid sending ABORT TASK SET messages

If an LLD aborts a task set, it should complete the affected commands
with the appropriate result code. In a couple of cases esp_scsi doesn't
do so.

When the initiator receives an unhandled message, just respond by sending
a MESSAGE REJECT instead of ABORT TASK SET, and thus avoid the issue.

OTOH, a MESSAGE REJECT sent by a target can be taken as an indication
that the initiator messed up somehow. It isn't always possible to abort
correctly, so just fall back on a SCSI bus reset, which will complete the
affected commands with the appropriate result code.

For example, certain Apple (Sony) CD-ROM drives, when the non-existent
LUN 1 is scanned, can't handle the INQUIRY command. The problem is not
detected until the initiator gets a MESSAGE REJECT. Whenever esp_scsi
sees that message, it raises ATN and sends ABORT TASK SET -- but
neglects to complete the failed scmd.

The target then goes into DATA OUT phase (probably bogus), while the ESP
device goes into disconnected mode (surprising, given the bus phase).
The next Transfer Information command from esp_scsi then causes
an Invalid Command interrupt because that command is not valid when in
disconnected mode:

Subject: scsi: pm8001: fix double free in pm8001_pci_probe

In function pm8001_pci_probe(), on errors that the control flow jumps to
label err_out_ha_free, function pm8001_free() is called. In pm8001_free(),
scsi_host_put() is called to release shost, which keeps the return value
of scsi_host_alloc(). After pm8001_free() returns, kfree() is called to
free shost again, resulting in a double free bug. This patch removes
scsi_host_put() from pm8001_free() and explicitly calls scsi_host_put()
to release Scsi_Host in need.

The return value of scsi_host_alloc() should be released by
scsi_host_put(). However, in function mvs_pci_init(), kfree()
is used. This patch replaces kfree() with scsi_host_put() to avoid
possible memory leaks.

From b6d478119edeaca964b46796fd26893b81f8a561 Mon Sep 17 00:00:00 2001
From: Kevin Barnett <kevin.barnett@microsemi.com>
Date: Thu, 10 Aug 2017 13:47:03 -0500
Subject: scsi: smartpqi: update kexec and power down support

Add PQI reset to driver shutdown callback to work around controller bug.

During an 1.) OS shutdown or 2.) kexec outside of a kdump, the Linux
kernel will clear BME on our controller.

If BME is cleared during a controller/host PCIe transfer, the controller
will lock up.

So we perform a PQI reset in the driver's shutdown callback function to
eliminate the possibility of a controller/host PCIe transfer being
active when the kernel clears BME immediately after calling the driver's
shutdown callback.

Subject: scsi: hisi_sas: fix reset and port ID refresh issues

This patch provides fixes for the following issues:

1. Fix issue of controller reset required to send commands. For reset
   process, it may be required to send commands to the controller, but
   not during soft reset.  So add HISI_SAS_NOT_ACCEPT_CMD_BIT to prevent
   executing a task during this period.

2. Send a broadcast event in rescan topology to detect any topology
   changes during reset.

3. Previously it was not ensured that libsas has processed the PHY up
   and down events after reset. Potentially this could cause an issue
   that we still process the PHY event after reset. So resolve this by
   flushing shot workqueue in LLDD reset.

4. Port ID requires refresh after reset. The port ID generated after
   reset is not guaranteed to be the same as before reset, so it needs
   to be refreshed for each device's ITCT.

From 2b3833510d7f85120ba4dbaf2d5575415f09d27b Mon Sep 17 00:00:00 2001

Subject: scsi: hisi_sas: use array for v2 hw ECC errors

The code to print ECC errors in v2 hw driver is very repetitive.  This
patch condensed the code by looping an array of errors.

Subject: scsi: hisi_sas: remove repeated device config in v2 hw

This patch removes some repeated configurations:

(1) The device id of the device is already set in the alloc function, so
    we don't need to modify in free device function.

(2) Field dev_type and dev_status are configured in hisi_sas_dev_gone(),
    so there is no need for repeated config in free_device_v3_hw.

Subject: scsi: hisi_sas: service interrupt ITCT_CLR interrupt in v2 hw

This patch is a fix related to freeing a device in v2 hw driver.

Before, we polled to ITCT CLR interrupt to check if a device is free.

This was error prone, as if the interrupt doesn't occur in 10us, we miss
processing it.

To avoid this situation, service this interrupt and sync the event with
a completion.

The channel interrupt is to process all the interrupts except PHY
UP/DOWN and broadcast interrupt. So we need to clear all the interrupts
except those 3 interrupts after processing channel interrupts.

Subject: thermal: int3400_thermal: process "thermal table changed" event

Some BIOS implement ACPI notification code 0x83 to indicate active
relationship table(ART) and/or thermal relationship table(TRT) changes
to INT3400 device. This event needs to be propagated to user space so
that it can be handled by the user space thermal daemon.

Subject: thermal: core: Add some new helper functions to free resources

In order to easily free resources allocated by
'thermal_zone_create_device_groups()' we need 2 new helper functions.

The first one undoes 'thermal_zone_create_device_groups()'.
The 2nd one undoes 'create_trip_attrs()', which is a function called by
'thermal_zone_create_device_groups()'.

Subject: thermal: core: Fix resources release in error paths in
 thermal_zone_device_register()

Reorder error handling code in order to fix some resources leaks in some
cases:
   - 'tz' would leak if 'thermal_zone_create_device_groups()' fails
   - memory allocated by 'thermal_zone_create_device_groups()' would leak
     if 'device_register()' fails

With this patch, we now have 2 error handling paths: one before
'device_register()', and one after it.
This is needed because some resources are released in 'thermal_release()'.

Subject: reset: uniphier: do not use per-SoC macro for system reset block

This macro turned out not so useful as I had expected.

Hardware engineers said they would change reset bit assignments for
every SoC going forward.  This means we can not share the macros
among SoCs.  Just use primitive macros.

Subject: gpu: ipu-v3: add DRM dependency

The new PRE/PRG driver code causes a link failure when IPUv3 is built-in,
but DRM is built as a module:

drivers/gpu/ipu-v3/ipu-pre.o: In function `ipu_pre_configure':
ipu-pre.c:(.text.ipu_pre_configure+0x18): undefined reference to `drm_format_info'
drivers/gpu/ipu-v3/ipu-prg.o: In function `ipu_prg_format_supported':
ipu-prg.c:(.text.ipu_prg_format_supported+0x8): undefined reference to `drm_format_info'

Adding a Kconfig dependency on DRM means we don't run into this problem
any more. If DRM is disabled altogether, the IPUv3 driver is built
without PRE/PRG support.

Link: https://patchwork.kernel.org/patch/9636665/
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
[p.zabel@pengutronix.de: changed the dependency from DRM to DRM || !DRM,
 since the link failure only happens when DRM=m and IPUV3_CORE=y.
 Modified the commit message to reflect this.]

Subject: drm/imx: ipuv3-plane: fix YUV framebuffer scanout on the base plane

Historically, only RGB framebuffers could be assigned to the primary
plane. This changed with universal plane support. Since no colorspace
conversion was set up for the IPUv3 full plane, assigning YUV frame
buffers to the primary plane caused incorrect output.
Fix this by enabling color space conversion also for the primary plane.

Subject: drm: Document device unplug infrastructure

While at it, also ocd and give them a consistent drm_dev_ prefix, like
the other device instance functionality. Plus move the functions into
the right places.

Subject: drm: Only lastclose on unload for legacy drivers

The only thing modern drivers are supposed to do in lastclose is
restore the fb emulation state. Which is entirely optional, and
there's really no reason to do that. So restrict it to legacy drivers
(where the driver cleanup essentially happens in lastclose).

This will also allow us to share the unregister function with
drm_dev_unplug().

Quoting my reply to Alex on dri-devel:

So I think there's 3 cases:
- Trying to unload the module. You can't do that while anyone has the
fd still open, so lastclose is guaranteeed to run.
- Forcefully unbinding the driver through sysfs. Not any better, since
the can_switch stuff checks for the open count, and so will delay the
delayed switch no matter what.
- Actual hotremoval: a) not implemented since none of the drivers
taking part in vgaswitcheroo correctly unplug the drm device and b)
you can't hotremove a chip from a laptop.

v2: Extend commit message with m-l discussion.

Subject: clocksource/drivers/timer-of: Checking for IS_ERR() instead of NULL

The current code checks the return value of the of_io_request_and_map()
function as it was returning a NULL pointer in case of error.

However, it returns an error code encoded in the pointer return value, not a
NULL value. Fix this by checking the returned pointer against IS_ERR() and
return the error with PTR_ERR().

In v4.13, CLKSRC_PISTACHIO can select TIMER_OF on architectures without
GENERIC_CLOCKEVENTS, resulting in a struct clock_event_device missing
some required features and build breakage compiling timer_of.c. One of
the symbols selecting TIMER_OF is CLKSRC_PISTACHIO, so add the
dependency on GENERIC_CLOCKEVENTS.

Subject: xen: avoid deadlock in xenbus

When starting the xenwatch thread a theoretical deadlock situation is
possible:

xs_init() contains:

    task = kthread_run(xenwatch_thread, NULL, "xenwatch");
    if (IS_ERR(task))
        return PTR_ERR(task);
    xenwatch_pid = task->pid;

And xenwatch_thread() does:

    mutex_lock(&xenwatch_mutex);
    ...
    event->handle->callback();
    ...
    mutex_unlock(&xenwatch_mutex);

The callback could call unregister_xenbus_watch() which does:

    ...
    if (current->pid != xenwatch_pid)
        mutex_lock(&xenwatch_mutex);
    ...

In case a watch is firing before xenwatch_pid could be set and the
callback of that watch unregisters a watch, then a self-deadlock would
occur.

Avoid this by setting xenwatch_pid in xenwatch_thread().

Subject: xen/events: Fix interrupt lost during irq_disable and irq_enable

Here is a device has xen-pirq-MSI interrupt. Dom0 might lost interrupt
during driver irq_disable/irq_enable. Here is the scenario,
 1. irq_disable -> disable_dynirq -> mask_evtchn(irq channel)
 2. dev interrupt raised by HW and Xen mark its evtchn as pending
 3. irq_enable -> startup_pirq -> eoi_pirq ->
    clear_evtchn(channel of irq) -> clear pending status
 4. consume_one_event process the irq event without pending bit assert
    which result in interrupt lost once
 5. No HW interrupt raising anymore.

Now use enable_dynirq for enable_pirq of xen_pirq_chip to remove
eoi_pirq when irq_enable.

Commit c54451a "iommu/arm-smmu: Fix the error path in arm_smmu_add_device"
removed fwspec assignment in legacy_binding path as redundant which is
wrong. It needs to be updated after fwspec initialisation in
arm_smmu_register_legacy_master() as it is dereferenced later. Without
this there is a NULL-pointer dereference panic during boot on some hosts.

Subject: drm/i915/fbc: only update no_fbc_reason when active

In our snb farm in CI we have plenty of underruns, but not enough
stolen memory to enable fbc. Which means every time there's an
underrun the no_fbc_reason swichtes to something that makes
kms_frontbuffer_tracking fail instead of skip, adding massive amounts
of additional noise to igt test runs.

Make sure we don't try to disable fbc when it's off already.

v2: Squash in additional WARN_ON suggestion from Chris.

Subject: drm/hisilicon: switch to drm_*_get(), drm_*_put() helpers

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

Subject: drm/mgag200: switch to drm_*_get(), drm_*_put() helpers

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

Subject: drm/i915: make structure intel_sprite_plane_funcs static

The structure intel_sprite_plane_funcs is local to the source
and does not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'intel_sprite_plane_funcs' was not declared. Should it be static?

I added a proper pin control driver for the Gemini SoC, so retire
this custom code and rely on the pin controller to set up the pads.

The "IOMUX" which is routing signals between the ATA and SATA
bridge inside of the chip is not about pin control and remains in
place.

Several legacy devices such as Geode-based Cisco ASA appliances

with different PCI id than existing one. Using pata_generic is
not always feasible as at least DB800 requires MSR quirk from
pata_cs5536 to be used with vendor firmware.

Different from SKL we don't need ctrl1 and cfgcr2, but

Subject: drm/i915: Simplify hpd pin to port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We will soon need to make that pin port association per
platform, so let's try to simplify it beforehand.

Also we are moving the backwards port to pin
here as well so let's use a standardized way.

One extra possibility here would be to add a
MISSING_CASE along with PORT_NONE, but I don't want
to change this behaviour for now.

Subject: drm/i915: Introduce intel_hpd_pin function.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The idea is to have an unique place to decide the pin-port
per platform.

So let's create this function now without any functional
change. Just adding together code from hdmi and dp together.

v2: Add missing pin for port A.
v3: Fix typo on subject.
    Avoid behaviour change so add WARN_ON and return
    if port A on HDMI. (by DK).

Subject: geneve: use netlink_ext_ack for error reporting in rtnl operations

Add extack error messages for failure paths while creating/modifying
geneve devices. Once extack support is added to iproute2, more
meaningful and helpful error messages will be displayed making it easy
for users to discern what went wrong.

Before:

=======
$ ip link add gen1 address 0:1:2:3:4:5:6 type geneve id 200 \
  remote 192.168.13.2
RTNETLINK answers: Invalid argument

After:
======
$ ip link add gen1 address 0:1:2:3:4:5:6 type geneve id 200 \
  remote 192.168.13.2
Error: Provided link layer address is not Ethernet

Also, netdev_dbg() calls used to log errors associated with Netlink
request have been removed.

Subject: net: sched: use newly added classid identity helpers

Instead of checking handle, which does not have the inner class
information and drivers wrongly assume clsact->egress as ingress, use
the newly introduced classid identification helpers.

Subject: netvsc: don't signal host twice if empty

When hv_pkt_iter_next() returns NULL, it has already called
hv_pkt_iter_close(). Calling it twice can lead to extra host signal.

Subject: netvsc: propagate MAC address change to VF slave

If VF is slaved to synthetic device, then any change to netvsc
MAC address should be propagated to the slave device.

If slave device doesn't support MAC address change then it
should also be an error to attempt to change synthetic NIC MAC
address.

It also fixes the error unwind in the original code.
If give a bad address, the old code would change the device
MAC address anyway.

Subject: netvsc: no need to allocate send/receive on numa node

The send and receive buffers are both per-device (not per-channel).
The associated NUMA node is a property of the CPU which is per-channel
therefore it makes no sense to force the receive/send buffer to be
allocated on a particular node (since it is a shared resource).

Subject: netvsc: allow controlling send/recv buffer size

Control the size of the buffer areas via ethtool ring settings.
They aren't really traditional hardware rings, but host API breaks
receive and send buffer into chunks. The final size of the chunks are
controlled by the host.

The default value of send and receive buffer area for host DMA
is much larger than it needs to be. Experimentation shows that
4M receive and 1M send is sufficient.

Subject: netvsc: keep track of some non-fatal overload conditions

Add ethtool statistics for case where send chimmeny buffer is
exhausted and driver has to fall back to doing scatter/gather
send. Also, add statistic for case where ring buffer is full and
receive completions are delayed.

Subject: bonding: require speed/duplex only for 802.3ad, alb and tlb

The patch c4adfc822bf5 ("bonding: make speed, duplex setting consistent
with link state") puts the link state to down if
bond_update_speed_duplex() cannot retrieve speed and duplex settings.
Assumably the patch was written with 802.3ad mode in mind which relies
on link speed/duplex settings. For other modes like active-backup these
settings are not required. Thus, only for these other modes, this patch
reintroduces support for slaves that do not support reporting speed or
duplex such as wireless devices. This fixes the regression reported in
bug 196547 (https://bugzilla.kernel.org/show_bug.cgi?id=196547).

Fixes: c4adfc822bf5 ("bonding: make speed, duplex setting consistent
with link state")

Subject: net: stmmac: dwmac-rk: Add integrated PHY support for rk3228

There is only one mac controller in rk3228, which could connect to
external PHY or integrated PHY, use the grf_com_mux bit15 to route
external/integrated PHY.

Subject: net: stmmac: dwmac-rk: Add integrated PHY supprot for rk3328

There are two mac controllers in the rk3328, the one connects
to external PHY, and the other one connects to integrated PHY.
Like the mac of external PHY, the integrated PHY's mac also
needs to configure the related mac registers at GRF.

Subject: net: stmmac: Use the right logging function in stmmac_mdio_register

Currently, the function stmmac_mdio_register() is only used by
stmmac_dvr_probe() from stmmac_main.c, in order to register the MDIO bus
and probe information about the PHY. As this function is called before
calling register_netdev(), all messages logged from stmmac_mdio_register
are prefixed by "(unnamed net_device)". The goal of netdev_info or
netdev_err is to dump useful infos about a net_device, when this data
structure is partially initialized, there is no point for using these
functions.

This commit fixes the issue by replacing all netdev_*() by the
corresponding dev_*() function for logging. The last netdev_info is
replaced by phy_attached_info(), as a valid phydev can be used at this
point.

The Flower app may receive a request to update the MTU of a representor
netdev upon receipt of a control message from the firmware. This requires
the RTNL lock which needs to be taken outside of the packet processing
path.

As a handling of this correctly seems a little to invasive for a fix simply
skip setting the MTU for now.

Subject: nfp: send control message when MAC representors are created

The firmware expects a MAC_REPR control message when a MAC representor
is created. The driver should expect a PORTMOD message to follow which
will provide the link states of the physical port associated with the MAC
representor.

Subject: mISDN: Fix null pointer dereference at mISDN_FsmNew

If mISDN_FsmNew() fails to allocate memory for jumpmatrix
then null pointer dereference will occur on any write to
jumpmatrix.

The patch adds check on successful allocation and
corresponding error handling.

Subject: libnvdimm, pfn, dax: show supported dax/pfn region alignments in
 sysfs

The alignment of a DAX and PFN regions dictates the page sizes that can
be used to map the region. Even if the hardware page sizes are known the
actual range of supported page sizes that can be used with DAX depends
on the kernel configuration. As a result it's best that the kernel
advertises the alignments that should be used with these region types.

This patch adds the 'supported_alignments' region attribute to expose
this information to userspace.

Subject: i2c: constify internal structures

Check for i2c_algorithm and i2c_adapter_quirks structures that are only
stored in the algo and quirks fields of an i2c_adapter structure
correspondingly. These fields are declared const, so i2c_algorithm and
i2c_adapter_quirks structures that have this property can be declared
as const also.

Subject: staging: iio: adc: fix error return code in ad7606_par_probe()

platform_get_irq() returns an error code, but the ad7606_par driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

Subject: drm/i915: Suppress switch_mm emission between the same aliasing_ppgtt

When switching between contexts using the aliasing_ppgtt, the VM is
shared. We don't need to reload the PD registers unless they are dirty.

Martin Peres reported an issue that looks like corruption between
Haswell context switches, bisecting to commit f9326be5f1d3 ("drm/i915:
Rearrange switch_context to load the aliasing ppgtt on first use").
Switching between the same mm (the aliasing_ppgtt is used for all
contexts in this case) should be a nop, but appears to trigger some
side-effects in the context switch. However, as we know the switch
is redundant in this case, we can skip it and continue to ignore the
issue until somebody feels strong enough to investigate full-ppgtt on
gen7 again!

Except.. Martin was using full-ppgtt which is not supported as it
doesn't work correctly yet. So whilst the bisect did yield valuable
information about the failures, the fix should not have any user impact
under default settings, with the exception of a slightly lower
throughput on xcs as the VM would always be reloaded.

v2: Also remember to set the legacy_active_context following the switch
on xcs (commit e8a9c58fcd9a ("drm/i915: Unify active context tracking
between legacy/execlists/guc"))

Subject: mtd: nand: Rename nand.h into rawnand.h

We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

Subject: platform/x86: hp-wmi: Correctly determine method id in WMI calls

The WMI queries are performed by evaluating the WMPV() method from ACPI
DSDT tables, and it takes three arguments: instance index, method id and
input data (buffer).

Currently the method id is hard-coded to 0x3 in hp_wmi_perform_query()
which means that it will perform WMI calls that expect an output data of
size 0x80 (128). The output size is usually OK for the WMI queries we
perform, however it would be better to pick the correct one before
evaluating the WMI method.

Which correct method id to choose can be figured out by looking at the
following ASL code from WVPI() method:

...
Name (PVSZ, Package (0x05)
            {
            Zero,
            0x04,
            0x80,
            0x0400,
            0x1000
            })
Store (Zero, Local0)
If (LAnd (LGreaterEqual (Arg1, One), LLessEqual (Arg1, 0x05)))
{
    Store (DerefOf (Index (PVSZ, Subtract (Arg1, One))), Local0)
}
...

Arg1 is the method id and PVSZ is the package used to index the
corresponding output size; 1 -> 0, 2 -> 4, 3 -> 128, 4 -> 1024, 5 ->
4096.

This patch maps the output size passed in hp_wmi_perform_query() to the
correct method id before evaluating the WMI method.

Subject: platform/x86: intel_mid_powerbtn: fix error return code in
 mid_pb_probe()

platform_get_irq() returns an error code, but the intel_mid_powerbtn
driver ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print error message and propagate the return value of platform_get_irq
on failure.

This issue was detected with the help of Coccinelle.

According to Hans de Goede, WMI interface of thh peaq-wmi module has 10
instances but corresponding ACPI WMBC method does not check Arg0 (instance
number) at all. Therefore evaluate WMI method with first instance number
(0x0) instead of second (0x1).

Subject: platform/x86: intel_pmc_core: Make the driver PCH family agnostic

Although this driver did pretty good job in abstracting PCH specific
interfaces, but still there are some loose ends. For example
SLP_S0 counter (for reading SLP_S0 residency), PM config offset (for
checking permissions to read XRAM) and PPFEAR offset (for reading IP
status) is still hardcoded for a specific family of PCH.

This change extended the struct pmc_reg_map to allow per family
configuration of offsets and bits.

No functional change is expected with this change. This change allows
seamless additions to new PCH and create a baseline for other platform
specific extensions.

Subject: hwmon: (stts751) buffer overrun on wrong chip configuration

If stts751 hw by some reason reports conversion rate bigger then 9:
        ret = i2c_smbus_read_byte_data(priv->client, STTS751_REG_RATE);
then dereferencing stts751_intervals[priv->interval] leads to buffer
overrun.

The patch adds sanity check for value stored on chip.

Found by Linux Driver Verification project (linuxtesting.org).

Subject: hwmon: (core) constify thermal_zone_of_device_ops structures

The thermal_zone_of_device_ops structure is only passed as the fourth
argument to devm_thermal_zone_of_sensor_register, which is declared
as const.  Thus the thermal_zone_of_device_ops structure itself can
be const.

Done with the help of Coccinelle.

Subject: hwmon: (it87) Split out chip registers setting code on probe path

This commit splits out chip registers setting code on probe path to
separate functions so they can be reused for setting the device properly
again when system resumes from suspend.

While we are at it let's also make clear that on IT8720 and IT8782 it's
the VCCH5V line that is (possibly) routed to in7.
This will make it consistent with a similar message that it printed on
IT8783.

Subject: hwmon: (it87) Reapply probe path chip registers settings after resume

After a suspend / resume cycle we possibly need to reapply chip registers
settings that we had set or fixed in a probe path, since they might have
been reset to default values or set incorrectly by a BIOS again.

Tested on a Gigabyte M720-US3 board, which requires routing internal VCCH5V
to in7 (and had it wrong again on resume from S3).

Subject: hwmon: (pmbus): Access word data for STATUS_WORD

Pmbus always reads byte data from the status register, even if
configured to use STATUS_WORD. Use a function pointer to read the
correct amount of data from the registers.
Also switch to try STATUS_WORD first before STATUS_BYTE on init.

Subject: hwmon: (pmbus): Add generic alarm bit for iin and pin

Add PB_STATUS_INPUT as the generic alarm bit for iin and pin. We also
need to redo the status register checking before setting up the boolean
attribute, since it won't necessarily check STATUS_WORD if the device
doesn't support it, which we need for this bit.

Subject: hwmon: (aspeed-pwm-tacho) cooling device support.

Add support in aspeed-pwm-tacho driver for cooling device creation.
This cooling device could be bound to a thermal zone
for the thermal control. Device will appear in /sys/class/thermal
folder as cooling_deviceX. Then it could be bound to particular
thermal zones. Allow specification of the cooling levels
vector - PWM duty cycle values in a range from 0 to 255
which correspond to thermal cooling states.

Subject: i2c-cht-wc: Add Intel Cherry Trail Whiskey Cove SMBUS controller
 driver

The Intel Cherry Trail Whiskey Cove PMIC does not contain a builtin
battery charger, instead boards with this PMIC use an external TI
bq24292i charger IC, which is connected to a SMBUS controller built into
the PMIC.

This commit adds an i2c-bus driver for the PMIC's builtin SMBUS
controller. The probe function for this i2c-bus will also register an
i2c-client for the TI bq24292i charger after the i2c-bus has been
registered.

Note that several device-properties are set on the client-device to
tell the bq24190 power-supply driver to integrate the Whiskey Cove PMIC
and e.g. use the PMIC's BC1.2 detection (through extcon) to determine
the maximum input current.

Subject: tap: use build_skb() for small packet

We use tun_alloc_skb() which calls sock_alloc_send_pskb() to allocate
skb in the past. This socket based method is not suitable for high
speed userspace like virtualization which usually:

- ignore sk_sndbuf (INT_MAX) and expect to receive the packet as fast as
  possible
- don't want to be block at sendmsg()

To eliminate the above overheads, this patch tries to use build_skb()
for small packet. We will do this only when the following conditions
are all met:

- TAP instead of TUN
- sk_sndbuf is INT_MAX
- caller don't want to be blocked
- zerocopy is not used
- packet size is smaller enough to use build_skb()

Pktgen from guest to host shows ~11% improvement for rx pps of tap:

Before: ~1.70Mpps
After : ~1.88Mpps

What's more important, this makes it possible to implement XDP for tap
before creating skbs.

Subject: tap: XDP support

This patch tries to implement XDP for tun. The implementation was
split into two parts:

- fast path: small and no gso packet. We try to do XDP at page level
  before build_skb(). For XDP_TX, since creating/destroying queues
  were completely under control of userspace, it was implemented
  through generic XDP helper after skb has been built. This could be
  optimized in the future.
- slow path: big or gso packet. We try to do it after skb was created
  through generic XDP helpers.

Test were done through pktgen with small packets.

xdp1 test shows ~41.1% improvement:

Before: ~1.7Mpps
After:  ~2.3Mpps

xdp_redirect to ixgbe shows ~60% improvement:

Before: ~0.8Mpps
After:  ~1.38Mpps

Subject: vxlan: change vxlan_[config_]validate() to use netlink_ext_ack for
 error reporting

The kernel log is not where users expect error messages for netlink
requests; as we have extended acks now, we can replace pr_debug() with
NL_SET_ERR_MSG_ATTR().

Subject: bonding: ratelimit failed speed/duplex update warning

bond_miimon_commit() handles the UP transition for each slave of a bond
in the case of MII. It is triggered 10 times per second for the default
MII Polling interval of 100ms. For device drivers that do not implement
__ethtool_get_link_ksettings() the call to bond_update_speed_duplex()
fails persistently while the MII status could remain UP. That is, in
this and other cases where the speed/duplex update keeps failing over a
longer period of time while the MII state is UP, a warning is printed
every MII polling interval.

To address these excessive warnings net_ratelimit() should be used.
Printing a warning once would not be sufficient since the call to
bond_update_speed_duplex() could recover to succeed and fail again
later. In that case there would be no new indication what went wrong.

Subject: of_mdio: merge branch tails in of_phy_register_fixed_link()

Looks  like gcc isn't always able to figure  out that 3 *if* branches in
of_phy_register_fixed_link() calling fixed_phy_register() at their ends
are similar enough and thus can be merged. The "manual" merge saves 40
bytes of the object code (AArch64 gcc 4.8.5), and still saves 12 bytes
even  if gcc was able to merge the branch tails (ARM gcc 4.8.5)...

The array guest_offloads is local to the source and does not need to
be in global scope, so make it static. Also tweak formatting.

Cleans up sparse warnings:
symbol 'guest_offloads' was not declared. Should it be static?

Subject: brcmfmac: feature check for multi-scheduled scan fails on bcm4343x
 devices

The firmware feature check introduced for multi-scheduled scan turned out
to be failing for bcm4343{0,1,8} devices resulting in a firmware crash.
The reason for this crash has not yet been root cause so this patch avoids
the feature check for those device as a short-term fix.

Subject: gpio: reject invalid gpio before getting gpio_desc

Check user-given gpio number and reject it before
calling gpio_to_desc() because gpio_to_desc() is
for kernel driver and it expects given gpio number
is valid (means 0 to 511).
If given number is invalid, gpio_to_desc() calls
WARN() and dump registers and stack for debug.
This means user can easily kick WARN() just by
writing invalid gpio number (e.g. 512) to
/sys/class/gpio/export.

Subject: gpio: mvebu: Fix cause computation in irq handler

When switching to regmap, the way to compute the irq cause was
reorganized. However while doing it, a typo was introduced: a 'xor'
replaced a 'and'.

This lead to wrong behavior in the interrupt handler ans one of the
symptom was wrong irq handler called on the Armada 388 GP:
"->handle_irq():  c016303c,
handle_bad_irq+0x0/0x278
->irq_data.chip(): c0b0ec0c,
0xc0b0ec0c
->action():   (null)
   IRQ_NOPROBE set
 IRQ_NOREQUEST set
unexpected IRQ trap at vector 00

Subject: pinctrl: qcom: ipq4019: add most remaining pin definitions

This patch adds multiple pinctrl functions and mappings
for SDIO, NAND, I2S, WIFI, PCIE, LEDs, etc... that have
been missing from the current minimal version.

This patch has been updated from the original version
that was posted by Ram Chandra Jangir on the LEDE-DEV ML:
<https://patchwork.ozlabs.org/patch/752962/>. A short
summary of the changes are documented in the device-tree
patch of this series:
"dt-bindings: pinctrl: add most other IPQ4019 pin functions and groups"

Subject: pinctrl: msm: add support to configure ipq40xx GPIO_PULL bits

GPIO_PULL bits configurations in TLMM_GPIO_CFG register
differs for IPQ40xx from rest of the other qcom SoCs.
As it does not support the keeper state and therefore can't
support bias-bus-hold property.

This patch adds a pull_no_keeper setting which configures the
msm_gpio_pull bits for ipq40xx. This is required to fix the
proper configurations of gpio-pull bits for nand pins mux.

IPQ40xx SoC:
2'b10: Internal pull up enable.
2'b11: Unsupport

For other SoC's:
2'b10: Keeper
2'b11: Pull-Up

Note: Due to pull_no_keeper length, all kerneldoc entries
in the msm_pinctrl_soc_data struct had to be realigned.

Subject: pinctrl: sunxi: add support of R40 to A10 pinctrl driver

R40 is said to be an upgrade of A20, and its pin configuration is also
similar to A20 (and thus similar to A10).

Add support for R40 to the A10 pinctrl driver.

Subject: pinctrl: sunxi: rename R_PIO i2c pin function name

The I2C pin functions in R_PIO used to be named "s_twi".

As we usually use the name "i2c" instead of "twi" in the mainline
kernel, change these names to "s_i2c" for consistency.

The "s_twi" functions are not yet referenced by any device trees in
mainline kernel so I think it's safe to change the name.

Subject: pinctrl: uniphier: fix pin_config_get() for input-enable

For LD11/LD20 SoCs (capable of per-pin input enable), iectrl bits are
located across multiple registers.  So, the register offset must be
taken into account.  Otherwise, wrong input-enable status is displayed.

While we here, rename the macro because it is a base address.

Subject: pinctrl: uniphier: clean up GPIO port muxing

There are a bunch of GPIO muxing data, but most of them are actually
unneeded because GPIO-to-pin mapping can be specified by "gpio-ranges"
DT properties.

Tables that contain a set of GPIO pins are still needed for the named
mapping by "gpio-ranges-group-names".  This is a much cleaner way for
UniPhier SoC family where GPIO numbers are not straight mapped to pin
numbers.

Subject: pinctrl: uniphier: omit redundant input enable bit information

For LD11/20 SoCs (capable of per-pin input enable), the iectrl bit
number matches its pin number.  So, this is redundant information.
Instead, we just need a flag to know if the iectrl gating exists or not.

With this refactoring, 5 bits in pin data will be saved.

Subject: pinctrl: imx: switch to use the generic pinmux property

The generic pinmux property seems to be more suitable for IMX.
So we change to use 'pinmux' instead of 'pins'.

Subject: pinctrl: imx: add imx7ulp driver

i.MX 7ULP has three IOMUXC instances: IOMUXC0 for M4 ports,
IOMUXC1 for A7 ports and IOMUXC DDR for DDR interface.

This patch adds the IOMUXC1 support for A7.
It only supports generic pin config.

Subject: pinctrl: imx: remove gpio_request_enable and gpio_disable_free

gpio_request_enable/disable_free actually are not quite necessary as
standard IMX pinctrl binding already sets GPIO mux from device tree,
e.g. VF610_PAD_PTB20__GPIO_42 or MX7D_PAD_SD2_CD_B__GPIO5_IO9
No need to do it again in gpio_request_enable.

And according to Stefan:
"For all GPIO I checked in upstream device trees we assign a pinctrl
to the same node, so in all cases gpio_request_enable/disable is really
unnecessary."

So it should be safe to simply remove it.

Note that this changes semantics for Vybrid, e.g.
"The two functions have been introduced for Vybrid (through
SHARE_MUX_CONF_REG) and mux pins as GPIOs automatically when a GPIO
gets requested. The automatic mux is optional by the pinmux/gpio
subsystem semantics, and other NXP devices do not use it, instead an
explicit pinctrl node is added in the device tree to mux GPIOs where
required. Hence this change aligns Vybrid to other NXP (i.MX) devices.

Note that all upstream device tree assign proper pinctrl properties
where GPIOs are used so no change is necessary for device trees."

Subject: pinctrl: imx: make imx_pmx_ops.gpio_set_direction platform specific
 callbacks

Various IMX platforms may have different imx_pmx_ops.gpio_set_direction
implementations, so let's make it platform specific callbacks instead of
the fixed common one.

Currently only VF610 platform implements it. No function level changes.

WARN_ON causes a backtrace to get logged which is only useful for
kernel bugs. For signalling a firmware bug dev_warn(dev, FW_BUG "...")
should be used.

This fixes users running userspace software to monitor kernel oopses
getting a false positive bug-report every boot because of the wrong
use of WARN_ON.

Subject: pinctrl: zte: fix 'functions' allocation in zx_pinctrl_build_state()

It fixes the following Smatch static check warning:

 drivers/pinctrl/zte/pinctrl-zx.c:338 zx_pinctrl_build_state()
 warn: passing devm_ allocated variable to kfree.

As we will be calling krealloc() on pointer 'functions', which means
kfree() will be called in there, devm_kzalloc() shouldn't be used with
the allocation in the first place.  Fix the warning by calling kcalloc()
and managing the free procedure in error path on our own.

Subject: pinctrl: aspeed: g4: Add USB device and host support

Implement the AST2400 USB functions as described by the devicetree
bindings. Three ports are fully documented in the datasheet and exposed
through the bindings and pinctrl, though there are remnants of
documentation for a fourth port muxed with GPIO pins GPIOQ6 and GPIOQ7.
The implementation is updated to reflect this but the function and
group are not exposed.

Disregarding the mostly undocumented fourth port, the USB functions are
an outlier with respect to the rest of the muxed functionality on the
AST2400 as GPIO is not supported on these pins.

Subject: pinctrl: stm32: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: pinctrl: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

There are 3 IP blocks pin routes need to be switched, that are
emmc-cmd, spi, i2s. And there are some pins need to be recalced,
which are gpio2c4~gpio2c7 and gpio2d0.

Subject: pinctrl: sirf: atlas7: fix of_irq_get() error check

of_irq_get() may return  any negative error number as well as 0 on failure,
while the driver only checks for -EPROBE_DEFER, blithely continuing with
the call to gpiochip_set_chained_irqchip() -- that function expects the
parent IRQ as *unsigned int*, so would probably do nothing  when a large
IRQ number resulting from a conversion of a negative error number is passed
to it, however passing 0 would probably work but the driver won't receive
valid GPIO bank interrupts.

Check for 'ret <= 0' instead and return -ENXIO from the driver's probe iff
of_irq_get() returned 0.

Subject: pinctrl: sunxi: fix V3s pinctrl driver IRQ bank base

The V3s pin controller doesn't have the bank 0 (starts at address
0x200), which is like A33. However, this is not worked around when
developing the driver, which makes IRQ not working.

Fix the IRQ bank base.

Since commit 58957d2edfa1 ("pinctrl: Widen the generic pinconf argument

UniPhier pinctrl drivers do not support debouncing, so u16 is working,
but align the argument type to u32 for consistency.

formally requested.  This allows the GPIO driver to block access to
unavailable GPIOs, which makes it easier for some drivers to support
sparse GPIO maps.

Subject: gpiolib: allow gpio irqchip to map irqs dynamically

Now IRQ mappings are always created for all (allowed) GPIOs in gpiochip in
gpiochip_irqchip_add_key() which goes against the idea of SPARSE_IRQ and,
as result, leads to:
 - increasing of memory consumption for IRQ descriptors most of which will
never ever be used (espessially on platform with a high number of GPIOs).
(sizeof(struct irq_desc) == 256 on my tested platforms)
 - imposibility to use GPIO irqchip APIs by gpio drivers when HW implements
GPIO IRQ functionality as IRQ crossbar/router which has only limited
number of IRQ outputs (example from [1], all GPIOs can be mapped on only 8
IRQs).

Hence, remove static IRQ mapping code from gpiochip_irqchip_add_key() and
instead replace irq_find_mapping() with irq_create_mapping() in
gpiochip_to_irq(). Also add additional gpiochip_irqchip_irq_valid() calls
in gpiochip_to_irq() and gpiochip_irq_map().

After this change gpio2irq mapping will happen the following way when GPIO
irqchip APIs are used by gpio driver:
 - IRQ mappings will be created statically if driver passes first_irq>0
vlaue in gpiochip_irqchip_add_key().
 - IRQ mappings will be created dynamically from gpio_to_irq() or
of_irq_get().

Tested on am335x-evm and dra72-evm-revc.
- dra72-evm-revc: number of created irq mappings decreased from 402 -> 135
  Mem savings 267*256 = 68352 (66kB)
- am335x-evm: number of created irq mappings decreased from 188 -> 63
  Mem savings 125*256 = 32000 (31kB)

Subject: gpio: rcar: add gen[123] fallback compatibility strings

Add fallback compatibility string for R-Car Gen 1, 2 and 3.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Also deprecate renesas,gpio-rcar as its name is more generic than its
implementation.

Errors from enable_irq_wake() in gpio_set_wake_irq() were silently ignored.
Thus led to the problem that gpio_set_wake_irq() always returned
successfully, even if enable_irq_wake() returned an error.

Subject: gpio: tegra: Use platform_get_irq()

Instead of using platform_get_resource() and getting the interrupts from
the resource, use platform_get_irq() which is slightly easier to use and
covers some special cases that the former doesn't.

Subject: pinctrl: check ops->pin_config_set in pinconf_set_config()

pinconf_set_config() is called by pinctrl_gpio_set_config().
If a GPIO driver is backed by a pinctrl driver and it does not
support .pin_config_set() hook, it causes NULL pointer dereference.

Fixes: 15381bc7c7f5 ("pinctrl: Allow configuration of pins from gpiolib based drivers")

Subject: pinctrl: add a Gemini SoC pin controller

This adds a pin control (only multiplexing) driver for the Gemini
SoC so we can sort out this complex platform in an orderly manner.

This driver will detect the chip/package version as SL3512 or SL3516
(also known as CS3512 and CS3516 etc) and register the apropriate
pin set.

From 539b7a39f5ec4cfb573af1e65aeed0edf32be8bb Mon Sep 17 00:00:00 2001
From: Thierry Reding <treding@nvidia.com>

Subject: gpio: tegra: Use unsigned int where possible

In most of the cases, integers in this file can't be negative, so the
type can be more restricted for clarity.

From the datasheet, the GPIO interface is identical to IT8728 (same
description), so just add it to the same case as the other chip.

platform_get_irq() returns an error code, but the gpio-msic driver
ignores it and always returns -EINVAL. This is not correct, and
prevents -EPROBE_DEFER from being propagated properly.

Notice that platform_get_irq() no longer returns 0 on error:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af

Subject: gpio: vf610: add imx7ulp support

The Rapid General-Purpose Input and Output with 2 Ports (RGPIO2P)
on MX7ULP is similar to GPIO on Vibrid. But unlike Vibrid, the
RGPIO2P has an extra Port Data Direction Register (PDDR) used
to configure the individual port pins for input or output.

We introduce a bool have_paddr with fsl_gpio_soc_data data
to distinguish this differences. And we support getting the output
status by checking the GPIO direction in PDDR.

This patch adds support for TPS68470 GPIOs.
There are 7 GPIOs and a few sensor related GPIOs.
These GPIOs can be requested and configured as
appropriate.

The GPIOs are also provided with descriptive names.
However, the typical use case is that the OS GPIO
driver will interact with TPS68470 GPIO driver
to configure these GPIOs, as requested by the
platform firmware.

Subject: drm/atomic: Handle -EDEADLK with out-fences correctly

complete_crtc_signaling is freeing fence_state, but when retrying
num_fences and fence_state are not zero'd. This caused duplicate
fd's in the fence_state array, followed by a BUG_ON in fs/file.c
because we reallocate freed memory, and installing over an existing
fd, or potential other fun.

Zero fence_state and num_fences correctly in the retry loop, which
allows kms_atomic_transition to pass.

Subject: gpio: zynq: Provided workaround for GPIO

This patch provides workaround in the gpio driver
for Zynq and ZynqMP Platforms by reading pin value
of EMIO banks through DATA register as it was unable
to read the value of it from DATA_RO register.

Subject: drm/i915: Avoid the gpu reset vs. modeset deadlock

... using the biggest hammer we have. This is essentially a weaponized
version of the timeout-based wedging Chris added in

commit 36703e79a982c8ce5a8e43833291f2719e92d0d1
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Thu Jun 22 11:56:25 2017 +0100

    drm/i915: Break modeset deadlocks on reset

Because defense-in-depth is good it's good to still have both. Also
note that with the locking change we can now restrict this a lot (old
gpus and special testing only), so this doesn't kill the TDR benefits
on at least anything remotely modern.

And futuremore with a few tricks it should be possible to make a much
more educated guess about whether an atomic commit is stuck waiting on
the gpu (atomic_t counting the pending i915_sw_fence used by the
atomic modeset code should do it), so we can improve this.

But for now just start with something that is guaranteed to recover
faster, for much better CI througput.

This defacto reverts TDR on these platforms, but there's not really a
single commit to specify as the sole offender.

v2: Add a debug message to explain what's going on. We can't DRM_ERROR
because that spams CI. And the timeout based fallback still prints a
DRM_ERROR, in case something goes wrong.

v3: Fix comment layout (Michel)

Fixes: 4680816be336 ("drm/i915: Wait first for submission, before waiting for request completion")
Fixes: 221fe7994554 ("drm/i915: Perform a direct reset of the GPU from the waiter")

Subject: drm/i915: Push i915_sw_fence_wait into the nonblocking atomic commit

Blocking in a worker is ok, that's what the unbound_wq is for. And it
unifies the paths between the blocking and nonblocking commit, giving
me just one path where I have to implement the deadlock avoidance
trickery in the next patch.

I first tried to implement the following patch without this rework, but
force-completing i915_sw_fence creates some serious challenges around
properly cleaning things up. So wasn't a feasible short-term approach.
Another approach would be to simple keep track of all pending atomic
commit work items and manually queue them from the reset code. With the
caveat that double-queue in case we race with the i915_sw_fence must be
avoided. Given all that, taking the cost of a double schedule in atomic
for the short-term fix is the best approach, but can be changed in the future of course.

v2: Amend commit message (Chris).

v3: Add comment explaining why we do nothing in the sw_fence complete
callback (Michel).

Subject: drm/i915: More surgically unbreak the modeset vs reset deadlock

There's no reason to entirely wedge the gpu, for the minimal deadlock
bugfix we only need to unbreak/decouple the atomic commit from the gpu
reset. The simplest way to fix that is by replacing the
unconditional fence wait a the top of commit_tail by a wait which
completes either when the fences are done (normal case, or when a
reset doesn't need to touch the display state). Or when the gpu reset
needs to force-unblock all pending modeset states.

The lesser source of deadlocks is when we try to pin a new framebuffer
and run into a stall. There's a bunch of places this can happen, like
eviction, changing the caching mode, acquiring a fence on older
platforms. And we can't just break the depency loop and keep going,
the only way would be to break out and restart. But the problem with
that approach is that we must stall for the reset to complete before
we grab any locks, and with the atomic infrastructure that's a bit
tricky. The only place is the ioctl code, and we don't want to insert
code into e.g. the BUSY ioctl. Hence for that problem just create a
critical section, and if any code is in there, wedge the GPU. For the
steady-state this should never be a problem.

Note that in both cases TDR itself keeps working, so from a userspace
pov this trickery isn't observable. Users themselvs might spot a short
glitch while the rendering is catching up again, but that's still
better than pre-TDR where we've thrown away all the rendering,
including innocent batches. Also, this fixes the regression TDR
introduced of making gpu resets deadlock-prone when we do need to
touch the display.

One thing I noticed is that gpu_error.flags seems to use both our own
wait-queue in gpu_error.wait_queue, and the generic wait_on_bit
facilities. Not entirely sure why this inconsistency exists, I just
picked one style.

A possible future avenue could be to insert the gpu reset in-between
ongoing modeset changes, which would avoid the momentary glitch. But
that's a lot more work to implement in the atomic commit machinery,
and given that we only need this for pre-g4x hw, of questionable
utility just for the sake of polishing gpu reset even more on those
old boxes. It might be useful for other features though.

v2: Rebase onto 4.13 with a s/wait_queue_t/struct wait_queue_entry/.

v3: Really emabarrassing fixup, I checked the wrong bit and broke the
unbreak/wakeup logic.

v4: Also handle deadlocks in pin_to_display.

v5: Review from Michel:
- Fixup the BUILD_BUG_ON
- Don't forget about the overlay

Subject: soc: mediatek: add SCPSYS power domain driver for MediaTek MT7622 SoC

Add SCPSYS power domain driver for MT7622 SoC having four power domains
which are respectively ETHSYS for Ethernet including embedded switch,
WBSYS for WIFI and Bluetooth, HIF0SYS for PCI-E and SATA, and HIF1SYS for
USB. Those functions could be selectively powered gated when the
corresponding function is no longer to use in order to reach more minimal
power dissipation.

Subject: drm/i915: Perform an invalidate prior to executing golden renderstate

As we may have just bound the renderstate into the GGTT for execution, we
need to ensure that the GTT TLB are also flushed.

On snb-gt2, this would cause a random GPU hang at the start of a new
context (e.g. boot) and on snb-gt1, it was causing the renderstate batch
to take ~10s. It was the GPU hang that revealed the truth, as the CS
gleefully executed beyond the end of the golden renderstate batch, a good
indicator for a GTT TLB miss.

Subject: drm/i915/cnl: Add slice and subslice information to debugfs.

A missing part to EU slice power gating is the
debugfs interface. This patch actually should have been
squashed to the initial EU slice power gating one.

v2: Initial patch was merged without this part.

Fixes: c7ae7e9ab207 ("drm/i915/cnl: Configure EU slice power gating.")

Subject: drm/i915: Suppress switch_mm emission between the same aliasing_ppgtt

When switching between contexts using the aliasing_ppgtt, the VM is
shared. We don't need to reload the PD registers unless they are dirty.

Martin Peres reported an issue that looks like corruption between
Haswell context switches, bisecting to commit f9326be5f1d3 ("drm/i915:
Rearrange switch_context to load the aliasing ppgtt on first use").
Switching between the same mm (the aliasing_ppgtt is used for all
contexts in this case) should be a nop, but appears to trigger some
side-effects in the context switch. However, as we know the switch
is redundant in this case, we can skip it and continue to ignore the
issue until somebody feels strong enough to investigate full-ppgtt on
gen7 again!

Except.. Martin was using full-ppgtt which is not supported as it
doesn't work correctly yet. So whilst the bisect did yield valuable
information about the failures, the fix should not have any user impact
under default settings, with the exception of a slightly lower
throughput on xcs as the VM would always be reloaded.

v2: Also remember to set the legacy_active_context following the switch
on xcs (commit e8a9c58fcd9a ("drm/i915: Unify active context tracking
between legacy/execlists/guc"))

Subject: drm/i915: Avoid the gpu reset vs. modeset deadlock

... using the biggest hammer we have. This is essentially a weaponized
version of the timeout-based wedging Chris added in

commit 36703e79a982c8ce5a8e43833291f2719e92d0d1
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Thu Jun 22 11:56:25 2017 +0100

    drm/i915: Break modeset deadlocks on reset

Because defense-in-depth is good it's good to still have both. Also
note that with the locking change we can now restrict this a lot (old
gpus and special testing only), so this doesn't kill the TDR benefits
on at least anything remotely modern.

And futuremore with a few tricks it should be possible to make a much
more educated guess about whether an atomic commit is stuck waiting on
the gpu (atomic_t counting the pending i915_sw_fence used by the
atomic modeset code should do it), so we can improve this.

But for now just start with something that is guaranteed to recover
faster, for much better CI througput.

This defacto reverts TDR on these platforms, but there's not really a
single commit to specify as the sole offender.

v2: Add a debug message to explain what's going on. We can't DRM_ERROR
because that spams CI. And the timeout based fallback still prints a
DRM_ERROR, in case something goes wrong.

v3: Fix comment layout (Michel)

Subject: liquidio: update debug console logging mechanism

- remove logging dependency upon global func octeon_console_debug_enabled()
- abstract debug console logging using console structure (via function ptr)
  to allow for more flexible logging

There is no point in returning a value from function whose return value
is never checked.

Even if the return value was checked, there wouldn't be anything to do
about it, as these functions are either called from error or deletion
paths.

Subject: mlxsw: spectrum_router: Pass argument explicitly

Instead of relying on the LPM tree to be assigned to the virtual router
before binding the two, lets pass it explicitly.

This will later allow us to return upon binding error instead of having
to perform a rollback of the assignment.

Subject: mlxsw: spectrum_router: Use one LPM tree for all virtual routers

The number of LPM trees available for lookup is much smaller than the
number of virtual routers, which are used to implement VRFs. In
addition, an LPM tree can only be used by one protocol - either IPv4 or
IPv6.

Therefore, in order to increase the number of supported virtual routers
to the maximum we need to be able to share LPM trees across virtual
routers instead of trying to find an optimized tree for each.

Do that by allocating one LPM tree for each protocol, but make sure it
will only include prefixes that are actually used, so as to not perform
unnecessary lookups.

Since changing the structure of a bound tree isn't recommended, whenever
a new tree it required, it's first created and then bound to each
virtual router, replacing the old one.

Subject: i2c: designware: Fix system suspend

The commit 8503ff166504 ("i2c: designware: Avoid unnecessary resuming
during system suspend"), may suggest to the PM core to try out the so
called direct_complete path for system sleep. In this path, the PM core
treats a runtime suspended device as it's already in a proper low power
state for system sleep, which makes it skip calling the system sleep
callbacks for the device, except for the ->prepare() and the ->complete()
callbacks.

However, the PM core may unset the direct_complete flag for a parent
device, in case its child device are being system suspended before. In this
scenario, the PM core invokes the system sleep callbacks, no matter if the
device is runtime suspended or not.

Particularly in cases of an existing i2c slave device, the above path is
triggered, which breaks the assumption that the i2c device is always
runtime resumed whenever the dw_i2c_plat_suspend() is being called.

More precisely, dw_i2c_plat_suspend() calls clk_core_disable() and
clk_core_unprepare(), for an already disabled/unprepared clock, leading to
a splat in the log about clocks calls being wrongly balanced and breaking
system sleep.

To still allow the direct_complete path in cases when it's possible, but
also to keep the fix simple, let's runtime resume the i2c device in the
->suspend() callback, before continuing to put the device into low power
state.

Note, in cases when the i2c device is attached to the ACPI PM domain, this
problem doesn't occur, because ACPI's ->suspend() callback, assigned to
acpi_subsys_suspend(), already calls pm_runtime_resume() for the device.

It should also be noted that this change does not fix commit 8503ff166504
("i2c: designware: Avoid unnecessary resuming during system suspend").
Because for the non-ACPI case, the system sleep support was already broken
prior that point.

Subject: i2c: designware: Fix oops from i2c_dw_irq_handler_slave

When i2c-designware is initialized in slave mode the
i2c-designware-slave.c: i2c_dw_irq_handler_slave() can hit a NULL
pointer dereference when I2C slave backend is not registered but code is
accessing the struct dw_i2c_dev.slave without testing is it NULL.

We might get spurious interrupts from other devices or from IRQ core
during unloading the driver when CONFIG_DEBUG_SHIRQ is set. Existing
check for enable and IRQ status is not enough since device can be power
gated and those bits may read 1.

Fix this by handling the interrupt only when also struct dw_i2c_dev.slave
is set.

Subject: i2c: designware: Fix standard mode speed when configuring the slave
 mode

Code sets bit DW_IC_CON_SPEED_FAST (0x4) always when configuring the slave
mode. This results incorrect register value DW_IC_CON_SPEED_HIGH (0x6)
when OR'ed together with DW_IC_CON_SPEED_STD (0x2).

Remove this and let the code set the speed mode bits according to clock
frequency or default to fast mode.

Subject: i2c: core: Make comment about I2C table requirement to reflect the
 code

I2C drivers were required to have an I2C device ID table even if were for
devices that would only be registered using a specific firmware interface
(e.g: OF or ACPI).

But commit da10c06a044b ("i2c: Make I2C ID tables non-mandatory for DT'ed
devices") changed the I2C core to relax the requirement and allow drivers
to avoid defining this table.

Unfortunately it only took into account drivers for OF-only devices and
forgot about ACPI-only ones, and this was fixed by commit c64ffff7a9d1
("i2c: core: Allow empty id_table in ACPI case as well").

But the latter didn't update the original comment, so it doesn't reflect
what the code does now.

Subject: i2c: mv64xxx: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: i2c: aspeed: add proper support fo 24xx clock params

24xx BMCs have larger clock divider granularity which can cause problems
when trying to set them as 25xx clock dividers; this adds clock setting
code specific to 24xx.

This also fixes a potential issue where clock dividers were rounded down
instead of up.

Subject: leds: pca955x: add GPIO support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PCA955x family of chips are I2C LED blinkers whose pins not used
to control LEDs can be used as general purpose I/Os (GPIOs).

The following adds such a support by defining different operation
modes for the pins (See bindings documentation for more details). The
pca955x driver is then extended with a gpio_chip when some of pins are
operating as GPIOs. The default operating mode is to behave as a LED.

The GPIO support is conditioned by CONFIG_LEDS_PCA955X_GPIO.

Subject: platform/x86: ideapad-laptop: Expose conservation mode switch

This exposes the battery conservation mode present on some (?) IdeaPads.
The mode is set by calling ACPI method SBMC with argument 3 (on) or
5 (off). Status is reported in bit 5 of the return value of ACPI method
GBMD.

Subject: PCI/MSI: Assume MSIs use real Requester ID, not an alias

Currently, we handle all DMA aliases equally when calculating MSI requester
IDs for the generic infrastructure. This turns out to be the wrong thing to
do in the face of pure DMA quirks like those of Marvell SATA cards, where
in the usual case the last thing seen in the alias walk is the DMA phantom
function: we end up configuring the MSI doorbell to expect that alias, then
find we have no interrupts since the MSI writes still come from the 'real'
RID, thus get filtered out and ignored.

Improve the alias walk to only account for the topological aliases that
matter, based on the logic from the Intel IRQ remapping code.

Subject: drm/vc4: Continue the switch to drm_*_put() helpers

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

Generated by: scripts/coccinelle/api/drm-get-put.cocci

v2: Tweak commit summary to distinguish it from the previous commit
    covering everything but the new bo_label ioctl (by anholt).

Subject: staging: fsl-mc: add explicit dependencies for compile-tested arches

The driver makes use of GENERIC_MSI_IRQ_DOMAIN which requires arch
support so, on architectures that don't have it, the kernel will fail
to build. Add explicit dependency on architectures that were
compile-tested, thus fixing compilation for the ones that don't
implement GENERIC_MSI_IRQ_DOMAIN.

Putting a 900 byte array on the stack is a clearly too much in the
kernel, and sometimes results in warnings like:

drivers/staging/pi433/pi433_if.c:645:1: error: the frame size of 1028 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

This moves the buffer into the dynamically allocated per-device

Subject: drm/i915: Disconnect 32 and 48 bit ppGTT support

Configurations like virtualized environments may support only 48 bit
ppGTT without supporting 32 bit ppGTT. Support this by disconnecting
the relationship of the two feature bits.

Subject: drm/i915: Enable guest i915 full ppgtt functionality

Enable the guest i915 full ppgtt functionality when host can provide this
capability. vgt_caps is introduced to guest i915 driver to get the vgpu
capabilities from the device model. VGT_CPAS_FULL_PPGTT is one of the
capabilities type to let guest i915 dirver know that the guest i915 full
ppgtt is supported by device model.

Notice that the minor version of pvinfo isn't bumped because of this
vgt_caps introduction, due to older guest would be broken by simply
increasing the pvinfo version. Although the pvinfo minor version doesn't
increase, the compatibility won't be blocked. The compatibility is ensured
by checking the value of caps field in pvinfo. Zero means no full ppgtt
support and BIT(2) means this feature is provided.

Changes since v1:
- Use u32 instead of uint32_t (Joonas)
- Move VGT_CAPS_FULL_PPGTT introduction to this patch and use #define
  instead of enum (Joonas)
- Rewrite the vgpu full ppgtt capability checking logic. (Joonas)
- Some coding style refine. (Joonas)

Changes since v2:
- Divide the whole patch set into two separate patch series, with one
  patch in i915 side to check guest i915 full ppgtt capability and enable
  it when this capability is supported by the device model, and the other
  one in gvt side which fixs the blocking issue and enables the device
  model to provide the capability to guest. And this patch focuses on guest
  i915 side. (Joonas)
- Change the title from "introduce vgt_caps to pvinfo" to
  "Enable guest i915 full ppgtt functionality". (Tina)

Change since v3:
- Add some comments about pvinfo caps and version. (Joonas)

Change since v4:
- Tested by Tina Zhang.

Change since v5:
- Add limitation about supporting 32bit full ppgtt.

Change since v6:
- Change the fallback to 48bit full ppgtt if i915.ppgtt_enable=2. (Zhenyu)

Change in v9:
- Remove the fixme comment due to no plan for 32bit full ppgtt
  support. (Zhenyu)
- Reorder the patch-set to fix compiling issue with git-bisect. (Zhenyu)
- Add print log when forcing guest 48bit full ppgtt. (Zhenyu)

v10:
- Update against Joonas's has_full_ppgtt and has_full_48bit_ppgtt disconnect
  change. (Zhenyu)

Subject: drm/i915/gvt: Fix guest i915 full ppgtt blocking issue

Guest i915 full ppgtt functionality was blocking by an issue, which would
lead to gpu hardware hang. Guest i915 driver may update the ppgtt table
just before this workload is going to be submitted to the hardware by
device model. This case wasn't handled well by device model before, due
to the small time window between removing old ppgtt entry and adding the
new one. Errors occur when the workload is executed by hardware during
that small time window. This patch is to remove this time window by adding
the new ppgtt entry first and then remove the old one.

Changes in v2:
- Move VGT_CAPS_FULL_PPGTT introduction to patch 2/4. (Joonas)

Changes since v2:
- Divide the whole patch set into two separate patch series, with one
  patch in i915 side to check guest i915 full ppgtt capability and enable
  it when this capability is supported by the device model, and the other
  one in gvt side which fixs the blocking issue and enables the device
  model to provide the capability to guest. And this patch focuses on gvt
  side. (Joonas)
- Change the title from "reorder the shadow ppgtt update process by adding
  entry first" to "Fix guest i915 full ppgtt blocking issue". (Tina)

Changes since v3:
- Rebase to the latest branch.

Changes since v4:
- Tested by Tina Zhang.

Changes since v5:
- Rebase to the latest branch.

v6:
- Update full 48bit ppgtt definition

Subject: PCI: Disable PCIe Relaxed Ordering if unsupported

When bit4 is set in the PCIe Device Control register, it indicates
whether the device is permitted to use relaxed ordering.
On some platforms using relaxed ordering can have performance issues or
due to erratum can cause data-corruption. In such cases devices must avoid
using relaxed ordering.

The patch adds a new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING to indicate that
Relaxed Ordering (RO) attribute should not be used for Transaction Layer
Packets (TLP) targeted towards these affected root complexes.

This patch checks if there is any node in the hierarchy that indicates that
using relaxed ordering is not safe. In such cases the patch turns off the
relaxed ordering by clearing the capability for this device.

Subject: PCI: Disable Relaxed Ordering for some Intel processors

According to the Intel spec section 3.9.1 said:

    3.9.1 Optimizing PCIe Performance for Accesses Toward Coherent Memory
          and Toward MMIO Regions (P2P)

    In order to maximize performance for PCIe devices in the processors
    listed in Table 3-6 below, the soft- ware should determine whether the
    accesses are toward coherent memory (system memory) or toward MMIO
    regions (P2P access to other devices). If the access is toward MMIO
    region, then software can command HW to set the RO bit in the TLP
    header, as this would allow hardware to achieve maximum throughput for
    these types of accesses. For accesses toward coherent memory, software
    can command HW to clear the RO bit in the TLP header (no RO), as this
    would allow hardware to achieve maximum throughput for these types of
    accesses.

    Table 3-6. Intel Processor CPU RP Device IDs for Processors Optimizing
               PCIe Performance

    Processor                            CPU RP Device IDs

    Intel Xeon processors based on       6F01H-6F0EH
    Broadwell microarchitecture

    Intel Xeon processors based on       2F01H-2F0EH
    Haswell microarchitecture

It means some Intel processors has performance issue when use the Relaxed
Ordering Attribute, so disable Relaxed Ordering for these root port.

Subject: PCI: Disable Relaxed Ordering Attributes for AMD A1100

Casey reported that the AMD ARM A1100 SoC has a bug in its PCIe
Root Port where Upstream Transaction Layer Packets with the Relaxed
Ordering Attribute clear are allowed to bypass earlier TLPs with
Relaxed Ordering set, it would cause Data Corruption, so we need
to disable Relaxed Ordering Attribute when Upstream TLPs to the
Root Port.

Subject: net/cxgb4: Use new PCI_DEV_FLAGS_NO_RELAXED_ORDERING flag

cxgb4 Ethernet driver now queries PCIe configuration space to determine
if it can send TLPs to it with the Relaxed Ordering Attribute set.

Remove the enable_pcie_relaxed_ordering() to avoid enable PCIe Capability
Device Control[Relaxed Ordering Enable] at probe routine, to make sure
the driver will not send the Relaxed Ordering TLPs to the Root Complex which
could not deal the Relaxed Ordering TLPs.

Subject: mlxsw: spectrum_router: Prepare nexthop group's hash table for IPv6

This patch does preparation before introducing IPv6 nexthop group
consolidation. Currently the nexthop group hash table is used only by
IPv4 and uses fixed key size. In order to support the IPv6's variable
length key the current table is changed.

Subject: mlxsw: spectrum_router: Add support for nexthop group consolidation
 for IPv6

Due to limited ASIC resources the maximum number of routes is limited by
the nexthop resource. In order to improve the routing scale nexthop
consolidation should be performed.

This patch adds support for IPv6 neighbor consolidation. The hash value
is calculated based on the nexthop set, by performing bitwise xor on the
ifindexs of the nexthops, in a similar way to IPv4's kernel implementation.
In case of collision a full match is performed between the sets which
include address and ifindex comparison.

Non gateway nexthop groups are not inserted to the hash table due to
lack of nexthop device (ifindex).

Subject: liquidio: fix issues with fw_type module parameter

The fw_type module parameter isn't showing up in the
/sys/module/liquidio/parameters directory.  Fix it by setting the read
permission bits for user, group, other in module_param_string().  Revise
the description of fw_type.  Initialize the fw_type static char array with
the default value to conform to the module parameter description.

Subject: thermal: intel_pch_thermal: Fix enable check on Broadwell-DE

Using the TSDSS flag to determine whether the thermal sensor is
enabled is problematic. Broadwell-DE (Xeon D-1500) does not support
dynamic shutdown and the TSDSS flag always reads 0 (contrary to the
current datasheet). Even on hardware supporting dynamic shutdown, the
driver does nothing to configure it, and the dynamic shutdown state
should not prevent the driver from loading. The ETS flag itself
indicates whether the thermal sensor is enabled, so use it instead of
the TSDSS flag on all hardware platforms.

Subject: drm/i915/dp: Generalize intel_dp_link_params function to accept
 arguments to be validated

This function now takes the link rate and lane ocunt to be validated
as an argument so that this can be used for validating even the
compliance test link parameters.

Subject: drm/i915/dp: Validate the compliance test link parameters

Validate the compliance test link parameters when the compliance
test dpcd registers are read. Also validate them in compute_config
before using them since the max values might have been reduced
due to link training fallback.

If either the link rate or lane count is invalid, we still bail
from using the test parameters since the combination would not work
and instead use the fallback values.

v2:
* Added commit message to explain why we still bail when either of
of the params is invalid (Ville Syrjala)
* Add reason for validating in the comment (Jani Nikula)
* Also check if index >= 0 after validating (Jani Nikula)

Subject: drm/i915: Initialize 'data' in intel_dsi_dcs_backlight.c

variable 'data' may be used uninitialized in this function. thus,
'function dcs_get_backlight' will return unwanted value/fail.

Thus, adding NULL initialized to 'data' variable will solve the return
failure happening.

v2: Change commit message to reflect upstream with proper message

Subject: HID: input: throttle battery uevents

The power_supply subsystem tends to emit uevent every time
power_supply_changed() is called, so we should call this API only when battery
strength reported by the device is actually different from the previous
readings, otherwise we'll drown the system in uevents.

Subject: gpio: aspeed: Remove reference to clock name in debounce warning
 message

HPLL is in fact not the clock we need. Remove the description of which clock we
failed to find a phandle to in order to avoid any further error.

Subject: usb: mtu3: handle delayed status of the control transfer

Add the delayed status handling. This is used by mass storage etc to
gain some extra time to setup its internal status before it can proceed
further requests, and once the gadget is ready, it will enqueue an
empty packet which is used for synchronization.
The issue may happen on some FGPA platform with very low cpu frequency.

Subject: usb: gadget: dummy: fix infinite loop because of missing loop
 decrement

The while loop never terminates because the loop counter i is never
decremented. Fix this by decrementing i.

Subject: drm/atomic: If the atomic check fails, return its value first

The last part of drm_atomic_check_only is testing whether we need to
fail with -EINVAL when modeset is not allowed, but forgets to return
the value when atomic_check() fails first.

This results in -EDEADLK being replaced by -EINVAL, and the sanity
check in drm_modeset_drop_locks kicks in:

Solve this by adding the missing return.

This is also a bugfix because we could end up rejecting updates with
-EINVAL because of a early -EDEADLK, while if atomic_check ran to
completion it might have downgraded the modeset to a fastset.

Subject: usb: gadget: f_midi: Use snd_card_free_when_closed with refcount

Currenly, f_midi_free uses snd_card_free, which will wait
until the user has released the sound card before
returning. However, if the user doesn't release the sound
card, then f_midi_free can block for an arbitrary amount
of time, which also blocks any gadget operations on that
thread.

Instead, we can use snd_card_free_when_closed which returns
before all handles are released. Since f_midi can be
accessed through rmidi if usb_put_function is called before
release_card_device, add refcounting to f_midi_free and
have rawmidi's private free call it. The f_midi memory
is only kfreed when usb_put_function and release_card_device
have both been called.

Subject: usb: dwc3: of-simple: remove include of clk-provider.h

The header clk-provider.h is there for clock drivers (providers) to
include, not client drivers (consumers).  That said,
of_clk_get_parent_count() is a helper function for clock providers, not
a clk API for consumers.

Let's replace of_clk_get_parent_count() with of_count_phandle_with_args()
call, so that we can remove the include of clk-provider.h.

Subject: usb: gadget: core: unmap request from DMA only if previously mapped

In the SG case this is already handled since a non-zero
request->num_mapped_sgs is a clear indicator that dma_map_sg()
had been called. While it would be nice to do the same for the
singly mapped case by simply checking for non-zero request->dma,
it's conceivable that 0 is a valid dma_addr_t handle. Hence add
a flag 'dma_mapped' to struct usb_request and use this to
determine the need to call dma_unmap_single(). Otherwise, if a
request is not DMA mapped then the result of calling
usb_request_unmap_request() would safely be a no-op.

In the case hcd autosuspend is enabled, the hcd will enter L2 state
if no device connected. But if the controller works in otg mode, the
gadget driver still works in L0 state if connected with host. This
may result in transfer fail when gadget enqueue new request but the
hcd driver has set the global state into L2. This patch prevent the
hcd enter L2 state if the controller work in device mode.

Subject: usb: gadget: add RNDIS configfs options for class/subclass/protocol

This adds 3 new options to the RNDIS gadget function configs. It allows
overriding the default USB interface class/subclass/protocol.

The motivation for this is that if you set the values to "ef" (Misc),
"04" (RNDIS), "01" (Ethernet) respectively, then the device will be
recognized by the rndiscmp.inf file in Windows Vista and newer and will
cause Windows to load the correct RNDIS driver without the need for a
custom (signed) .inf file.

Subject: usb: bdc: Fix misleading register names

The BDC endpoint status registers 0-7 were originally each going
to be an array of regsiters. This was later changed to being a
single register. The register definitions are being changed from:
"#define BDC_EPSTS0(n)  (0x60 + (n * 0x10))"
to
"#define BDC_EPSTS0	0x60"
to reflect this change and to avoid future coding mistakes.

Subject: usb: bdc: Add support for suspend/resume

Based on a previous commit by Danesh Petigara <dpetigara@broadcom.com>
that added resume to solve the following problem:
"The BDC driver will fail after resuming from S3 suspend and this
will cause any upper layer gadget driver to fail."
This commit also adds support for suspend and manages the clock during
suspend/resume.

Subject: usb: bdc: fix "xsf for ep not enabled" errror

This patch essentially clears the port status change bits at the
correct times. It is necessary because the driver was not handling
the change bits correctly for events during device
connection/disconnection and bus enumeration. So, one of them (PCC)
was left stuck sometimes causing the "xsf for ep not enabled"
error we get on first connection. This was found by the Android team.
This was debugged and fixed by Sasi Kumar.

Subject: usb: gadget: f_fs: Pass along set_halt errors.

Users can apply i/o in the wrong direction on an
endpoint to stall it. In case there is an error
that does not allow the endpoint to be stalled,
we want the user to know.

An operation to stall the endpoint will return
EBADMSG if successful, EAGAIN if there are still
queued requests, and other errors depending on
the underlying implementation.

Also remove the conditional since it is always true.

Subject: drm/i915: Work around GCC anonymous union initialization bug

GCC 4.4 can't cope with anonymous union initializers which seems to be a
bug in that version (see the Reference) and is fixed since GCC version
4.6. A workaround which is also used elsewhere in the kernel for the
same purpose is to wrap the initialization in curly braces, so do the
same here.

Fixes: b5565a2efc12 ("drm/i915/bxt, glk: Give a proper name to the power well struct phy field")

From 2926a2aa5c14fb2add75e6584845b1c03022235f Mon Sep 17 00:00:00 2001
From: Joerg Roedel <jroedel@suse.de>
Date: Mon, 14 Aug 2017 17:19:26 +0200
Subject: iommu: Fix wrong freeing of iommu_device->dev

The struct iommu_device has a 'struct device' embedded into
it, not as a pointer, but the whole struct. In the
conversion of the iommu drivers to use struct iommu_device
it was forgotten that the relase function for that struct
device simply calls kfree() on the pointer.

This frees memory that was never allocated and causes memory
corruption.

To fix this issue, use a pointer to struct device instead of
embedding the whole struct. This needs some updates in the
iommu sysfs code as well as the Intel VT-d and AMD IOMMU
driver.

Reported-by: Sebastian Ott <sebott@linux.vnet.ibm.com>
Fixes: 39ab9555c241 ('iommu: Add sysfs bindings for struct iommu_device')

The function probes the PAMU hardware from device-tree
specifications. It initializes global variables and can thus
be only safely called once.

Add a check that that prints a warning when its called more
than once.

Subject: usb: phy: Add USB charger support

This patch introduces the usb charger support based on usb phy that
makes an enhancement to a power driver. The basic conception of the
usb charger is that, when one usb charger is added or removed by
reporting from the extcon device state change, the usb charger will
report to power user to set the current limitation.

Power user can register a notifiee on the usb phy by issuing
usb_register_notifier() to get notified by charger status changes
or charger current changes.

we can notify what current to be drawn to power user according to
different charger type, and now we have 2 methods to get charger type.
One is get charger type from extcon subsystem, which also means the
charger state changes. Another is we can get the charger type from
USB controller detecting or PMIC detecting, and the charger state
changes should be told by issuing usb_phy_set_charger_state().

Subject: power: wm831x_power: Support USB charger current limit management

Integrate with the newly added USB charger interface to limit the current
we draw from the USB input based on the input device configuration
identified by the USB stack, allowing us to charge more quickly from high
current inputs without drawing more current than specified from others.

Subject: ACPI: SPCR: extend XGENE 8250 workaround to m400

xgene v1/v2 chips are also used on moonshot cartridges that have
different table headers to the ones on Mustang. Extend the quirk
so it also recognises the Moonshot M400 variant too.

omap_framebuffer_create() fails to unref all the gem objects if creating
the FB fails, leading to a memory leak.

Fix the loop so that it goes through all the reffed gem objects.

Subject: drm/omap: Support for HDMI hot plug detection

The HPD signal can be used for detecting HDMI cable plug and unplug event
without the need for polling the status of the line.
This will speed up detecting such event because we do not need to wait for
the next poll event to notice the state change.

Subject: drm/omap: displays: connector-hdmi: Support for hot plug detection

If the hpd_gpio is valid, use interrupt handler to react to HPD changes.
In case the hpd_gpio is not valid, try to enable hpd detection on the
encoder if it supports it.

As non-DT booting is no longer supported, the only way to instantiate
the device is through an OF node, which is guaranteed to be present.
Remove the unneeded check.

Subject: drm: omapdrm: dpi: Remove unneeded regulator check

The dpi_display_enable() function ensures that a VDDS_DSI regulator is
available if the DSI uses the VDDS_DSI supply. This is not needed, as a
failure to get the VDDS_DSI supply will result in a probe failure,
dpi_display_enable() will thus never be called in that case.

Remove the check, and replace tests for the FEAT_DPI_USES_VDDS_DSI
feature with a test for the regulator object.

Subject: drm: omapdrm: hdmi: Store PHY features in PHY data structure

PHY features are stored in a global variable, while they should be
properties of the PHY object. As existing OMAP platforms have a single
HDMI PHY this doesn't cause any issue, but doesn't follow the driver
model.

Move the PHY features to the HDMI PHY data structure to follow the
driver model and pave the road for multiple HDMI PHYs support.

Subject: drm: omapdrm: dsi: Store DSI model and PLL hardware data in OF data

The DSI PLL hardware data and DSS channels are selected based on the
OMAP SoC model. There's no need for fine-grained model information, as
the driver only needs to differentiate between OMAP3, OMAP4 and OMAP5.
As this can be done through the DSI compatible string, store the
corresponding information in OF match data instead to avoid accessing
the OMAP SoC model.

Subject: drm: omapdrm: Don't forward set_min_bus_tput() to no-op platform code

The OMAP implementation of the set_min_bus_tput() API is a no-op.
There's no point in forwarding the driver calls to the platform code.
Remove the use of the related platform data callback, but keep the
internal function as a reminder that the feature will need to be
implemented when the OMAP platform will provide support.

Subject: drm: omapdrm: dispc: Select features based on compatible string

Use the compatible string instead of the OMAP SoC revision to determine
device features. On OMAP34xx the features depend on the ES revision that
can not be determined from the compatible string. Use soc_device_match()
in that case.

Subject: drm: omapdrm: dpi: Replace OMAP SoC model checks with DSS model

The DPI code only needs to differentiate between major OMAP revisions,
which can be obtained from the DSS compatible string. Replace the OMAP
SoC model checks to prepare for removal of the OMAP SoC version platform
data.

Subject: drm: omapdrm: dss: Use supported outputs instead of display types

The dss driver uses the supported display types to check whether the DSS
has SDI, VENC or HDMI outputs. We can instead use the supported outputs
the provide the same information. This removes the last use of the
supported display types, that we can then remove as well.

Subject: drm: omapdrm: dss: Initialize DSS internal features at probe time

The DSS internal features are derived from the platform device
compatible string which is available at probe time. Don't delay
initialization until bind time. This prepares for the merge of the two
DSS features structures that will be needed before the DSS is bound.

Subject: drm: omapdrm: Move num_ovls and num_mgrs to dispc_features structure

The num_ovls and num_mgrs are dispc features. Move them from the
omap_dss_features structure to the dispc_features structure.

From 51919572c89a0c5dcf0cfff4ba4b36e175f091c7 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Sat, 5 Aug 2017 01:44:18 +0300
Subject: drm: omapdrm: Move supported outputs feature to dss driver

The supported outputs feature is specific to the DSS, move it from the
omap_dss_features structure to the dss driver.

The omap_dss_features structure is now empty and can be removed.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Sat, 5 Aug 2017 01:44:19 +0300
Subject: drm: omapdrm: Remove dss_features.h

The header file only contains four macros, two of which are never used.
Move the other two to dss.h and remove dss_features.h.

Subject: drm/i915/hsw+: Add support for multiple power well regs

Future platforms increase the number of power wells which require
additional control registers. A convenient way to select the correct
register is to use the high bits of the power well ID as index. This
patch only prepares for this, while upcoming platform enabling patches
will add the actual new power well IDs and corresponding power well
control registers.

The stub functions returns -ENODEV when trying to register the cooling device,
thus failing the GPU bind, rendering the GPU subsystem unusable when
CONFIG_THERMAL isn't enabled.

Subject: xen: fix bio vec merging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current test for bio vec merging is not fully accurate and can be
tricked into merging bios when certain grant combinations are used.
The result of these malicious bio merges is a bio that extends past
the memory page used by any of the originating bios.

Take into account the following scenario, where a guest creates two
grant references that point to the same mfn, ie: grant 1 -> mfn A,
grant 2 -> mfn A.

These references are then used in a PV block request, and mapped by
the backend domain, thus obtaining two different pfns that point to
the same mfn, pfn B -> mfn A, pfn C -> mfn A.

If those grants happen to be used in two consecutive sectors of a disk
IO operation becoming two different bios in the backend domain, the
checks in xen_biovec_phys_mergeable will succeed, because bfn1 == bfn2
(they both point to the same mfn). However due to the bio merging,
the backend domain will end up with a bio that expands past mfn A into
mfn A + 1.

Fix this by making sure the check in xen_biovec_phys_mergeable takes
into account the offset and the length of the bio, this basically
replicates whats done in __BIOVEC_PHYS_MERGEABLE using mfns (bus
addresses). While there also remove the usage of
__BIOVEC_PHYS_MERGEABLE, since that's already checked by the callers
of xen_biovec_phys_mergeable.

Subject: xen-blkfront: use a right index when checking requests

Since commit d05d7f40791c ("Merge branch 'for-4.8/core' of
git://git.kernel.dk/linux-block") and 3fc9d690936f ("Merge branch
'for-4.8/drivers' of git://git.kernel.dk/linux-block"), blkfront_resume()
has been using an index for iterating ring_info to check request when
iterating blk_shadow in an inner loop. This seems to have been
accidentally introduced during the massive rewrite of the block layer
macros in the commits.

This may cause crash like this:

Subject: drm/i915: Split obj->cache_coherent to track r/w

Another month, another story in the cache coherency saga. This time, we
come to the realisation that i915_gem_object_is_coherent() has been
reporting whether we can read from the target without requiring a cache
invalidate; but we were using it in places for testing whether we could
write into the object without requiring a cache flush. So split the
tracking into two, one to decide before reads, one after writes.

See commit e27ab73d17ef ("drm/i915: Mark CPU cache as dirty on every
transition for CPU writes") for the previous entry in this saga.

v2: Be verbose
v3: Remove unused function (i915_gem_object_is_coherent)
v4: Fix inverted coherency check prior to execbuf (from v2)
v5: Add comment for nasty code where we are optimising on gcc's behalf.

Subject: hwmon: (aspeed-pwm) add THERMAL dependency

With CONFIG_THERMAL=m, a built-in aspeed pwm tacho driver causes
a link error:

drivers/hwmon/aspeed-pwm-tacho.o: In function `aspeed_pwm_tacho_probe':
aspeed-pwm-tacho.c:(.text+0x7f0): undefined reference to `thermal_of_cooling_device_register'

This adds a dependency similar to what other hwmon drivers use,
ensuring that the aspeed driver cannot be built-in in this
case but has to be a module. With THERMAL=n, we still allow building it.

Subject: drm/i915: Handle full s64 precision for wait-ioctl

The wait-ioctl is optionally supplied a timeout with nanosecond
precision in a s64 field. We use nsecs_to_jiffies64() to convert that
into the jiffies consumed by the scheduler, but internally
nsecs_to_jiffies64() does not guard against overflow (as it's purpose is
for use by the scheduler and not drivers!). So we must guard against the
overflow ourselves, and in the process note that we may then return
much earlier than the timeout selected by the user, so don't report
ETIME unless we do hit the timeout. (Woe betold us though if the user
waits for a year (32bit) and the request is still not complete!)

v2: Refine overflow detection (to not include an overffow itself)

From 0ae349a0f33fb040a2bc228fdc6d60111455feab Mon Sep 17 00:00:00 2001
From: Rob Clark <robdclark@gmail.com>
Date: Wed, 9 Aug 2017 10:43:04 -0400
Subject: iommu/qcom: Add qcom_iommu

An iommu driver for Qualcomm "B" family devices which do implement the
ARM SMMU spec, but not in a way that is compatible with how the arm-smmu
driver is designed.  It seems SMMU_SCR1.GASRAE=1 so the global register
space is not accessible.  This means it needs to get configuration from
devicetree instead of setting it up dynamically.

In the end, other than register definitions, there is not much code to
share with arm-smmu (other than what has already been refactored out
into the pgtable helpers).

Subject: drm/i915: Add support for drm syncobjs

This commit adds support for waiting on or signaling DRM syncobjs as
part of execbuf.  It does so by hijacking the currently unused cliprects
pointer to instead point to an array of i915_gem_exec_fence structs
which containe a DRM syncobj and a flags parameter which specifies
whether to wait on it or to signal it.  This implementation
theoretically allows for both flags to be set in which case it waits on
the dma_fence that was in the syncobj and then immediately replaces it
with the dma_fence from the current execbuf.

v2:
 - Rebase on new syncobj API
v3:
 - Pull everything out into helpers
 - Do all allocation in gem_execbuffer2
 - Pack the flags in the bottom 2 bits of the drm_syncobj*
v4:
 - Prevent a potential race on syncobj->fence

Testcase: igt/gem_exec_fence/syncobj*

Subject: iommu/amd: Add function copy_dev_tables()

Add function copy_dev_tables to copy the old DEV table entries of the panicked
kernel to the new allocated device table. Since all iommus share the same device
table the copy only need be done one time. Here add a new global old_dev_tbl_cpy
to point to the newly allocated device table which the content of old device
table will be copied to. Besides, we also need to:

  - Check whether all IOMMUs actually use the same device table with the same size

  - Verify that the size of the old device table is the expected size.

  - Reserve the old domain id occupied in 1st kernel to avoid touching the old
    io-page tables. Then on-flight DMA can continue looking it up.

And also define MACRO DEV_DOMID_MASK to replace magic number 0xffffULL, it can be
reused in copy_dev_tables().

Subject: iommu/amd: Copy old trans table from old kernel

Here several things need be done:
- If iommu is pre-enabled in a normal kernel, just disable it and print
  warning.

- If any one of IOMMUs is not pre-enabled in kdump kernel, just continue
  as it does in normal kernel.

- If failed to copy dev table of old kernel, continue to proceed as
  it does in normal kernel.

- Only if all IOMMUs are pre-enabled and copy dev table is done well, free
  the dev table allocated in early_amd_iommu_init() and make amd_iommu_dev_table
  point to the copied one.

- Disable and Re-enable event/cmd buffer,  install the copied DTE table
  to reg, and detect and enable guest vapic.

- Flush all caches

 old dev table entry

Firstly split the dev table entry copy into address translation part
and irq remapping part. Because these two parts could be enabled
independently.

Secondly do sanity check for address translation and irq remap of old
dev table entry separately.

Subject: iommu/amd: Allocate memory below 4G for dev table if translation
 pre-enabled

AMD pointed out it's unsafe to update the device-table while iommu
is enabled. It turns out that device-table pointer update is split
up into two 32bit writes in the IOMMU hardware. So updating it while
the IOMMU is enabled could have some nasty side effects.

The safe way to work around this is to always allocate the device-table
below 4G, including the old device-table in normal kernel and the
device-table used for copying the content of the old device-table in kdump
kernel. Meanwhile we need check if the address of old device-table is
above 4G because it might has been touched accidentally in corrupted
1st kernel.

Subject: iommu/amd: Don't copy GCR3 table root pointer

When iommu is pre_enabled in kdump kernel, if a device is set up with
guest translations (DTE.GV=1), then don't copy GCR3 table root pointer
but move the device over to an empty guest-cr3 table and handle the
faults in the PPR log (which answer them with INVALID). After all these
PPR faults are recoverable for the device and we should not allow the
device to change old-kernels data when we don't have to.

Subject: iommu/amd: Disable iommu only if amd_iommu=off is specified

It's ok to disable iommu early in normal kernel or in kdump kernel when
amd_iommu=off is specified. While we should not disable it in kdump kernel
when on-flight dma is still on-going.

From da4b02750a9fe1d1c4d047d14e69ec7542dddeb3 Mon Sep 17 00:00:00 2001
From: Robin Murphy <robin.murphy@arm.com>
Date: Fri, 4 Aug 2017 17:29:06 +0100
Subject: iommu/of: Fix of_iommu_configure() for disabled IOMMUs

Sudeep reports that the logic got slightly broken when a PCI iommu-map
entry targets an IOMMU marked as disabled in DT, since of_pci_map_rid()
succeeds in following a phandle, and of_iommu_xlate() doesn't return an
error value, but we miss checking whether ops was actually non-NULL.
Whilst this could be solved with a point fix in of_pci_iommu_init(), it
suggests that all the juggling of ERR_PTR values through the ops pointer
is proving rather too complicated for its own good, so let's instead
simplify the whole flow (with a side-effect of eliminating the cause of
the bug).

The fact that we now rely on iommu_fwspec means that we no longer need
to pass around an iommu_ops pointer at all - we can simply propagate a
regular int return value until we know whether we have a viable IOMMU,
then retrieve the ops from the fwspec if and when we actually need them.
This makes everything a bit more uniform and certainly easier to follow.

Subject: iommu/iova: Add flush-queue data structures

This patch adds the basic data-structures to implement
flush-queues in the generic IOVA code. It also adds the
initialization and destroy routines for these data
structures.

The initialization routine is designed so that the use of
this feature is optional for the users of IOVA code.

From: Joerg Roedel <jroedel@suse.de>
Date: Thu, 10 Aug 2017 16:14:59 +0200
Subject: iommu/iova: Add flush counters to Flush-Queue implementation

There are two counters:

	* fq_flush_start_cnt  - Increased when a TLB flush
	                        is started.

	* fq_flush_finish_cnt - Increased when a TLB flush
				is finished.

The fq_flush_start_cnt is assigned to every Flush-Queue
entry on its creation. When freeing entries from the
Flush-Queue, the value in the entry is compared to the
fq_flush_finish_cnt. The entry can only be freed when its
value is less than the value of fq_flush_finish_cnt.

The reason for these counters it to take advantage of IOMMU
TLB flushes that happened on other CPUs. These already
flushed the TLB for Flush-Queue entries on other CPUs so
that they can already be freed without flushing the TLB
again.

This makes it less likely that the Flush-Queue is full and
saves IOMMU TLB flushes.

Subject: iommu/iova: Add locking to Flush-Queues

The lock is taken from the same CPU most of the time. But
having it allows to flush the queue also from another CPU if
necessary.

This will be used by a timer to regularily flush any pending
IOVAs from the Flush-Queues.

Subject: iommu/vt-d: Allow to flush more than 4GB of device TLBs

The shift qi_flush_dev_iotlb() is done on an int, which
limits the mask to 32 bits. Make the mask 64 bits wide so
that more than 4GB of address range can be flushed at once.

Subject: libnvdimm, pfn, dax: limit namespace alignments to the supported set

Now that we properly advertise the supported pte, pmd, and pud sizes,
restrict the supported alignments that can be set on a namespace. This
assumes that userspace was not previously relying on the ability to set
odd alignments. At least ndctl only ever supported setting the namespace
alignment to 4K, 2M, or 1G.

Subject: efi/arm64: add EFI_KIMG_ALIGN

The EFI stub is intimately coupled with the kernel, and takes advantage
of this by relocating the kernel at a weaker alignment than the
documented boot protocol mandates.

However, it does so by assuming it can align the kernel to the segment
alignment, and assumes that this is 64K. In subsequent patches, we'll
have to consider other details to determine this de-facto alignment
constraint.

This patch adds a new EFI_KIMG_ALIGN definition that will track the
kernel's de-facto alignment requirements. Subsequent patches will modify
this as required.

Subject: s390/qeth: don't access skb after transmission

After transmitting a skb via send_packet[_fast](), the statistics
code accesses the skb once more to account for transmitted page frags.
This has a (theoretical?) race against the TX completion - if the TX
completion is processed and frees the skb before hard_start_xmit()
gets to the statistics part, we access random memory.

Fix this by caching the # of page frags, before the skb is transmitted.

qeth_l2_request_initial_mac() queries the device for its supported
adapterparms, even though they already have been queried as part of the
device's high-level setup. Remove that extra call.

The only call chain for qeth_l2_request_initial_mac() is
__qeth_l2_set_online()
	qeth_core_hardsetup_card()
		qeth_query_setadapterparms()
	qeth_l2_setup_netdev()
		qeth_l2_request_initial_mac()
			qeth_query_setadapterparms()

, and we only reach qeth_l2_request_initial_mac() if the first
adapterparms query succeeds. Hence removing the second query results in
no loss of functionality.

Subject: s390/qeth: clean up fill_buffer() offset logic

For some xmit paths we pass down a data offset to qeth_fill_buffer(),
to indicate that the first k bytes of the skb should be skipped when
mapping it into buffer elements.
Commit acd9776b5c45 ("s390/qeth: no ETH header for outbound AF_IUCV")
recently switched the offset for the IUCV-over-HiperSockets path
from 0 to ETH_HLEN, and now we have

	device	offset
	OSA	= 0
	IQD	> 0

for all xmit paths.

OSA would previously pass down -1 from do_send_packet(), to distinguish
between 1) OSA and 2) IQD with offset 0. That's no longer needed now,
so have it pass 0, make the offset unsigned and clean up how we apply
the offset in __qeth_fill_buffer().

No change of behaviour for any of our current xmit paths.

Subject: s390/qeth: make more use of skb API

Replace some open-coded parts with their proper API calls.

Also remove two skb_[re]set_mac_header() calls in the L2
xmit paths that are clearly no longer required, since at least
commit 6d1ccff62780 ("net: reset mac header in dev_start_xmit()").

Subject: s390/qeth: reject multicast rxip addresses

There exist different commands to add unicast and multicast addresses on
the OSA card. rxip addresses are always set as unicast addresses and
thus just unicast addresses should be allowed.

Adding a multicast address now fails and a grace message is generated.

Subject: s390/qeth: fix using of ref counter for rxip addresses

IP-address setting and removal are delayed when the device is not yet in
state SOFTSETUP or UP. ref_counter has been implemented only for
ip-address with type normal. In this patch ref_counter logic is also used
for ip-address with type rxip to allow appropriate handling of multiple
postponed rxip add and del calls.

Subject: drm/amdgpu: Add a parameter to amdgpu_bo_create()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The parameter init_value contains the value to which we initialized
VRAM bo when AMDGPU_GEM_CREATE_VRAM_CLEARED flag is set.

Subject: drm/amdgpu: Support IOMMU on Raven
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We achieved that by setting S(SYSTEM) and P(PDE as PTE) bit to 1 for
PDEs and setting S bit to 1 for PTEs when the corresponding addresses
are not occupied by gpu driver allocated buffers.

Subject: drm/amdgpu: Fix KFD initialization for multi-GPU systems

kfd2kgd is device-specific, so it should not be a global variable.
Merge amdgpu_amdkfd_load_interface and amdgpu_amdkfd_device_probe
so that it's only needed as a local variable in one function.

Subject: drm/amdgpu: Fix undue fallthroughs in golden registers initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan
initialization. However there is no comment stating that this is
intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

There are no external users of function radeon_atif_handler so it can
be static.

Subject: drm/amdgpu: switch to drm_*{get,put} helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to use
the new APIs.

Subject: drm/radeon: switch to drm_*{get,put} helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() adn should not be
used by new code. So convert all users of compatibility functions to use
the new APIs.

Subject: drm/amdgpu: don't finish the ring if not initialized
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If a ring is not initialized, it also should not be finished.
For example, in Vega10's SR-IOV environment, UVD's decode ring is not
initialized, but will be finnished in amdgpu_uvd_sw_fini, because UVD
driver put all the uvd decode ring's finish operation into
amdgpu_uvd_sw_fini function, while not uvd_vXXX_0_sw_fini. This will
lead to amdgpu module unloading failure.

MIME-Version: 1.0

My static checker complains that it's possible for "r" to be
uninitialized.  It used to be set to zero so this returns it to the old
behavior.

Subject: drm/amd/amdgpu: Added a quirk for Stoney platform

Added DW_I2S_QUIRK_16BIT_IDX_OVERRIDE quirk for Stoney.

Supported format and bus width for I2S controller read
from I2S Component Parameter registers.
These are ready only registers.

For Stoney, I2S Component Parameter registers are programmed
to support 32 bit format and 4 bytes bus width only.

By setting this quirk,It will override 32 bit format with
16 bit format and 2 bytes as bus width for Stoney.

Was using the wrong prefix (gmc rather than gfx).  The function
is related to the gfx hw, not gmc.  This also makes it consistent
with the naming in gfx8.

Subject: PCI: pciehp: Report power fault only once until we clear it

When a power fault occurs, the power controller sets Power Fault Detected
in the Slot Status register, and pciehp_isr() queues an INT_POWER_FAULT
event to handle it.

It also clears Power Fault Detected, but since nothing has yet changed to
correct the power fault, the power controller will likely set it again
immediately, which may cause an infinite loop when pcie_isr() rechecks
Slot Status.

Fix that by masking off Power Fault Detected from new events if the driver
hasn't seen the power fault clear from the previous handling attempt.

Subject: loop: fix to a race condition due to the early registration of device

The early device registration made possible a race leading to allocations
of disks with wrong minors.

This patch moves the device registration further down the loop_init
function to make the race infeasible.

Found by Linux Driver Verification project (linuxtesting.org).

Subject: lkdtm: Add -fstack-protector-strong test

There wasn't an LKDTM test to distinguish between -fstack-protector and
-fstack-protector-strong in use. This adds CORRUPT_STACK_STRONG to see
the difference. Also adjusts the stack-clobber value to 0xff so execution
won't potentially jump into userspace when the stack protector is missing.

Subject: PCI: rcar: Fix error exit path

Commit 90634e854079 ("PCI: rcar: Convert PCI scan API to
pci_scan_root_bus_bridge()") converted PCI root bus scan API to the new
pci_scan_root_bus_bridge() API; in the process some error paths were not
updated correctly which may cause memory leaks.

Fix the driver error exit path reinstating the previous correct
error exit behaviour.

Subject: drm/i915/edp: Allow alternate fixed mode for eDP if available.

Some fixed resolution panels actually support more than one mode,
with the only thing different being the refresh rate.  Having this
alternate mode available to us is desirable, because it allows us to
test PSR on panels whose setup time at the preferred mode is too long.
With this patch we allow the use of the alternate mode if it's
available and it was specifically requested.

v2 and v3: Rebase
v4: * Fix up some leaky mode stuff (Chris)
    * Rebase
v5: * Fix a NULL pointer derefrence (David Weinehall)
v6: * Whitespace / spelling / checkpatch clean-up; no functional
      change. (David)
    * Rebase

Subject: ipv6: fib: Provide offload indication using nexthop flags

IPv6 routes currently lack nexthop flags as in IPv4. This has several
implications.

In the forwarding path, it requires us to check the carrier state of the
nexthop device and potentially ignore a linkdown route, instead of
checking for RTNH_F_LINKDOWN.

It also requires capable drivers to use the user facing IPv6-specific
route flags to provide offload indication, instead of using the nexthop
flags as in IPv4.

Add nexthop flags to IPv6 routes in the 40 bytes hole and use it to
provide offload indication instead of the RTF_OFFLOAD flag, which is
removed while it's still not part of any official kernel release.

In the near future we would like to use the field for the
RTNH_F_{LINKDOWN,DEAD} flags, but this change is more involved and might
not be ready in time for the current cycle.

Subject: mlxsw: spectrum_router: Use correct config option

I made an embarrassing mistake and used 'IPV6' instead of 'CONFIG_IPV6'
around the function that updates the kernel about IPv6 neighbours
activity. This can be a problem if the kernel has more neighbours than a
certain threshold and it starts deleting those that are supposedly
inactive.

Subject: sfc: don't try and read ef10 data on non-ef10 NIC

The MAC stats command takes a port ID, which doesn't exist on
pre-ef10 NICs (5000- and 6000- series). This is extracted from the
NIC specific data; we misinterpret this as the ef10 data structure,
causing us to read potentially unallocated data. With a KASAN kernel
this can cause errors with:

====================== cut here =============================

It looks like the pci_find_pcie_root_port() was trying to
find the Root Port for the PCI device which is the Root
Port already, it will return NULL and trigger the problem,
so check the highest_pcie_bridge to fix thie problem.

Fixes: a99b646afa8a ("PCI: Disable PCIe Relaxed Ordering if unsupported")
Fixes: c56d4450eb68 ("PCI: Turn off Request Attributes to avoid Chelsio T5 Completion erratum")

Subject: extcon: Correct description to improve the readability

The extcon files explains the detailed operation for functions and
what is meaning of extcon structure. There are different explanation
even if the same argument.

So, it modifies the description for both functions and structures
in order to improve the readability and guide the role of functions
more well.

Also, this patch fixes the mismatching license info as a GPL v2
and removes the inactive author information.

From efa479352fc780b305fa186cafb5f416fdf2b2cb Mon Sep 17 00:00:00 2001
From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Tue, 15 Aug 2017 10:52:50 +0200
Subject: drm/nouveau: Fix merge commit

The most recent merge commit in airlied/drm-next has problems with
confusing old_crtc_state and new_crtc_state. Use the
for_each_oldnew_crtc_in_state macros to clean up the confusion,
and explicitly look at the correct state instead of looking at
asyh->state.

With these fixes it becomes more obvious what the code is trying to do,
which will hopefully prevent future confusion.

Subject: drm/amdkfd: Clean up KFD style errors and warnings v2

Using checkpatch.pl -f <file> showed a number of style issues. This
patch addresses as many of them as possible. Some long lines have been
left for readability, but attempts to minimize them have been made.

v2: Broke long lines in gfx_v7 get_fw_version

From 79775b627dc49df06880a32b4340674554c669b9 Mon Sep 17 00:00:00 2001
From: Kent Russell <kent.russell@amd.com>
Date: Tue, 15 Aug 2017 23:00:05 -0400
Subject: drm/amdkfd: Consolidate and clean up log commands

Consolidate log commands so that dev_info(NULL, "Error...") uses the more
accurate pr_err, remove the module name from the log (can be seen via
dynamic debugging with +m), and the function name (can be seen via
dynamic debugging with +f). We also don't need debug messages saying
what function we're in. Those can be added by devs when needed

Don't print vendor and device ID in error messages. They are typically
the same for all GPUs in a multi-GPU system. So this doesn't add any
value to the message.

Lastly, remove parentheses around %d, %i and 0x%llX.
According to kernel.org:
"Printing numbers in parentheses (%d) adds no value and should be
avoided."

From 4eacc26b3b99c32deed150adff5e38ebce60527c Mon Sep 17 00:00:00 2001
From: Kent Russell <kent.russell@amd.com>
Date: Tue, 15 Aug 2017 23:00:06 -0400
Subject: drm/amdkfd: Change x==NULL/false references to !x

Upstream prefers the !x notation to x==NULL or x==false. Along those lines
change the ==true or !=NULL references as well. Also make the references
to !x the same, excluding () for readability.

From ab7c16486707f86264c73b043327c70866236722 Mon Sep 17 00:00:00 2001
From: Kent Russell <kent.russell@amd.com>
Date: Tue, 15 Aug 2017 23:00:07 -0400
Subject: drm/amdkfd: Fix goto usage v2

Remove gotos that do not feature any common cleanup, and use gotos
instead of repeating cleanup commands.

According to kernel.org: "The goto statement comes in handy when a
function exits from multiple locations and some common work such as
cleanup has to be done. If there is no cleanup needed then just return
directly."

v2: Applied review suggestions in create_queue_nocpsch

Subject: drm/amdkfd: Remove usage of alloc(sizeof(struct...

See https://kernel.org/doc/html/latest/process/coding-style.html
under "14) Allocating Memory" for rationale behind removing the
x=alloc(sizeof(struct) style and using x=alloc(sizeof(*x) instead

From 4f52f2256eae0b8495c308b78a7edf4094e3dd67 Mon Sep 17 00:00:00 2001

Subject: drm/amdkfd: Remove BUG_ONs for NULL pointer arguments

Remove BUG_ONs that check for NULL pointer arguments that are
dereferenced in the same function. Dereferencing the NULL pointer
will generate a BUG anyway, so the explicit check is redundant and
unnecessary overhead.

Subject: drm/amdkfd: Allocate gtt_sa_bitmap in long units

gtt_sa_bitmap is accessed by bitmap functions, which operate on longs.
Therefore the array should be allocated in long units. Also round up
in case the number of bits is not a multiple of BITS_PER_LONG.

Subject: drm/amdkfd: Handle remaining BUG_ONs more gracefully v2

In most cases, BUG_ONs can be replaced with WARN_ON with an error
return. In some void functions just turn them into a WARN_ON and
possibly an early exit.

v2:
* Cleaned up error handling in pm_send_unmap_queue
* Removed redundant WARN_ON in kfd_process_destroy_delayed

Subject: drm/amdkfd: Clamp EOP queue size correctly on Gfx8

Gfx8 HW incorrectly clamps CP_HQD_EOP_CONTROL.EOP_SIZE, which can
lead to scheduling deadlock due to SE EOP done counter overflow.

Enforce a EOP queue size limit which prevents the CP from sending
more than 0xFF events at a time.

Subject: drm/amdkfd: Update PM4 packet headers

To match current firmware. The map process packet has been extended
to support scratch. This is a non-backwards compatible change and
it's about two years old. So no point keeping the old version around
conditionally.

Subject: drm/amdgpu: Add kgd/kfd interface to support scratch memory v2

v2:
* Shortened headline
* Removed write_config_static_mem, it gets initialized by gfx_v?_0_gpu_init
* Renamed alloc_memory_of_scratch to set_scratch_backing_va
* Made set_scratch_backing_va a void function
* Documented set_scratch_backing in kgd_kfd_interface.h

Subject: sparc64: vcc: Enable VCC port probe and removal

Enables VCC port probe and removal to initialize and terminate
VCC ports respectively. When a device/port matching the VCC driver
is added, the probe function is invoked along with a reference
to the device. remove function is called when the device is
removed.

Also add APIs to cache and retrieve VCC ports from a VCC table

Subject: parisc: pci memory bar assignment fails with 64bit kernels on
 dino/cujo

For 64bit kernels the lmmio_space_offset of the host bridge window
isn't set correctly on systems with dino/cujo PCI host bridges.
This leads to not assigned memory bars and failing drivers, which
need to use these bars.

Subject: clk: renesas: rcar-gen3: Add divider support for PLL1 and PLL3

On some R-Car Gen3 SoCs (e.g. R-Car D3), PLL1 and PLL3 use a divider
value different from one.  Extend struct rcar_gen3_cpg_pll_config to handle
this.  As all multipliers and dividers are small, table size increase
can be kept limited by storing them in u8s instead of unsigned ints,
which saves ca. 0.5 KiB for a generic kernel.

Subject: clk: renesas: rcar-gen3: Add support for SCCG/Clean peripheral clocks

On R-Car Gen3 SoCs with a Spread Spectrum Clock Generator (e.g. R-Car
D3), a peripheral clock divider has been added, to select between clean
and spread spectrum parents.

Add a new clock type to the R-Car Gen3 driver core to handle this.
To avoid increasing the size of struct cpg_core_clk, both parents and
dividers are stored in the existing parent resp. div fields.

Subject: nvmet: don't overwrite identify sn/fr with 0-bytes

The merged version of my patch "nvmet: don't report 0-bytes in serial
number" fails to remove two lines which should have been replaced,
so that the space-padded strings are overwritten again with 0-bytes.
Fix it.

Subject: Bluetooth: btusb: driver to enable the usb-wakeup feature

BT-Controller connected as platform non-root-hub device and
usb-driver initialize such device with wakeup disabled,
Ref. usb_new_device().

At present wakeup-capability get enabled by hid-input device from usb
function driver(e.g. BT HID device) at runtime. Again some functional
driver does not set usb-wakeup capability(e.g LE HID device implement
as HID-over-GATT), and can't wakeup the host on USB.

Most of the device operation (such as mass storage) initiated from host
(except HID) and USB wakeup aligned with host resume procedure. For BT
device, usb-wakeup capability need to enable form btusc driver as a
generic solution for multiple profile use case and required for USB remote
wakeup (in-bus wakeup) while host is suspended. Also usb-wakeup feature
need to enable/disable with HCI interface up and down.

Subject: drm/omap: add OMAP5 DSIPHY lane-enable support

We are missing OMAP5 DSIPHY lane-enable support, which has prevented
OMAP5 DSI working in mainline. This patch adds the lane-enable similarly
to the recently added OMAP4 version.

Subject: drm: omapdrm: hdmi: Rename functions and structures to use hdmi_

The dsi_pll_ops structure and dsi_init_pll_data() function incorrectly
use a dsi_ prefix, likely due to copy & paste. Fix it by using the
correct hdmi_ prefix.

Subject: drm: omapdrm: hdmi: Don't allocate PHY features dynamically

There's no need to allocate memory dynamically to duplicate the contents
of a const structure, only to store the memory pointer in a const
pointer field. Just use the original structures directly.

Subject: spi: altera: Switch to SPI core transfer queue management

The Altera SPI driver currently uses the spi-bitbang infrastructure for
transfer queue management, but non of the bitbang functionality itself.
This is because when the driver was written this was the only way to not
have to do queue management in the driver itself.

Nowadays transfer queue management is available from the SPI driver core
itself and using the bitbang infrastructure just adds an additional level
of indirection.

Switch the driver over to using the core queue management directly.

Subject: pinctrl: sh-pfc: r8a7795: Fix MOD_SEL2 bit26 to 0x0 when using SCK5_A

This patch fixes the implementation incorrect of MOD_SEL2 bit26 value
when SCK5_A pin function is selected for IPSR16 bit[31:28].

This is a correction to the incorrect implementation of MOD_SEL register
pin assignment for R8A7795 ES2.0 SoC specification of R-Car Gen3 Hardware
User's Manual Rev.0.51E or later.

Subject: pinctrl: sh-pfc: r8a7795: Fix MOD_SEL register pin assignment for
 TCLK{1,2}_{A,B} pins group

This patch fixes to set MOD_SEL2 bit19 when using TCLK2_A pin function is
selected for IPSR16 bit[23:20] or using TCLK2_B pin function is selected
for IPSR17 bit[27:24]. And renames MOD_SEL2 bit26 value definition name
to SEL_TIMER_TMU1.

This is a correction because MOD_SEL register specification for R8A7795
ES2.0 SoC was changed in R-Car Gen3 Hardware User's Manual Rev.0.53E.

Subject: drm: omapdrm: Register omapdrm platform device in omapdss driver

The omapdrm platform device is a virtual device created for the sole
purpose of handling the omapdss/omapdrm driver split. It should
eventually be removed. As a first step to ease refactoring move its
registration from platform code to driver code.

The omapdrm driver name must be changed internally to avoid probing both
the device registered in platform code and the device registered in the
omapdss driver, as that would otherwise break bisection.

Now that creating the omapdrm device from the platform code has been
removed, we can rename the omapdrm device back to "omapdrm".

Subject: drm/omap: remove no-op cleanup code

The driver sets crtc and plane rotation properties back to 0 degrees in
dev_lastclose() using drm_object_property_set_value().
drm_object_property_set_value() doesn't do anything with atomic drivers,
and a recent change added WARN_ON() when atomic driver calls the
function.

So remove the code.

Subject: drm/i915/vbt: ignore extraneous child devices for a port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ever since we've parsed VBT child devices, starting from 6acab15a7b0d
("drm/i915: use the HDMI DDI buffer translations from VBT"), we've
ignored the child device information if more than one child device
references the same port. The rationale for this seems lost in time.

Since commit 311a20949f04 ("drm/i915: don't init DP or HDMI when not
supported by DDI port") we started using this information more to skip
HDMI/DP init if the port wasn't there per VBT child devices. However, at
the same time it added port defaults without further explanation.

Thus, if the child device info was skipped due to multiple child devices
referencing the same port, the device info would be retrieved from the
somewhat arbitrary defaults.

Finally, when commit bb1d132935c2 ("drm/i915/vbt: split out defaults
that are set when there is no VBT") stopped initializing the defaults
whenever VBT is present, thus trusting the VBT more, we stopped
initializing ports which were referenced by more than one child device.

Apparently at least Asus UX305UA, UX305U, and UX306U laptops have VBT
child device blocks which cause this behaviour. Arguably they were
shipped with a broken VBT.

Relax the rules for multiple references to the same port, and use the
first child device info to reference a port. Retain the logic to debug
log about this, though.

Subject: Bluetooth: hci_bcm: Use operation speed of 4Mbps only for ACPI
 devices

Not all Broadcom controller support the 4Mbps operational speed on UART
devices. This is because the UART clock setting changes might not be
supported.

  < HCI Command: Broadcom Write UART Clock Setting (0x3f|0x0045) plen 1
         01                                               .
  > HCI Event: Command Complete (0x0e) plen 4
       Broadcom Write UART Clock Setting (0x3f|0x0045) ncmd 1
         Status: Unknown HCI Command (0x01)

To support any operational speed higher than 3Mbps, support for this
command is required. With that respect it is better to not enforce any
operational speed by default. Only when its support is known, then allow
for higher operational speed.

This patch assigns the 4Mbps opertional speed only for devices
discovered through ACPI and leave all others at the default 115200.

Subject: RDMA/vmw_pvrdma: Report CQ missed events

There is a chance of a race between arming the CQ and receiving
completions. By reporting CQ missed events any ULPs should poll
again to get the completions.

Subject: drm/i915: Initialize 'data' in intel_dsi_dcs_backlight.c

variable 'data' may be used uninitialized in this function. thus,
'function dcs_get_backlight' will return unwanted value/fail.

Thus, adding NULL initialized to 'data' variable will solve the return
failure happening.

Subject: drm/i915/vbt: ignore extraneous child devices for a port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ever since we've parsed VBT child devices, starting from 6acab15a7b0d
("drm/i915: use the HDMI DDI buffer translations from VBT"), we've
ignored the child device information if more than one child device
references the same port. The rationale for this seems lost in time.

Since commit 311a20949f04 ("drm/i915: don't init DP or HDMI when not
supported by DDI port") we started using this information more to skip
HDMI/DP init if the port wasn't there per VBT child devices. However, at
the same time it added port defaults without further explanation.

Thus, if the child device info was skipped due to multiple child devices
referencing the same port, the device info would be retrieved from the
somewhat arbitrary defaults.

Finally, when commit bb1d132935c2 ("drm/i915/vbt: split out defaults
that are set when there is no VBT") stopped initializing the defaults
whenever VBT is present, thus trusting the VBT more, we stopped
initializing ports which were referenced by more than one child device.

Apparently at least Asus UX305UA, UX305U, and UX306U laptops have VBT
child device blocks which cause this behaviour. Arguably they were
shipped with a broken VBT.

Relax the rules for multiple references to the same port, and use the
first child device info to reference a port. Retain the logic to debug
log about this, though.

When LSPCON support was extended to CNL
one part was missed on lspcon_init.

So, instead of adding check per platform on lspcon_init
let's use HAS_LSPCON that is already there for that
purpose.

Modify existing code, for automatically picking the spi bus number based
on Linux idr scheme as mentioned in FIXME.
This patch does the following:
(a) Remove the now unnecessary code which was allocating bus numbers using
    ATOMIC_INIT and atomic_dec_return macros.
(b) If we have an alias, pick the bus number from alias ID
(c) Convert to linux idr interface

Subject: IB/core: Protect sysfs entry on ib_unregister_device

ib_unregister_device is not protecting removal of sysfs entries.
A call to ib_register_device in that window can result in
duplicate sysfs entry warning. Move mutex_unlock to after
ib_device_unregister_sysfs to protect against sysfs entry creation.

This issue is exposed during driver load/unload stress test.

Previously, num_pages_onlined was updated using value from memory online

host. We should update num_pages_onlined only when the balloon driver
marks a page as online.

Subject: Drivers: hv: kvp: Use MAX_ADAPTER_ID_SIZE for translating adapter id

There's a bug which passes the output buffer size as MAX_IP_ADDR_SIZE,
when converting the adapter_id field to UTF16. This is much larger than
the actual size (MAX_ADAPTER_ID_SIZE). Fix this by passing the proper
size.

Fortunately, the translation is limited by the length of the input. This
explains why we haven't seen output buffer overflow conditions.

Subject: Drivers: hv: vmbus: Fix rescind handling issues

This patch handles the following issues that were observed when we are
handling racing channel offer message and rescind message for the same
offer:

1. Since the host does not respond to messages on a rescinded channel,
in the current code, we could be indefinitely blocked on the vmbus_open() call.

2. When a rescinded channel is being closed, if there is a pending interrupt on the
channel, we could end up freeing the channel that the interrupt handler would run on.

Subject: ACPI: SPCR: work around clock issue on xgene UART

xgene v1/v2 8250 UARTs don't run at the standard clock rate expected by
the driver and there is no information on clocking available from the
SPCR table. As there has been no progress on relevant vendors updating
DBG2/SPCR specifications to fix this work around this using the previous
xgene quirk handling to avoid setting a baud rate and therefore using
the UART as configured by firmware.

Subject: PCI: altera: Use size=4 IRQ domain for legacy INTx

The devicetree binding documentation for the Altera PCIe controller shows
an example which uses an interrupt-map property to map PCI INTx interrupts
to hardware IRQ numbers 1-4. The driver creates an IRQ domain with size 5
in order to cover this range, with hwirq=0 left unused.

This patch cleans up this wasted IRQ domain entry, modifying the driver to
use an IRQ domain of size 4 which matches the actual number of PCI INTx
interrupts. Since the hwirq numbers 1-4 are part of the devicetree binding,
and this is considered ABI, we cannot simply change the interrupt-map
property to use the range 0-3. Instead we make use of the
pci_irqd_intx_xlate() helper function to translate the range 1-4 used at
the DT level into the range 0-3 which is now used within the driver, and
stop adding 1 to decoded hwirq numbers in altera_pcie_isr().

Whilst cleaning up INTx handling we make use of the new PCI_NUM_INTX macro
& drop the custom INTX_NUM definition.

Subject: PCI: faraday: Fix of_irq_get() error check

of_irq_get() may return a negative error number as well as 0 on failure,
while the driver only checks for 0, blithely continuing with the call to
irq_set_chained_handler_and_data() -- that function expects *unsigned int*
so should probably do nothing when a large IRQ number resulting from a
conversion of a negative error number is passed to it. The driver then
probes successfully while being only partly functional...

Check for 'irq <= 0' instead and propagate the negative error number to the
probe method --  that will allow the deferred probing as well.

Subject: PCI: xilinx: Translate INTx range to hwirqs 0-3

The pcie-xilinx driver creates an IRQ domain of size 4 for legacy PCI INTx
interrupts, which at first glance seems reasonable since there are 4
possible such interrupts. Unfortunately the driver then proceeds to use the
range 1-4 as the hwirq numbers for INTA-INTD, causing warnings & broken
interrupts when attempting to use INTD/hwirq=4 due to it being beyond the
range of the IRQ domain:

  WARNING: CPU: 0 PID: 1 at kernel/irq/irqdomain.c:365

Fix this by making use of the new pci_irqd_intx_xlate() helper to translate
the INTx 1-4 range into the 0-3 range suitable for the IRQ domain of size
4, and stop adding 1 to the hwirq number decoded from the interrupt FIFO
which is already in the range 0-3.

Whilst we're here we switch to using PCI_NUM_INTX rather than the magic
number 4, making it clearer what the 4 means.

Subject: PCI: xilinx-nwl: Translate INTx range to hwirqs 0-3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The devicetree binding documentation for the Xilinx NWL PCIe root port
bridge shows an example which uses an interrupt-map property to map PCI
INTx interrupts to hardware IRQ numbers 1-4. The driver creates an IRQ
domain with size 4, which therefore covers the hwirq range 0-3.

This means that if we attempt to make use of the INTD interrupt then we're
likely to hit a WARN() in irq_domain_associate() because INTD, or hwirw=4,
is outside of the range covered by the IRQ domain.  irq_domain_associate()
will then return -EINVAL and we'll be unable to make use of INTD.

Fix this by making use of the pci_irqd_intx_xlate() helper function to
translate the 1-4 range used in the DT to a 0-3 range used within the
driver, and stop adding 1 to decoded hwirq numbers.

Whilst cleaning up INTx handling we make use of the new PCI_NUM_INTX macro
& drop the custom INTX definitions.

Subject: PCI: xilinx: Unify INTx & MSI interrupt decode

The INTx & MSI interrupt decode paths duplicated a fair bit of common
functionality. They also strictly handled interrupts in order of INTx then
MSI, so if both types of interrupt were to be asserted simultaneously and
the MSI interrupt were first in the FIFO then the INTx code would read it &
ignore it before the MSI code then had to read it again, wasting the
original FIFO read.

Unify the INTx & MSI decode in order to reduce that duplication & allow a
single FIFO read to be performed for each interrupt regardless of its type.

The Xilinx AXI bridge for PCI Express device provides interrupts indicating
the completion of config space accesses. We have previously
enabled/unmasked them but do nothing with them besides acknowledge them.

Leave the interrupts masked in order to avoid servicing a large number of
pointless interrupts during boot.

Subject: liquidio: update VF's netdev->max_mtu if there's a change in PF's MTU

A VF's MTU is capped at the parent PF's MTU.  So if there's a change in the
PF's MTU, then update the VF's netdev->max_mtu.

Also remove duplicate log messages for MTU change.

The previous fix removed the equal to zero comparisons by the strcmps and
now the function always returns true. Revert this change to restore the
original correctly functioning code.

Detected by CoverityScan, CID#1452267 ("Constant expression result")

This reverts commit b93ad9a067e1515af42da7d56bc61f1a25075f94.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

virtio_gpu_mode_dumb_destroy() is the same as drm_gem_dumb_destroy()
which is the drm_driver.dumb_destroy default, so no need to set it.

Subject: nfp: process control messages in workqueue in flower app

Processing of control messages is not time-critical and future processing
of some messages will require taking the RTNL which is not possible
in a BH handler. It seems simplest to move all control message processing
to a workqueue.

From 37c342cba5ef1ccb51f88a4aa5c1e74f793750c7 Mon Sep 17 00:00:00 2001
From: Rob Herring <robh@kernel.org>
Date: Tue, 18 Jul 2017 16:43:29 -0500
Subject: soc: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: memory: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: drm/tinydrm: make function st7586_pipe_enable static
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function st7586_pipe_enable  is local to the source
and does not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'st7586_pipe_enable' was not declared. Should it be static?

Subject: soc: versatile: remove unnecessary static in realview_soc_probe()

Remove unnecessary static on local variables syscon_regmap.
Such variables are initialized before being used, on every
execution path throughout the functions. The static has no
benefit and, removing it reduces the object file size.

This issue was detected using Coccinelle and the following
semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:

Subject: tun: make tun_build_skb() thread safe

tun_build_skb() is not thread safe since it uses per queue page frag,
this will break things when multiple threads are sending through same
queue. Switch to use per-thread generator (no lock involved).

Fixes: 66ccbc9c87c2 ("tap: use build_skb() for small packet")

dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.

Subject: usb: host: xhci: plat: re-fact xhci_plat_priv for R-Car Gen3

Since the firmware_name is decided by xhci-rcar.c on R-Car Gen3 now,
this patch removes 2 things:
 - Remove struct xhci_plat_priv xhci_plat_renesas_rcar_r8a7796.
 - Remoce .firmware_name from xhci_plat_renesas_rcar_gen3.

The behavior is the same as before.

Subject: usb: Increase root hub reset signaling time to prevent retry

Save 80ms device enumeration time by increasing root hub port reset time

The 50ms reset signaling time is not enough for most root hub ports.
Increasing the reset time to 60ms allows host controllers to finish port
reset and removes a retry causing an extra 50ms delay.

The USB 2 specification requires "at least 50ms" for driving root
port reset. The current msleep is exactly 50ms which may not be
enough if there are any delays between writing the reset bit to host
controller portsc register and phy actually driving reset.

On Haswell, Skylake and Kabylake xHC port reset took in average 52-59ms

The 80ms improvement comes from (40ms * 2 port resets) save at enumeration
for each device connected to a root hub port.

more details about root port reset in USB2 section 7.1.7.5:.
"Software must ensure that resets issued to the root ports drive reset
long enough to overwhelm any concurrent resume attempts by downstream
devices. It is required that resets from root ports have a duration of
at least 50 ms (TDRSTR).

Subject: xhci: rework bus_resume and check ports are suspended before resuming
 them.

bus_resume() tried to resume the same ports the bus_suspend()
suspeded. This caused PLC timeouts in case a suspended device disconnected
and was not in a resumable state at bus_resume().

Add a check to make sure the link state is either U3 or resuming
before actually resuming the link.

At the same time do some other changes such as make sure we remove
wake on connect/disconnect/overcurrent also for the resuming ports,
and avoid extra portsc port register writes.

This improves resume time with 10ms in those PLC timeout cases where
devices disconnect at suspend/resume cycle.

if megasas_io_attach return error, then goto fail_io_attach,
megasas_mgmt_info.instance has a wrong index here. So first reduce

Subject: scsi: sd_zbc: Write unlock zone from sd_uninit_cmnd()

Releasing a zone write lock only when the write commnand that acquired
the lock completes can cause deadlocks due to potential command
reordering if the lock owning request is requeued and not executed. This
problem exists only with the scsi-mq path as, unlike the legacy path,
requests are moved out of the dispatch queue before being prepared and
so before locking a zone for a write command.

Since sd_uninit_cmnd() is now always called when a request is requeued,
call sd_zbc_write_unlock_zone() from that function for write requests
that acquired a zone lock instead of from sd_done(). Acquisition of a zone
lock by a write command is indicated using the new command
flag SCMD_ZONE_WRITE_LOCK.

Subject: Revert "scsi: default to scsi-mq"

Defaulting to scsi-mq in 4.13-rc has shown various regressions
on setups that we didn't previously consider.  Fixes for them are
in progress, but too invasive to make it in this cycle.  So for
now revert the commit that defaults to blk-mq for SCSI.  For 4.14
we'll plan to try again with these fixes.

This reverts commit 5c279bd9e40624f4ab6e688671026d6005b066fa.

Subject: mwifiex: do not use random MAC for pre-association scanning

Driver should use random MAC address only if the scan is
requested by user(provided NL80211_SCAN_FLAG_RANDOM_ADDR
is set in scan request). It should not be used for a scan
performed before association.

Subject: mwifiex: check for NL80211_SCAN_FLAG_RANDOM_ADDR during hidden SSID
 scan

At the end of user scan request, driver will perform an active
scan for hidden SSIDs in passive channels. While doing this,
driver unconditionally adding random_mac in scan command, which
is no expected. It should add random_mac only if scan_request
has NL80211_SCAN_FLAG_RANDOM_ADDR flag set.

Subject: qtnfmac: modify tx reclaim locking

Perform additional reclaim from qtnf_pcie_data_tx. Lock tx_lock serves only
reclaim synchronization purposes. Rename it accordingly and improve
granularity moving this lock to qtnf_pcie_data_tx_reclaim.

Subject: rsi: add beacon changes for AP mode

Mac80211 config parameter BEACON_ENABLE is handled. When VAP
capabilities frame with AP mode is configured to firmware, beacon
events start coming to host at each PreTBTT. At this time, beacon
is taken from mac80211, descriptor is prepared and send to firmware.

Subject: rsi: handle station connection in AP mode

Station structures are maintained in driver with required
fields. When mac80211 callback sta_add is called, driver
iterates through list of connected stations to check available
index and assigns station id which is important for further
communication to that station. Then peer notify frame is send
to firmware to inform the firmware about new station connection.

Subject: rsi: security enhancements for AP mode

Station id should be set in load key frame configured to device.
For WEP mode, key is configured once from mac80211. This key is
saved and configured to device every time a station is connected.

Subject: clk: renesas: rcar-usb2-clock-sel: Add R-Car USB 2.0 clock selector
 PHY

R-Car USB 2.0 controller can change the clock source from an oscillator
to an external clock via a register. So, this patch adds support
the clock source selector as a clock driver.

+* Renesas R-Car USB 2.0 clock selector
+
+This file provides information on what the device node for the R-Car USB 2.0
+clock selector.
+
+If you connect an external clock to the USB_EXTAL pin only, you should set
+the clock rate to "usb_extal" node only.
+If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
+is not needed because this is default setting. (Of course, you can set the
+clock rates to both "usb_extal" and "usb_xtal" nodes.
+
+Case 1: An external clock connects to R-Car SoC
+	+----------+   +--- R-Car ---------------------+
+	|External  |---|USB_EXTAL ---> all usb channels|
+	|clock     |   |USB_XTAL                       |
+	+----------+   +-------------------------------+
+In this case, we need this driver with "usb_extal" clock.
+
+Case 2: An oscillator connects to R-Car SoC
+	+----------+   +--- R-Car ---------------------+
+	|Oscillator|---|USB_EXTAL -+-> all usb channels|
+	|          |---|USB_XTAL --+                   |
+	+----------+   +-------------------------------+
+In this case, we don't need this selector.
+
+Required properties:
+- compatible: "renesas,r8a7795-rcar-usb2-clock-sel" if the device is a part of
+	      an R8A7795 SoC.
+	      "renesas,r8a7796-rcar-usb2-clock-sel" if the device if a part of
+	      an R8A7796 SoC.
+	      "renesas,rcar-gen3-usb2-clock-sel" for a generic R-Car Gen3
+	      compatible device.
+
+	      When compatible with the generic version, nodes must list the
+	      SoC-specific version corresponding to the platform first
+	      followed by the generic version.
+
+- reg: offset and length of the USB 2.0 clock selector register block.
+- clocks: A list of phandles and specifier pairs.
+- clock-names: Name of the clocks.
+ - The functional clock must be "ehci_ohci"
+ - The USB_EXTAL clock pin must be "usb_extal"
+ - The USB_XTAL clock pin must be "usb_xtal"
+- #clock-cells: Must be 0
+
+Example (R-Car H3):
+
+	usb2_clksel: clock-controller@e6590630 {
+		compatible = "renesas,r8a77950-rcar-usb2-clock-sel",
+			     "renesas,rcar-gen3-usb2-clock-sel";
+		reg = <0 0xe6590630 0 0x02>;
+		clocks = <&cpg CPG_MOD 703>, <&usb_extal>, <&usb_xtal>;
+		clock-names = "ehci_ohci", "usb_extal", "usb_xtal";
+		#clock-cells = <0>;

Subject: of: fix DMA mask generation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Historically, DMA masks have suffered some ambiguity between whether
they represent the range of physical memory a device can access, or the
address bits a device is capable of driving, particularly since on many
platforms the two are equivalent. Whilst there are some stragglers left
(dma_max_pfn(), I'm looking at you...), the majority of DMA code has
been cleaned up to follow the latter definition, not least since it is
the only one which makes sense once IOMMUs are involved.

In this respect, of_dma_configure() has always done the wrong thing in
how it generates initial masks based on "dma-ranges". Although rounding
down did not affect the TI Keystone platform where dma_addr + size is
already a power of two, in any other case it results in a mask which is
at best unnecessarily constrained and at worst unusable.

BCM2837 illustrates the problem nicely, where we have a DMA base of 3GB
and a size of 1GB - 16MB, giving dma_addr + size = 0xff000000 and a
resultant mask of 0x7fffffff, which is then insufficient to even cover
the necessary offset, effectively making all DMA addresses out-of-range.
This has been hidden until now (mostly because we don't yet prevent
drivers from simply overwriting this initial mask later upon probe), but
due to recent changes elsewhere now shows up as USB being broken on
Raspberry Pi 3.

Make it right by rounding up instead of down, such that the mask
correctly correctly describes all possisble bits the device needs to
emit.

Subject: efi: Introduce efi_early_memdesc_ptr to get pointer to memmap
 descriptor

The existing map iteration helper for_each_efi_memory_desc_in_map can
only be used after the kernel initializes the EFI subsystem to set up
struct efi_memory_map.

Before that we also need iterate map descriptors which are stored in several
intermediate structures, like struct efi_boot_memmap for arch independent
usage and struct efi_info for x86 arch only.

Introduce efi_early_memdesc_ptr() to get pointer to a map descriptor, and
replace several places where that primitive is open coded.

The direction used in dma_unmap_sg in aes calc is wrong.
This result in the cache not being invalidated correct when aes
calculation is done and result has been dma'ed to memory.
This is seen as sporadic wrong result from aes calc.

This driver previously used a spinlock. The spinlock is not
used any more, but the spinlock variable was still there
and also being initialized.

The return value of dma_map_single() should be checked by

return value is checked against NULL, which could result in failures.

Subdevices of bpmp, such as bpmp-i2c, require the bpmp device's
drvdata to be set during their probe. Currently this is not always the
case. Fix this by calling platform_set_drvdata() earlier during bpmp's
probe.

Subject: powerpc/mm/cxl: Add the fault handling cpu to mm cpumask

We use mm cpumask for serializing against lockless page table walk.
Anybody who is doing a lockless page table walk is expected to disable
irq and only cpus in mm cpumask is expected do the lockless walk. This
ensure that a THP split can send IPI to only cpus in the mm cpumask,
to make sure there are no parallel lockless page table walk.

Add the CAPI fault handling cpu to the mm cpumask so that we can do
the lockless page table walk while inserting hash page table entries.

Subject: drm/i915/opregion: let user specify override VBT via firmware load

Sometimes it would be most enlightening to debug systems by replacing
the VBT to be used. For example, in the referenced bug the BIOS provides
different VBT depending on the boot mode (UEFI vs. legacy). It would be
interesting to try the failing boot mode with the VBT from the working
boot, and see if that makes a difference.

Add a module parameter to load the VBT using the firmware loader, not
unlike the EDID firmware mechanism.

As a starting point for experimenting, one can pick up the BIOS provided
VBT from /sys/kernel/debug/dri/0/i915_opregion/i915_vbt.

v2: clarify firmware load return value check (Bob)

v3: kfree the loaded firmware blob

Subject: spi: imx: dynamic burst length adjust for PIO mode

previously burst length (BURST_LENGTH) is always set to equal
to bits_per_word, causes a 10us gap between each word in
transfer, which significantly affects performance.

This patch uses 32 bits transfer to simulate lower bits transfer,
and adjusts burst length runtimely to use biggeest burst length
as possible to reduce the gaps in transfer for PIO mode.

Subject: soc/tegra: Register SoC device

Move this code from arch/arm/mach-tegra and make it common among 32-bit
and 64-bit Tegra SoCs. This is slightly complicated by the fact that on
32-bit Tegra, the SoC device is used as the parent for all devices that
are instantiated from device tree.

Subject: drivers/ata: Replace spin_unlock_wait() with lock/unlock pair

There is no agreed-upon definition of spin_unlock_wait()'s semantics,
and it appears that all callers could do just as well with a lock/unlock
pair.  This commit therefore eliminates the spin_unlock_wait() call and
associated else-clause and hoists the then-clause's lock and unlock out of
the "if" statement.  This should be safe from a performance perspective
because according to Tejun there should be few if any drivers that don't
set their own error handler.

Subject: i2c: designware: Remove needless pm_runtime_put_noidle() call

I guess pm_runtime_put_noidle() call in i2c_dw_probe_slave() was copied
by accident from similar master mode adapter registration code. It is
unbalanced due missing pm_runtime_get_noresume() but harmless since it
doesn't decrease dev->power.usage_count below zero.

In theory we can hit similar needless runtime suspend/resume cycle
during slave mode adapter registration that was happening when
registering the master mode adapter. See commit cd998ded5c12 ("i2c:
designware: Prevent runtime suspend during adapter registration").

However, since we are slave, we can consider it as a wrong configuration
if we have other slaves attached under this adapter and can omit the
pm_runtime_get_noresume()/pm_runtime_put_noidle() calls for simplicity.

Subject: i2c: designware: Fix runtime PM for I2C slave mode

I2C slave controller must be powered and active all the time when I2C
slave backend is registered in order to let master address and
communicate with us.

Now if the controller is runtime PM capable it will be suspended after
probe and cannot ever respond to the master or generate interrupts.

Fix this by resuming the controller when I2C slave backend is registered
and let it suspend after unregistering.

Some parts of Host1x uses BIT_WORD/BIT_MASK/BITS_PER_LONG to calculate
register or field offsets. This worked fine on ARMv7, but now that
BITS_PER_LONG is 64 but our registers are still 32-bit things are
broken.

Fix by replacing..
- BIT_WORD with (x / 32)
- BIT_MASK with BIT(x % 32)
- BITS_PER_LONG with 32

Subject: gpu: host1x: fix error return code in host1x_probe()

platform_get_irq() returns an error code, but the host1x driver
ignores it and always returns -ENXIO. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Notice that platform_get_irq() no longer returns 0 on error:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

The display architecture in Tegra186 changes slightly compared to
earlier Tegra generations, which requires that we recursively scan
host1x sub-devices from device tree.

The defines are set anyway to prevent an empty string. The test for the
SoC is the same as for Nouveau for the Tegra GPU firmware (see
drivers/gpu/drm/nouveau/nouveau_platform.c)

v2:
 - Place the defines above each chip's vic_config struct
 - MODULE_FIRMWARE() at the end of the file

Subject: drm/tegra: switch to drm_*_get(), drm_*_put() helpers

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

Subject: drm/tegra: Prevent BOs from being freed during job submission

Since DRM IOCTL's are lockless, there is a chance that BOs could be
released while a job submission is in progress. To avoid that, keep the
GEM reference until the job has been pinned, part of which will be to
take another reference.

v2: remove redundant check and avoid memory leak

Subject: pty: fix the cached path of the pty slave file descriptor in the
 master

Christian Brauner reported that if you use the TIOCGPTPEER ioctl() to
get a slave pty file descriptor, the resulting file descriptor doesn't
look right in /proc/<pid>/fd/<fd>.  In particular, he wanted to use
readlink() on /proc/self/fd/<fd> to get the pathname of the slave pty
(basically implementing "ptsname{_r}()").

The reason for that was that we had generated the wrong 'struct path'
when we create the pty in ptmx_open().

In particular, the dentry was correct, but the vfsmount pointed to the
mount of the ptmx node. That _can_ be correct - in case you use
"/dev/pts/ptmx" to open the master - but usually is not.  The normal
case is to use /dev/ptmx, which then looks up the pts/ directory, and
then the vfsmount of the ptmx node is obviously the /dev directory, not
the /dev/pts/ directory.

We actually did have the right vfsmount available, but in the wrong
place (it gets looked up in 'devpts_acquire()' when we get a reference
to the pts filesystem), and so ptmx_open() used the wrong mnt pointer.

The end result of this confusion was that the pty worked fine, but when
if you did TIOCGPTPEER to get the slave side of the pty, end end result
would also work, but have that dodgy 'struct path'.

And then when doing "d_path()" on to get the pathname, the vfsmount
would not match the root of the pts directory, and d_path() would return
an empty pathname thinking that the entry had escaped a bind mount into
another mount.

This fixes the problem by making devpts_acquire() return the vfsmount
for the pts filesystem, allowing ptmx_open() to trivially just use the
right mount for the pts dentry, and create the proper 'struct path'.

"spi: Pick spi bus number from Linux idr or spi alias"
(SHA1:9b61e302210eba55768962f2f11e96bb508c2408)
has introduced some checkpatch issues. As pointed by
Lukas Wunner this patch does the following:
- remove whitespaces
- fix warnings, suspect code indent for conditional statements
- fix errors, code indent should use tabs
- remove spaces at the start of the line

Subject: ACPI: EC: Fix regression related to wrong ECDT initialization order

Commit 2a5708409e4e (ACPI / EC: Fix a gap that ECDT EC cannot handle
EC events) introduced acpi_ec_ecdt_start(), but that function is
invoked before acpi_ec_query_init(), which is too early.  This causes
the kernel to crash if an EC event occurs after boot, when ec_query_wq
is not valid:

 BUG: unable to handle kernel NULL pointer dereference at 0000000000000102
 ...
 Workqueue: events acpi_ec_event_handler
 task: ffff9f539790dac0 task.stack: ffffb437c0e10000
 RIP: 0010:__queue_work+0x32/0x430

Normally, the DSDT EC should always be valid, so acpi_ec_ecdt_start()
is actually a no-op in the majority of cases.  However, commit
c712bb58d827 (ACPI / EC: Add support to skip boot stage DSDT probe)
caused the probing of the DSDT EC as the "boot EC" to be skipped when
the ECDT EC is valid and uncovered the bug.

Fix this issue by invoking acpi_ec_ecdt_start() after acpi_ec_query_init()
in acpi_ec_init().

Subject: ACPICA: Dispatch active GPEs at init time

In some cases GPEs are already active when they are enabled by
acpi_ev_initialize_gpe_block() and whatever happens next may depend
on the result of handling the events signaled by them, so the
events should not be discarded (which is what happens currently) and
they should be handled as soon as reasonably possible.

For this reason, modify acpi_ev_initialize_gpe_block() to
dispatch GPEs with the status flag set in-band right after
enabling them.

Date: Thu, 10 Aug 2017 00:31:58 +0200
Subject: ACPICA: Make it possible to enable runtime GPEs earlier

Runtime GPEs have corresponding _Lxx/_Exx methods and are enabled
automatically during the initialization of the ACPI subsystem through
acpi_update_all_gpes() with the assumption that acpi_setup_gpe_for_wake()
will be called in advance for all of the GPEs pointed to by _PRW
objects in the namespace that may be affected by acpi_update_all_gpes().
That is, acpi_ev_initialize_gpe_block() can only be called for a GPE
block after acpi_setup_gpe_for_wake() has been called for all of the
_PRW (wakeup) GPEs in it.

The platform firmware on some systems, however, expects GPEs to be
enabled before the enumeration of devices which is when
acpi_setup_gpe_for_wake() is called and that goes against the above
assumption.

For this reason, introduce a new flag to be set by
acpi_ev_initialize_gpe_block() when automatically enabling a GPE
to indicate to acpi_setup_gpe_for_wake() that it needs to drop the
reference to the GPE coming from acpi_ev_initialize_gpe_block()
and modify acpi_setup_gpe_for_wake() accordingly.  These changes
allow acpi_setup_gpe_for_wake() and acpi_ev_initialize_gpe_block()
to be invoked in any order.

Subject: ACPI / scan: Enable GPEs before scanning the namespace

On some systems the platform firmware expects GPEs to be enabled
before the enumeration of devices and if that expectation is not
met, the systems in question may not boot in some situations.

For this reason, change the initialization ordering of the ACPI
subsystem to make it enable GPEs before scanning the namespace
for the first time in order to enumerate devices.

Subject: drm/ttm: remove nonsense wait in ttm_bo_cleanup_refs_and_unlock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With shared reservation objects the assumption that no fence
could have been added isn't true any more.

Additional to that the BO is about to be destroyed, so removing the
fences now has no advantage whatsoever.

Subject: drm/ttm: individualize BO reservation obj when they are freed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use the BOs reservation object when it is put on the ddelete list. This way we
avoid delaying freeing up the BO because of new fences on the reservation object.

This is used by dma-buf and amdgpu's VM page tables.

Subject: drm/amdgpu: only move VM BOs in the LRU during validation v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This should save us a bunch of command submission overhead.

v2: move the LRU move to the right place to avoid the move for the root BO
    and handle the shadow BOs as well. This turned out to be a bug fix because
    the move needs to happen before the kmap.

Subject: drm/amd/amdgpu: Add tracepoint for DMA page mapping (v4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This helps map DMA addresses back to physical addresses.

(v2):  Added tracepoints for USERPTR, SG mappings, and
     SWIOTBL mappings.  Reformatted trace call perform
     PCI decoding internal to the trace.

(v3):  Add unmap tracepoints as well

(v4):  Move traces into separate functions

Subject: drm/amdgpu: drop the extra VM huge page flag v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Just add the flags to the addr field as well.

v2: add some more comments that the flag is for huge pages.

Subject: Bluetooth: hci_bcm: Handle empty packet after firmware loading

The Broadcom controller on the Raspberry Pi3 sends an empty packet with
packet type 0x00 after launching the firmware. This will cause logging
of errors.

  Bluetooth: hci0: Frame reassembly failed (-84)

Since this seems to be an intented behaviour of the controller, handle
it gracefully by parsing that empty packet with packet type 0x00 and
then just simply report it as diagnostic packet.

With that change no errors are logging and the packet itself is actually
recorded in the Bluetooth monitor traces.

  < HCI Command: Broadcom Launch RAM (0x3f|0x004e) plen 4
         Address: 0xffffffff
  > HCI Event: Command Complete (0x0e) plen 4

Subject: i2c-cht-wc: Ack read irqs after reading the data register

Testing has shown that writing 1 to clear the read-complete irq does
not work until the data register has been read first.

This commit fixes the driver to read the data register first, halving the
amount of interrupts in most cases since we mostly read on this i2c bus.

Subject: i2c-cht-wc: Workaround CHT GPIO controller IRQ issues

The Cherry Trail Whiskey Cove PMIC's IRQ line is attached to one of
the GPIOs of the Cherry Trail SoC. The CHT GPIO controller sometimes
fails to deliver IRQs (seen when there is an IRQ storm on another pin).

This commit works around this by reducing the long timeout which was
a poor attempt to workaround this from 3s to 30ms and after that
manually checking the status register for transfer completion by
calling the threaded IRQ handler directly.

This is safe todo as the entire threaded IRQ handler is protected
by a mutex.

Note 30ms should be more then long enough, at 100KHz any smbus single
byte transaction should be finished in 4ms.

Subject: Input: axp20x-pek - use driver_data of platform_device_id instead of
 extended attributes

To prepare an upcoming patch adding support for another PMIC that has
different startup and shutdown time, use driver_data of
platform_device_id instead of a fixed extended device attribute.

By doing so, we also remove a lot of nested structures that aren't
useful.

With this patch, a new PMIC can be easily supported by just filling
correctly its ax20x_info structure and adding a platform_device_id.

Moreover, since we get rid of extended attributes, rename
axp20x_store_ext_attr to axp20x_store_attr and axp20x_show_ext_attr to
axp20x_show_attr.

Subject: Input: i8042 - constify pnp_device_id

pnp_device_id are not supposed to change at runtime. All functions
working with pnp_device_id provided by <linux/pnp.h> work with
const pnp_device_id. So mark the non-const structs as const.

Subject: drm/i915: Split pin mapping into per platform functions

Cleanup the code. Map the pins in accordance to
individual platforms rather than according to ports.
Create separate functions for platforms.

v2:
 - Add missing condition for CoffeeLake. Make platform
 specific functions static. Add function
 i915_ddc_pin_mapping().

v3:
 - Rename functions to x_port_to_ddc_pin() which directly
   indicates the purpose. Correct default return values on CNP
   and BXT. Rename i915_port_to_ to g4x_port_to since that was
   the first platform to run this. Correct code style. (Paulo)

Subject: cpufreq: remove setting of policy->cpu in policy->cpus during init

policy->cpu is copied into policy->cpus in cpufreq_online() before
calling into cpufreq_driver->init(). So there's no need to set the
same in the individual driver init() functions again.

This patch removes the redundant setting of policy->cpu in policy->cpus
in intel_pstate and cppc drivers.

Subject: ACPI: Add debug statements to acpi_global_event_handler()

It sometimes is useful to examine the timing of ACPI events during
certain operations only, like during system suspend/resume, so add
pr_debug() statements for that to acpi_global_event_handler().

Subject: ACPI / PM: Check low power idle constraints for debug only

For SoC to achieve its lowest power platform idle state a set of hardware
preconditions must be met. These preconditions or constraints can be
obtained by issuing a device specific method (_DSM) with function "1".
Refer to the document provided in the link below.

Here during initialization (from attach() callback of LPS0 device), invoke
function 1 to get the device constraints. Each enabled constraint is
stored in a table.

The devices in this table are used to check whether they were in required
minimum state, while entering suspend. This check is done from platform
freeze wake() callback, only when /sys/power/pm_debug_messages attribute
is non zero.

If any constraint is not met and device is ACPI power managed then it
prints the device information to kernel logs.

Also if debug is enabled in acpi/sleep.c, the constraint table and state
of each device on wake is dumped in kernel logs.

Since pm_debug_messages_on setting is used as condition to check
constraints outside kernel/power/main.c, pm_debug_messages_on is changed
to a global variable.

Subject: bus: sunxi-rsb: Enable by default for ARM64

Allwinner's A64 SoC uses the "Reduced Serial Bus" to communicate with
its companion PMIC.

Since arm64 does not have separate defconfigs for each platform or
processor family, enable this driver by default for ARM64 as well.
Note that the Kconfig symbol already depends on ARCH_SUNXI.

Subject: drivers: soc: sunxi: fix error processing on base address when
 claiming

When claiming SRAM, if the base is set to an error, it means that the
SRAM controller has been probed, but failed to remap the controller
memory zone. If the base is zero, thus the SRAM controller should be not
probed at all, and it should return -EPROBE_DEFER. However, currently we
returned -EPROBE_DEFER in the former situation, and ignored the latter
situation (which will lead to the kernel to panic).

Fix the behavior on abnormal base address processing when claiming.

Subject: drivers: soc: sunxi: add support for remapping func value to reg
 value

On some Allwinner SoCs, sometimes the value needed to write into the
register to claim SRAM is not equal to the value specified in the
device tree.

The device tree binding defines 0 as "mapped to CPU" and 1 as "mapped
to X device". This matches the value written to the configuration
register for the SRAM blocks currently supported. However, the not yet
supported VE SRAM block is claimed for the device by writing 0x7fffffff,
which is vastly different from the other blocks. On the A64, SRAM C is
claimed by the device by writing a 0, which is the opposite of the
current design.

Add a value remapping in sunxi_sram_func structure, and let the
sunxi_sram_of_parse function set the remapped register value.
This allows us to keep the convention currently used in the device tree
binding.

From c5bf4a04467dca050784c9faef492ce17d268be9 Mon Sep 17 00:00:00 2001
From: Andreas Klinger <ak@it-klinger.de>
Date: Wed, 16 Aug 2017 21:34:23 +0200
Subject: iio: srf08: add sensor type srf10

Ultrasonic sensor srf10 is quite similar to srf08 and now also supported by
the driver as device tree compatible string.

It was necessary to prepare the source for supplementary sensors. This is
done by enum srf08_sensor_type.

The most significiant difference between srf08 and srf10 is another range
and values of register gain (in the driver it's call sensitivity).
Therefore the array of it is extended and dependent of the sensor type.

srf02 added with support for i2c interface

Attributes for setting max range or sensitivity are omitted for the case of
srf02 type sensor, because they are not supported by the hardware.

Subject: drm/gma500: fix potential NULL pointer dereference dereference

NULL check at line 528: if (!sender || !data_out || !len_out) {, implies
that pointer _sender_ might be NULL.

Move pointer _sender_ dereference after NULL check in order to avoid a
potential NULL pointer dereference.

This issue was detected with the help of Coccinelle.

Subject: USB: Gadget core: fix inconsistency in the interface
 tousb_add_gadget_udc_release()

The usb_add_gadget_udc_release() routine in the USB gadget core will
sometimes but not always call the gadget's release function when an
error occurs.  More specifically, if the struct usb_udc allocation
fails then the release function is not called, and for other errors it
is.

As a result, users of this routine cannot know whether they need to
deallocate the memory containing the gadget structure following an
error.  This leads to unavoidable memory leaks or double frees.

This patch fixes the problem by splitting the existing
device_register() call into device_initialize() and device_add(), and
doing the udc allocation in between.  That way, even if the allocation
fails it is still possible to call device_del(), and so the release
function will be always called following an error.

Subject: drm/i915: Stop touching forcewake following a gen6+ engine reset

Forcewake is not affected by the engine reset on gen6+. Indeed the
reason why we added intel_uncore_forcewake_reset() to
gen6_reset_engines() was to keep the bookkeeping intact because the
reset did not touch the forcewake bit (yet we cancelled the forcewake
consumers)!  This was done in commit 521198a2e7095:
    Author: Mika Kuoppala <mika.kuoppala@linux.intel.com>
    Date:   Fri Aug 23 16:52:30 2013 +0300

	drm/i915: sanitize forcewake registers on reset

	In reset we try to restore the forcewake state to
	pre reset state, using forcewake_count. The reset
	doesn't seem to clear the forcewake bits so we
	get warn on forcewake ack register not clearing.

That futzing of the forcewake bookkeeping was dropped in commit
0294ae7b44bb ("drm/i915: Consolidate forcewake resetting to a single
function"), but it did not make the realisation that the remaining
intel_uncore_forcewake_reset() was redundant.

The new danger with using intel_uncore_forcewake_reset() with per-engine
resets is that the driver and hw are still in an active state as we
perform the reset. We may be using the forcewake to read protected
registers elsewhere and those results may be clobbered by the concurrent
dropping of forcewake.

Subject: usb: gadget: serial: fix oops when data rx'd after close

When the gadget serial device has no associated TTY, do not pass any
received data into the TTY layer for processing; simply drop it instead.
This prevents the TTY layer from calling back into the gadget serial
driver, which will then crash in e.g. gs_write_room() due to lack of
gadget serial device to TTY association (i.e. a NULL pointer dereference).

Subject: iommu: Avoid NULL group dereference

The recently-removed FIXME in iommu_get_domain_for_dev() turns out to
have been a little misleading, since that check is still worthwhile even
when groups *are* universal. We have a few IOMMU-aware drivers which
only care whether their device is already attached to an existing domain
or not, for which the previous behaviour of iommu_get_domain_for_dev()
was ideal, and who now crash if their device does not have an IOMMU.

With IOMMU groups now serving as a reliable indicator of whether a
device has an IOMMU or not (barring false-positives from VFIO no-IOMMU
mode), drivers could arguably do this:

	group = iommu_group_get(dev);
	if (group) {
		domain = iommu_get_domain_for_dev(dev);
		iommu_group_put(group);
	}

However, rather than duplicate that code across multiple callsites,
particularly when it's still only the domain they care about, let's skip
straight to the next step and factor out the check into the common place
it applies - in iommu_get_domain_for_dev() itself. Sure, it ends up
looking rather familiar, but now it's backed by the reasoning of having
a robust API able to do the expected thing for all devices regardless.

Commit b6a1d093f96b ("PM / Domains: Extend generic power domain
debugfs") now creates a debugfs directory for each genpd based on the
name of the genpd. Currently no name is given to the genpd created by
ti_sci_pm_domains driver so because of this we see a NULL pointer
dereferences when it is accessed on boot when the debugfs entry creation
is attempted.

Give the genpd a name before registering it to avoid this.

Subject: drm/i915: Check context status before looking up our obj/vma

Since we keep the context around across the slow lookup where we may
drop the struct_mutex, we should double check that the context is still
valid upon reacquisition.

Subject: drm/i915: Convert execbuf to use struct-of-array packing for critical
 fields

When userspace is doing most of the work, avoiding relocs (using
NO_RELOC) and opting out of implicit synchronisation (using ASYNC), we
still spend a lot of time processing the arrays in execbuf, even though
we now should have nothing to do most of the time. One issue that
becomes readily apparent in profiling anv is that iterating over the
large execobj[] is unfriendly to the loop prefetchers of the CPU and it
much prefers iterating over a pair of arrays rather than one big array.

v2: Clear vma[] on construction to handle errors during vma lookup

Subject: drm/i915: Simplify eb_lookup_vmas()

Since the introduction of being able to perform a lockless lookup of an
object (i915_gem_object_get_rcu() in fbbd37b36fa5 ("drm/i915: Move object
release to a freelist + worker") we no longer need to split the
object/vma lookup into 3 phases and so combine them into a much simpler
single loop.

Subject: drm/i915: Replace execbuf vma ht with an idr

This was the competing idea long ago, but it was only with the rewrite
of the idr as an radixtree and using the radixtree directly ourselves,
along with the realisation that we can store the vma directly in the
radixtree and only need a list for the reverse mapping, that made the
patch performant enough to displace using a hashtable. Though the vma ht
is fast and doesn't require any extra allocation (as we can embed the node
inside the vma), it does require a thread for resizing and serialization
and will have the occasional slow lookup. That is hairy enough to
investigate alternatives and favour them if equivalent in peak performance.
One advantage of allocating an indirection entry is that we can support a
single shared bo between many clients, something that was done on a
first-come first-serve basis for shared GGTT vma previously. To offset
the extra allocations, we create yet another kmem_cache for them.

Subject: drm/i915: Mark the GT as busy before idling the previous request

In a synchronous setup, we may retire the last request before we
complete allocating the next request. As the last request is retired, we
queue a timer to mark the device as idle, and promptly have to execute
ad cancel that timer once we complete allocating the request and need to
keep the device awake. If we rearrange the mark_busy() to occur before
we retire the previous request, we can skip this ping-pong.

v2: Joonas pointed out that unreserve_seqno() was now doing more than
doing seqno handling and should be renamed to reflect its wider purpose.
That also highlighted the new asymmetry with reserve_seqno(), so fixup
that and rename both to [un]reserve_engine().

Subject: platform/x86: wmi: Fix check for method instance number
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

instance_count defines number of instances of data block and instance
itself is indexed from zero, which means first instance has number 0.
Therefore check for invalid instance should be non-strict inequality.

Subject: drm/i915/bxt: use NULL for GPIO connection ID

The commit 213e08ad60ba
	("drm/i915/bxt: add bxt dsi gpio element support")
enables GPIO support for Broxton based platforms.

While using that API we might get into troubles in the future, because
we can't rely on label name in the driver since vendor firmware might
provide any GPIO pin there, e.g. "reset", and even mark it in _DSD (in
which case the request will fail).

To avoid inconsistency and potential issues we have two options:
a) generate GPIO ACPI mapping table and supply it via
   acpi_dev_add_driver_gpios(), or
b) just pass NULL as connection ID.

The b) approach is much simpler and would work since the driver relies
on GPIO indices only. Moreover, the _CRS fallback mechanism, when
requesting GPIO, has been made stricter, and supplying non-NULL
connection ID when neither _DSD, nor GPIO ACPI mapping is present, is
making request fail.

Subject: iwlwifi: mvm: remove the corunning support

The corunning block was supposed to help in coex scenarios.
It required the driver to configure the firmware based on
the coupling between the two antennas of the devices.
This was never in use and the configuration sent by the
driver has always been blank.
Remove all that code.

Subject: iwlwifi: mvm: consider RFKILL during INIT as success

There's no need to differentiate an INIT that ended early because of
RFKILL from one that succeded.  Additionally, if INIT fails later,
during calibration, due to RFKILL, we can just return success and
continue as if we were already in RFKILL to start with.

Remove this unnecessary differentiation and do some other small
clean-ups while at it.

Subject: iwlwifi: call iwl_remove_notification from iwl_wait_notification

The iwl_wait_notification() function removes the wait entry from the
list.  To make it clearer that it's doing the same thing as
iwl_remove_notification(), call the latter instead of having duplicate
code.

Subject: iwlwifi: pcie: support short Tx queues for A000 device family

This allows to modify TFD_TX_CMD_SLOTS to a power of 2
which is smaller than 256.
Note that we still need to set values to wrap at 256
into the scheduler's write pointer, but all the rest of
the code can use shorter transmit queues.

Subject: iwlwifi: mvm: include more debug data when we get an unexpected baid

When we get a valid baid in a received frame, we need to
check that we are aware of this baid. If not, we check
that the OLD_SN bit set. If that's not the case, we issue
a WARNING. Print more data when that happens.

Subject: iwlwifi: mvm: group all dummy SAR function declarations together

We have some of the SAR dummy functions when ACPI is not set declared
in mvm.h and some declared in fw.c.  Group them all together in fw.c
for consistency and to avoid static/non-static issues.

Subject: iwlwifi: mvm: use mvmsta consistently in rs.c

We use mvmsta for the sta->drv_priv in mvm, but in rs.c we have a
bunch of instances using sta_priv, which is probably due to it being
copied from dvm.  Change all occurrences to mvmsta for consistency
with the rest of the driver

Subject: iwlwifi: mvm: update the firmware API in TX

The firmware team is now re-using a bit that hasn't been
used for a few generations. Re-use for TX_ON_AIR drop.
This bit will be set by the firmware to indicate that
a frame in an A-MPDU was dropped but not because of the
already mapped reasons.

Subject: iwlwifi: mvm: remove session protection to allow channel switch

If a time event is already scheduled when trying to schedule one for
channel switch, the code assumes the channel switch is already
scheduled and no further action is required.
However, it is possible that the scheduled time event is actually
for session protection (e.g. when the first beacon after association
contains the CSA IE). In this case the channel switch will not be
scheduled which will finally lead to disconnection.

Fix this by removing the old time event and schduling a new one for
the channel switch.

Subject: iwlwifi: mvm: don't send BAR on flushed frames

When we flush a queue, the packets will have a 'failed'
status but we shouldn't send a BAR. This check was missing.
Because of that, when we got an ampdu_action with
IEEE80211_AMPDU_TX_STOP_FLUSH, we started the following
ping pong with the firmware:

1) Set the station as 'draining'
2) Get a failed Tx status (DRAINED)
3) Send a BAR because of the failed Tx status

(loop of 2 and 3)

This loop wasn't endless since the BAR isn't sent on a
queue that would trigger a "nested" BAR.

Subject: ACPI: EC: Fix possible issues related to EC initialization order

Use the observation that the EC command/data register addresses are
sufficient to determine if two EC devices are equivelent to modify
acpi_is_boot_ec().

Then, for the removed comparison factors, EC ID and EC GPE, they need
to be synchronized for the boot_ec:

 1. Before registering the BIOS-provided EC event handlers in
    acpi_ec_register_query_methods(), the namespace node holding
    _Qxx methods should be located.  The real namespace PNP0C09
    device location then is apparently more trustworthy than the
    ECDT EC ID.

 2. Because of the ASUS quirks, the ECDT EC GPE is more trustworthy
    than the namespace PNP0C09 device's _GPE setting.

Use the above observations to synchronize the boot_ec settings in
acpi_ec_add().

Finally, change the order of acpi_ec_ecdt_start() and acpi_ec_add(),
called from acpi_bus_register_driver(), so as to follow the fast path
of determining the location of _Qxx.

The code did not consider the case that the channel switch counter

time event apply time.

As the specification states that in case of counter == 0 the switch
occurs at any time after the reception the frame, and for counter == 1
the switch would happens before the next TBTT, schedule the time
event immediately.

Subject: iwlwifi: distinguish different RF modules in A000 devices

Newer versions of A000 devices come with two diffenent RF modules.
The PCI_ID, the subsystem ID and the RF ID are identical in these two cases,
so we need to differentiate them by using the CSR_HW_RF_ID register-
in order to load the appropriate firmware.

Subject: iwlwifi: update channel flags parser

There are some new flags in the channel flags that we don't know
about.  Also, the "WIDE" flag is very confusing, because it actually
means 20MHz bandwidth, which is not very wide.

Add the new flags and rename the confusing one.

Subject: iwlwifi: mvm: change open and close criteria of a BA session

Tx BA session should be started according to the current throughput
without any dependence on the internal rate scaling state. The criteria
for opening a BA session will be 10 frames per second.

Sending frequent del BAs can cause inter-op issues with some APs. We'll
not close a BA session until we receive an explicit del BA from the
peer.

Subject: iwlwifi: add workaround to disable wide channels in 5GHz

The OTP in some SKUs have erroneously allowed 40MHz and 80MHz channels
in the 5.2GHz band.  The firmware has been modified to not allow this
in those SKUs, so the driver needs to do the same otherwise the
firmware will assert when we try to use it.

Subject: iwlwifi: fw: fix lar_enabled endian problem in iwl_fw_get_nvm

We read the regulatory.lar_enabled field in iwl_fw_get_nvm() and store
it in nvm->lar_enabled, taking care of endianness.  But then later we
read it again to pass the value to iwl_init_sbands() without handling
endianness.  To solve this, simply reuse nvm->lar_enabled when calling
that function.

Subject: iwlwifi: mvm: remove useless check for mvm->cfg in
 iwl_parse_nvm_section()

At this point we have already copied the cfg pointer to mvm and we
have been dereferencing this pointer many times before, so it will
never be NULL or we would have crashed.  Remove the useless check.

Subject: iwlwifi: use big-endian for the hw section of the nvm

Unlike the other sections of the NVM, the hw section is in big-endian.
To read a value from it, we had to cast it to __be16.  Fix that by
using __be16 * for the entire section.

Subject: blk-mq: Make blk_mq_reinit_tagset() calls easier to read

Since blk_mq_ops.reinit_request is only called from inside
blk_mq_reinit_tagset(), make this function pointer an argument of
blk_mq_reinit_tagset() instead of a member of struct blk_mq_ops.
This patch does not change any functionality but makes
blk_mq_reinit_tagset() calls easier to read and to analyze.

Subject: skd: Avoid that module unloading triggers a use-after-free

Since put_disk() triggers a disk_release() call and since that
last function calls blk_put_queue() if disk->queue != NULL, clear
the disk->queue pointer before calling put_disk(). This avoids
that unloading the skd kernel module triggers the following
use-after-free:

Subject: skd: Submit requests to firmware before triggering the doorbell

Ensure that the members of struct skd_msg_buf have been transferred
to the PCIe adapter before the doorbell is triggered. This patch
avoids that I/O fails sporadically and that the following error
message is reported:

(skd0:STM000196603:[0000:00:09.0]): Completion mismatch comp_id=0x0000 skreq=0x0400 new=0x0000

Subject: skd: Remove useless barrier() calls

The purpose of barrier() is to prevent reordering by the compiler.
Since the compiler does not reorder calls to non-pure functions,
remove the barrier() calls from skd_reg_{read,write}{32,64}().

Since pr_debug() is able to report file name and line number
information, remove __FILE__ and __LINE__ from the pr_debug() calls.

Subject: skd: Switch from the pr_*() to the dev_*() logging functions

Use dev_err() and dev_info() instead of pr_err() and pr_info().
Since dev_dbg() is able to report file name and line number
information, remove __FILE__ and __LINE__ from the dev_dbg() calls.
Remove the struct skd_device members and the function (skd_name())
that became superfluous due to these changes.

This patch removes the device name and serial number from log
statements. An example of the old log line format:

(skd0:STM000196603:[0000:00:09.0]): Driver state STARTING(3)=>ONLINE(4)

An example of the new log line format:

skd:0000:00:09.0: Driver state STARTING(3)=>ONLINE(4)

Due to the previous patch it is guaranteed that the FIT msg contains
at least one request after the for-loop has finished. Use this to
simplify the code.

Subject: skd: Simplify the code for allocating DMA message buffers

dma_alloc_coherent() guarantees alignment on a page boundary so
no explicit alignment is needed to align on a 64 byte boundary.

Subject: skd: Remove superfluous initializations from
 skd_isr_completion_posted()

The value of skcmp, cmp_cntxt etc. is overwritten during every
loop iteration and is not used after the loop has finished. Hence
initializing these variables outside the loop is not necessary.
This patch does not change any functionality.

Since setup_timer() invokes init_timer(), invoking init_timer()
just before setup_timer() is redundant. Hence remove the init_timer()
call.

Subject: skd: Remove superfluous occurrences of the 'volatile' keyword

mem_map[i] is accessed through readl() / writel() hence declaring
mem_map as volatile is not necessary.

Remove the volatile declarations from struct fit_completion_entry_v1
pointers and struct fit_comp_error_info since reading these structures
multiple times is safe.

Subject: skd: Convert explicit skd_request_fn() calls

This will make it easier to convert this driver to the blk-mq
approach. This patch also reduces interrupt latency by moving
skd_request_fn() calls out of the skd_isr() interrupt.

Subject: skd: Remove dead code

Removing the SG IO code also removed the code that sets
SKD_REQ_STATE_ABORTED. Hence also remove the code that checks for
this state.

Subject: skd: Initialize skd_special_context.req.n_sg to one

The debug code in skd_send_special_fitmsg() assumes that req.n_sg
represents the number of S/G descriptors. However, skd_construct()
initializes that member variable to zero. Set req.n_sg to one such
that the debugging code in skd_send_special_fitmsg() works as
expected.

Subject: skd: Enable request tags for the block layer queue

Use the request tag when allocating a skd_fitmsg_context or
skd_request_context such that the lists used to track free elements
can be eliminated. Swap the skd_end_request() and skd_release_req()
calls to avoid triggering a use-after-free. Remove
skd_fitmsg_context.state and .outstanding because FIT messages are
shared among requests and because updating a FIT message after a
request has finished whould trigger a use-after-free.

Subject: skd: Convert several per-device scalar variables into atomics

Convert the per-device scalar variables that are protected by the
queue lock into atomics such that it becomes safe to access these
variables without holding the queue lock.

Subject: skd: Introduce skd_process_request()

The only functional change in this patch is that the skd_fitmsg_context
in which requests are accumulated is changed from a local variable into
a member of struct skd_device. This patch will make the blk-mq conversion
easier.

From ca33dd92968bac6aae0ecd56bc8962b4a97492f1 Mon Sep 17 00:00:00 2001
From: Bart Van Assche <bart.vanassche@wdc.com>
Date: Thu, 17 Aug 2017 13:13:32 -0700
Subject: skd: Convert to blk-mq

Introduce a tag set and a blk_mq_ops structure. Set .cmd_size such
that struct request and struct skd_request_context are allocated
through a single allocation. Remove the skd_request_context.req
pointer. Make queue starting asynchronous such that this can occur
safely from interrupt context. Use locking to protect skdev->skmsg
and *skdev->skmsg against concurrent access from concurrent
.queue_rq() calls. Introduce the functions skd_init_request() and
skd_exit_request() to set up / clean up the per-request S/G-list.

Subject: skd: Remove skd_device.in_flight

Since skd_device.in_flight is only used to display the number of
in-flight requests in debug messages, remove that member and
introduce skd_in_flight(). That last function relies on the block
layer to determine the number of in flight requests.

Subject: skd: Reduce memory usage

Every single coherent DMA memory buffer occupies at least one page.
Reduce memory usage by switching from coherent buffers to streaming
DMA for I/O requests (struct skd_fitmsg_context) and S/G-lists
(struct fit_sg_descriptor[]).

Subject: skd: Bump driver version

Bump the driver version. Remove the build ID because build IDs do
not make sense for an upstream kernel driver. Keep the driver
version in the module information but do not report it during every
load, unload or probe.

Subject: RDMA/core: make ib_device.add method optional

ib_clients can indeed fill .add to NULL, but then they will not see
any device removal notifications. The reason is that that
ib_register_client and ib_register_device checked existence of .add
before adding the creating a corresponding client_data and adding
it to the list. Simple condition reverse fixes the issue.

Subject: cm: Don't allocate ib_cm workqueue with WQ_MEM_RECLAIM

create_workqueue always creates the workqueue with WQ_MEM_RECLAIM
and silences a flush dependency warn for WQ_LEGACY. Instead, we
want to keep the warn in case the allocator tries to flush the
cm workqueue because its very likely that cm work execution will
yield memory allocations (for example cm connection requests).

Drop the custom hook of pwm_enable() and implement pwm_apply_v1() and
pwm_apply_v2() instead.

Subject: pwm: rockchip: Move the configuration of polarity

It is usually possible to configure the polarity, cycle and duty all at
once, so that the polarity and cycle and duty are applied atomically.
Move it from rockchip_pwm_set_enable() into rockchip_pwm_config(), as
well as prepare for the next atomic update commit.

Subject: PCI: endpoint: Use of_dma_configure() to set initial DMA mask

Use of_dma_configure() to set the initial DMA mask of EPF device. This
helps to get rid of "Coherent DMA mask 0x0 (pfn 0x0-0x1) covers a smaller
range of system memory than the DMA zone pfn" warning in certain platforms
like TI's K2G resulting in coherent DMA mask not being set.

Add an API to get "pci_epf_device_id" matching the EPF name. This can be
used by the EPF driver to get the driver data corresponding to the EPF
device name.

Subject: pwm: rockchip: Add rk3328 support

The rk3328 SoC supports atomic update, we could lock the configuration
of period and duty at first, after unlock is configured, the period and
duty are effective at the same time.

If the polarity, period and duty need to be configured together,
the way for atomic update is "configure lock and old polarity" ->
"configure period and duty" -> "configure unlock and new polarity".

Fixes a false positive from might_sleep(). The reservation object is freshly
initialized, so nobody else can hold the mutex but the function is
called from atomic context.

v2: Correctly invert the check as well.

Subject: s390/qeth: split L2 xmit paths

l2_hard_start_xmit() actually doesn't contain much shared code,
and having device-specific paths makes isolated changes a lot easier.
So split it into three routines for IQD, OSN and OSD/OSM/OSX.

No functional change.

Subject: s390/qeth: pass full data length to l2_fill_header()

For IQD we already need to fix up the qeth_hdr's length field, and
future changes will require more flexibility for OSA as well. The
device-specific path knows best what header length it requires, so just
pass it from there.
While at it, remove the unused qeth_card parameter.

No functional change.

Subject: s390/qeth: pass TSO header length to fill_buffer()

The TSO code already calculates the length of its header element,
no need to duplicate this in the low-level code again.

Use this opportunity to make hd_len unsigned, and for TSO match
its calculation to what tso_fill_header() does.

No functional change.

Subject: s390/qeth: pass TSO data offset to fill_buffer()

For TSO we need to skip the skb's qeth/IP/TCP headers when mapping
it into buffer elements. Instead of (mis)using skb_pull(), pass a
corresponding offset to fill_buffer() like we already do for IQDs.

No actual change in the resulting TSO buffers.

Subject: s390/qeth: pass full IQD header length to fill_buffer()

This is a prerequisite for unifying the code to build header elements.
The TSO header has a different size, so we can no longer rely on implicitly
adding the size of a normal qeth_hdr.

No functional change.

Subject: s390/qeth: unify code to build header elements

After plenty of refactoring, use hd_len as single indication that
the skb needs a dedicated header element.

This preserves existing behaviour for TSO, as 'hdr' always points
to skb->data.

Subject: s390/qeth: use skb_cow_head() for L2 OSA xmit

Taking a full copy via skb_realloc_headroom() on every xmit is overkill
and wastes CPU time; all we actually need is to push on the qeth_hdr.
So rework the L2 OSA TX path to avoid the copy.
Minor complications arise because struct qeth_hdr must not cross a page
boundary. So add a new helper qeth_push_hdr() that catches this, and
falls back to the hdr cache that we already use for IQDs.

This change uncovered that qeth's TX completion takes rather long.
Now that we no longer free the original skb straight away and thus call
skb->destructor later than before, throughput regresses significantly.
For now, restore old behaviour by adding an explicit skb_orphan(),
and a big TODO to improve the TX completion time.

Subject: nfp: fix infinite loop on umapping cleanup

The while loop that performs the dma page unmapping never decrements
index counter f and hence loops forever. Fix this with a pre-decrement
on f.

Subject: net/sched: Fix the logic error to decide the ingress qdisc

The offending commit used a newly added helper function.
But the logic is wrong. Without this fix, the affected NICs
can't do HW offload. Error -EOPNOTSUPP will be returned directly.

Subject: net: hns3: Fixes the missing u64_stats_fetch_begin_irq in 64-bit
 stats fetch

This patch fixes the missing u64_stats_fetch_begin_irq() while trying to
atomically do 64-bit RX/TX fetch. We did not get any error during test
as our SoC is 64-bit so all of these seq/lock operations results in NOOP.

As such, this seq lock supports has been added for the sake of completion
if this code ever runs on 32-bit platform and we are trying to do 64-bit
stats fetch.

hip08 SoC")

Subject: video/console: Add dmi quirk table for x86 systems which need fbcon
 rotation

Some x86 clamshell design devices use portrait tablet screens and a
display engine which cannot rotate in hardware, so we need to rotate
the fbcon to compensate.

This commit adds a DMI based quirk table which is initially populated with
4 such devices: The Asus T100HA, GPD Pocket, the GPD win and the I.T.Works
TW891, so that the console comes up in the right orientation on these
devices OOTB.

Unfortunately these (cheap) devices also typically have quite generic DMI
data, so we match on a combination of DMI data, screen resolution and a
list of known BIOS dates to avoid false positives.

This check is needed in the case where the width of the framebuffer
is not a multiple of 8 pixels. For example, LEGO MINDSTORMS EV3 has
a 178x128 1bpp display.

Subject: fbcon: add fbcon=margin:<color> command line option

This adds a new command line option to select the fbcon margin color.

The motivation for this is screens where black does not blend into the
physical surroundings of the screen. For example, using an LCD (not the
backlit kind), white text on a black background is hard to read, so
inverting the colors is preferred. However, when you do this, most of the
screen is filled with white but the margins are still filled with black.
This makes a big, black, backwards 'L' on the screen. By setting
fbcon=margin:7, the margins will be filled with white and the LCD looks as
expected.

Subject: video: fbdev: add const to bin_attribute structures

Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file or
device_{remove/create}_bin_file. The corresponding arguments are of
type const, so declare the structures to be const.

vt8623_timing_regs is only passed as the first argument to
svga_check_timings and as the second argument to svga_set_timings,
both of which are const.  So make vt8623_timing_regs const also.

Subject: PCI/IB: add support for pci driver attribute groups

Some drivers (specifically the nes IB driver), want to create a lot of
sysfs driver attributes.  Instead of open-coding the creation and
removal of these files (and getting it wrong btw), it's a better idea to
let the driver core handle all of this logic for us.

So add a new field to the pci driver structure, **groups, that allows
pci drivers to specify an attribute group list it wishes to have created
when it is registered with the driver core.

Big bonus is now the driver doesn't race with userspace when the sysfs
files are created vs. when the kobject is announced, so any script/tool
that actually wanted to use these files will not have to poll waiting
for them to show up.

Subject: i40iw: Fixes for static checker warnings

Remove NULL check for cm_node->listener in i40iw_accept
as listener is always present at this point.

Remove the check for cm_node->accept_pend and related code
in i40iw_cm_event_connected as the cm_node in this context
is only pertinent to active node and cm_node->accept_pend
is always 0.

This fixes the following smatch warnings,

drivers/infiniband/hw/i40iw/i40iw_cm.c:3691 i40iw_accept()
error: we previously assumed 'cm_node->listener' could be null

drivers/infiniband/hw/i40iw/i40iw_cm.c:4061 i40iw_cm_event_connected()
error: we previously assumed 'cm_node->listener' could be null

From 6a5df91baf2528e584bf4493c30bbafe2db74c9e Mon Sep 17 00:00:00 2001
From: Selvin Xavier <selvin.xavier@broadcom.com>
Date: Wed, 2 Aug 2017 01:46:18 -0700
Subject: RDMA/bnxt_re: Allocate multiple notification queues

Enables multiple Interrupt vectors. Driver is requesting the max
MSIX vectors based on the number of online  cpus and creates upto
9 MSIx vectors (1 for control path and 8 for data path).
A tasklet is created for each of these vectors. NQs are assigned
to CQs in round robin fashion.
This patch also adds IRQ affinity hint for the MSIX vector of each NQ.

Subject: tun: handle register_netdevice() failures properly

syzkaller reported a double free [1], caused by the fact
that tun driver was not updated properly when priv_destructor
was added.

When/if register_netdevice() fails, priv_destructor() must have been
called already.

Subject: staging: vboxvideo: select DRM_TTM

vboxvideo code uses various ttm_* functions, so it needs
"drivers/gpu/drm/ttm/*" to be built. In order to build these objects
select DRM_TTM.

This commit fixes "ttm_*" undefined build errors.

Subject: staging: vboxvideo: switch to drm_*{get,put} helpers

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() adn should not be
used by new code. So convert all users of compatibility functions to use
the new APIs.

Subject: staging: pi433: replace INVALID_PARAM macro with inline code

The following macro:
\#define INVALID_PARAM
	{ \
                dev_dbg(&spi->dev, "set: illegal input param"); \
                return -EINVAL; \
        }
affects control flow by having return statement. This is against
Linux Kernel Coding Style and should be avoided and therefore
this macro is replaced by inline code.

Additionally following 3 minor issues:

ERROR: code indent should use tabs where possible
ERROR: spaces required around that '!=' (ctx:VxV)
ERROR: space prohibited before that close parenthesis ')'

were fiexed inline.

Subject: staging: typec: tcpm: Report role swap complete after entering READY
 state

Role swap requests fail unless the current role is either SRC_READY or
SNK_READY. This works fine for VCONN and data role swaps, where we
immediately enter READY state after reporting a successful role swap
to user space. However, on power role changes, the role swap is currently
reported as successful while power negotiation is still in process.
User space does not know this, and may request another role swap
immediately after a power role swap is reported to be complete.
This second role swap will fail with -EAGAIN.

To fix the problem, report role swap completion after power negotiation
is complete and the state machine enters SRC_READY or SNK_READY state.
This is better anyway since it captures errors due to failed power
negotiations. It also simplifies the code since the number of calls
needed to report successful role swaps is reduced.

Subject: staging: typec: tcpm: Set default state after error recovery based on
 port type

While exiting ERROR_RECOVERY, choose default state based on the port
type instead of current power role.

Quoting from specification:

4.5.2.2.2 ErrorRecovery State
This state appears in Figure 4-12, Figure 4-13, Figure 4-14, Figure 4-15,
Figure 4-16 and Figure 4-17.
The ErrorRecovery state is where the port removes the terminations from
the CC1 and CC2 pins for tErrorRecovery followed by transitioning to the
appropriate Unattached.SNK or Unattached.SRC state based on port type.
This is the equivalent of forcing a detach event and looking for a new
attach.

Subject: staging: typec: tcpm: Select default state based on port type

tcpm_default_state wasn't considering the port type when determining the
default role. This change makes tcpm_default_state to consider port type
as well.

tcpm_default_state would return the following based on the port type:
TYPEC_PORT_UFP - SNK_UNATTACHED
TYPEC_PORT_DFP - SRC_UNATTACHED
TYPEC_PORT_DRP - based on the preferred_role setting

Subject: staging: typec: tcpm: Add timeout when waiting for role swap
 completion

The Type-C protocol manager state machine could fail, which might result
in role swap requests from user space to hang forever. Add a generous
timeout when waiting for role swaps to complete to avoid this situation.

Subject: staging: typec: tcpm: Improve role swap with non PD capable partners

If the partner is not PD capable, we can not use a power role set request
to swap roles. Use the data role set request instead.

Also, if a partner is not PD capable, it does not really make sense to send
a PD message to trigger a role swap. On top of that, we should really wait
for the attempted role change to complete. Otherwise, it may well be that
user space requests another role change immediately afterwards which will
fail because the port is not yet in ready state.

Trigger the role swap from data role change requests and introduce new
state PORT_RESET and use it to solve the problem. This new state is
mostly identical to ERROR_RECOVERY, only it does not cause a pending
role change to fail. Use this new state also when initializing the driver.
Rename ERROR_RECOVERY_WAIT_OFF to PORT_RESET_WAIT_OFF to better reflect
its new meaning.

At present, TCPM does not take into account the actual resistor
value presented in the CC line and therefore reports TYPEC_PWR_MODE_USB
irrespective of the power_op_mode it is in.
This patch makes TCPM consider the actual value of Rp.

Fixed a potential memory leak inside skb_ether_to_p80211()
	When the wep_encrypt() fails  the code return 2 directly
	Which causes the p80211_wep->data dangling

Add a kfree statement to reclaim that memory allocated

Subject: staging: most: hdm-dim2: fix error return code in dim2_probe()

platform_get_irq() returns an error code, but the dim2_hdm driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Also, notice that platform_get_irq() no longer returns 0 on error:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

Subject: staging: speakup: fix async usb removal

When an external USB synth is unplugged while the module is loaded, we
get a null pointer deref. This is because the tty disappears while
speakup tries to use to to communicate with the synth. This patch fixes
it by checking tty for null before using it. Since tty can become null
between the check and its usage, a mutex is introduced. tty usage is
now surrounded by the mutex, as is the code in speakup_ldisc_close which
sets the tty to null. The mutex also serialises calls to tty from
speakup code.

In case of tty being null, this sets synth->alive to zero and restarts
ttys in case they were stopped by speakup.

Subject: staging: typec: tcpm: explicit_contract is always established

While in SNK_READY state, the explicit_contract seems to be
set to true irrespective of whether an explicit contract
was established for the current connection. TCPM also seems
to report the pwr_opmode as TYPEC_PWR_MODE_PD always once
the port gets into SNK_READY state. This isn't completely
true as port gets into the SNK_READY state for non-pd
type-c ports as well.

This patch sets the explicit_contract flag only when
the PS_READY message is received and the vbus has been
detected by the port controller.

Subject: platform/x86: thinkpad_acpi: Fix warning about deprecated
 hwmon_device_register

Use hwmon_device_register_with_groups instead of deprecated
hwmon_device_register and fix a dmesg warning.

This patch however changes the userspace API.
hwmon_device_register_with_groups takes `hwmon' name as an argument and
creates a name file in the `hwmon' device, not in the `platform_device'.
This allows us to remove custom `name' device attribute, but in order to
make lm-sensors happy we also have to move fans and thermal attributes
to the `hwmon' device.

Even though this patch changes userspace API, it's still compatible with
the lm-sensors. Starting with lm-sensors 3.0 (circa 2007), it looks at
both hwmon and the backing device for the name and other attributes.

itself, return the root port rather than NULL.

This effectively reverts commit 0e405232871d6 ("PCI: fix oops when
try to find Root Port for a PCI device") which added an extra check
that would now be redundant.

Subject: net/mlx4_core: Enable 4K UAR if SRIOV module parameter is not enabled

enable_4k_uar module parameter was added in patch cited below to
address the backward compatibility issue in SRIOV when the VM has
system's PAGE_SIZE uar implementation and the Hypervisor has 4k uar
implementation.

The above compatibility issue does not exist in the non SRIOV case.
In this patch, we always enable 4k uar implementation if SRIOV
is not enabled on mlx4's supported cards.

Currently, if vport is zero then then an uninialized return status
in err is returned.  Since the only return status at the end of the
function esw_add_uc_addr is zero for the current set of return paths
we may as well just return 0 rather than err to fix this issue.

Subject: amd-xgbe: Be sure driver shuts down cleanly on module removal

Sometimes when the driver is being unloaded while the devices are still
up the driver can issue errors.  This is based on timing and the double
invocation of some routines.  The phy_exit() call needs to be run after
the network device has been closed and unregistered from the system.
Also, the phy_exit() does not need to invoke phy_stop() since that will
be called as part of the device closing, so remove that call.

Subject: amd-xgbe: Add support to handle device renaming

Many of the names used by the driver are based upon the name of the device
found during device probe.  Move the formatting of the names into the
device open function so that any renaming that occurs before the device is
brought up will be accounted for.  This also means moving the creation of
some named workqueues into the device open path.

Add support to register for net events so that if a device is renamed
the corresponding debugfs directory can be renamed.

Subject: amd-xgbe: Optimize DMA channel interrupt enablement

Currently whenever the driver needs to enable or disable interrupts for
a DMA channel it reads the interrupt enable register (IER), updates the
value and then writes the new value back to the IER. Since the hardware
does not change the IER, software can track this value and elimiate the
need to read it each time.

Add the IER value to the channel related data structure and use that as
the base for enabling and disabling interrupts, thus removing the need
for the MMIO read.

Subject: amd-xgbe: Add support for VXLAN offload capabilities

The hardware has the capability to perform checksum offload support
(both Tx and Rx) and TSO support for VXLAN packets. Add the support
required to enable this.

The hardware can only support a single VXLAN port for offload. If more
than one VXLAN port is added then the offload capabilities have to be
disabled and can no longer be advertised.

Subject: Input: trackpoint - add new trackpoint firmware ID

Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits
are indicated as TP. Change the constant to bitwise values.

This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead
of it being identified as "PS/2 Generic Mouse".

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Elan touchpads on Asus ROG G752xx series laptops have 2 physical buttons.
Luckily we can query the touchpad to see if it is a clickpad variant and
adjust the behavior accordingly.

Subject: staging: lustre: mgc: fix potential use after free in error path

The config_log_add() function first calls config_log_put() with the
variable 'cld' and then jumps to label 'out_cld', which will call
the same function with the same 'cld' variable. However, at this
point, 'cld' might have been already freed by the first invocation
of config_log_put(). Even if we remove the invocation at that point,
we will still get into trouble. This is because, in the error path,
just below the label 'out_cld', we try to put 'params_cls' and
'sptlrpc_cld', which might also have been freed by config_log_put().

The point is that, config_llog_data::cld_sptlrpc and
config_llog_data::cld_params members are assigned at the beginning
of this function.

To avoid this, do not call config_log_put() inside the else block,
immediately jump to 'out_cld' instead. Moreover, remove assignments
to config_llog_data::cld_sptlrpc and config_llog_data::cld_params at
the beginning, since we already assign them below in the function
with 'cld_lock' held.

As an additional benefit, code size gets smaller.

Subject: PCI: Avoid race while enabling upstream bridges

When we enable a device, we first enable any upstream bridges.  If a bridge
has multiple downstream devices and we enable them simultaneously, the race
to enable the upstream bridge may cause problems.  Consider this hierarchy:

  bridge A --+-- device B
             +-- device C

If drivers for B and C call pci_enable_device() simultaneously, both will
attempt to enable A, which involves setting PCI_COMMAND_MASTER via
pci_set_master() and PCI_COMMAND_MEMORY via pci_enable_resources().

In the following sequence, B's update to set A's PCI_COMMAND_MEMORY is
lost, and neither B nor C will work correctly:

      B                                C
  pci_set_master(A)
    cmd = read(A, PCI_COMMAND)
    cmd |= PCI_COMMAND_MASTER
                                   pci_set_master(A)
                                     cmd = read(A, PCI_COMMAND)
                                     cmd |= PCI_COMMAND_MASTER
    write(A, PCI_COMMAND, cmd)
  pci_enable_device(A)
    pci_enable_resources(A)
      cmd = read(A, PCI_COMMAND)
      cmd |= PCI_COMMAND_MEMORY
      write(A, PCI_COMMAND, cmd)
                                     write(A, PCI_COMMAND, cmd)

Avoid this race by holding a new pci_bridge_mutex while enabling a bridge.
This ensures that both PCI_COMMAND_MASTER and PCI_COMMAND_MEMORY will be
updated before another thread can start enabling the bridge.

Note that although pci_enable_bridge() is recursive, it enables any
upstream bridges *before* acquiring the mutex.  When it acquires the mutex
and calls pci_set_master() and pci_enable_device(), any upstream bridges
have already been enabled so pci_enable_device() will not deadlock by
calling pci_enable_bridge() again.

Start linking ethtool ops to representors.  Begin by adding
a separate ops structure and providing link state.  Next
patches will convert appropriate functions to only use nfp_port,
which will make them reusable on representors.

Extend representors' ethtool ops to show basic info like firmware
version, driver version, and driver name.

While at it don't set drvinfo.n_stats and drvinfo.regdump_len,
core will invoke appropriate handlers to get those.

A helper is added to turn a netdev into nfp_app for convenience.

Subject: nfp: allow retreiving management FW logs on representors

Users should be able to dump the management FW logs on any
of the driver's netdevs.  Make the code only depend on the
nfp_app and share it between vNICs and representors.

Storing the dump flag is simply dropped for now, since we
only support the argument being set to 0.

Subject: nfp: don't report standard netdev statistics in ethtool

We have been recently called out as a bad example for reporting
standard netdev statistics as part of ethtool.  Fix that :)

Removing standard statistics allows us to simplify the structure
holding definitions since we no longer have to mux different types
of statistics.

Subject: nfp: split software and hardware vNIC statistics

In preparation for reporting vNIC HW stats on representors
split handling of the SW and HW stats in ethtool -S.
Representors don't have SW stats (since vNIC is assigned
to the VM).

Remove the questionable defines which assume nn variable
exists in the scope.

Store pointer to device memory containing MAC statistics
in nfp_port.  This simplifies representor code and will
be used to dump those statistics in ethtool as well.

Subject: nfp: report MAC statistics in ethtool

Add reporting of MAC statistics in ethtool.  MAC statistics
are read out from the MAC IP and accumulated by application
FW, therefore their presence depends on the application FW.

Add missing defines and string names for the statistics and
dump them in ethtool -S.

Subject: nfp: add pointer to vNIC config memory to nfp_port structure

Simplify the statistics handling code by keeping pointer to vNIC's
config memory in nfp_port.  Note that this is referring to the
representor side of vNICs, vNIC side has the pointer in nfp_net.

Subject: nfp: add ethtool statistics for representors

Representors may be associated with both VFs or more importantly
with physical ports.  Allow vNIC and MAC statistics to be read
with ethtool -S on representors.  In case of vNICs we reuse
the vNIC statistic helper, we just need to swap RX and TX to
give statistics the "switch perspective."

Data and control vNICs currently use the same area name and
error message.  This could lead to confusion.  Make sure
the error message says "ctrl" in case of control and the
data area is called "nfp.bar0".

Subject: nfp: don't reuse pointers in ring dumping

We were reusing skb pointer when reading page frag, since ring
entries contain a union of a skb and frag pointer.  This can
be confusing to people reading the code.  Refactor the code
to read frag pointer directly.

Subject: EDAC, pnd2: Conditionally unhide/hide the P2SB PCI device to read BAR

On Deverton server, the P2SB PCI device (DEV:1F, FUN:1) is used by multiple
device drivers.

If it's hidden by some device driver (e.g. with the i801 I2C driver,
the commit

  9424693035a5 ("i2c: i801: Create iTCO device on newer Intel PCHs")

unconditionally hid the P2SB PCI device wrongly) it will make the
pnd2_edac driver read out an invalid BAR value of 0xffffffff and then
fail on ioremap().

Therefore, store the presence state of P2SB PCI device before unhiding
it for reading BAR and restore the presence state after reading BAR.

Subject: irqchip/gic-v3-its: Properly handle command queue wrapping

wait_for_range_completion() is nicely busted when handling
wrapping of the command queue, leading to an early exit
instead of waiting for the command to have been executed.

Fortunately, the impact is pretty minor, as it only impair
the detection of an ITS that doesn't make any forward progress
for a whole second. And an ITS should *never* lock up.

Subject: phy: qcom-qmp: Fix phy pipe clock name

Presently, the phy pipe clock's name is assumed to be either
usb3_phy_pipe_clk_src or pcie_XX_pipe_clk_src (where XX is the
phy lane's number). However, this will not work if an SoC has
more than one instance of the phy. Hence, instead of assuming
the name of the clock, fetch it from the DT.

Subject: phy: ti-pipe3: Use TRM recommended settings for SATA DPLL

The AM572x Technical Reference Manual, SPRUHZ6H,
Revised November 2016 [1], shows recommended settings for the
SATA DPLL in Table 26-8. DPLL CLKDCOLDO Recommended Settings.

Use those settings in the driver. The TRM does not show
a value for 20MHz SYS_CLK so we use something close to the
26MHz setting.

From cd4ec4b03dc15b164390c9d3e02e64935c3dd369 Mon Sep 17 00:00:00 2001
From: Chunfeng Yun <chunfeng.yun@mediatek.com>

Subject: phy: phy-mt65xx-usb3: add mediatek directory and rename file

The driver is actually for T-PHY which supports USB3.0, PCIe and SATA,
and supports more SoCs now, but not just only for series of mt65xx SoCs,
so the name of file, data struct, functions etc with 'mt65xx' may cause
misunderstanding when new SoCs are supported. Here rename them to reflect
the real functions and also enhance readability.

And also update MAINTAINERS file to reflect the correct driver

Subject: phy: ralink-usb: add driver for Mediatek/Ralink

Add a driver to setup the USB phy on Mediatek/Ralink SoCs.
The driver sets up power and host mode, but also needs to
configure PHY registers for the MT7628 and MT7688.

Subject: net/mlx5e: Send PAOS command on interface up/down

Upon interface up/down, driver will send PAOS (Ports Administrative and
Operational Status Register) in order to inform the Firmware on the
desired status of the port by the driver.

Since now we might change physical link status on mlx5e_open/close,
logical VF representor should not use mlx5e_open/close ndos as is, and
should call the logical version mlx5e_open/closed_locked.

Printing an enhanced IPoIB device information using
"ethtool -i DEVNAME", prints the low level driver name: mlx5_core.
This commit changes the name to mlx5_core [ib_ipoib], to include the
ipoib device driver infromation.

From: Eran Ben Elisha <eranbe@mellanox.com>

Subject: net/mlx5e: Add outbound PCI buffer overflow counter

Add outbound_pci_buffer_overflow to ethtool output for monitoring the
number of packets that were dropped due to lack of PCIe buffers on
receive path from NIC port toward the host(s).

This counter is valid only in case that tx_overflow_buffer_pkt is
supported in MCAM enhanced features.

Subject: iio: hid-sensor-trigger: Fix the race with user space powering up
 sensors

It has been reported for a while that with iio-sensor-proxy service the
rotation only works after one suspend/resume cycle. This required a wait
in the systemd unit file to avoid race. I found a Yoga 900 where I could
reproduce this.

The problem scenerio is:
- During sensor driver init, enable run time PM and also set a
  auto-suspend for 3 seconds.
	This result in one runtime resume. But there is a check to avoid
a powerup in this sequence, but rpm is active
- User space iio-sensor-proxy tries to power up the sensor. Since rpm is
  active it will simply return. But sensors were not actually
powered up in the prior sequence, so actaully the sensors will not work
- After 3 seconds the auto suspend kicks

If we add a wait in systemd service file to fire iio-sensor-proxy after
3 seconds, then now everything will work as the runtime resume will
actually powerup the sensor as this is a user request.

To avoid this:
- Remove the check to match user requested state, this will cause a
  brief powerup, but if the iio-sensor-proxy starts immediately it will
still work as the sensors are ON.
- Also move the autosuspend delay to place when user requested turn off
  of sensors, like after user finished raw read or buffer disable

Subject: iio: adc: ti-ads1015: fix incorrect data rate setting update

The ti-ads1015 driver has eight iio voltage channels and each iio channel
can hold own sampling frequency information.

The ADS1015 device only have a single config register which contains an
input multiplexer selection, PGA and data rate settings.  So the driver
should load the correct settings when the input multiplexer selection is
changed.

However, regardless of which channlel is currently selected, changing any
iio channel's sampling frequency information immediately overwrites the
current data rate setting in the config register.

It breaks the current data rate setting if the different channel's sampling
frequency information is changed because the data rate setting is not
reloaded when the input multiplexer is switched.

This removes the unexpected config register update and correctly load the
data rate setting before getting adc result.

Subject: iio: adc: ti-ads1015: fix scale information for ADS1115

The ti-ads1015 driver supports ADS1015 and ADS1115 devices.  The same
scale information is used for both devices in this driver, however they
have actually different values and the ADS1115's one is not correct.

These devices have the same full-scale input voltage range for each PGA
selection.  So instead of adding another hardcoded scale information,
compute a correct scale on demand from each device's resolution.

Subject: iio: adc: ti-ads1015: enable conversion when CONFIG_PM is not set

The ADS1015 device have two operating modes, continuous conversion mode
and single-shot mode.  This driver assumes that the continuous conversion
mode is selected by runtime resume callback when the ADC result is
requested.

If CONFIG_PM is disabled, the device is always in the default single-shot
mode and no one begins a single conversion.  So the conversion register
doesn't contain valid ADC result.  Fix it by changing the continuous mode
in probe function.

Subject: iio: adc: ti-ads1015: avoid getting stale result after runtime resume

This driver assumes that the device is operating in the continuous
conversion mode which performs the conversion continuously.  So this driver
doesn't insert a wait time before reading the conversion register if the
configuration is not changed from a previous request.

This assumption is broken if the device is runtime suspended and entered
a power-down state.  The forthcoming request causes reading a stale result
from the conversion register as the device is runtime resumed just before.

Fix it by adding a flag to detect that condition and insert a necessary
wait time.

 callbacks

pm_runtime_get_sync() and pm_runtime_put_autosuspend() return 0 on
success, 1 if the device's runtime PM status was already requested status
or error code on failure.  So a positive return value doesn't indicate an
error condition.

However, any non-zero return values from buffer preenable and postdisable
callbacks are recognized as an error and this driver reuses the return
value from pm_runtime_get_sync() and pm_runtime_put_autosuspend() in
these callbacks.  This change fixes the false error detections.

 conversion

This driver assumes that the device is operating in the continuous
conversion mode which performs the conversion continuously.  So this driver
inserts a wait time before reading the conversion register if the
configuration is changed from a previous request.

Currently, the wait time is only the period required for a single
conversion that is calculated as the reciprocal of the sampling frequency.
However we also need to wait for the the previous conversion to complete.
Otherwise we probably get the conversion result for the previous
configuration when the sampling frequency is lower.

Subject: iio: adc: ti-ads1015: remove unnecessary config register update

The ti-ads1015 driver has eight iio voltage channels and each iio channel
can hold own scale information.

The ADS1015 device only have a single config register which contains an
input multiplexer selection, PGA and data rate settings.  So the driver
should load the correct settings when the input multiplexer selection is
changed.

However, regardless of which channlel is currently selected, changing any
iio channel's scale information immediately overwrites the current PGA
setting in the config register.

It is harmless because the correct PGA settings are reloaded just before
getting adc result anyway.  But it is unnecessary register update and
should be removed.

Subject: iio: adc: ti-ads1015: use devm_iio_triggered_buffer_setup

Use devm_iio_triggered_buffer_setup to simplify the error path in the
probe() and remove() function.

This changes the remove order, but the end result of remove function
actually does the reverse of probe.

Subject: iio: adc: ti-ads1015: use iio_device_claim_direct_mode()

While the iio buffer for the ti-ads1015 driver is enabled, reading the
raw ADC channel data is restricted.  We usually use the
iio_device_claim_direct_mode()/iio_device_release_direct_mode() pair for
that.

This change consequently reverses the locking order for the driver's
private lock and indio_dev->mlock which acquired by
iio_device_claim_direct_mode() internally. But it's safe because there is
no other dependency between these locks.

Subject: iio: adc: ti-ads1015: add threshold event support

The ADS1015 device provides programmable comparator that can issue an
interrupt on the ALERT pin.  This change adds the iio threshold event
support for that feature.

The ADS1015 device only have a single config register which contains an
input multiplexer selection, comparator settings, and etc.  So only a
single event channel can be enabled at a time.  Also enabling both buffer
and event are prohibited for simplicity.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: Input: soc_button_array - silence -ENOENT error on Dell XPS13 9365

The Dell XPS13 9365 has an INT33D2 ACPI node with no GPIOs, causing
the following error in dmesg:

[    7.172275] soc_button_array: probe of INT33D2:00 failed with error -2

This commit silences this, by returning -ENODEV when there are no GPIOs.

Subject: staging: lustre: lustre: Off by two in lmv_fid2path()

We want to concatonate join string one, a '/' character, string two and
then a NUL terminator.  The destination buffer holds ori_gf->gf_pathlen
characters.  The strlen() function returns the number of characters not
counting the NUL terminator.  So we should be adding two extra spaces,
one for the foward slash and one for the NUL.

The mask of sns_key_info1 suggests the upper nybble is being extracted
however the following shift of 8 bits is too large and always results in
0.  Fix this by shifting only by 4 bits to correctly get the upper nybble.

Subject: staging: r8822be: Add existing rtlwifi and rtl_pci parts for new
 driver

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

This commit copies the code that currently constitutes the rtlwifi and
rtl_pci mini drivers. This material is copied into staging to prevent
any undo interaction between the existing drivers and this new one.
The only changes in this code are the removal of all export statements,
and the fixing of some checkpatch messages. The latter will be backported
into the wireless tree.

From fbdc6ba8eed9090e4ee4e070c70b18f247deaeac Mon Sep 17 00:00:00 2001
From: Larry Finger <Larry.Finger@lwfinger.net>
Date: Thu, 17 Aug 2017 12:46:46 -0500
Subject: staging: r8822be: Copy existing btcoexist code into staging

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

This commit copies the existing routines from .../rtlwifi/btcoexist/
into staging. There are no changes other than removing all EXPORT
statements, and the fixing of checkpatch messages. The latter will
be backported to the wireless tree.

Subject: staging: r8822be: Add r8822be btcoexist routines to staging

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

This commit adds the routines needed for BT coexistence with the
new driver.

Subject: staging: r8822be: Add code for halmac sub-driver

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

New Realtek devices implement a common sub-driver to control the MAC
layer. The RTL8822BE is the first of these devices, thus its introduction
involves some extra code. In the wireless tree, this will be a separate
module; however, it is compiled into the 8822be driver here.

Subject: staging: r8822be: Add phydm mini driver

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

New Realtek wireless devices have a new method for PHY control and
dynamic management. The RTL8822BE is the first of these devices, thus
there is additional code required.

In the final version, this code will be a separate module; however,
it is combined with the r8822be driver to minimize the interference
with the drivers in the wireless tree.

From 7e5b796cde7ed4f4edc242549b9585a78dac978d Mon Sep 17 00:00:00 2001
From: Ping-Ke Shih <pkshih@realtek.com>
Date: Thu, 17 Aug 2017 12:46:50 -0500
Subject: staging: r8822be: Add the driver code

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

This commit adds the code for the new r8822be driver.

From 5b5ab4cb5cda824ef59e0511ac5d585f35f1a1a6 Mon Sep 17 00:00:00 2001
From: Larry Finger <Larry.Finger@lwfinger.net>

Subject: staging: r8822be: Add Makefiles and Kconfig for new driver

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

This commit enables building of the new driver. For this version, all
routines are built into a single module r8822be. When this driver is
moved to the wireless tree, halmac, phydm, and rtl8822be will become
new modules.

Subject: ieee802154: ca8210: Fix a potential NULL pointer dereference

'spi' is known to be NULL, so we dereference a NULL pointer here.
Use 'pr_crit()' instead of 'dev_crit()' to report the message.

Subject: Kbuild: use -fshort-wchar globally

Commit 971a69db7dc0 ("Xen: don't warn about 2-byte wchar_t in efi")
added the --no-wchar-size-warning to the Makefile to avoid this
harmless warning:

arm-linux-gnueabi-ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail

Changing kbuild to use thin archives instead of recursive linking
unfortunately brings the same warning back during the final link.

The kernel does not use wchar_t string literals at this point, and
xen does not use wchar_t at all (only efi_char16_t), so the flag
has no effect, but as pointed out by Jan Beulich, adding a wchar_t
string literal would be bad here.

Since wchar_t is always defined as u16, independent of the toolchain
default, always passing -fshort-wchar is correct and lets us
remove the Xen specific hack along with fixing the warning.

Subject: cxgb4/cxgbvf: Handle 32-bit fw port capabilities

Implement new 32-bit Firmware Port Capabilities in order to
handle new speeds which couldn't be represented in the old 16-bit
Firmware Port Capabilities values.

Based on the original work of Casey Leedom <leedom@chelsio.com>

Subject: net: ibm: emac: Fix some error handling path in 'emac_probe()'

If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is
known to be 0 at this point.
So return -ENODEV instead in the first case and use 'of_iomap()' instead of
the equivalent 'of_address_to_resource()/ioremap()' combinaison in the 2nd
case.

Doing so, the 'rsrc_regs' field of the 'emac_instance struct' becomes
redundant and is removed.

While at it, turn a 'err != 0' test into an equivalent 'err' to be more
consistent.

Subject: pwm: tiecap: Set driver data before runtime PM enable

Runtime PM callbacks can be run right after runtime PM is enabled, so
make sure to set the driver data before that. This is unlikely to ever
happen with the current driver, but it doesn't hurt to follow best
practices anyway.

Subject: pwm: tiehrpwm: Set driver data before runtime PM enable

Runtime PM callbacks can be run right after runtime PM is enabled, so
make sure to set the driver data before that. This is unlikely to ever
happen with the current driver, but it doesn't hurt to follow best
practices anyway.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting

to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

Date: Fri, 18 Aug 2017 20:49:34 +0100
Subject: efi/arm: Don't mark ACPI reclaim memory as MEMBLOCK_NOMAP

On ARM, regions of memory that are described by UEFI as having special
significance to the firmware itself are omitted from the linear mapping.
This is necessary since we cannot guarantee that alternate mappings of
the same physical region will use attributes that are compatible with
the ones we use for the linear mapping, and aliases with mismatched
attributes are prohibited by the architecture.

The above does not apply to ACPI reclaim regions: such regions have no
special significance to the firmware, and it is up to the OS to decide
whether or not to preserve them after it has consumed their contents,
and for how long, after which time the OS can use the memory in any way
it likes. In the Linux case, such regions are preserved indefinitely,
and are simply treated the same way as other 'reserved' memory types.

Punching holes into the linear mapping causes page table fragmentation,
which increases TLB pressure, and so we should avoid doing so if we can.
So add a special case for regions of type EFI_ACPI_RECLAIM_MEMORY, and
memblock_reserve() them instead of marking them MEMBLOCK_NOMAP.

Subject: efi/libstub/arm64: Set -fpie when building the EFI stub

Clang may emit absolute symbol references when building in non-PIC mode,
even when using the default 'small' code model, which is already mostly
position independent to begin with, due to its use of adrp/add pairs
that have a relative range of +/- 4 GB. The remedy is to pass the -fpie
flag, which can be done safely now that the code has been updated to avoid
GOT indirections (which may be emitted due to the compiler assuming that
the PIC/PIE code may end up in a shared library that is subject to ELF
symbol preemption)

Passing -fpie when building code that needs to execute at an a priori
unknown offset is arguably an improvement in any case, and given that
the recent visibility changes allow the PIC build to pass with GCC as
well, let's add -fpie for all arm64 builds rather than only for Clang.

Subject: efi/arm/arm64: Add missing assignment of efi.config_table

The ARM EFI init code never assigns the config_table member of the
efi struct, which means the sysfs device node is missing, and other
in-kernel users will not work correctly. So add the missing assignment.

Note that, for now, the runtime and fw_vendor members are still
omitted. This is deliberate: exposing physical addresses via sysfs nodes
encourages behavior that we would like to avoid on ARM (given how it is
more finicky about using correct memory attributes when mapping memory
in userland that may be mapped by the kernel already as well).

Subject: efi/reboot: Fall back to original power-off method if
 EFI_RESET_SHUTDOWN returns

Commit:

  44be28e9dd98 ("x86/reboot: Add EFI reboot quirk for ACPI Hardware Reduced flag")

sets pm_power_off to efi_power_off() when the acpi_gbl_reduced_hardware
flag is set.

According to its commit message this is necessary because: "BayTrail-T
class of hardware requires EFI in order to powerdown and reboot and no
other reliable method exists".

But I have a Bay Trail CR tablet where the EFI_RESET_SHUTDOWN call does
not work, it simply returns without doing anything (AFAICT).

So it seems that some Bay Trail devices must use EFI for power-off, while
for others only ACPI works.

Note that efi_power_off() only gets used if the platform code defines
efi_poweroff_required() and that returns true, this currently only ever
happens on x86.

Since on the devices which need ACPI for power-off the EFI_RESET_SHUTDOWN
call simply returns, this patch makes the efi-reboot code remember the
old pm_power_off handler and if EFI_RESET_SHUTDOWN returns it falls back
to calling that.

This seems preferable to dmi-quirking our way out of this, since there
are likely quite a few devices suffering from this.

Subject: drivers/fbdev/efifb: Allow BAR to be moved instead of claiming it

On UEFI systems, the firmware may expose a Graphics Output Protocol (GOP)
instance to which the efifb driver attempts to attach in order to provide
a minimal, unaccelerated framebuffer. The GOP protocol itself is not very
sophisticated, and only describes the offset and size of the framebuffer
in memory, and the pixel format.

If the GOP framebuffer is provided by a PCI device, it will have been
configured and enabled by the UEFI firmware, and the GOP protocol will
simply point into a live BAR region. However, the GOP protocol itself does
not describe this relation, and so we have to take care not to reconfigure
the BAR without taking efifb's dependency on it into account.

Commit:

  55d728a40d36 ("efi/fb: Avoid reconfiguration of BAR that covers the framebuffer")

attempted to do so by claiming the BAR resource early on, which prevents the
PCI resource allocation routines from changing it.  However, it turns out
that this only works if the PCI device is not behind any bridges, since
the bridge resources need to be claimed first.

So instead, allow the BAR to be moved, but make the efifb driver deal
with that gracefully. So record the resource that covers the BAR early
on, and if it turns out to have moved by the time we probe the efifb
driver, update the framebuffer address accordingly.

While this is less likely to occur on x86, given that the firmware's
PCI resource allocation is more likely to be preserved, this is a
worthwhile sanity check to have in place, and so let's remove the
preprocessor conditional that makes it !X86 only.

Subject: mfd: rk808: Add RK805 support

The RK805 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:

    - Regulators
    - RTC
    - Clocking

Both RK808 and RK805 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

Subject: pinctrl: Add pinctrl driver for the RK805 PMIC

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.

This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.

Subject: pwm: mediatek: Fix clock control issue

In order to save some power, do not prepare the top and main clocks
during mtk_pwm_probe(). Instead, prepare the clocks only when necessary
and also make sure to enable the clocks to match the semantics of the
common clock framework.

While at it, don't explicitly disable all PWM channels in ->remove()
because all users should have done that already.

Subject: pwm: mediatek: Disable clock on PWM configuration failure

Make sure to disable the PWM clock if the PWM cannot be configured due
to the clock divider exceeding the maximum value.

While at it, replace the hardcoded maximum clock divider with a defined
constant to improve code readability.

Subject: pwm: samsung: Remove redundant checks from pwm_samsung_config()

If the requested period_ns and duty_ns values are identical to the last
programmed ones pwm_samsung_config() returns early and skips the
hardware configuration. The same checks are now done by the PWM core so
the driver specific ones can be removed.

Subject: pwm: pwm-samsung: fix suspend/resume support

Fix suspend/resume support:

- add disabled_mask to struct samsung_pwm_chip to track PWM
  disabled state information in pwm_samsung_{disable,enable}()

- rename pwm_samsung_config() to __pwm_samsung_config() and
  add extra force_period parameter to be used during resume
  (to force tin_ns and tcnt recalculation)

- add pwm_samsung_config() wrapper for preserving old behavior

- properly restore PWM configuration in pwm_samsung_resume()

- remove no longer needed pwm_samsung_suspend()

- update Copyrights

Subject: drm/i915/bxt: use NULL for GPIO connection ID

The commit 213e08ad60ba
	("drm/i915/bxt: add bxt dsi gpio element support")
enables GPIO support for Broxton based platforms.

While using that API we might get into troubles in the future, because
we can't rely on label name in the driver since vendor firmware might
provide any GPIO pin there, e.g. "reset", and even mark it in _DSD (in
which case the request will fail).

To avoid inconsistency and potential issues we have two options:
a) generate GPIO ACPI mapping table and supply it via
   acpi_dev_add_driver_gpios(), or
b) just pass NULL as connection ID.

The b) approach is much simpler and would work since the driver relies
on GPIO indices only. Moreover, the _CRS fallback mechanism, when
requesting GPIO, has been made stricter, and supplying non-NULL
connection ID when neither _DSD, nor GPIO ACPI mapping is present, is
making request fail.

Subject: drm/i915: Clear lost context-switch interrupts across reset

During a global reset, we disable the irq. As we disable the irq, the
hardware may be raising a GT interrupt that we then ignore, leaving it
pending in the GTIIR. After the reset, we then re-enable the irq,
triggering the pending interrupt. However, that interrupt was for the
stale state from before the reset, and the contents of the CSB buffer
are now invalid.

v2: Add a comment to make it clear that the double clear is purely my
paranoia.

Subject: rtc: ds1307: fix regmap config

Current max_register setting breaks reading nvram on certain chips and
also reading the standard registers on RX8130 where register map starts
at 0x10.

Subject: mmc: block: prevent propagating R1_OUT_OF_RANGE for open-ending mode

We to some extent should tolerate R1_OUT_OF_RANGE for open-ending
mode as it is expected behaviour and most of the backup partition
tables should be located near some of the last blocks which will
always make open-ending read exceed the capacity of cards.

Fixes: 9820a5b11101 ("mmc: core: for data errors, take response of stop cmd into account")
Fixes: a04e6bae9e6f ("mmc: core: check also R1 response for stop commands")

Subject: video: fbdev: pxa3xx_gcu: fix error return code in pxa3xx_gcu_probe()

platform_get_irq() returns an error code, but the pxa3xx_gcu driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Also, notice that platform_get_irq() no longer returns 0 on error:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

If dlfb_usb_probe drops to error path then there is only one
kref_init() call and no kref_get(), so second kref_put() leads to
use after free.

The patch removes superfluous kref_put on dlfb_usb_probe error path.

Subject: regulator: fan53555: fix I2C device ids

The device tree nodes all correctly describe the regulators as
syr827 or syr828, but the I2C device id is currently set to the
wildcard value of syr82x in the driver.  This causes udev to fail
to match the driver module with the modalias data from sysfs.

Fix this by replacing the I2C device ids with ones that match the
device tree descriptions, with syr827 and syr828.  Tested on
Firefly rk3288 board.  The syr82x id was not used anywhere.

i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

Subject: clk: rockchip: fix the rv1108 clk_mac sel register description

The source clock ordering is wrong, as shown in the TRM:
cru_sel24_con[8]
rmii_extclk_sel
clock source select control register
1'b0: from internal PLL
1'b1: from external IO

Subject: phy: sun4i-usb: Support secondary clock for HSIC PHY

On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires
two clocks instead of one.

On all Allwinner SoCs that share the common USB PHY design supported by
the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there
is at most one HSIC PHY, typically the last.

In this patch we take advantage of these known constraints and store an
index in the compatible-string-related config structure describing which
PHY is HSIC, needing the extra hsic_12M clock.

Subject: phy: sun4i-usb: Support A83T USB PHYs

The A83T has 3 USB PHYs, 1 for OTG, 1 for standard USB, 1 for USB HSIC.
The phy initialization procedure is very different from other SoCs, but
the PMU bits are the same, with additional bits for HSIC.

Subject: phy: rockchip-inno-usb2: add support for otg-mux interrupt

The otg-id/otg-bvalid/linestate interrupts are multiplexed together
in otg-port on some Rockchip SoC (e.g RV1108), this patch add support
for it.

Subject: phy: phy-twl4030-usb: silence an uninitialized variable warning

The "check" variable isn't necessarily initialized when we print it out
in the debugging messages.  It's a pretty haphazard affair and it
doesn't matter very much what we initialize "check" to.

Subject: crypto: sahara - constify platform_device_id

platform_device_id are not supposed to change at runtime. All functions
working with platform_device_id provided by <linux/platform_device.h>
work with const platform_device_id. So mark the non-const structs as
const.

Subject: crypto: cavium - add release_firmware to all return case

Two return case misses to call release_firmware() and so leak some
memory.

This patch create a fw_release label (and so a common error path)
and use it on all return case.

Subject: crypto: rockchip - Don't dequeue the request when device is busy

The device can only process one request at a time. So if multiple
requests came at the same time, we can enqueue them first, and
dequeue them one by one when the device is idle.

Subject: mfd: da9052: Make touchscreen registration optional

If the touchscreen pins are used as general purpose analogue
input, the touchscreen driver should not be used. The pins
will be handled by the existing hwmon driver instead.

Subject: hwmon: da9052: Add support for TSI channel

TSI channel has a 4 channel mux connected to it and is normally
used for touchscreen support. The hardware may alternatively
use it as general purpose adc.

Subject: drm/nouveau/disp/gf119-: avoid creating non-existent heads

We assume that each board has 4 heads for GF119+. However this is not
necessarily true - in the case of a GP108 board, the register indicated
that there were only 2.

Subject: drm/nouveau/bios: Demote missing fp table message to NV_DEBUG.

This warning seems to pop up mainly in laptop cards. Silence it as
it is expected behavior.

Subject: drm/nouveau/disp: Silence DCB warnings.

Most of these errors seem to be WFD related. Official documentation
says dcb type 8 is reserved. It's probably used for WFD. Silence
the warning in either case.

Connector type 70 is stated to be a virtual connector for WiFi
display. Since we know this, don't warn that we don't.

Subject: initial support (display-only) for GP108

Forked from GP107 implementation. Secboot/gr left out as we don't have
signed blobs from NVIDIA in linux-firmware.

(Ben): Was unable to mmiotrace the binary driver for unknown reasons,
       so not able to 100% confirm that no other changes from GP107
       are needed.  Quick testing shows it seems to work well enough
       for display.  Due to NVIDIA dragging their heels on getting
       signed firmware to us, this is the best we can do for now.

Pre-nv50 YUV overlays have stringent requirements for working with the
internal machinery. Instead of rejecting these at update_plane time, we
should instead prevent the framebuffers from being created in the first
place.

Subject: drm/nouveau/kms/nv04-nv40: improve overlay error detection, fix pitch
 setting

We were previously setting the pitch based on a perfectly packed buffer.
This does not necessarily happen. Either modetest started generating
such buffers recently, or earlier testing only happened with well-picked
overlay sizes.

While we're at it, beef up and refactor the error state detection.

Subject: drm/nouveau/kms/nv04-nv4x: fix exposed format list

drm_crtc_init exposes the XRGB8888 and ARGB8888 formats. In actuality,
ARGB8888's 32-bit depth messes up some formulas that weren't meant for
it, and the alpha is fairly meaningless for the primary plane.

The modesetting logic appears to be fully prepared for RGB565 as well as
XRGB1555 however, as tested with modetest.

Subject: drm/nouveau/pci/msi: disable MSI on big-endian platforms by default

It appears that MSI does not work on either G5 PPC nor on a E5500-based
platform, where other hardware is reported to work fine with MSI.

Both tests were conducted with NV4x hardware, so perhaps other (or even
this) hardware can be made to work. It's still possible to force-enable
with config=NvMSI=1 on load.

Subject: drm/nouveau/kms/nv50: perform null check on msto[i] rathern than msto

The null check on the array msto is incorrect since msto is never
null. The null check should be instead on msto[i] since this is
being dereferenced in the call to drm_mode_connector_attach_encoder.

Thanks to Emil Velikov for pointing out the mistake in my original
fix and for suggesting the correct fix.

Subject: rtc: puv3: make alarms useful

Currently, the driver unregisters the IRQs when the rtc character device is
closed. This means that the device needs to stay open to get alarms while
the usual use case will open the device, set the alarm and close the
device.

Move the IRQ requests to puv3_rtc_probe() and use the devm managed versions
so we don't need to free them.

Subject: pinctrl: amd: fix error return code in amd_gpio_probe()

platform_get_irq() returns an error code, but the pinctrl-amd driver
ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

Subject: pinctrl: intel: Disable GPIO pin interrupts in suspend

The fix prevents unintended wakes from second level GPIO pin interrupts.

On some Intel Kabylake platforms, it is observed that GPIO pin interrupts
can wake the platform from suspend-to-idle, even though the IRQ is not
configured as IRQF_NO_SUSPEND or enable_irq_wake().

This can cause undesired wakes on Mobile devices such as Laptops and
Chromebook devices. For example a headset jack insertion is not a desired
wake source on Chromebook devices.

The pinctrl-intel (GPIO controller) driver implements a "Shared IRQ" model.
All GPIO pin interrupts are OR'ed and mapped to a first level IRQ14 (or
IRQ15). The driver registers an irq_chip struct and maps an irq_domain for
the GPIO pin interrupts. The IRQ14 handler demuxes and calls the second
level IRQ for the respective pin.

In the suspend entry flow, at suspend_noirq stage, the kernel disables IRQs
that are not marked for wake. The pinctrl-intel driver does not implement a
irq_disable()  callback (to take advantage of lazy disabling). The
pinctrl-intel GPIO interrupts are not disabled in hardware during suspend
entry, and thus are able to wake the SoC out of suspend-to-idle.

This patch sets the IRQCHIP_MASK_ON_SUSPEND flag for the GPIO irq_chip, to
disable the second level interrupts at suspend_noirq stage via the irq_mask
callbacks. The irq_mask callback disables the IRQs in hardware by
programming the corresponding GPIO pad registers. Only IRQs that are not
marked for wake are disabled.

Subject: pinctrl: sunxi: fix wrong irq_banks number for H5 pinctrl

The pin controller of Allwinner H5 has three IRQ banks, however in old
versions of drivers and device trees, only two are set, which makes
PG bank IRQ not available.

If it's directly set to 3, the old device trees will fail to boot.

Add a workaround (and a warning) for older device trees, and allow new
device trees to use correct 3 IRQ banks.

Fixes: 838adb576d4a ("drivers: pinctrl: add driver for Allwinner H5 SoC")

Subject: drm: Release driver tracking before making the object available again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is the same bug as we fixed in commit f6cd7daecff5 ("drm: Release
driver references to handle before making it available again"), but now
the exposure is via the PRIME lookup tables. If we remove the
object/handle from the PRIME lut, then a new request for the same
object/fd will generate a new handle, thus for a short window that
object is known to userspace by two different handles. Fix this by
releasing the driver tracking before PRIME.

Fixes: 0ff926c7d4f0 ("drm/prime: add exported buffers to current fprivs
imported buffer list (v2)")

Subject: pinctrl: intel: Add Intel Lewisburg GPIO support

Intel Lewisburg has the same GPIO hardware than Intel Sunrisepoint-H
except few differences in register offsets and pin lists. Because of
this we add a separate pinctrl driver for Lewisburg.

Subject: mfd: db8500-prcmu: Get rid of cpufreq dependency

The ARMSS clock, also known as the operating point of the
CPU, should not cross-depend on cpufreq like this. Move
the code to use just frequencies and remove the false
frequency (1GHz) and put in the actual frequency provided
by the ARMSS clock (998400000 Hz) as part of the process.

After this and the related cpufreq patch, the DB8500 will
simply use the standard DT cpufreq driver to change the
operating points through the common clock framework using
the ARMSS clock.

Subject: cpufreq: dbx500: Delete obsolete driver

We have moved the Ux500 over to use the generic DT based
cpufreq driver, so delete the old custom driver.

At the same time select CPUFREQ_DT from the machine's
Kconfig in order to satisfy the "default ARCH_U8500"
selection on the old driver.

Subject: cpufreq: Cap the default transition delay value to 10 ms

If transition_delay_us isn't defined by the cpufreq driver, the default
value of transition delay (time after which the cpufreq governor will
try updating the frequency again) is currently calculated by multiplying
transition_latency (nsec) with LATENCY_MULTIPLIER (1000) and then
converting this time to usec. That gives the exact same value as
transition_latency, just that the time unit is usec instead of nsec.

With acpi-cpufreq for example, transition_latency is set to around 10
usec and we get transition delay as 10 ms. Which seems to be a
reasonable amount of time to reevaluate the frequency again.

But for platforms where frequency switching isn't that fast (like ARM),
the transition_latency varies from 500 usec to 3 ms, and the transition
delay becomes 500 ms to 3 seconds. Of course, that is a pretty bad
default value to start with.

We can try to come across a better formula (instead of multiplying with
LATENCY_MULTIPLIER) to solve this problem, but will that be worth it ?

This patch tries a simple approach and caps the maximum value of default
transition delay to 10 ms. Of course, userspace can still come in and
change this value anytime or individual drivers can rather provide
transition_delay_us instead.

Subject: iommu/mediatek: Move MTK_M4U_TO_LARB/PORT into mtk_iommu.c

The definition of MTK_M4U_TO_LARB and MTK_M4U_TO_PORT are shared by
all the gen2 M4U HWs. Thus, Move them out from mt8173-larb-port.h,
and put them into the c file.

Subject: iommu/mediatek: Add mt2712 IOMMU support

The M4U IP blocks in mt2712 is MTK's generation2 M4U which use the
ARM Short-descriptor like mt8173, and most of the HW registers are
the same.

The difference is that there are 2 M4U HWs in mt2712 while there's
only one in mt8173. The purpose of 2 M4U HWs is for balance the
bandwidth.

Normally if there are 2 M4U HWs, there should be 2 iommu domains,
each M4U has a iommu domain.

Subject: iommu/mediatek: Merge 2 M4U HWs into one iommu domain

In theory, If there are 2 M4U HWs, there should be 2 IOMMU domains.
But one IOMMU domain(4GB iova range) is enough for us currently,
It's unnecessary to maintain 2 pagetables.

Besides, This patch can simplify our consumer code largely. They don't
need map a iova range from one domain into another, They can share the
iova address easily.

Subject: iommu/mediatek: Move pgtable allocation into domain_alloc

After adding the global list for M4U HW, We get a chance to
move the pagetable allocation into the mtk_iommu_domain_alloc.
Let the domain_alloc do the right thing.

This patch is for fixing this problem[1].

Subject: iommu/mediatek: Enlarge the validate PA range for 4GB mode

This patch is for 4GB mode, mainly for 4 issues:
1) Fix a 4GB bug:
   if the dram base is 0x4000_0000, the dram size is 0xc000_0000.
   then the code just meet a corner case because max_pfn is
   0x10_0000.
   data->enable_4GB = !!(max_pfn > (0xffffffffUL >> PAGE_SHIFT));
   It's true at the case above. That is unexpected.
2) In mt2712, there is a new register for the 4GB PA range(0x118)
   we should enlarge the max PA range, or the HW will report
   error.
   The dram range is from 0x1_0000_0000 to 0x1_ffff_ffff in the 4GB
   mode, we cut out the bit[32:30] of the SA(Start address) and
   EA(End address) into this REG_MMU_VLD_PA_RNG(0x118).
3) In mt2712, the register(0x13c) is extended for 4GB mode.
   bit[7:6] indicate the valid PA[32:33]. Thus, we don't mask the
   value and print it directly for debug.
4) if 4GB is enabled, the dram PA range is from 0x1_0000_0000 to
   0x1_ffff_ffff. Thus, the PA from iova_to_pa should also '|' BIT(32)

Subject: memory: mtk-smi: Degrade SMI init to module_init

The initialization of MediaTek power manager(SCPSYS) is
builtin_platform_driver, and SMI must depend on power-domain.
Thus, currently subsys_initcall for SMI is unnecessary, SMI will be
always probe defered by power-domain. Degrade it to module_init.

In addition, there are two small changes about the probe sequence:
1) Delete this two lines.
    	if (!dev->pm_domain)
		return -EPROBE_DEFER;
   This is not helpful. the platform driver framework guarantee this.
   The "dev_pm_domain_attach" in the "platform_drv_probe" will return
   EPROBE_DEFER if its powerdomain is not ready.

2) Add the probe-defer for the smi-larb device should waiting for
   smi-common.
   In mt2712, there are 2 smi-commons, 10 smi-larbs. All will be
   probe-defered by the power-domain, there is seldom case that
   smi-larb probe done before smi-common. then it will hang like
   this:

Subject: drm/msm: Attach the GPU MMU when it is created

Currently the GPU MMU is attached in the adreno_gpu code but as
more and more of the GPU initialization moves to the generic
GPU path we have a need to map and use GPU memory earlier and
earlier.  There isn't any reason to defer attaching the MMU
until later so attach it right after the address space is
created so it can be used immediately.

Subject: drm/msm: Add a helper function for in-kernel buffer allocations

Nearly all of the buffer allocations for kernel allocate an buffer object,
virtual address and GPU iova at the same time. Make a helper function to
handle the details.

Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org>
[dropped msm_fbdev conversion to new helper, since it interferes with
display-handover work, where we want to separate allocation and mapping]

Subject: drm/msm/mdp5: add tracking for clk enable-count

Accessing registers for an unclocked block is an insta-reboot on
snapdragon devices.  So add a bit of logic to track the enable_count so
we can WARN_ON() unclocked register writes.  This makes it much easier
to track down mistakes.

The drm_framebuffer is refcnt'd these days and will unref the underlying
bo as needed.  So we can simplify a little.

Subject: drm/msm/mdp5: mark runtime_pm functions as __maybe_unused

When CONFIG_PM is disabled, we get harmless warnings about unused
functions:

drivers/gpu/drm/msm/mdp/mdp5/mdp5_kms.c:1025:12: error: 'mdp5_runtime_resume' defined but not used [-Werror=unused-function]

 static int mdp5_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~

This marks both functions as __maybe_unused so the compiler
can drop them silently.

+Linux Kernel Driver for Huawei Intelligent NIC(HiNIC) family
+============================================================
+
+Overview:
+=========
+HiNIC is a network interface card for the Data Center Area.
+
+The driver supports a range of link-speed devices (10GbE, 25GbE, 40GbE, etc.).
+The driver supports also a negotiated and extendable feature set.
+
+Some HiNIC devices support SR-IOV. This driver is used for Physical Function
+(PF).
+
+HiNIC devices support MSI-X interrupt vector for each Tx/Rx queue and
+adaptive interrupt moderation.
+
+HiNIC devices support also various offload features such as checksum offload,
+TCP Transmit Segmentation Offload(TSO), Receive-Side Scaling(RSS) and
+LRO(Large Receive Offload).
+
+
+Supported PCI vendor ID/device IDs:
+===================================
+
+19e5:1822 - HiNIC PF
+
+
+Driver Architecture and Source Code:
+====================================
+
+hinic_dev - Implement a Logical Network device that is independent from
+specific HW details about HW data structure formats.
+
+hinic_hwdev - Implement the HW details of the device and include the components
+for accessing the PCI NIC.
+
+hinic_hwdev contains the following components:
+===============================================
+
+HW Interface:
+=============
+
+The interface for accessing the pci device (DMA memory and PCI BARs).
+(hinic_hw_if.c, hinic_hw_if.h)
+
+Configuration Status Registers Area that describes the HW Registers on the
+configuration and status BAR0. (hinic_hw_csr.h)
+
+MGMT components:
+================
+
+Asynchronous Event Queues(AEQs) - The event queues for receiving messages from
+the MGMT modules on the cards. (hinic_hw_eqs.c, hinic_hw_eqs.h)
+
+Application Programmable Interface commands(API CMD) - Interface for sending
+MGMT commands to the card. (hinic_hw_api_cmd.c, hinic_hw_api_cmd.h)
+
+Management (MGMT) - the PF to MGMT channel that uses API CMD for sending MGMT
+commands to the card and receives notifications from the MGMT modules on the
+card by AEQs. Also set the addresses of the IO CMDQs in HW.
+(hinic_hw_mgmt.c, hinic_hw_mgmt.h)
+
+IO components:
+==============
+
+Completion Event Queues(CEQs) - The completion Event Queues that describe IO
+tasks that are finished. (hinic_hw_eqs.c, hinic_hw_eqs.h)
+
+Work Queues(WQ) - Contain the memory and operations for use by CMD queues and

Subject: RDMA/uverbs: Initialize cq_context appropriately

Initializing cq_context with ev_queue in create_cq(), leads to NULL pointer
dereference in ib_uverbs_comp_handler(), if application doesnot use completion
channel. This patch fixes the cq_context initialization.

From e093111ddb6c786e32b882108c1c08ef83d781f4 Mon Sep 17 00:00:00 2001
From: "Amrani, Ram" <Ram.Amrani@cavium.com>
Date: Tue, 27 Jun 2017 17:04:42 +0300
Subject: IB/core: Fix input len in multiple user verbs

Most user verbs pass user data to the kernel with the inclusion of the
ib_uverbs_cmd_hdr structure. This is problematic because the vendor has
no ideas if the verb was called by a legacy verb or an extended verb.
Also, the incosistency between the verbs is confusing.

Fixes: 565197dd8fb1 ("IB/core: Extend ib_uverbs_create_cq")

Subject: liquidio: move macro definition to a proper place

The macro LIO_CMD_WAIT_TM is not specific to the PF driver; it can be used
by the VF driver too, so move its definition from a PF-specific header file
to one that's common to PF and VF.

Subject: IB/hfi1: Remove lstate from hfi1_pportdata

Do not track logical state separately from host_link_state. Deduce
logical state from host_link_state when required. Transitions in
set_link_state and goto_offline already make sure host_link_state
reflects hardware's logical state properly.

Subject: IB/hfi1: Use host_link_state to read state when DC is shut down

When DC is shut down (by e.g.  disconnecting the cable), the
driver should use host_link_state to get port's current
physical state. This is due to the fact that physical state
is read from DC's CSRs and when DC is shut down and state is
changed, its registers are not impacted.

Subject: IB/hfi1: Protect context array set/clear with spinlock

The rcd array can be accessed from user context or during interrupts.
Protecting this with a mutex isn't a good idea because the mutex should
not be used from an IRQ.

Protect the allocation and freeing of rcd array elements with a
spinlock.

Subject: IB/hf1: User context locking is inconsistent

There is a mixture of mutex and spinlocks to protect receive context
(rcd/uctxt) information.  This is not used consistently.

Use the mutex to protect device receive context information only.
Use the spinlock to protect sub context information only.

Protect access to items in the rcd array with a spinlock and
reference count.

Remove spinlock around dd->rcd array cleanup.  Since interrupts are
disabled and cleaned up before this point, this lock is not useful.

From 13c19222889daf91da36b7fb63b5d5d9ce89b377 Mon Sep 17 00:00:00 2001
From: Don Hiatt <don.hiatt@intel.com>
Date: Fri, 4 Aug 2017 13:53:51 -0700
Subject: IB/rdmavt, hfi1, qib: Modify check_ah() to account for extended LIDs

rvt_check_ah() delegates lid verification to underlying
driver. Underlying driver uses different conditions to
check for dlid depending on whether the device supports
extended LIDs

Subject: IB/hfi1: Add support to receive 16B bypass packets

We introduce a struct hfi1_16b_header to support 16B headers.
16B bypass packets are received by the driver and processed
similar to 9B packets. Add basic support to handle 16B packets.

Subject: IB/hfi1: Determine 9B/16B L2 header type based on Address handle

When address handle attributes are initialized, the LIDs are
transformed to be in the 32 bit LID space.
When constructing the header, hfi1 driver will look at the LID
to determine the packet header to be created.

Subject: IB/hfi1: Enhance PIO/SDMA send for 16B

PIO/SDMA send logic now uses the hdr_type field to determine
the type of packet that has been constructed. Based on the hdr_type,
certain things such as PBC flags, padding count and the LT extra
trailing bytes are determined.

Subject: IB/hfi1: Load fallback platform configuration per HFI device

Currently fallback configuration is loaded once per driver instance.
With multiple HFI devices in the same system the current code may not
load the platform config data for the device. Change fallback platform
config data loading to be per device.

Do not track physical state separately from host_link_state.
Deduce physical state from host_link_state when required.
Change cache_physical_state to log_physical_state to make
sure host_link_state reflects hardwares physical state properly.

Subject: IB/hfi1: Remove HFI1_VERBS_31BIT_PSN option

Remove HFI1_VERBS_31BIT_PSN Kconfig option leaving only 31-bit PSNs
available. The option was implemented in the early days of the driver
and is no longer needed.

Date: Tue, 8 Aug 2017 20:38:45 -0500
Subject: i40iw: Improve CQP timeout logic

The current timeout logic for Control Queue-Pair (CQP) OPs
does not take into account whether CQP makes progress but
rather blindly waits for a large timeout value, 100000 jiffies
for the completion event. Improve this by setting the timeout
based on whether the CQP is making progress or not. If the CQP
is hung, the timeout will happen sooner, in 5000 jiffies. Each
time the CQP progress is detetcted, the timeout extends by 5000
jiffies.

 dra7xx_pcie_probe()

platform_get_irq() returns an error code, but the pci-dra7xx driver ignores
it and always returns -EINVAL. This is not correct and prevents
-EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq() on failure.

This issue was detected with the help of Coccinelle.

Subject: ACPICA: Fix acpi_evaluate_object_typed()

Commit 2d2a954375a0 (ACPICA: Update two error messages to emit
control method name) causes acpi_evaluate_object_typed() to fail
if its pathname argument is NULL, but some callers of that function
in the kernel, particularly acpi_nondev_subnode_data_ok(), pass
NULL as pathname to it and expect it to work.

For this reason, make acpi_evaluate_object_typed() check if its
pathname argument is NULL and fall back to using the pathname of
its handle argument if that is the case.

Subject: IB/mlx5: use kvmalloc_array for mlx5_ib_wq

We observed multiple times on our Lustre OSS servers that when
the system memory is fragmented, kmalloc() in create_kernel_qp()
could fail order 4/5 allocations while we still have many free pages.

Switch to kvmalloc_array() to allow the operation to contine.

Subject: PCI: dwc: Clear MSI interrupt status after it is handled, not before

If the interrupt status is cleared before it is handled, it is possible
that another interrupt will trigger while servicing the previous one.  This
is causing timeouts in some wireless lan cards which use PCIe.

Clear MSI interrupt status after it gets serviced instead of before calling
generic_handler.

Subject: ACPI: device property: Fix node lookup in
 acpi_graph_get_child_prop_value()

acpi_graph_get_child_prop_value() is intended to find a child node with a
certain property value pair. The check

	if (!fwnode_property_read_u32(fwnode, prop_name, &nr))
		continue;

is faulty: fwnode_property_read_u32() returns zero on success, not on
failure, leading to comparing values only if the searched property was not
found.

Moreover, the check is made against the parent device node instead of
the child one as it should be.

Fixes: 79389a83bc38 (ACPI / property: Add support for remote endpoints)

Subject: rdma: Autoload netlink client modules

If a message comes in and we do not have the client in the table, then
try to load the module supplying that client using MODULE_ALIAS to find
it.

This duplicates the scheme seen in other netlink muxes (eg nfnetlink).

Subject: hv_netvsc: Add ethtool handler to set and get UDP hash levels

The patch add the functions to switch UDP hash level between
L3 and L4 by ethtool command. UDP over IPv4 and v6 can be set
differently. The default hash level is L4. We currently only
allow switching TX hash level from within the guests.

On Azure, fragmented UDP packets have high loss rate with L4
hashing. Using L3 hashing is recommended in this case.

For example, for UDP over IPv4 on eth0:
To include UDP port numbers in hasing:
	ethtool -N eth0 rx-flow-hash udp4 sdfn
To exclude UDP port numbers in hasing:
	ethtool -N eth0 rx-flow-hash udp4 sd
To show UDP hash level:
	ethtool -n eth0 rx-flow-hash udp4

Subject: net: mvpp2: fix the synchronization module bypass macro name

The macro defining the bit to toggle to bypass or not the
synchronization module is wrongly named. Writing 1 will disable bypass.
This patch s/MVPP22_CTRL4_SYNC_BYPASS/MVPP22_CTRL4_SYNC_BYPASS_DIS/.

This moves the mii configuration in the ndo_open path, to allow handling
different mii configurations later and to switch between these
configurations at runtime.

Subject: net: mvpp2: set maximum packet size for 10G ports

Set maximum packet size for XLG 10G ports. Missing maximum packet size
for XLG configuration will cause kernel panic if oversized packet is
received by port.

The patch adds GoP (group of ports) initialization functions. The mvpp2
driver was relying on the firmware/bootloader initialization; this patch
moves this setup to the mvpp2 driver.

Subject: net: phy: Deal with unbound PHY driver in phy_attached_print()

Priit reported that stmmac was crashing with the trace below. This is because
phy_attached_print() is called too early right after the PHY device has been
found, but before it has a driver attached, since that is only done in
phy_probe() which occurs later.

Fix this by dealing with a possibly NULL phydev->drv point since that can
happen here, but could also happen if we voluntarily did an unbind of the
PHY device with the PHY driver.

Subject: staging: unisys: Switch to use new generic UUID API

There are new types and helpers that are supposed to be used in new code.

As a preparation to get rid of legacy types and API functions do
the conversion here.

While here, re-indent couple of lines to increase readability.

Subject: staging: unisys: visorbus: Update comment style vbuschannel.h

Moved blocked comment on to own line at beginning of struct to follow
standard. Since this is an internal structure, the block comment isn't
actually a kernel-doc so we only start the block with one asterisk.

Subject: staging: unisys: include: fix improper use of dma_data_direction

Replace use of standard Linux dma_data_direction with a Unisys-
specific uis_dma_data_direction and provide a function to convert
from the latter to the former.  This is necessary because Unisys
s-Par depends on the exact format of this field in multiple OSs
and languages, and so using the standard version creates an
unnecessary dependency between the kernel and s-Par.

Subject: staging: unisys: visorbus: fix include dependency

Due to include order, the visorbus_private.h file was missing a required
include header visorbus.h. If visorchipset.c or visorbus_main.c ever were
to change the order of the includes for visobus.h and visorbus_private.h,
the code would fail to compile.

Subject: fsl/man: Inherit parent device and of_node

Junote Cai reported that he was not able to get a DSA setup involving the
Freescale DPAA/FMAN driver to work and narrowed it down to
of_find_net_device_by_node(). This function requires the network device's
device reference to be correctly set which is the case here, though we have
lost any device_node association there.

The problem is that dpaa_eth_add_device() allocates a "dpaa-ethernet" platform
device, and later on dpaa_eth_probe() is called but SET_NETDEV_DEV() won't be
propagating &pdev->dev.of_node properly. Fix this by inherenting both the parent
device and the of_node when dpaa_eth_add_device() creates the platform device.

Subject: staging: lustre: uapi: Move functions out of lustre_idl.h

Migrate functions set/get_mrc_cr_flags, ldlm_res_eq
ldlm_extent_overlap, ldlm_extent_contain,
ldlm_request_bufsize, and all the PTLRPC dump_*
functions out of lustre_idl.h which is a UAPI header
to the places in the kernel code they are actually used.
Delete unused lmv_mds_md_stripe_count and
agent_req_in_final_state.

Subject: staging: lustre: uapi: return error code for ostid_set_id

Currently the function ostid_set_id() just logs an error
and just keeps going. This function is also used by user
land tools so having special lustre kernel debugging
code is not desired. So instead just return an error
code and have the calling kernel code print the error
instead.

Subject: staging: lustre: uapi: move lu_fid, ost_id funcs out of lustre_idl.h

Move lu_fid functions into lustre/lustre_fid.h
Move ost_id functions into lustre/lustre_ostid.h
Fix indenting, include new headers as needed.

Several inline functions in the header lustre_ostid.h
are using debug macros instead of returning proper errors.
Remove the debug macros and properly handle the returned
error codes. Place both UAPI headers lustre_fid.h and
lustre_ostid.h into the uapi directory.

Subject: staging: lustre: uapi: remove unused function in lustre_disk.h

Delete code that is used by only the server or just in user
land. Now this file is a normal kernel header. The UAPI
version of this header is only needed for server side so
no need to create a new header in uapi directory.

Subject: staging: lustre: uapi: remove userland version of obd_ioctl_*()

The header lustre_ioctl.h has both kernel and user space versions
of obd_ioctl_*() functions. Lets remove the user land version
which have been integrated into the lustre tools.

Subject: staging: lustre: uapi: move obd_ioctl_is_invalid() to linux-module.c

The inline function obd_ioctl_is_invalid() is no longer needed by
userland and also the function was pretty bug for a inline function.
Since this is the case we can move this kernel only code to the
linux-module.c which is the only place it is used.

From 30bfc47885a486ee5ce5fc6adefac9b06ed704d7 Mon Sep 17 00:00:00 2001
From: James Simmons <jsimmons@infradead.org>
Date: Sat, 19 Aug 2017 22:26:07 -0400
Subject: staging: lustre: uapi: use __ALIGN_KERNEL for lustre_ioctl.h

Replace cfs_size_round() standard __ALIGN_KERNEL macro. This
removes the dependency of libcfs.h which is a kernel only
header.

Subject: staging: lustre: uapi: don't memory allocate in UAPI header

The inline function lustre_cfg_new() calls kzalloc() but
this is a UAPI header. Remove kzalloc() and rename the
function to lustre_cfg_init(). The lustre kernel code
that was calling lustre_cfg_new() can doing the memory
allocation and pass the new buffer to lustre_cfg_init()
to fill in.

Subject: staging: lustre: uapi: move lustre_cfg_string() to obd_config.c

To perserve the truncate warning move lustre_cfg_string()
to obd_config.c. A identical function was created for
userland. This function was a bit big for a inline function.

In class_config_llog_handler() a flag, inst, was used to
determine if it was safe to call kfree. Its not needed so
remove the flag.

From 955073c4fe4bd87a074d80c1e4098ffd1c49356a Mon Sep 17 00:00:00 2001
From: James Simmons <jsimmons@infradead.org>
Date: Sat, 19 Aug 2017 22:26:20 -0400
Subject: staging: lustre: uapi: remove need for libcfs.h from lustre_cfg.h

Several libcfs.h macros are present in lustre_cfg.h, but libcfs.h
is not available so lets replace those macros with real code.
The header libcfs.h also provides errno.h so with libcfs.h gone
include errno.h directly.

Subject: staging: lustre: uapi: remove libcfs.h from lustre_id.h/lustre_user.h

These are the last UAPI headers that contain libcfs.h which is
internal kernel header. Since it is not available to user land
remove libcfs.h and add the need headers that libcfs.h provided.

- * Lustre wire protocol definitions.
- *
- * ALL structs passing over the wire should be declared here.  Structs
- * that are used in interfaces with userspace should go in lustre_user.h.
- *
- * All structs being declared here should be built from simple fixed-size
- * types (__u8, __u16, __u32, __u64) or be built from other types or
- * structs also declared in this file.  Similarly, all flags and magic
- * values in those structs should also be declared here.  This ensures
- * that the Lustre wire protocol is not influenced by external dependencies.
- *
- * The only other acceptable items in this file are VERY SIMPLE accessor
- * functions to avoid callers grubbing inside the structures. Nothing that
- * depends on external functions or definitions should be in here.
- *
- * Structs must be properly aligned to put 64-bit values on an 8-byte
- * boundary.  Any structs being added here must also be added to
- * utils/wirecheck.c and "make newwiretest" run to regenerate the
- * utils/wiretest.c sources.  This allows us to verify that wire structs
- * have the proper alignment/size on all architectures.
- *
- * DO NOT CHANGE any of the structs, flags, values declared here and used
- * in released Lustre versions.  Some structs may have padding fields that
- * can be used.  Some structs might allow addition at the end (verify this
- * in the code to ensure that new/old clients that see this larger struct
- * do not fail, otherwise you need to implement protocol compatibility).

Subject: staging: lustre: uapi: remove CONFIG_LUSTRE_OBD_MAX_IOCTL

Now that lustre_ioctl.h is a UAPI header the kernel configuration
option CONFIG_LUSTRE_OBD_MAX_IOCTL needs to be remove. The user
land utilites will no longer be able to see this option and
actually they never used this option before. Since this is the
case setting the kernel configuration to something other than
8K could actually break things. The best option is just hard
code it to 8K.

Commit c4ea41ba195d ("binder: use group leader instead of open thread")'
was incomplete and didn't update a check in binder_mmap(), causing all
mmap() calls into the binder driver to fail.

On binder_init() the devices string is duplicated and smashed into individual
device names which are passed along. However, the original duplicated string
wasn't freed in case binder_init() failed. Let's free it on error.

commit 26549d177410 ("binder: guarantee txn complete / errors delivered

Subject: irqchip: Add UniPhier AIDET irqchip driver

UniPhier SoCs contain AIDET (ARM Interrupt Detector).  This is intended
to provide additional features that are not covered by GIC.  The main
purpose is to provide logic inverter to support low level and falling
edge trigger types for interrupt lines from on-board devices.

+UniPhier AIDET
+
+UniPhier AIDET (ARM Interrupt Detector) is an add-on block for ARM GIC (Generic
+Interrupt Controller).  GIC itself can handle only high level and rising edge
+interrupts.  The AIDET provides logic inverter to support low level and falling
+edge interrupts.
+
+Required properties:
+- compatible: Should be one of the following:
+    "socionext,uniphier-ld4-aidet"  - for LD4 SoC
+    "socionext,uniphier-pro4-aidet" - for Pro4 SoC
+    "socionext,uniphier-sld8-aidet" - for sLD8 SoC
+    "socionext,uniphier-pro5-aidet" - for Pro5 SoC
+    "socionext,uniphier-pxs2-aidet" - for PXs2/LD6b SoC
+    "socionext,uniphier-ld11-aidet" - for LD11 SoC
+    "socionext,uniphier-ld20-aidet" - for LD20 SoC
+    "socionext,uniphier-pxs3-aidet" - for PXs3 SoC
+- reg: Specifies offset and length of the register set for the device.
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an interrupt
+  source.  The value should be 2.  The first cell defines the interrupt number
+  (corresponds to the SPI interrupt number of GIC).  The second cell specifies
+  the trigger type as defined in interrupts.txt in this directory.
+
+Example:
+
+	aidet: aidet@5fc20000 {
+		compatible = "socionext,uniphier-pro4-aidet";
+		reg = <0x5fc20000 0x200>;
+		interrupt-controller;
+		#interrupt-cells = <2>;
+	};

Subject: irqchip: Convert to using %pOF instead of full_name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

From beea6214d1cc5bb08ce25ffe06b57fb948445bed Mon Sep 17 00:00:00 2001
From: Tomi Valkeinen <tomi.valkeinen@ti.com>
Date: Tue, 13 Jun 2017 12:02:09 +0300
Subject: drm/omap: fix analog tv-out modecheck

omapdrm rejects all venc (analog tv-out) videomodes, due to somewhat
strict checking of the values, making tv-out unusable.

We only support two videomodes, one for PAL and one for NTSC, so instead
of trying to check every field in the videomode struct, this patch makes
the driver check only the pixel clock and the size of the display.

Subject: drm/omap: fix i886 work-around

7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for
errata i886") changed how the PLL dividers and multipliers are
calculated. While the new way should work fine for all the PLLs, it
breaks omap5 PLLs. The issues seen are rather odd: seemed that the
output clock rate is half of what we asked. It is unclear what's causing
there issues.

As a work-around this patch adds a "errata_i886" flag, which is set only
for DRA7's PLLs, and the PLL setup is done according to that flag.

Subject: drm/omap: work-around for omap3 display enable

Seems that on omap3 enabling a crtc without any planes causes a sync
lost flood. This only happens on the first enable, and after that it
works. This looks like an HW issue and it's unclear why this is
happening or how to fix it.

This started happening after 897145d0c7010b4e07fa9bc674b1dfb9a2c6fff9
("drm/omapdrm: Move commit_modeset_enables() before commit_planes()")
which, as a work-around, changed omapdrm first to do the modeset enable,
and plane set only after that. This WA should be fine on all DSS
versions, but apparently OMAP3 DSS is an exception.

This patch reverts that work-around for OMAP3 DSS.

Subject: soc/tegra: Restrict SoC device registration to Tegra

Commit 8a46828e623c ("soc/tegra: Register SoC device") added an initcall
to register the SoC device on Tegra. However, that code is unrestricted
and will run on all platforms, causing unwanted warnings.

Fix this by first checking that we're running on hardware that supports
the fuses block that we use to provide SoC information.

Subject: irqchip/gic-v3-its: Macro-ize its_send_single_command

Most ITS commands do operate on a collection object, and require
a SYNC command to be performed on that collection in order to
guarantee the execution of the first command.

With GICv4 ITS, another set of commands perform similar operations
on a VPE object, and a VSYNC operations must be executed to guarantee
their execution.

Given the similarities (post a command, perform a synchronization
operation on a sync object), it makes sense to reuse the same
mechanism for both class of commands.

Let's start with turning its_send_single_command into a huge macro
that performs the bulk of the work, and a set of helpers that
make this macro usable for the GICv3 ITS commands.

Subject: irqchip/gic-v3-its: Generalize LPI configuration

We're are going to need to change a bit more than just the enable
bit in the LPI property table in the future. So let's change the
LPI configuration funtion to take a set of bits to be cleared,
and a set of bits to be set.

This way, we'll be able to use it when a guest updates an LPI
property (priority, for example).

Subject: s390/dasd: Change unsigned long long to unsigned long
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unsigned long long and unsigned long were different in size for 31-bit.
For 64-bit the size for both datatypes is 8 Bytes and since the support
for 31-bit is long gone we can clean up a little and change everything
to unsigned long.
Change get_phys_clock() along the way to accept unsigned long as well so
that the DASD code can be consistent.

Subject: iommu/pamu: Fix PAMU boot crash

Commit 68a17f0be6fe introduced an initialization order
problem, where devices are linked against an iommu which is
not yet initialized. Fix it by initializing the iommu-device
before the iommu-ops are registered against the bus.

Reported-by: Michael Ellerman <mpe@ellerman.id.au>
Fixes: 68a17f0be6fe ('iommu/pamu: Add support for generic iommu-device')

Subject: skd: error pointer dereference in skd_cons_disk()

My initial impulse was to check for IS_ERR_OR_NULL() but when I looked
at this code a bit more closely, we should only need to check for
IS_ERR().

The blk_mq_alloc_tag_set() returns negative error codes and zero on
success so we can just do an "if (rc) goto err_out;".  It's better to
preserve the error code anyhow.  The blk_mq_init_queue() returns error
pointers on failure, it never returns NULL.  We can also remove the
"q = NULL;" at the start because that's no longer needed.

Subject: mtd: nand: Fix various memory leaks in core

The nand_scan_ident() function is not expected to allocate resources,
and people are usually not calling nand_cleanup() if something fails
between nand_scan_ident() and nand_scan_tail().

Move all functions that may allocate resource to the nand_scan_tail()
path to prevent such resource leaks.

Subject: mtd: nand: remove hard-coded NAND ids length

This commit removes hard-coded '8' used for looping into
struct nand_chip.id.data array.

NAND_MAX_ID_LEN has been introduced by Artem Bityutskiy in
53552d22bfe1f for defining ids length in nand_flash_ids[] list.

This commit unifies ids length in nand base driver.

The configuration for BCH is not correct in the current driver.
The ECC_CFG_ECC_DISABLE bit defines whether to enable or disable the
BCH ECC in which

	0x1 : BCH_DISABLED
	0x0 : BCH_ENABLED

But currently host->bch_enabled is being assigned to BCH_DISABLED.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the compatible “qcom,nandcs” is being used for each
connected NAND device to support for multiple NAND devices in the
same bus. The same thing can be achieved by looking reg property
for each sub nodes which contains the chip select number so this
patch removes the use of “qcom,nandcs” for specifying NAND device
sub nodes.

Since there is no user for this driver currently in so
changing compatible string is safe.

Subject: mtd: nand: qcom: reorganize nand page read

Each NAND page consist of multiple codewords. Following is
sequence for NAND page read according to hardware guide.

1. Program Power-up configuration, page row, page column
address and flash configuration registers.
2. Write NAND_FLASH_CMD followed by NANC_EXEC_CMD for each
codeword.
3. Read NAND_FLASH_STATUS for each codeword.

The step 1 should be done once for each page and step 2,3 should
be done for each codeword.

Currently, all the 3 steps are being done for each codeword which
is wrong. Now this patch reorganizes read page functions to
configure page specific register once and per codeword specific
registers for each NAND ECC step.

Subject: mtd: nand: qcom: reorganize nand page write

Each NAND page consist of multiple codewords. Following is
sequence for NAND page write according to hardware guide.

1. Program Power-up configuration, page row, page column
   address and flash configuration registers.
2. Write NAND_FLASH_CMD followed by NANC_EXEC_CMD for each
   codeword.
3. Read NAND_FLASH_STATUS for each codeword.

The step 1 should be done once for each page and step 2,3 should
be done for each codeword.

Currently, all the 3 steps are being done for each codeword which
is wrong. Now this patch reorganizes page write functions to
configure page specific register once and per codeword specific
registers for each NAND ECC step.

The memset in clear_read_regs is overhead. All the register data
will be filled by DMA during NAND operation so making these
register variables zero is not required.

Subject: mtd: nand: qcom: reorganize nand devices probing

The NAND controller can support multiple NAND devices having different
page sizes. Future code will require us to allocate memory based on the
maximum number of codewords among all the devices. We reorganize the
NAND device probing such that the ONFI parameters are first read for
each connected device to identify the maximum number of codewords
possible, and only then proceed with MTD device registration (i.e, call
nand_scan_tail and mtd_device_register).

This is a reorganization of the existing code and will not change any
functionality.

Subject: mtd: orion-nand: fix build error with ARMv4

orion_nand_read_buf uses an inline assembly with the "ldrd"
instruction, which is only available from ARMv5 upwards. This
used to be fine, since all users have an ARMv5 or ARMv7 CPU,
but now we can also build a multiplatform kernel with ARMv4
support enabled in addition to the "kirkwood" (mvebu) platform.

This provides an alternative to call the readsl() function that
is supposed to have the same effect and is also optimized for
performance.

I first posted a version of this patch back in 2014, and there
was some discussion about it then. This fixes the bugs identified
back then and should be a reasonable alternative for the rare
corner case.

Subject: mtd: nand: sunxi: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Subject: mtd: nand: mxc: Fix mxc_v1 ooblayout

Commit a894cf6c5a82 ("mtd: nand: mxc: switch to mtd_ooblayout_ops")
introduced a bug in the OOB layout description. Even if the driver claims
that 3 ECC bytes are reserved to protect 512 bytes of data, it's actually
5 ECC bytes to protect 512+6 bytes of data (some OOB bytes are also
protected using extra ECC bytes).

Fix the mxc_v1_ooblayout_{free,ecc}() functions to reflect this behavior.

Subject: mtd: nand: hynix: add support for 20nm NAND chips

According to the datasheet of the H27UCG8T2BTR the NAND Technology field
(6th byte of the "Device Identifier Description", bits 0-2) the
following values are possible:
- 0x0 = 48nm
- 0x1 = 41nm
- 0x2 = 32nm
- 0x3 = 26nm
- 0x4 = 20nm
- (all others are reserved)

Fix this by extending the mask for this field to allow detecting value
0x4 (20nm) as valid NAND technology.
Without this the detection of the ECC requirements fails, because the
code assumes that the device is a 48nm device (0x4 & 0x3 = 0x0) and
aborts with "Invalid ECC requirements" because it cannot map the "ECC
Level". Extending the mask makes the ECC requirement detection code
recognize this chip as <= 26nm and sets up the ECC step size and ECC
strength correctly.

Subject: mtd: nand: atmel: fix of_irq_get() error check

of_irq_get() may return 0 as well as negative error number on failure,
while the driver only checks for the negative values. The driver would
then call devm_request_irq() for IRQ0  in its probe method and never get
a valid interrupt.

Check for 'nc->irq <= 0' instead and return -ENXIO from the driver's probe
if of_irq_get() returned 0.

Subject: mtd: nand: qcom: support for NAND controller properties

Currently driver data is being assigned directly with ECC modes.
Now, the plan is to add more NAND controller versions which will
have different properties. This patch reorganizes the current driver
data assignment by creating NAND controller properties structure
which will contain all properties specific to NAND controller.

Subject: mtd: nand: qcom: add bam property for QPIC NAND controller

The current driver only supports EBI2 NAND controller which uses
ADM DMA. The latest QCOM SoC uses QPIC NAND controller with BAM
DMA. NAND registers and programming sequence are same for EBI2
and QPIC NAND so the same driver can support QPIC NAND also by
adding the BAM DMA support. This patch adds the is_bam in NAND
property which will be checked for determining the DMA engine type.

Subject: mtd: nand: qcom: DMA mapping support for register read buffer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The EBI2 NAND controller directly remaps register read buffer with
dma_map_sg and DMA address of this buffer will be passed to DMA
API’s. While, on QPIC NAND controller, which uses BAM DMA, we read
the controller registers by preparing a BAM command descriptor. This
command descriptor requires the

  - controller register address
  - the DMA address in which we want to store the value read
    back from the controller register.

This command descriptor will be remapped with dma_map_sg
and its DMA address will be passed to DMA API’s. Therefore,
it's required that we also map our register read buffer for
DMA (using dma_map_single). We use the returned DMA address
for preparing entries in our command descriptor.

This patch adds the DMA mapping support for register read
buffer. This buffer will be DMA mapped during allocation
time. Before starting of any operation, this buffer will
be synced for device operation and after operation
completion, it will be synced again for CPU.

Subject: mtd: nand: qcom: allocate BAM transaction

- The BAM transaction is the core data structure which will be used
  for all the data transfers in QPIC NAND. Since the core framework
  in nand_base.c is serializing all the NAND requests so allocating
  BAM transaction before every transfer will be overhead. The memory
  for it be allocated during probe time and before every transfer,
  it will be cleared.

- The BAM transaction contains the array of
  command and data scatter gather list and indexes. For
  every transfer, all the resource will be taken from BAM
  transaction.

- The size of the buffer used for BAM transactions
  is calculated based on the NAND device with the maximum page size,
  among all the devices connected to the
  controller.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. prepare_bam_async_desc is the function which will call
   all the DMA API’s. It will fetch the outstanding scatter gather
   list for passed channel and will do the DMA descriptor formation.
   The DMA flag is dependent upon the type of channel.

2. For ADM DMA, the descriptor is being formed for every DMA
   request so its sgl count will be always 1 while in BAM DMA, the
   clubbing of descriptor is being done to increase throughput.

3. ADM DMA uses only one channel while in BAM DMA, data descriptors
   will be submitted to tx channel (for write) or rx channel
   (for read) and all the registers read/write descriptors in
   command channel.

Subject: mtd: nand: qcom: support for passing flags in DMA helper functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The QPIC NAND BAM has multiple flags to control the transfer. This
patch adds flags parameter in register and data transfer DMA helper
functions and modifies all these functions call with appropriate
flags using following rule

1. Read and write can’t go in single command descriptor so
   separate SGL should be used.
2. For some of the requests, NWD flag should be set in BAM
   DMA descriptor.
3. For Data write, the BAM has internal buffer for each codeword.
   All write request will modify the data in internal buffer and
   this buffer will be flushed to NAND device once EOT flag is set.
   So for all the write requests in single codeword, the EOT should
   be cleared for all tx data descriptors except the last one.

Subject: mtd: nand: qcom: support for read location registers

In EBI2, all codeword data will be read in FLASH_BUF_ACC buffer
and ADM will copy the data from source (FLASH_BUF_ACC) to
destination (memory for data read).

In QPIC, there is no FLASH_BUF_ACC and all the codeword data will
held in QPIC BAM FIFO buffers. It provides multiple READ_LOCATION
registers which will be used for copying the data from FIFO to
memory. The READ_LOCATION register will be used to read a
specific amount of data from a specific offset within the flash
buffer. It supports sequential offset requests. Each request is
composed of the following fields:

a. Offset within the flash buffer from which data should be
   read
b. Amount of data to be read
c. Flag bit specifying the last read request from the flash
   buffer. Following the last read request the NANDc refers to the
   buffer as empty.

Subject: mtd: nand: qcom: erased codeword detection configuration

The NAND controller returns ECC failure during read of completely
erased codeword. The NAND controller has hardware functionality
to detect erased codeword in case of BCH ECC algorithm. The
NAND_ERASED_CW_DETECT_CFG register controls the erased
codeword/page detection controller. This register should be reset
before every page read by setting and clearing bit 0 of
NAND_ERASED_CW_DETECT_CFG.

Subject: mtd: nand: qcom: support for different DEV_CMD register offsets

The FLASH_DEV_CMD registers starting offset is not same in
different QPIC NAND controller versions. This patch adds
the starting offset in NAND controller properties and uses
the same for calculating the actual offset of these registers.

When we switch to configfs interface, each disk could have different
configuration. To prepare for the change, we move most disk setting to a
separate data structure. The existing module parameter interface is
kept. The 'nr_devices' and 'shared_tags' don't make sense for per-disk

From 3bf2bd20734e3e6ffda53719a9c10fb3ee9c5ffa Mon Sep 17 00:00:00 2001
From: Shaohua Li <shli@fb.com>
Date: Mon, 14 Aug 2017 15:04:53 -0700
Subject: nullb: add configfs interface

Add configfs interface for nullb. configfs interface is more flexible
and easy to configure in a per-disk basis.

Configuration is something like this:
mount -t configfs none /mnt

Checking which features the driver supports:
cat /mnt/nullb/features

The 'features' attribute is for future extension. We probably will add
new features into the driver, userspace can check this attribute to find
the supported features.

Create/remove a device:
mkdir/rmdir /mnt/nullb/a

Then configure the device by setting attributes under /mnt/nullb/a, most
of nullb supported module parameters are converted to attributes:
size; /* device size in MB */
completion_nsec; /* time in ns to complete a request */
submit_queues; /* number of submission queues */
home_node; /* home node for the device */
queue_mode; /* block interface */
blocksize; /* block size */
irqmode; /* IRQ completion handler */
hw_queue_depth; /* queue depth */
use_lightnvm; /* register as a LightNVM device */
blocking; /* blocking blk-mq device */
use_per_node_hctx; /* use per-node allocation for hardware context */

Note, creating a device doesn't create a disk immediately. Creating a
disk is done in two phases: create a device and then power on the
device. Next patch will introduce device power on.

Based on original patch from Kyungchan Koh

Subject: nullb: add interface to power on disk

The device created in nullb configfs interface isn't power on by
default. After user configures the device, user can do 'echo 1 >
xxx/nullb/device_name/power' to power on the device, which will create a
disk. the xxx/nullb/device_name/index is the disk index, so if the index
is 2, the new created disk should be named as /dev/nullb2. Note, the
'index' is only valid after disk is power on.

'echo 0 > xxx/nullb/device_name/power' will remove the disk. Note, this
doesn't remove the device. To remove the device, user should do 'rmdir
xxx/nullb/device_name'. Removing the device will remove the disk too.

This adds memory backed store in nullb.

User configure 'memory_backed' attribute for this. By default, nullb
disk doesn't use memory backed store.

Subject: nullb: support discard

discard makes sense for memory backed disk. And also it's useful to test
if upper layer supports dicard correctly.

User configures 'discard' attribute to enable/disable dicard support.

Subject: nullb: bandwidth control

In test, we usually expect controllable disk speed. For example, in a
raid array, we'd like some disks are fast and some are slow. MD RAID
actually has a feature for this. To test the feature, we'd like to make
the disk run in specific speed.

block throttling probably can be used for this purpose, but it requires
cgroup setup. Here we just implement a simple throttling mechanism in
the driver. There is slight fluctuation in the mechanism, but it's good
enough for test.

To configure the bandwidth cap, user sets the 'mbps' attribute. mbps is
MB/s.

Subject: nullb: emulate cache

Software must flush disk cache to guarantee data safety. To check if
software correctly does disk cache flush, we must know the behavior of
disk. But physical disk behavior is uncontrollable. Even software
doesn't do the flush, the disk probably does the flush. This patch tries
to emulate a cache in the test disk.

All write will go to a cache first, when the cache is full, we then
flush some data to disk storage. A flush request will flush all data of
the cache to disk storage. A FUA write will write to memory store
directly and revalidate data in cache. If there is a power failure (by
writing to power attribute, 'echo 0 > disk_name/power'), we discard all
data in the cache, but preserve the data in disk storage. Later we can
power on the disk again as usual (write 1 to 'power' attribute), then we
can check data integrity and very if software does everything correctly.

A new attribute 'cache_size' (in MB) is added to configure cache size.

Based on original patch from Kyungchan Koh

Subject: nullb: badbblocks support

Sometime disk could have tracks broken and data there is inaccessable,
but data in other parts can be accessed in normal way. MD RAID supports
such disks. But we don't have a good way to test it, because we can't
control which part of a physical disk is bad. For a virtual disk, this
can be easily controlled.

This patch adds a new 'badblock' attribute. Configure it in this way:
echo "+1-100" > xxx/badblock, this will make sector [1-100] as bad
blocks.
echo "-20-30" > xxx/badblock, this will make sector [20-30] good

If badblocks are accessed, the nullb disk will return IO error. Other

Subject: firmware: arm_scpi: fix endianness of dev_id in struct dev_pstate_set

scpi_device_{g,s}et_power_state correctly handles the conversion of
endianness for dev_id using cpu_to_le16. However dev_id is declared
as u16 in struct dev_pstate_set which is incorrect.

This patch fixes the endianness of dev_id in dev_pstate_set structure.

Subject: spi: imx: fix little-endian build

The newly added dynamic burst code produces a harmless warning
on big-endian configurations:

drivers/spi/spi-imx.c:284:15: error: unused variable 'bytes_per_word' [-Werror=unused-variable]

  unsigned int bytes_per_word;

This adds another #ifdef around the variable declaration matching
the one on the use.

Subject: dmaengine: ioatdma: Add intr_coalesce sysfs entry

We observed performance increase with DMA copy from memory
to MMIO by changing the interrupt coalescing value to 0.
The previous set value was projected on the C5xxx Xeon
platform and no longer holds true. Removing hard coded
value and providing a tune-able in sysfs in order to allow
user to tune this on a per channel basis. By default this
value will be set to 0.
Example of sysfs variable importing for interrupt coalescing
value from command line:
echo 5> /sys/devices/pci0000:00/0000:00:04.0/dma/dma0chan0/
quickdata/intr_coalesce

Subject: skd: Avoid double completions in case of a timeout

Avoid that normal request completion and the timeout handler can
run concurrently by calling blk_mq_complete_request() instead of
blk_mq_end_request() from skd_end_request(). Avoid that the block
layer can reuse a request while the firmware is still processing
it. Convert skd_softirq_done() to blk-mq. Pass the pointer to
skd_softirq_done() to the block layer core through
blk_mq_ops.complete instead of by calling blk_queue_softirq_done().
Pass the pointer to skd_timed_out() to the block layer core
through blk_mq_ops.timeout instead of by calling
blk_queue_timed_out(). The timeout handler has been tested as
follows:

    echo 1 > /sys/block/skd0/io-timeout-fail &&
    (cd /sys/kernel/debug/fail_io_timeout &&
      echo 100 > probability &&
      echo N > task-filter &&
      echo 1 > times)

Fixes: commit a74d5b76fab9 ("skd: Switch to block layer timeout mechanism")

Subject: skd: Change default interrupt mode to MSI-X

Since MSI support on some motherboards is unreliable, change the
default interrupt mode from MSI to MSI-X. This patch avoids that
the following message appears sporadially in the kernel logs of
my test setup:

do_IRQ: 3.193 No irq handler for vector

Subject: raid5: remove a call to get_start_sect

The block layer always remaps partitions before calling into the
->make_request methods of drivers.  Thus the call to get_start_sect in
in_chunk_boundary will always return 0 and can be removed.

Subject: block: replace bi_bdev with a gendisk pointer and partitions index

This way we don't need a block_device structure to submit I/O.  The
block_device has different life time rules from the gendisk and
request_queue and is usually only available when the block device node
is open.  Other callers need to explicitly create one (e.g. the lightnvm
passthrough code, or the new nvme multipathing code).

For the actual I/O path all that we need is the gendisk, which exists
once per block device.  But given that the block layer also does
partition remapping we additionally need a partition index, which is
used for said remapping in generic_make_request.

Note that all the block drivers generally want request_queue or
sometimes the gendisk, so this removes a layer of indirection all
over the stack.

Subject: drm/amdgpu: Fix huge page updates with CPU
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Correctly detect system memory mappings when using CPU and don't use
huge pages for them.

Avoid incorrectly translating a physical page table GPU address when
splitting a huge page while mapping system memory.

 vblank immediately
MIME-Version: 1.0

For virtual display, it uses software timer to emulate the vsync interrupt,
it doesn't have high precision, so doesn't support disable vblank immediately.

Subject: clk: qcom: msm8916: Fix bimc gpu clock ops

The clock bimc_gpu_clk_src is incorrectly set to use the shared rcg2
ops, which are for RCGs with child branches controlled by different
CPUs.

The result of the incorrect ops is that the GPU's PM runtime may leave
this clock set at a very low rate. Fix this issue by using the correct
rcg2 ops.

the other fields are 0 by clearing the structure beforehand to prevent

Subject: clk: tegra: Re-factor T210 PLLX registration

Tegra210 PLLX uses the same sequences than then PLLC instances. So there
is no need to have a special registration function and ops struct for it.
Simplify the code by changing all references to the Tegra210 PLLX
registration function to the Tegra210 PLLC registration function and
avoid duplicate functionality.

Subject: clk: tegra: Update T210 PLLSS (D2/DP) registration

Remove from Tegra210 PLLSS registration code sections that
- attempt to set PLL minimum rate (unnecessary, and dangerous if PLL
  is already enabled on boot)
- apply pre-Tegra210 defaults settings
- check IDDQ setting (duplicated with Tegra210 PLLSS check defaults)

Replaced setting of reference clock with check that default oscillator
selection is not changed, and failed registration otherwise as validation
was only done with the oscillator as the reference clock.

Reordered registration, so that PLL initialization is called after
VCOmin adjustment.

Subject: clk: tegra: Fix T210 PLLRE registration

Switched Tegra210 PLLRE registration to common PLL ops instead of special
PLLRE ops used on previous Tegra chips. The latter ops do not follow
chip specific PLL frequency table, and do not apply chip specific rate
calculation method.

Removed unnecessary default rate setting that duplicates h/w reset
state, and is overwritten by clock initialization, anyway.

Subject: staging: ccree: save ciphertext for CTS IV

The crypto API requires saving the last blocks of ciphertext
in req->info for use as IV for CTS mode. The ccree driver
was not doing this. This patch fixes that.

The bug was manifested with cts(cbc(aes)) mode in tcrypt tests.

gcc notices a very complicated way to check a value
for being equal to one, and warns about it:

This simplifies this expression to make it more readable
and to make gcc happy.

Subject: Revert "pty: fix the cached path of the pty slave file descriptor in
 the master"

This reverts commit c8c03f1858331e85d397bacccd34ef409aae993c.

It turns out that while fixing the ptmx file descriptor to have the
correct 'struct path' to the associated slave pty is a really good
thing, it breaks some user space tools for a very annoying reason.

The problem is that /dev/ptmx and its associated slave pty (/dev/pts/X)
are on different mounts.  That was what caused us to have the wrong path
in the first place (we would mix up the vfsmount of the 'ptmx' node,
with the dentry of the pty slave node), but it also means that now while
we use the right vfsmount, having the pty master open also keeps the pts
mount busy.

And it turn sout that that makes 'pbuilder' very unhappy, as noted by
Stefan Lippers-Hollmann:

 "This patch introduces a regression for me when using pbuilder
  0.228.7[2] (a helper to build Debian packages in a chroot and to
  create and update its chroots) when trying to umount /dev/ptmx (inside
  the chroot) on Debian/ unstable (full log and pbuilder configuration
  file[3] attached).

  [...]
  Setting up build-essential (12.3) ...
  Processing triggers for libc-bin (2.24-15) ...
  I: unmounting dev/ptmx filesystem
  W: Could not unmount dev/ptmx: umount: /var/cache/pbuilder/build/1340/dev/ptmx: target is busy
          (In some cases useful info about processes that
           use the device is found by lsof(8) or fuser(1).)"

apparently pbuilder tries to unmount the /dev/pts filesystem while still
holding at least one master node open, which is arguably not very nice,
but we don't break user space even when fixing other bugs.

So this commit has to be reverted.

I'll try to figure out a way to avoid caching the path to the slave pty
in the master pty.  The only thing that actually wants that slave pty
path is the "TIOCGPTPEER" ioctl, and I think we could just recreate the
path at that time.

Cleans up sparse warnings:
symbol 'acpi_processor_check_duplicates' was not declared. Should it
be static?

Subject: ACPI: APEI: fix the wrong iteration of generic error status block

The revision 0x300 generic error data entry is different
from the old version, but currently iterating through the
GHES estatus blocks does not take into account this difference.
This will lead to failure to get the right data entry if GHES
has revision 0x300 error data entry.

Update the GHES estatus iteration macro to properly increment using
acpi_hest_get_next(), and correct the iteration termination condition
because the status block data length only includes error data
length.

Convert the CPER estatus checking and printing iteration logic
to use same macro.

Subject: ACPI / sysfs: Extend ACPI sysfs to provide access to boot error
 region

The ACPI sysfs interface provides a way to read each ACPI table from
userspace via entries in /sys/firmware/acpi/tables/

The BERT table simply provides the size and address of the error
record in BIOS reserved memory and users may want access to this
record.

In an earlier age we might have used /dev/mem to retrieve this error
record, but many systems disable /dev/mem for security reasons.

Extend this driver to provide read-only access to the data via a
file in a new directory /sys/firmware/acpi/tables/data/BERT

At the beginning of 'qedf_srr_compl()' and of 'qedf_rec_compl()', we
check if 'orig_io_req' is NULL. If this happens, a NULL pointer
dereference will occur in the error handling path.

Fix it by adding an additional label in the error handling path in order
to avoid this NULL pointer dereference.

Subject: liquidio: change manner of detecting whether or not NIC firmware is
 loaded

In the NIC firmware, the 1-bit flag indicating "firmware is loaded" moved
from SLI_SCRATCH_1 to SLI_SCRATCH_2 (these are Octeon general-purpose
scratch registers).  Make the PF driver conform to this change.

Remove code that sets the "firmware is loaded" flag because it's now the
firmware's job to do that.

In the code that detects whether or not the firmware is loaded, don't just
rely on checking the "firmware is loaded" flag because that may cause a
rare false negative.  Add code that deduces whether or not the firmware is
loaded; that will never give a false negative.

Also bump up driver version to match newer NIC firmware.

Subject: nfp: don't hold PF lock while enabling SR-IOV

Enabling SR-IOV VFs will cause the PCI subsystem to schedule a
work and flush its workqueue.  Since the nfp driver schedules its
own work we can't enable VFs while holding driver load.  Commit
6d48ceb27af1 ("nfp: allocate a private workqueue for driver work")
tried to avoid this deadlock by creating a separate workqueue.
Unfortunately, due to the architecture of workqueue subsystem this
does not guarantee a separate thread of execution.  Luckily
we can simply take pci_enable_sriov() from under the driver lock.

Take pci_disable_sriov() from under the lock too for symmetry.

Subject: nfp: make sure representors are destroyed before their lower netdev

App start/stop callbacks can perform application initialization.
Unfortunately, flower app started using them for creating and
destroying representors.  This can lead to a situation where
lower vNIC netdev is destroyed while representors still try
to pass traffic.  This will most likely lead to a NULL-dereference
on the lower netdev TX path.

Move the start/stop callbacks, so that representors are created/
destroyed when vNICs are fully initialized.

Subject: nfp: avoid buffer leak when representor is missing

When driver receives a muxed frame, but it can't find the representor
netdev it is destined to it will try to "drop" that frame, i.e. reuse
the buffer.  The issue is that the replacement buffer has already been
allocated at this point, and reusing the buffer from received frame
will leak it.  Change the code to put the new buffer on the ring
earlier and not reuse the old buffer (make the buffer parameter
to nfp_net_rx_drop() a NULL).

The patch uses the tso API to implement the tso functionality in Marvell
PPv2 driver.

Using iperf and 10G ports, using TSO shows a significant performance
improvement by a factor 2 to reach around 9.5Gbps in TX; as well as a
significant CPU usage drop (from 25% to 15%).

Subject: mlxsw: spectrum: Offload multichain TC rules

Reflect chain index coming down from TC core and create a ruleset per
chain. Note that only chain 0, being the implicit chain, is bound to the
device for processing. The rest of chains have to be "jumped-to" by
actions.

The functions set_ctrl0 and set_ctrl1 are local to the source and do
not need to be in global scope, so make them static.

Cleans up sparse warnings:
symbol 'set_ctrl0' was not declared. Should it be static?
symbol 'set_ctrl1' was not declared. Should it be static?

Subject: bnxt_en: Do not setup MAC address in bnxt_hwrm_func_qcaps().

bnxt_hwrm_func_qcaps() is called during probe to get all device
resources and it also sets up the factory MAC address.  The same function
is called when SRIOV is disabled to reclaim all resources.  If
the MAC address has been overridden by a user administered MAC
address, calling this function will overwrite it.

Separate the logic that sets up the default MAC address into a new
function bnxt_init_mac_addr() that is only called during probe time.

Lguest seems to be rather unused these days. It has seen only patches
ensuring it still builds the last two years and its official state is
"Odd Fixes".

Remove it in order to be able to clean up the paravirt code.

- * A hypervisor allows multiple Operating Systems to run on a single machine.
- * To quote David Wheeler: "Any problem in computer science can be solved with
- * another layer of indirection."
- *
- * We keep things simple in two ways.  First, we start with a normal Linux
- * kernel and insert a module (lg.ko) which allows us to run other Linux
- * kernels the same way we'd run processes.  We call the first kernel the Host,
- * and the others the Guests.  The program which sets up and configures Guests
- * (such as the example in tools/lguest/lguest.c) is called the Launcher.
- *
- * Secondly, we only run specially modified Guests, not normal kernels: setting
- * CONFIG_LGUEST_GUEST to "y" compiles this file into the kernel so it knows
- * how to be a Guest at boot time.  This means that you can use the same kernel
- * you boot normally (ie. as a Host) as a Guest.
- *
- * These Guests know that they cannot do privileged operations, such as disable
- * interrupts, and that they have to ask the Host to do such things explicitly.
- * This file consists of all the replacements for such low-level native
- * hardware operations: these special Guest versions call the Host.
- *
- * So how does the kernel know it's a Guest?  We'll see that later, but let's
- * just say that we end up here where we replace the native functions various
- * "paravirt" structures with our Guest versions, then boot like normal.

- * Page Table Handling.
- *
- * Now would be a good time to take a rest and grab a coffee or similarly
- * relaxing stimulant.  The easy parts are behind us, and the trek gradually
- * winds uphill from here.
- *
- * Quick refresher: memory is divided into "pages" of 4096 bytes each.  The CPU
- * maps virtual addresses to physical addresses using "page tables".  We could
- * use one huge index of 1 million entries: each address is 4 bytes, so that's
- * 1024 pages just to hold the page tables.   But since most virtual addresses
- * are unused, we use a two level index which saves space.  The cr3 register
- * contains the physical address of the top level "page directory" page, which
- * contains physical addresses of up to 1024 second-level pages.  Each of these
- * second level pages contains up to 1024 physical addresses of actual pages,
- * or Page Table Entries (PTEs).
- *
- * Here's a diagram, where arrows indicate physical addresses:
- *
- * cr3 ---> +---------+
- *	    |  	   --------->+---------+
- *	    |	      |	     | PADDR1  |
- *	  Mid-level   |	     | PADDR2  |
- *	  (PMD) page  |	     | 	       |
- *	    |	      |	   Lower-level |
- *	    |	      |	   (PTE) page  |
- *	    |	      |	     |	       |
- *	      ....    	     	 ....
- *
- * So to convert a virtual address to a physical address, we look up the top
- * level, which points us to the second level, which gives us the physical
- * address of that page.  If the top level entry was not present, or the second
- * level entry was not present, then the virtual address is invalid (we
- * say "the page was not mapped").
- *
- * Put another way, a 32-bit virtual address is divided up like so:
- *
- *  1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
- * |<---- 10 bits ---->|<---- 10 bits ---->|<------ 12 bits ------>|
- *    Index into top     Index into second      Offset within page
- *  page directory page    pagetable page
- *
- * Now, unfortunately, this isn't the whole story: Intel added Physical Address
- * Extension (PAE) to allow 32 bit systems to use 64GB of memory (ie. 36 bits).
- * These are held in 64-bit page table entries, so we can now only fit 512
- * entries in a page, and the neat three-level tree breaks down.
- *
- * The result is a four level page table:
- *
- * cr3 --> [ 4 Upper  ]
- *	   [   Level  ]
- *	   [  Entries ]
- *	   [(PUD Page)]---> +---------+
- *	 		    |  	   --------->+---------+
- *	 		    |	      |	     | PADDR1  |
- *	 		  Mid-level   |	     | PADDR2  |
- *	 		  (PMD) page  |	     | 	       |
- *	 		    |	      |	   Lower-level |
- *	 		    |	      |	   (PTE) page  |
- *	 		    |	      |	     |	       |
- *	 		      ....    	     	 ....
- *
- *
- * And the virtual address is decoded as:
- *
- *         1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
- *      |<-2->|<--- 9 bits ---->|<---- 9 bits --->|<------ 12 bits ------>|
- * Index into    Index into mid    Index into lower    Offset within page
- * top entries   directory page     pagetable page
- *
- * It's too hard to switch between these two formats at runtime, so Linux only
- * supports one or the other depending on whether CONFIG_X86_PAE is set.  Many
- * distributions turn it on, and not just for people with silly amounts of
- * memory: the larger PTE entries allow room for the NX bit, which lets the
- * kernel disable execution of pages and increase security.
- *
- * This was a problem for lguest, which couldn't run on these distributions;
- * then Matias Zabaljauregui figured it all out and implemented it, and only a
- * handful of puppies were crushed in the process!
- *
- * Back to our point: the kernel spends a lot of time changing both the
- * top-level page directory and lower-level pagetable pages.  The Guest doesn't
- * know physical addresses, so while it maintains these page tables exactly
- * like normal, it also needs to keep the Host informed whenever it makes a

-Welcome, friend reader, to lguest.
-
-Lguest is an adventure, with you, the reader, as Hero.  I can't think of many
-5000-line projects which offer both such capability and glimpses of future
-potential; it is an exciting time to be delving into the source!
-
-But be warned; this is an arduous journey of several hours or more!  And as we
-know, all true Heroes are driven by a Noble Goal.  Thus I offer a Beer (or
-equivalent) to anyone I meet who has completed this documentation.
-
-So get comfortable and keep your wits about you (both quick and humorous).
-Along your way to the Noble Goal, you will also gain masterly insight into
-lguest, and hypervisors and x86 virtualization in general.
-
-Our Quest is in seven parts: (best read with C highlighting turned on)
-
-I) Preparation
-	- In which our potential hero is flown quickly over the landscape for a
-	  taste of its scope.  Suitable for the armchair coders and other such
-	  persons of faint constitution.
-
-II) Guest
-	- Where we encounter the first tantalising wisps of code, and come to
-	  understand the details of the life of a Guest kernel.
-
-III) Drivers
-	- Whereby the Guest finds its voice and become useful, and our
-	  understanding of the Guest is completed.
-
-IV) Launcher
-	- Where we trace back to the creation of the Guest, and thus begin our
-	  understanding of the Host.
-
-V) Host
-	- Where we master the Host code, through a long and tortuous journey.
-	  Indeed, it is here that our hero is tested in the Bit of Despair.
-
-VI) Switcher
-	- Where our understanding of the intertwined nature of Guests and Hosts
-	  is completed.
-
-VII) Mastery
-	- Where our fully fledged hero grapples with the Great Question:
-	  "What next?"
-
-make Preparation!
-Rusty Russell.

- * reflect the Guest's.  (See what I mean about weird naming?  Since when do
- * shadows reflect anything?)
- *
- * Anyway, this is the most complicated part of the Host code.  There are seven
- * parts to this:
- *  (i) Looking up a page table entry when the Guest faults,
- *  (ii) Making sure the Guest stack is mapped,
- *  (iii) Setting up a page table entry when the Guest tells us one has changed,
- *  (iv) Switching page tables,

- * To refresh: the GDT is a table of 8-byte values describing segments.  Once

- * Anyway, the GDT entry contains a base (the start address of the segment), a
- * limit (the size of the segment - 1), and some flags.  Sounds simple, and it
- * would be, except those zany Intel engineers decided that it was too boring
- * to put the base at one end, the limit at the other, and the flags in

- * into the Guest.  This means the Switcher would have to know the top of the
- * Guest page table and the page fault handler address.

- * For simplicity, the Guest should only handle the case where the privilege
- * level of the fault is 3 and probably only not present or write faults.  It
- * should also detect recursive faults, and hand the original fault to the

- (___()'`;  Rusty's Remarkably Unreliable Guide to Lguest
- /,    /`      - or, A Young Coder's Illustrated Hypervisor
- \\"--\\    http://lguest.ozlabs.org
-
-Lguest is designed to be a minimal 32-bit x86 hypervisor for the Linux kernel,
-for Linux developers and users to experiment with virtualization with the
-minimum of complexity.  Nonetheless, it should have sufficient features to
-make it useful for specific tasks, and, of course, you are encouraged to fork
-and enhance it (see drivers/lguest/README).
-
-Features:
-
-- Kernel module which runs in a normal kernel.
-- Simple I/O model for communication.
-- Simple program to create new guests.
-- Logo contains cute puppies: http://lguest.ozlabs.org
-
-Developer features:
-
-- Fun to hack on.
-- No ABI: being tied to a specific kernel anyway, you can change anything.
-- Many opportunities for improvement or feature implementation.
-
-Running Lguest:
-
-- The easiest way to run lguest is to use same kernel as guest and host.
-  You can configure them differently, but usually it's easiest not to.
-
-  You will need to configure your kernel with the following options:
-
-  "Processor type and features":
-     "Paravirtualized guest support" = Y
-        "Lguest guest support" = Y
-     "High Memory Support" = off/4GB
-     "Alignment value to which kernel should be aligned" = 0x100000
-        (CONFIG_PARAVIRT=y, CONFIG_LGUEST_GUEST=y, CONFIG_HIGHMEM64G=n and
-         CONFIG_PHYSICAL_ALIGN=0x100000)
-
-  "Device Drivers":
-     "Block devices"
-        "Virtio block driver" = M/Y
-     "Network device support"
-        "Universal TUN/TAP device driver support" = M/Y
-        "Virtio network driver" = M/Y
-           (CONFIG_VIRTIO_BLK=m, CONFIG_VIRTIO_NET=m and CONFIG_TUN=m)
-
-  "Virtualization"
-     "Linux hypervisor example code" = M/Y
-        (CONFIG_LGUEST=m)
-
-- A tool called "lguest" is available in this directory: type "make"
-  to build it.  If you didn't build your kernel in-tree, use "make
-  O=<builddir>".
-
-- Create or find a root disk image.  There are several useful ones
-  around, such as the xm-test tiny root image at
-	  http://xm-test.xensource.com/ramdisks/initrd-1.1-i386.img
-
-  For more serious work, I usually use a distribution ISO image and
-  install it under qemu, then make multiple copies:
-
-	  dd if=/dev/zero of=rootfile bs=1M count=2048
-	  qemu -cdrom image.iso -hda rootfile -net user -net nic -boot d
-
-  Make sure that you install a getty on /dev/hvc0 if you want to log in on the
-  console!
-
-- "modprobe lg" if you built it as a module.
-
-- Run an lguest as root:
-
-      tools/lguest/lguest 64 vmlinux --tunnet=192.168.19.1 \
-        --block=rootfile root=/dev/vda
-
-   Explanation:
-    64: the amount of memory to use, in MB.
-
-    vmlinux: the kernel image found in the top of your build directory.  You
-       can also use a standard bzImage.
-
-    --tunnet=192.168.19.1: configures a "tap" device for networking with this
-       IP address.
-
-    --block=rootfile: a file or block device which becomes /dev/vda
-       inside the guest.
-
-    root=/dev/vda: this (and anything else on the command line) are
-       kernel boot parameters.
-
-- Configuring networking.  I usually have the host masquerade, using
-  "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" and "echo 1 >
-  /proc/sys/net/ipv4/ip_forward".  In this example, I would configure
-  eth0 inside the guest at 192.168.19.2.
-
-  Another method is to bridge the tap device to an external interface
-  using --tunnet=bridge:<bridgename>, and perhaps run dhcp on the guest
-  to obtain an IP address.  The bridge needs to be configured first:
-  this option simply adds the tap interface to it.
-
-  A simple example on my system:
-
-    ifconfig eth0 0.0.0.0
-    brctl addbr lg0
-    ifconfig lg0 up
-    brctl addif lg0 eth0
-    dhclient lg0
-
-  Then use --tunnet=bridge:lg0 when launching the guest.
-
-  See:
-  
-    http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge
-    
-  for general information on how to get bridging to work.
-
-- Random number generation. Using the --rng option will provide a
-  /dev/hwrng in the guest that will read from the host's /dev/random.
-  Use this option in conjunction with rng-tools (see ../hw_random.txt)
-  to provide entropy to the guest kernel's /dev/random.
-
-There is a helpful mailing list at http://ozlabs.org/mailman/listinfo/lguest
-
-Good luck!
-Rusty Russell rusty@rustcorp.com.au.

Subject: rtc: sa1100: make alarms useful

Currently, the driver unregisters the IRQs when the rtc character device is
closed. This means that the device needs to stay open to get alarms while
the usual use case will open the device, set the alarm and close the
device.

Move the IRQ requests to sa1100_rtc_probe() and use the devm managed
versions so we don't need to free them.

Currently, the IRQs are disabled when the rtc character device is closed.
This means that the device needs to stay open to get alarms while the usual
use case will open the device, set the alarm and close the device.

Keep the alarms functional on character device release. Note that the PIE
are never enabled and would anyway be disabled by the core.

Gadget working. Later Tegra generations do not require that quirk. Let's

Subject: wlcore: add missing nvs file name info for wilink8

The following commits:
commit c815fdebef44 ("wlcore: spi: Populate config firmware data")
commit d776fc86b82f ("wlcore: sdio: Populate config firmware data")

Populated the nvs entry for wilink6 and wilink7 only while it is
still needed for wilink8 as well.
This broke user space backward compatibility when upgrading from older
kernels, as the alternate mac address would not be read from the nvs that
is present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin)
causing mac address change of the wlan interface.

This patch fix this and update the structure field with the same default
nvs file name that has been used before.

In addition, some distros hold a default wl1271-nvs.bin in the file
system with a bogus mac address (deadbeef...) that overrides the mac
address that is stored inside the device.
Warn users about this bogus mac address and use the internal mac address

Fixes: c815fdebef44 ("wlcore: spi: Populate config firmware data")
Fixes: d776fc86b82f ("wlcore: sdio: Populate config firmware data")

Subject: rtlwifi: make a couple arrays larger

This is a static checker fix.  "cal_num" is 10.  We're declaring the
tx_dt[] and rx_td[] arrays as 3 element arrays.  The static checker
complains that we do:

	tx_dt[cal] = (vdf_y[1]>>20)-(vdf_y[0]>>20);

"cal" is the iterator and it is in the 0-9 range so it looks like
we could corrupt memory.

ieee80211_ops are not supposed to change at runtime. All functions

const ieee80211_ops. So mark the non-const structs as const.

Subject: net/mlx5: Convert linear search for free index to ida

When allocating a flow table entry, we need to allocate a free index
in the flow group. Currently, this is done by traversing the existing
flow table entries in the flow group, until a free index is found.
Replacing this by using a ida, which allows us to find a free index
much faster.

Subject: net/mlx5: Don't store reserved part in FTEs and FGs

The current code stores fte_match_param in the software representation
of FTEs and FGs. fte_match_param contains a large reserved area at the
bottom of the struct. Since downstream patches are going to hash this
part, we would like to avoid doing so on a reserved part.

When adding a flow table entry (fte) to a flow group (fg), we first
need to check whether this fte exist. In such a case we just merge
the destinations (if possible). Currently, this is done by traversing
the fte list available in a fg. This could take a lot of time when
using large flow groups. Speeding this up by using rhashtable, which
is much faster.

Subject: net/mlx5: Add hash table for flow groups in flow table

When adding a flow table entry (fte) to a flow table (ft), we first
need to find its flow group (fg). Currently, this is done by
traversing a linear list of all flow groups in the flow table.
Furthermore, since multiple flow groups which correspond to the same
fte mask may exist in the same ft, we can't just stop at the first
match. Converting the linear list to rhltable in order to speed things
up.

The last four patches increases the steering rules update rate by a
factor of more than 7 (for insertion of 50K steering rules).

Subject: iwlwifi: pcie: move rx workqueue initialization to
 iwl_trans_pcie_alloc()

Work queues cannot be allocated when a mutex is held because the mutex
may be in use and that would make it sleep.  Doing so generates the
following splat with 4.13+:

[   19.513298] ======================================================
[   19.513429] WARNING: possible circular locking dependency detected
[   19.513557] 4.13.0-rc5+ #6 Not tainted
[   19.513638] ------------------------------------------------------
[   19.513767] cpuhp/0/12 is trying to acquire lock:
[   19.513867]  (&tz->lock){+.+.+.}, at: [<ffffffff924afebb>] thermal_zone_get_temp+0x5b/0xb0
[   19.514047]
[   19.514047] but task is already holding lock:
[   19.514166]  (cpuhp_state){+.+.+.}, at: [<ffffffff91cc4baa>] cpuhp_thread_fun+0x3a/0x210
[   19.514338]
[   19.514338] which lock already depends on the new lock.

This lock dependency already existed with previous kernel versions,
but it was not detected until commit 49dfe2a67797 ("cpuhotplug: Link
lock stacks for hotplug callbacks") was introduced.

Subject: rtc: mxc: avoid disabling interrupts on device close

Currently, the IRQs are disabled when the rtc character device is closed.
This means that the device needs to stay open to get alarms while the usual
use case will open the device, set the alarm and close the device as is
done in rtcwake.

Keep the alarm functional on character device release so the platform can
actually wakeup.

Subject: rtc: remove .open() and .release()

There are no driver left using .open and .release. There is no good use
case for them as there is nothing the character device interface does that
should not be done in the sysfs interface or in-kernel interface.

Remove those callbacks now to avoid future confusion.

We need a larger gart for asics that do not support GPUVM on all
engines (e.g., MM) to make sure we have enough space for all
gtt buffers in physical mode.  Change the default size based on
the asic type.

Set the shadow flag on the shadow and not the parent, always bind shadow BOs
during allocation instead of manually, use the reservation_object wrappers
to grab the lock.

This fixes a couple of issues with binding the shadow BOs as well as correctly
evicting them when memory becomes tight.

When a process is killed we shouldn't submit all waiting jobs, but instead
clean up as fast as possible.

Subject: drm/amdgpu: set sched_hw_submission higher for KIQ (v3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

KIQ doesn't really use the GPU scheduler.  The base
drivers generally use the KIQ ring directly rather than
submitting IBs.  However, amdgpu_sched_hw_submission
(which defaults to 2) limits the number of outstanding
fences to 2.  KFD uses the KIQ for TLB flushes and the
2 fence limit hurts performance when there are several KFD
processes running.

v2: move some expressions to one line
    change KIQ sched_hw_submission to at least 16
v3: bump to 256

Use ttm_bo_mem_space instead of manually allocating GART space.

This allows us to evict BOs when there isn't enought GART space any more.

Subject: PCI: qcom: Use gpiod_set_value_cansleep() to allow reset via
 expanders

The reset GPIO can be connected to a I2C or SPI IO expander, which may
sleep, so it is safer to use the gpiod_set_value_cansleep() variant
instead.

From 244e00071fd8f6ab2768e61f17e23cbbd9b29b21 Mon Sep 17 00:00:00 2001
From: Philipp Zabel <p.zabel@pengutronix.de>
Date: Wed, 19 Jul 2017 17:25:55 +0200
Subject: PCI: qcom: Explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls to
explicitly state whether the driver needs exclusive or shared reset control
behavior. Convert all drivers requesting exclusive resets to the explicit
API call so the temporary transition helpers can be removed.

No functional changes.

From deff11f884f0056d3f3fde2f526aaab70309255f Mon Sep 17 00:00:00 2001
From: Varadarajan Narayanan <varada@codeaurora.org>
Date: Fri, 18 Aug 2017 12:59:51 +0530
Subject: PCI: qcom: Use block IP version for operations

Presently, when support for a new SoC is added, the driver ops structures
and functions are versioned with plain 1, 2, 3 etc.  Instead use the block
IP version number.

Subject: PCI: qcom: Add support for IPQ8074 PCIe controller

Add support for the IPQ8074 PCIe controller.  IPQ8074 supports Gen 1/2, one
lane, two PCIe root complex with support for MSI and legacy interrupts, and
it conforms to PCI Express Base 2.1 specification.

The core init is the similar to the existing SoC, however the clocks and
reset lines differ.

Subject: PCI: Convert to using %pOF instead of full_name()

Now that we have a custom printf format specifier, convert users of
full_name() to use %pOF instead.  This is preparation for removing storing
of the full path string for each node.

Subject: devlink: Add support for dynamic table size

Up until now the dpipe table's size was static and known at registration
time. The host table does not have constant size and it is resized in
dynamic manner. In order to support this behavior the size is changed
to be obtained dynamically via an op.

This patch also adjust the current dpipe table for the new API.

Subject: mlxsw: spectrum_router: Add helpers for neighbor access

This is done as a preparation before introducing the ability to dump the
host table via dpipe, and to count the table size. The mlxsw's neighbor
representative struct stays private to the router module.

Subject: mlxsw: reg: Make flow counter set type enum to be shared

This is done as a preparation before introducing support for neighbor
counters. The flow counter's type enum is used by many registers, yet,
until now it was used only by mgpc and thus it was private. This patch
updates the namespace for more generic usage.

Subject: mlxsw: spectrum_router: Add support for setting counters on neighbors

Add support for setting counters on neighbors based on dpipe's host table
counter status. This patch also adds the ability for getting the counter
value, which will be used by the dpipe host table implementation in the
next patches.

Subject: parisc: Fix up devices below a PCI-PCI MegaRAID controller bridge

A MegaRAID PCI card in my rp5470 acts as PCI-PCI bridge.
Resource allocation for PCI devices behind such a bridge is quite incomplete,
so that syslog reports those warnings:

The patch below tries to improve the resource allocation.

Subject: of/device: Prevent buffer overflow in of_device_modalias()

As of_device_get_modalias() returns the number of bytes that would have
been written to the target string, regardless of how much did fit in the
buffer, it's possible that the returned index points beyond the buffer
passed to of_device_modalias() - causing memory beyond the buffer to be
null terminated.

Fixes: 0634c2958927 ("of: Add function for generating a DT modalias with a newline")

Subject: of/device: Fix of_device_get_modalias() buffer handling

of_device_request_module() calls of_device_get_modalias() with "len" 0,
to calculate the size of the buffer needed to store the result, but due
to integer promotion the ssize_t "len" will be compared as unsigned with
strlen(compat) and the loop will generally never break. This results in
a call to snprintf() with a negative len, which triggers below warning,
followed by a dereference of a invalid pointer:

  [    3.060067] WARNING: CPU: 0 PID: 51 at lib/vsprintf.c:2122 vsnprintf+0x348/0x6d8
  ...
  [    3.060301] [<ffffff800891ede8>] vsnprintf+0x348/0x6d8
  [    3.060308] [<ffffff800891f248>] snprintf+0x48/0x50

  [    3.060322] [<ffffff80086a7cf8>] of_device_request_module+0x20/0x88
  ...

Further more of_device_get_modalias() is supposed to return the number
of bytes needed to store the entire modalias, so the loop needs to
continue accumulate the total size even though the buffer is full.

Finally the function is not expected to ensure space for the NUL, nor
include it in the returned size, so only 1 should be added to the length
of "compat" in the loop (to account for the character 'C').

Subject: md/bitmap: copy correct data for bitmap super

raid5 cache could write bitmap superblock before bitmap superblock is
initialized. The bitmap superblock is less than 512B. The current code will
only copy the superblock to a new page and write the whole 512B, which will
zero the the data after the superblock. Unfortunately the data could include
bitmap, which we should preserve. The patch will make superblock read do 4k
chunk and we always copy the 4k data to new page, so the superblock write will
old data to disk and we don't change the bitmap.

Subject: md/raid5: release/flush io in raid5_do_work()

In raid5, there are scenarios where some ios are deferred to a later
time, and some IO need a flush to complete. To make sure we make
progress with these IOs, we need to call the following functions:

    flush_deferred_bios(conf);
    r5l_flush_stripe_to_raid(conf->log);

Both of these functions are called in raid5d(), but missing in
raid5_do_work(). As a result, these functions are not called
when multi-threading (group_thread_cnt > 0) is enabled. This patch
adds calls to these function to raid5_do_work().

Note for stable branches:

  r5l_flush_stripe_to_raid(conf->log) is need for 4.4+
  flush_deferred_bios(conf) is only needed for 4.11+

Subject: ixgbe: use return codes from ndo_xdp_xmit that are distinguishable

For XDP_REDIRECT the use of return code -EINVAL is confusing, as it is
used in three different cases.  (1) When the index or ifindex lookup
fails, and in the ixgbe driver (2) when link is down and (3) when XDP
have not been enabled.

The return code can be picked up by the tracepoint xdp:xdp_redirect
for diagnosing why XDP_REDIRECT isn't working.  Thus, there is a need
different return codes to tell the issues apart.

I'm considering using a specific err-code scheme for XDP_REDIRECT
instead of using these errno codes.

Subject: remoteproc/davinci: Add support to parse internal memories

The DSP subsystem on OMAP-L13x SoCs has various internal RAM
memories that can accessed from the ARM side. These memories
can be configured to be used as either RAM or Cache.

The Davinci remoteproc driver has been enhanced to parse and
store the kernel mappings for these internal RAM memories.
These mappings can then be used to support direct loading of
text/data into these memories from the remoteproc driver.

Subject: remoteproc/davinci: Add device tree support for OMAP-L138 DSP

The Davinci remoteproc driver currently supports the DSP remoteproc
device created in legacy-style on OMAP-L13x SoCs. The driver has been
enhanced to support the DSP remoteproc device created through Device
Tree now. The current DT support handles the C674x DSP processor
subsystem on OMAP-L138 SoCs.

Subject: remoteproc/keystone: Add support for Keystone 66AK2G SOCs

Add support to the keystone remoteproc driver for managing the
DSP present in the Keystone 2 66AK2G SoC. The 66AK2G SoC has
a Power Management Micro Controller (PMMC) that manages the
individual device's power, clock and reset functionalities.

The keystone remoteproc driver already uses standard frameworks
for reset and clock control, so it doesn't require any significant
modifications other than a new compatible suitable for 66AK2G DSP.

The binding document is also updated to reflect the modified
property values used by the 66AK2G DSP node as compared to the
values used by existing Keystone 2 DSPs.

Subject: IB/core: Avoid accessing non-allocated memory when inferring port
 type

Commit 44c58487d51a ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types")
introduced the concept of type in ah_attr:
 * During ib_register_device, each port is checked for its type which
   is stored in ib_device's port_immutable array.
 * During uverbs' modify_qp, the type is inferred using the port number
   in ib_uverbs_qp_dest struct (address vector) by accessing the
   relevant port_immutable array and the type is passed on to
   providers.

IB spec (version 1.3) enforces a valid port value only in Reset to
Init. During Init to RTR, the address vector must be valid but port
number is not mentioned as a field in the address vector, so its
value is not validated, which leads to accesses to a non-allocated
memory when inferring the port type.

Save the real port number in ib_qp during modify to Init (when the
comp_mask indicates that the port number is valid) and use this value
to infer the port type.

Avoid copying the address vector fields if the matching bit is not set
in the attr_mask. Address vector can't be modified before the port, so
no valid flow is affected.

Subject: IB/mlx5: Always return success for RoCE modify port

CM layer calls ib_modify_port() regardless of the link layer.

For the Ethernet ports, qkey violation and Port capabilities
are meaningless. Therefore, always return success for ib_modify_port
calls on the Ethernet ports.

Subject: IB/cma: Fix erroneous validation of supported default GID type

When rdma_cm is initializing a cma_device it checks if this device
supports the preferred default GID type. This check was done in a wrong way
and therefore sometimes rdma_cm is coming up with default GID type that is
not supported by the device.

Fix that by checking for supported GID type properly.

Subject: pty: Repair TIOCGPTPEER

The implementation of TIOCGPTPEER has two issues.

When /dev/ptmx (as opposed to /dev/pts/ptmx) is opened the wrong
vfsmount is passed to dentry_open.  Which results in the kernel displaying
the wrong pathname for the peer.

The second is simply by caching the vfsmount and dentry of the peer it leaves
them open, in a way they were not previously Which because of the inreased
reference counts can cause unnecessary behaviour differences resulting in
regressions.

To fix these move the ioctl into tty_io.c at a generic level allowing
the ioctl to have access to the struct file on which the ioctl is
being called.  This allows the path of the slave to be derived when
opening the slave through TIOCGPTPEER instead of requiring the path to
the slave be cached.  Thus removing the need for caching the path.

A new function devpts_ptmx_path is factored out of devpts_acquire and
used to implement a function devpts_mntget.   The new function devpts_mntget
takes a filp to perform the lookup on and fsi so that it can confirm
that the superblock that is found by devpts_ptmx_path is the proper superblock.

v2: Lots of fixes to make the code actually work
v3: Suggestions by Linus
    - Removed the unnecessary initialization of filp in ptm_open_peer
    - Simplified devpts_ptmx_path as gotos are no longer required

[ This is the fix for the issue that was reverted in commit
  143c97cc6529, but this time without breaking 'pbuilder' due to
  increased reference counts   - Linus ]

Subject: RDMA/(core, ulp): Convert register/unregister event handler to be
 void

The functions ib_register_event_handler() and
ib_unregister_event_handler() always returned success and they can't fail.

Let's convert those functions to be void, remove redundant checks and
cleanup tons of goto statements.

All callers of acquire_group() passed the same gfp_mask to it
and it is safe to remove it.

Subject: RDMA/usnic: Fix remove address space warning

Sparse tool complains with the following error:
drivers/infiniband/hw/usnic/usnic_ib_main.c:445:16: warning: cast removes
	address space of expression

Fix it by doing casting on correct field and convert function helper which
sets ifaddr to be void, because there are no users who are interested in
returned value.

Subject: RDMA/mthca: Make explicit conversion to 64bit value

The "lg" variable is declared as int so in all places where
this variable is used as a shift operand, the output will be
int too.

This produces the following smatch warning:
drivers/infiniband/hw/mthca/mthca_cmd.c:701 mthca_map_cmd() warn:
	should '1 << lg' be a 64 bit type?

Simple declaration of "1" to be "1ULL" will fix the issue.

Subject: IB/ipoib: Sync between remove_one to sysfs calls that use rtnl_lock

In order to avoid deadlock between sysfs functions (like create/delete
child) and remove_one (both of them are using the sysfs lock and
rtnl_lock) the driver will use a state mutex for sync.

That will fix traces as the following:

Subject: qlge: avoid memcpy buffer overflow

gcc-8.0.0 (snapshot) points out that we copy a variable-length string
into a fixed length field using memcpy() with the destination length,
and that ends up copying whatever follows the string:

    inlined from 'ql_core_dump' at drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:1106:2:
drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:708:2: error: 'memcpy' reading 15 bytes from a region of size 14 [-Werror=stringop-overflow=]
  memcpy(seg_hdr->description, desc, (sizeof(seg_hdr->description)) - 1);

Changing it to use strncpy() will instead zero-pad the destination,
which seems to be the right thing to do here.

The bug is probably harmless, but it seems like a good idea to address
it in stable kernels as well, if only for the purpose of building with
gcc-8 without warnings.

Subject: IB: Avoid ib_modify_port() failure for RoCE devices

IB CM calls ib_modify_port() irrespective of link layer. If the
failure is returned, the mad agent gets unregistered for those
devices. Recently, modify_port() hook was removed from some of the
low level drivers as it was always returning success. This breaks
rdma connection establishment over those devices.
For ethernet devices, Qkey violation and port capabilities are not
applicable. So returning success for RoCE when modify_port hook is
is not implemented.

Subject: IB/mlx5: Expose software parsing for Raw Ethernet QP

Software parsing (SWP) is a feature that can be used to instruct the
device to stop using its internal parser and to parse packets on the
transmit path according to offsets set for each packets.

Through this feature, the device allows the handling of checksum and
LSO by the hardware according to the location of IP and TCP/UDP
headers.

Enable SW parsing on Raw Ethernet send queue by default if firmware
supports it and report these capabilities to user space.

Subject: IB/mlx5: Enable UMR for MRs created with reg_create

This patch is the first step in decoupling UMR usage and
allocation from the MR cache. The only functional change
in this patch is to enables UMR for MRs created with
reg_create.

This change fixes a bug where ODP memory regions that
were not allocated from the MR cache did not have UMR
enabled.

Subject: IB/mlx5: Decouple MR allocation and population flows

mlx5 compatible devices have two ways of populating the MTT
table of an MKEY: using a FW command and using a UMR WQE.

A UMR is much faster, so it should be used whenever possible.
Unfortunately the code today uses UMR only if the MKEY was allocated
from the MR cache.

Fix the code to use UMR even for MKEYs that were allocated using
a FW command.

Subject: IB/mlx5: Fix integer overflow when page_shift == 31

Fix a bug where MR registration fails when mlx5_ib_cont_pages
indicates that the MR can be mapped using 2GB pages (page_shift == 31).

Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters")

Subject: IB/mlx5: Add support for multi underlay QP

Set underlay QPN as part of flow rule when it's applicable.

There is one root flow table in the NIC RX namespace and all the
underlay QPs steer the traffic to this flow table.
In order to prevent QP to get traffic which is not target to its
underlay QP, we need to set the underlay QP number as part of
the steering matching.

Note:
When multicast traffic is sent the QPN filtering is done by the firmware
as some early step. Adding the QPN match on the flow table entry is
wrong as by that time the target QPN holds the multicast address (e.g.
FF(s)) and it won't match.

Set the field to allow posting multi packet send WQEs if hardware
supports this feature. This doesn't mean the send WQEs will be for
multi packet unless the send WQE was prepared according to multi
packet send WQE format.

User space shall use flag MLX5_IB_ALLOW_MPW to check if hardware
supports MPW and allows MPW in SQ context.

Subject: rpmsg: virtio_rpmsg_bus: fix sg_set_buf() when addr is not a valid
 kernel address

To specify memory for remoteproc, we declare (dma_declare_coherent_memory())
an area which is ioremap'ed to the vmalloc area.  However, this address is
not a kernel address so virt_addr_valid(buf) fails.

Subject: Input: ALPS - fix two-finger scroll breakage in right side on ALPS
 touchpad

Fixed the issue that two finger scroll does not work correctly
on V8 protocol. The cause is that V8 protocol X-coordinate decode
is wrong at SS4 PLUS device. I added SS4 PLUS X decode definition.

Mote notes:
the problem manifests itself by the commit e7348396c6d5 ("Input: ALPS
- fix V8+ protocol handling (73 03 28)"), where a fix for the V8+
protocol was applied.  Although the culprit must have been present
beforehand, the two-finger scroll worked casually even with the
wrongly reported values by some reason.  It got broken by the commit
above just because it changed x_max value, and this made libinput
correctly figuring the MT events.  Since the X coord is reported as
falsely doubled, the events on the right-half side go outside the
boundary, thus they are no longer handled.  This resulted as a broken
two-finger scroll.

One finger event is decoded differently, and it didn't suffer from
this problem.  The problem was only about MT events. --tiwai

Subject: cpufreq: dt-platdev: Automatically create cpufreq device with OPP v2

The initial idea of creating the cpufreq-dt-platdev.c file was to keep a
list of platforms that use the "operating-points" (V1) bindings and
create cpufreq device for them only, as we weren't sure which platforms
would want the device to get created automatically as some had their own
cpufreq drivers as well, or wanted to initialize cpufreq after doing
some stuff from platform code.

But that wasn't the case with platforms using "operating-points-v2"
property. We wanted the device to get created automatically without the
need of adding them to the whitelist. Though, we will still have some
exceptions where we don't want to create the device automatically.

Rename the earlier platform list as *whitelist* and create a new
*blacklist* as well.

The cpufreq-dt device will get created if:
- The platform is there in the whitelist OR
- The platform has "operating-points-v2" property in CPU0's DT node and
  isn't part of the blacklist .

Subject: cpufreq: dt-platdev: Drop few entries from whitelist

Drop few ARM (32 and 64 bit) platforms from the whitelist which always
use "operating-points-v2" property from their DT. They should continue
to work after this patch.

Tested on Hikey platform (only the "hisilicon,hi6220" entry).

 path

If 'dev_pm_opp_set_supported_hw()' fails, 'opp_data->opp_node' refcount
will be decremented 2 times.
One, just a few lines above, and another one in the error handling path.

Fix it by simply moving the 'of_node_put' call of the normal path.

Subject: phy: ralink: fix 64-bit build warning

Casting between an 'int' and a pointer causes a warning on
64-bit architectures in compile-testing this driver:

drivers/phy/ralink/phy-ralink-usb.c: In function 'ralink_usb_phy_probe':
drivers/phy/ralink/phy-ralink-usb.c:195:13: error: cast from pointer to
integer of different size [-Werror=pointer-to-int-cast]

This changes the code to cast to uintptr_t instead. This is
guaranteed to do what we want on all architectures and avoids
the warning.

Subject: net: systemport: Free DMA coherent descriptors on errors

In case bcm_sysport_init_tx_ring() is not able to allocate ring->cbs, we
would return with an error, and call bcm_sysport_fini_tx_ring() and it
would see that ring->cbs is NULL and do nothing. This would leak the
coherent DMA descriptor area, so we need to free it on error before
returning.

Subject: tg3: Be drop monitor friendly

tg3_tx() does the normal packet TX completion,
tigon3_dma_hwbug_workaround() and tg3_tso_bug() both need to allocate a
new SKB that is suitable to workaround HW bugs, and finally
tg3_free_rings() is doing ring cleanup. Use dev_consume_skb_any() for
these 3 locations to be SKB drop monitor friendly.

Subject: drm/exynos/dsi: refactor panel detection logic

Description of drm_helper_hpd_irq_event clearly states that drivers
supporting hotplug events per connector should use different helper -
drm_kms_helper_hotplug_event. To achieve it following changes have
been performed:
- moved down all DSI ops - they require exynos_dsi_disable function
to be defined earlier,
- simplified exynos_dsi_detect - there is no real detection, it just
returns if panel is attached,
- DSI attach/detach callbacks attaches/detaches DRM panel and sets
connector status and other context fields accordingly, all this is
performed under mutex, as these callbacks are asynchronous.

Subject: drm/exynos/dsi: propagate info about command mode from panel

mipi_dsi framework provides information about panel's mode of work.
This info should be propagated upstream to configure all elements of
the pipeline. As CRTC is the common denominator of the pipeline we can
put such info into its structures.

Subject: scsi: hisi_sas: add reset handler for v3 hw

Use ACPI "_RST" method to reset the controller, since FLR is not
supported.

Function hisi_sas_stop_phys() is introduced to remove some code
duplication.

Subject: scsi: qedi: Limit number for CQ queues.

[qed_sp_iscsi_func_start:189(host_7-0)]Cannot satisfy CQ amount. Queues
requested 8, CQs available 4. Aborting function start

Above condition will resolve as management firmware is capable of
telling us the number of CQs available for a given PF, qed will
communicate the same number to qedi, So that qedi will know how much CQs
are allowed.

Subject: scsi: virtio: Reduce BUG if total_sg > virtqueue size to WARN.

If using indirect descriptors, you can make the total_sg as large as you
want.  If not, BUG is too serious because the function later returns
-ENOSPC.

Subject: scsi: virtio: virtio_scsi: Set can_queue to the length of the
 virtqueue.

Since switching to blk-mq as the default in commit 5c279bd9e406
("scsi: default to scsi-mq"), virtio-scsi LUNs consume about 10x as
much kernel memory.

qemu currently allocates a fixed 128 entry virtqueue.  can_queue
currently is set to 1024.  But with indirect descriptors, each command
in the queue takes 1 virtqueue entry, so the number of commands which
can be queued is equal to the length of the virtqueue.

Note I intend to send a patch to qemu to allow the virtqueue size to be
configured from the qemu command line.

Subject: scsi: make 'state' device attribute pollable

While the 'state' attribute can (and will) change occasionally,
calling 'poll()' or 'select()' on it fails as sysfs is never
notified that the state has changed.
With this patch calling 'poll()' or 'select()' will work
properly.

-Detecting drive failures:
--------------------------
-
-To get the status of logical volumes and to detect physical drive
-failures, you can use the cciss_vol_status program found here:
-http://cciss.sourceforge.net/#cciss_utils
-
-Device Naming:
---------------
-
-If nodes are not already created in the /dev/cciss directory, run as root:
-
-# cd /dev
-# ./MAKEDEV cciss
-
-You need some entries in /dev for the cciss device.  The MAKEDEV script
-can make device nodes for you automatically.  Currently the device setup
-is as follows:
-
-Major numbers:
-	104	cciss0	
-	105	cciss1	
-	106	cciss2
-	105	cciss3
-	108	cciss4
-	109	cciss5
-	110	cciss6
-	111	cciss7
-
-Minor numbers:
-        b7 b6 b5 b4 b3 b2 b1 b0
-        |----+----| |----+----|
-             |           |
-             |           +-------- Partition ID (0=wholedev, 1-15 partition)
-             |
-             +-------------------- Logical Volume number
-
-The device naming scheme is:
-/dev/cciss/c0d0			Controller 0, disk 0, whole device
-/dev/cciss/c0d0p1		Controller 0, disk 0, partition 1
-/dev/cciss/c0d0p2		Controller 0, disk 0, partition 2
-/dev/cciss/c0d0p3		Controller 0, disk 0, partition 3
-
-/dev/cciss/c1d1			Controller 1, disk 1, whole device
-/dev/cciss/c1d1p1		Controller 1, disk 1, partition 1
-/dev/cciss/c1d1p2		Controller 1, disk 1, partition 2
-/dev/cciss/c1d1p3		Controller 1, disk 1, partition 3
-
-CCISS simple mode support
--------------------------
-
-The "cciss_simple_mode=1" boot parameter may be used to prevent the driver
-from putting the controller into "performant" mode. The difference is that
-with simple mode, each command completion requires an interrupt, while with
-"performant mode" (the default, and ordinarily better performing) it is
-possible to have multiple command completions indicated by a single
-interrupt.
-
-SCSI tape drive and medium changer support
-------------------------------------------
-
-SCSI sequential access devices and medium changer devices are supported and 
-appropriate device nodes are automatically created.  (e.g.  
-/dev/st0, /dev/st1, etc.  See the "st" man page for more details.) 
-You must enable "SCSI tape drive support for Smart Array 5xxx" and 
-"SCSI support" in your kernel configuration to be able to use SCSI
-tape drives with your Smart Array 5xxx controller.
-
-Additionally, note that the driver will engage the SCSI core at init
-time if any tape drives or medium changers are detected.  The driver may
-also be directed to dynamically engage the SCSI core via the /proc filesystem
-entry which the "block" side of the driver creates as
-/proc/driver/cciss/cciss* at runtime.  This is best done via a script.
-
-For example:
-
-	for x in /proc/driver/cciss/cciss[0-9]*
-	do
-		echo "engage scsi" > $x
-	done
-
-Once the SCSI core is engaged by the driver, it cannot be disengaged 
-(except by unloading the driver, if it happens to be linked as a module.)
-
-Note also that if no sequential access devices or medium changers are
-detected, the SCSI core will not be engaged by the action of the above
-script.
-
-Hot plug support for SCSI tape drives
--------------------------------------
-
-Hot plugging of SCSI tape drives is supported, with some caveats.
-The cciss driver must be informed that changes to the SCSI bus
-have been made.  This may be done via the /proc filesystem.
-For example:
-
-	echo "rescan" > /proc/scsi/cciss0/1
-
-This causes the driver to query the adapter about changes to the
-physical SCSI buses and/or fibre channel arbitrated loop and the
-driver to make note of any new or removed sequential access devices
-or medium changers.  The driver will output messages indicating what 
-devices have been added or removed and the controller, bus, target and 
-lun used to address the device.  It then notifies the SCSI mid layer
-of these changes.
-
-Note that the naming convention of the /proc filesystem entries 
-contains a number in addition to the driver name.  (E.g. "cciss0" 
-instead of just "cciss" which you might expect.)
-
-Note: ONLY sequential access devices and medium changers are presented 
-as SCSI devices to the SCSI mid layer by the cciss driver.  Specifically, 
-physical SCSI disk drives are NOT presented to the SCSI mid layer.  The 
-physical SCSI disk drives are controlled directly by the array controller 
-hardware and it is important to prevent the kernel from attempting to directly
-access these devices too, as if the array controller were merely a SCSI 
-controller in the same way that we are allowing it to access SCSI tape drives.
-
-SCSI error handling for tape drives and medium changers
--------------------------------------------------------
-
-The linux SCSI mid layer provides an error handling protocol which
-kicks into gear whenever a SCSI command fails to complete within a
-certain amount of time (which can vary depending on the command).
-The cciss driver participates in this protocol to some extent.  The
-normal protocol is a four step process.  First the device is told
-to abort the command.  If that doesn't work, the device is reset.
-If that doesn't work, the SCSI bus is reset.  If that doesn't work
-the host bus adapter is reset.  Because the cciss driver is a block
-driver as well as a SCSI driver and only the tape drives and medium
-changers are presented to the SCSI mid layer, and unlike more 
-straightforward SCSI drivers, disk i/o continues through the block
-side during the SCSI error recovery process, the cciss driver only
-implements the first two of these actions, aborting the command, and
-resetting the device.  Additionally, most tape drives will not oblige 
-in aborting commands, and sometimes it appears they will not even 
-obey a reset command, though in most circumstances they will.  In
-the case that the command cannot be aborted and the device cannot be 
-reset, the device will be set offline.
-
-In the event the error handling code is triggered and a tape drive is
-successfully reset or the tardy command is successfully aborted, the 
-tape drive may still not allow i/o to continue until some command
-is issued which positions the tape to a known position.  Typically you
-must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example)
-before i/o can proceed again to a tape drive which was reset.
-
-There is a cciss_tape_cmds module parameter which can be used to make cciss
-allocate more commands for use by tape drives.  Ordinarily only a few commands
-(6) are allocated for tape drives because tape drives are slow and
-infrequently used and the primary purpose of Smart Array controllers is to
-act as a RAID controller for disk drives, so the vast majority of commands
-are allocated for disk devices.  However, if you have more than a few tape
-drives attached to a smart array, the default number of commands may not be
-enough (for example, if you have 8 tape drives, you could only rewind 6
-at one time with the default number of commands.)  The cciss_tape_cmds module
-parameter allows more commands (up to 16 more) to be allocated for use by
-tape drives.  For example:
-
-        insmod cciss.ko cciss_tape_cmds=16
-
-Or, as a kernel boot parameter passed in via grub:  cciss.cciss_tape_cmds=8

As the cciss driver has been removed there are no overlapping

Subject: scsi: qedf: Use granted MAC from the FCF for the FCoE source address
 if it is available.

Currently in the driver we've been using the fc_fcoe_set_mac() function to
set the source MAC for FCoE traffic.  This works well in most cases as it
uses the spec. default FCF-MAC.  However, if the administrator changes the
FCF-MAC switch, then any FCoE traffic we send will be dropped by the
switch.

Instead we should check the granted MAC from the FLOGI payload and use that
address if it is present.  Otherwise, fall back to using the the default
FCF-MAC and the fabric ID of the port as the FCoE MAC address.

Once this address is known we need to set it when doing non-offload
traffic, offload traffic and setting the data_src_address libfcoe uses for
FIP keep alive messages.

Subject: scsi: qedf: Corrent VLAN tag insertion in fallback VLAN case.

Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to
which whether to insert a VLAN tag in FIP frames (except for FIP VLAN
request which is explicitly sent out untagged at least from the driver's
point of view).

When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which
makes the qedf_fip_send function insert the VLAN.  However when we exhaust
our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means
that the driver will not tag the FIP frame with the correct VLAN ID.  The
result that was observed on the wire is that some entity either in the LL2
or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation
to fail.

The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert
attribute to decide whether to tag frames with the FIP/FCoE VLAN.  Instead
it unilaterially tags the offload frames with the VLAN ID stored in
qedf->vlan_id. This is the correct behavior so the driver can guarantee
that non-offload FIP frames go out with the correct VLAN ID.

Also use the Linux network layer helpers instead of doing the VLAN insert
manually.

Also fix setting the fallback VLAN so that it used the module parameter and
is not hardcoded to 1002 (though 1002 is the default).

[mkp: fixed typo]

pnp_device_id are not supposed to change at runtime. All functions

pnp_device_id. So mark the non-const structs as const.

If scsi_host_template->host_reset is NULL and the user requests an

-EINVAL will be returned even though the "adapter" argument is perfectly
valid.

Change this so that we only return -EINVAL if the provided string is

return -EOPNOTSUPP.

Subject: scsi: sg: recheck MMAP_IO request length with lock held

Commit 1bc0eb044615 ("scsi: sg: protect accesses to 'reserved' page
array") adds needed concurrency protection for the "reserve" buffer.
Some checks that are initially made outside the lock are replicated once
the lock is taken to ensure the checks and resulting decisions are made
using consistent state.

The check that a request with flag SG_FLAG_MMAP_IO set fits in the
reserve buffer also needs to be performed again under the lock to ensure
the reserve buffer length compared against matches the value in effect
when the request is linked to the reserve buffer.  An -ENOMEM should be
returned in this case, instead of switching over to an indirect buffer
as for non-MMAP_IO requests.

Take f_mutex around mmap() processing to protect against races with the
SG_SET_RESERVED_SIZE ioctl.  Ensure the reserve buffer length remains
consistent during the mapping operation, and set the "mmap called" flag
to prevent further changes to the reserved buffer size as an atomic
operation with the mapping.

Subject: scsi: megaraid_sas: Use synchronize_irq in target reset case

Similar to task abort case, use synchronize_irq API in target reset
case.  Also, remove redundant call to megasas_complete_cmd_dpc_fusion
after calling megasas_sync_irqs in task abort case.

Subject: scsi: megaraid_sas: Call megasas_complete_cmd_dpc_fusion every 1
 second while there are pending commands

megasas_wait_for_outstanding_fusion checks for pending commands every 1
second. But megasas_complete_cmd_dpc_fusion is only called every 5
seconds.  If the commands are already completed by firmware, there is an
additional delay of 5 seconds before driver will process completion for
these commands.

Subject: scsi: megaraid_sas: use vmalloc for crash dump buffers and driver's
 local RAID map

Driver's local RAID map is accessed frequently. We will first try to get
memory from __get_free_pages. If this fails, fall back to using vmalloc.
For crash dump buffers always prefer vmalloc.

Subject: scsi: megaraid_sas: Return pended IOCTLs with cmd_status
 MFI_STAT_WRONG_STATE in case adapter is dead

After a kill adapter, since the cmd_status is not set, the IOCTLs will
be hung in driver resulting in application hang.  Set cmd_status
MFI_STAT_WRONG_STATE when completing pended IOCTLs.

Subject: scsi: qla2xxx: Add command completion for error path

The driver held spinlocks during callbacks for NVME errors which
resulted in a deadlock because recovery LS cmds needed the same lock.

Subject: scsi: qla2xxx: Handle PCIe error for driver

Driver will perform following

- Set PFLG_DRIVER_REMOVING flag and do not disable PCIe error reporting
  during adapter shutdown.
- If PCIe device count is already zero, return correct error type from
  PCI error interface.
- When device is offline, return correct error type from PCIe error
  path.
- If there is board disable thread active during shutdown and PCIe
  device count is zero then cancel scheduling board disable thread
  during shutdown and return.

Subject: scsi: qla2xxx: Use BIT_6 to acquire FAWWPN from switch

If FA-WWPN feature disabled on the switch side and enabled for the
adapter, then driver would update the port name with switch port name.

This patch fixes issue by checking correct BIT flag to validate.

Subject: scsi: qla2xxx: Add ability to autodetect SFP type

SFP can come in 2 formats: short range/SR and long range/LR.  For LR,
user the can increase the number of Buffer to Buffer credits between end
points via Cavium's command line tool.  By default, FW uses a lower BB
Credit value optimized for SR.  This patch will read the SFP for each
link up event and during chip reset sequence. If the SFP type and
setting are mismatch, then the chip is reset 1 time to use the
appropriate setting.

Subject: scsi: qla2xxx: Cleanup NPIV host in target mode during config
 teardown

When we tear down the NPIV host configuration in target mode, the
qla_tgt struct was left dangling on the global list. This patch cleans
up link list and frees memory.

Subject: scsi: qla2xxx: Increase ql2xmaxqdepth to 64

ql2xmaxqdepth is the module parameter that seeds the per target
queue depth in the Scsi midlayer (sdev->queue_depth). Performance
testing revealed that increasing this value would improve IOPS
numbers under certain workloads.

Subject: scsi: qla2xxx: Do not call abort handler function during chip reset

If there are IO's running and host reset or chip reset is triggered,
IO's can fail due to rport time out. During chip reset recovery process,
driver notifies the transport layer that remote port no longer exist, by
calling fc_remote_port_delete(). When this function is called, it
actually delays deletion by "blocking" it. It sets the remote port state
to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING.  When
driver tries to abort the command by calling its abort handler function,
abort handler will wait until remote port state is blocked state or wait
for dev_loss_tmo time. Due to this blocking, rport times out and results
in an IO failure. This patch adds a check for any active reset process
before calling abort handler function.

Message "0271 Illegal State Transition: node" seen in logs, all luns are
unuseable for that target.

A window exists in the rcv_plogi path where if the state is plogi issue
but the driver has not issued a plogi, then two reglogins will be sent
for the same RPI. The first one to complete will advance the state to
prli issue the second one will be detected as an illegal state, and
leave the node in an unusable state.

Correct the completion routine for the PLOGI ACC that detects the state
change when the driver starts discovery on the node again and drop the
REGLOGIN mailbox command.

Subject: scsi: lpfc: Fix loop mode target discovery

The driver does not discover targets when in loop mode.

The NLP type is correctly getting set when a fabric connection is
detected but, not for loop. The unknown NLP type means that the driver
does not issue a PRLI when in loop topology. Thus target discovery
fails.

Fix by checking the topology during discovery.  If it is loop, set the
NLP FC4 type to FCP.

Subject: scsi: lpfc: Fix rediscovery on switch blade pull

When the switch blade is pulled out then plugged back in, the driver
does not issue a PLOGI to the target

When the switch blade is pulled out, it does not reset the link. The
driver ends up issuing a LOGO to the target, and finally sees devloss.
Since the driver believes that a LOGO is outstanding, it does not issue
a PLOGI to the target upon link up

Correct by placing the ndlp in UNUSED state When devloss happens in
LOGO_ISSUE state.

lpfc oops when it discovers a NVME target but is configured for SCSI

The localport is not valid so it should not have been referenced.

Subject: scsi: lpfc: Correct return error codes to align with nvme_fc
 transport

Modify driver return error codes to align with host nvme transport.

Driver isn't returning Exxx error codes to properly reflect out of
resource or connectivity conditions (-EBUSY), yet there were hard error
conditions returning -EBUSY.

Ensure the following situations return the proper return code:

 - Temporary failures or temporary resource availability: -EBUSY

 - Connectivity issues: -ENODEV

All others are treated as hard errors and return an -Exxx value that
indicates the type of error.

Also, lpfc_sli4_issue_wqe() was modified to not translate error from
-Exxx to WQE state.  This allows lpfc_nvme_fcp_io_submit() routine to
just return whatever -E value was returned from other routines.

Subject: scsi: lpfc: Fix handling of FCP and NVME FC4 types in Pt2Pt topology

After link bounce in a NVME Pt2Pt config, the driver managed to map the
same nport twice, resulting in multiple device nodes for the same
namespace.

In Pt2Pt, the driver must send PRLI's for both (scsi) FCP and NVME
rather than using fabric aids. The driver was inconsistent on handling
various PRLI completions, especially rejects, which had reject codes
cross the different protocol PRLI completions.

Fixed to perform the following: if nvmet mode (fc port can only be a
nvme target) - rejects all unsolicitly FCP PRLI's. Never issues a FCP
PRLI.

The multiple protocol PRLI's are sent simultaneously. However, driver
will now only state transition after both PRLI's are complete. New flags
were added to aid tracking the responses from the different PRLI's.

Subject: scsi: lpfc: Fix duplicate NVME rport entries and namespaces.

After lip, the driver sometimes would have two rports for the same
device, allowing the namespaces to be duplicated by nvme.

In lpfc_plogi_confirm_nport() the driver was not swapping the nrport
maintained by the ndlp's undergoing address swapping. This allowed the
2nd rport to sneak in as it was considered a separate device.

This patch adds the fixes to Swap the nrport in each ndlp and take care
of the reference counts on the ndlps similar to FCP rports.

Subject: scsi: lpfc: Fix crash in lpfc nvmet when fc port is reset

In adapter reset tests, an oops was seen with a NULL pointer in
lpfc_free_rq_buffer+0x20/0x60

The driver is failing to properly repost the nvmet sgl list when
recovering from the reset. Thus the driver eventually trys to walk an
errant buffer list.

Corrected the sgl buffer recovery as well as strengthening the
initialization of the bufferlist.

Subject: scsi: lpfc: Fix NVME PRLI handling during RSCN

A race condition was found whereby the initiator would receive the RSCN
for a new NVME device before it had a chance to register its FC4 support
with the fabric. Thus, when queried by the initiator, it would see that
the target supported FC-NVME.

Corrected by making the assumption that the target always supports
FC-NVME thus a PRLI is sent. It's ok for the target to reject it.

Subject: scsi: lpfc: Correct issues with FAWWN and FDISCs

When using fabric-assigned WWNs, the switch doesn't like copy of the
FLOGI payload, which includes valid VVL bits, to be used as the FDISC
payload.

Rather than wait for corrected switch firmware, ensure the VVL bits are
marked invalid on FDISCs.

Various oops being seen on being in the ISR too long and cpu lockups,
when under heavy load.

The amount of work being posted off of completion queues kept the ISR
running almost all the time

Correct the issue by limiting the amount of work per iteration.

Subject: scsi: lpfc: Fix MRQ > 1 context list handling

Various oops including cpu LOCKUPs were seen.

For asynchronously received ius where the driver must assign exchange
resources, the resources were on a single get (free) list and put list
(finished, waiting to be put on get list). As all cpus are sharing the
lists, an interrupt for a receive frame may have to wait for all the
other cpus to place their done work onto the put list before it can
acquire the lock to pull from the list.

Fix by breaking the resource lists into per-cpu lists or at least more
than 1 list with cpu's sharing the lists). A cpu would allocate from the
free list for its own cpu, and put its done work on the its own put list
- avoiding the contention. As cpu load may vary, when empty, a cpu may
grab from another cpu, thereby changing resource distribution.  But
searching for a resource only occurs on 1 or a few cpus until a single
resource can be allocated. if the condition reoccurs, it starts looking
at a different cpu.

Subject: scsi: lpfc: Fix relative offset error on large nvmet target ios

If the nvmet_fc transport breaks an io into multiple sequences, the
driver will improperly set the relative offset on the 2nd through N
sequences.

Correct by properly formatting the hw cmd so the relative offset is
picked up from the hw cmd.

Subject: scsi: lpfc: Fix nvme target failure after 2nd adapter reset

The nonrecovery occurred because the lpfc nvme initiator function did
not reestablish its localport creation with the nvme host transport in
lpfc_oneline.  Because of that, an NVME rport binding could not take
place.

Corrected by recreating the localport in the adapter reset recovery
routine.

Subject: scsi: lpfc: Fix bad sgl reposting after 2nd adapter reset

Port issue was fixed, the hbacmd reset would take more than 8 minutes to
complete.

There were conflicting NVME SGL posting/reposting responsibilities
between lpfc_online()/lpfc_sli4_hba_setup() and
lpfc_nvme_create_localport().  The lpfc_online() causes a REPOST on
existing NVME SGLs which is not released during the fc port reset.
However, lpfc_nvme_create_localport() wants to allocate new NVME buffers
and post them. Both cancelled out each other which had a side effect of
hosing the mailbox handling that was used to remove the sgl lists -
causing multiple 60s mbx timeouts.

Fix by preserving all SGL lists over the fc port reset.

Subject: drm/exynos/decon5433: refactor irq requesting code

To allow runtime validation of mode of work irq request
code should be split into two separate phases:
- irq reqesting,
- irq checking.
Following patches will move 2nd phase to mode validation phase.

Subject: drm/exynos: add mode_valid callback to exynos_drm

crtc::mode_valid callback is required to implement proper pipeline
validation for command/video modes. Since Exynos uses private
framework such callback should be added to it.

Subject: drm/exynos/decon5433: use mode info stored in CRTC to detect i80 mode

Since panel's mode of work is propagated properly from panel to DECON,
there is no need to use redundant private device tree property.
The only issue with such approach is that check for required interrupts
should be postponed until panel communicate its requirements, ie to
mode validation phase - mode_valid callback.

Subject: drm/exynos: mixer: fix chroma comment in vp_video_buffer()

The current comment sounds like the division op is done to
compensate for some hardware erratum. But the chroma plane
having half the height of the luma plane is just the way
NV12/NV21 is defined, so clarify this behaviour.

Subject: drm/exynos: mixer: enable NV12MT support for the video plane

The video processor supports a tiled version of the NV12 format,
known as NV12MT in V4L2 terms. The support was removed in commit
083500baefd5f4c215a5a93aef2492c1aa775828 due to not being a real
pixel format, but rather NV12 with a special memory layout.

With the introduction of FB modifiers, we can now properly support
this format again.

Tested with a hacked up modetest from libdrm's test suite on
an ODROID-X2 (Exynos4412).

Subject: drm/exynos: mixer: simplify vp_video_buffer()

DRM core already checks in drm_atomic_plane_check() if the
pixelformat is valid. Hence we can drop the default case of
the switch statement and collapse most of the code.

Also rename the two booleans to reflect what true/false
actually means, and to avoid mixing CrCb/NV21 descriptions.

No functional change.

Subject: drm/exynos: mixer: simplify mixer_graph_buffer()

DRM core already checks in drm_atomic_plane_check() if the
pixelformat is valid. Hence we can collapse the default case
of the switch statement with the XRGB8888 case.

No functional change.

Subject: drm/exynos: mixer: remove src offset from mixer_graph_buffer()

We always translate the dma address such that the offsets of
the source image are zero. Hence we can remove manipulation of
the MXR_GRAPHIC_SXY(win) register and just zero them once
in mixer_win_reset().

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The debugfs entries must be removed before an error is returned in the
probe function. Otherwise another try to load the module fails and when
the debugfs files are accessed without the module loaded, the kernel
still tries to call a function in that module.

Subject: mtd: nand: atmel: Relax tADL_min constraint

Version 4 of the ONFI spec mandates that tADL be at least 400 nanoseconds,
but, depending on the master clock rate, 400 ns may not fit in the tADL
field of the SMC reg. We need to relax the check and accept the -ERANGE
return code.

Note that previous versions of the ONFI spec had a lower tADL_min (100 or
200 ns). It's not clear why this timing constraint got increased but it
seems most NANDs are fine with values lower than 400ns, so we should be
safe.

A recent commit (272725c7db4da1fd3229d944fc76d2e98e3a144e) has removed
the use of 'bits_per_pixel' in DRM. However the corresponding Exynos
driver code still uses the ambiguous 'bpp', even though it is now
initialized from fb->cpp[0].

Consistenly use 'cpp' in FIMD, DECON7 and DECON5433 drivers.

Subject: dmaengine: k3dma: fix non-cyclic mode

Commit 36387a2b1f62b5c087c5fe6f0f7b23b94f722ad7 ("k3dma: Fix
memory handling in preparation for cyclic mode") broke the
logic around ds_run/ds_done in case of non-cyclic DMA.

This went unnoticed as the only user of k3dma was the i2s
audio driver but, with a patch set to enable dma on SPI, the
issue popped out.

The fix re-applies the initialization to ds_run/ds_done in
k3_dma_start_txd() that were removed by the commit above.

Also, one of the calls to k3_dma_start_txd() is triggered by
(ds_done != NULL), so remove the noisy and useless call to
WARN_ON_ONCE().

Subject: dmaengine: k3dma: fix double free of descriptor

Commit 36387a2b1f62b5c087c5fe6f0f7b23b94f722ad7 ("k3dma: Fix
memory handling in preparation for cyclic mode") adds code
to free the descriptor in ds_done.

In cyclic mode, ds_done is never used and it's always NULL,
so the added code is not executed.

In non-cyclic mode, ds_done is used as a flag: when not NULL
it signals that the descriptor has been consumed. No need to
free it because it would be free by vchan_complete().

The fix takes back the code changed by the commit above:
- remove the free on the descriptor;
- initialize ds_done to NULL for the next run.

Subject: dmaengine: k3dma: remove useless ON_WARN_ONCE()

Commit 36387a2b1f62b5c087c5fe6f0f7b23b94f722ad7 ("k3dma: Fix
memory handling in preparation for cyclic mode") adds few
calls to ON_WARN_ONCE() to track the use of ds_run/ds_done.

After the two fixes:
- dmaengine: k3dma: fix non-cyclic mode
- dmaengine: k3dma: fix re-free of the same descriptor
the behaviour of ds_run/ds_done is properly fixed.
The remaining ON_WARN_ONCE() are never triggered and can be
removed.

Subject: dmaengine: rcar-dmac: initialize all data before registering IRQ
 handler

Anton Volkov noticed that engine->dev is NULL before
of_dma_controller_register() in probe.
Thus there might be a NULL pointer dereference in
rcar_dmac_chan_start_xfer while accessing chan->chan.device->dev which
is equal to (&dmac->engine)->dev.
On same reason, same and similar things will happen if we didn't
initialize all necessary data before calling register irq function.
To be more safety code, this patch initialize all necessary data
before calling register irq function.

Subject: intel_th: Make SOURCE devices children of the root device

The switch (GTH) does not directly interact with SOURCE type devices and
may not even be present (in host mode). To reflect this and avoid
inconsistencies between target and host mode, make SOURCE devices
descendant directly from the root (i.e. PCI) device. Their symlinks
will no longer appear under the switch device, but they can still
be found under intel_th bus.

allow the switch to allocate only the ones that it knows about.

Subject: intel_th: Enumerate Low Power Path output port type

Trace Hub 2.x adds Low Power Path (LPP) output port type, which provides
a low power mode trace path from sources to PTI or BSSB.

This adds an output subdevice for the LPP port.

Subject: intel_th: pti: Support Low Power Path output port type

The Low Power Path (LPP) output port type, looks mostly like PTI to
the software, with a few additional bits in the control register.

This extends the PTI driver to support LPP ports as well.

Subject: intel_th: Perform time resync on capture start

On some devices (TH 2.x devices at the moment), the internal time counter
is initially not synchronized to the global crystal clock, so the time
stamps it produces will not be useful. In this case, the driver needs
to force the time counter resync.

This applies the workaround to relevant devices.

reinitialize the bios.

Subject: md: notify about new spare disk in the container

In case of external metadata arrays spare disks are added to containers
first. mdadm keeps monitoring /proc/mdstat output and when spare disk is
available, it moves it from the container to the array. The problem is
there is no notification of new spare disk in the container and mdadm
waits a long time (until timeout) before it takes the action.

Subject: md: replace seq_release_private with seq_release

Since commit f15146380d28 ("fs: seq_file - add event counter to simplify
poll() support"), md.c code has been no longer used the private field of
the struct seq_file, but seq_release_private() has been continued to be
used to release the allocated seq_file. This seems to have been
forgotten. So convert it to use seq_release() instead of
seq_release_private().

Now raid5_build_block is just called to set the
sector of r5dev, raid5_compute_blocknr can be
used directly for the purpose.

Subject: virtio_blk: fix incorrect message when disk is resized

The message printed on disk resize is incorrect.  The following is
printed when resizing to 2 GiB:

  $ truncate -s 1G test.img
  $ qemu -device virtio-blk-pci,logical_block_size=4096,...
  (qemu) block_resize drive1 2G

  virtio_blk virtio0: new size: 4194304 4096-byte logical blocks (17.2 GB/16.0 GiB)

The virtio_blk capacity config field is in 512-byte sector units
regardless of logical_block_size as per the VIRTIO specification.
Therefore the message should read:

  virtio_blk virtio0: new size: 524288 4096-byte logical blocks (2.15 GB/2.0 GiB)

Note that this only affects the printed message.  Thankfully the actual
block device has the correct size because the block layer expects
capacity in sectors.

Subject: virtio_pci: fix cpu affinity support

Commit 0b0f9dc5 ("Revert "virtio_pci: use shared interrupts for
virtqueues"") removed the adjustment of the pre_vectors for the virtio
MSI-X vector allocation which was added in commit fb5e31d9 ("virtio:
allow drivers to request IRQ affinity when creating VQs"). This will
lead to an incorrect assignment of MSI-X vectors, and potential
deadlocks when offlining cpus.

Subject: xen-blkback: stop blkback thread of every queue in
 xen_blkif_disconnect
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In xen_blkif_disconnect, before checking inflight I/O, following code
stops the blkback thread,
if (ring->xenblkd) {
	kthread_stop(ring->xenblkd);
	wake_up(&ring->shutdown_wq);
}
If there is inflight I/O in any non-last queue, blkback returns -EBUSY
directly, and above code would not be called to stop thread of remaining
queue and processs them. When removing vbd device with lots of disk I/O
load, some queues with inflight I/O still have blkback thread running even
though the corresponding vbd device or guest is gone.
And this could cause some problems, for example, if the backend device type
is file, some loop devices and blkback thread always lingers there forever
after guest is destroyed, and this causes failure of umounting repositories
unless rebooting the dom0.
This patch allows thread of every queue has the chance to get stopped.
Otherwise, only thread of queue previous to(including) first busy one get
stopped, blkthread of remaining queue will still run.  So stop all threads
properly and return -EBUSY if any queue has inflight I/O.

Subject: scsi: Suppress gcc 7 fall-through warnings reported with W=1

The conclusion of a recent discussion about the new warnings
reported by gcc 7 is that the new warnings reported when building
with W=1 should be suppressed. However, gcc 7 still warns about
fall-through in switch statements when building with W=1. Suppress
these warnings by annotating the SCSI core properly.

See also Linus Torvalds, Lots of new warnings with gcc-7.1.1, 11
July 2017 (https://www.mail-archive.com/linux-media@vger.kernel.org/msg115428.html).

Subject: scsi: Use blk_mq_rq_to_pdu() to convert a request to a SCSI command
 pointer

Since commit e9c787e65c0c ("scsi: allocate scsi_cmnd structures as
part of struct request") struct request and struct scsi_cmnd are
adjacent. This means that there is now an alternative to reading
req->special to convert a pointer to a prepared request into a
SCSI command pointer, namely by using blk_mq_rq_to_pdu(). Make
this change where appropriate. Although this patch does not
change any functionality, it slightly improves performance and
slightly improves readability.

Subject: scsi: sd: sr: Convert two assignments into warning statements

Before scsi_prep_fn() calls the ULP .init_command() callback
function it stores the SCSI command pointer in request.special.
This means that the SCpnt = rq->special assignments in the sd
and sr drivers assign a pointer to itself. Hence convert these
two assignment statements into warning statements.

Subject: scsi: bfa: move bus reset to target reset

The bus reset handler is just calling target reset on all targets, which
is exactly what SCSI EH will be doing anyway.  So move the bus reset
function to target reset and drop the loop.

Subject: scsi: aha152x: drop host reset

The driver has both a bus and a host reset, where the host reset does a
bus reset followed by an attempt to reset the chip registers to a
default state.  However, as the bus reset always returned SUCCESS the
host reset was never called, so the functionality of the register reset
function was never validated.  Additionally, tha AIC-6260 chip has a
hard reset line, which actually should be preferred for a host
reset. But I haven't found a way how this can be triggered via software,
so take the safe approach and drop the host reset.

Subject: scsi: 53c700: move bus reset to host reset

bus reset always returns SUCCESS, meaning host reset was never
tested. At the same time the only difference to the HBA is a missing
call to NCR_700_chip_reset().  So add the missing call to bus reset,
drop host reset, and move bus reset to host reset.

Subject: skd: Remove SKD_ID_INCR

The SKD_ID_INCR flag in skd_request_context.id duplicates information
that is already available otherwise, e.g. through the block layer
request state and through skd_request_context.state. Hence remove
the code that manipulates this flag and also the flag itself.
Since skd_isr_completion_posted() only uses the lower bits of
skd_request_context.id as hardware tag, this patch does not change
the behavior of the skd driver. I'm referring to the following code:

    tag = req_id & SKD_ID_SLOT_AND_TABLE_MASK;

Subject: scsi: mptsas: Fixup device hotplug for VMWare ESXi

VMWare ESXi emulates an mptsas HBA, but exposes all drives as
direct-attached SAS drives.  This it not how the driver originally
envisioned things; SAS drives were supposed to be connected via an
expander, and only SATA drives would be direct attached.  As such, any
hotplug event for direct-attach SAS drives was silently ignored, and the
guest failed to detect new drives from within a VMWare ESXi environment.

[mkp: typos]

Subject: scsi: ses: Fix racy cleanup of /sys in remove_dev()

Currently we free the resources backing the enclosure device before we
call device_unregister(). This is racy: during rmmod of low-level SCSI
drivers that hook into enclosure, we end up with a small window of time
during which writing to /sys can OOPS. Example trace with mpt3sas:

  general protection fault: 0000 [#1] SMP KASAN
  Modules linked in: mpt3sas(-) <...>
  RIP: [<ffffffffa0388a98>] ses_get_page2_descriptor.isra.6+0x38/0x220 [ses]
  Call Trace:
   [<ffffffffa0389d14>] ses_set_fault+0xf4/0x400 [ses]
   [<ffffffffa0361069>] set_component_fault+0xa9/0xf0 [enclosure]
   [<ffffffff8205bffc>] dev_attr_store+0x3c/0x70

   [<ffffffff828b401b>] entry_SYSCALL_64_fastpath+0x13/0x94

Fortunately the solution is extremely simple: call device_unregister()
before we free the resources, and the race no longer exists. The driver
core holds a reference over ->remove_dev(), so AFAICT this is safe.

Subject: i40evf: prevent VF close returning before state transitions to DOWN

Currently i40evf_close() can return before state transitions to
__I40EVF_DOWN because of the latency involved in processing and
receiving response from PF driver and scheduling of VF watchdog_task.
Due to this inconsistency an immediate call to i40evf_open() fails
because state is still DOWN_PENDING.

When a VF interface is in up state and we try to add it as slave,
The bonding driver calls dev_close() and dev_open() in short duration
resulting in dev_open returning error. The ifenslave command needs
to be run again for dev_open to succeed.

This fix ensures that watchdog timer is scheduled immediately after
admin queue operations are scheduled in i40evf_down(). In addition a
wait condition is added at the end of i40evf_close so that function
wont return when state is still DOWN_PENDING. The timeout value is
chosen after some profiling and includes some buffer.

Subject: i40e: Fix a bug with VMDq RSS queue allocation

The X722 pf flag setup should happen before the VMDq RSS queue count is
initialized for VMDq VSI to get the right number of queues for RSS in
case of X722 devices.

Subject: i40e: separate hw_features from runtime changing flags

The number of flags found in pf->flags has grown quite large, and there
are a lot of different types of flags. Most of the flags are simply
hardware features which are enabled on some firmware or some MAC types.
Other flags are dynamic run-time flags which enable or disable certain
features of the driver.

Separate these two types of flags into pf->hw_features and pf->flags.
The hw_features list will contain a set of features which are enabled at
init time. This will not contain toggles or otherwise dynamically
changing features. These flags should not need atomic protections, as
they will be set once during init and then be essentially read only.

Everything else will remain in the flags variable. These flags may be
modified at any time during run time. A future patch may wish to convert
these flags into set_bit/clear_bit/test_bit or similar approach to
ensure atomic correctness.

The I40E_FLAG_MFP_ENABLED flag may be a good fit for hw_features but
currently is used by ethtool in the private flags settings, and thus has
been left as part of flags.

Additionally, I40E_FLAG_DCB_CAPABLE may be a good fit for the
hw_features but this patch has not tried to untangle it yet.

Subject: i40e: remove workaround for Open Firmware MAC address

Since commit b499ffb0a22c ("i40e: Look up MAC address in Open Firmware
or IDPROM"), we've had support for obtaining the MAC address
form Open Firmware or IDPROM.

This code relied on sending the Open Firmware address directly to the
device firmware instead of relying on our MAC/VLAN filter list. Thus,
a work around was introduced in commit b1b15df59232 ("i40e: Explicitly
write platform-specific mac address after PF reset")

We refactored the Open Firmware address enablement code in the ill-named
commit 41c4c2b50d52 ("i40e: allow look-up of MAC address from Open
Firmware or IDPROM")

Since this refactor, we no longer even set I40E_FLAG_PF_MAC. Further, we
don't need this work around, because we actually store the MAC address
as part of the MAC/VLAN filter hash. Thus, we will restore the address
correctly upon reset.

The refactor above failed to revert the workaround, so do that now.

Subject: i40e: Detect ATR HW Evict NVM issue and disable the feature

This patch fixes a problem with the HW ATR eviction feature where the
NVM setting was incorrect.  This patch detects the issue on X720
adapters and disables the feature if the NVM setting is incorrect.

Without this patch, HW ATR Evict feature does not work on broken NVMs
and is not detected either.  If the HW ATR Evict feature is disabled
the SW Eviction feature will take effect.

Subject: i40e/i40evf: use cmpxchg64 when updating private flags in ethtool

When a user gives an invalid command to change a private flag which is
not supported, either because it is read-only, or the device is not
capable of the feature, we simply ignore the request.

A naive solution would simply be to report error codes when one of the
flags was not supported. However, this causes problems because it makes
the operation not atomic. If a user requests multiple private flags
together at once we could end up changing one before failing at the
second flag.

We can do a bit better if we instead update a temporary copy of the
flags variable in the loop, and then copy it into place after. If we
aren't careful this has the pitfall of potentially silently overwriting
any changes caused by other threads.

Avoid this by using cmpxchg64 which will compare and swap the flags
variable only if it currently matched the old value. We'll report
-EAGAIN in the (hopefully rare!) case where the cmpxchg64 fails.

This ensures that we can properly report when flags are not supported in
an atomic fashion without the risk of overwriting other threads changes.

Subject: i40e: move check for avoiding VID=0 filters into i40e_vsi_add_vlan

In i40e_vsi_add_vlan we treat attempting to add VID=0 as an error,
because it does not do what the caller might expect. We already special
case VID=0 in i40e_vlan_rx_add_vid so that we avoid this error when
adding the VLAN.

This special casing is necessary so that we do not add the VLAN=0 filter
since we don't want to stop receiving untagged traffic. Unfortunately,
not all callers of i40e_vsi_add_vlan are aware of this, including when
we add VLANs from a VF device.

Rather than special casing every single caller of i40e_vsi_add_vlan,
lets just move this check internally. This makes the code simpler
because the caller does not need to be aware of how VLAN=0 is special,
and we don't forget to add this check in new places.

This fixes a harmless error message displaying when adding a VLAN from
within a VF. The message was meaningless but there is no reason to
confuse end users and system administrators, and this is now avoided.

Subject: i40e: use cpumask_copy instead of direct assignment

According to the header file cpumask.h, we shouldn't be directly copying
a cpumask_t, since its a bitmap and might not be copied correctly. Lets
use the provided cpumask_copy() function instead.

Subject: i40e: prevent changing ITR if adaptive-rx/tx enabled

Currently the driver allows the user to change (or even disable)
interrupt moderation if adaptive-rx/tx is enabled when this should
not be the case.

Adaptive RX/TX will not respect the user's ITR settings so
allowing the user to change it is weird.  This bug would also
allow the user to disable interrupt moderation with adaptive-rx/tx
enabled which doesn't make much sense either.

This patch makes it such that if adaptive-rx/tx is enabled, the user
cannot make any manual adjustments to interrupt moderation.  It also
makes it so that if ITR is disabled but adaptive-rx/tx is then
enabled, ITR will be re-enabled.

Subject: i40e: synchronize nvmupdate command and adminq subtask

During NVM update, state machine gets into unrecoverable state because
i40e_clean_adminq_subtask can get scheduled after the admin queue
command but before other state variables are updated. This causes
incorrect input to i40e_nvmupd_check_wait_event and state transitions
don't happen.

This issue existed before but surfaced after commit 373149fc99a0
("i40e: Decrease the scope of rtnl lock")

This fix adds locking around admin queue command and update of
state variables so that adminq_subtask will have accurate information
whenever it gets scheduled.

Subject: scsi: cxlflash: Avoid double mutex unlock

The AFU recovery routine uses an interruptible mutex to control the flow
of in-flight recoveries. Upon receiving an interruptible signal the code
branches to a common exit path which wrongly assumes the mutex is
held. Add a local variable to track when the mutex should be unlocked.

Subject: scsi: cxlflash: Fix vlun resize failure in the shrink path

The ioctl DK_CAPI_VLUN_RESIZE can fail if the allocated vlun size is
reduced from almost maximum capacity and then increased again.

The shrink_lxt() routine is currently using the SISL_ASTATUS_MASK to
mask the higher 48 bits of the lxt entry. This is unnecessary and
incorrect as it uses a mask designed for the asynchronous interrupt
status register.  When the 4 port support was added to cxlflash, the
SISL_ASTATUS_MASK was updated to reflect the status bits for all 4
ports. This change indirectly affected the shrink_lxt() code path.

To extract the base, simply shift the bits without masking.

Subject: scsi: lpfc: avoid false-positive gcc-8 warning

This is an interesting regression with gcc-8, showing a harmless warning
for correct code:

In file included from include/linux/kernel.h:13:0,
                 ...
                 from drivers/scsi/lpfc/lpfc_debugfs.c:23:
include/linux/printk.h:301:2: error: 'eq' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__)
  ^~~~~~
In file included from drivers/scsi/lpfc/lpfc_debugfs.c:58:0:
drivers/scsi/lpfc/lpfc_debugfs.h:451:31: note: 'eq' was declared here

I managed to reduce the warning into a small test case for gcc-8 that I
reported in the gcc bugzilla[1].

As a workaround, this changes the logic to move the two assignments of
'eq' out of the conditions and instead make the index conditional.  This
works for all configurations I tried and avoids adding a bogus
initialization.

irq_create_affinity_masks() can return NULL on non-SMP systems, when there
are not enough "free" vectors available to spread, or if memory allocation
for the CPU masks fails.  Only the allocation failure is of interest, and
even then the system will work just fine except for non-optimally spread
vectors.  Thus remove the warnings.

Subject: efi/libstub: Enable reset attack mitigation

If a machine is reset while secrets are present in RAM, it may be
possible for code executed after the reboot to extract those secrets
from untouched memory. The Trusted Computing Group specified a mechanism
for requesting that the firmware clear all RAM on reset before booting
another OS. This is done by setting the MemoryOverwriteRequestControl
variable at startup. If userspace can ensure that all secrets are
removed as part of a controlled shutdown, it can reset this variable to
0 before triggering a hardware reboot.

The crng code requires at least 64 bytes (2 * CHACHA20_BLOCK_SIZE)
to complete the fast boot-time init, so provide that many bytes
when invoking UEFI protocols to seed the entropy pool. Also, add
a notice so we can tell from the boot log when the seeding actually
took place.

Cleans up sparse warning:

Add i2c compatible for MT7622. Compare to MT8173 i2c controller,
MT7622 limits message numbers to 255, and does not support 4GB
DMA mode.

Subject: i2c: davinci: Preserve return value of devm_clk_get

The i2c driver can run into driver dependency issues if its loaded
before a clock driver it depends on. Therefore, EPROBE_DEFER may be
returned by devm_clk_get and should be returned in probe to allow the
kernel to reprobe the driver at a later time. This patch allows the error
value returned by devm_clk_get to be passed through and not overwritten.

There seems to be no need for separate ones since all users include both
files anyhow. Merge them because include/linux/i2c is to be deprecated.

Subject: i40e: Update state variable for adminq subtask

During NVM update, state machine gets into unrecoverable state because
i40e_clean_adminq_subtask can get scheduled after the admin queue
command but before other state variables are updated. This causes
incorrect input to i40e_nvmupd_check_wait_event and state transitions
don't happen.

This fix updates the state variables so that adminq_subtask will have
accurate information whenever it gets scheduled.

Subject: i40e: prevent snprintf format specifier truncation

Increase the size of the prefix buffer so that it can hold enough
characters for every possible input. Although 20 is enough for all
expected inputs, it is possible for the values to be larger than
expected, resulting in a possibly truncated string. Additionally, lets
use sizeof(prefix) in order to ensure we use the correct size if we need
to change the array length in the future.

New versions of GCC starting at 7 now include warnings to prevent
truncation unless you handle the return code. At most 27 bytes can be
written here, so lets just increase the buffer size even if for all
expected hw->bus.* values we only needed 20.

Albeit, we usually set true promiscuous mode for both multicast and
unicast at the same time - however, it is possible to set it
individually, so using allmulti flag which is only for allmulticast might
caused unwanted behavior in mirroring egress traffic promiscuous for
unicast in VF.

Subject: i40evf: fix possible snprintf truncation of q_vector->name

The q_vector names are based on the interface name with a driver prefix,
the type of q_vector setup, and the queue number. We previously set the
size of this variable to IFNAMSIZ + 9, which is incorrect, because we
actually include a minimum of 14 characters extra beyond the interface
name size.

New versions of GCC since 7 include a new warning that detects this
possible truncation and complains. We can fix this by increasing the
size in case our interface name is too large to avoid truncation. We
don't need to go beyond 14 because the compiler is smart enough to
realize our values can never exceed size of 1. We do go up to 15 here
because possible future changes may increase the number of queues beyond
one digit.

While we are here, also change some variables to be unsigned (since they
are never negative) and stop using an extra unnecessary %s format
specifier.

Subject: i40e: force VMDQ device name truncation

In new versions of GCC since 7.x a new warning exists which warns when
a string is truncated before all of the format can be completed.

When we setup VMDQ netdev names we are copying a pre-existing interface
name which could be up to 15 characters in length. Since we also add
4 bytes, v, the literal %, the d and a \0 null, we would overrun the
available size unless snprintf truncated for us.

The snprintf call will of course truncate on the end, so lets instead
modify the code to force truncation of the copied netdev name by
4 characters, to create enough space for the 4 bytes we're adding.

Subject: i40e: remove workaround for resetting XPS

Since commit 3ffa037d7f78 ("i40e: Set XPS bit mask to zero in DCB mode")
we've tried to reset the XPS settings by building a custom
empty CPU mask.

This workaround is not necessary because we're not really removing the
XPS setting, but simply setting it so that no CPU is valid.

Second, we shorten the code further by using zalloc_cpumask_var instead
of a separate call to bitmap_zero().

Subject: i40e: initialize our affinity_mask based on cpu_possible_mask

On older kernels a call to irq_set_affinity_hint does not guarantee that
the IRQ affinity will be set. If nothing else on the system sets the IRQ
affinity this can result in a bug in the i40e_napi_poll() routine where
we notice that our interrupt fired on the "wrong" CPU according to our
internal affinity_mask variable.

This results in a bug where we continuously tell NAPI to stop polling to
move the interrupt to a new CPU, but the CPU never changes because our
affinity mask does not match the actual mask setup for the IRQ.

The root problem is a mismatched affinity mask value. So lets initialize
the value to cpu_possible_mask instead. This ensures that prior to the
first time we get an IRQ affinity notification we'll have the mask set
to include every possible CPU.

We use cpu_possible_mask instead of cpu_online_mask since the former is
almost certainly never going to change, while the later might change
after we've made a copy.

Subject: i40e: invert logic for checking incorrect cpu vs irq affinity

In commit 96db776a3682 ("i40e/vf: fix interrupt affinity bug")
we added some code to force exit of polling in case we did
not have the correct CPU. This is important since it was possible for
the IRQ affinity to be changed while the CPU is pegged at 100%. This can
result in the polling routine being stuck on the wrong CPU until
traffic finally stops.

Unfortunately, the implementation, "if the CPU is correct, exit as
normal, otherwise, fall-through to the end-polling exit" is incredibly
confusing to reason about. In this case, the normal flow looks like the
exception, while the exception actually occurs far away from the if
statement and comment.

We recently discovered and fixed a bug in this code because we were
incorrectly initializing the affinity mask.

Re-write the code so that the exceptional case is handled at the check,
rather than having the logic be spread through the regular exit flow.
This does end up with minor code duplication, but the resulting code is
much easier to reason about.

The new logic is identical, but inverted. If we are running on a CPU not
in our affinity mask, we'll exit polling. However, the code flow is much
easier to understand.

Note that we don't actually have to check for MSI-X, because in the MSI
case we'll only have one q_vector, but its default affinity mask should
be correct as it includes all CPUs when it's initialized. Further, we
could at some point add code to setup the notifier for the non-MSI-X
case and enable this workaround for that case too, if desired, though
there isn't much gain since its unlikely to be the common case.

Subject: i40e/i40evf: remove ULTRA latency mode

Since commit c56625d59726 ("i40e/i40evf: change dynamic interrupt
thresholds") a new higher latency ITR setting called I40E_ULTRA_LATENCY
was added with a cryptic comment about how it was meant for adjusting Rx
more aggressively when streaming small packets.

This mode was attempting to calculate packets per second and then kick
in when we have a huge number of small packets.

Unfortunately, the ULTRA setting was kicking in for workloads it wasn't
intended for including single-thread UDP_STREAM workloads.

This wasn't caught for a variety of reasons. First, the ip_defrag
routines were improved somewhat which makes the UDP_STREAM test still
reasonable at 10GbE, even when dropped down to 8k interrupts a second.
Additionally, some other obvious workloads appear to work fine, such
as TCP_STREAM.

The number 40k doesn't make sense for a number of reasons. First, we
absolutely can do more than 40k packets per second. Second, we calculate
the value inline in an integer, which sometimes can overflow resulting
in using incorrect values.

If we fix this overflow it makes it even more likely that we'll enter
ULTRA mode which is the opposite of what we want.

The ULTRA mode was added originally as a way to reduce CPU utilization
during a small packet workload where we weren't keeping up anyways. It
should never have been kicking in during these other workloads.

Given the issues outlined above, let's remove the ULTRA latency mode. If
necessary, a better solution to the CPU utilization issue for small
packet workloads will be added in a future patch.

Subject: i40e/i40evf: avoid dynamic ITR updates when polling or low packet
 rate

The dynamic ITR algorithm depends on a calculation of usecs which
assumes that the interrupts have been firing constantly at the interrupt
throttle rate. This is not guaranteed because we could have a low packet
rate, or have been polling in software.

We'll estimate whether this is the case by using jiffies to determine if
we've been too long. If the time difference of jiffies is larger we are
guaranteed to have an incorrect calculation. If the time difference of
jiffies is smaller we might have been polling some but the difference
shouldn't affect the calculation too much.

This ensures that we don't get stuck in BULK latency during certain rare
situations where we receive bursts of packets that force us into NAPI
polling.

Subject: PM / devfreq: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: PM / devfreq: Move private devfreq_update_stats() into devfreq

THe devfreq_update_stats() updates the 'struct devfreq_dev_status'
in order to get current status of devfreq device. It is only used
for the governors.

This patch moves the devfreq_update_stats() into devfreq directory.

Subject: PM / devfreq: Fix memory leak when fail to register device

When the devfreq_add_device fails to register deivce, the memory
leak of devfreq instance happen. So, this patch fix the memory
leak issue. Before freeing the devfreq instance checks whether
devfreq instance is NULL or not because the device_unregister()
frees the devfreq instance when jumping to the 'err_init'.
It is to prevent the duplicate the kfee(devfreq).

Subject: staging: rtlwifi: check for array overflow

Smatch is distrustful of the "capab" value and marks it as user
controlled.  I think it actually comes from the firmware?  Anyway, I
looked at other drivers and they added a bounds check and it seems like
a harmless thing to have so I have added it here as well.

Subject: staging: rtlwifi: Improve debugging by using debugfs

The changes in this commit are also being sent to the main rtlwifi
drivers in wireless-next; however, these changes will also be useful for
any debugging of r8822be before it gets moved into the main tree.

Use debugfs to dump register and btcoex status, and also write registers
and h2c.

We create topdir in /sys/kernel/debug/rtlwifi/, and use the MAC address
as subdirectory with several entries to dump mac_reg, bb_reg, rf_reg etc.
An example is
    /sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/mac_0

This change permits examination of device registers in a dynamic manner,
a feature not available with the current debug mechanism.

We use seq_file to replace RT_TRACE to dump status, then we can use 'cat'
to access btcoex's status through debugfs.
(i.e. /sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/btcoex)
Other related changes are
1. implement btc_disp_dbg_msg() to access btcoex's common status.
2. remove obsolete field bt_exist

We recently changed from using obd_ioctl_popdata() to calling
copy_to_user() directly.  This if statement was supposed to be deleted
but it was over looked.  "err" is zero at this point so it means we
return success.

The call to _rtl_dbg_trace via macro HALMAC_RT_TRACE will trigger a null
pointer deference on the null driver_adapter.  Fix this by assigning
driver_adapter earlier to halmac_adapter->driver_adapter before the tracing
call so that a non-null driver_adapter is passed instead.

Remove "struct pt_regs *" parameter from interrupt handlers, since
it is no longer passed to interrupt handlers. Also, convert return
types to irqreturn_t.

Additionally, move DIO_irq_handler variable into the setup_GPIO
function, as it's not used outside of this function.

There are multiple places in usb core or controller driver which returns
-EMSGSIZE when a class driver queueing urb failed, so the "Message too
long" log doesn't help much for understanding the error.

Let the musb driver to specifically print a error message when
musb_urb_enqueue() returns -EMSGSIZE.

Subject: USB: musb: fix external abort on suspend

Make sure that the controller is runtime resumed when system suspending
to avoid an external abort when accessing the interrupt registers:

  Unhandled fault: external abort on non-linefetch (0x1008) at 0xd025840a
  ...
  [<c05481a4>] (musb_default_readb) from [<c0545abc>] (musb_disable_interrupts+0x84/0xa8)
  [<c0545abc>] (musb_disable_interrupts) from [<c0546b08>] (musb_suspend+0x38/0xb8)
  [<c0546b08>] (musb_suspend) from [<c04a57f8>] (platform_pm_suspend+0x3c/0x64)

This is easily reproduced on a BBB by enabling the peripheral port only
(as the host port may enable the shared clock) and keeping it
disconnected so that the controller is runtime suspended. (Well, you
would also need to the not-yet-merged am33xx-suspend patches by Dave
Gerlach to be able to suspend the BBB.)

This is a regression that was introduced by commit 1c4d0b4e1806 ("usb:
musb: Remove pm_runtime_set_irq_safe") which allowed the parent glue
device to runtime suspend and thereby exposed a couple of older issues:

Register accesses without explicitly making sure the controller is
runtime resumed during suspend was first introduced by commit c338412b5ded
("usb: musb: unconditionally save and restore the context on suspend")
in 3.14.

Commit a1fc1920aaaa ("usb: musb: core: make sure musb is in RPM_ACTIVE on
resume") later started setting the RPM status to active during resume,
and this was also implicitly relying on the parent always being active.
Since commit 71723f95463d ("PM / runtime: print error when activating a
child to unactive parent") this now also results in the following
warning:

  musb-hdrc musb-hdrc.0: runtime PM trying to activate child device
    musb-hdrc.0 but parent (47401400.usb) is not active

This patch has been verified on 4.13-rc2, 4.12 and 4.9 using a BBB
(the dsps glue would always be active also in 4.8).

Fixes: c338412b5ded ("usb: musb: unconditionally save and restore the context on suspend")
Fixes: a1fc1920aaaa ("usb: musb: core: make sure musb is in RPM_ACTIVE on resume")
Fixes: 1c4d0b4e1806 ("usb: musb: Remove pm_runtime_set_irq_safe")

Subject: USB: musb: dsps: add explicit runtime resume at suspend

The musb_dsps driver is special in that the parent (glue) device's
driver is accessing registers mapped by the child. The clock is however
shared and is managed by the grandparent device.

Since commit 869c59782981 ("usb: musb: dsps: add support for suspend and
resume") the dsps driver has been accessing these registers as part of
suspend and resume.

The parent driver obviously cannot runtime resume the child during
system suspend and is currently relying on the fact that the child will
be RPM_ACTIVE throughout suspend. The suspend implementation also makes
sure to check that the child is indeed present (and hence the clock
enabled) before accessing the registers.

Let's add an explicit runtime resume of the glue device itself to enable
the clock before doing the register accesses in case these assumptions ever
change (i.e. if the child is left runtime suspended).

Note that the glue-timer cancellation is moved after the child-presence
check to keep error handling simple. This should be fine as the timer is
not setup until the controller is being registered and at that time
glue->musb and its driver data have already been initialised.

Subject: USB: core: Avoid race of async_completed() w/ usbdev_release()

While running reboot tests w/ a specific set of USB devices (and
slub_debug enabled), I found that once every few hours my device would

Investigation using kgdb() found that the wait queue that was passed
into wake_up() had been freed (it was filled with slub_debug poison).

I analyzed and instrumented the code and reproduced.  My current
belief is that this is happening:

1. async_completed() is called (from IRQ).  Moves "as" onto the
   completed list.
2. On another CPU, proc_reapurbnonblock_compat() calls
   async_getcompleted().  Blocks on spinlock.
3. async_completed() releases the lock; keeps running; gets blocked
   midway through wake_up().
4. proc_reapurbnonblock_compat() => async_getcompleted() gets the
   lock; removes "as" from completed list and frees it.
5. usbdev_release() is called.  Frees "ps".
6. async_completed() finally continues running wake_up().  ...but
   wake_up() has a pointer to the freed "ps".

The instrumentation that led me to believe this was based on adding
some trace_printk() calls in a select few functions and then using
kdb's "ftdump" at crash time.  The trace follows (NOTE: in the trace
below I cheated a little bit and added a udelay(1000) in
async_completed() after releasing the spinlock because I wanted it to
trigger quicker):

<...>-2104   0d.h2 13759034us!: async_completed at start: as=ffffffc0cc638200
mtpd-2055    3.... 13759356us : async_getcompleted before spin_lock_irqsave
mtpd-2055    3d..1 13759362us : async_getcompleted after list_del_init: as=ffffffc0cc638200

mtpd-2055    3.... 13759479us : usbdev_release at start: ps=ffffffc0cc042080
mtpd-2055    3.... 13759487us : async_getcompleted before spin_lock_irqsave
mtpd-2055    3.... 13759497us!: usbdev_release after kfree(ps): ps=ffffffc0cc042080
<...>-2104   0d.h2 13760294us : async_completed before wake_up(): as=ffffffc0cc638200

To fix this problem we can just move the wake_up() under the ps->lock.
There should be no issues there that I'm aware of.

Subject: iommu: qcom: annotate PM functions as __maybe_unused

The qcom_iommu_disable_clocks() function is only called from PM
code that is hidden in an #ifdef, causing a harmless warning without
CONFIG_PM:

drivers/iommu/qcom_iommu.c:601:13: error: 'qcom_iommu_disable_clocks' defined but not used [-Werror=unused-function]
 static void qcom_iommu_disable_clocks(struct qcom_iommu_dev *qcom_iommu)

 static int qcom_iommu_enable_clocks(struct qcom_iommu_dev *qcom_iommu)

Replacing that #ifdef with __maybe_unused annotations lets the compiler
drop the functions silently instead.

Subject: iommu/amd: Check if domain is NULL in get_domain() and return -EBUSY

In get_domain(), 'domain' could be NULL before it's passed to dma_ops_domain()
to dereference. And the current code calling get_domain() can't deal with the
returned 'domain' well if its value is NULL.

So before dma_ops_domain() calling, check if 'domain' is NULL, If yes just return
ERR_PTR(-EBUSY) directly.

Subject: iommu/amd: Rename a few flush functions

Rename a few iommu cache-flush functions that start with
iommu_ to start with amd_iommu now. This is to prevent name
collisions with generic iommu code later on.

Subject: usb: xhci: Support enabling of compliance mode for xhci 1.1

To perform SuperSpeed compliance testing the port should first
be placed into compliance mode. For xHCI 1.0 and prior this
transition happens automatically when the port is in Training
and encounters an LFPS timeout. Thus running compliance tests
against a test appliance may simply just work by simply plugging
in to the downstream port.

However starting with xHCI 1.1 the transition from Polling.LFPS
to compliance mode may be disabled by default and needs to be
explicitly enabled by writing to the PLS field of the PORTSC
register, which sets an internal 'CTE' (Compliance Transition
Enabled) flag so that the port will perform the transition the
next time it encounters LFPS timeout. Whether this is disabled or
not is determined by the 'CTC' (Compliance Transition Capability)
bit in the HCCPARAMS2 capability register.

In order to allow a test operator to change this if needed, allow
a test driver (such as drivers/usb/misc/lvstest.c) to send a
SET_FEATURE(PORT_LINK_STATE) control message to the root hub to
update the link state prior to connecting to the port. Subsequently,
placing the port in warm reset would then disable the flag.

Subject: usb: misc: lvstest: add entry to place port in compliance mode

Add support for the SuperSpeed Link Layer test case TD.7.34
which requires the operator to place the port into compliance
mode, and to subsequently bring it out via reset. Historically
according to the (now deprecated) USB 3.0 specification a
SuperSpeed host downstream port would automatically transition
to Compliance mode from the Polling state if LFPS polling times
out. However the language in USB 3.1 as well as xHCI 1.1 states
it may be required to explicitly enable this transition. For
such hosts this is done by sending a SET_FEATURE(PORT_LINK_STATE)
with the state set to Compliance to the root hub port.

Similar to the other supported commands, to do this via sysfs:

     echo  > /sys/bus/usb/devices/2-0\:1.0/enable_compliance

According to xHCI 1.1 section 4.19.1.2.4.1, this enables the
transition to compliance mode upon LFPS timeout. Note that this
can only be issued when the port is in disconnected state. And
in order to disable this behavior on subsequent transitions, a
warm reset should be issued. So add another entry to do that:

     echo  > /sys/bus/usb/devices/2-0\:1.0/warm_reset

In general these attributes can also be useful for other USB
SuperSpeed compliance tests such as electrical and eye diagram
testing which require CPn patterns to be transmitted.

Subject: usb: Add device quirk for Logitech HD Pro Webcam C920-C

Commit e0429362ab15
("usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e")
introduced quirk to workaround an issue with some Logitech webcams.

Apparently model C920-C has the same issue so applying
the same quirk as well.

See aforementioned commit message for detailed explanation of the problem.

Subject: dmaengine: bcm-sba-raid: Common flags for sba_request state and fence

This patch merges sba_request state and fence into common
sba_request flags. The sba_request flags not only saves
memory but it can also be extended in-future without adding
new members.

We also make each sba_request state as separate bit in
sba_request flags to help debugging situations where a
sba_request is accidently in two states.

Subject: dmaengine: bcm-sba-raid: Remove redundant resp_dma from sba_request

Both resp and resp_dma are redundant in sba_request because
resp is unused and resp_dma carries same information present
in tx.phys of sba_request. This patch removes both resp and
resp_dma from sba_request.

Subject: dmaengine: bcm-sba-raid: Allow arbitrary number free sba_request

Currently, we cannot have any arbitrary number of free sba_request
because sba_prealloc_channel_resources() allocates an array of
sba_request using devm_kcalloc() and kcalloc() cannot provide
memory beyond certain size.

This patch removes "reqs" (sba_request array) from sba_device
and makes "cmds" as variable array (instead of pointer) in
sba_request. This helps sba_prealloc_channel_resources() to
allocate sba_request and associated SBA command in one allocation
which in-turn allows arbitrary number of free sba_request.

Subject: dmaengine: bcm-sba-raid: Increase number of free sba_request

Currently, we have only 1024 free sba_request created
by sba_prealloc_channel_resources(). This is too low
and the prep_xxx() callbacks start failing more often
at time of RAID array setup over NVMe disks.

This patch sets number of free sba_request created by
sba_prealloc_channel_resources() to be:
<number_of_mailbox_channels> x 8192

Due to above, we will have sufficient number of free
sba_request and prep_xxx() callbacks failing is very
unlikely.

Subject: dmaengine: bcm-sba-raid: Improve sba_issue_pending() run duration

The pending sba_request list can become very long in real-life usage
(e.g. setting up RAID array) which can cause sba_issue_pending() to
run for long duration.

This patch adds common sba_process_deferred_requests() to process
few completed and pending requests so that it finishes in short
duration. We use this common sba_process_deferred_requests() in
both sba_issue_pending() and sba_receive_message().

Subject: dmaengine: bcm-sba-raid: Alloc resources before registering DMA
 device

We should allocate DMA channel resources before registering the
DMA device in sba_probe() because we can get DMA request soon
after registering the DMA device. If DMA channel resources are
not allocated before first DMA request then SBA-RAID driver will
crash.

Subject: dmaengine: bcm-sba-raid: Peek mbox when we have no free requests

When setting up RAID array on several NVMe disks we observed that
sba_alloc_request() start failing (due to no free requests left)
and RAID array setup becomes very slow.

To improve performance, we do mbox channel peek when we have
no free requests. This improves performance of RAID array setup
because mbox requests that were completed but not processed by
mbox completion worker will be processed immediately by mbox
channel peek.

Subject: dmaengine: bcm-sba-raid: Re-factor sba_process_deferred_requests()

Currently, sba_process_deferred_requests() handles both pending
and completed sba_request which is unnecessary overhead for
sba_issue_pending() because completed sba_request handling is
not required in sba_issue_pending().

This patch breaks sba_process_deferred_requests() into two parts
sba_process_received_request() and _sba_process_pending_requests().

The sba_issue_pending() will only process pending sba_request
by calling _sba_process_pending_requests(). This will improve
sba_issue_pending().

The sba_receive_message() will only process received sba_request
by calling sba_process_received_request() for each received
sba_request. The sba_process_received_request() will also call
_sba_process_pending_requests() after handling received sba_request
because we might have pending sba_request not submitted by previous
call to sba_issue_pending().

Subject: dmaengine: bcm-sba-raid: Remove redundant SBA_REQUEST_STATE_RECEIVED

The SBA_REQUEST_STATE_RECEIVED state is now redundant because
received sba_request are immediately freed or moved to completed
list in sba_process_received_request().

This patch removes redundant SBA_REQUEST_STATE_RECEIVED state.

Subject: dmaengine: bcm-sba-raid: Explicitly ACK mailbox message after sending

We should explicitly ACK mailbox message because after
sending message we can know the send status via error
attribute of brcm_message.

This will also help SBA-RAID to use "txdone_ack" method
whenever mailbox controller supports it.

Subject: dmaengine: bcm-sba-raid: Remove redundant SBA_REQUEST_STATE_COMPLETED

The SBA_REQUEST_STATE_COMPLETED state was added to keep track
of sba_request which got completed but cannot be freed because
underlying Async Tx descriptor was not ACKed by DMA client.

Instead of above, we can free the sba_request with non-ACKed
Async Tx descriptor and sba_alloc_request() will ensure that
it always allocates sba_request with ACKed Async Tx descriptor.
This alternate approach makes SBA_REQUEST_STATE_COMPLETED state
redundant hence this patch removes it.

Subject: spmi: pmic-arb: remove the read/write access checks

The access mode checks for peripheral ownership for read/write
permissions should not be required. Every peripheral enabled for
this master is expected to have a read/write permissions. If there
is any such invalid access due to wrong configuration in boot loader
or device tree files, then it should be fixed in those locations.
Hence, remove the access mode checks from the driver.

Subject: spmi: pmic-arb: rename pa_xx to pmic_arb_xx and other cleanup

This patch cleans up the following.

- Rename the "pa" to "pmic_arb".
- Rename the spmi_pmic_arb *dev to spmi_pmic_arb *pmic_arb.
- Rename the pa_{read,write}_data() functions to
  pmic_arb_{read,write}_data().
- Rename channel to APID.
- Rename the HWIRQ_*() macros to hwirq_to_*().

Subject: spmi: pmic-arb: return the value instead of passing by pointer

Returning the output value from a function, when it is possible, is the
better and cleaner way than passing it by the pointer. Hence, modify
the ppid_to_apid mapping function to return apid instead of passing
it by a pointer. While at it, pass the ppid as function parameter to
ppid_to_apid mapping function instead of passing the sid and addr.

Subject: spmi: pmic-arb: use irq_chip callback to set spmi irq wakeup
 capability

Currently the driver sets the pmic arbiter core interrupt as wakeup capable
irrespective of the child irqs which causes the system to wakeup
unnecessarily. To fix this, set the core interrupt as wakeup capable
only if any of the child irqs request for it. Do this by marking it as
wakeup capable in the irq_set_wake callback.

Subject: spmi: pmic-arb: return __iomem pointer instead of offset

Modify the pmic_arb version ops to return an __iomem pointer
to the address instead of an offset. That way we do not need to
care about the base address changes in the new HW version.

Subject: spmi: pmic-arb: fix a possible null pointer dereference

If "core" memory resource is not specified, then the driver could
end up dereferencing a null pointer. Fix this issue.

Subject: spmi: pmic-arb: add support for HW version 5

Add support for version 5 of the SPMI PMIC arbiter.  It utilizes
different offsets for registers than those found on version 3.
Also, the procedure to determine if writing and IRQ access is
allowed for a given PPID changes for version 5.

Subject: spmi: pmic-arb: Remove checking opc value not less than 0

The opc parameter in pmic_arb_write_cmd() function is defined with type
u8 and it's always greater than or equal to 0. Checking that it's not
less than 0 is redundant and it can cause a forbidden warning during
compilation. Remove the check.

Check the irq ownership in the irq_request_resources callback
instead of checking it during the irq mapping. This can prevent
installing the flow handler for the interrupt that is not owned by the EE
and allow the irq translation during the gpio driver probe.

When using the block layer in single queue mode, get_request()
returns ERR_PTR(-EAGAIN) if the queue is dying and the REQ_NOWAIT
flag has been passed to get_request(). Avoid that the kernel
reports soft lockup complaints in this case due to continuous
requeuing activity.

Subject: coresight: Correct buffer lost increment

Many conditions may cause synchronisation to be lost when updating
the perf ring buffer but the end result is still the same: synchronisation
is lost.  As such there is no need to increment the lost count for each
condition, just once will suffice.

Internal CoreSight components are rendering trace data in little-endian

Subject: coresight: Add barrier packet for synchronisation

When a buffer overflow happens the synchronisation patckets usually
present at the beginning of the buffer are lost, a situation that
prevents the decoder from knowing the context of the traces being
decoded.

This patch adds a barrier packet to be used by sink IPs when a buffer
overflow condition is detected.  These barrier packets are then used
by the decoding library as markers to force re-synchronisation.

Subject: coresight: ptm: Adds trace return stack option programming for PTM.

Adds handling to program the return stack option into PTM hardware if
specified in the perf command line.

If option is not supported by the hardware then it will be ignored.
This allows capture to move between core/ETM combinations that have the
hardware support to those that do not.

Subject: coresight replicator: Cleanup programmable replicator naming

The Linux coresight drivers define the programmable ATB replicator as
Qualcomm replicator, while this is designed by ARM. This can cause
confusion to a user selecting the driver. Cleanup all references to
make it explicitly clear. This patch :

 1) Replace the compatible string for the replicator :
      qcom,coresight-replicator1x => arm,coresight-dynamic-replicator
 2) Changes the Kconfig symbol (since this is not part of any defconfigs)
     CORESIGHT_QCOM_REPLICATOR => CORESIGHT_DYNAMIC_REPLICATOR
 3) Improves the help message in the Kconfig.
 4) Changes the name of the driver and the file :
      coresight-replicator-qcom => coresight-dynamic-replicator

Subject: coresight: Add support for reading 64bit registers

Add support for reading a lower and upper 32bits of a register
as a single 64bit register. Also add simplified macros for
direct register accesses.

Subject: coresight tmc: Handle configuration types properly

Coresight SoC 600 defines a new configuration for TMC, Embedded Trace
Streamer (ETS), indicated by 0x3 in MODE:CONFIG_TYPE. This would break
the existing driver which will treat anything other than ETR/ETB as an
ETF. Fix the driver to check the configuration type properly and also
add a warning if we encounter an unsupported configuration (ETS).

Subject: coresight tmc etr: Add capabilitiy information

With new version of TMC ETR, there are differing set of
features supported by the TMC. Add the capability of a
given TMC ETR for making safer decisions at runtime.

The device configuration register of the TMC (DEVID) lists
some of the capabilities. So, we can detect some of them at
probe. However, some of the features (or changes in behavior)
are not advertised and we have to depend on the PID to infer
the features. So we use a static description of the "unadvertised"
capabilities attached to the PID. Combining both, the static
and the dynamic capabilities, we maintain a bitmask of the
available features which can be later checked to take
appropriate actions.

The SG unit in the TMC has been removed in Coresight SoC-600.
This is however advertised by DEVID:Bit 24 = 0b1. On the
previous generation, the bit is RES0, hence we can rely on the
DEVID to detect the support.

Subject: coresight tmc etr: Detect address width at runtime

TMC in Coresight SoC-600 advertises the AXI address width
in the device configuration register.

Bit 16 - AXIAW_VALID
 0 - AXI Address Width not valid
 1 - Valid AXI Address width in Bits[23-17]

Bits [23-17] - AXIAW. If AXIAW_VALID = b01 then
 0x20 - 32bit AXI address bus
 0x28 - 40bit AXI address bus
 0x2c - 44bit AXI address bus
 0x30 - 48bit AXI address bus
 0x34 - 52bit AXI address bus

Use the address bits from the device configuration register, if
available. Otherwise, default to 40bit.

Subject: coresight tmc etr: Setup AXI cache encoding for read transfers

If the ETR supports split cache encoding (i.e, separate bits for
read and write transfers) unlike the older version (where read
and write transfers use the same encoding in AXICTL[2-5]).
This feature is not advertised and has to be described by the
static mask associated with the device id.

Subject: coresight tmc: Support for save-restore in ETR

The Coresight SoC 600 TMC ETR supports save-restore feature,
where the values of the RRP/RWP and STS.Full are retained
when it leaves the Disabled state. Hence, we must program the
RRP/RWP and STS.Full to a proper value. For now, set the RRP/RWP
to the base address of the buffer and clear the STS.Full register.
This can be later exploited for proper save-restore of ETR
trace contexts (e.g, perf).

Subject: coresight tmc: Add support for Coresight SoC 600 TMC

The coresight SoC 600 supports ETR save-restore which allows us
to restore a trace session by retaining the RRP/RWP/STS.Full values
when the TMC leaves the Disabled state. However, the TMC doesn't
have a scatter-gather unit in built.

Also, TMCs have different PIDs in different configurations (ETF,
ETB & ETR), unlike the previous generation.

While the DEVID exposes some of the features/changes in the TMC,
it doesn't explicitly advertises the new save-restore feature
as described above.

>From what I can tell, we don't really need to treat ch_addr as
anything besides a pointer, and we can just do pointer math
instead of ORing in the bits of the offset and achieve the same
thing.

Also, we were passing a drvdata pointer to the
coresight_timeout() function, but we really wanted to pass the
address of the register base. Luckily the base is the first
member of the structure, so everything works out, but this is
quite unsafe if we ever change the structure layout. Clean this
all up so sparse stops complaining on this code.

Subject: tty: resolve tty contention between kernel and user space

The commit 12e84c71b7d4 ("tty: export tty_open_by_driver") exports
tty_open_by_device to allow tty to be opened from inside kernel which
works fine except that it doesn't handle contention with user space or
another kernel-space open of the same tty. For example, opening a tty
from user space while it is kernel opened results in failure and a
kernel log message about mismatch between tty->count and tty's file
open count.

This patch makes kernel access to tty exclusive, so that if a user
process or kernel opens a kernel opened tty, it gets -EBUSY. It does
this by adding TTY_KOPENED flag to tty->flags. When this flag is set,
tty_open_by_driver returns -EBUSY. Instead of overloading
tty_open_by_driver for both kernel and user space, this
patch creates a separate function tty_kopen which closely follows
tty_open_by_driver. tty_kclose closes the tty opened by tty_kopen.

To address the mismatch between tty->count and #fd's, this patch adds
#kopen's to the count before comparing it with tty->count. That way
check_tty_count reflects correct usage count.

Returning -EBUSY on tty open is a change in the interface. I have
tested this with minicom, picocom and commands like "echo foo >
/dev/ttyS0". They all correctly report "Device or resource busy" when
the tty is already kernel opened.

Subject: tty: undo export of tty_open_by_driver

Since we have tty_kopen, we no longer need to export tty_open_by_driver.
This patch makes this function static.

Subject: thunderbolt: Allow clearing the key

If secure authentication of a devices fails, either because the device
already has another key uploaded, or there is some other error sending
challenge to the device, and the user only wants to approve the device
just once (without a new key being uploaded to the device) the current
implementation does not allow this because the key cannot be cleared
once set even if we allow it to be changed.

Make this scenario possible and allow clearing the key by writing
empty string to the key sysfs file.

Subject: thunderbolt: Fix reset response_type

There is a mistake here where we accidentally use sizeof(TB_CFG_PKG_RESET)
instead of just TB_CFG_PKG_RESET.  The size of an int is 4 so it's the
same as TB_CFG_PKG_NOTIFY_ACK.

Subject: dm rq: do not update rq partially in each ending bio

We don't need to update the original dm request partially when ending
each cloned bio: just update original dm request once when the whole
cloned request is finished.  This still allows full support for partial
completion because a new 'completed' counter accounts for incremental
progress as the clone bios complete.

Partial request update can be a bit expensive, so we should try to avoid
it, especially because it is run in softirq context.

Avoiding all the partial request updates fixes both hard lockup and
soft lockups that were easily reproduced while running Laurence's
test[1] on IB/SRP.

BTW, after d4acf3650c7c ("block: Make blk_mq_delay_kick_requeue_list()
rerun the queue at a quiet time"), we need to make the test more
aggressive for reproducing the lockup:

	1) run hammer_write.sh 32 or 64 concurrently.
	2) write 8M each time

From 2071a3e94abd34d65bd40f1ff845f9cea300dfa6 Mon Sep 17 00:00:00 2001
From: Federico Vaga <federico.vaga@cern.ch>
Date: Tue, 18 Jul 2017 08:33:03 +0200
Subject: drivers/fmc: The only way to dump the SDB is from debugfs

Driver should not call fmc_sdb_dump() anymore. (actually they can but the
operation is not supported, so it will print an error message)

Subject: xen: xen-pciback: remove DRIVER_ATTR() usage

It's better to be explicit and use the DRIVER_ATTR_RW() and
DRIVER_ATTR_RO() macros when defining a driver's sysfs file.

Bonus is this fixes up a checkpatch.pl warning.

This is part of a series to drop DRIVER_ATTR() from the tree entirely.

Subject: md: Runtime support for multiple ppls

Increase PPL area to 1MB and use it as circular buffer to store PPL. The
entry with highest generation number is the latest one. If PPL to be
written is larger then space left in a buffer, rewind the buffer to the
start (don't wrap it).

Subject: raid5-ppl: Recovery support for multiple partial parity logs

Search PPL buffer in order to find out the latest PPL header (the one
with largest generation number) and use it for recovery. The PPL entry
format and recovery algorithm are the same as for single PPL approach.

Subject: android: binder: Add allocator selftest

binder_alloc_selftest tests that alloc_new_buf handles page allocation and
deallocation properly when allocate and free buffers. The test allocates 5
buffers of various sizes to cover all possible page alignment cases, and
frees the buffers using a list of exhaustive freeing order.

Test: boot the device with ANDROID_BINDER_IPC_SELFTEST config option
enabled. Allocator selftest passes.

Subject: android: binder: Move buffer out of area shared with user space

Binder driver allocates buffer meta data in a region that is mapped
in user space. These meta data contain pointers in the kernel.

This patch allocates buffer meta data on the kernel heap that is
not mapped in user space, and uses a pointer to refer to the data mapped.

Subject: android: binder: Add global lru shrinker to binder

Hold on to the pages allocated and mapped for transaction
buffers until the system is under memory pressure. When
that happens, use linux shrinker to free pages. Without
using shrinker, patch "android: binder: Move buffer out
of area shared with user space" will cause a significant
slow down for small transactions that fit into the first
page because free list buffer header used to be inlined
with buffer data.

In addition to prevent the performance regression for
small transactions, this patch improves the performance
for transactions that take up more than one page.

Modify alloc selftest to work with the shrinker change.

Test: Run memory intensive applications (Chrome and Camera)
to trigger shrinker callbacks. Binder frees memory as expected.
Test: Run binderThroughputTest with high memory pressure
option enabled.

Subject: firmware: vpd: use memunmap instead of iounmap

In functions vpd_sections_init() and vpd_section_init(), iounmap() is
used to unmap memory. However, in these cases, memunmap() should be
used.

Subject: misc: eeprom_93xx46: Simplify the usage of gpiod API

Commit 3ca9b1ac28398c ("misc: eeprom_93xx46: Add support for a GPIO
'select' line.") introduced the optional usage of 'select-gpios'
by using the gpiod API in a convoluted way.

Rewrite the gpiod handling to make the code simpler.

Subject: misc: apds990x: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.

Subject: misc: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: applicom: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

Subject: mux: convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Declare bin_attribute structures as const as they are only passed as an
argument to the function device_create_bin_file. This argument is of
type const, so declare the structure as const.

Subject: w1: ds2438: make several functions static

The functions w1_ds2438_get_page, w1_ds2438_get_temperature,
w1_ds2438_change_config_bit and w1_ds2438_get_voltage are local to
the source and do not need to be in global scope, so make it static.

Cleans up sparse warnings:
symbol 'w1_ds2438_get_page' was not declared. Should it be static?
symbol 'w1_ds2438_get_temperature' was not declared. Should it be static?
symbol 'w1_ds2438_change_config_bit' was not declared. Should it be static?
symbol 'w1_ds2438_get_voltage' was not declared. Should it be static?

Subject: drivers: w1: Extend 1W master driver DS2482 with module option to
 support PPM/SPU/1WS features

Extend the one wire DS2482 master driver with a module option that allows support
for PPM/SPU/1WS interface modes to be requested. This allows support of chips
that require one or more of these features such as the DS28E05.

 EDAC pnd2: Failed to register device with error -19.

On Denverton micro-server, the presence of the P2SB bridge PCI device is
enabled or disabled by the item 'RelaxSecConf' in BIOS setup menu. When
'RelaxSecConf' is enabled, the P2SB PCI device is present and the pnd2_edac
EDAC driver also uses it to get BAR. Hiding the P2SB PCI device caused the
pnd2_edac EDAC driver failed to get BAR then reported the above failure.

Therefor, store the presence state of P2SB PCI device before unhiding it
for reading BAR and restore the presence state after reading BAR.

Subject: nvmem: lpc18xx-eeprom: explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

"p" is the list iterator so it can't be NULL.  Static checkers complain
about this unnecessary check because we dereference the list iterator to
get the next item in the list so we'd be in trouble if it really was
NULL.  I have removed the check.

Subject: drm/vmwgfx: Don't use drm_irq_[un]install

We're not allowed to change the upstream version of the drm_irq_install
function to be able to incorporate threaded irqs. So roll our own irq
install- and uninstall functions instead of relying on the drm core ones.

Subject: drm/vmwgfx: Move irq bottom half processing to threads

This gets rid of the irq bottom half tasklets and instead performs the
work needed in process context. We also convert irq-disabling spinlocks to
ordinary spinlocks.

This should decrease system latency for other system components, like
sound for example but has the potential to increase latency for processes
that wait on the GPU.

Subject: drm/vmwgfx: Restart command buffers after errors

Previously we skipped the command buffer and added an extra fence to
avoid hangs due to skipped fence commands.
Now we instead restart the command buffer after the failing command,
if there are any commands left.
In addition we print out some information about the failing command
and its location in the command buffer.

Testing Done: ran glxgears using mesa modified to send the NOP_ERROR
command before each 10th clear and verified that we detected the device
error properly and that there were no other device errors caused by
incorrectly ordered command buffers. Also ran the piglit "quick" test
suite which generates a couple of device errors and verified that
they were handled as intended.

Subject: drm/vmwgfx: Support the NOP_ERROR command

Can be used by user-space applications to test and verify the kernel
command buffer error recovery functionality.

Malicious user-space apps could potentially use this command to slow down
graphics processing somewhat, but they could also accomplish the same thing
using a random malformed command so this should be considered safe.
At least as safe as it gets.

Subject: dm integrity: optimize writing dm-bufio buffers that are partially
 changed

Rather than write the entire dm-bufio buffer when only a subset is
changed, improve dm-bufio (and dm-integrity) by only writing the subset
of the buffer that changed.

Update dm-integrity to make use of dm-bufio's new
dm_bufio_mark_partial_buffer_dirty() interface.

Subject: dm: constify argument arrays

The arrays of 'struct dm_arg' are never modified by the device-mapper
core, so constify them so that they are placed in .rodata.

(Exception: the args array in dm-raid cannot be constified because it is
allocated on the stack and modified.)

Subject: drm/vmwgfx: Add export fence to file descriptor support

Added code to link a fence to a out_fence_fd file descriptor and
thread out_fence_fd down to vmw_execbuf_copy_fence_user() so it can be
copied into the IOCTL reply and be passed back up the the user.

v2:
Make sure to sync and clean up in case of failure

As seen from the implementation of the single class shutdown hook this
is not very sound design.

Rename the class shutdown hook to shutdown_pre to make it clear it runs

From: Andrew Jeffery <andrew@aj.id.au>
Date: Tue, 15 Aug 2017 16:51:02 +0930
Subject: i2c: aspeed: Retain delay/setup/hold values when configuring bus
 frequency

In addition to the base, low and high clock configuration, the AC timing
register #1 on the AST2400 houses fields controlling:

1. tBUF: Minimum delay between Stop and Start conditions
2. tHDSTA: Hold time for the Start condition
3. tACST: Setup time for Start and Stop conditions, and hold time for the
   Repeated Start condition

These values are defined in hardware on the AST2500 and therefore don't
need to be set.

aspeed_i2c_init_clk() was performing a direct write of the generated
clock values rather than a read/mask/modify/update sequence to retain
tBUF, tHDSTA and tACST, and therefore cleared the tBUF, tHDSTA and tACST
fields on the AST2400. This resulted in a delay/setup/hold time of 1
base clock, which in some configurations is not enough for some devices
(e.g. the MAX31785 fan controller, with an APB of 48MHz and a desired
bus speed of 100kHz).

Subject: power: supply: max17042_battery: Fix ACPI interrupt issues

On some x86/ACPI boards the DSDT defines an ACPI event handler for
the max17047 IRQ, this causes several problems:

1) We need to share the IRQ to avoid an error getting it

2) Even of we are willing to share, we may fail to share because some
   DSDTs claim it exclusivly

3) If we are unable to share the IRQ, or the IRQ is only listed as an
   ACPI event source and not in the max1704 firmware node, then the
   charge threshold IRQ (which is used to give an IRQ every 1 percent
   charge change) becomes a problem, the ACPI event handler will not
   update this to the next 1 percent threshold, so the IRQ keeps firing
   and we get an IRQ storm pegging 1 CPU core.

   This happens despite the max17042 driver not setting the charge
   threshold because Windows uses it and leaves it set on reboot.

   So if we are unable to get the IRQ we need to reprogram the
   charge threshold to its disabled setting.

This commit fixes al of the above, while at it it also makes the error
msg when being unable to get the IRQ consistent with other messages.

Subject: dmaengine: ti-dma-crossbar: Fix dra7 reserve function

DMA crossbar uses 'xbar->dma_inuse' variable to manage allocated routes.
Each bit represents respective DMA channel. If the channel is free, bit
is set to '0', if channel is allocated, bit should be set to '1'.

In reserve function, the bits for requested DMA channels are cleared, so
they are not really reserved, but freed and become ready for allocation.

Subject: Input: PS/2 gpio bit banging driver for serio bus

This driver provides PS/2 serio bus support by implementing bit banging
with the GPIO API. The GPIO pins, data and clock, can be configured with
a node in the device tree or by generic device properties (GDP).

Writing to a device is supported as well, though it is possible timings
can not be halt as they are tough and difficult to reach with bit banging.
Therefore it can be configured (also in DT and GDP) whether the serio
write function should be available for clients.

This driver is for development purposes and not recommended for productive
use. However, this driver can be useful e.g. when no USB port is available
or using old peripherals is desired as PS/2 controller chips getting rare.

This driver was tested on bcm2825 and on Kirin 960 and it worked well
together with the atkbd and psmouse driver.

Subject: Input: synaptics - fix device info appearing different on reconnect

User-modified input settings no longer survive a suspend/resume cycle.
Starting with 4.12, the touchpad is reinitialized on every reconnect
because the hardware appears to be different. This can be reproduced
by running the following as root:

    echo -n reconnect >/sys/devices/platform/i8042/serio1/drvctl

A line like the following will show up in dmesg:

    [30378.295794] psmouse serio1: synaptics: hardware appears to be
                   different: id(149271-149271), model(114865-114865),
                   caps(d047b3-d047b1), ext(b40000-b40000).

Note the single bit difference in caps: bit 1 (SYN_CAP_MULTIFINGER).

This happens because we modify our stored copy of the device info
capabilities when we enable advanced gesture mode but this change is
not reflected in the actual hardware capabilities.

It worked in the past because synaptics_query_hardware used to modify
the stored synaptics_device_info struct instead of filling in a new
one, as it does now.

Fix it by no longer faking the SYN_CAP_MULTIFINGER bit when setting
advanced gesture mode. This necessitated a small refactoring.

Fixes: 6c53694fb222 ("Input: synaptics - split device info into a separate structure")

Subject: pata_octeon_cf: use of_property_read_{bool|u32}()

The Octeon CF driver basically  open-codes of_property_read_{bool|u32}()
using  of_{find|get}_property() calls in its  probe() method.  Using the
modern DT APIs saves 2 LoCs and 16 bytes of object code (MIPS gcc 3.4.3).

Subject: cdc_ncm: flag the u-blox TOBY-L4 as wwan

The u-blox TOBY-L4 is a LTE Advanced (Cat 6) module with HSPA+ and 2G
fallback.

Unlike the TOBY-L2, this module has one single USB layout and exposes
several TTYs for control and a NCM interface for data. Connecting this
module may be done just by activating the desired PDP context with
'AT+CGACT=1,<cid>' and then running DHCP on the NCM interface.

Subject: net: mvpp2: fix the mac address used when using PPv2.2

The mac address is only retrieved from h/w when using PPv2.1. Otherwise
the variable holding it is still checked and used if it contains a valid
value. As the variable isn't initialized to an invalid mac address
value, we end up with random mac addresses which can be the same for all
the ports handled by this PPv2 driver.

Fixes this by initializing the h/w mac address variable to {0}, which is
an invalid mac address value. This way the random assignation fallback
is called and all ports end up with their own addresses.

Subject: PCI: rockchip: Add per-lane PHY support

We distinguish the legacy PHY from newer per-lane PHYs by adding legacy_phy
flag.  Note that the legacy PHY is still the first option to be searched in
order not to break the backward compatibility of DTB.

Subject: tty: serial: sprd: fix error return code in sprd_probe()

platform_get_irq() returns an error code, but the sprd_serial driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Also, notice that platform_get_irq() no longer returns 0 on error:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

Subject: serial: pch_uart: Remove unneeded NULL check

There is no need to do a NULL check for debugfs_remove().

Quoting Documentation/filesystems/debugfs.txt:

"The dentry value can be NULL, in which case nothing will be removed."

, so remove the unneeded NULL check.

Subject: tty: serial: msm: Move request_irq to the end of startup

Move the request_irq() call to the end of the msm_startup(),
so that we don't handle interrupts while msm_startup() is
running. This avoids potential races while initialization
is in progress. For example, consider below scenario
where rx handler reads the intermediate value of dma->chan,
set in msm_request_rx_dma(), and tries to do dma mapping,
which results in data abort.

uart_port_startup()
  msm_startup()
   request_irq()
   ...
   msm_request_rx_dma()
    ...
    dma->chan = dma_request_slave_channel_reason(dev, "rx");
    <UART RX IRQ>
     msm_uart_irq()
      msm_handle_rx_dm()
       msm_start_rx_dma()
        dma->desc = dma_map_single()
         <data abort>

Subject: serial: pch_uart: Make port type explicit

It used to be a gap in port definitions after PORT_MAX_8250. Since the
new drivers are coming the gap become shorter and shorter until the
commit a2d6a987bfe4 ("serial: 8250: Add new port type for TI DA8xx/66AK2x")
completely removed it.

So, while type here is just a formality, make things a little bit more
explicit for this driver and move port types to UAPI header. Note,
it uses two types for now.

Subject: serial: core: Consider rs485 settings to drive RTS

Previously the rs485 settings weren't considered when setting the RTS
line, so e.g. closing and reopening a port made serial_core to drive
the line as if rs485 was disabled.

This patch fixes those issues.

Subject: serial: 8250: Use hrtimers for rs485 delays

Previously the timers where based on the classic timers, giving a too
coarse resolution on systems with configs of less than 1000 HZ.

This patch changes the rs485 timers to hrtimers.

Subject: serial: 8250_of: Add basic PM runtime support

66AK2G UART instances are not apart of the ALWAYS_ON power domain.
Therefore, pm_runtime calls must be made to properly insure the appropriate
power domains needed by UART are on. Keep legacy clk api calls since other
users of this driver may not support PM runtime.

Subject: tty: 8250: constify parisc_device_id

parisc_device_id are not supposed to change at runtime. All functions
working with parisc_device_id provided by <asm/parisc-device.h> work
with const parisc_device_id. So mark the non-const structs as const.

Subject: serial: earlycon: Only try fdt when specify 'earlycon' exactly

When moving earlycon early_param handling to serial, the devicetree
earlycons enable condition changed slightly.

We used to only do that for 'console'/'earlycon', but now would also
for 'console='/'earlycon='.

Fix it by using the same condition like before.

Subject: serial: 8250: of: Add new port type for MediaTek BTIF controller on
 MT7622/23 SoC

MediaTek BTIF controller is the serial interface similar to UART but it
works only as the digital device which is mainly used to communicate with
the connectivity module called CONNSYS inside the SoC which could be mostly
found on those MediaTek SoCs with Bluetooth feature such as MT7622 and
MT7623 SoCs.

And the controller is made as being compatible with the 8250 register
layout with extra registers such as DMA enablement so it tends to be
integrated with reusing 8250 OF driver. However, DMA mode is not being
supported yet in the current driver.

Subject: serial: 8250_uniphier: fix serial port index in private data

serial8250_register_8250_port() may allocate a different port index
than requested.  The driver needs to remember the returned value of
serial8250_register_8250_port() for later use.  Otherwise, the .remove
hook may unregister a different port.

Subject: serial: 8250_uniphier: use CHAR register for canary to detect
 power-off

The 8250 core uses the SCR as a canary to discover if the console has
been powered-off.

This hardware does not have SCR at offset 7, but an unused register
CHAR at a different offset.  As long as the character interrupt is
disabled, the register access has no impact, so it is useful as an
alternative scratch register.

Subject: tty: serial: imx: disable irq after suspend

If any key on console is pressed when board is suspended,
board hangs.

Driver's interrupt handler must be guaranteed not to run while
resume/suspend_noirq() are being executed. See include/linux/pm.h
for details.

Tested on i.MX6 based board.

The idea of this fix is based on commit in official i.MX kernel tree:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git
commit 81e8e7d91d81 ("tty: serial: imx: disable irq after suspend")

Disable rx irq after suspend to avoid interrupt coming in early resume.

Subject: serial: imx: Avoid post-PIO cleanup if TX DMA is started
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The imx_transmit_buffer function should return if TX DMA has already
been started and not just skip over the buffer PIO write loop. (Which
did fix the initial problem, but could have unintentional side-effects)

Tested on an i.MX6Q board with half-duplex RS-485 and with RS-232.

Subject: Introduce 8250_men_mcb

This patch introduces the 8250_men_mcb driver for the MEN 16Z125
IP-Core. This is a 16550-type UART with a 60 byte FIFO.
Due to strange old hardware, every board using this IP core requires
different values for uartclk. A reasonable default is included in
addition to the support of three boards. Additional values for other
boards will be added later.

This v2 has some whitespace fixes, I screwed this up yesterday.

Subject: pty: show associative slave of ptmx in fdinfo

This patch adds "tty-index" field to /proc/PID/fdinfo/N if N
specifies /dev/ptmx. The field shows the index of associative
slave pts.

Though a minor number is given for each pts instance, ptmx is not.
It means there is no way in user-space to know the association between
file descriptors for pts/n and ptmx. (n = 0, 1, ...)

This is different from pipe. About pipe such association can be solved
by inode of pipefs.

Providing the way to know the association between pts/n and ptmx helps
users understand the status of running system. lsof can utilize this field.

Subject: drm: kirin: Add mode_valid logic to avoid mode clocks we can't
 generate

Currently the hikey dsi logic cannot generate accurate byte
clocks values for all pixel clock values. Thus if a mode clock
is selected that cannot match the calculated byte clock, the
device will boot with a blank screen.

This patch uses the new mode_valid callback (many thanks to
Jose Abreu for upstreaming it!) to ensure we don't select
modes we cannot generate.

Also, since the ade crtc code will adjust the mode in mode_set,
this patch also adds a mode_fixup callback which we use to make
sure we are validating the mode clock that will eventually be
used.

Subject: nvme: add support for FW activation without reset

This patch adds support for handling Fw activation without reset
On completion of FW-activation-starting AER, all queues are
paused till CSTS.PP is cleared or timed out (exceeds max time for
fw activtion MTFA). If device fails to clear CSTS.PP within MTFA,
driver issues reset controller.

Subject: nvme: add support for NVMe 1.3 Timestamp Feature

NVME's Timestamp feature allows controllers to be aware of the epoch
time in milliseconds. This patch adds the set features hook for various
transports through the identify path, so that resets and resumes can
update the controller as necessary.

Subject: nvme-rdma: stop queues instead of simply flipping their state

If we move the queues from LIVE state, we might as well stop them (drain
for rdma).  Do it after we stop the request queues to prevent a stray
request sneaking in .queue_rq after we stop the queue.

Give it a name symmetric to nvme_rdma_free_queue. Also pass in the ctrl
sqsize+1 and not the opts queue_size.  And suppress a superflous
failure message.

Subject: nvme-rdma: introduce nvme_rdma_start_queue

This should pair with nvme_rdma_stop_queue.  While this is not a complete
inverse, it still pairs up pretty well because in fabrics we don't have a
disconnect capsule (yet) but we simply teardown the transport association.

Subject: nvme-fc: Reattach to localports on re-registration

If the LLDD resets or detaches from an fc port, the LLDD will
deregister all remoteports seen by the fc port and deregister the
localport associated with the fc port. The teardown of the localport
structure will be held off due to reference counting until all the
remoteports are removed (and they are held off until all
controllers/associations to terminated). Currently, if the fc port
is reinit/reattached and registered again as a localport it is
treated as an independent entity from the prior localport and all
prior remoteports and controllers cannot be revived. They are
created as new and separate entities.

This patch changes the localport registration to look at the known
localports that are waiting to be torndown. If they are the same port
based on wwn's, the local port is transitioned out of the teardown
state.  This allows the remote ports and controller connections to
be reestablished and resumed as long as the localport can also be
reregistered within the timeout windows.

The patch adds a new routine nvme_fc_attach_to_unreg_lport() with
the functionality and moves the lport get/put routines to avoid
forward references.

Subject: nvmet-fc: simplify sg list handling

The existing nvmet_fc sg list handling has 2 faults:
a) the request between LLDD and transport has too large of an sg
   list (256 elements), which is normally 256k (64 elements).
b) sglist handling doesn't optimize on the fact that each element
   is a page.

This patch removes the static sg list in the request and uses the
dynamic list already present in the nvmet_fc transport. It also
simplies the handling of the sg list on multiple sequences to
take advantage of the per-page divisions.

The value of iod->first_dma ends up as prp2 in NVMe commands. In case
there is not enough data to cross a page boundary, iod->first_dma is
never initialized and contains random data.

Comply with the NVMe specification and fill in 0 in that case.

If an NVMe controller reports RTD3 Entry Latency larger than
shutdown_timeout, up to a maximum of 60 seconds, use that value to set
the shutdown timer. Otherwise fall back to the module parameter which
defaults to 5 seconds.

Subject: drm/syncobj: Add a race-free drm_syncobj_fence_get helper (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The atomic exchange operation in drm_syncobj_replace_fence is sufficient
for the case where it races with itself.  However, if you have a race
between a replace_fence and dma_fence_get(syncobj->fence), you may end
up with the entire replace_fence happening between the point in time
where the one thread gets the syncobj->fence pointer and when it calls
dma_fence_get() on it.  If this happens, then the reference may be
dropped before we get a chance to get a new one.  The new helper uses
dma_fence_get_rcu_safe to get rid of the race.

This is also needed because it allows us to do a bit more than just get
a reference in drm_syncobj_fence_get should we wish to do so.

v2:
 - RCU isn't that scary
 - Call rcu_read_lock/unlock
 - Don't rename fence to _fence
 - Make the helper static inline

Subject: drm/syncobj: add sync obj wait interface. (v8)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This interface will allow sync object to be used to back
Vulkan fences. This API is pretty much the vulkan fence waiting
API, and I've ported the code from amdgpu.

v2: accept relative timeout, pass remaining time back
to userspace.
v3: return to absolute timeouts.
v4: absolute zero = poll,
    rewrite any/all code to have same operation for arrays
    return -EINVAL for 0 fences.
v4.1: fixup fences allocation check, use u64_to_user_ptr
v5: move to sec/nsec, and use timespec64 for calcs.
v6: use -ETIME and drop the out status flag. (-ETIME
is suggested by ickle, I can feel a shed painting)
v7: talked to Daniel/Arnd, use ktime and ns everywhere.
v8: be more careful in the timeout calculations
    use uint32_t for counter variables so we don't overflow
    graciously handle -ENOINT being returned from dma_fence_wait_timeout

Subject: drm/syncobj: Add a callback mechanism for replace_fence (v3)

It is useful in certain circumstances to know when the fence is replaced
in a syncobj.  Specifically, it may be useful to know when the fence
goes from NULL to something valid.  This does make syncobj_replace_fence
a little more expensive because it has to take a lock but, in the common
case where there is no callback list, it spends a very short amount of
time inside the lock.

v2:
 - Don't lock in drm_syncobj_fence_get.  We only really need to lock
   around fence_replace to make the callback work.
v3:
 - Fix the cb_list comment to make kbuild happy

Subject: drm/syncobj: Add a CREATE_SIGNALED flag

This requests that the driver create the sync object such that it
already has a signaled dma_fence attached.  Because we don't need
anything in particular (just something signaled), we use a dummy null
fence.  This is useful for Vulkan which has a similar flag that can be
passed to vkCreateFence.

Subject: drm/syncobj: Allow wait for submit and signal behavior (v5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Vulkan VkFence semantics require that the application be able to perform
a CPU wait on work which may not yet have been submitted.  This is
perfectly safe because the CPU wait has a timeout which will get
triggered eventually if no work is ever submitted.  This behavior is
advantageous for multi-threaded workloads because, so long as all of the
threads agree on what fences to use up-front, you don't have the extra
cross-thread synchronization cost of thread A telling thread B that it
has submitted its dependent work and thread B is now free to wait.

Within a single process, this can be implemented in the userspace driver
by doing exactly the same kind of tracking the app would have to do
using posix condition variables or similar.  However, in order for this
to work cross-process (as is required by VK_KHR_external_fence), we need
to handle this in the kernel.

This commit adds a WAIT_FOR_SUBMIT flag to DRM_IOCTL_SYNCOBJ_WAIT which
instructs the IOCTL to wait for the syncobj to have a non-null fence and
then wait on the fence.  Combined with DRM_IOCTL_SYNCOBJ_RESET, you can
easily get the Vulkan behavior.

v2:
 - Fix a bug in the invalid syncobj error path
 - Unify the wait-all and wait-any cases
v3:
 - Unify the timeout == 0 case a bit with the timeout > 0 case
 - Use wait_event_interruptible_timeout
v4:
 - Use proxy fence
v5:
 - Revert to a combination of v2 and v3
 - Don't use proxy fences
 - Don't use wait_event_interruptible_timeout because it just adds an
   extra layer of callbacks

Subject: drm/syncobj: Add a syncobj_array_find helper

The wait ioctl has a bunch of code to read an syncobj handle array from
userspace and turn it into an array of syncobj pointers.  We're about to
add two new IOCTLs which will need to work with arrays of syncobj
handles so let's make some helpers.

Subject: PCI: iproc: Work around Stingray CRS defects
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Configuration Request Retry Status ("CRS") completions are a required part
of PCIe.  A PCIe device may respond to config a request with a CRS
completion to indicate that it needs more time to initialize.  A Root Port
that receives a CRS completion may automatically retry the request, or it
may treat the request as a failed transaction.  For a failed read, it will
likely synthesize all 1's data, i.e., 0xffffffff, to complete the read to
the CPU.

CRS Software Visibility ("CRS SV") is an optional feature.  Per PCIe r3.1,
sec 2.3.2, if supported and enabled, a Root Port that receives a CRS
completion for a config read of the Vendor ID will synthesize 0x0001 data
(an invalid Vendor ID) instead of retrying or failing the transaction.  The
0x0001 data makes the CRS completion visible to software, so it can perform
other tasks while waiting for the device.

The iProc "Stingray" PCIe controller does not support CRS completions
correctly.  From the Stingray PCIe Controller spec:

  4.7.3.3. Retry Status On Configuration Cycle

  Endpoints are allowed to generate retry status on configuration cycles.
  In this case, the RC needs to re-issue the request. The IP does not
  handle this because the number of configuration cycles needed will
  probably be less than the total number of non-posted operations needed.

  When a retry status is received on the User RX interface for a
  configuration request that was sent on the User TX interface, it will be
  indicated with a completion with the CMPL_STATUS field set to 2=CRS, and
  the user will have to find the address and data values and send a new
  transaction on the User TX interface.  When the internal configuration
  space returns a retry status during a configuration cycle (user_cscfg =
  1) on the Command/Status interface, the pcie_cscrs will assert with the
  pcie_csack signal to indicate the CRS status.

  When the CRS Software Visibility Enable register in the Root Control
  register is enabled, the IP will return the data value to 0x0001 for the
  Vendor ID value and 0xffff  (all 1’s) for the rest of the data in the
  request for reads of offset 0 that return with CRS status.  This is true
  for both the User RX Interface and for the Command/Status interface.
  When CRS Software Visibility is enabled, the CMPL_STATUS field of the
  completion on the User RX Interface will not be 2=CRS and the pcie_cscrs
  signal will not assert on the Command/Status interface.

The Stingray hardware never reissues configuration requests when it
receives CRS completions.  Contrary to what sec 4.7.3.3 above says, when it
receives a CRS completion, it synthesizes 0xffff0001 data regardless of the
address of the read or the value of the CRS SV enable bit.

This is broken in two ways:

  1) When CRS SV is disabled, the Root Port should never synthesize the
  0x0001 value.  If it receives a CRS completion, it should fail the
  transaction and synthesize all 1's data.

  2) When CRS SV is enabled, the Root Port should only synthesize 0x0001
  data if it receives a CRS completion for a read of the Vendor ID.  If it
  receives a CRS completion for any other read, it should fail the
  transaction and synthesize all 1's data.

This breaks pci_flr_wait(), which reads the Command register and expects to
see all 1's data if the read fails because of CRS completions.  On
Stingray, it sees the incorrect 0xffff0001 data instead.

It also breaks config registers that contain the 0xffff0001 value.  If we
read such a register, software can't distinguish a CRS completion from the
actual value read from the device.

On Stingray, if we read 0xffff0001 data, assume this indicates a CRS
completion and retry the read for 500ms.  If we time out, return all 1's
(0xffffffff) data.  Note that this corrupts registers that happen to
contain 0xffff0001.

Stingray advertises CRS SV support in its Root Capabilities register, and
the CRS SV enable bit is writable (even though the hardware ignores it).
Mask out PCI_EXP_RTCAP_CRSVIS so software doesn't try to use CRS SV.

Subject: xen-netback: update ubuf_info initialization to anonymous union

The xen driver initializes struct ubuf_info fields using designated
initializers. I recently moved these fields inside a nested anonymous
struct inside an anonymous union. I had missed this use case.

This breaks compilation of xen-netback with older compilers.
>From kbuild bot with gcc-4.4.7:

   drivers/net//xen-netback/interface.c: In function
   'xenvif_init_queue':
   >> drivers/net//xen-netback/interface.c:554: error: unknown field 'ctx' specified in initializer
   >> drivers/net//xen-netback/interface.c:554: warning: missing braces around initializer
      drivers/net//xen-netback/interface.c:554: warning: (near initialization for '(anonymous).<anonymous>')
   >> drivers/net//xen-netback/interface.c:554: warning: initialization makes integer from pointer without a cast
   >> drivers/net//xen-netback/interface.c:555: error: unknown field 'desc' specified in initializer

Add double braces around the designated initializers to match their
nested position in the struct. After this, compilation succeeds again.

Subject: nfp: fix supported key layers calculation

Previously when calculating the supported key layers MPLS, IPv4/6
TTL and TOS were not considered. This patch checks that the TTL and
TOS fields are masked out before offloading. Additionally this patch
checks that MPLS packets are correctly handled, by not offloading them.

Since the bindings have been controversial, and we follow the DT stable ABI
rule, we shouldn't let a driver with a DT binding that might change slip
through in a stable release.

Remove the compatibles to make sure the driver will not probe and no-one
will start using the binding currently implemented. This commit will
obviously need to be reverted in due time.

Subject: cpufreq: imx6q: Fix imx6sx low frequency support

This patch contains the minimal changes required to support imx6sx OPP
of 198 Mhz. Without this patch cpufreq still reports success but the
frequency is not changed, the "arm" clock will still be at 396000000 in
clk_summary.

In order to do this PLL1 needs to be still kept enabled while changing
the ARM clock. This is a hardware requirement: when ARM_PODF is changed
in CCM we need to check the busy bit of CCM_CDHIPR bit 16 arm_podf_busy,
and this bit is sync with PLL1 clock, so if PLL1 NOT enabled, this
bit will never get clear.

Keep pll1_sys explicitly enabled until after the rate is change to deal
with this. Otherwise from the clk framework perspective pll1_sys is
unused and gets turned off.

Subject: cxgb4: Fix stack out-of-bounds read due to wrong size to
 t4_record_mbox()

Passing commands for logging to t4_record_mbox() with size
MBOX_LEN, when the actual command size is actually smaller,
causes out-of-bounds stack accesses in t4_record_mbox() while
copying command words here:

	for (i = 0; i < size / 8; i++)
		entry->cmd[i] = be64_to_cpu(cmd[i]);

Up to 48 bytes from the stack are then leaked to debugfs.

This happens whenever we send (and log) commands described by
structs fw_sched_cmd (32 bytes leaked), fw_vi_rxmode_cmd (48),
fw_hello_cmd (48), fw_bye_cmd (48), fw_initialize_cmd (48),
fw_reset_cmd (48), fw_pfvf_cmd (32), fw_eq_eth_cmd (16),
fw_eq_ctrl_cmd (32), fw_eq_ofld_cmd (32), fw_acl_mac_cmd(16),
fw_rss_glb_config_cmd(32), fw_rss_vi_config_cmd(32),
fw_devlog_cmd(32), fw_vi_enable_cmd(48), fw_port_cmd(32),
fw_sched_cmd(32), fw_devlog_cmd(32).

The cxgb4vf driver got this right instead.

When we call t4_record_mbox() to log a command reply, a MBOX_LEN
size can be used though, as get_mbox_rpl() will fill cmd_rpl up
completely.

Subject: ACPI, APEI, EINJ: Subtract any matching Register Region from Trigger
 resources

ACPI defines a number of instructions to use for triggering errors. However
we are currently removing the address resources from the trigger resources
for only the WRITE_REGISTER_VALUE instruction. This leads to a resource
conflict for any other valid instruction.

Check that the instruction is less than or equal to the
WRITE_REGISTER_VALUE instruction. This allows all valid memory access
instructions and protects against invalid instructions.

The tty_alloc_driver() function never returns NULL, it returns error
pointers on error.

Subject: mlxsw: spectrum: compile-in dpipe support only if devlink is enabled

Makes no sense to have dpipe compiled in when devlink is not enabled,
because the devlink dpipe registation is noop function. So don't compile
it in. This also fixes missing extern structs errors.

Subject: IB/{qib, hfi1}: Avoid flow control testing for RDMA write operation

Section 9.7.7.2.5 of the 1.3 IBTA spec clearly says that receive
credits should never apply to RDMA write.

qib and hfi1 were doing that.  The following situation will result
in a QP hang:
- A prior SEND or RDMA_WRITE with immmediate consumed the last
  credit for a QP using RC receive buffer credits
- The prior op is acked so there are no more acks
- The peer ULP fails to post receive for some reason
- An RDMA write sees that the credits are exhausted and waits
- The peer ULP posts receive buffers
- The ULP posts a send or RDMA write that will be hung

The fix is to avoid the credit test for the RDMA write operation.

Subject: IB/hfi1: Improve local kmem_cache_alloc performance

Performance analysis shows that the cache callback function
sdma_kmem_cache_ctor contributes to 1/2 of the kmem_cache_allocs
time.

Since all of the fields in the allocated data structure are initialized
in the code path, remove the _ctor function.

Clean up hfi1_user_exp_rcv_setup function by moving page pinning and
unpinning related code to separate functions. In order to reduce the
number of parameters passed between functions, a new data structure
struct tid_user_buf is defined and used.

Subject: IB/hfi1: Fix the bail out code in pin_vector_pages() function

In pin_vector_pages() function, if there is any error while pinning the
pages or while adding a pinned buffer to the cache, the bail out code
needs to unpin any pinned pages that are not in the cache and adjust the
n_locked counter that counts the total pages pinned. The current bail
out code doesn't seem to be doing it right in two cases:

1. Before pinning required pages for a buffer, the SDMA pinned buffer
cache is searched to see if the virtual address range that needs to be
pinned is already pinned. If there isn't a hit in the cache, a new node
is created for the buffer and is added to the cache after the buffer is
pinned. If adding the new node to the cache fails, the n_locked count is
decremented properly but the pinned pages are not freed. This commit
fixes this issue.

2. If there is a hit in the SDMA cache, but the cached buffer doesn't
have enough pages to cover the entire address range that needs to be
pinned, the node for the cached buffer is extracted from the cache,
remaining pages needed are pinned and added to the node. The node is
finally added back into the cache. If there is an error pinning the
extra pages, the bail out code frees all the pages in the node but the
n_locked count is not being decremented by the no of pages in the node
that are freed. This commit fixes this issue.

This commit fixes the above two issues by creating a new function that
frees the pages in a node and decrements the n_locked count by the
number of pages freed.

Subject: IB/hfi1: Remove duplicate definitions of num_user_pages() function

num_user_pages() function has been defined in both user_exp_rcv.c file
and user_sdma.c file. Move the function definition to a header file so
there is only one definition in the source repo.

Subject: IB/hfi1: Move structure definitions from user_exp_rcv.c to

Clean up user_exp_rcv.c file by moving structure definitions into header
file user_exp_rcv.h. Since these structure definitions depend on the
structure definitions in mmu_rb.h, move #include "mmu_rb.h" above
the include "user_exp_rcv.h" or include of header files that include
user_exp_rcv.h

The hfi1_cdbg() macro can be instantiated in the hot path even when it
is not in use.  This shows up on perf profiles.

Rework the macros (for SDMA and MMU), to use the trace interface directly
to eliminate this performance hit.

Subject: IB/hfi1: Use accessor to determine ring size

The qp_stats print will soon be moving to rdmavt, so use the proper

Subject: IB/rdmavt: Add QP iterator API for QPs

There are currently 3 spots in the qib and hfi1 driver that have
knowledge of the internal QP hash list that should only be in
scope to rdmavt QP code.

Add an iterator API for processing all QPs to hide the
nature of the RCU hashlist.

The API consists of:
- rvt_qp_iter_init()
  * For iterating QPs one at a time for seq_file semantics
- rvt_qp_iter_next()
  * For iterating QPs one at a time for seq_file semantics
- rvt_qp_iter()
  * For iterating all QPs

The first two are used for things like seq_file prints.

The last is for code that just needs to iterate all QPs
in the system.

From 0208da90def5776cef940f9de4ffe6ecef346207 Mon Sep 17 00:00:00 2001
From: Mike Marciniszyn <mike.marciniszyn@intel.com>

Subject: IB/rdmavt: Handle dereg of inuse MRs properly

A destroy of an MR prior to destroying the QP can cause the following
diagnostic if the QP is referencing the MR being de-registered:

hfi1 0000:05:00.0: hfi1_0: rvt_dereg_mr timeout mr ffff8808562108
              00 pd ffff880859b20b00

The solution is to when the a non-zero refcount is encountered when
the MR is destroyed the QPs needs to be iterated looking for QPs in
the same PD as the MR.  If rvt_qp_mr_clean() detects any such QP
references the rkey/lkey, the QP needs to be put into an error state
via a call to rvt_qp_error() which will trigger the clean up of any
stuck references.

This solution is as specified in IBTA 1.3 Volume 1 11.2.10.5.

[This is reproduced with the 0.4.9 version of qperf and the rc_bw test]

Subject: IB/rxe: Move refcounting earlier in rxe_send()

The network stack will call nskb's destructor, rxe_skb_tx_dtor(), if the
packet gets dropped by ip_local_out()/ip6_local_out(). Thus we need to add
the QP ref before output to avoid extra dereferences during network
congestion. This could lead to unwanted destruction of the QP.

Fix up the skb_out accounting, too.

Subject: IB/rxe: Disable completion upcalls when a CQ is destroyed

This prevents the stack from accessing userspace objects while they
are being torn down.

One possible sequence of events:
 - Userspace program exits
 - ib_uverbs_cleanup_ucontext() runs, calling ib_destroy_qp(),
   ib_destroy_cq(), etc. and releasing/freeing the UCQ
   - The QP still has tasklets running, so it isn't destroyed yet
   - The CQ is referenced by the QP, so the CQ isn't destroyed yet
   - The UCQ is kfree()'d anyway
 - A send work request completes
 - rxe_send_complete() calls cq->ibcq.comp_handler()
 - ib_uverbs_comp_handler() runs and crashes; the event queue is checked
   for is_closed, but it has no way to check the ib_ucq_object before
   accessing it

The reference counting on the CQ doesn't protect against this since the CQ
hasn't been destroyed yet.
There's no available interface to deregister the UCQ from the CQ, and it
didn't appear that attempting to add reference counting to the UCQ was
going to be a good way to go since this solution is much simpler.

The resource array is sized by max_dest_rd_atomic, not max_rd_atomic.
Iterating over max_rd_atomic entries of qp->resp.resources[] will cause
incorrect behavior when the two attributes are different (or even
crash if max_rd_atomic is larger).

Subject: IB/rxe: Fix destination cache for IPv6

To successfully match an IPv6 path, the path cookie must match. Store it
in the QP so that the IPv6 path can be reused.

Replace open-coded version of dst_check() with the actual call, fixing the
logic. The open-coded version skips the check call if dst->obsolete is 0
(DST_OBSOLETE_NONE), proceeding to replace the route. DST_OBSOLETE_NONE
means that the route may continue to be used, though.

Subject: IB/rxe: Avoid ICRC errors by copying into the skb first

The current process is to first calculate the CRC and then copy the client
data into the packet. This leaves a window in which the packet contents and
CRC can get out of sync, if the client changes the data after the CRC is
calculated but before the data is copied.

By copying the data into the packet and then calculating the CRC directly
from the packet contents we eliminate the window.

This can be seen with qperf's ud_bi_bw test. This seems like very
strange/reckless client behavior, but whether the client has mangled its
data or not RXE should be able to transfer it reliably.

Subject: dpaa_eth: use multiple Rx frame queues

Add a block of 128 Rx frame queues per port. The FMan hardware will
send traffic on one of these queues based on the FMan port Parse
Classify Distribute setup. The hash computed by the FMan Keygen
block will select the Rx FQ.

Subject: dpaa_eth: enable Rx hashing control

Allow ethtool control of the Rx flow hashing. By default RSS is
enabled, this allows to turn it off by bypassing the FMan Keygen
block and sending all traffic on the default Rx frame queue.

Subject: ACPI / blacklist: add acpi_match_platform_list()

ACPI OEM ID / OEM Table ID / Revision can be used to identify
a platform based on ACPI firmware info.  acpi_blacklisted(),
intel_pstate_platform_pwr_mgmt_exists(), and some other funcs,
have been using similar check to detect a list of platforms
that require special handlings.

Move the platform check in acpi_blacklisted() to a new common
utility function, acpi_match_platform_list(), so that other
drivers do not have to implement their own version.

There is no change in functionality.

Subject: irda: move net/irda/ to drivers/staging/irda/net/

It's time to get rid of IRDA.  It's long been broken, and no one seems
to use it anymore.  So move it to staging and after a while, we can
delete it from there.

To start, move the network irda core from net/irda to
drivers/staging/irda/net/

+	tristate "IrDA (infrared) subsystem support"
+	select CRC_CCITT
+	---help---
+	  Say Y here if you want to build support for the IrDA (TM) protocols.
+	  The Infrared Data Associations (tm) specifies standards for wireless
+	  infrared communication and is supported by most laptops and PDA's.
+
+	  To use Linux support for the IrDA (tm) protocols, you will also need
+	  some user-space utilities like irattach.  For more information, see
+	  the file <file:Documentation/networking/irda.txt>.  You also want to
+	  read the IR-HOWTO, available at
+	  <http://www.tldp.org/docs.html#howto>.
+
+	  If you want to exchange bits of data (vCal, vCard) with a PDA, you
+	  will need to install some OBEX application, such as OpenObex :
+	  <http://sourceforge.net/projects/openobex/>
+
+	  To compile this support as a module, choose M here: the module will
+	  be called irda.

+	depends on IRDA
+	help
+	  Say Y here to support the connectionless Ultra IRDA protocol.
+	  Ultra allows to exchange data over IrDA with really simple devices
+	  (watch, beacon) without the overhead of the IrDA protocol (no handshaking,
+	  no management frames, simple fixed header).
+	  Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

+config IRDA_CACHE_LAST_LSAP
+	bool "Cache last LSAP"
+	depends on IRDA
+	help
+	  Say Y here if you want IrLMP to cache the last LSAP used.  This
+	  makes sense since most frames will be sent/received on the same
+	  connection.  Enabling this option will save a hash-lookup per frame.
+
+	  If unsure, say Y.
+
+config IRDA_FAST_RR
+	bool "Fast RRs (low latency)"
+	depends on IRDA
+	---help---
+	  Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
+	  when acting as a primary station.
+	  Disabling this option will make latency over IrDA very bad. Enabling
+	  this option will make the IrDA stack send more packet than strictly
+	  necessary, thus reduce your battery life (but not that much).
+
+	  Fast RR will make IrLAP send out a RR frame immediately when
+	  receiving a frame if its own transmit queue is currently empty. This
+	  will give a lot of speed improvement when receiving much data since
+	  the secondary station will not have to wait the max. turn around
+	  time (usually 500ms) before it is allowed to transmit the next time.
+	  If the transmit queue of the secondary is also empty, the primary will
+	  start backing-off before sending another RR frame, waiting longer
+	  each time until the back-off reaches the max. turn around time.
+	  This back-off increase in controlled via

+config IRDA_DEBUG
+	bool "Debug information"

+	help
+	  Say Y here if you want the IrDA subsystem to write debug information
+	  to your syslog. You can change the debug level in
+	  /proc/sys/net/irda/debug .
+	  When this option is enabled, the IrDA also perform many extra internal
+	  verifications which will usually prevent the kernel to crash in case of
+	  bugs.
+
+	  If unsure, say Y (since it makes it easier to find the bugs).

+ *     Linux-IrDA now supports four different types of IrDA sockets:
+ *
+ *     o SOCK_STREAM:    TinyTP connections with SAR disabled. The
+ *                       max SDU size is 0 for conn. of this type
+ *     o SOCK_SEQPACKET: TinyTP connections with SAR enabled. TTP may
+ *                       fragment the messages, but will preserve
+ *                       the message boundaries
+ *     o SOCK_DGRAM:     IRDAPROTO_UNITDATA: TinyTP connections with Unitdata
+ *                       (unreliable) transfers
+ *                       IRDAPROTO_ULTRA: Connectionless and unreliable data

+	help
+	  Say Y here if you want to build support for the IrLAN protocol.
+	  To compile it as a module, choose M here: the module will be called
+	  irlan.  IrLAN emulates an Ethernet and makes it possible to put up
+	  a wireless LAN using infrared beams.
+
+	  The IrLAN protocol can be used to talk with infrared access points
+	  like the HP NetbeamIR, or the ESI JetEye NET.  You can also connect
+	  to another Linux machine running the IrLAN protocol for ad-hoc
+	  networking!

+/************************** DOCUMENTATION ***************************/
+/*
+ * What is IrNET
+ * -------------
+ * IrNET is a protocol allowing to carry TCP/IP traffic between two
+ * IrDA peers in an efficient fashion. It is a thin layer, passing PPP
+ * packets to IrTTP and vice versa. It uses PPP in synchronous mode,
+ * because IrTTP offer a reliable sequenced packet service (as opposed
+ * to a byte stream). In fact, you could see IrNET as carrying TCP/IP
+ * in a IrDA socket, using PPP to provide the glue.
+ *
+ * The main difference with traditional PPP over IrCOMM is that we
+ * avoid the framing and serial emulation which are a performance
+ * bottleneck. It also allows multipoint communications in a sensible
+ * fashion.
+ *
+ * The main difference with IrLAN is that we use PPP for the link
+ * management, which is more standard, interoperable and flexible than
+ * the IrLAN protocol. For example, PPP adds authentication,
+ * encryption, compression, header compression and automated routing
+ * setup. And, as IrNET let PPP do the hard work, the implementation
+ * is much simpler than IrLAN.
+ *
+ * The Linux implementation
+ * ------------------------
+ * IrNET is written on top of the Linux-IrDA stack, and interface with
+ * the generic Linux PPP driver. Because IrNET depend on recent
+ * changes of the PPP driver interface, IrNET will work only with very
+ * recent kernel (2.3.99-pre6 and up).
+ *
+ * The present implementation offer the following features :
+ *	o simple user interface using pppd
+ *	o efficient implementation (interface directly to PPP and IrTTP)
+ *	o addressing (you can specify the name of the IrNET recipient)
+ *	o multipoint operation (limited by IrLAP specification)
+ *	o information in /proc/net/irda/irnet
+ *	o IrNET events on /dev/irnet (for user space daemon)
+ *	o IrNET daemon (irnetd) to automatically handle incoming requests
+ *	o Windows 2000 compatibility (tested, but need more work)
+ * Currently missing :
+ *	o Lot's of testing (that's your job)
+ *	o Connection retries (may be too hard to do)
+ *	o Check pppd persist mode
+ *	o User space daemon (to automatically handle incoming requests)
+ *
+ * The setup is not currently the most easy, but this should get much
+ * better when everything will get integrated...
+ *
+ * Acknowledgements
+ * ----------------
+ * This module is based on :
+ *	o The PPP driver (ppp_synctty/ppp_generic) by Paul Mackerras
+ *	o The IrLAN protocol (irlan_common/XXX) by Dag Brattli
+ *	o The IrSock interface (af_irda) by Dag Brattli
+ *	o Some other bits from the kernel and my drivers...
+ * Infinite thanks to those brave souls for providing the infrastructure
+ * upon which IrNET is built.
+ *
+ * Thanks to all my colleagues in HP for helping me. In particular,
+ * thanks to Salil Pradhan and Bill Serra for W2k testing...
+ * Thanks to Luiz Magalhaes for irnetd and much testing...
+ *
+ * Thanks to Alan Cox for answering lot's of my stupid questions, and
+ * to Paul Mackerras answering my questions on how to best integrate
+ * IrNET and pppd.
+ *
+ * Jean II
+ *
+ * Note on some implementations choices...
+ * ------------------------------------
+ *	1) Direct interface vs tty/socket
+ * I could have used a tty interface to hook to ppp and use the full
+ * socket API to connect to IrDA. The code would have been easier to
+ * maintain, and maybe the code would have been smaller...
+ * Instead, we hook directly to ppp_generic and to IrTTP, which make
+ * things more complicated...
+ *
+ * The first reason is flexibility : this allow us to create IrNET
+ * instances on demand (no /dev/ircommX crap) and to allow linkname
+ * specification on pppd command line...
+ *
+ * Second reason is speed optimisation. If you look closely at the
+ * transmit and receive paths, you will notice that they are "super lean"
+ * (that's why they look ugly), with no function calls and as little data
+ * copy and modification as I could...
+ *
+ *	2) irnetd in user space
+ * irnetd is implemented in user space, which is necessary to call pppd.
+ * This also give maximum benefits in term of flexibility and customability,
+ * and allow to offer the event channel, useful for other stuff like debug.
+ *
+ * On the other hand, this require a loose coordination between the
+ * present module and irnetd. One critical area is how incoming request
+ * are handled.
+ * When irnet receive an incoming request, it send an event to irnetd and
+ * drop the incoming IrNET socket.
+ * irnetd start a pppd instance, which create a new IrNET socket. This new
+ * socket is then connected in the originating node to the pppd instance.
+ * At this point, in the originating node, the first socket is closed.
+ *
+ * I admit, this is a bit messy and waste some resources. The alternative
+ * is caching incoming socket, and that's also quite messy and waste
+ * resources.
+ * We also make connection time slower. For example, on a 115 kb/s link it
+ * adds 60ms to the connection time (770 ms). However, this is slower than
+ * the time it takes to fire up pppd on my P133...
+ *
+ *
+ * History :
+ * -------
+ *
+ * v1 - 15.5.00 - Jean II
+ *	o Basic IrNET (hook to ppp_generic & IrTTP - incl. multipoint)
+ *	o control channel on /dev/irnet (set name/address)
+ *	o event channel on /dev/irnet (for user space daemon)
+ *
+ * v2 - 5.6.00 - Jean II
+ *	o Enable DROP_NOT_READY to avoid PPP timeouts & other weirdness...
+ *	o Add DISCONNECT_TO event and rename DISCONNECT_FROM.
+ *	o Set official device number alloaction on /dev/irnet
+ *
+ * v3 - 30.8.00 - Jean II
+ *	o Update to latest Linux-IrDA changes :
+ *		- queue_t => irda_queue_t
+ *	o Update to ppp-2.4.0 :
+ *		- move irda_irnet_connect from PPPIOCATTACH to TIOCSETD
+ *	o Add EXPIRE event (depend on new IrDA-Linux patch)
+ *	o Switch from `hashbin_remove' to `hashbin_remove_this' to fix
+ *	  a multilink bug... (depend on new IrDA-Linux patch)
+ *	o fix a self->daddr to self->raddr in irda_irnet_connect to fix
+ *	  another multilink bug (darn !)
+ *	o Remove LINKNAME_IOCTL cruft
+ *
+ * v3b - 31.8.00 - Jean II
+ *	o Dump discovery log at event channel startup
+ *
+ * v4 - 28.9.00 - Jean II
+ *	o Fix interaction between poll/select and dump discovery log
+ *	o Add IRNET_BLOCKED_LINK event (depend on new IrDA-Linux patch)
+ *	o Add IRNET_NOANSWER_FROM event (mostly to help support)
+ *	o Release flow control in disconnect_indication
+ *	o Block packets while connecting (speed up connections)
+ *
+ * v5 - 11.01.01 - Jean II
+ *	o Init self->max_header_size, just in case...
+ *	o Set up ap->chan.hdrlen, to get zero copy on tx side working.
+ *	o avoid tx->ttp->flow->ppp->tx->... loop, by checking flow state
+ *		Thanks to Christian Gennerat for finding this bug !
+ *	---
+ *	o Declare the proper MTU/MRU that we can support
+ *		(but PPP doesn't read the MTU value :-()
+ *	o Declare hashbin HB_NOLOCK instead of HB_LOCAL to avoid
+ *		disabling and enabling irq twice
+ *
+ * v6 - 31.05.01 - Jean II
+ *	o Print source address in Found, Discovery, Expiry & Request events
+ *	o Print requested source address in /proc/net/irnet
+ *	o Change control channel input. Allow multiple commands in one line.
+ *	o Add saddr command to change ap->rsaddr (and use that in IrDA)
+ *	---
+ *	o Make the IrDA connection procedure totally asynchronous.
+ *	  Heavy rewrite of the IAS query code and the whole connection
+ *	  procedure. Now, irnet_connect() no longer need to be called from
+ *	  a process context...
+ *	o Enable IrDA connect retries in ppp_irnet_send(). The good thing
+ *	  is that IrDA connect retries are directly driven by PPP LCP
+ *	  retries (we retry for each LCP packet), so that everything
+ *	  is transparently controlled from pppd lcp-max-configure.
+ *	o Add ttp_connect flag to prevent rentry on the connect procedure
+ *	o Test and fixups to eliminate side effects of retries
+ *
+ * v7 - 22.08.01 - Jean II
+ *	o Cleanup : Change "saddr = 0x0" to "saddr = DEV_ADDR_ANY"
+ *	o Fix bug in BLOCK_WHEN_CONNECT introduced in v6 : due to the
+ *	  asynchronous IAS query, self->tsap is NULL when PPP send the
+ *	  first packet.  This was preventing "connect-delay 0" to work.
+ *	  Change the test in ppp_irnet_send() to self->ttp_connect.
+ *
+ * v8 - 1.11.01 - Jean II
+ *	o Tighten the use of self->ttp_connect and self->ttp_open to
+ *	  prevent various race conditions.
+ *	o Avoid leaking discovery log and skb
+ *	o Replace "self" with "server" in irnet_connect_indication() to
+ *	  better detect cut'n'paste error ;-)
+ *
+ * v9 - 29.11.01 - Jean II
+ *	o Fix event generation in disconnect indication that I broke in v8
+ *	  It was always generation "No-Answer" because I was testing ttp_open
+ *	  just after clearing it. *blush*.
+ *	o Use newly created irttp_listen() to fix potential crash when LAP
+ *	  destroyed before irnet module removed.
+ *
+ * v10 - 4.3.2 - Jean II
+ *	o When receiving a disconnect indication, don't reenable the
+ *	  PPP Tx queue, this will trigger a reconnect. Instead, close
+ *	  the channel, which will kill pppd...
+ *
+ * v11 - 20.3.02 - Jean II
+ *	o Oops ! v10 fix disabled IrNET retries and passive behaviour.
+ *	  Better fix in irnet_disconnect_indication() :
+ *	  - if connected, kill pppd via hangup.
+ *	  - if not connected, reenable ppp Tx, which trigger IrNET retry.
+ *
+ * v12 - 10.4.02 - Jean II
+ *	o Fix race condition in irnet_connect_indication().
+ *	  If the socket was already trying to connect, drop old connection
+ *	  and use new one only if acting as primary. See comments.
+ *
+ * v13 - 30.5.02 - Jean II
+ *	o Update module init code
+ *
+ * v14 - 20.2.03 - Jean II
+ *	o Add discovery hint bits in the control channel.
+ *	o Remove obsolete MOD_INC/DEC_USE_COUNT in favor of .owner
+ *
+ * v15 - 7.4.03 - Jean II
+ *	o Replace spin_lock_irqsave() with spin_lock_bh() so that we can
+ *	  use ppp_unit_number(). It's probably also better overall...
+ *	o Disable call to ppp_unregister_channel(), because we can't do it.

+/*
+ * Notes on the concurrent access to hashbin and other SMP issues
+ * -------------------------------------------------------------
+ *	Hashbins are very often in the IrDA stack a global repository of
+ * information, and therefore used in a very asynchronous manner following
+ * various events (driver calls, timers, user calls...).
+ *	Therefore, very often it is highly important to consider the
+ * management of concurrent access to the hashbin and how to guarantee the
+ * consistency of the operations on it.
+ *
+ *	First, we need to define the objective of locking :
+ *		1) Protect user data (content pointed by the hashbin)
+ *		2) Protect hashbin structure itself (linked list in each bin)
+ *
+ *			     OLD LOCKING
+ *			     -----------
+ *
+ *	The previous locking strategy, either HB_LOCAL or HB_GLOBAL were
+ * both inadequate in *both* aspect.
+ *		o HB_GLOBAL was using a spinlock for each bin (local locking).
+ *		o HB_LOCAL was disabling irq on *all* CPUs, so use a single
+ *		  global semaphore.
+ *	The problems were :
+ *		A) Global irq disabling is no longer supported by the kernel
+ *		B) No protection for the hashbin struct global data
+ *			o hashbin_delete()
+ *			o hb_current
+ *		C) No protection for user data in some cases
+ *
+ *	A) HB_LOCAL use global irq disabling, so doesn't work on kernel
+ * 2.5.X. Even when it is supported (kernel 2.4.X and earlier), its
+ * performance is not satisfactory on SMP setups. Most hashbins were
+ * HB_LOCAL, so (A) definitely need fixing.
+ *	B) HB_LOCAL could be modified to fix (B). However, because HB_GLOBAL
+ * lock only the individual bins, it will never be able to lock the
+ * global data, so can't do (B).
+ *	C) Some functions return pointer to data that is still in the
+ * hashbin :
+ *		o hashbin_find()
+ *		o hashbin_get_first()
+ *		o hashbin_get_next()
+ *	As the data is still in the hashbin, it may be changed or free'd
+ * while the caller is examinimg the data. In those case, locking can't
+ * be done within the hashbin, but must include use of the data within
+ * the caller.
+ *	The caller can easily do this with HB_LOCAL (just disable irqs).
+ * However, this is impossible with HB_GLOBAL because the caller has no
+ * way to know the proper bin, so don't know which spinlock to use.
+ *
+ *	Quick summary : can no longer use HB_LOCAL, and HB_GLOBAL is
+ * fundamentally broken and will never work.
+ *
+ *			     NEW LOCKING
+ *			     -----------
+ *
+ *	To fix those problems, I've introduce a few changes in the
+ * hashbin locking :
+ *		1) New HB_LOCK scheme
+ *		2) hashbin->hb_spinlock
+ *		3) New hashbin usage policy
+ *
+ * HB_LOCK :
+ * -------
+ *	HB_LOCK is a locking scheme intermediate between the old HB_LOCAL
+ * and HB_GLOBAL. It uses a single spinlock to protect the whole content
+ * of the hashbin. As it is a single spinlock, it can protect the global
+ * data of the hashbin and not only the bins themselves.
+ *	HB_LOCK can only protect some of the hashbin calls, so it only lock
+ * call that can be made 100% safe and leave other call unprotected.
+ *	HB_LOCK in theory is slower than HB_GLOBAL, but as the hashbin
+ * content is always small contention is not high, so it doesn't matter
+ * much. HB_LOCK is probably faster than HB_LOCAL.
+ *
+ * hashbin->hb_spinlock :
+ * --------------------
+ *	The spinlock that HB_LOCK uses is available for caller, so that
+ * the caller can protect unprotected calls (see below).
+ *	If the caller want to do entirely its own locking (HB_NOLOCK), he
+ * can do so and may use safely this spinlock.
+ *	Locking is done like this :
+ *		spin_lock_irqsave(&hashbin->hb_spinlock, flags);
+ *	Releasing the lock :
+ *		spin_unlock_irqrestore(&hashbin->hb_spinlock, flags);
+ *
+ * Safe & Protected calls :
+ * ----------------------
+ *	The following calls are safe or protected via HB_LOCK :
+ *		o hashbin_new()		-> safe
+ *		o hashbin_delete()
+ *		o hashbin_insert()
+ *		o hashbin_remove_first()
+ *		o hashbin_remove()
+ *		o hashbin_remove_this()
+ *		o HASHBIN_GET_SIZE()	-> atomic
+ *
+ *	The following calls only protect the hashbin itself :
+ *		o hashbin_lock_find()
+ *		o hashbin_find_next()
+ *
+ * Unprotected calls :
+ * -----------------
+ *	The following calls need to be protected by the caller :
+ *		o hashbin_find()
+ *		o hashbin_get_first()
+ *		o hashbin_get_next()
+ *
+ * Locking Policy :
+ * --------------
+ *	If the hashbin is used only in a single thread of execution
+ * (explicitly or implicitely), you can use HB_NOLOCK
+ *	If the calling module already provide concurrent access protection,
+ * you may use HB_NOLOCK.
+ *
+ *	In all other cases, you need to use HB_LOCK and lock the hashbin
+ * every time before calling one of the unprotected calls. You also must
+ * use the pointer returned by the unprotected call within the locked
+ * region.
+ *
+ * Extra care for enumeration :
+ * --------------------------
+ *	hashbin_get_first() and hashbin_get_next() use the hashbin to
+ * store the current position, in hb_current.
+ *	As long as the hashbin remains locked, this is safe. If you unlock
+ * the hashbin, the current position may change if anybody else modify
+ * or enumerate the hashbin.
+ *	Summary : do the full enumeration while locked.
+ *
+ *	Alternatively, you may use hashbin_find_next(). But, this will
+ * be slower, is more complex to use and doesn't protect the hashbin
+ * content. So, care is needed here as well.
+ *
+ * Other issues :
+ * ------------
+ *	I believe that we are overdoing it by using spin_lock_irqsave()
+ * and we should use only spin_lock_bh() or similar. But, I don't have
+ * the balls to try it out.
+ *	Don't believe that because hashbin are now (somewhat) SMP safe
+ * that the rest of the code is. Higher layers tend to be safest,
+ * but LAP and LMP would need some serious dedicated love.

-	  The Infrared Data Associations (tm) specifies standards for wireless

-
-	  To use Linux support for the IrDA (tm) protocols, you will also need

-
-	  If you want to exchange bits of data (vCal, vCard) with a PDA, you

-	depends on IRDA
-	---help---
-	  Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
-	  when acting as a primary station.
-	  Disabling this option will make latency over IrDA very bad. Enabling
-	  this option will make the IrDA stack send more packet than strictly
-	  necessary, thus reduce your battery life (but not that much).
-
-	  Fast RR will make IrLAP send out a RR frame immediately when
-	  receiving a frame if its own transmit queue is currently empty. This
-	  will give a lot of speed improvement when receiving much data since
-	  the secondary station will not have to wait the max. turn around
-	  time (usually 500ms) before it is allowed to transmit the next time.
-	  If the transmit queue of the secondary is also empty, the primary will
-	  start backing-off before sending another RR frame, waiting longer
-	  each time until the back-off reaches the max. turn around time.

-	  When this option is enabled, the IrDA also perform many extra internal
-	  verifications which will usually prevent the kernel to crash in case of
-	  bugs.
-

-/*
- * What is IrNET
- * -------------
- * IrNET is a protocol allowing to carry TCP/IP traffic between two
- * IrDA peers in an efficient fashion. It is a thin layer, passing PPP
- * packets to IrTTP and vice versa. It uses PPP in synchronous mode,
- * because IrTTP offer a reliable sequenced packet service (as opposed
- * to a byte stream). In fact, you could see IrNET as carrying TCP/IP
- * in a IrDA socket, using PPP to provide the glue.
- *
- * The main difference with traditional PPP over IrCOMM is that we
- * avoid the framing and serial emulation which are a performance
- * bottleneck. It also allows multipoint communications in a sensible
- * fashion.
- *
- * The main difference with IrLAN is that we use PPP for the link
- * management, which is more standard, interoperable and flexible than
- * the IrLAN protocol. For example, PPP adds authentication,
- * encryption, compression, header compression and automated routing
- * setup. And, as IrNET let PPP do the hard work, the implementation
- * is much simpler than IrLAN.
- *
- * The Linux implementation
- * ------------------------
- * IrNET is written on top of the Linux-IrDA stack, and interface with
- * the generic Linux PPP driver. Because IrNET depend on recent
- * changes of the PPP driver interface, IrNET will work only with very
- * recent kernel (2.3.99-pre6 and up).
- *
- * The present implementation offer the following features :
- *	o simple user interface using pppd
- *	o efficient implementation (interface directly to PPP and IrTTP)
- *	o addressing (you can specify the name of the IrNET recipient)
- *	o multipoint operation (limited by IrLAP specification)
- *	o information in /proc/net/irda/irnet
- *	o IrNET events on /dev/irnet (for user space daemon)
- *	o IrNET daemon (irnetd) to automatically handle incoming requests
- *	o Windows 2000 compatibility (tested, but need more work)
- * Currently missing :
- *	o Lot's of testing (that's your job)
- *	o Connection retries (may be too hard to do)
- *	o Check pppd persist mode
- *	o User space daemon (to automatically handle incoming requests)
- *
- * The setup is not currently the most easy, but this should get much
- * better when everything will get integrated...
- *
- * Acknowledgements
- * ----------------
- * This module is based on :
- *	o The PPP driver (ppp_synctty/ppp_generic) by Paul Mackerras
- *	o The IrLAN protocol (irlan_common/XXX) by Dag Brattli
- *	o The IrSock interface (af_irda) by Dag Brattli
- *	o Some other bits from the kernel and my drivers...
- * Infinite thanks to those brave souls for providing the infrastructure
- * upon which IrNET is built.
- *
- * Thanks to all my colleagues in HP for helping me. In particular,
- * thanks to Salil Pradhan and Bill Serra for W2k testing...
- * Thanks to Luiz Magalhaes for irnetd and much testing...
- *
- * Thanks to Alan Cox for answering lot's of my stupid questions, and
- * to Paul Mackerras answering my questions on how to best integrate
- * IrNET and pppd.
- *
- * Jean II
- *
- * Note on some implementations choices...
- * ------------------------------------
- *	1) Direct interface vs tty/socket
- * I could have used a tty interface to hook to ppp and use the full
- * socket API to connect to IrDA. The code would have been easier to
- * maintain, and maybe the code would have been smaller...
- * Instead, we hook directly to ppp_generic and to IrTTP, which make
- * things more complicated...
- *
- * The first reason is flexibility : this allow us to create IrNET
- * instances on demand (no /dev/ircommX crap) and to allow linkname
- * specification on pppd command line...
- *
- * Second reason is speed optimisation. If you look closely at the
- * transmit and receive paths, you will notice that they are "super lean"
- * (that's why they look ugly), with no function calls and as little data
- * copy and modification as I could...
- *
- *	2) irnetd in user space
- * irnetd is implemented in user space, which is necessary to call pppd.
- * This also give maximum benefits in term of flexibility and customability,
- * and allow to offer the event channel, useful for other stuff like debug.
- *
- * On the other hand, this require a loose coordination between the
- * present module and irnetd. One critical area is how incoming request
- * are handled.
- * When irnet receive an incoming request, it send an event to irnetd and
- * drop the incoming IrNET socket.
- * irnetd start a pppd instance, which create a new IrNET socket. This new
- * socket is then connected in the originating node to the pppd instance.
- * At this point, in the originating node, the first socket is closed.
- *
- * I admit, this is a bit messy and waste some resources. The alternative
- * is caching incoming socket, and that's also quite messy and waste
- * resources.
- * We also make connection time slower. For example, on a 115 kb/s link it
- * adds 60ms to the connection time (770 ms). However, this is slower than
- * the time it takes to fire up pppd on my P133...
- *
- *
- * History :
- * -------
- *
- * v1 - 15.5.00 - Jean II
- *	o Basic IrNET (hook to ppp_generic & IrTTP - incl. multipoint)
- *	o control channel on /dev/irnet (set name/address)
- *	o event channel on /dev/irnet (for user space daemon)
- *
- * v2 - 5.6.00 - Jean II
- *	o Enable DROP_NOT_READY to avoid PPP timeouts & other weirdness...
- *	o Add DISCONNECT_TO event and rename DISCONNECT_FROM.
- *	o Set official device number alloaction on /dev/irnet
- *
- * v3 - 30.8.00 - Jean II
- *	o Update to latest Linux-IrDA changes :
- *		- queue_t => irda_queue_t
- *	o Update to ppp-2.4.0 :
- *		- move irda_irnet_connect from PPPIOCATTACH to TIOCSETD
- *	o Add EXPIRE event (depend on new IrDA-Linux patch)
- *	o Switch from `hashbin_remove' to `hashbin_remove_this' to fix
- *	  a multilink bug... (depend on new IrDA-Linux patch)
- *	o fix a self->daddr to self->raddr in irda_irnet_connect to fix
- *	  another multilink bug (darn !)
- *	o Remove LINKNAME_IOCTL cruft
- *
- * v3b - 31.8.00 - Jean II
- *	o Dump discovery log at event channel startup
- *
- * v4 - 28.9.00 - Jean II
- *	o Fix interaction between poll/select and dump discovery log
- *	o Add IRNET_BLOCKED_LINK event (depend on new IrDA-Linux patch)
- *	o Add IRNET_NOANSWER_FROM event (mostly to help support)
- *	o Release flow control in disconnect_indication
- *	o Block packets while connecting (speed up connections)
- *
- * v5 - 11.01.01 - Jean II
- *	o Init self->max_header_size, just in case...
- *	o Set up ap->chan.hdrlen, to get zero copy on tx side working.
- *	o avoid tx->ttp->flow->ppp->tx->... loop, by checking flow state
- *		Thanks to Christian Gennerat for finding this bug !
- *	---
- *	o Declare the proper MTU/MRU that we can support
- *		(but PPP doesn't read the MTU value :-()
- *	o Declare hashbin HB_NOLOCK instead of HB_LOCAL to avoid
- *		disabling and enabling irq twice
- *
- * v6 - 31.05.01 - Jean II
- *	o Print source address in Found, Discovery, Expiry & Request events
- *	o Print requested source address in /proc/net/irnet
- *	o Change control channel input. Allow multiple commands in one line.
- *	o Add saddr command to change ap->rsaddr (and use that in IrDA)
- *	---
- *	o Make the IrDA connection procedure totally asynchronous.
- *	  Heavy rewrite of the IAS query code and the whole connection
- *	  procedure. Now, irnet_connect() no longer need to be called from
- *	  a process context...
- *	o Enable IrDA connect retries in ppp_irnet_send(). The good thing
- *	  is that IrDA connect retries are directly driven by PPP LCP
- *	  retries (we retry for each LCP packet), so that everything
- *	  is transparently controlled from pppd lcp-max-configure.
- *	o Add ttp_connect flag to prevent rentry on the connect procedure
- *	o Test and fixups to eliminate side effects of retries
- *
- * v7 - 22.08.01 - Jean II
- *	o Cleanup : Change "saddr = 0x0" to "saddr = DEV_ADDR_ANY"
- *	o Fix bug in BLOCK_WHEN_CONNECT introduced in v6 : due to the
- *	  asynchronous IAS query, self->tsap is NULL when PPP send the
- *	  first packet.  This was preventing "connect-delay 0" to work.
- *	  Change the test in ppp_irnet_send() to self->ttp_connect.
- *
- * v8 - 1.11.01 - Jean II
- *	o Tighten the use of self->ttp_connect and self->ttp_open to
- *	  prevent various race conditions.
- *	o Avoid leaking discovery log and skb
- *	o Replace "self" with "server" in irnet_connect_indication() to
- *	  better detect cut'n'paste error ;-)
- *
- * v9 - 29.11.01 - Jean II
- *	o Fix event generation in disconnect indication that I broke in v8
- *	  It was always generation "No-Answer" because I was testing ttp_open
- *	  just after clearing it. *blush*.
- *	o Use newly created irttp_listen() to fix potential crash when LAP
- *	  destroyed before irnet module removed.
- *
- * v10 - 4.3.2 - Jean II
- *	o When receiving a disconnect indication, don't reenable the
- *	  PPP Tx queue, this will trigger a reconnect. Instead, close
- *	  the channel, which will kill pppd...
- *
- * v11 - 20.3.02 - Jean II
- *	o Oops ! v10 fix disabled IrNET retries and passive behaviour.
- *	  Better fix in irnet_disconnect_indication() :
- *	  - if connected, kill pppd via hangup.
- *	  - if not connected, reenable ppp Tx, which trigger IrNET retry.
- *
- * v12 - 10.4.02 - Jean II
- *	o Fix race condition in irnet_connect_indication().
- *	  If the socket was already trying to connect, drop old connection
- *	  and use new one only if acting as primary. See comments.
- *
- * v13 - 30.5.02 - Jean II
- *	o Update module init code
- *
- * v14 - 20.2.03 - Jean II
- *	o Add discovery hint bits in the control channel.
- *	o Remove obsolete MOD_INC/DEC_USE_COUNT in favor of .owner
- *
- * v15 - 7.4.03 - Jean II
- *	o Replace spin_lock_irqsave() with spin_lock_bh() so that we can
- *	  use ppp_unit_number(). It's probably also better overall...
- *	o Disable call to ppp_unregister_channel(), because we can't do it.

-/*
- * Notes on the concurrent access to hashbin and other SMP issues
- * -------------------------------------------------------------
- *	Hashbins are very often in the IrDA stack a global repository of
- * information, and therefore used in a very asynchronous manner following
- * various events (driver calls, timers, user calls...).
- *	Therefore, very often it is highly important to consider the
- * management of concurrent access to the hashbin and how to guarantee the
- * consistency of the operations on it.
- *
- *	First, we need to define the objective of locking :
- *		1) Protect user data (content pointed by the hashbin)
- *		2) Protect hashbin structure itself (linked list in each bin)
- *
- *			     OLD LOCKING
- *			     -----------
- *
- *	The previous locking strategy, either HB_LOCAL or HB_GLOBAL were
- * both inadequate in *both* aspect.
- *		o HB_GLOBAL was using a spinlock for each bin (local locking).
- *		o HB_LOCAL was disabling irq on *all* CPUs, so use a single
- *		  global semaphore.
- *	The problems were :
- *		A) Global irq disabling is no longer supported by the kernel
- *		B) No protection for the hashbin struct global data
- *			o hashbin_delete()
- *			o hb_current
- *		C) No protection for user data in some cases
- *
- *	A) HB_LOCAL use global irq disabling, so doesn't work on kernel
- * 2.5.X. Even when it is supported (kernel 2.4.X and earlier), its
- * performance is not satisfactory on SMP setups. Most hashbins were
- * HB_LOCAL, so (A) definitely need fixing.
- *	B) HB_LOCAL could be modified to fix (B). However, because HB_GLOBAL
- * lock only the individual bins, it will never be able to lock the
- * global data, so can't do (B).
- *	C) Some functions return pointer to data that is still in the
- * hashbin :
- *		o hashbin_find()
- *		o hashbin_get_first()
- *		o hashbin_get_next()
- *	As the data is still in the hashbin, it may be changed or free'd
- * while the caller is examinimg the data. In those case, locking can't
- * be done within the hashbin, but must include use of the data within
- * the caller.
- *	The caller can easily do this with HB_LOCAL (just disable irqs).
- * However, this is impossible with HB_GLOBAL because the caller has no
- * way to know the proper bin, so don't know which spinlock to use.
- *
- *	Quick summary : can no longer use HB_LOCAL, and HB_GLOBAL is
- * fundamentally broken and will never work.
- *
- *			     NEW LOCKING
- *			     -----------
- *
- *	To fix those problems, I've introduce a few changes in the
- * hashbin locking :
- *		1) New HB_LOCK scheme
- *		2) hashbin->hb_spinlock
- *		3) New hashbin usage policy
- *
- * HB_LOCK :
- * -------
- *	HB_LOCK is a locking scheme intermediate between the old HB_LOCAL
- * and HB_GLOBAL. It uses a single spinlock to protect the whole content
- * of the hashbin. As it is a single spinlock, it can protect the global
- * data of the hashbin and not only the bins themselves.
- *	HB_LOCK can only protect some of the hashbin calls, so it only lock
- * call that can be made 100% safe and leave other call unprotected.
- *	HB_LOCK in theory is slower than HB_GLOBAL, but as the hashbin
- * content is always small contention is not high, so it doesn't matter
- * much. HB_LOCK is probably faster than HB_LOCAL.
- *
- * hashbin->hb_spinlock :
- * --------------------
- *	The spinlock that HB_LOCK uses is available for caller, so that
- * the caller can protect unprotected calls (see below).
- *	If the caller want to do entirely its own locking (HB_NOLOCK), he
- * can do so and may use safely this spinlock.
- *	Locking is done like this :
- *		spin_lock_irqsave(&hashbin->hb_spinlock, flags);
- *	Releasing the lock :
- *		spin_unlock_irqrestore(&hashbin->hb_spinlock, flags);
- *
- * Safe & Protected calls :
- * ----------------------
- *	The following calls are safe or protected via HB_LOCK :
- *		o hashbin_new()		-> safe
- *		o hashbin_delete()
- *		o hashbin_insert()
- *		o hashbin_remove_first()
- *		o hashbin_remove()
- *		o hashbin_remove_this()
- *		o HASHBIN_GET_SIZE()	-> atomic
- *
- *	The following calls only protect the hashbin itself :
- *		o hashbin_lock_find()
- *		o hashbin_find_next()
- *
- * Unprotected calls :
- * -----------------
- *	The following calls need to be protected by the caller :
- *		o hashbin_find()
- *		o hashbin_get_first()
- *		o hashbin_get_next()
- *
- * Locking Policy :
- * --------------
- *	If the hashbin is used only in a single thread of execution
- * (explicitly or implicitely), you can use HB_NOLOCK
- *	If the calling module already provide concurrent access protection,
- * you may use HB_NOLOCK.
- *
- *	In all other cases, you need to use HB_LOCK and lock the hashbin
- * every time before calling one of the unprotected calls. You also must
- * use the pointer returned by the unprotected call within the locked
- * region.
- *
- * Extra care for enumeration :
- * --------------------------
- *	hashbin_get_first() and hashbin_get_next() use the hashbin to
- * store the current position, in hb_current.
- *	As long as the hashbin remains locked, this is safe. If you unlock
- * the hashbin, the current position may change if anybody else modify
- * or enumerate the hashbin.
- *	Summary : do the full enumeration while locked.
- *
- *	Alternatively, you may use hashbin_find_next(). But, this will
- * be slower, is more complex to use and doesn't protect the hashbin
- * content. So, care is needed here as well.
- *
- * Other issues :
- * ------------
- *	I believe that we are overdoing it by using spin_lock_irqsave()
- * and we should use only spin_lock_bh() or similar. But, I don't have
- * the balls to try it out.
- *	Don't believe that because hashbin are now (somewhat) SMP safe
- * that the rest of the code is. Higher layers tend to be safest,
- * but LAP and LMP would need some serious dedicated love.

- *			    IMPORTANT NOTE
- *			    --------------
- *
- * As of kernel 2.5.20, this is the state of compliance and testing of
- * this driver (irda-usb) with regards to the USB low level drivers...
- *
- * This driver has been tested SUCCESSFULLY with the following drivers :
- *	o usb-uhci-hcd	(For Intel/Via USB controllers)
- *	o uhci-hcd	(Alternate/JE driver for Intel/Via USB controllers)
- *	o ohci-hcd	(For other USB controllers)
- *
- * This driver has NOT been tested with the following drivers :
- *	o ehci-hcd	(USB 2.0 controllers)
- *
- * Note that all HCD drivers do URB_ZERO_PACKET and timeout properly,
- * so we don't have to worry about that anymore.
- * One common problem is the failure to set the address on the dongle,
- * but this happens before the driver gets loaded...
- *
- * Jean II

-/*
- * This is my current (2007-04-25) understanding of how this dongle is supposed
- * to work. This is based on reverse-engineering and examination of the packet
- * data sent and received by the WinXP driver using USBSnoopy. Feel free to
- * update here as more of this dongle is known:
- *
- * General: Unlike the other USB IrDA dongles, this particular dongle exposes,
- * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
- * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
- * order to receive data.
- * Transmission: Just like stir4200, this dongle uses a raw stream of data,
- * which needs to be wrapped and escaped in a similar way as in stir4200.c.
- * Reception: Poll-based, as in stir4200. Each read returns the contents of a
- * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
- * (1-7) of valid data contained within the remaining 7 bytes. For example, if
- * the buffer had the following contents:
- *  06 ff ff ff c0 01 04 aa
- * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
- * end is garbage (left over from a previous reception) and is discarded.
- * If a read returns an "impossible" value as the length of valid data (such as
- * 0x36) in the first byte, then the buffer is uninitialized (as is the case of
- * first plug-in) and its contents should be discarded. There is currently no
- * evidence that the top 5 bits of the 1st byte of the buffer can have values
- * other than 0 once reception begins.
- * Once valid bytes are collected, the assembled stream is a sequence of
- * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
- * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
- * a successful read from the host, which means that in absence of further
- * reception, repeated reads from the dongle will return the exact same
- * contents repeatedly. Attempts to be smart and cache a previous read seem
- * to result in corrupted packets, so this driver depends on the unwrap logic
- * to sort out any repeated reads.
- * Speed change: no commands observed so far to change speed, assumed fixed
- * 9600bps (SIR).

-/*
- * Following is my most current (2007-07-17) understanding of how the Kingsun
- * KS-959 dongle is supposed to work. This information was deduced by
- * reverse-engineering and examining the USB traffic captured with USBSnoopy
- * from the WinXP driver. Feel free to update here as more of the dongle is
- * known.
- *
- * My most sincere thanks must go to Domen Puncer <domen@coderock.org> for
- * invaluable help in cracking the obfuscation and padding required for this
- * dongle.
- *
- * General: This dongle exposes one interface with one interrupt IN endpoint.
- * However, the interrupt endpoint is NOT used at all for this dongle. Instead,
- * this dongle uses control transfers for everything, including sending and
- * receiving the IrDA frame data. Apparently the interrupt endpoint is just a
- * dummy to ensure the dongle has a valid interface to present to the PC.And I
- * thought the DonShine dongle was weird... In addition, this dongle uses
- * obfuscation (?!?!), applied at the USB level, to hide the traffic, both sent
- * and received, from the dongle. I call it obfuscation because the XOR keying
- * and padding required to produce an USB traffic acceptable for the dongle can
- * not be explained by any other technical requirement.
- *
- * Transmission: To transmit an IrDA frame, the driver must prepare a control
- * URB with the following as a setup packet:
- *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x09
- *    wValue          <length of valid data before padding, little endian>
- *    wIndex          0x0000
- *    wLength         <length of padded data>
- * The payload packet must be manually wrapped and escaped (as in stir4200.c),
- * then padded and obfuscated before being sent. Both padding and obfuscation
- * are implemented in the procedure obfuscate_tx_buffer(). Suffice to say, the
- * designer/programmer of the dongle used his name as a source for the
- * obfuscation. WTF?!
- * Apparently the dongle cannot handle payloads larger than 256 bytes. The
- * driver has to perform fragmentation in order to send anything larger than
- * this limit.
- *
- * Reception: To receive data, the driver must poll the dongle regularly (like
- * kingsun-sir.c) with control URBs and the following as a setup packet:
- *    bRequestType    USB_DIR_IN | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x01
- *    wValue          0x0200
- *    wIndex          0x0000
- *    wLength         0x0800 (size of available buffer)
- * If there is data to be read, it will be returned as the response payload.
- * This data is (apparently) not padded, but it is obfuscated. To de-obfuscate
- * it, the driver must XOR every byte, in sequence, with a value that starts at
- * 1 and is incremented with each byte processed, and then with 0x55. The value
- * incremented with each byte processed overflows as an unsigned char. The
- * resulting bytes form a wrapped SIR frame that is unwrapped and unescaped
- * as in stir4200.c The incremented value is NOT reset with each frame, but is
- * kept across the entire session with the dongle. Also, the dongle inserts an
- * extra garbage byte with value 0x95 (after decoding) every 0xff bytes, which
- * must be skipped.
- *
- * Speed change: To change the speed of the dongle, the driver prepares a
- * control URB with the following as a setup packet:
- *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x09
- *    wValue          0x0200
- *    wIndex          0x0001
- *    wLength         0x0008 (length of the payload)
- * The payload is a 8-byte record, apparently identical to the one used in
- * drivers/usb/serial/cypress_m8.c to change speed:
- *     __u32 baudSpeed;
- *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
- *    unsigned int : 1;
- *    unsigned int stopBits : 1;
- *    unsigned int parityEnable : 1;
- *    unsigned int parityType : 1;
- *    unsigned int : 1;
- *    unsigned int reset : 1;
- *    unsigned char reserved[3];    // set to 0
- *
- * For now only SIR speeds have been observed with this dongle. Therefore,
- * nothing is known on what changes (if any) must be done to frame wrapping /
- * unwrapping for higher than SIR speeds. This driver assumes no change is
- * necessary and announces support for all the way to 57600 bps. Although the
- * package announces support for up to 4MBps, tests with a Sony Ericcson K300
- * phone show corruption when receiving large frames at 115200 bps, the highest
- * speed announced by the phone. However, transmission at 115200 bps is OK. Go
- * figure. Since I don't know whether the phone or the dongle is at fault, max
- * announced speed is 57600 bps until someone produces a device that can run
- * at higher speeds with this dongle.

-/*
- * Following is my most current (2007-07-26) understanding of how the Kingsun
- * 07D0:4100 dongle (sometimes known as the MA-660) is supposed to work. This
- * information was deduced by examining the USB traffic captured with USBSnoopy
- * from the WinXP driver. Feel free to update here as more of the dongle is
- * known.
- *
- * General: This dongle exposes one interface with two interrupt endpoints, one
- * IN and one OUT. In this regard, it is similar to what the Kingsun/Donshine
- * dongle (07c0:4200) exposes. Traffic is raw and needs to be wrapped and
- * unwrapped manually as in stir4200, kingsun-sir, and ks959-sir.
- *
- * Transmission: To transmit an IrDA frame, it is necessary to wrap it, then
- * split it into multiple segments of up to 7 bytes each, and transmit each in
- * sequence. It seems that sending a single big block (like kingsun-sir does)
- * won't work with this dongle. Each segment needs to be prefixed with a value
- * equal to (unsigned char)0xF8 + <number of bytes in segment>, inside a payload
- * of exactly 8 bytes. For example, a segment of 1 byte gets prefixed by 0xF9,
- * and one of 7 bytes gets prefixed by 0xFF. The bytes at the end of the
- * payload, not considered by the prefix, are ignored (set to 0 by this
- * implementation).
- *
- * Reception: To receive data, the driver must poll the dongle regularly (like
- * kingsun-sir.c) with interrupt URBs. If data is available, it will be returned
- * in payloads from 0 to 8 bytes long. When concatenated, these payloads form
- * a raw IrDA stream that needs to be unwrapped as in stir4200 and kingsun-sir
- *
- * Speed change: To change the speed of the dongle, the driver prepares a
- * control URB with the following as a setup packet:
- *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x09
- *    wValue          0x0200
- *    wIndex          0x0001
- *    wLength         0x0008 (length of the payload)
- * The payload is a 8-byte record, apparently identical to the one used in
- * drivers/usb/serial/cypress_m8.c to change speed:
- *     __u32 baudSpeed;
- *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
- *    unsigned int : 1;
- *    unsigned int stopBits : 1;
- *    unsigned int parityEnable : 1;
- *    unsigned int parityType : 1;
- *    unsigned int : 1;
- *    unsigned int reset : 1;
- *    unsigned char reserved[3];    // set to 0
- *
- * For now only SIR speeds have been observed with this dongle. Therefore,
- * nothing is known on what changes (if any) must be done to frame wrapping /
- * unwrapping for higher than SIR speeds. This driver assumes no change is
- * necessary and announces support for all the way to 115200 bps.

- * Belkin is selling a dongle called the SmartBeam.
- * In fact, there is two hardware version of this dongle, of course with
- * the same name and looking the exactly same (grrr...).
- * I guess that I've got the old one, because inside I don't have
- * a jumper for IrDA/ASK...
- *
- * As far as I can make it from info on their web site, the old dongle 
- * support only 9600 b/s, which make our life much simpler as far as
- * the driver is concerned, but you might not like it very much ;-)
- * The new SmartBeam does 115 kb/s, and I've not tested it...
- *
- * Belkin claim that the correct driver for the old dongle (in Windows)
- * is the generic Parallax 9500a driver, but the Linux LiteLink driver
- * fails for me (probably because Linux-IrDA doesn't rate fallback),
- * so I created this really dumb driver...
- *
- * In fact, this driver doesn't do much. The only thing it does is to
- * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
- * driver is called "old_belkin" so that when the new SmartBeam is supported
- * its driver can be called "belkin" instead of "new_belkin".
- *
- * Note : this driver was written without any info/help from Belkin,
- * so a lot of info here might be totally wrong. Blame me ;-)

- ********************************************************************/
-
-/*
- * This driver has currently only been tested on the IRWave IR320ST-2
- *
- * PROTOCOL:
- *
- * The protocol for talking to the TOIM3232 is quite easy, and is
- * designed to interface with RS232 with only level convertors. The
- * BR/~D line on the chip is brought high to signal 'command mode',
- * where a command byte is sent to select the baudrate of the RS232
- * interface and the pulse length of the IRDA output. When BR/~D
- * is brought low, the dongle then changes to the selected baudrate,
- * and the RS232 interface is used for data until BR/~D is brought
- * high again. The initial speed for the TOIMx323 after RESET is
- * 9600 baud.  The baudrate for command-mode is the last selected
- * baud-rate, or 9600 after a RESET.
- *
- * The  dongle I have (below) adds some extra hardware on the front end,
- * but this is mostly directed towards pariasitic power from the RS232
- * line rather than changing very much about how to communicate with
- * the TOIM3232.
- *
- * The protocol to talk to the TOIM4232 chipset seems to be almost
- * identical to the TOIM3232 (and the 4232 datasheet is more detailed)
- * so this code will probably work on that as well, although I haven't
- * tested it on that hardware.
- *
- * Target dongle variations that might be common:
- *
- * DTR and RTS function:
- *   The data sheet for the 4232 has a sample implementation that hooks the
- *   DTR and RTS lines to the RESET and BaudRate/~Data lines of the
- *   chip (through line-converters). Given both DTR and RTS would have to
- *   be held low in normal operation, and the TOIMx232 requires +5V to
- *   signal ground, most dongle designers would almost certainly choose
- *   an implementation that kept at least one of DTR or RTS high in
- *   normal operation to provide power to the dongle, but will likely
- *   vary between designs.
- *
- * User specified command bits:
- *  There are two user-controllable output lines from the TOIMx232 that
- *  can be set low or high by setting the appropriate bits in the
- *  high-nibble of the command byte (when setting speed and pulse length).
- *  These might be used to switch on and off added hardware or extra
- *  dongle features.
- *
- *
- * Target hardware: IRWave IR320ST-2
- *
- * 	The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
- * 	TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transceiver.
- * 	It uses a hex inverter and some discrete components to buffer and
- * 	line convert the RS232 down to 5V.
- *
- * 	The dongle is powered through a voltage regulator, fed by a large
- * 	capacitor. To switch the dongle on, DTR is brought high to charge
- * 	the capacitor and drive the voltage regulator. DTR isn't associated
- * 	with any control lines on the TOIM3232. Parisitic power is also taken
- * 	from the RTS, TD and RD lines when brought high, but through resistors.
- * 	When DTR is low, the circuit might lose power even with RTS high.
- *
- * 	RTS is inverted and attached to the BR/~D input pin. When RTS
- * 	is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
- * 	RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
- * 	mode'.
- *
- * 	For some unknown reason, the RESET line isn't actually connected
- * 	to anything. This means to reset the dongle to get it to a known
- * 	state (9600 baud) you must drop DTR and RTS low, wait for the power
- * 	capacitor to discharge, and then bring DTR (and RTS for data mode)
- * 	high again, and wait for the capacitor to charge, the power supply
- * 	to stabilise, and the oscillator clock to stabilise.
- *
- * 	Fortunately, if the current baudrate is known, the chipset can
- * 	easily change speed by entering command mode without having to
- * 	reset the dongle first.
- *
- * 	Major Components:
- *
- * 	- Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings
- * 	  to IRDA pulse timings
- * 	- 3.6864MHz crystal to drive TOIM3232 clock oscillator
- * 	- DM74lS04M Inverting Hex line buffer for RS232 input buffering
- * 	  and level conversion
- * 	- PJ2951AC 150mA voltage regulator
- * 	- Vishay/Temic TFDS4500	SIR IRDA front-end transceiver
- *

- * What we should do is:
- * 	0. Pull RESET high
- * 	1. Wait for at least 7us
- * 	2. Pull RESET low
- * 	3. Wait for at least 7us
- * 	4. Pull BR/~D high

- * 	6. Send control byte to set baud rate
- * 	7. Wait at least 1us after stop bit
- * 	8. Pull BR/~D low
- * 	9. Should then be in data mode
- *
- * Because the IR320ST-2 doesn't have the RESET line connected for some reason,
- * we'll have to do something else.
- *
- * The default speed after a RESET is 9600, so lets try just bringing it up in
- * data mode after switching it off, waiting for the supply capacitor to
- * discharge, and then switch it back on. This isn't actually pulling RESET
- * high, but it seems to have the same effect.
- *
- * This behaviour will probably work on dongles that have the RESET line connected,
- * but if not, add a flag for the IR320ST-2, and implment the above-listed proper
- * behaviour.
- *
- * RTS is inverted and then fed to BR/~D, so to put it in programming mode, we

-F01 Oct/02/02: Modify code for V0.11(move out back to back transfer)
-F02 Oct/28/02: Add SB device ID for 3147 and 3177.
- Comment :
-       jul/09/2002 : only implement two kind of dongle currently.
-       Oct/02/2002 : work on VT8231 and VT8233 .
-       Aug/06/2003 : change driver format to pci driver .
-
-2004-02-16: <sda@bdit.de>
-- Removed unneeded 'legacy' pci stuff.
-- Make sure SIR mode is set (hw_init()) before calling mode-dependent stuff.
-- On speed change from core, don't send SIR frame with new speed. 
-  Use current speed and change speeds later.
-- Make module-param dongle_id actually work.
-- New dongle_id 17 (0x11): TDFS4500. Single-ended SIR only. 
-  Tested with home-grown PCB on EPIA boards.
-- Code cleanup.

-	 *
-	 * We select to operate using fixed MSTRPAGE=0, use ISA DMA
-	 * address restrictions to make the PCI BM api aware of this,
-	 * but ensure the hardware is dealing with real 32bit access.
-	 *
-	 * In detail:
-	 * The chip executes normal 32bit busmaster cycles, i.e.
-	 * drives all 32 address lines. These addresses however are
-	 * composed of [0:23] taken from various busaddr-pointers
-	 * and [24:31] taken from the MSTRPAGE register in the VLSI82C147
-	 * config space. Therefore _all_ busmastering must be
-	 * targeted to/from one single 16MB (busaddr-) superpage!
-	 * The point is to make sure all the allocations for memory
-	 * locations with busmaster access (ring descriptors, buffers)
-	 * are indeed bus-mappable to the same 16MB range (for x86 this
-	 * means they must reside in the same 16MB physical memory address
-	 * range). The only constraint we have which supports "several objects
-	 * mappable to common 16MB range" paradigma, is the old ISA DMA
-	 * restriction to the first 16MB of physical address range.
-	 * Hence the approach here is to enable PCI busmaster support using
-	 * the correct 32bit dma-mask used by the chip. Afterwards the device's
-	 * dma-mask gets restricted to 24bit, which must be honoured somehow by
-	 * all allocations for memory areas to be exposed to the chip ...
-	 *
-	 * Note:
-	 * Don't be surprised to get "Setting latency timer..." messages every
-	 * time when PCI busmastering is enabled for the chip.
-	 * The chip has its PCI latency timer RO fixed at 0 - which is not a
-	 * problem here, because it is never requesting _burst_ transactions.

- *		IrPHY also allows shorter pulses down to the nominal pulse duration
- *		at 115.2kbaud (minus some tolerance) which is 1.41 usec.
- *		Using the expression PLSWID = 12/(BAUD+1)-1 (multiplied by two for 48MHz)

- *		specification, which provides 1.5 usec pulse width for all speeds (except

- *		reduces the transceiver power which drains the battery. At 9.6kbaud for
- *		example this amounts to more than 90% battery power saving!

+ *			    IMPORTANT NOTE
+ *			    --------------
+ *
+ * As of kernel 2.5.20, this is the state of compliance and testing of
+ * this driver (irda-usb) with regards to the USB low level drivers...
+ *
+ * This driver has been tested SUCCESSFULLY with the following drivers :
+ *	o usb-uhci-hcd	(For Intel/Via USB controllers)
+ *	o uhci-hcd	(Alternate/JE driver for Intel/Via USB controllers)
+ *	o ohci-hcd	(For other USB controllers)
+ *
+ * This driver has NOT been tested with the following drivers :
+ *	o ehci-hcd	(USB 2.0 controllers)
+ *
+ * Note that all HCD drivers do URB_ZERO_PACKET and timeout properly,
+ * so we don't have to worry about that anymore.
+ * One common problem is the failure to set the address on the dongle,
+ * but this happens before the driver gets loaded...
+ *
+ * Jean II

+/*
+ * This is my current (2007-04-25) understanding of how this dongle is supposed
+ * to work. This is based on reverse-engineering and examination of the packet
+ * data sent and received by the WinXP driver using USBSnoopy. Feel free to
+ * update here as more of this dongle is known:
+ *
+ * General: Unlike the other USB IrDA dongles, this particular dongle exposes,
+ * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
+ * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
+ * order to receive data.
+ * Transmission: Just like stir4200, this dongle uses a raw stream of data,
+ * which needs to be wrapped and escaped in a similar way as in stir4200.c.
+ * Reception: Poll-based, as in stir4200. Each read returns the contents of a
+ * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
+ * (1-7) of valid data contained within the remaining 7 bytes. For example, if
+ * the buffer had the following contents:
+ *  06 ff ff ff c0 01 04 aa
+ * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
+ * end is garbage (left over from a previous reception) and is discarded.
+ * If a read returns an "impossible" value as the length of valid data (such as
+ * 0x36) in the first byte, then the buffer is uninitialized (as is the case of
+ * first plug-in) and its contents should be discarded. There is currently no
+ * evidence that the top 5 bits of the 1st byte of the buffer can have values
+ * other than 0 once reception begins.
+ * Once valid bytes are collected, the assembled stream is a sequence of
+ * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
+ * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
+ * a successful read from the host, which means that in absence of further
+ * reception, repeated reads from the dongle will return the exact same
+ * contents repeatedly. Attempts to be smart and cache a previous read seem
+ * to result in corrupted packets, so this driver depends on the unwrap logic
+ * to sort out any repeated reads.
+ * Speed change: no commands observed so far to change speed, assumed fixed
+ * 9600bps (SIR).

+/*
+ * Following is my most current (2007-07-17) understanding of how the Kingsun
+ * KS-959 dongle is supposed to work. This information was deduced by
+ * reverse-engineering and examining the USB traffic captured with USBSnoopy
+ * from the WinXP driver. Feel free to update here as more of the dongle is
+ * known.
+ *
+ * My most sincere thanks must go to Domen Puncer <domen@coderock.org> for
+ * invaluable help in cracking the obfuscation and padding required for this
+ * dongle.
+ *
+ * General: This dongle exposes one interface with one interrupt IN endpoint.
+ * However, the interrupt endpoint is NOT used at all for this dongle. Instead,
+ * this dongle uses control transfers for everything, including sending and
+ * receiving the IrDA frame data. Apparently the interrupt endpoint is just a
+ * dummy to ensure the dongle has a valid interface to present to the PC.And I
+ * thought the DonShine dongle was weird... In addition, this dongle uses
+ * obfuscation (?!?!), applied at the USB level, to hide the traffic, both sent
+ * and received, from the dongle. I call it obfuscation because the XOR keying
+ * and padding required to produce an USB traffic acceptable for the dongle can
+ * not be explained by any other technical requirement.
+ *
+ * Transmission: To transmit an IrDA frame, the driver must prepare a control
+ * URB with the following as a setup packet:
+ *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x09
+ *    wValue          <length of valid data before padding, little endian>
+ *    wIndex          0x0000
+ *    wLength         <length of padded data>
+ * The payload packet must be manually wrapped and escaped (as in stir4200.c),
+ * then padded and obfuscated before being sent. Both padding and obfuscation
+ * are implemented in the procedure obfuscate_tx_buffer(). Suffice to say, the
+ * designer/programmer of the dongle used his name as a source for the
+ * obfuscation. WTF?!
+ * Apparently the dongle cannot handle payloads larger than 256 bytes. The
+ * driver has to perform fragmentation in order to send anything larger than
+ * this limit.
+ *
+ * Reception: To receive data, the driver must poll the dongle regularly (like
+ * kingsun-sir.c) with control URBs and the following as a setup packet:
+ *    bRequestType    USB_DIR_IN | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x01
+ *    wValue          0x0200
+ *    wIndex          0x0000
+ *    wLength         0x0800 (size of available buffer)
+ * If there is data to be read, it will be returned as the response payload.
+ * This data is (apparently) not padded, but it is obfuscated. To de-obfuscate
+ * it, the driver must XOR every byte, in sequence, with a value that starts at
+ * 1 and is incremented with each byte processed, and then with 0x55. The value
+ * incremented with each byte processed overflows as an unsigned char. The
+ * resulting bytes form a wrapped SIR frame that is unwrapped and unescaped
+ * as in stir4200.c The incremented value is NOT reset with each frame, but is
+ * kept across the entire session with the dongle. Also, the dongle inserts an
+ * extra garbage byte with value 0x95 (after decoding) every 0xff bytes, which
+ * must be skipped.
+ *
+ * Speed change: To change the speed of the dongle, the driver prepares a
+ * control URB with the following as a setup packet:
+ *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x09
+ *    wValue          0x0200
+ *    wIndex          0x0001
+ *    wLength         0x0008 (length of the payload)
+ * The payload is a 8-byte record, apparently identical to the one used in
+ * drivers/usb/serial/cypress_m8.c to change speed:
+ *     __u32 baudSpeed;
+ *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
+ *    unsigned int : 1;
+ *    unsigned int stopBits : 1;
+ *    unsigned int parityEnable : 1;
+ *    unsigned int parityType : 1;
+ *    unsigned int : 1;
+ *    unsigned int reset : 1;
+ *    unsigned char reserved[3];    // set to 0
+ *
+ * For now only SIR speeds have been observed with this dongle. Therefore,
+ * nothing is known on what changes (if any) must be done to frame wrapping /
+ * unwrapping for higher than SIR speeds. This driver assumes no change is
+ * necessary and announces support for all the way to 57600 bps. Although the
+ * package announces support for up to 4MBps, tests with a Sony Ericcson K300
+ * phone show corruption when receiving large frames at 115200 bps, the highest
+ * speed announced by the phone. However, transmission at 115200 bps is OK. Go
+ * figure. Since I don't know whether the phone or the dongle is at fault, max
+ * announced speed is 57600 bps until someone produces a device that can run
+ * at higher speeds with this dongle.

+/*
+ * Following is my most current (2007-07-26) understanding of how the Kingsun
+ * 07D0:4100 dongle (sometimes known as the MA-660) is supposed to work. This
+ * information was deduced by examining the USB traffic captured with USBSnoopy
+ * from the WinXP driver. Feel free to update here as more of the dongle is
+ * known.
+ *
+ * General: This dongle exposes one interface with two interrupt endpoints, one
+ * IN and one OUT. In this regard, it is similar to what the Kingsun/Donshine
+ * dongle (07c0:4200) exposes. Traffic is raw and needs to be wrapped and
+ * unwrapped manually as in stir4200, kingsun-sir, and ks959-sir.
+ *
+ * Transmission: To transmit an IrDA frame, it is necessary to wrap it, then
+ * split it into multiple segments of up to 7 bytes each, and transmit each in
+ * sequence. It seems that sending a single big block (like kingsun-sir does)
+ * won't work with this dongle. Each segment needs to be prefixed with a value
+ * equal to (unsigned char)0xF8 + <number of bytes in segment>, inside a payload
+ * of exactly 8 bytes. For example, a segment of 1 byte gets prefixed by 0xF9,
+ * and one of 7 bytes gets prefixed by 0xFF. The bytes at the end of the
+ * payload, not considered by the prefix, are ignored (set to 0 by this
+ * implementation).
+ *
+ * Reception: To receive data, the driver must poll the dongle regularly (like
+ * kingsun-sir.c) with interrupt URBs. If data is available, it will be returned
+ * in payloads from 0 to 8 bytes long. When concatenated, these payloads form
+ * a raw IrDA stream that needs to be unwrapped as in stir4200 and kingsun-sir
+ *
+ * Speed change: To change the speed of the dongle, the driver prepares a
+ * control URB with the following as a setup packet:
+ *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x09
+ *    wValue          0x0200
+ *    wIndex          0x0001
+ *    wLength         0x0008 (length of the payload)
+ * The payload is a 8-byte record, apparently identical to the one used in
+ * drivers/usb/serial/cypress_m8.c to change speed:
+ *     __u32 baudSpeed;
+ *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
+ *    unsigned int : 1;
+ *    unsigned int stopBits : 1;
+ *    unsigned int parityEnable : 1;
+ *    unsigned int parityType : 1;
+ *    unsigned int : 1;
+ *    unsigned int reset : 1;
+ *    unsigned char reserved[3];    // set to 0
+ *
+ * For now only SIR speeds have been observed with this dongle. Therefore,
+ * nothing is known on what changes (if any) must be done to frame wrapping /
+ * unwrapping for higher than SIR speeds. This driver assumes no change is
+ * necessary and announces support for all the way to 115200 bps.

+ * As far as I can make it from info on their web site, the old dongle 
+ * support only 9600 b/s, which make our life much simpler as far as
+ * the driver is concerned, but you might not like it very much ;-)
+ * The new SmartBeam does 115 kb/s, and I've not tested it...
+ *
+ * Belkin claim that the correct driver for the old dongle (in Windows)
+ * is the generic Parallax 9500a driver, but the Linux LiteLink driver
+ * fails for me (probably because Linux-IrDA doesn't rate fallback),
+ * so I created this really dumb driver...
+ *
+ * In fact, this driver doesn't do much. The only thing it does is to
+ * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
+ * driver is called "old_belkin" so that when the new SmartBeam is supported
+ * its driver can be called "belkin" instead of "new_belkin".
+ *
+ * Note : this driver was written without any info/help from Belkin,

+ * PROTOCOL:
+ *
+ * The protocol for talking to the TOIM3232 is quite easy, and is
+ * designed to interface with RS232 with only level convertors. The
+ * BR/~D line on the chip is brought high to signal 'command mode',
+ * where a command byte is sent to select the baudrate of the RS232
+ * interface and the pulse length of the IRDA output. When BR/~D
+ * is brought low, the dongle then changes to the selected baudrate,
+ * and the RS232 interface is used for data until BR/~D is brought
+ * high again. The initial speed for the TOIMx323 after RESET is
+ * 9600 baud.  The baudrate for command-mode is the last selected
+ * baud-rate, or 9600 after a RESET.
+ *
+ * The  dongle I have (below) adds some extra hardware on the front end,
+ * but this is mostly directed towards pariasitic power from the RS232
+ * line rather than changing very much about how to communicate with
+ * the TOIM3232.
+ *
+ * The protocol to talk to the TOIM4232 chipset seems to be almost
+ * identical to the TOIM3232 (and the 4232 datasheet is more detailed)
+ * so this code will probably work on that as well, although I haven't
+ * tested it on that hardware.
+ *
+ * Target dongle variations that might be common:
+ *
+ * DTR and RTS function:
+ *   The data sheet for the 4232 has a sample implementation that hooks the
+ *   DTR and RTS lines to the RESET and BaudRate/~Data lines of the
+ *   chip (through line-converters). Given both DTR and RTS would have to
+ *   be held low in normal operation, and the TOIMx232 requires +5V to
+ *   signal ground, most dongle designers would almost certainly choose
+ *   an implementation that kept at least one of DTR or RTS high in
+ *   normal operation to provide power to the dongle, but will likely
+ *   vary between designs.
+ *
+ * User specified command bits:
+ *  There are two user-controllable output lines from the TOIMx232 that
+ *  can be set low or high by setting the appropriate bits in the
+ *  high-nibble of the command byte (when setting speed and pulse length).
+ *  These might be used to switch on and off added hardware or extra
+ *  dongle features.
+ *
+ *
+ * Target hardware: IRWave IR320ST-2
+ *
+ * 	The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
+ * 	TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transceiver.
+ * 	It uses a hex inverter and some discrete components to buffer and
+ * 	line convert the RS232 down to 5V.
+ *
+ * 	The dongle is powered through a voltage regulator, fed by a large
+ * 	capacitor. To switch the dongle on, DTR is brought high to charge
+ * 	the capacitor and drive the voltage regulator. DTR isn't associated
+ * 	with any control lines on the TOIM3232. Parisitic power is also taken
+ * 	from the RTS, TD and RD lines when brought high, but through resistors.
+ * 	When DTR is low, the circuit might lose power even with RTS high.
+ *
+ * 	RTS is inverted and attached to the BR/~D input pin. When RTS
+ * 	is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
+ * 	RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
+ * 	mode'.
+ *
+ * 	For some unknown reason, the RESET line isn't actually connected
+ * 	to anything. This means to reset the dongle to get it to a known
+ * 	state (9600 baud) you must drop DTR and RTS low, wait for the power
+ * 	capacitor to discharge, and then bring DTR (and RTS for data mode)
+ * 	high again, and wait for the capacitor to charge, the power supply
+ * 	to stabilise, and the oscillator clock to stabilise.
+ *
+ * 	Fortunately, if the current baudrate is known, the chipset can
+ * 	easily change speed by entering command mode without having to
+ * 	reset the dongle first.
+ *
+ * 	Major Components:
+ *
+ * 	- Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings
+ * 	  to IRDA pulse timings
+ * 	- 3.6864MHz crystal to drive TOIM3232 clock oscillator
+ * 	- DM74lS04M Inverting Hex line buffer for RS232 input buffering
+ * 	  and level conversion
+ * 	- PJ2951AC 150mA voltage regulator
+ * 	- Vishay/Temic TFDS4500	SIR IRDA front-end transceiver

+F01 Oct/02/02: Modify code for V0.11(move out back to back transfer)
+F02 Oct/28/02: Add SB device ID for 3147 and 3177.
+ Comment :
+       jul/09/2002 : only implement two kind of dongle currently.
+       Oct/02/2002 : work on VT8231 and VT8233 .
+       Aug/06/2003 : change driver format to pci driver .
+
+2004-02-16: <sda@bdit.de>
+- Removed unneeded 'legacy' pci stuff.
+- Make sure SIR mode is set (hw_init()) before calling mode-dependent stuff.
+- On speed change from core, don't send SIR frame with new speed. 
+  Use current speed and change speeds later.
+- Make module-param dongle_id actually work.
+- New dongle_id 17 (0x11): TDFS4500. Single-ended SIR only. 
+  Tested with home-grown PCB on EPIA boards.
+- Code cleanup.
+

+	 * We select to operate using fixed MSTRPAGE=0, use ISA DMA
+	 * address restrictions to make the PCI BM api aware of this,
+	 * but ensure the hardware is dealing with real 32bit access.
+	 *
+	 * In detail:
+	 * The chip executes normal 32bit busmaster cycles, i.e.
+	 * drives all 32 address lines. These addresses however are
+	 * composed of [0:23] taken from various busaddr-pointers
+	 * and [24:31] taken from the MSTRPAGE register in the VLSI82C147
+	 * config space. Therefore _all_ busmastering must be
+	 * targeted to/from one single 16MB (busaddr-) superpage!
+	 * The point is to make sure all the allocations for memory
+	 * locations with busmaster access (ring descriptors, buffers)
+	 * are indeed bus-mappable to the same 16MB range (for x86 this
+	 * means they must reside in the same 16MB physical memory address
+	 * range). The only constraint we have which supports "several objects
+	 * mappable to common 16MB range" paradigma, is the old ISA DMA
+	 * restriction to the first 16MB of physical address range.
+	 * Hence the approach here is to enable PCI busmaster support using
+	 * the correct 32bit dma-mask used by the chip. Afterwards the device's
+	 * dma-mask gets restricted to 24bit, which must be honoured somehow by
+	 * all allocations for memory areas to be exposed to the chip ...
+	 *
+	 * Note:
+	 * Don't be surprised to get "Setting latency timer..." messages every
+	 * time when PCI busmastering is enabled for the chip.
+	 * The chip has its PCI latency timer RO fixed at 0 - which is not a
+	 * problem here, because it is never requesting _burst_ transactions.

Subject: irda: move include/net/irda into staging subdirectory

And finally, move the irda include files into
drivers/staging/irda/include/net/irda.  Yes, it's a long path, but it
makes it easy for us to just add a Makefile directory path addition and
all of the net and drivers code "just works".

Subject: ftgmac100: Support NCSI VLAN filtering when available

Register the ndo_vlan_rx_{add,kill}_vid callbacks and set the
NETIF_F_HW_VLAN_CTAG_FILTER if NCSI is available.
This allows the VLAN core to notify the NCSI driver when changes occur
so that the remote NCSI channel can be properly configured to filter on
the set VLAN tags.

From 98fdbe73bfb809b1f8eec9f27a36e737caed3a44 Mon Sep 17 00:00:00 2001
From: Michael Chan <michael.chan@broadcom.com>

Subject: bnxt_en: Improve tx ring reservation logic.

When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX
rings, etc), the current code tries to reserve the new number of TX rings
before closing and re-opening the NIC.  If we are unable to reserve the
new TX rings, we abort the operation and keep the current TX rings.

The problem is that the firmware will disable the current TX rings even
when it cannot reserve the new set of TX rings.  We fix it as follows:

1. Instead of reserving the new set of TX rings, just ask the firmware
to check if the new set of TX rings is available.  There is a flag in
the firmware message to do that.  If not available, abort and the
current TX rings will not be disabled.

2. Do the actual TX ring reservation in the path that opens the NIC.
We keep the number of TX rings currently successfully reserved.  If the
number of TX rings is different than the reserved TX rings, we call
firmware and reserve again.

Subject: bnxt_en: assign CPU affinity hints to bnxt_en IRQs

This patch provides hints to irqbalance to map bnxt_en device IRQs
to specific CPU cores. cpumask_local_spread() is used, which first
maps IRQs to near NUMA cores; when those cores are exhausted, IRQs
are mapped to far NUMA cores.

Subject: bnxt_en: Improve -ENOMEM logic in NAPI poll loop.

If we cannot allocate RX buffers in the NAPI poll loop when processing
an RX event, the current code does not count that event towards the NAPI
budget.  This can cause us to potentially loop forever in NAPI if we
consistently cannot allocate new buffers.  Improve it by counting
-ENOMEM event as 1 towards the NAPI budget.

Subject: bnxt_en: fix clearing devlink ptr from bnxt struct

The routine bnxt_link_bp_to_dl() is used to set the devlink ptr
in bnxt struct (bp) and also to set the bnxt back ptr in
the devlink struct.  If devlink_register() fails, bp->dl must
be cleared which is not happening currently. This patch fixes
bnxt_link_bp_to_dl() to clear bp->dl by passing  a NULL dl ptr.

Subject: bnxt_en: bnxt: add TC flower filter offload support

This patch adds support for offloading TC based flow
rules and actions for the 'flower' classifier in the bnxt_en driver.
It includes logic to parse flow rules and actions received from the
TC subsystem, store them and issue the corresponding
hwrm_cfa_flow_alloc/free FW cmds. L2/IPv4/IPv6 flows and drop,
redir, vlan push/pop actions are supported in this patch.

In this patch the hwrm_cfa_flow_xxx routines are just stubs.
The code for these routines is introduced in the next patch for easier
review. Also, the code to query the TC/flower action stats will
be introduced in a subsequent patch.

Subject: drm/syncobj: Add a signal ioctl (v3)

This IOCTL provides a mechanism for userspace to trigger a sync object
directly.  There are other ways that userspace can trigger a syncobj
such as submitting a dummy batch somewhere or hanging on to a triggered
sync_file and doing an import.  This just provides an easy way to
manually trigger the sync object without weird hacks.

The motivation for this IOCTL is Vulkan fences.  Vulkan lets you create
a fence already in the signaled state so that you can wait on it
immediatly without stalling.  We could also handle this with a new
create flag to ask the driver to create a syncobj that is already
signaled but the IOCTL seemed a bit cleaner and more generic.

v2:
 - Take an array of sync objects (Dave Airlie)
v3:
 - Throw -EINVAL if pad != 0

Subject: dmaengine: altera: Use macros instead of structs to describe the
 registers

This patch moves from a struct declaration for the DMA controller
registers to macros with offests to the base address. This is mainly
done to remove the sparse warnings, since the function parameter of
ioread32/iowrite32 is "void __iomem *" instead of a pointer to struct
members. With this patch applied, no sparse warning is seen anymore.

Please note that the struct for the descriptors is still kept in place,
as the code largely accesses the struct members as internal variables
before the complete struct is copied into the descriptor FIFO of the
DMA controller.

Additionally this patch also removes two warnings "variable xxx set but
not used" seen when compiling with "W=1". The registers need to be read
to flush the response FIFO, but nothing needs to be done with them. So
the code is correct here and the warning is a false one.

We probably don't want to enable code supporting particular hardware by

don't do it.

Subject: staging: typec: tcpm: set port type callback

The port type callback call enquires the tcpc_dev if
the requested port type is supported. If supported, then
performs a tcpm reset if required after setting the tcpm
internal port_type variable.

Check against the tcpm port_type instead of checking
against caps.type as port_type reflects the current
configuration.

Subject: staging: typec: tcpm: Prevent TCPM from looping in SRC_TRYWAIT

According to the spec the following is the condition
for exiting TryWait.SRC:

"The port shall transition to Attached.SRC when V BUS is at vSafe0V
and the SRC.Rd state is detected on exactly one of the CC pins for at
least tCCDebounce. The port shall transition to Unattached.SNK after
tDRPTry if neither of the CC1 or CC2 pins are in the SRC.Rd state"

TCPM at present keeps re-entering the SRC_TRYWAIT and keeps restarting
tDRPTry if the CC presents Rp and disconnects within tCCDebounce.

For example:
[  447.164308] pending state change SRC_TRYWAIT -> SRC_ATTACHED @ 200 ms
[  447.164386] CC1: 2 -> 0, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, disconnected]
[  447.164406] state change SRC_TRYWAIT -> SRC_TRYWAIT
[  447.164573] cc:=3
[  447.191408] pending state change SRC_TRYWAIT -> SRC_TRYWAIT_UNATTACHED @ 100 ms
[  447.191478] CC1: 0 -> 0, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, disconnected]
[  447.207261] CC1: 0 -> 2, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, connected]
[  447.207306] state change SRC_TRYWAIT -> SRC_TRYWAIT
[  447.207485] cc:=3
[  447.237283] pending state change SRC_TRYWAIT -> SRC_ATTACHED @ 200 ms
[  447.237357] CC1: 2 -> 0, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, disconnected]
[  447.237379] state change SRC_TRYWAIT -> SRC_TRYWAIT
[  447.237532] cc:=3
[  447.263219] pending state change SRC_TRYWAIT -> SRC_TRYWAIT_UNATTACHED @ 100 ms
[  447.263289] CC1: 0 -> 0, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, disconnected]
[  447.280926] CC1: 0 -> 2, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, connected]
[  447.280970] state change SRC_TRYWAIT -> SRC_TRYWAIT
[  447.281158] cc:=3
[  447.307767] pending state change SRC_TRYWAIT -> SRC_ATTACHED @ 200 ms
[  447.307838] CC1: 2 -> 0, CC2: 0 -> 0 [state SRC_TRYWAIT, polarity 0, disconnected]
[  447.307858] state change SRC_TRYWAIT -> SRC_TRYWAIT

In TCPM, tDRPTry is set tp 100ms (min 75ms and max 150ms)
and tCCdebounce is set to 200ms (min 100ms and max 200ms).
To overcome the issue, record the time at which the port
enters TryWait.SRC(SRC_TRYWAIT) and re-enter SRC_TRYWAIT
only when CC keeps debouncing within tDRPTry.

Subject: staging: typec: tcpm: Check for Rp for tPDDebounce

According the spec, the following is the conditions for exiting Try.SNK
state:
"The port shall wait for tDRPTry and only then begin monitoring the CC1 and
CC2 pins for the SNK.Rp state. The port shall then transition to
Attached.SNK when the SNK.Rp state is detected on exactly one of the CC1
or CC2 pins for at least tPDDebounce and V BUS is detected. Alternatively,
the port shall transition to TryWait.SRC if SNK.Rp state is not detected
for tPDDebounce."

Subject: staging: typec: tcpm: add cc change handling in src states

In the case that the lower layer driver reports a cc change directly
from SINK state to SOURCE state, TCPM doesn't handle these cc change
in SRC_SEND_CAPABILITIES, SRC_READY states. And with SRC_ATTACHED

 excg

Once, Rp or Rd is switched, wait for PD_T_CC_DEBOUNCE. If not the
PS_RDY message transmitted might result in failure.
Also, Only wait for PD_T_SRCSWAPSTDBY while in
PR_SWAP_SRC_SNK_TRANSITION_OFF. PD_T_PS_SOURCE_OFF is the overall
time after which the initial sink would issue hard reset.

Subject: staging: typec: tcpm: Do not send PING msgs in TCPM

PING messages are used to monitor the connect/disconnect.
However, when PD is carried over CC, so this is not required.

Also, the spec does not clearly say if PD is possible when
Type-c is connected to Type-A/B. So, removing sending
PING messages altogether.

Subject: staging: typec: tcpm: Switch to PORT_RESET instead of SNK_UNATTACHED

When VBUS is not discovered within PD_T_PS_SOURCE_ON although Rp
is detected on CC, TCPM switches the port to SNK_UNATTACHED
state. SNK_UNATTACHED, however does not force TYPEC_CC_OPEN which
makes the partner(source) to think that it is connected.

To overcome this issue, force the port into PORT_RESET state
to make sure the CC lines are open.

Subject: nvme: remove nvme_revalidate_ns

The function is used in two places, and the shared code for those will
diverge later in this series.

Instead factor out a new helper to get the ids for a namespace, simplify
the calling conventions for nvme_identify_ns and just open code the
sequence.

Subject: clocksource/drivers/imx-tpm: Add imx tpm timer support

IMX Timer/PWM Module (TPM) supports both timer and pwm function while
this patch only adds the timer support. PWM would be added later.

The TPM counter, compare and capture registers are clocked by an
asynchronous clock that can remain enabled in low power modes.

NOTE: We observed in a very small probability, the bus fabric
contention between GPU and A7 may results a few cycles delay
of writing CNT registers which may cause the min_delta event got
missed, so we need add a ETIME check here in case it happened.

Subject: i2c-cht-wc: make cht_wc_i2c_adap_driver static

The structure cht_wc_i2c_adap_driver is local to the source
and does not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'cht_wc_i2c_adap_driver' was not declared. Should it be static?

Subject: power: supply: Add power_supply_set_input_current_limit_from_supplier
 helper

On some devices the USB Type-C port power (USB PD 2.0) negotiation is
done by a separate port-controller IC, while the current limit is
controlled through another (charger) IC.

It has been decided to model this by modelling the external Type-C
power brick (adapter/charger) as a power-supply class device which
supplies the charger-IC, with its voltage-now and current-max representing
the negotiated voltage and max current draw.

This commit adds a power_supply_set_input_current_limit_from_supplier
helper function which charger power-supply drivers can call to get
the max-current from their supplier and have this applied
through their set_property call-back to their input-current-limit.

From 3a731c6414c94012328f485b4b1bb88ed841f9eb Mon Sep 17 00:00:00 2001
From: Liam Breck <kernel@networkimprov.net>

Subject: power: supply: bq27xxx: Add chip IDs for previously shadowed chips

For the existing features, these chips act like others already ID'd,
so they had false but functional IDs. We will be adding features
which require correct IDs, so the following IDs are added:
BQ2752X, 531, 542, 546, 742, 425, 441, 621

Chip-specific features are now tracked by BQ27XXX_O_* flags in di->opts.

No functional changes to the driver.

From 05045379b2740686020618c8cfd4b517cff9f918 Mon Sep 17 00:00:00 2001
From: Liam Breck <kernel@networkimprov.net>
Date: Wed, 23 Aug 2017 20:36:15 -0700
Subject: power: supply: bq27xxx: Enable data memory update for certain chips

Support data memory update on BQ27425. Parameters from TI datasheets are also
provided for BQ27500, 545, 421, 441, 621; however these are commented out,
as they are not tested.

Add BQ27XXX_O_CFGUP & _O_RAM for use in bq27xxx_chip_data[n].opts
and by data memory update functions.

Subject: mux: make device_type const

Make this const as it is only stored in the type field of a device
structure, which is const.
Done using Coccinelle.

Subject: IB/core: Separate CQ handle in SRQ context

Before this change CQ attached to SRQ was part of XRC specific extension.
Moving CQ handle out makes it available to other types extending SRQ
functionality.

Subject: IB/uverbs: Add new SRQ type IB_SRQT_TM

Add new SRQ type capable of new tag matching feature.

When SRQ receives a message it will search through the matching list
for the corresponding posted receive buffer. The process of searching
the matching list is called tag matching.

In case the tag matching results in a match, the received message will
be placed in the address specified by the receive buffer. In case no
match was found the message will be placed in a generic buffer until the
corresponding receive buffer will be posted. These messages are called
unexpected and their set is called an unexpected list.

Subject: smp: Avoid using two cache lines for struct call_single_data

struct call_single_data is used in IPIs to transfer information between
CPUs.  Its size is bigger than sizeof(unsigned long) and less than
cache line size.  Currently it is not allocated with any explicit alignment
requirements.  This makes it possible for allocated call_single_data to
cross two cache lines, which results in double the number of the cache lines
that need to be transferred among CPUs.

This can be fixed by requiring call_single_data to be aligned with the
size of call_single_data. Currently the size of call_single_data is the
power of 2.  If we add new fields to call_single_data, we may need to
add padding to make sure the size of new definition is the power of 2
as well.

Fortunately, this is enforced by GCC, which will report bad sizes.

To set alignment requirements of call_single_data to the size of
call_single_data, a struct definition and a typedef is used.

To test the effect of the patch, I used the vm-scalability multiple
thread swap test case (swap-w-seq-mt).  The test will create multiple
threads and each thread will eat memory until all RAM and part of swap
is used, so that huge number of IPIs are triggered when unmapping
memory.  In the test, the throughput of memory writing improves ~5%
compared with misaligned call_single_data, because of faster IPIs.

Subject: acpi/nfit: Fix COMPLETION_INITIALIZER_ONSTACK() abuse

COMPLETION_INITIALIZER_ONSTACK() is supposed to be used as an initializer,
in other words, it should only be used in assignment expressions or
compound literals. So the usage in drivers/acpi/nfit/core.c:

	COMPLETION_INITIALIZER_ONSTACK(flush.cmp);

... is inappropriate.

Besides, this usage could also break the build for another fix that
reduces stack sizes caused by COMPLETION_INITIALIZER_ONSTACK(), because
that fix changes COMPLETION_INITIALIZER_ONSTACK() from rvalue to lvalue,
and usage as above will report the following error:

	drivers/acpi/nfit/core.c: In function 'acpi_nfit_flush_probe':
	include/linux/completion.h:77:3: error: value computed is not used [-Werror=unused-value]
	  (*({ init_completion(&work); &work; }))

This patch fixes this by replacing COMPLETION_INITIALIZER_ONSTACK()
with init_completion() in acpi_nfit_flush_probe(), which does the
same initialization without any other problems.

Subject: MIPS: Alchemy: Threaded carddetect irqs for devboards

This introduces threaded carddetect irqs for the db1200/db1300 boards.
Main benefit is that the broken insertion/ejection interrupt pairs
can now be better supported and debounced in software.

Subject: MIPS: CM: Use BIT/GENMASK for register fields, order & drop shifts

There's no reason for us not to use BIT() & GENMASK() in asm/mips-cm.h
when declaring macros corresponding to register fields. This patch
modifies our definitions to do so.

The *_SHF definitions are removed entirely - they duplicate information
found in the masks, are infrequently used & can be replaced with use of
__ffs() where needed.

The *_MSK definitions then lose their _MSK suffix which is now somewhat
redundant, and users are modified to match.

The field definitions are moved to follow the appropriate register's
accessor functions, which helps to keep the field definitions in order &
to find the appropriate fields for a given register. Whilst here a
comment is added describing each register & including its name, which is
helpful both for linking the register back to hardware documentation &
for grepping purposes.

This also cleans up a couple of issues that became obvious as a result
of making the changes described above:

  - We previously had definitions for GCR_Cx_RESET_EXT_BASE & a phony
    copy of that named GCR_RESET_EXT_BASE - a register which does not
    exist. The bad definitions were added by commit 497e803ebf98 ("MIPS:
    smp-cps: Ensure secondary cores start with EVA disabled") and made
    use of from boot_core(), which is now modified to use the
    GCR_Cx_RESET_EXT_BASE definitions.

  - We had a typo in CM_GCR_ERROR_CAUSE_ERRINGO_MSK - we now correctly
    define this as inFo rather than inGo.

Now that we don't duplicate field information between _SHF & _MSK
definitions, and keep the fields next to the register accessors, it will
be much easier to spot & prevent any similar oddities being introduced
in the future.

Subject: clocksource/drivers/bcm2835: Remove message for a memory allocation
 failure

The bcm2835_timer_init() function emits an error message in case of a memory
allocation failure. This is pointless as the mm core does that already.

Remove this message.

This issue was detected by using the Coccinelle software.

Subject: virt: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Get rid of the goto and "out" label within vmcp_response_free() which
I added. This just makes the code harder to read than necessary.

Subject: s390/dasd: Add discard support for FBA devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The z/VM hypervisor provides virtual disks (VDISK) which are backed by
main memory of the hypervisor. Those devices are seen as DASD FBA disks
within the Linux guest.

Whenever data is written to such a device, memory is allocated
on-the-fly by z/VM accordingly. This memory, however, is not being freed
if data on the device is deleted by the guest OS.

In order to make memory usable after deletion again, add discard support
to the FBA discipline.

While at it, update comments regarding the DASD_FEATURE_* flags.

Subject: libata: check for trusted computing in IDENTIFY DEVICE data

ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of
the IDENTIFY DEVICE data.  Check this before issuing a READ LOG PAGE
command to avoid issues with buggy devices.  The only downside is that
we can't support Security Send / Receive for a device with an older
revision due to the conflicting use of this field in earlier
specifications.

tj: The reason we need this is because some devices which don't
    support READ LOG PAGE lock up after getting issued that command.

We now conditionalize issuing of READ LOG PAGE on the TRUSTED

necessary.

Since blk_mq_init_queue() initializes .nr_requests to the tag set

not overwrite the value set by blk_mq_init_queue(). This change
doubles the default value of .nr_requests.

Subject: mtd: nand: make Samsung SLC NAND usable again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit c51d0ac59f24 ("mtd: nand: Move Samsung specific init/detection
logic in nand_samsung.c") introduced a regression for Samsung SLC NAND
chips. Prior to this commit chip->bits_per_cell was initialized by calling
nand_get_bits_per_cell() before using nand_is_slc().
With the offending commit this call is skipped, leaving
chip->bits_per_cell cleared to zero when the manufacturer specific
'.detect' function calls nand_is_slc() which in turn interprets
bits_per_cell != 1 as indication for an MLC chip.
The effect is that e.g. a K9F1G08U0F NAND chip is falsely detected as
MLC NAND with 4KiB page size rather than SLC with 2KiB page size.

Add a call to nand_get_bits_per_cell() before calling the .detect hook
function in nand_manufacturer_detect(), so that the nand_is_slc()
calls in the manufacturer specific code will return correct results.

explicitly state whether the driver needs exclusive or shared reset control
behavior. Convert all drivers requesting exclusive resets to the explicit
API call so the temporary transition helpers can be removed.

Factor out rockchip_pcie_enable_clocks() so it can be reused by
rockchip_pcie_resume_noirq() and rockchip_pcie_probe().

No functional change intended, but it does change the order of unpreparing

Subject: PCI: rockchip: Clean up PHY if driver probe or resume fails

We observed that the clk_pciephy_ref is still enabled when we fail to probe
the driver.

		  aclk_perf_pcie     0     0       148500000       0 0
			  pclk_pcie  0     0        37125000       0 0
  clk_pcie_core                      0     0               0       0 0

clk_pciephy_ref is used by the PHY driver and we need to properly disable
it for this case.  Add error handling in rockchip_pcie_init_port() and
rockchip_pcie_resume_noirq() to fix this issue.

In case platform data provided empty LED name string the resulting
LED class device name would be crippled. Use corresponding LED chip
bit in place of "function" segment of LED class device name then to
make the LEDs at least distinguishable.

Subject: PCI: Always check for non-CRS response before timeout

While waiting for a device to become ready (i.e., to return a non-CRS
completion to a read of its Vendor ID), if we got a valid response to the
very last read before timing out, we printed a warning and gave up on the
device even though it was actually ready.

For a typical 60s timeout, we wait about 65s (it's not exact because of the
exponential backoff), but we treated devices that became ready between 33s
and 65s as though they failed.

Move the Device ID read later so we check whether the device is ready
before checking for a timeout.

Thanks to Sinan Kaya <okaya@codeaurora.org>, reorder reads so we always
check device presence after sleep, since it's pointless to sleep unless we
recheck afterwards.

Subject: PCI: Add pci_bus_crs_vendor_id() to detect CRS response data

Add pci_bus_crs_vendor_id() to determine whether data returned for a config
read of the Vendor ID indicates a Configuration Request Retry Status (CRS)
response.

Per PCIe r3.1, sec 2.3.2, this data is only returned if:

  - CRS Software Visibility is enabled,
  - a config read includes both bytes of the Vendor ID, and
  - the read receives a CRS completion

Configuration Request Retry Status (CRS) was previously hidden inside
pci_bus_read_dev_vendor_id().  We want to add support for CRS in other
situations, such as waiting for a device to become ready after a Function
Level Reset.

Move CRS handling into pci_bus_wait_crs() so it can be called from other
places.

Subject: PCI: Wait up to 60 seconds for device to become ready after FLR

Sporadic reset issues have been observed with an Intel 750 NVMe drive while
assigning the physical function to the guest machine.  The sequence of
events observed is as follows:

  - perform a Function Level Reset (FLR)
  - sleep up to 1000ms total
  - read ~0 from PCI_COMMAND (CRS completion for config read)
  - warn that the device didn't return from FLR
  - touch the device before it's ready
  - device drops config writes when we restore register settings (there's
    no mechanism for software to learn about CRS completions for writes)
  - incomplete register restore leaves device in inconsistent state
  - device probe fails because device is in inconsistent state

After reset, an endpoint may respond to config requests with Configuration
Request Retry Status (CRS) to indicate that it is not ready to accept new
requests. See PCIe r3.1, sec 2.3.1 and 6.6.2.

Increase the timeout value from 1 second to 60 seconds to cover the period
where device responds with CRS and also report polling progress.

Subject: spi: imx: fix use of native chip-selects with devicetree

The commonly used mechanism of specifying the hardware or native
chip-select on an SPI device in devicetree (that is "cs-gpios = <0>")
does not result in the native chip-select being configured for use.
So external SPI devices that require use of the native chip-select
will not work.

You can successfully specify native chip-selects if using a platform
setup by specifying the cs-gpio as negative offset by 32. And that
works correctly. You cannot use the same method in devicetree.

The logic in the spi-imx.c driver during probe uses core spi function
of_spi_register_master() in spi.c to parse the "cs-gpios" devicetree tag.
For valid GPIO values that will be recorded for use, all other entries in
the cs_gpios list will be set to -ENOENT. So entries like "<0>" will be
set to -ENOENT in the cs_gpios list.

When the SPI device registers are setup the code will use the GPIO
listed in the cs_gpios list for the desired chip-select. If the cs_gpio
is less then 0 then it is intended to be for a native chip-select, and
its cs_gpio value is added to 32 to get the chipselect number to use.
Problem is that with devicetree this can only ever be -ENOENT (which
is -2), and that alone results in an invalid chip-select number. But also
doesn't allow selection of the native chip-select at all.

To fix, if the cs_gpio specified for this spi device is not a
valid GPIO then use the "chip_select" (that is the native chip-select
number) for hardware setup.

Subject: i2c: ismt: Don't duplicate the receive length for block reads

According to Table 15-14 of the C2000 EDS (Intel doc #510524) the
rx data pointed to by the descriptor dptr contains the byte count.

desc->rxbytes reports all bytes read on the wire, including the
"byte count" byte.  So if a device sends 4 bytes in response to a
block read, on the wire and in the DMA buffer we see:

count data1 data2 data3 data4
 0x04  0xde  0xad  0xbe  0xef

That's what we want to return in data->block to the next level.

Instead we were actually prefixing that with desc->rxbytes:

bad
count count data1 data2 data3 data4
 0x05  0x04  0xde  0xad  0xbe  0xef

This was discovered while developing a BMC solution relying on the
ipmi_ssif.c driver which was trying to interpret the bogus length
field as part of the IPMI response.

Compare the number of bytes actually seen on the wire to the byte
count field returned by the slave device.

Previously we just overwrote the byte count returned by the slave

message was sane.

We called dw_pcie_setup_rc() from the ls1021a host init function, but not
from the common ls_pcie_host_init() function, so platforms other than
ls1021a still depended on initialization by the bootloader.

Call dw_pcie_setup_rc() from ls_pcie_host_init() to reduce dependencies on
the bootloader.

Subject: i2c: busses: make i2c_adapter_quirks const

Make these const as they are only stored as a reference in the quirks
field of an i2c_adapter structure, which is const. Done using
Coccinelle.

Subject: PCI: endpoint: Add support for configurable page size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pci-epc-mem uses a page size equal to *PAGE_SIZE* (usually 4KB) to manage
the address space. However certain platforms like TI's K2G have a
restriction that this address space should be either divided into
1MB/2MB/4MB or 8MB sizes (Ref: 11.14.4.9.1 Outbound Address Translation in
K2G TRM SPRUHY8F January 2016 – Revised May 2017).  Add support to handle
different page sizes here.

Subject: PCI: endpoint: Add "volatile" to pci_epf_test_reg

struct pci_epf_test_reg is the MEMSPACE of pci-epf-test function driver
that will be accessed by the "host" for programming the pci-epf-test
device. So this structure shouldn't be subjected to compiler optimization
in pci_epf_test_cmd_handler() since the values can be changed by code
outside the scope of current code at any time.

Subject: PCI: endpoint: Do not reset *command* inadvertently

pci_epf_test_cmd_handler() is the delayed work function which reads
*command* (set by the host) and performs various actions requested by the
host periodically. If the value in *command* is '0', it goes to the
reset_handler where it resets *command* to '0' and queues
pci_epf_test_cmd_handler().

However if the host writes a value to the *command* just after the
pci-epf-test driver checks *command* for '0' and before the control goes to
reset_handler, the *command* will be reset to '0' and the pci-epf-test
driver won't be able to perform the actions requested by the host.  Fix it
here by not resetting the *command* in the reset_handler.

Subject: PCI: endpoint: Add support to use _any_ BAR to map PCI_ENDPOINT_TEST
 regs

pci_epf_test always maps the PCI_ENDPOINT_TEST registers to BAR_0. But if
BAR_0 is reserved for some other purpose (like in TI's K2G BAR_0 is mapped
to application registers and cannot be used to map any other regions),
PCI_ENDPOINT_TEST registers cannot be mapped making pci_epf_test unusable.
Add support to use any BAR to map PCI_ENDPOINT_TEST registers.

epf_test is allocated using devm_kzalloc(). Hence it's not required to
explicitly free it in remove() callback. Since ->remove() callback doesn't
do anything other than freeing epf_test, remove the ->remove() callback.

Subject: misc: pci_endpoint_test: Add support for PCI_ENDPOINT_TEST regs to be
 mapped to any BAR

pci_endpoint_test driver assumes the PCI_ENDPOINT_TEST registers will
always be mapped to BAR_0. This need not always be the case like in TI's
K2G where BAR_0 is mapped to PCI controller application registers.

Add support so that PCI_ENDPOINT_TEST registers can be mapped to any BAR.
Change the bar_size used for BAR test accordingly.

Subject: misc: pci_endpoint_test: Add support to not enable MSI interrupts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Some platforms like TI's K2G have a restriction that the host side buffer
address should be aligned to either 1MB/2MB/4MB or 8MB addresses depending
on how it is configured in the endpoint (Ref: 11.14.4.9.1 Outbound Address
Translation in K2G TRM SPRUHY8F January 2016 – Revised May 2017). This
restriction also applies to the MSI addresses provided by the RC. However
it's not possible for the RC to know about this restriction and it may not
provide 1MB/2MB/4MB or 8MB aligned address. So MSI interrupts should be
disabled even if the K2G EP has MSI capabiltiy register.

Add support to not enable MSI interrupts in pci_endpoint_test driver so
that it can be used to test K2G EP.

Subject: misc: pci_endpoint_test: Avoid using hard-coded BAR sizes

BAR sizes are hard-coded in pci_endpoint_test driver corresponding to the
sizes used in pci-epf-test function driver. This might break if the sizes
in pci-epf-test function driver are modified (and the corresponding change
is not done in pci_endpoint_test PCI driver).

To avoid hard coding BAR sizes, use pci_resource_len() API.

Subject: misc: pci_endpoint_test: Enable/Disable MSI using module param

In certain platforms like TI's DRA7 SoCs, use of legacy PCI interrupt is
exclusive with use of MSI (Section 24.9.4.6.2.1 Legacy PCI Interrupts in
http://www.ti.com/lit/ug/spruhz6i/spruhz6i.pdf).

However pci_endpoint_test driver enables MSI by default in probe.  In order
for pci_endpoint_test to be able to test legacy interrupt, MSI should be
disabled. Add a module param 'no_msi' to disable MSI (only when legacy
interrupt has to be tested).

Subject: drm/vmwgfx: Fix F26 Wayland screen update issue

vmwgfx currently cannot support non-blocking commit because when
vmw_*_crtc_page_flip is called, drm_atomic_nonblocking_commit()
schedules the update on a thread.  This means vmw_*_crtc_page_flip
cannot rely on the new surface being bound before the subsequent
dirty and flush operations happen.

The read-only DBI registers can be written only when the "Write to RO
Registers Using DBI" (DBI_RO_WR_EN) field of MISC_CONTROL_1_OFF is set.

Add accessors to enable and disable write permission, and use them instead
of accessing MISC_CONTROL_1_OFF directly.

Subject: rpmsg: glink: Associate indirections for pipe fifo accessor's

With the intention of reusing the glink core protocol commands and code
across both rpm and smem based transports, the only thing different is
way of accessing the shared-memory of the transport (FIFO). So put the
fifo accessor's of the transport's pipe (rx/tx) behind indirections, so
that the rest of the code can be shared.

For this, have a qcom_glink_pipe that can be used in the common code
containing the indirections and wrap it with glink_rpm_pipe that
contains the transport specific members.

Subject: rpmsg: glink: Split rpm_probe to reuse the common code

There is quite some code common in glink_rpm_probe that can reused for
glink-smem based transport as well. So split the function and move the
code to glink_native_probe that can be used later when we add the
support for glink-smem based transport. Also reuse driver's remove as
well.

Subject: rpmsg: glink: Allow unaligned data access

Glink protocol requires that each message is aligned on a 8 byte offset.
This is purely a restriction from glink, so in order to support clients
which do not adher to this, allow data packets of any size, but align
the head index accordingly, effectively removing the alignment
restriction.

The TX FIFO can be full, if the remote client has not read enough data
(or) reading it slowly. So its nessecary to return -EAGAIN to the local
client to enable retry.

Subject: drbd: introduce drbd_recv_header_maybe_unplug

Recently, drbd_recv_header() was changed to potentially
implicitly "unplug" the backend device(s), in case there
is currently nothing to receive.

Be more explicit about it: re-introduce the original drbd_recv_header(),
and introduce a new drbd_recv_header_maybe_unplug() for use by the
receiver "main loop".

Using explicit plugging via blk_start_plug(); blk_finish_plug();
really helps the io-scheduler of the backend with merging requests.

Wrap the receiver "main loop" with such a plug.
Also catch unplug events on the Primary,
and try to propagate.

This is performance relevant.  Without this, if the receiving side does
not merge requests, number of IOPS on the peer can me significantly
higher than IOPS on the Primary, and can easily become the bottleneck.

Together, both changes should help to reduce the number of IOPS
as seen on the backend of the receiving side, by increasing
the chance of merging mergable requests, without trading latency
for more throughput.

Subject: drbd: add explicit plugging when submitting batches

When submitting batches of requests which had been queued on the
submitter thread, typically because they needed to wait for an
activity log transactions, use explicit plugging to help potential
merging of requests in the backend io-scheduler.

Subject: drbd: Send P_NEG_ACK upon write error in protocol != C

In protocol != C, we forgot to send the P_NEG_ACK for failing writes.

Once we no longer submit to local disk, because we already "detached",
due to the typical "on-io-error detach;" config setting,
we already send the neg acks right away.

Only those requests that have been submitted,
and have been error-completed by the local disk,
would forget to send the neg-ack,
and only in asynchronous replication (protocol != C).
Unless this happened during resync,
where we already always send acks, regardless of protocol.

The primary side needs the P_NEG_ACK in order to mark
the affected block(s) for resync in its out-of-sync bitmap.

If the blocks in question are not re-written again,
we may miss to resync them later, causing data inconsistencies.

This patch will always send the neg-acks, and also at least try to
persist the out-of-sync status on the local node already.

drbd/drbd_req.c:1450:6: warning: no previous prototype for 'send_and_submit_pending' [-Wmissing-prototypes]

....

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

Subject: drbd: Fix resource role for newly created resources in events2

The conn_higest_role() (a terribly misnamed function) returns
the role of the resource. It returned R_UNKNOWN as long as the
resource has not a single device.

Resources without devices are short living objects.

But it matters for the NOTIFY_CREATE netwlink message. It makes
a lot more sense to report R_SECONDARY for the newly created
resource than R_UNKNOWN.

I reviewd all call sites of conn_highest_role(), that change
does not matter for the other call sites.

                                | while in this context,
                                | this is the next statement.
                                | which means this context was scheduled

device->ldev = nbc;             |
                                |       if (device->ldev)
                                |               put_ldev()

Unlikely, but possible. I was able to provoke it "reliably"
by adding an mdelay(500); after the wake_up().
Fixed by moving the if (!NULL) put_ldev() before done = 1;

Impact of the bug was that the resulting refcount imbalance
could lead to premature destruction of the object, potentially
causing a NULL pointer dereference during a subsequent detach.

Subject: drbd: fix rmmod cleanup, remove _all_ debugfs entries

If there are still resources defined, but "empty", no more volumes
or connections configured, they don't hold module reference counts,
so rmmod is possible.

To avoid DRBD leftovers in debugfs, we need to call our global
drbd_debugfs_cleanup() only after all resources have been cleaned up.

Subject: drbd: fix potential deadlock when trying to detach during handshake

When requesting a detach, we first suspend IO, and also inhibit meta-data IO
by means of drbd_md_get_buffer(), because we don't want to "fail" the disk
while there is IO in-flight: the transition into D_FAILED for detach purposes
may get misinterpreted as actual IO error in a confused endio function.

We wrap it all into wait_event(), to retry in case the drbd_req_state()
returns SS_IN_TRANSIENT_STATE, as it does for example during an ongoing
connection handshake.

In that example, the receiver thread may need to grab drbd_md_get_buffer()
during the handshake to make progress.  To avoid potential deadlock with
detach, detach needs to grab and release the meta data buffer inside of
that wait_event retry loop. To avoid lock inversion between
mutex_lock(&device->state_mutex) and drbd_md_get_buffer(device),
introduce a new enum chg_state_flag CS_INHIBIT_MD_IO, and move the
call to drbd_md_get_buffer() inside the state_mutex grabbed in
drbd_req_state().

Subject: drbd: fix race between handshake and admin disconnect/down

conn_try_disconnect() could potentialy hit the BUG_ON()
in _conn_set_state() where it iterates over _drbd_set_state()
and "asserts" via BUG_ON() that the latter was successful.

If the STATE_SENT bit was not yet visible to conn_is_valid_transition()
early in _conn_request_state(), but became visible before conn_set_state()
later in that call path, we could hit the BUG_ON() after _drbd_set_state(),
because it returned SS_IN_TRANSIENT_STATE.

To avoid that race, we better protect set_bit(SENT_STATE) with the spinlock.

Subject: drbd: rename "usermode_helper" to "drbd_usermode_helper"

Nothing like having a very generic global variable in a tiny driver
subsystem to make a mess of the global namespace...

Note, there are many other "generic" named global variables in the drbd
subsystem, someone should fix those up one day before they hit a linking
error.

Subject: drbd: move global variables to drbd namespace and make some static

This is a follow-up to Gregs complaints that drbd clutteres the global
namespace.
Some of DRBD's module parameters are only used within one compilation
unit. Make these static.

Previously we enabled writes to the DBI read-only registers so the Class
Code fix in dw_pcie_setup_rc() would work.  But now dw_pcie_setup_rc()
enables write permission itself, so we don't need to do it here.

Stop enabling writes to the DBI read-only registers.

Subject: net: systemport: Use correct I/O accessors

The SYSTEMPORT driver currently uses __raw_{read,write}l which means
native I/O endian. This works correctly for an ARM LE kernel (default)
but fails miserably on an ARM BE (BE8) kernel where registers are kept
little endian, so replace uses with {read,write}l_relaxed here which is
what we want because this is all performance sensitive code.

Subject: net: dsa: bcm_sf2: Use correct I/O accessors

The Starfigther 2 driver currently uses __raw_{read,write}l which means
native I/O endian. This works correctly for an ARM LE kernel (default)
but fails miserably on an ARM BE (BE8) kernel where registers are kept
little endian, so replace uses with {read,write}l_relaxed here which is
what we want because this is all performance sensitive code.

Subject: net: systemport: Set correct RSB endian bits based on host

RSB_SWAP0 needs to match the host CPU endian, and it needs to be set
for LE and clear for BE. RSB_SWAP1 must always be cleared for SYSTEMPORT
Lite.

With these settings, we have the Receive Status Block always match the
host endian and we do not need to perform any conversion. Since there is
not necessarily a CONFIG_CPU_LITTLE_ENDIAN option defined, we test for
!CONFIG_CPU_BIG_ENDIAN which is guaranteed to be set.

Subject: net: phy: mdio-bcm-unimac: Use correct I/O accessors

The driver currently uses __raw_{read,write}l which works for all
platforms supported: Broadcom MIPS LE/BE (native endian), ARM LE (native
endian) but not ARM BE (registers are still LE). Switch to using the
proper accessors for all platforms and explain why Broadcom MIPS BE is
special here, in doing so, we introduce a couple of helper functions to
abstract these differences.

Subject: net/mlx4_core: Make explicit conversion to 64bit value

The "lg" variable is declared as int so in all places where this variable
is used as a shift operand, the output will be int too.

This produces the following smatch warning:
drivers/net/ethernet/mellanox/mlx4/fw.c:1532 mlx4_map_cmd() warn:
	should '1 << lg' be a 64 bit type?

Simple declaration of "1" to be "1ULL" will fix the issue.

Subject: net/mlx4: Add user mac FW update support

Adding support for updating the FW on new port mac, when port mac change
is requested by the user. This info is required by the FW as OEM
management tools require this info directly from the NIC FW.
Check device capability bit to verify the FW supports user mac.
If the FW does support it, use set_port command to notify the FW on the
new mac.
The feature is relevant only to PF port mac.

The hardware has the HW Checksum Offload bug when small
TCP patckets (with length <= 60 bytes) has wrong "checksum valid" bit.

The solution is - ignore checksum valid bit for small packets
(with length <= 60 bytes) and mark this as CHECKSUM_NONE to allow
network stack recalculate checksum itself.

Subject: net:ethernet:aquantia: Fix for multicast filter handling.

Since the HW supports up to 32 multicast filters we should
track count of multicast filters to avoid overflow.
If we attempt to add >32 multicast filter - just set NETIF_ALLMULTI flag
instead.

Subject: vxlan: factor out VXLAN-GPE next protocol

The values are shared between VXLAN-GPE and NSH. Originally probably by
coincidence but I notified both working groups about this last year and they
seem to keep the values in sync since then.

Hopefully they'll get a single IANA registry for the values, too. (I asked
them for that.)

Factor out the code to be shared by the NSH implementation.

NSH and MPLS values are added in this patch, too. For MPLS, the drafts
incorrectly assign only a single value, while we have two MPLS ethertypes.
I raised the problem with both groups. For now, I assume the value is for
unicast.

Subject: PCI: Disable VF decoding before pcibios_sriov_disable() updates
 resources

A struct resource represents the address space consumed by a device.  We
should not modify that resource while the device is actively using the
address space.  For VFs, pci_iov_update_resource() enforces this by
printing a warning and doing nothing if the VFE (VF Enable) and MSE (VF
Memory Space Enable) bits are set.

Previously, both sriov_enable() and sriov_disable() called the
pcibios_sriov_disable() arch hook, which may update the struct resource,
while VFE and MSE were enabled.  This effectively dropped the resource
update pcibios_sriov_disable() intended to do.

Disable VF memory decoding before calling pcibios_sriov_disable().

Subject: amd-xgbe: Interrupt summary bits are h/w version dependent

There is a difference in the bit position of the normal interrupt summary
enable (NIE) and abnormal interrupt summary enable (AIE) between revisions
of the hardware.  For older revisions the NIE and AIE bits are positions
16 and 15 respectively.  For newer revisions the NIE and AIE bits are
positions 15 and 14.  The effect in changing the bit position is that
newer hardware won't receive AIE interrupts in the current version of the
driver.  Specifically, the driver uses this interrupt to collect
statistics on when a receive buffer unavailable event occurs and to
restart the driver/device when a fatal bus error occurs.

Update the driver to set the interrupt enable bit based on the reported
version of the hardware.

Subject: MIPS: Abstract CPU core & VP(E) ID access through accessor functions

We currently have fields in struct cpuinfo_mips for the core & VP(E) ID
of a particular CPU, and various pieces of code directly access those
fields. This patch abstracts such access by introducing accessor
functions cpu_core(), cpu_set_core(), cpu_vpe_id() & cpu_set_vpe_id()
and having code that needs to access these values call those functions
rather than directly accessing the struct cpuinfo_mips fields. This
prepares us for changes to the way in which those values are stored in
later patches.

The cpu_vpe_id() function is introduced even though we already had a
cpu_vpe_id() macro for a couple of reasons:

  1) It's more consistent with the core, and future cluster, accessors.

  2) It ensures a sensible return type without explicit casts.

  3) It's generally preferable to use functions rather than macros.

Subject: MIPS: Unify checks for sibling CPUs

Up until now we have open-coded checks for whether CPUs are siblings,
with slight variations on whether we consider the package ID or not.

This will only get more complex when we introduce cluster support, so in
preparation for that this patch introduces a cpus_are_siblings()
function which can be used to check whether or not 2 CPUs are siblings
in a consistent manner.

By checking globalnumber with the VP ID masked out this also has the
neat side effect of being ready for multi-cluster systems already.

Subject: MIPS: CPS: Have asm/mips-cps.h include CM & CPC headers

With Coherence Manager (CM) 3.5 information about the topology of the
system, which has previously only been available through & accessed from
the CM, is now also provided by the Cluster Power Controller (CPC). This
includes a new CPC_CONFIG register mirroring GCR_CONFIG, and similarly a
new CPC_Cx_CONFIG register mirroring GCR_Cx_CONFIG.

In preparation for adjusting functions such as mips_cm_numcores(), which
have previously only needed to access the CM, to also access the CPC
this patch modifies the way we use the various CPS headers. Rather than
having users include asm/mips-cm.h or asm/mips-cpc.h individually we
instead have users include asm/mips-cps.h which in turn includes
asm/mips-cm.h & asm/mips-cpc.h. This means that users will gain access
to both CM & CPC registers by including one header, and most importantly
it makes asm/mips-cps.h an ideal location for helper functions which
need to access the various components of the CPS.

Subject: nfp: double free on error in probe

Both the nfp_net_pf_app_start() and the nfp_net_pci_probe() functions
call nfp_net_pf_app_stop_ctrl(pf) so there is a double free.  The free
should be done from the probe function because it's allocated there so
I have removed the call from nfp_net_pf_app_start().

Subject: net: bcmgenet: Use correct I/O accessors

The GENET driver currently uses __raw_{read,write}l which means
native I/O endian. This works correctly for an ARM LE kernel (default)
but fails miserably on an ARM BE (BE8) kernel where registers are kept
little endian, so replace uses with {read,write}l_relaxed here which is
what we want because this is all performance sensitive code.

Subject: drivers: net: xgene: Correct probe sequence handling

The phy is connected at early stage of probe but not properly
disconnected if error occurs.  This patch fixes the issue.

Also changing the return type of xgene_enet_check_phy_handle(),
since this function always returns success.

Subject: hwmon: (ftsteutates) constify i2c_device_id

i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

Subject: cpuidle: Eliminate the CPUIDLE_DRIVER_STATE_START symbol

On some architectures the first (index 0) idle state is a polling
one and it doesn't really save energy, so there is the
CPUIDLE_DRIVER_STATE_START symbol allowing some pieces of
cpuidle code to avoid using that state.

However, this makes the code rather hard to follow.  It is better
to explicitly avoid the polling state, so add a new cpuidle state
flag CPUIDLE_FLAG_POLLING to mark it and make the relevant code
check that flag for the first state instead of using the
CPUIDLE_DRIVER_STATE_START symbol.

In the ACPI processor driver that cannot always rely on the state
flags (like before the states table has been set up) define
a new internal symbol ACPI_IDLE_STATE_START equivalent to the
CPUIDLE_DRIVER_STATE_START one and drop the latter.

Subject: ACPI / APEI: Suppress message if HEST not present

According to the ACPI specification, firmware is not required to provide
the Hardware Error Source Table (HEST). When HEST is not present, the
following superfluous message is printed to the kernel boot log -

[    3.460067] GHES: HEST is not enabled!

Extend hest_disable variable to track whether the firmware provides this
table and if it is not present skip any log output. The existing
behaviour is preserved in all other cases.

Subject: libnvdimm, label: fix index block size calculation

The old calculation assumed that the label space was 128k and the label
size is 128. With v1.2 labels where the label size is 256 this
calculation will return zero. We are saved by the fact that the
nsindex_size is always pre-initialized from a previous 128 byte
assumption and we are lucky that the index sizes turn out the same.

Fix this going forward in case we start encountering different
geometries of label areas besides 128k.

Since the label size can change from one call to the next, drop the
caching of nsindex_size.

Subject: scsi: aacraid: Fix command send race condition

This fixes a potential race condition observed on Power systems.

Several places throughout the aacraid driver call aac_fib_send or
similar to send a command to the aacraid adapter, then check the return
code to determine if the command was actually sent to the adapter, then
update the phase field in the scsi command scratch pad area to track
that the firmware now owns this command.  However, there is nothing that
ensures that by the time the aac_fib_send function returns and we go to
write to the scsi command, that the command hasn't already completed and
the scsi command has been freed.  This was causing random crashes in the
TCP stack which was tracked down to be caused by memory that had been a
struct request + scsi_cmnd being now used for an skbuff. Memory
poisoning was enabled in the kernel to debug this which showed that the
last owner of the memory that had been freed was aacraid and that it was
a struct request.  The memory that was corrupted was the exact data
pattern of AAC_OWNER_FIRMWARE and it was at the same offset that aacraid
writes, which is scsicmd->SCp.phase. The patch below resolves this
issue.

Subject: scsi: Rework the code for caching Vital Product Data (VPD)

Introduce the scsi_get_vpd_buf() and scsi_update_vpd_page()
functions. The only functional change in this patch is that if updating
page 0x80 fails that it is attempted to update page 0x83.

Date: Tue, 29 Aug 2017 08:50:13 -0700
Subject: scsi: Rework handling of scsi_device.vpd_pg8[03]

Introduce struct scsi_vpd for the VPD page length, data and the RCU head
that will be used to free the VPD data. Use kfree_rcu() instead of
kfree() to free VPD data. Move the VPD buffer pointer check inside the
RCU read lock in the sysfs code. Only annotate pointers that are shared
across threads with __rcu. Use rcu_dereference() when dereferencing an
RCU pointer. This patch suppresses about twenty sparse complaints about
the vpd_pg8[03] pointers. This patch also fixes a race condition, namely
that updating of the VPD pointers and length variables in struct
scsi_device was not atomic with reference to the code reading these
variables. See also "Does the update code tolerate concurrent accesses?"
in Documentation/RCU/checklist.txt.

Fixes: commit 09e2b0b14690 ("scsi: rescan VPD attributes")

Subject: scsi: scsi_transport_sas: switch to bsg-lib for SMP passthrough

Simplify the SMP passthrough code by switching it to the generic bsg-lib
helpers that abstract away the details of the request code, and gets
drivers out of seeing struct scsi_request.

For the libsas host SMP code there is a small behavior difference in
that we now always clear the residual len for successful commands,
similar to the three other SMP handler implementations.  Given that
there is no partial command handling in the host SMP handler this should
not matter in practice.

[mkp: typos and checkpatch fixes]

Subject: rpmsg: glink: Introduce glink smem based transport

The glink protocol supports different types of transports (shared
memory). With the core protocol remaining the same, the way the
transport's memory is probed and accessed is different. So add support
for glink's smem based transports.

Adding a new smem transport register function and the fifo accessors for
the same.

Subject: rpmsg: glink: Add support for transport version negotiation

G-link supports a version number and feature flags for each transport.
A combination of the version number and feature flags enable/disable:

 (*) G-Link software updates for each edge
 (*) Individual features for each edge

Endpoints negotiate both the version and the supported flags when
the transport is opened and they cannot be changed after negotiation has
been completed.

Each full implementation of G-Link must support a minimum of the current
version, the previous version, and the base negotiation version called v0.

Subject: rpmsg: glink: Fix idr_lock from mutex to spinlock

The channel members lcids, rcids synchronised using the idr_lock is
accessed in both atomic/non-atomic contexts. The readers are not
currently synchronised.  That no correct, so add the readers as well
under the lock and use a spinlock.

Subject: rpmsg: glink: Add support for TX intents

Intents are nothing but pre-allocated buffers of appropriate size that
are allocated on the local side and communicated to the remote side and
the remote stores the list of intent ids that it is informed.

Later when remote side is intenting to send data, it picks up a right
intent (based on the size) and sends the data buffer and the intent id.
Local side receives the data and copies it to the local intent buffer.

The whole idea is to avoid stalls on the transport for allocating
memory, used for copy based transports.

When the remote request to allocate buffers using CMD_RX_INTENT_REQ, we
allocate buffers of requested size, store the buffer id locally and also
communicate the intent id to the remote.

Subject: rpmsg: glink: Use the local intents when receiving data

So previously on request from remote side, we allocated local intent
buffers and passed the ids to the remote. Now when we receive data
buffers from remote directed to that intent id, copy the data to the
corresponding preallocated intent buffer.

Subject: rpmsg: glink: Make RX FIFO peak accessor to take an offset

To fully read the received rx data from FIFO both the command and data
has to be read. Currently we read command, data separately and process
them. By adding an offset parameter to RX FIFO peak accessor, command
and data can be read together, simplifying things.  So introduce this.

Subject: rpmsg: glink: Add announce_create ops and preallocate intents

Preallocate local intent buffers and pass the intent ids to the remote.
This way there are some default intents available  for the remote to
start sending data without having to wait by sending intent requests. Do
this by adding the rpmsg announce_create ops, which gets called right
after the rpmsg device gets probed.

Just like we allocating and sending intent ids to remote, remote side
allocates and sends us the intents as well.  So save the intent ids and
use it later while sending data targeting the appropriate intents based
on the size.

While sending data, we search for suitable sized intent to map and
simply fail if a intent is not found. Instead request for a intent of
required size and wait till one is alloted.

Subject: USB: serial: option: add support for D-Link DWM-157 C1

This commit adds support (an ID, really) for D-Link DWM-157 hardware
version C1 USB modem to option driver.

According to manufacturer-provided Windows INF file the device has four
serial ports:
"D-Link HSPA+DataCard Diagnostics Interface" (interface 2; modem port),
"D-Link HSPA+DataCard NMEA Device" (interface 3),
"D-Link HSPA+DataCard Speech Port" (interface 4),
"D-Link HSPA+DataCard Debug Port" (interface 5).

Subject: iwlwifi: fix long debug print

There is a debug print that sometimes reaches over
110 chars, thus generating a warning in those cases.

Subject: iwlwifi: mvm: Avoid deferring non bufferable frames

Use bcast station for all non bufferable frames on AP and AD-HOC.

The host is no longer aware of STAs PS status because of buffer
station offload, so we can't rely on mac80211 to toggle on
IEEE80211_TX_CTL_NO_PS_BUFFER bit.

A possible issue with buffering such frames, beside the obvious spec
violation, is when a station disconnects while in PS but the AP isn't
aware of that. In such scenarios the AP won't be able to send probe
responses or auth frames so the STA won't be able to reconnect and
the AP will have a queue hang.

Subject: irqchip: mips-gic: SYNC after enabling GIC region

A SYNC is required between enabling the GIC region and actually trying
to use it, even if the first access is a read, otherwise its possible
depending on the timing (and in my case depending on the precise
alignment of certain kernel code) to hit CM bus errors on that first
access.

Add the SYNC straight after setting the GIC base.

[paul.burton@imgtec.com:
  Changes later in this series increase our likelihood of hitting this
  by reducing the amount of code that runs between enabling the GIC &
  accessing it.]

Subject: mmc: renesas-sdhi: add support for R-Car Gen3 SDHI DMAC

Add a new variant of the SDHI driver to support R-Car Gen3 with DMA via
on-chip bus mastering.  Since the DMAC is in a part of the SDHI module it
is not suitable to be used via DMA Engine.

Clearing of DM_CM_INFO1 after DMA thanks to Dirk Behme

Subject: mmc: omap_hsmmc: Reduce max_segs for reliability

Reduce max_segs to 64, a value that allows allocation of an entire
EDMA descriptor list within a single page - EDMA descriptors
are 40 bytes and the header is much larger. This avoids doing a
higher order GFP_ATOMIC allocation in edma_prep_slave_sg
when setting up a transfer which can potentially fail due to
fragmentation under heavy I/O load.

The current value of 1024 is unusually high in comparison to
other mmc host drivers which mostly use values of between 1
and 256. The EDMA driver at present splits lists above 20
segments in any case so reducing the size of lists we pass to
it shouldn't add much overhead.

platform_get_irq() returns an error code, but the mxcmmc driver
ignores it and always returns -EINVAL. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.

Print error message and propagate the return value of
platform_get_irq on failure.

Subject: mmc: tmio: fix CMD12 (STOP) handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I always anticipated this code to be not correct, but now I had a test
case to prove it. According to all documentation I have, setting the
TMIO_STOP_STP bit ever only worked during block transfers. This bit is
like manually enforcing an autocmd12 during a so far seamless transfer.
It does NOT work when the block transfer had errors. It also does NOT
work with any other cmd except block commands. For all those, CMD12 has
to be treated like any other command. So, basically, we could use this
bit only for mrq->data->stop cmds. But for these, we happily use the
autocmd12 feature using the TMIO_STOP_SEC bit. As a result, the above
bit is not useful for us and we need to treat CMD12 as a regular cmd
always. Just remove the special handling code. Note that the BSP
recognized this issue as well yet had a more cautious solution to the
problem [1]. Which is understandable but makes CMD12 handling even more
complicated.

Checked with a Renesas Salvator-X/M3-W which needed to send CMD12 when
retuning one of my SD cards.

Most registers need to wait until the command is completed, not
necessarily until the bus is free. At least, R-Car 2+ SoCs can signal
that via the CBSY bit, so let's use it there instead of SCLKDIVEN to
save a little bit of delay.

Subject: mmc: mxcmmc: check the return value of mxcmci_finish_data

We got a compile warning for mxcmmc,

drivers/mmc/host/mxcmmc.c: In function 'mxcmci_data_done':
drivers/mmc/host/mxcmmc.c:661:6: warning: variable 'data_error' set but
not used [-Wunused-but-set-variable]

The easiest method is to remove the data_error. But looking into
the code closely, I think we should check the return value of
mxcmci_finish_data as if it got data->error(the same as data_error),
we shouldn't try to read the response.

Subject: mmc: atmel-mci: remove unused sg_len variable

We got a warning:

drivers/mmc/host/atmel-mci.c:1086:15: warning: variable 'sg_len' set but
not used [-Wunused-but-set-variable]

Ideally we should check to see if sg_len is zero but looking
into the code closely, I didn't find any possible to do that as
atmci_start_request didn't even deploy any error handling for
its host->prepare_data hook. So even we return error value for iflags
like what other host drivers did, for instance, sdhci and dwmmc, it still
need some extra work to improve the code.

Just remove it to silent the warning, although it isn't perfect.

The setting of clocks and presets is currently done in probe only but
once deep PM support is added, it'll be needed in the resume function.

Let's create a function for this setting.

Subject: mmc: sdhci-of-at91: set clocks and presets after resume from deepest
 PM

This adds deepest (Backup+Self-Refresh) PM support to the ATMEL SAMA5D2
SoC's SDHCI controller.

When resuming from deepest state, it is required to restore preset
registers as the registers are lost since VDD core has been shut down
when entering deepest state on the SAMA5D2. The clocks need to be
reconfigured as well.

The other registers and init process are taken care of by the SDHCI
core.

Subject: mmc: atmel-mci: add missing of_node_put

for_each_child_of_node performs an of_node_get on each iteration, so a
break out the loop requires an of_node_put.

The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):

// <smpl>
@@
local idexpression n;
expression e,e1;
iterator name for_each_child_of_node;

 for_each_child_of_node(e1,n) {

?  break;

   ...
 }
... when != n

The intention of this check was to prevent the conflict between
hotplug and removing driver for whatever reason. Currently it
doesn't improve anything and the following rescan process could
still saftly perform the scan flow. So these code seems pointless
now and let's remove them.

Subject: mmc: core: always check the length of sglist with total data size

All the check within mmc_mrq_prep seems to be all-or-none
proposition, so it doesn't make sense to only check the
length of sglist only under the CONFIG_MMC_DEBUG context.
I'd prefer to always keep the check there unconditionally.

Subject: mmc: sdhci: remove CONFIG_MMC_DEBUG from the driver

sdhci uses CONFIG_MMC_DEBUG for showing ADMA descriptor
when occurring ADMA error. And it's also used to  dump the
registers whenever calling sdhci_add_host.

On one hand, I don't see any burden to always print the state
ADMA descriptor as it's rare and will help folks better understand
what was happening when seeing ADMA error.

On the other, folks may be interested in checking some registers
at probe time. So we remove the sdhci_dumpregs from __sdhci_add_host
and print some really useful registers in sdhci_setup_host.

Subject: mmc: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting

to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

Subject: mmc: renesas-sdhi: provide a whitelist for Gen3 SoC ES versions

Provide a whitelist for Gen3 SoC ES versions for both the SYS DMAC and
internal DMAC variants of the SDHI driver.  This is to allow drivers to
only initialise for Gen3 SoC ES versions for which they are the appropriate
DMAC implementation.  Currently internal DMAC is the appropriate
implementation for all supported Gen3 SoC ES versions.

Subject: clk: sunxi-ng: Add interface to query or configure MMC timing modes.

Starting with the A83T SoC, Allwinner introduced a new timing mode for
its MMC clocks. The new mode changes how the MMC controller sample and
output clocks are delayed to match chip and board specifics. There are
two controls for this, one on the CCU side controlling how the clocks
behave, and one in the MMC controller controlling what inputs to take
and how to route them.

In the old mode, the MMC clock had 2 child clocks providing the output
and sample clocks, which could be delayed by a number of clock cycles
measured from the MMC clock's parent.

With the new mode, the 2 delay clocks are no longer active. Instead,
the delays and associated controls are moved into the MMC controller.
The output of the MMC clock is also halved.

The difference in how things are wired between the modes means that the
clock controls and the MMC controls must match. To achieve this in a
clear, explicit way, we introduce two functions for the MMC driver to
use: one queries the hardware for the current mode set, and the other
allows the MMC driver to request a mode.

Subject: clk: sunxi-ng: Add MP_MMC clocks that support MMC timing modes
 switching

All of our MMC clocks are of the MP clock type. A few MMC clocks on some
SoCs, such as MMC2 on the A83T, support new/old timing mode switching.

>From a clock rate point of view, when the new timing mode is active. the
output clock rate is halved.

This patch adds a special wrapper class of clocks, MP_MMC, around the
generic MP type clocks. The rate related callbacks in ccu_mp_mmc_ops
for this class look at the timing mode bit and apply the /2 post-divider
when needed, before passing it through to the generic class ops,
ccu_mp_ops.

Subject: clk: sunxi-ng: a83t: Support new timing mode for mmc2 clock

The MMC2 clock supports a new timing mode. When the new mode is active,
the output clock rate is halved.

This patch sets the feature flag for the new timing mode, and adds
a pre-divider based on the mode bit.

Subject: mmc: sunxi: Support controllers that can use both old and new timings

On the SoCs that introduced the new timing mode for MMC controllers,
both the old (where the clock delays are set in the CCU) and new
(where the clock delays are set in the MMC controller) timing modes
are available, and we have to support them both. However there are
two bits that control which mode is active. One is in the CCU, the
other is in the MMC controller. The settings on both sides must be
the same, or nothing will work.

The sunxi-ng clock driver provides an API to query and set the
active timing mode. At probe time, we try to set the active mode
to the "new timing mode". If it succeeds, we can then use the MMC
controller in the new mode. If not, we fall back to the old mode.

Subject: mmc: sunxi: Support MMC DDR52 transfer mode with new timing mode

The MMC controller can support DDR52 transfers under the new timing
mode. According to the BSP kernel, the module clock has to be double
the card clock, regardless of the bus width. The default timings in
the hardware can be used.

This also reworks the code setting the internal divider, getting rid
of a extra conditional.

Subject: mmc: sunxi: Add support for A83T eMMC (MMC2)

The third MMC controller (MMC2) on the Allwinner A83T SoC is slightly
different. It supports a wider 8-bit bus, has a dedicated controllable
reset pin for eMMC, and a "new timing mode" which is supposed to deliver
better signals and thus better performance.

Add a compatible for this one to use the new timing mode not found in the
other controllers.

Subject: mmc: sunxi: Fix NULL pointer reference on clk_delays

Some SoCs do not support clk delays for MMC in the clock control unit.
These include the old controllers in A10/A10s/A13/R8, and the new eMMC
controller in A64. The config structure for these controllers do not
specify clk_delays, but the check for this was replaced in change
"mmc: sunxi: Support controllers that can use both old and new timings".

This patch adds back the check for clk_delays, and also adds comments
for both checks in sunxi_mmc_clk_set_phase().

The A83T MMC support code introduces the timings mode switch, however
such a switch doesn't exist on new SoCs with only new timings mode.

Only execute the switch if the SoC really have the timings mode switch,
to fix the regression shown on new timings mode only SoCs (A64, H5,

One issue was found on a removable high speed sd card with
runtime pm enabled.
When SD card is unplugged, it keep printing "Switching to 3.3V
signalling voltage failed".
And found below sequence triggers the error.

mmc_rescan
	-> mmc_sd_detect
		-> mmc_power_off  -- mmc->ios.vdd is updated to 0.
	-> mmc_claim_host
		-> sdhci_runtime_resume_host
			-> sdhci_start_signal_voltage_switch
				-> mmc_regulator_set_vqmmc
					-> mmc_ocrbitnum_to_vdd

When mmc_ocrbitnum_to_vdd is called, the mmc->ios.vdd is 0, so it
always return -EINVAL. The signal switch will always fail and
print out warning.
Ignore restoring the I/O state when runtime resume if MMC_POWER_OFF.

taac and nsac for SDHC(CSD version 2.0) are always fixed and
the software should use the recommended value for timeout. When
parsing the CSD, we sanely set them to zero for SDHC(CSD version
2.0), all the calculation for timeout_ns and timeout_clk is zero
as well. So what we actually want to limit here is either SDHC
case or unreasonable timeout reported by the cards. In principle
we should at least be able to remove the bogus check for the
mmc_card_blockaddr.

Subject: mmc: sdhci: add sdma_boundary member to struct sdhci_host

This patch adds sdma_boundary member to struct sdhci_host to give more
flexibility to drivers to control the sdma boundary buffer value and
also to fix issue on some sdhci controllers which are broken when
HOST SDMA Buffer Boundary is programmed in Block Size Register (0x04)
when using ADMA. Qualcomm sdhci controller is one of such type, writing
to this bits is un-supported.

Default value of sdma_boundary is set to SDHCI_DEFAULT_BOUNDARY_ARG.

Subject: mmc: sdhci-msm: set sdma_boundary to zero

Programming legacy HOST SDMA Buffer Boundary bits in Block Size Register
(0x04) is not supported in Qualcomm sdhci controllers. Writing to this
would cause the controller not to transfer last block in case block size
is 4 bytes or less.

This issue was noticed while testing sdio wlan card on Qcom DB410c board.

Subject: mmc: dw_mmc: move controller reset before driver init

This commit modifies dw_mci_probe(), it moves reset assertion before
drv_data->init(host)

Some driver needs to access controller registers in its .init() ops. So,
in order to make such access safe, we should do controller reset before
.init() being called.

Subject: mmc: dw_mmc: introduce timer for broken command transfer over scheme

Per the databook of designware mmc controller 2.70a, table 3-2, cmd
done interrupt should be fired as soon as the the cmd is sent via
cmd line. And the response timeout interrupt should be generated
unconditioinally as well if the controller doesn't receive the resp.
However that doesn't seem to meet the fact of rockchip specified Soc
platforms using dwmmc. We have continuously found the the cmd done or
response timeout interrupt missed somehow which took us a long time to
understand what was happening. Finally we narrow down the root to
the reconstruction of sample circuit for dwmmc IP introduced by
rockchip and the buggy design sweeps over all the existing rockchip
Socs using dwmmc disastrously.

It seems no way to work around this bug without the proper break-out
mechanism so that we seek for a parallel pair the same as the handling
for missing data response timeout, namely dto timer. Adding this cto
timer seems easily to handle this bug but it's hard to restrict the code
under the rockchip specified context. So after merging this patch, it
sets up the cto timer for all the platforms using dwmmc IP which isn't
ideal but at least we don't advertise new quirk here. Fortunately, no
obvious performance regression was found by test and the pre-existing
similar catch-all timer for sdhci has proved it's an acceptant way to
make the code as robust as possible.

Subject: mmc: sdhci-xenon: Add Xenon SDHCI specific system-level PM support

Add Xenon specific system-level suspend and resume support.
Especially during resume, re-configure Xenon specific registers
since registers setting will be lost in suspend if Xenon is power off.

Subject: mmc: renesas_sdhi: use extra flag for CBSY usage

There is one SDHI instance on Gen2 which does not have the CBSY bit.
So, turn CBSY usage into an extra flag and set it accordingly. This has
the additional advantage that we can also set it for other incarnations
later.

the width is 32 bit, even if the registers are only 16 bit apart.

Subject: mmc: sunxi: Fix clock rate passed to sunxi_mmc_clk_set_phase

sunxi_mmc_clk_set_phase expects the actual card clock rate to be passed
to it. When the internal divider code was reworked in change ("mmc: sunxi:
Support MMC DDR52 transfer mode with new timing mode"), this requirement
was missed, and the module clock rate was passed in instead. This broke 8
bit DDR MMC on old controllers, as the module clock rate is double the
card clock rate, for which we have no valid delay settings.

Fix this by applying the internal divider to the clock rate right after
we configure it in hardware.

Subject: mmc: core: Add mmc_retune_hold_now()

mmc_return_hold() / mmc_retune_release() are used around a group of
commands to prevent re-tuning between the commands. Re-tuning can still
happen before the first command. In some cases, re-tuning must be
prevented entirely. Add mmc_retune_hold_now() for that purpose. It is
added in preparation for CQE support where it will be used by CQE recovery.

Subject: MIPS: GIC: Introduce asm/mips-gic.h with accessor functions

This patch introduces a new header providing accessor functions for the
MIPS Global Interrupt Controller (GIC) mirroring those provided for the
other 2 components of the MIPS Coherent Processing System (CPS) - the
Coherence Manager (CM) & Cluster Power Controller (CPC).

This header makes use of the new standardised CPS accessor macros where
possible, but does require some custom accessors for cases where we have
either a bit or a register per interrupt.

A major advantage of this over the existing
include/linux/irqchip/mips-gic.h definitions is that code performing
accesses can become much simpler, for example this:

  gic_update_bits(GIC_REG(SHARED, GIC_SH_SET_TRIGGER) +
                  GIC_INTR_OFS(intr), 1ul << GIC_INTR_BIT(intr),
                  (unsigned long)trig << GIC_INTR_BIT(intr));

...can become simply:

  change_gic_trig(intr, trig);

The accessors handle 32 vs 64 bit in the same way as for CM & CPC code,
which means that GIC code will also not need to worry about the access
size in most cases. They are also accessible outside of
drivers/irqchip/irq-mips-gic.c which will allow for simplification in
the use of the non-interrupt portions of the GIC (eg. counters) which
currently require the interrupt controller driver to expose helper
functions for access.

This patch doesn't change any existing code over to use the new
accessors yet, since a wholesale change would be invasive & difficult to
review. Instead follow-on patches will convert code piecemeal to use
this new header. The one change to existing code is to rename gic_base
to mips_gic_base & make it global, in order to fit in with the naming
expected by the standardised CPS accessor macros.

Subject: mmc: sdhci-xenon: add set_power callback

Xenon sdh controller requests proper SD bus voltage select
bits programmed even with vmmc power supply. Any reserved
value(100b-000b) programmed in this field will lead to controller
ignore SD bus power bit and keep its value at zero.
Add set_power callback to handle this.

Subject: clocksource: mips-gic-timer: Use new GIC accessor functions

Switch from calling functions exported by the GIC interrupt controller
to using new accessors provided by asm/mips-gic.h. This will allow the
counter-handling functionality to be removed from the interrupt
controller driver, where it doesn't really belong, and also allow for
inlining of the accesses to the GIC.

Subject: efi: switch to use new generic UUID API

There are new types and helpers that are supposed to be used in new code.

As a preparation to get rid of legacy types and API functions do
the conversion here.

we'll have a mismatch to the MR page size that may cause a mapping error.
Update the MR page size to correspond to the core ctrl settings.

Subject: nvme-pci: use dma memory for the host memory buffer descriptors

The NVMe 1.3 specification says in section 5.21.1.13:

"After a successful completion of a Set Features enabling the host memory
 buffer, the host shall not write to the associated host memory region,
 buffer size, or descriptor list until the host memory buffer has been
 disabled."

While this doesn't state that the descriptor list must remain accessible
to the device it certainly implies it must remaing readable by the device.

So switch to a dma coherent allocation for the descriptor list just to be
safe - it's not like the cost for it matters compared to the actual
memory buffers.

Subject: nvme-fabrics: Convert nvmf_transports_mutex to an rwsem

The mutex protects against the list of transports changing while a
controller is being created, but using a plain old mutex means that it
also serializes controller creation.  This unnecessarily slows down
creating multiple controllers - for example for the RDMA transport,
creating a controller involves establishing one connection for every IO
queue, which involves even more network/software round trips, so the
delay can become significant.

The simplest way to fix this is to change the mutex to an rwsem and only
hold it for writing when the list is being mutated.  Since we can take
the rwsem for reading while creating a controller, we can create multiple
controllers in parallel.

Subject: mmc: core: Turn off CQE before sending commands

CQE needs to be off for the host controller to accept non-CQ commands. Turn
off the CQE before sending commands, and ensure it is off in any reset or
power management paths, or re-tuning.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Hosts supporting 8-bit bus are marked accordingly. If MMC_CAP_8_BIT_DATA
is not among host capabilities, 8BITBUS bit will never be set and it
is not cleared in case some non-SDHCI3 host uses it for something else.

Subject: mmc: test: reduce stack usage in mmc_test_nonblock_transfer

The new lockdep annotations for completions cause a warning in the
mmc test module, in a function that now has four 150 byte structures
on the stack:

drivers/mmc/core/mmc_test.c: In function 'mmc_test_nonblock_transfer.constprop':
drivers/mmc/core/mmc_test.c:892:1: error: the frame size of 1360 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

The mmc_test_ongoing_transfer function evidently had a similar problem,
and worked around it by using dynamic allocation.

This generalizes the approach used by mmc_test_ongoing_transfer() and
applies it to mmc_test_nonblock_transfer() as well.

Subject: mmc: debugfs: Move block debugfs into block module

If we don't have the block layer enabled, we do not present card
status and extcsd in the debugfs.

Debugfs is not ABI, and maintaining files of no relevance for
non-block devices comes at a high maintenance cost if we shall
support it with the block layer compiled out.

The debugfs entries suffer from all the same starvation
issues as the other userspace things, under e.g. a heavy
dd operation.

The expected number of debugfs users utilizing these two
debugfs files is already low as there is an ioctl() to get the
same information using the mmc-tools, and of these few users
the expected number of people using it on SDIO or combo cards
are expected to be zero.

It is therefore logical to move this over to the block layer
when it is enabled, using the new custom requests and issue
it using the block request queue.

On the other hand it moves some debugfs code from debugfs.c
and into block.c.

Tested during heavy dd load by cat:in the status file.

Subject: mmc: block: Move duplicate check

mmc_blk_ioctl() calls either mmc_blk_ioctl_cmd() or
mmc_blk_ioctl_multi_cmd() and each of these make the same
check. Factor it into a new helper function, call it on
both branches of the switch() statement and save a chunk
of duplicate code.

Subject: mmc: block: Reparametrize mmc_blk_ioctl_[multi]_cmd()

Instead of passing a block device to
mmc_blk_ioctl[_multi]_cmd(), let's pass struct mmc_blk_data()
so we operate ioctl()s on the MMC block device representation
rather than the vanilla block device.

This saves a little duplicated code and makes it possible to
issue ioctl()s not targeted for a specific block device but
rather for a specific partition/area.

Subject: mmc: sdhci: Add quirk to indicate MMC_RSP_136 has CRC

TI's implementation of sdhci controller used in DRA7 SoC's has
CRC in responses with length 136 bits. Add quirk to indicate
the controller has CRC in MMC_RSP_136. If this quirk is
set sdhci library shouldn't shift the response present in
SDHCI_RESPONSE register.

Subject: mmc: sdhci-cadence: add suspend / resume support

Currently, the probe function initializes the PHY, but PHY settings
are lost during the sleep state.  Restore the PHY registers when
resuming.

To facilitate this, split sdhci_cdns_phy_init() into the DT parse
part and PHY update part so that the latter can be invoked from the
resume hook.

Subject: mmc: sdhci-pxav2: switch to managed clk and sdhci_pltfm_unregister()

The difference between sdhci_pxav2_remove() and sdhci_pltfm_unregister()
is clk_put().  It will go away by using the managed resource clk, then
sdhci_pltfm_unregister() can be reused.

Also, rename the jump labels to say what the goto does. (Coding style
suggested by Documentation/process/coding-style.rst)

Subject: mmc: sdhci: enable/disable the clock in sdhci_pltfm_suspend/resume

This commit provides similar cleanups as commit 83eacdfa2529 ("mmc:
sdhci: disable the clock in sdhci_pltfm_unregister()") did for
unregister hooks.

sdhci-brcmstb.c and sdhci-sirf.c implement their own suspend/resume
hooks to handle pltfm_host->clk.  Move clock handling to sdhci_pltfm.c
so that the drivers can reuse sdhci_pltfm_pmops.

The following drivers did not previously touch pltfm_host->clk during
suspend/resume, but now do:
  - sdhci-bcm-kona.c
  - sdhci-dove.c
  - sdhci-iproc.c
  - sdhci-pxav2.c
  - sdhci-tegra.c
  - sdhci-xenon.c

Subject: mmc: block: cast a informative log for no devidx available

The intention for this patch is to help folks debug the failure
like this:

dwmmc_rockchip fe320000.dwmmc: IDMAC supports 32-bit address mode.
dwmmc_rockchip fe320000.dwmmc: Using internal DMA controller.
dwmmc_rockchip fe320000.dwmmc: Version ID is 270a
dwmmc_rockchip fe320000.dwmmc: DW MMC controller at irq 28,32 bit
host data width,256 deep fifo
dwmmc_rockchip fe320000.dwmmc: Got CD GPIO
mmc_host mmc0: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual
400000HZ div = 0)
mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 50000000Hz,
actual 50000000HZ div = 0)
mmc0: new high speed SDHC card at address 0007
mmcblk: probe of mmc0:0007 failed with error -28

The reason may be some buggy userspace daemon miss the disk remove
uevent sometimes so it would finally make the SD card not work.
So from the dmesg it only shows a errno of -28 but still don't understand
what happened.

For quick reproduce this, we could set max_devices to 8 and run

for i in $(seq 1 9); do
  echo "========================" $i
  echo fe320000.dwmmc > /sys/bus/platform/drivers/dwmmc_rockchip/unbind
  sleep .5
  echo fe320000.dwmmc > /sys/bus/platform/drivers/dwmmc_rockchip/bind
  sleep .5
  mount -t vfat /dev/mmcblk0 /mnt
  sleep .5
done

Another possible reason would be the device has more partitions than
what we support, so that they have to increase their max_devices.

Subject: mmc: meson-gx: initialize sane clk default before clock register

On boot, the clock divider value is 0 which is a weird unsupported value.
For example, accessing the cfg register with this value set would crash
the SoC.

Previous change removed 0 as possible value for CCF but forgot to properly
initialize the register before registering the clock. This leads to the
CCF finding an illegal value, which it complains about.

Initialize the register properly in a standalone patch so the fix can be
picked up if necessary. The change this fixed is: "mmc: meson-gx: remove
CLK_DIVIDER_ALLOW_ZERO clock flag".

Subject: mmc: meson-gx: rework clock init function

Thanks to devm, carrying the clock structure around after init is not
necessary. Rework the function to remove these from the controller host
data.

Finally, set initial mmc clock rate before enabling it, simplifying the
exit condition.

Subject: mmc: meson-gx: work around clk-stop issue

It seems that the mmc clock is also used and required, somehow, by
the controller itself.

It is shown during init, when writing to CFG while the divider is set
to 0 will crash the SoC. During a voltage switch, the controller may
crash and the card may then fail to exit busy state if the clock is
stopped.

To avoid this, it is best to keep the clock running for the controller,
except during rate change. However, we still need to be able to gate
the clock out of the SoC. Let's use the pinmux for this, and fallback
to gpio mode (pulled-down) when we need to gate the clock

Subject: mmc: meson-gx: use CCF to handle the clock phases

Several phases can be controlled on the meson-gx controller, the core, tx
and rx clock phase. The tx and rx uses delays to allow  more fine grained
setting of the phase. To properly compute the phase using delays,
accessing the clock rate is necessary.

Instead of ad-hoc functions, use the common clock framework to set the
clock phases (and access the clock rate while doing it).

Subject: mmc: meson-gx: implement voltage switch callback

Implement voltage switch callback (shamelessly copied from sunxi mmc
driver). This allow, with the appropriate tuning function, to use
SD ultra high speed modes.

Subject: mmc: meson-gx: change default tx phase

Initial default tx phase was set to 0 while the datasheet recommends 270.
Some cards fails to initialize with this setting and eMMC mode DDR52 does
not work.

Changing this setting to 270 fixes these issues, without any regression
so far

Subject: mmc: meson-gx: rework tuning function

Rework tuning function of the rx phase. Now that the phase can be
more precisely set using CCF, test more phase setting and find the
largest working window. Then the tuning selected is the one at the
center of the window.

This rework allows to use new modes, such as UHS SDR50

Subject: mmc: sunxi: Reset the device at probe time

We might be into some troubles if the bootloader misconfigured the MMC
controller.

We currently only de-assert the reset line at probe time, which means that
if the device was already out of reset, we're going to keep whatever state
was set already.

Switch to a reset instead of the deassert to have a device in a pristine
state when we start operating.

this has just 2 helper functions specific to qcom, and used directly by

This would also fix issues arrising due to Kconfig combinations between

Subject: iommu/ipmmu-vmsa: Rereserving a free context before setting up a
 pagetable

Reserving a free context is both quicker and more likely to fail
(due to limited hardware resources) than setting up a pagetable.
What is more the pagetable init/cleanup code could require
the context to be set up.

Subject: PCI: mediatek: Explicitly request exclusive reset control

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls to
explicitly state whether the driver needs exclusive or shared reset control
behavior. Convert all drivers requesting exclusive resets to the explicit
API call so the temporary transition helpers can be removed.

No functional changes.

Rename "port->index" to "port->slot" since the ports are hardwired at
PCI_SLOT.  Also rename "mtk_pcie_parse_ports()" to "mtk_pcie_parse_port()"
since it parses one port each time.

Subject: PCI: mediatek: Add a structure to abstract the controller generations

Introduce a structure "mtk_pcie_soc" to abstract the differences between
controller generations, and the .startup() hook is used to encapsulate some
SoC-dependent related setting.  In doing so, the common code which will be
reused by future chips.

Subject: PCI: mediatek: Switch to use platform_get_resource_byname()

This is a transitional patch.  We currently use platfarm_get_resource() for
retrieving the IOMEM resources, but there might be some chips don't have
subsys/shared registers part, which depends on platform design, and these
will be introduced in further patches.

Switch this function to use the platform_get_resource_byname() so that the
binding can be agnostic of the resource order.

Subject: PCI: mediatek: Add controller support for MT2712 and MT7622

MT2712 and MT7622 using a new IP block of Gen2 controller which has two
root ports and shares the same probing flow with MT2701/MT7623.

Both MT2712 and MT7622 have the same per-port control registers, but
there are slight differences between them:

  - MT7622 has more clocks than MT2712.

  - MT7622 has shared control registers which are used to enable LTSSM and
    ASPM while MT2712 does not.

Add host controller support for MT2712/MT7622.

Subject: PCI: mediatek: Use bus->sysdata to get host private data

75983c6d1f38 ("PCI: mediatek: Add controller support for MT2712 and
MT7622") has put the mtk_pcie * into bus->sysdata.  Take advantage of that
to get the private data and simplify the code.

Subject: PCI: mediatek: Add MSI support for MT2712 and MT7622

MT2712 and MT7622's PCIe host controller support MSI, but only 32-bit MSI
addresses are supported. It connects to GIC with the same IRQ number as the
INTx IRQ, so it shares the same IRQ with INTx IRQ.

Add MSI support for MT2712 and MT7622.

[bhelgaas: changes to follow rcar & tegra: rename to mtk_pcie_msi_alloc(),
add mtk_pcie_msi_free(), free hwirq if irq_create_mapping() fails, call
irq_dispose_mapping() from mtk_msi_teardown_irq()]

The TI LM5066I hotswap controller is a more accurate version of the
LM5066 device already supported. It has different measurement conversion
coefficients than the LM5066, so it needs to be recognized as a
different device.

Subject: drbd: remove BIOSET_NEED_RESCUER flag from drbd_{md_,}io_bio_set

Careful analysis shows that this flag is not needed.

The RESCUER flag is only needed when a make_request_fn might:
 - allocate a bio from the bioset
 - submit it with generic_make_request() or similar
 - allocate another bio from the bioset

The second allocation can block until the first bio is processed, so
a rescuer is needed to ensure the first bio does get processed.  With
a rescuer it will only get processed when the make_request_fn completes.

In drbd, allocations from drbd_io_bio_set happen from drbd_new_req()
or w_restart_disk_io() which is only called to handle
RESTART_FROZEN_DISK_IO.

In former is called precisely once from the make_request_fn.
The later is never called by within the make_request_fn.

So there cannot be two allocations in the same call to the
make_request_fn, so a rescuer is not needed.

Allocations from drbd_md_io_bio_set are used for IO to the bitmap and
the activity log.  There are only accessed from worker threads and
workqueues, never directly from make_request_fn.
Again, the rescuer isn't needed.

Subject: IB/core: Add a generic way to execute an operation on a uobject

The ioctl infrastructure treats all user-objects in the same manner.
It gets objects ids from the user-space and by using the object type
and type attributes mentioned in the object specification, it executes
this required method. Passing an object id from the user-space as
an attribute is carried out in three stages. The first is carried out
before the actual handler and the last is carried out afterwards.

The different supported operations are read, write, destroy and create.
In the first stage, the former three actions just fetches the object
from the repository (by using its id) and locks it. The last action
allocates a new uobject. Afterwards, the second stage is carried out
when the handler itself carries out the required modification of the
object. The last stage is carried out after the handler finishes and
commits the result. The former two operations just unlock the object.
Destroy calls the "free object" operation, taking into account the
object's type and releases the uobject as well. Creation just adds the
new uobject to the repository, making the object visible to the
application.

In order to abstract these details from the ioctl infrastructure
layer, we add uverbs_get_uobject_from_context and
uverbs_finalize_object functions which corresponds to the first
and last stages respectively.

Subject: IB/core: Add support to finalize objects in one transaction

The new ioctl based infrastructure either commits or rollbacks
all objects of the method as one transaction. In order to do
that, we introduce a notion of dealing with a collection of
objects that are related to a specific method.

This also requires adding a notion of a method and attribute.
A method contains a hash of attributes, where each bucket
contains several attributes. The attributes are hashed according
to their namespace which resides in the four upper bits of the id.

For example, an object could be a CQ, which has an action of CREATE_CQ.
This action has multiple attributes. For example, the CQ's new handle
and the comp_channel. Each layer in this hierarchy - objects, methods
and attributes is split into namespaces. The basic example for that is
one namespace representing the default entities and another one
representing the driver specific entities.

When declaring these methods and attributes, we actually declare
their specifications. When a method is executed, we actually
allocates some space to hold auxiliary information. This auxiliary
information contains meta-data about the required objects, such
as pointers to their type information, pointers to the uobjects
themselves (if exist), etc.
The specification, along with the auxiliary information we allocated
and filled is given to the finalize_objects function.

Subject: power: supply: bq24190_charger: Export 5V boost converter as
 regulator

Register the 5V boost converter as a regulator named "usb_otg_vbus".

This commit also adds support for bq24190_platform_data, through which
non device-tree platforms can pass the regulator_init_data (containing
mappings for the consumer amongst other things).

Subject: power: supply: bq24190_charger: Get input_current_limit from our
 supplier

On some devices the USB Type-C port power (USB PD 2.0) negotiation is
done by a separate port-controller IC, while the current limit is
controlled through another (charger) IC.

It has been decided to model this by modelling the external Type-C
power brick (adapter/charger) as a power-supply class device which
supplies the charger-IC, with its voltage-now and current-max representing
the negotiated voltage and max current draw.

This commit adds support for this to the bq24190_charger driver by adding
an external_power_changed callback and calling
power_supply_set_input_current_limit_from_supplier from this callback.
This callback will only get called if the bq24190 has a parent-supply.

Note this replaces the functionality to get the current-limit from an
extcon device, which will be removed in a follow-up commit.

happens when a KVM domain with assigned devices is
destroyed, this causes thousands of unnecessary TLB flushes
in the IOMMU hardware because the unmap call-back runs for
every unmapped physical page.

With the TLB Flush Interface and the new iommu_unmap_fast()
function introduced here the need to clean the hardware TLBs
is removed from the unmapping code-path. Users of
iommu_unmap_fast() have to explicitly call the TLB-Flush
functions to sync the page-table changes to the hardware.

Three functions for TLB-Flushes are introduced:

	* iommu_flush_tlb_all() - Flushes all TLB entries
	                          associated with that
				  domain. TLBs entries are
				  flushed when this function
				  returns.

	* iommu_tlb_range_add() - This will add a given
				  range to the flush queue
				  for this domain.

	* iommu_tlb_sync() - Flushes all queued ranges from
			     the hardware TLBs. Returns when
			     the flush is finished.

The semantic of this interface is intentionally similar to
the iommu_gather_ops from the io-pgtable code.

Subject: dax: introduce a fs_dax_get_by_bdev() helper

Add a helper that can replace the following common pattern:

	if (blk_queue_dax(bdev->bd_queue))
		fs_dax_get_by_host(bdev->bd_disk->disk_name);

This will be used to move dax_device lookup from iomap-operation time to
fs-mount time.

Subject: net: ti: cpsw-common: dont print error if ti_cm_get_macid() fails

It is quite common for ti_cm_get_macid() to fail on some of the
platforms it is invoked on. They include any platform where
mac address is not part of SoC register space.

On these platforms, mac address is read and populated in
device-tree by bootloader. An example is TI DA850.

Downgrade the severity of message to "information", so it does
not spam logs when 'quiet' boot is desired.

Subject: staging: irda: fix init level for irda core

When moving the IRDA code out of net/ into drivers/staging/irda/net, the
link order changes when IRDA is built into the kernel.  That causes a
kernel crash at boot time as netfilter isn't initialized yet.

To fix this, move the init call level of the irda core to be
device_initcall() as the link order keeps this being initialized at the
correct time.

Subject: net/mlx5e: Fix DCB_CAP_ATTR_DCBX capability for DCBNL getcap.

Current code doesn't report DCB_CAP_DCBX_HOST capability when query
through getcap. User space lldptool expects capability to have HOST mode
set when it wants to configure DCBX CEE mode. In absence of HOST mode
capability, lldptool fails to switch to CEE mode.

This fix returns DCB_CAP_DCBX_HOST capability when port's DCBX
controlled mode is under software control.

Support for ISSI version 0 was recently broken as the arm_srq_cmd

Subject: net/mlx5: Skip mlx5_unload_one if mlx5_load_one fails

There is an issue where the firmware fails during mlx5_load_one,
the health_care timer detects the issue and schedules a health_care call.
Then the mlx5_load_one detects the issue, cleans up and quits. Then
the health_care starts and calls mlx5_unload_one to clean up the resources
that no longer exist and causes kernel panic.

The root cause is that the bit MLX5_INTERFACE_STATE_DOWN is not set
after mlx5_load_one fails. The solution is removing the bit
MLX5_INTERFACE_STATE_DOWN and quit mlx5_unload_one if the
bit MLX5_INTERFACE_STATE_UP is not set. The bit MLX5_INTERFACE_STATE_DOWN
is redundant and we can use MLX5_INTERFACE_STATE_UP instead.

Currently, increasing the number of combined channels is changing
the RSS spread to use the new created channels.
Prevent the RSS spread change in case the user explicitly declare it,
to avoid overriding user configuration.

Tested:
when RSS default:

# ethtool -L ens8 combined 4
RSS spread will change and point to 4 channels.

# ethtool -X ens8 equal 4
# ethtool -L ens8 combined 6
RSS will not change after increasing the number of the channels.

Subject: net/mlx5e: Properly resolve TC offloaded ipv6 vxlan tunnel source
 address

Currently if vxlan tunnel ipv6 src isn't supplied the driver fails to
resolve it as part of the route lookup. The resulting encap header
is left with a zeroed out ipv6 src address so the packets are sent
with this src ip.

Use an appropriate route lookup API that also resolves the source
ipv6 address if it's not supplied.

Subject: net/mlx5: E-Switch, Unload the representors in the correct order

When changing from switchdev to legacy mode, all the representor port
devices (uplink nic and reps) are cleaned up. Part of this cleaning
process is removing the neigh entries and the hash table containing them.
However, a representor neigh entry might be linked to the uplink port
hash table and if the uplink nic is cleaned first the cleaning of the
representor will end up in null deref.
Fix that by unloading the representors in the opposite order of load.

+1. Introduction
+
+rmnet driver is used for supporting the Multiplexing and aggregation
+Protocol (MAP). This protocol is used by all recent chipsets using Qualcomm
+Technologies, Inc. modems.
+
+This driver can be used to register onto any physical network device in
+IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.
+
+Multiplexing allows for creation of logical netdevices (rmnet devices) to
+handle multiple private data networks (PDN) like a default internet, tethering,
+multimedia messaging service (MMS) or IP media subsystem (IMS). Hardware sends
+packets with MAP headers to rmnet. Based on the multiplexer id, rmnet
+routes to the appropriate PDN after removing the MAP header.
+
+Aggregation is required to achieve high data rates. This involves hardware
+sending aggregated bunch of MAP frames. rmnet driver will de-aggregate
+these MAP frames and send them to appropriate PDN's.
+
+2. Packet format
+
+a. MAP packet (data / control)
+
+MAP header has the same endianness of the IP packet.
+
+Packet format -
+
+Bit             0             1           2-7      8 - 15           16 - 31
+Function   Command / Data   Reserved     Pad   Multiplexer ID    Payload length
+Bit            32 - x
+Function     Raw  Bytes
+
+Command (1)/ Data (0) bit value is to indicate if the packet is a MAP command
+or data packet. Control packet is used for transport level flow control. Data
+packets are standard IP packets.
+
+Reserved bits are usually zeroed out and to be ignored by receiver.
+
+Padding is number of bytes to be added for 4 byte alignment if required by
+hardware.
+
+Multiplexer ID is to indicate the PDN on which data has to be sent.
+
+Payload length includes the padding length but does not include MAP header
+length.
+
+b. MAP packet (command specific)
+
+Bit             0             1           2-7      8 - 15           16 - 31
+Function   Command         Reserved     Pad   Multiplexer ID    Payload length
+Bit          32 - 39        40 - 45    46 - 47       48 - 63
+Function   Command name    Reserved   Command Type   Reserved
+Bit          64 - 95
+Function   Transaction ID
+Bit          96 - 127
+Function   Command data
+
+Command 1 indicates disabling flow while 2 is enabling flow
+
+Command types -
+0 for MAP command request
+1 is to acknowledge the receipt of a command
+2 is for unsupported commands
+3 is for error during processing of commands
+
+c. Aggregation
+
+Aggregation is multiple MAP packets (can be data or command) delivered to
+rmnet in a single linear skb. rmnet will process the individual
+packets and either ACK the MAP command or deliver the IP packet to the
+network stack as needed
+
+MAP header|IP Packet|Optional padding|MAP header|IP Packet|Optional padding....
+MAP header|IP Packet|Optional padding|MAP header|Command Packet|Optional pad...
+
+3. Userspace configuration
+
+rmnet userspace configuration is done through netlink library librmnetctl
+and command line utility rmnetcli. Utility is hosted in codeaurora forum git.
+The driver uses rtnl_link_ops for communication.

Subject: drm/i915: Quietly cancel FBC activation if CRTC is turned off before
 worker

Since we use a worker to enable FBC on the CRTC, it is possible for the
CRTC to be switched off before we run. In this case, the CRTC will not
allow us to wait upon a vblank, so remove the DRM_ERROR as this is very
much expected.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102410

Subject: drm/i915: Recreate vmapping even when the object is pinned

Sometimes we know we are the only user of the bo, but since we take a
protective pin_pages early on, an attempt to change the vmap on the
object is denied because it is busy. i915_gem_object_pin_map() cannot
tell from our single pin_count if the operation is safe. Instead we must
pass that information down from the caller in the manner of
I915_MAP_OVERRIDE.

This issue has existed from the introduction of the mapping, but was
never noticed as the only place where this conflict might happen is for
cached kernel buffers (such as allocated by i915_gem_batch_pool_get()).
Until recently there was only a single user (the cmdparser) so no
conflicts ever occurred. However, we now use it to allocate batches for
different operations (using MAP_WC on !llc for writes) in addition to the
existing shadow batch (using MAP_WB for reads).

We could either keep both mappings cached, or use a different write
mechanism if we detect a MAP_WB already exists (i.e. clflush
afterwards), but as we haven't seen this issue in the wild (it requires
hitting the GPU reloc path in addition to the cmdparser) for simplicity
just allow the mappings to be recreated.

v2: Include the i915_MAP_OVERRIDE bit in the enum so the compiler knows
about all the valid values.

Subject: drm/i915: Always wake the device to flush the GTT

Since we hold the device wakeref when writing through the GTT (otherwise
the writes would fail), we presumed that before the device sleeps those
writes would naturally be flushed and that we wouldn't need our mmio
read trick. However, that presumption seems false and a sleepy bxt seems
to require us to always manually flush the GTT writes prior to direct
access.

Subject: drm/i915: Skip fence alignemnt check for the CCS plane
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The CCS won't have the same stride as the main surface anyway so trying
to guard against the fence stride not matching the CCS stride is
not sensible. Just skip the fence vs. fb alignment check for the aux
plane.

Subject: drm/i915: Ignore duplicate VMA stored within the per-object handle
 LUT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

By using drm_gem_flink/drm_gem_open on an object using the same fd, it
is possible for a client to create multiple handles pointing to the same
object (tied to the same contexts and VMA), as exemplified by
igt::gem_handle_to_libdrm_bo(). Since this duplication has been possible
since forever, we cannot assume that the handle:(fpriv, object) is
unique and so must handle the multiple users of a single VMA.

v2: Added commentary noise.

Subject: vfio: fix noiommu vfio_iommu_group_get reference count

In vfio_iommu_group_get() we want to increase the reference
count of the iommu group.

In noiommu case, the group does not exist and is allocated.
iommu_group_add_device() increases the group ref count. However we
then call iommu_group_put() which decrements it.

This leads to a "refcount_t: underflow WARN_ON".

Only decrement the ref count in case of iommu_group_add_device
failure.

Subject: vfio: Stall vfio_del_group_dev() for container group detach

When the user unbinds the last device of a group from a vfio bus
driver, the devices within that group should be available for other
purposes.  We currently have a race that makes this generally, but
not always true.  The device can be unbound from the vfio bus driver,
but remaining IOMMU context of the group attached to the container
can result in errors as the next driver configures DMA for the device.

Wait for the group to be detached from the IOMMU backend before
allowing the bus driver remove callback to complete.

Subject: PCI: vmd: Remove IRQ affinity so we can allocate more IRQs

VMD hardware has to share its vectors among child devices in its PCI
domain so we should allocate as many as possible rather than just ones
that can be affinitized.

pci_alloc_irq_vectors_affinity() limits the number of affinitized IRQs to
the number of present CPUs (see irq_calc_affinity_vectors()).  But we'd
prefer to have more vectors, even if they aren't distributed across the
CPUs, so use pci_alloc_irq_vectors() instead.

Subject: iommu/vt-d: Prevent VMD child devices from being remapping targets

VMD child devices must use the VMD endpoint's ID as the requester.  Because
of this, there needs to be a way to link the parent VMD endpoint's IOMMU
group and associated mappings to the VMD child devices such that attaching
and detaching child devices modify the endpoint's mappings, while
preventing early detaching on a singular device removal or unbinding.

The reassignment of individual VMD child devices devices to VMs is outside
the scope of VMD, but may be implemented in the future. For now it is best
to prevent any such attempts.

Prevent VMD child devices from returning an IOMMU, which prevents it from
exposing an iommu_group sysfs directory and allowing subsequent binding by
userspace-access drivers such as VFIO.

Subject: phy: add the mvebu cp110 comphy driver

On the CP110 unit, which can be found on various Marvell platforms such
as the 7k and 8k (currently), a comphy (common PHYs) hardware block can
be found. This block provides a number of PHYs which can be used in
various modes by other controllers (network, SATA ...). These common
PHYs must be configured for the controllers using them to work correctly
either at boot time, or when the system runs to switch the mode used.
This patch adds a driver for this comphy hardware block, providing
callbacks for the its PHYs so that consumers can configure the modes
used.

As of this commit, two modes are supported by the comphy driver: sgmii
and 10gkr.

Subject: net: mvpp2: initialize the comphy

On some platforms, the comphy is between the MAC GoP and the PHYs. The
mvpp2 driver currently relies on the firmware/bootloader to configure
the comphy. As a comphy driver was added to the generic PHY framework,
this patch uses it in the mvpp2 driver to configure the comphy at boot
time to avoid relying on the bootloader.

Subject: net: mvpp2: improve the link management function

When the link status changes, the phylib calls the link_event function
in the mvpp2 driver. Before this patch only the egress/ingress transmit
was enabled/disabled. This patch adds more functionality to the link
status management code by enabling/disabling the port per-cpu
interrupts, and the port itself. The queues are now stopped as well, and
the netif carrier helpers are called.

Subject: net: mvpp2: do not set GMAC autoneg when using XLG MAC

When using the XLG MAC, it does not make sense to force the GMAC autoneg
parameters. This patch adds checks to only set the GMAC autoneg
parameters when needed (i.e. when not using the XLG MAC).

Subject: net: mvpp2: dynamic reconfiguration of the comphy/GoP/MAC

This patch adds logic to reconfigure the comphy/GoP/MAC when the link
state is updated at runtime. This is very useful on boards where many
link speed are supported: depending on what is negotiated the PPv2
driver will automatically reconfigures the link between the PHY and the
MAC.

Subject: net/mlx5e: Use IP version matching to classify IP traffic

This change adds the ability for flow steering to classify IPv4/6
packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP
packets and hit IPv4/6 classification steering rules.

Since IP packets with MPLS tag header have MPLS ethertype, they
missed the IPv4/6 ethertype rule and ended up hitting the default
filter forwarding all the packets to the same single RQ (No RSS).

Since our device is able to look past the MPLS tag and identify the
next protocol we introduce this solution which replaces ethertype
matching by the device's capability to perform IP version
identification and matching in order to distinguish between IPv4 and
IPv6.
Therefore, when driver is performing flow steering configuration on the
device it will use IP version matching in IP classified rules instead
of ethertype matching which will cause relevant MPLS tagged packets to
hit this rule as well.

If the device doesn't support IP version matching the driver will fall back
to use legacy ethertype matching in the steering as before.

When a GRE tunneled packet is received, the TTC flow table will match
the new IPv4/6->GRE rules which will forward it to the inner TTC table.
The inner TTC is similar to its counterpart outer TTC table, but
matching the inner packet headers instead of the outer ones (and does
not include the new IPv4/6->GRE rules).
The new rules will not add steering hops since they are added to an
already existing flow group which will be matched regardless of this
patch. Non GRE traffic will not be affected.

The inner flow table will forward the packet to inner indirect TIRs
which hash the inner packet and thus result in RSS for the tunneled
packets.

Testing 8 TCP streams bandwidth over GRE:
System: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
NIC: Mellanox Technologies MT28800 Family [ConnectX-5 Ex]
Before: 21.3 Gbps (Single RQ)
Now   : 90.5 Gbps (RSS spread on 8 RQs)

Subject: xen-netfront: be more drop monitor friendly

xennet_start_xmit() might copy skb with inappropriate layout
into a fresh one.

Old skb is freed, and at this point it is not a drop, but
a consume. New skb will then be either consumed or dropped.

Subject: remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver

Provide a basic driver to control Cortex M4 co-processor found
on NXP i.MX7D and i.MX6SX.
Currently it is able to resolve addresses between M4 and main CPU,
start and stop the co-processor. Other functionality is not provided
or test.

This driver was tested on NXP i.MX7D and expected to work on
i.MX6SX as well.

Subject: remoteproc: Stop subdevices in reverse order

Subdevices might depend on earlier registered subdevices for
communication purposes, as such they should be stopped in reverse order
so that said communication channel is removed after the dependent
subdevice is stopped.

Subject: Revert "net: phy: Correctly process PHY_HALTED in phy_stop_machine()"

This reverts commit 7ad813f208533cebfcc32d3d7474dc1677d1b09a ("net: phy:
Correctly process PHY_HALTED in phy_stop_machine()") because it is
creating the possibility for a NULL pointer dereference.

David Daney provide the following call trace and diagram of events:

When ndo_stop() is called we call:

 phy_disconnect()
    +---> phy_stop_interrupts() implies: phydev->irq = PHY_POLL;
    +---> phy_stop_machine()
    |      +---> phy_state_machine()
    |              +----> queue_delayed_work(): Work queued.
    +--->phy_detach() implies: phydev->attached_dev = NULL;

Now at a later time the queued work does:

 phy_state_machine()
    +---->netif_carrier_off(phydev->attached_dev): Oh no! It is NULL:

The original motivation for this change originated from Marc Gonzales
indicating that his network driver did not have its adjust_link callback
executing with phydev->link = 0 while he was expecting it.

PHYLIB has never made any such guarantees ever because phy_stop() merely just
tells the workqueue to move into PHY_HALTED state which will happen
asynchronously.

Subject: scsi: storvsc: fix memory leak on ring buffer busy

When storvsc is sending I/O to Hyper-v, it may allocate a bigger buffer
descriptor for large data payload that can't fit into a pre-allocated
buffer descriptor. This bigger buffer is freed on return path.

If I/O request to Hyper-v fails due to ring buffer busy, the storvsc
allocated buffer descriptor should also be freed.

[mkp: applied by hand]

Subject: scsi: aacraid: report -ENOMEM to upper layer from
 aac_convert_sgraw2()

aac_convert_sgraw2() kmalloc memory and return -1 on error, which should
be -ENOMEM. However, nobody is checking return value, so with this
change, -ENOMEM is propagated to upper layer.

Subject: scsi: qla2xxx: Fix an integer overflow in sysfs code

The value of "size" comes from the user.  When we add "start + size" it
could lead to an integer overflow bug.

It means we vmalloc() a lot more memory than we had intended.  I believe
that on 64 bit systems vmalloc() can succeed even if we ask it to
allocate huge 4GB buffers.  So we would get memory corruption and likely
a crash when we call ha->isp_ops->write_optrom() and ->read_optrom().

Only root can trigger this bug.

Subject: scsi: qla2xxx: add missing includes for qla_isr

Since commit 7401bc18d1ee ("scsi: qla2xxx: Add FC-NVMe command
handling") we make use of 'struct nvmefc_fcp_req' in
qla24xx_nvme_iocb_entry() without including linux/nvme-fc-driver.h where
it is defined.

Add linux/nvme-fc-driver.h (and scsi/fc/fc_fs.h as nvme-fc-driver.h
needs the definition of 'struct fc_ba_rjt' from scsi/fc/fc_fs.h) to the
header files included by qla_isr.c.

 IRQs

This patch set IRQ affinity hint for FlexRM ring IRQ at time of
enabling ring (i.e. flexrm_startup()). The IRQ affinity hint will
allow FlexRM driver to distribute FlexRM ring IRQs across online
CPUs so that all FlexRM ring IRQs don't land in CPU0 by default.

Subject: mailbox: bcm-flexrm-mailbox: Fix mask used in CMPL_START_ADDR_VALUE()

The mask used in CMPL_START_ADDR_VALUE() should be 27bits instead of
26bits. This incorrect mask was causing completion writes to 40bits
physical address fail.

This patch fixes mask used in CMPL_START_ADDR_VALUE() macro.

Subject: mailbox: bcm-flexrm-mailbox: Use bitmap instead of IDA

Currently, we are using IDA library for managing IDs
on a FlexRM ring. The IDA library dynamically allocates
memory for underlying data structures which can cause
potential locking issue when allocating/free IDs from
flexrm_new_request() and flexrm_process_completions().

To tackle this, we replace use of IDA with bitmap for
each FlexRM ring and also protect the bitmap with FlexRM
ring lock.

Subject: mailbox: bcm-flexrm-mailbox: Use txdone_ack instead of txdone_poll

Currently, FlexRM driver uses txdone_poll method of Linux Mailbox
to model the send_data() callback. To achieve this, we have introduced
"last_pending_msg" pointer for each FlexRM ring which keeps track of
the message that did not fit in the FlexRM ring.

This patch updates FlexRM driver to use txdone_ack method instead of
txdone_poll method because txdone_poll is not efficient for FlexRM
and requires additional tracking in FlexRM driver.

Also, moving to txdone_ack method helps us remove "last_pending_msg"
pointer and last_tx_done() callback.

Subject: powerpc/powernv: Move GET_FIELD/SET_FIELD to vas.h

Move the GET_FIELD and SET_FIELD macros to vas.h as VAS and other
users of VAS, including NX-842 can use those macros.

There is a lot of related code between the VAS/NX kernel drivers
and skiboot. For consistency, switch the order of parameters in
SET_FIELD to match the order in skiboot.

Subject: powerpc/mm/cxl: Add barrier when setting mm cpumask

We need to add memory barrier so that the page table walk doesn't happen
before the cpumask is set and made visible to the other cpus. We need
to use a sync here instead of lwsync because lwsync is not sufficient for
store/load ordering.

We also need to add an if (mm) check so that we do the right thing when called
with a kernel context. For kernel context, we have mm = NULL. W.r.t kernel
address we can skip setting the mm cpumask.

Subject: cxl: Fix driver use count

cxl keeps a driver use count, which is used with the hash memory model
on p8 to know when to upgrade local TLBIs to global and to trigger
callbacks to manage the MMU for PSL8.

If a process opens a context and closes without attaching or fails the
attachment, the driver use count is never decremented. As a
consequence, TLB invalidations remain global, even if there are no
active cxl contexts.

We should increment the driver use count when the process is attaching
to the cxl adapter, and not on open. It's not needed before the
adapter starts using the context and the use count is decremented on
the detach path, so it makes more sense.

It affects only the user api. The kernel api is already doing The
Right Thing.

Subject: liquidio: fix crash in presence of zeroed-out base address regs

Fix crash in linux PF driver when BARs have been cleared/de-programmed;
fail early init (prior to mapping BARs) if the BAR0 or
BAR1 registers are zero.

This situation can arise when the PF is added to a VM (PCI pass-through),
then a PF FLR is issued (in the VM).  After this occurs, the BAR registers
will be zero. If we attempt to load the PF driver in the host
(after VM has been shutdown), the host can reset.

Subject: clk: imx: constify clk_div_table

clk_div_table are not supposed to change at runtime. All functions
working with clk_div_table provided by <linux/clk-provider.h> work
with const clk_div_table. So mark the non-const structs as const.

Subject: ARC: clk: introduce HSDK pll driver

HSDK board manages its clocks using various PLLs. These PLL have same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.

Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.

We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.

As of today we add support for PLLs that generate clock for the
HSDK arc cpus, system, ddr, AXI tunnel and hdmi.

By this patch we add support for several plls (arc cpus pll and others),
so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll
and regular probing for others plls.

Subject: clk: sunxi: fix uninitialized access

gcc-8 reports an uninitialized variable access in a code path
that we would see with incorrect DTB input:

drivers/clk/sunxi/clk-sun8i-bus-gates.c: In function 'sun8i_h3_bus_gates_init':
drivers/clk/sunxi/clk-sun8i-bus-gates.c:85:27: error: 'clk_parent' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This works around by skipping invalid input and printing a warning
instead if it ever happens. The problem was apparently part of the
initiali driver submission, but older compilers don't notice it.

Subject: pinctrl: mediatek: update PCIe mux data for MT7623

MT2701 shares the same driver with MT7623, but there is a slight difference
between their pin functions (e.g., PCIe), so we update the different parts
in pinmux table.

Doing so, SoC could choose the correct mux setting via their own pinfun.h.

Subject: pinctrl: Add sleep related state to indicate sleep related configs

In some scenarios, we should set some pins as input/output/pullup/pulldown
when the specified system goes into deep sleep mode, then when the system
goes into deep sleep mode, these pins will be set automatically by hardware.

That means some pins are not controlled by any specific driver in the OS, but
need to be controlled when entering sleep mode. Thus we introduce one sleep
state config into pinconf-generic for users to configure.

Subject: mmc: meson-gx: fix __ffsdi2 undefined on arm32

Using __bf_shf does not compile on arm 32 architecture.
This has gone unnoticed till now cause the driver is only used on arm64.

In addition, __bf_shf was already used in the driver without any issue.
It was used on a constant value, so the call was probably optimized
away.

Replace __bf_shf by __ffs fixes the problem

Subject: pinctrl: aspeed: Rework strap register write logic for the AST2500

Yong Li found that writes to the AST2500 strapping register were not
properly supported by the Aspeed pinctrl core and provided a patch to
rectify the problem. Several revisions of the patch were posted and
ultimately v4 should have been applied, however some unfortunate
liberal application of tags on my part lead to confusion between v3[1]
and v4[2].

Generate the diff between v3 and v4 to apply as a fixup patch.

Subject: ath10k: fix napi_poll budget overflow

In napi_poll, the budget number is used to control the amount of packets
we should handle per poll to balance the resource in the system.

In the list of the amsdu packets reception, we check if there is budget
count left and handle the complete list of the packets, that it will have
chances the very last list will over the budget leftover.

So adding one more parameter - budget_left, this would help while
traversing the list to avoid handling more than the budget given.

Subject: ath10k: sdio: remove unused struct member

irq_wq in struct ath10k_sdio is a remnant from an earlier
version of the sdio patchset.

Its use was removed as a result of Kalle's review, but somehow
the struct member survived.

It is not used and can therefore safely be removed.

Subject: ath10k: activate user space firmware loading again

In commit 9f5bcfe93315 ("ath10k: silence firmware file probing
warnings") the firmware loading was changed from request_firmware() to
request_firmware_direct() to silence some warnings in case it fails.
request_firmware_direct() directly searches in the file system only and
does not send a hotplug event to user space in case it could not find
the firmware directly.
In LEDE we use a user space script to extract the calibration data from
the flash memory which gets triggered by the hotplug event. This way the
firmware gets extracted from some vendor specific partition when the
driver requests this firmware. This mechanism does not work any more
after this change.

Subject: wil6210: ratelimit errors in TX/RX interrupts

Sometimes there is a firmware crash but the hardware
is not fully stopped and continue to send TX/RX interrupts.
This can cause an overload of messages which can bring the
host down. Add ratelimit to these error messages to fix this.

Subject: wil6210: clear PAL_UNIT_ICR part of device reset

When FW starts running it can get D0 to D3 interrupt that is a leftover
from previous system suspend while FW was not running.
As this interrupt is not relevant anymore, clear it part of device reset
procedure.

Subject: wil6210: ensure P2P device is stopped before removing interface

User space can remove the P2P management interface while it is active

a crash. Ensure the P2P device is fully stopped before removing.

Subject: IB/cm: Fix sleeping in atomic when RoCE is used

A couple of places in the CM do

    spin_lock_irq(&cm_id_priv->lock);
    ...
    if (cm_alloc_response_msg(work->port, work->mad_recv_wc, &msg))

However when the underlying transport is RoCE, this leads to a sleeping function
being called with the lock held - the callchain is

    cm_alloc_response_msg() ->
      ib_create_ah_from_wc() ->
        ib_init_ah_from_wc() ->
          rdma_addr_find_l2_eth_by_grh() ->
            rdma_resolve_ip()

and rdma_resolve_ip() starts out by doing

    req = kzalloc(sizeof *req, GFP_KERNEL);

not to mention rdma_addr_find_l2_eth_by_grh() doing

    wait_for_completion(&ctx.comp);

to wait for the task that rdma_resolve_ip() queues up.

Fix this by moving the AH creation out of the lock.

Subject: IB/core: Add might_sleep() annotation to ib_init_ah_from_wc()

For RoCE, ib_init_ah_from_wc() can follow the path

    ib_init_ah_from_wc() ->
      rdma_addr_find_l2_eth_by_grh() ->
        rdma_resolve_ip()

and rdma_resolve_ip() will sleep in kzalloc() and wait_for_completion().

However, developers will not see any warnings if they use ib_init_ah_from_wc()
in an atomic context and test only on IB, because the function doesn't
sleep in that case.

Add a might_sleep() so that lockdep will catch bugs no matter what hardware is
used to test.

Subject: IB/core: Add new ioctl interface

In this ioctl interface, processing the command starts from
properties of the command and fetching the appropriate user objects
before calling the handler.

Parsing and validation is done according to a specifier declared by
the driver's code. In the driver, all supported objects are declared.
These objects are separated to different object namepsaces. Dividing
objects to namespaces is done at initialization by using the higher
bits of the object ids. This initialization can mix objects declared
in different places to one parsing tree using in this ioctl interface.

For each object we list all supported methods. Similarly to objects,
methods are separated to method namespaces too. Namespacing is done
similarly to the objects case. This could be used in order to add
methods to an existing object.

Each method has a specific handler, which could be either a default
handler or a driver specific handler.
Along with the handler, a bunch of attributes are specified as well.
Similarly to objects and method, attributes are namespaced and hashed
by their ids at initialization too. All supported attributes are
subject to automatic fetching and validation. These attributes include
the command, response and the method's related objects' ids.

When these entities (objects, methods and attributes) are used, the
high bits of the entities ids are used in order to calculate the hash
bucket index. Then, these high bits are masked out in order to have a
zero based index. Since we use these high bits for both bucketing and
namespacing, we get a compact representation and O(1) array access.
This is mandatory for efficient dispatching.

Each attribute has a type (PTR_IN, PTR_OUT, IDR and FD) and a length.
Attributes could be validated through some attributes, like:
(*) Minimum size / Exact size
(*) Fops for FD
(*) Object type for IDR

If an IDR/fd attribute is specified, the kernel also states the object
type and the required access (NEW, WRITE, READ or DESTROY).
All uobject/fd management is done automatically by the infrastructure,
meaning - the infrastructure will fail concurrent commands that at
least one of them requires concurrent access (WRITE/DESTROY),
synchronize actions with device removals (dissociate context events)
and take care of reference counting (increase/decrease) for concurrent
actions invocation. The reference counts on the actual kernel objects
shall be handled by the handlers.

[d] = Hash ids to groups using the high order bits

The right types table is also chosen by using the high bits from
the ids. Currently we have either default or driver specific groups.

Once validation and object fetching (or creation) completed, we call
the handler:
int (*handler)(struct ib_device *ib_dev, struct ib_uverbs_file *ufile,
               struct uverbs_attr_bundle *ctx);

ctx bundles attributes of different namespaces. Each element there
is an array of attributes which corresponds to one namespaces of
attributes. For example, in the usually used case:

Subject: IB/core: Declare an object instead of declaring only type attributes

Switch all uverbs_type_attrs_xxxx with DECLARE_UVERBS_OBJECT
macros. This will be later used in order to embed the object
specific methods in the objects as well.

Subject: IB/core: Add DEVICE object and root tree structure

This adds the DEVICE object. This object supports creating the context
that all objects are created from. Moreover, it supports executing
methods which are related to the device itself, such as QUERY_DEVICE.
This is a singleton object (per file instance).

All standard objects are put in the root structure. This root will later
on be used in drivers as the source for their whole parsing tree.
Later on, when new features are added, these drivers could mix this root
with other customized objects.

Subject: IB/core: Add uverbs merge trees functionality

Different drivers support different features and even subset of the
common uverbs implementation. Currently, this is handled as bitmask
in every driver that represents which kind of methods it supports, but
doesn't go down to attributes granularity. Moreover, drivers might
want to add their specific types, methods and attributes to let
their user-space counter-parts be exposed to some more efficient
abstractions. It means that existence of different features is
validated syntactically via the parsing infrastructure rather than
using a complex in-handler logic.

In order to do that, we allow defining features and abstractions
as parsing trees. These per-feature parsing tree could be merged
to an efficient (perfect-hash based) parsing tree, which is later
used by the parsing infrastructure.

To sum it up, this makes a parse tree unique for a device and
represents only the features this particular device supports.
This is done by having a root specification tree per feature.
Before a device registers itself as an IB device, it merges
all these trees into one parsing tree. This parsing tree
is used to parse all user-space commands.

A future user-space application could read this parse tree. This
tree represents which objects, methods and attributes are
supported by this device.

This is based on the idea of

Subject: IB/core: Explicitly destroy an object while keeping uobject

When some objects are destroyed, we need to extract their status at
destruction. After object's destruction, this status
(e.g. events_reported) relies in the uobject. In order to have the
latest and correct status, the underlying object should be destroyed,
but we should keep the uobject alive and read this information off the
uobject. We introduce a rdma_explicit_destroy function. This function
destroys the class type object (for example, the IDR class type which
destroys the underlying object as well) and then convert the uobject
to be of a null class type. This uobject will then be destroyed as any
other uobject once uverbs_finalize_object[s] is called.

Subject: IB/core: Add legacy driver's user-data

In this phase, we don't want to change all the drivers to use
flexible driver's specific attributes. Therefore, we add two default
attributes: UHW_IN and UHW_OUT. These attributes are optional in some
methods and they encode the driver specific command data. We add
a function that extract this data and creates the legacy udata over
it.

Driver's data should start from UVERBS_UDATA_DRIVER_DATA_FLAG. This
turns on the first bit of the namespace, indicating this attribute
belongs to the driver's namespace.

Subject: IB/core: Add completion queue (cq) object actions

Adding CQ ioctl actions:
1. create_cq
2. destroy_cq

This requires adding the following:
1. A specification describing the method
	a. Handler
	b. Attributes specification
		Each attribute is one of the following:
		a. PTR_IN - input data
			    Note: This could be encoded inlined for
				  data < 64bit
		b. PTR_OUT - response data
		c. IDR - idr based object
		d. FD - fd based object
                Blobs attributes (clauses a and b) contain their type,
	        while objects specifications (clauses c and d)
                contains the expected object type (for example, the
                given id should be UVERBS_TYPE_PD) and the required
                access (READ, WRITE, NEW or DESTROY). If a NEW is
                required, the new object's id will be assigned to this
                attribute. All attributes could get UA_FLAGS
                attribute. Currently we support stating that an
		attribute is mandatory or that the specification size
                corresponds to a lower bound (and that this attribute
		could be extended).
		We currently add both default attributes and the two
		generic UHW_IN and UHW_OUT driver specific attributes.
2. Handler
   A handler gets a uverbs_attr_bundle. The handler developer uses
   uverbs_attr_get to fetch an attribute of a given id.
   Each of these attribute groups correspond to the specification
   group defined in the action (clauses 1.b and 1.c respectively).
   The indices of these arrays corresponds to the attribute ids
   declared in the specifications (clause 2).

   The handler is quite simple. It assumes the infrastructure fetched
   all objects and locked, created or destroyed them as required by
   the specification. Pointer (or blob) attributes were validated to
   match their required sizes. After the handler finished, the
   infrastructure commits or rollbacks the objects.

Subject: IB/core: Assign root to all drivers

In order to use the parsing tree, we need to assign the root
to all drivers. Currently, we just assign the default parsing
tree via ib_uverbs_add_one. The driver could override this by
assigning a parsing tree prior to registering the device.

Subject: xen/pvcalls: connect to a frontend

Introduce a per-frontend data structure named pvcalls_fedata. It
contains pointers to the command ring, its event channel, a list of
active sockets and a tree of passive sockets (passing sockets need to be
looked up from the id on listen, accept and poll commands, while active
sockets only on release).

It also has an unbound workqueue to schedule the work of parsing and
executing commands on the command ring. socket_lock protects the two
lists. In pvcalls_back_global, keep a list of connected frontends.

Subject: xen/pvcalls: handle commands from the frontend

When the other end notifies us that there are commands to be read
(pvcalls_back_event), wake up the backend thread to parse the command.

The command ring works like most other Xen rings, so use the usual
ring macros to read and write to it. The functions implementing the
commands are empty stubs for now.

Subject: xen/pvcalls: implement connect command

Allocate a socket. Keep track of socket <-> ring mappings with a new data
structure, called sock_mapping. Implement the connect command by calling
inet_stream_connect, and mapping the new indexes page and data ring.
Allocate a workqueue and a work_struct, called ioworker, to perform
reads and writes to the socket.

When an active socket is closed (sk_state_change), set in_error to
-ENOTCONN and notify the other end, as specified by the protocol.

sk_data_ready and pvcalls_back_ioworker will be implemented later.

Subject: xen/pvcalls: implement bind command

Allocate a socket. Track the allocated passive sockets with a new data
structure named sockpass_mapping. It contains an unbound workqueue to
schedule delayed work for the accept and poll commands. It also has a
reqcopy field to be used to store a copy of a request for delayed work.
Reads/writes to it are protected by a lock (the "copy_lock" spinlock).
Initialize the workqueue in pvcalls_back_bind.

Implement the bind command with inet_bind.

The pass_sk_data_ready event handler will be added later.

Subject: xen/pvcalls: implement accept command

Implement the accept command by calling inet_accept. To avoid blocking
in the kernel, call inet_accept(O_NONBLOCK) from a workqueue, which get
scheduled on sk_data_ready (for a passive socket, it means that there
are connections to accept).

Use the reqcopy field to store the request. Accept the new socket from
the delayed work function, create a new sock_mapping for it, map
the indexes page and data ring, and reply to the other end. Allocate an
ioworker for the socket.

Only support one outstanding blocking accept request for every socket at
any time.

Add a field to sock_mapping to remember the passive socket from which an
active socket was created.

Subject: xen/pvcalls: implement poll command

Implement poll on passive sockets by requesting a delayed response with
mappass->reqcopy, and reply back when there is data on the passive
socket.

Poll on active socket is unimplemented as by the spec, as the frontend
should just wait for events and check the indexes on the indexes page.

Only support one outstanding poll (or accept) request for every passive
socket at any given time.

Subject: xen/pvcalls: implement release command

Release both active and passive sockets. For active sockets, make sure
to avoid possible conflicts with the ioworker reading/writing to those
sockets concurrently. Set map->release to let the ioworker know
atomically that the socket will be released soon, then wait until the
ioworker finishes (flush_work).

Unmap indexes pages and data rings.

Implement backend_disconnect. Call pvcalls_back_release_active on active
sockets and pvcalls_back_release_passive on passive sockets.

Implement module_exit by calling backend_disconnect on frontend
connections.

Subject: xen/pvcalls: implement the ioworker functions

We have one ioworker per socket. Each ioworker goes through the list of
outstanding read/write requests. Once all requests have been dealt with,
it returns.

We use one atomic counter per socket for "read" operations and one
for "write" operations to keep track of the reads/writes to do.

We also use one atomic counter ("io") per ioworker to keep track of how
many outstanding requests we have in total assigned to the ioworker. The
ioworker finishes when there are none.

Subject: xen/pvcalls: use WARN_ON(1) instead of __WARN()

__WARN() is an internal helper that is only available on
some architectures, but causes a build error e.g. on ARM64
in some configurations:

drivers/xen/pvcalls-back.c: In function 'set_backend_state':
drivers/xen/pvcalls-back.c:1097:5: error: implicit declaration of function '__WARN' [-Werror=implicit-function-declaration]

Unfortunately, there is no equivalent of BUG() that takes no
arguments, but WARN_ON(1) is commonly used in other drivers
and works on all configurations.

This is because get_cpu() in xen_evtchn_fifo_init() will disable
preemption, but __get_free_page() might sleep (GFP_ATOMIC is not set).

xen_evtchn_fifo_init() will always be called before SMP is initialized,
so {get,put}_cpu() could be replaced by a simple smp_processor_id().

This also avoid to modify evtchn_fifo_alloc_control_block that will be
called in other context.

Subject: xen: Don't try to call xen_alloc_p2m_entry() on autotranslating
 guests

Commit aba831a69632 ("xen: remove tests for pvh mode in pure pv paths")
removed XENFEAT_auto_translated_physmap test in xen_alloc_p2m_entry()
since it is assumed that the routine is never called by non-PV guests.

However, alloc_xenballooned_pages() may make this call on a PVH guest.
Prevent this from happening by adding XENFEAT_auto_translated_physmap
check there.

Subject: irqchip/gic-v3-its: Add VLPI map/unmap operations

In order to let a VLPI being injected into a guest, the VLPI must
be mapped using the VMAPTI command. When moved to a different vcpu,
it must be moved with the VMOVI command.

These commands are issued via the irq_set_vcpu_affinity method,
making sure we unmap the corresponding host LPI first.

The reverse is also done when the VLPI is unmapped from the guest.

Subject: irqchip/gic-v3-its: Add VLPI configuration handling

When a VLPI is reconfigured (enabled, disabled, change in priority),
the full configuration byte must be written, and the caches invalidated.

Also, when using the irq_mask/irq_unmask methods, it is necessary
to disable the doorbell for that particular interrupt (by mapping it
to 1023) on top of clearing the Enable bit.

- allocating each VPE a unique VPEID
- allocating a doorbell interrupt for each VPE
- allocating the pending tables for each VPE
- allocating the property table for the VM

This of course has to be reversed when the VM is brought down.

All of this is wired into the irq domain alloc/free methods.

Subject: irqchip/gic-v3-its: Add VPE irq domain [de]activation

On activation, a VPE is mapped using the VMAPP command, followed
by a VINVALL for a good measure. On deactivation, the VPE is
simply unmapped.

Subject: irqchip/gic-v3-its: Add VPE scheduling

When a VPE is scheduled to run, the corresponding redistributor must
be told so, by setting VPROPBASER to the VM's property table, and
VPENDBASER to the vcpu's pending table.

When scheduled out, we preserve the IDAI and PendingLast bits. The
latter is specially important, as it tells the hypervisor that
there are pending interrupts for this vcpu.

Subject: irqchip/gic-v3-its: Add VPE invalidation hook

When a guest issues a INVALL command targetting a collection, it must
be translated into a VINVALL for the VPE that has this collection.

This patch implements a hook that offers this functionallity to the
hypervisor.

Subject: irqchip/gic-v3-its: Add VPE affinity changes

When we're about to run a vcpu, it is crucial that the redistributor
associated with the physical CPU is being told about the new residency.

This is abstracted by hijacking the irq_set_affinity method for the
doorbell interrupt associated with the VPE. It is expected that the
hypervisor will call this method before scheduling the VPE.

When masking/unmasking a doorbell interrupt, it is necessary
to issue an invalidation to the corresponding redistributor.
We use the DirectLPI feature by writting directly to the corresponding

Subject: irqchip/gic-v3-its: Make LPI allocation optional on device creation

The normal course of action when allocating the ITS' view of a
device is to allocate the corresponding LPIs. But we're about
to introduce devices that borrow their interrupts from
some other entities.

So let's make the allocation optional.

Subject: irqchip/gic-v3-its: Add device proxy for VPE management if !DirectLpi

When we don't have the DirectLPI feature, we must work around the
architecture shortcomings to be able to perform the required
maintenance (interrupt masking, clearing and injection).

For this, we create a fake device whose sole purpose is to
provide a way to issue commands as if we were dealing with LPIs
coming from that device (while they actually originate from
the ITS). This fake device doesn't have LPIs allocated to it,
but instead uses the VPE LPIs.

Of course, this could be a real bottleneck, and a naive
implementation would require 6 commands to issue an invalidation.

Instead, let's allocate at least one event per physical CPU
(rounded up to the next power of 2), and opportunistically
map the VPE doorbell to an event. This doorbell will be mapped
until we roll over and need to reallocate this slot.

This ensures that most of the time, we only need 2 commands
to issue an INV, INT or CLEAR, making the performance a lot
better, given that we always issue a CLEAR on entry, and
an INV on each side of a trapped WFI.

Subject: irqchip/gic-v3-its: Move pending doorbell after VMOVP

After moving a VPE from a redistributor to another, we're still left
with a potential pending doorbell interrupt on the old redistributor.
That interrupt should be moved to the new one to be either cleared
or take, depending on what the hypervisor wishes to do.

So let's move it right after having execited VMOVP. This doesn't
add much cost in the !DirectLPI case (we trade a DISCARD for a MOVI),
and the cost of the DIRECTLPI case should be minimal (two extra MMIO
accesses).

Subject: irqchip/gic-v3-its: Allow doorbell interrupts to be injected/cleared

While the doorbell interrupts are usually driven by the HW itself,
having a way to trigger them independently has proved to be a
really useful debug feature. As it is actually very little code,
let's add it to the VPE irqchip operations.

Subject: irqchip/gic-v3-its: Set implementation defined bit to enable VLPIs

A long time ago, GITS_CTLR[1] used to be called GITC_CTLR.EnableVLPI.
It has been subsequently deprecated and is now an "Implementation
Defined" bit that may ot may not be set for GICv4. Brilliant.

And the current crop of the FastModel requires that bit for VLPIs
to be enabled. Oh well... Let's set it and find out what breaks.

+/*
+ * WARNING: The blurb below assumes that you understand the
+ * intricacies of GICv3, GICv4, and how a guest's view of a GICv3 gets
+ * translated into GICv4 commands. So it effectively targets at most
+ * two individuals. You know who you are.
+ *
+ * The core GICv4 code is designed to *avoid* exposing too much of the
+ * core GIC code (that would in turn leak into the hypervisor code),
+ * and instead provide a hypervisor agnostic interface to the HW (of
+ * course, the astute reader will quickly realize that hypervisor
+ * agnostic actually means KVM-specific - what were you thinking?).
+ *
+ * In order to achieve a modicum of isolation, we try to hide most of
+ * the GICv4 "stuff" behind normal irqchip operations:
+ *
+ * - Any guest-visible VLPI is backed by a Linux interrupt (and a
+ *   physical LPI which gets unmapped when the guest maps the
+ *   VLPI). This allows the same DevID/EventID pair to be either
+ *   mapped to the LPI (host) or the VLPI (guest). Note that this is
+ *   exclusive, and you cannot have both.
+ *
+ * - Enabling/disabling a VLPI is done by issuing mask/unmask calls.
+ *
+ * - Guest INT/CLEAR commands are implemented through
+ *   irq_set_irqchip_state().
+ *
+ * - The *bizarre* stuff (mapping/unmapping an interrupt to a VLPI, or
+ *   issuing an INV after changing a priority) gets shoved into the
+ *   irq_set_vcpu_affinity() method. While this is quite horrible
+ *   (let's face it, this is the irqchip version of an ioctl), it
+ *   confines the crap to a single location. And map/unmap really is
+ *   about setting the affinity of a VLPI to a vcpu, so only INV is
+ *   majorly out of place. So there.
+ *
+ * A number of commands are simply not provided by this interface, as
+ * they do not make direct sense. For example, MAPD is purely local to
+ * the virtual ITS (because it references a virtual device, and the
+ * physical ITS is still very much in charge of the physical
+ * device). Same goes for things like MAPC (the physical ITS deals
+ * with the actual vPE affinity, and not the braindead concept of
+ * collection). SYNC is not provided either, as each and every command
+ * is followed by a VSYNC. This could be relaxed in the future, should
+ * this be seen as a bottleneck (yes, this means *never*).
+ *
+ * But handling VLPIs is only one side of the job of the GICv4
+ * code. The other (darker) side is to take care of the doorbell
+ * interrupts which are delivered when a VLPI targeting a non-running
+ * vcpu is being made pending.
+ *
+ * The choice made here is that each vcpu (VPE in old northern GICv4
+ * dialect) gets a single doorbell LPI, no matter how many interrupts
+ * are targeting it. This has a nice property, which is that the
+ * interrupt becomes a handle for the VPE, and that the hypervisor
+ * code can manipulate it through the normal interrupt API:
+ *
+ * - VMs (or rather the VM abstraction that matters to the GIC)
+ *   contain an irq domain where each interrupt maps to a VPE. In
+ *   turn, this domain sits on top of the normal LPI allocator, and a
+ *   specially crafted irq_chip implementation.
+ *
+ * - mask/unmask do what is expected on the doorbell interrupt.
+ *
+ * - irq_set_affinity is used to move a VPE from one redistributor to
+ *   another.
+ *
+ * - irq_set_vcpu_affinity once again gets hijacked for the purpose of
+ *   creating a new sub-API, namely scheduling/descheduling a VPE
+ *   (which involves programming GICR_V{PROP,PEND}BASER) and
+ *   performing INVALL operations.

LS1046a includes 4 MSIRs, each MSIR is assigned a dedicate GIC
SPI interrupt and provides 32 MSI interrupts. Compared to previous
MSI, LS1046a's IBS(interrupt bit select) shift is changed to 2 and
total MSI interrupt number is changed to 128.

The patch adds structure 'ls_scfg_msir' to describe MSIR setting and
'ibs_shift' to store the different value between the SoCs.

Subject: irqchip/ls-scfg-msi: Add LS1043a v1.1 MSI support

A MSI controller of LS1043a v1.0 only includes one MSIR and
is assigned one GIC interrupt. In order to support affinity,
LS1043a v1.1 MSI is assigned 4 MSIRs and 4 GIC interrupts.
But the MSIR has the different offset and only supports 8 MSIs.
The bits between variable bit_start and bit_end in structure
ls_scfg_msir are used to show 8 MSI interrupts. msir_irqs and
msir_base are added to describe the difference of MSI between
LS1043a v1.1 and other SoCs.

Subject: irqchip/ls-scfg-msi: Add MSI affinity support

For LS1046a and LS1043a v1.1, the MSI controller has 4 MSIRs and 4 GIC
SPI interrupts which can be associated with different Core.
So we can support affinity to improve the performance.
The MSI message data is a byte for Layerscape MSI.
  7    6   5  4  3  2   1   0
| - |       IBS       |  SRS |
SRS bit0-1 is to select a MSIR which is associated with a CPU.
IBS bit2-6 of ls1046, bit2-4 of ls1043a v1.1 is to select bit of the
MSIR. With affinity, only bits of MSIR0(srs=0 cpu0) are available.
All other bits of the MSIR1-3(cpu1-3) are reserved. The MSI hwirq
always equals bit index of the MSIR0. When changing affinity, MSI
message data will be appended corresponding SRS then MSI will be
moved to the corresponding core.
But in affinity mode, there is only 8 MSI interrupts for a controller
of LS1043a v1.1. It cannot meet the requirement of the some PCIe
devices such as 4 ports Ethernet card. In contrast, without affinity,
all MSIRs can be used for core 0, the MSI interrupts can up to 32.
So the parameter is added to control affinity mode.
"lsmsi=no-affinity" will disable affinity and increase MSI
interrupt number.

Subject: usbip: auto retry for concurrent attach

This patch adds recovery from false busy state on concurrent attach
operation.

The procedure of attach operation is as below.
1) Find an unused port in /sys/devices/platform/vhci_hcd/status.
(userspace)
2) Request attach found port to driver through
/sys/devices/platform/vhci_hcd/attach. (userspace)
3) Lock table, reserve requested port and unlock table. (vhci driver)

Attaching more than one remote devices concurrently, same unused port
number will be found in step-1. Then one request will succeed and
others will fail even though there are some unused ports.

With this patch, driver returns EBUSY when requested port has already
been used. In this case, attach command retries from step-1: finding
another unused port. If there's no unused port, the attach operation
will fail in step-1. Otherwise it retries automatically using another
unused port.

vhci-hcd's interface (only errno) is changed as following.

Current	errno	New errno	Condition
EINVAL		same as left	specified port number is in invalid
				range
EAGAIN		same as left	platform_get_drvdata() failed
EINVAL		same as left	specified socket fd is not valid
EINVAL		EBUSY		specified port status is not free

The errno EBUSY was not used in userspace
src/usbip_attach.c:import_device(). It is needed to distinguish the
condition to be able to retry from other unrecoverable errors.

It is possible to avoid this failure by introducing userspace exclusive
control. But it's exaggerated for this special condition. The locking
itself has done in driver.
As an alternate solution, userspace doesn't specify port number, driver
searches unused port and it returns port number to the userspace. With
this solution, the interface is much different than this patch.

Subject: staging: unisys: visorbus: Clean up vmcall address function.

The function vmcall address needed to be cleaned up. The structure
vmcall_controlvm_addr was not needed so it was removed and was replaced
with vmcall_io_controlvm_addr_params since it needs to be allocated on the
heap for DMA access.

With the structure removed and the fields as local variables, it helped
clean up the formatting of the function.

The macro to convert to the driver object was giving a checkpatch warning
when it ateempted to check for a null driver. It would return NULL if it
found it, but only one location was checking to see if it was NULL.

Remove the check in the MACRO and do it prior to calling the macro if
required.

Subject: staging: unisys: Change data to point to
 visor_controlvm_parameters_header.

The data field was being defined as a character array and then casted into
a visor_controlvm_parameters_header structure. This patch converts it to
just point to the visor_controlvm_parameters_header structure. The data
following the header is still behind the header_info.

Subject: staging: typec: tcpm: Add get_current_limit tcpc_dev callback

A Rp signalling the default current limit indicates that we're possibly
connected to an USB2 power-source. In some cases the type-c port-controller
may provide the capability to detect the current-limit in this case,
through e.g. BC1.2 detection.

This commit adds an optional get_current_limit tcpc_dev callback which
allows the port-controller to provide current-limit detection for when
the CC pin is pulled up with Rp.

Anything higher then 5V may damage hardware not capable of it, so
the only sane default here is 5V. If a board is able to handle a
higher voltage that should come from board specific data such as
device-tree and not be hard coded into the fusb302 code.

Subject: staging: typec: fusb302: Get max snk mv/ma/mw from device-properties

This is board specific info so it should come from board config, such
as devicetree.

I've chosen to prefix these with "fcs," treating them as fusb302 driver
specific for now. We may want to revisit this and replace these with
properties which are part of a (to be written) generic type-c controller
devicetree binding.

Since this commit adds new dt-properties it also adds devicetree-bindings
documentation (which so far was absent for the fusb302 driver).

Subject: staging: typec: fusb302: Add support for USB2 charger detection
 through extcon

The fusb302 port-controller relies on an external device doing USB2
charger-type detection.

The Intel Whiskey Cove PMIC with which the fusb302 is combined on some
X86/ACPI platforms already has a charger-type detection driver which
uses extcon to communicate the detected charger-type.

Rather then inventing a new API for USB2 charger-type detection
specifically for use with the tcpm code, this commit simply re-uses the
existing extcon API and uses that do USB2 charger detection.

Note that the "fcs,extcon-name" property name is only for kernel internal
use by X86/ACPI platform code and as such is NOT documented in
the fusb302 devicetree bindings.

Subject: staging: typec: fusb302: Export current-limit through a power_supply
 class dev

The fusb302 Type-C port-controller cannot control the current-limit
directly, so we need to exported the limit so that another driver
(e.g. the charger driver) can pick the limit up and configure the
system accordingly.

The power-supply subsys already provides infrastructure for this,
power-supply devices have the notion of being supplied by another
power-supply and have properties through which we can export the
current-limit.

Register a power_supply and export the current-limit through the
power_supply's current-max property.

Subject: staging: vboxvideo: Use CONFIG_DRM_KMS_FB_HELPER to check for fbdefio
 availability

Checking for CONFIG_FB_DEFERRED_IO is not the right thing to do since
the fbdev code may be built as a module while vboxvideo is builtin.

This can only happen when DRM_KMS_FB_HELPER is not set:
a) DRM_VBOXVIDEO selects DRM_KMS_HELPER
b) DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER
c) DRM_KMS_FB_HELPER selects FB_DEFERRED_IO

So when DRM_KMS_FB_HELPER is set and vboxvideo is builtin then
FB_DEFERRED_IO must be builtin too.

This commit moves the #ifdefs around fbdefio code over to
CONFIG_DRM_KMS_FB_HELPER, as other drm drivers already do, fixing:

drivers/staging/vboxvideo/vbox_fb.o: In function `vbox_fbdev_fini':
vbox_fb.c:(.text+0x36): undefined reference to `fb_deferred_io_cleanup'

Now that the extraneous debugging code is removed, routine deinit_priv()
clearly contains code that serves no useful purpose.

A null test before a call to kfree() and a spurious cast are also removed.

Subject: earlycon: initialise baud field of earlycon device structure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For now baud field of earlycon structure device is't initialised at all
in of_setup_earlycon (in oppositе to register_earlycon).

So when I use stdout-path to point earlycon device
(like stdout-path = &serial or stdout-path = "serial:115200n8")
baud field of earlycon device structure remains uninitialised and
earlycon initialization is not performed correctly as
of_setup_earlycon is used.
When pass all arguments via bootargs
(like bootargs = "earlycon=uart8250,mmio32,0xf0005000,115200n8")
initialization is performed correctly as register_earlycon is used.

So initialise baud field of earlycon device structure by value of
"current-speed" property from device tree or from options
(if they exist) when we use of_setup_earlycon

We should return the corresponding error code instead.

Remove the useless initialisation of 'ret' which was hiding the issue.

Subject: driver core: bus: Fix a potential double free

The .release function of driver_ktype is 'driver_release()'.
This function frees the container_of this kobject.

So, this memory must not be freed explicitly in the error handling path of
'bus_add_driver()'. Otherwise a double free will occur.

Subject: tty: goldfish: Refactor constants to better reflect their nature

Classify constants GOLDFISH_TTY_xxx into two groups: command ids and
register offsets. Apply different naming for register offsets (add
'REG_' after 'GOLDFISH_TTY_' in constant names). Change implementation
to use preprocessor's '#define' statements instead of 'enum'
declaration (as this is more common way of implementation in such
cases).

This makes the driver code easier to follow and hopefully prevents
future bugs.

Subject: tty: goldfish: Use streaming DMA for r/w operations on Ranchu
 platforms

Implement tty r/w operations using streaming DMA.

Goldfish tty for Ranchu platforms has been modified to use
streaming DMA mappings for read/write operations. This change
eliminates the need for snooping through the TLB in QEMU using
cpu_get_phys_page_debug() which does not guarantee that it will
return the valid va -> pa mapping.

The streaming DMA mapping is implemented using dma_map_single() per
transfer, while dma_unmap_single() is used for unmapping right after
the DMA transfer.

Using DMA API is the proper way for handling r/w transfers and
makes this driver more portable, thus effectively eliminating
the need for virt_to_page() and page_to_phys() conversions.

This change does not affect the old style Goldfish tty behaviour
which is still used by the Goldfish emulator. Version register has
been added and probed to see which platform is running this driver.
Reading from the new register GOLDFISH_TTY_REG_VERSION using the
Goldfish emulator will return 0 and driver will work with virtual
addresses. Whereas if run on Ranchu it returns 1, and thus DMA is
used.

(Goldfish and Ranchu are code names for the first and the second
generation of virtual boards used by Android emulator.)

Subject: tty: goldfish: Implement support for kernel 'earlycon' parameter

Add early console functionality to the Goldfish tty driver.

When 'earlycon' kernel command line parameter is used with no options,
the early console is determined by the 'stdout-path' property in device
tree's 'chosen' node. This is illustrated in the following device tree
source example:

Device tree example:

    chosen {
        stdout-path = "/goldfish_tty@1f004000";
    };

    goldfish_tty@1f004000 {
        interrupts = <0xc>;
        reg = <0x1f004000 0x0 0x1000>;
        compatible = "google,goldfish-tty";
    };

Subject: ath10k: add the PCI PM core suspend/resume ops

The actual PCI suspend/resume in ath10k has been handled in wow.c,
but in the case of the device doesn't support remote wakeup,
the .hif_suspend() and .hif_resume() will never be handled.

  ath10k_wow_op_suspend()
  {
	if (WARN_ON(!test_bit(ATH10K_FW_FEATURE_WOWLAN_SUPPORT,
		    ar->running_fw->fw_file.fw_features))) {
		ret = 1;
		goto exit;
	}

	....

	ret = ath10k_hif_suspend(ar);
  }

So register the PCI PM core to support the suspend/resume if the device
doesn't support remote wakeup.

Subject: ath10k: configure and enable the wakeup capability

ACPI will rely on device driver to tell it if the device could support
wakeup function when system in D3 state.

This has caused some platform can't support remote wakeup correctly,
because the ACPI wakeup GPE is not enabled, hence registers the .set_wakeup
callback to handle it if device supports wakeup.

Tested with QCA6174 hw3.0, firmware ('WLAN.RM.4.4.1-00008-QCARMSWP-1')

Subject: i2c: designware: Round down ACPI provided clk to nearest supported
 clk

The Lenovo Miix2 8 DSDT contains an i2c clk / bus speed of 1700000 Hz
for one if its devices, which is not supported.

This is the second DSDT to show up with an unsupported clk in a short
time, remove the hardcoded fix for DSDTs with a 1 MiHz clock and simply
always round down the clk to the nearest supported value.

Subject: Input: xpad - fix PowerA init quirk for some gamepad models

The PowerA gamepad initialization quirk worked with the PowerA
wired gamepad I had around (0x24c6:0x543a), but a user reported [0]
that it didn't work for him, even though our gamepads shared the
same vendor and product IDs.

When I initially implemented the PowerA quirk, I wanted to avoid
actually triggering the rumble action during init. My tests showed
that my gamepad would work correctly even if it received a rumble
of 0 intensity, so that's what I went with.

Unfortunately, this apparently isn't true for all models (perhaps
a firmware difference?). This non-working gamepad seems to require
the real magic rumble packet that the Microsoft driver sends, which
actually vibrates the gamepad. To counteract this effect, I still
send the old zero-rumble PowerA quirk packet which cancels the
rumble effect before the motors can spin up enough to vibrate.

Subject: loop: set physical block size to PAGE_SIZE

The physical block size is "the lowest possible sector size that the
hardware can operate on without reverting to read-modify-write
operations" (from the comment on blk_queue_physical_block_size()). Since
loop does buffered I/O on the backing file by default, the RMW unit is a
page. This isn't the case for direct I/O mode, but let's keep it simple.

Subject: loop: add ioctl for changing logical block size

This is a different approach from the first attempt in f2c6df7dbf9a
("loop: support 4k physical blocksize"). Rather than extending
LOOP_{GET,SET}_STATUS, add a separate ioctl just for setting the block
size.

Subject: libnvdimm, nfit: export an 'ecc_unit_size' sysfs attribute

When the nfit driver initializes it runs an ARS (Address Range Scrub)
operation across every pmem range. Part of that process involves
determining the ARS capabilities of a given address range. One of the
capabilities that is reported is the 'Clear Uncorrectable Error Range
Length Unit Size' (see: ACPI 6.2 section 9.20.7.4 Function Index 1 -
Query ARS Capabilities). This property is of interest to userspace
software as it indicates the boundary at which the NVDIMM may need to
perform read-modify-write cycles to maintain ECC blocks.

Subject: libnvdimm, btt: fix a missed NVDIMM_IO_ATOMIC case in the write path

The IO context conversion for rw_bytes missed a case in the BTT write
path (btt_map_write) which should've been marked as atomic.

In reality this should not cause a problem, because map writes are to
small for nsio_rw_bytes to attempt error clearing, but it should be
fixed for posterity.

Add a might_sleep() in the non-atomic section of nsio_rw_bytes so that
things like the nfit unit tests, which don't actually sleep, can catch
bugs like this.

In btt_map_read, we read the map twice to make sure that the map entry

Subject: libnvdimm: fix potential deadlock while clearing errors

With the ACPI NFIT 'DSM' methods, acpi can be called from IO paths.
Specifically, the DSM to clear media errors is called during writes, so
that we can provide a writes-fix-errors model.

However it is easy to imagine a scenario like:
 -> write through the nvdimm driver
   -> acpi allocation
     -> writeback, causes more IO through the nvdimm driver
       -> deadlock

Fix this by using memalloc_noio_{save,restore}, which sets the GFP_NOIO
flag for the current scope when issuing commands/IOs that are expected
to clear errors.

Subject: libnvdimm, btt: rework error clearing

Clearing errors or badblocks during a BTT write requires sending an ACPI
DSM, which means potentially sleeping. Since a BTT IO happens in atomic
context (preemption disabled, spinlocks may be held), we cannot perform
error clearing in the course of an IO. Due to this error clearing for
BTT IOs has hitherto been disabled.

In this patch we move error clearing out of the atomic section, and thus
re-enable error clearing with BTTs. When we are about to add a block to
the free list, we check if it was previously marked as an error, and if
it was, we add it to the freelist, but also set a flag that says error
clearing will be required. We then drop the lane (ending the atomic
context), and send a zero buffer so that the error can be cleared. The
error flag in the free list is protected by the nd 'lane', and is set
only be a thread while it holds that lane. When the error is cleared,
the flag is cleared, but while holding a mutex for that freelist index.

When writing, we check for two things -
1/ If the freelist mutex is held or if the error flag is set. If so,
this is an error block that is being (or about to be) cleared.
2/ If the block is a known badblock based on nsio->bb

The second check is required because the BTT map error flag for a map
entry only gets set when an error LBA is read. If we write to a new
location that may not have the map error flag set, but still might be in
the region's badblock list, we can trigger an EIO on the write, which is
undesirable and completely avoidable.

Subject: libnvdimm, nd_blk: remove mmio_flush_range()

mmio_flush_range() suffers from a lack of clearly-defined semantics,
and is somewhat ambiguous to port to other architectures where the
scope of the writeback implied by "flush" and ordering might matter,
but MMIO would tend to imply non-cacheable anyway. Per the rationale
in 67a3e8fe9015 ("nd_blk: change aperture mapping from WC to WB"), the
only existing use is actually to invalidate clean cache lines for
ARCH_MEMREMAP_PMEM type mappings *without* writeback. Since the recent
cleanup of the pmem API, that also now happens to be the exact purpose
of arch_invalidate_pmem(), which would be a far more well-defined tool
for the job.

Rather than risk potentially inconsistent implementations of
mmio_flush_range() for the sake of one callsite, streamline things by
removing it entirely and instead move the ARCH_MEMREMAP_PMEM related
definitions up to the libnvdimm level, so they can be shared by NFIT
as well. This allows NFIT to be enabled for arm64.

Subject: libnvdimm: fix integer overflow static analysis warning

Dan reports:
    The patch 62232e45f4a2: "libnvdimm: control (ioctl) messages for
    nvdimm_bus and nvdimm devices" from Jun 8, 2015, leads to the
    following static checker warning:

            drivers/nvdimm/bus.c:1018 __nd_ioctl()
            warn: integer overflows 'buf_len'

    From a casual review, this seems like it might be a real bug.  On
    the first iteration we load some data into in_env[].  On the second
    iteration we read a use controlled "in_size" from nd_cmd_in_size().
    It can go up to UINT_MAX - 1.  A high number means we will fill the
    whole in_env[] buffer.  But we potentially keep looping and adding
    more to in_len so now it can be any value.

    It simple enough to change, but it feels weird that we keep looping
    even though in_env is totally full.  Shouldn't we just return an
    error if we don't have space for desc->in_num.

We keep looping because the size of the total input is allowed to be
bigger than the 'envelope' which is a subset of the payload that tells
us how much data to expect. For safety explicitly check that buf_len
does not overflow which is what the checker flagged.

Subject: rtc: ds1307: remove member irq from struct ds1307

The irq number is used in the probe function only, so we don't have
to store it in struct ds1307.

Subject: rtc: ds1307: improve trickle charger initialization

Instead of storing the trickle_charger_setup value in struct chip_desc
we can let function ds1307_trickle_init return it because it's used
in the probe function only.
This allows us to constify struct chip_desc variables in a next step.

Subject: rtc: ds1307: improve irq setup

Change the usage of variable want_irq to reflect its name. Don't set
it to true in case wakeup is enabled but no interrupt number is given.
In addition set variable ds1307_can_wakeup_device if chip->alarm
is set only.
This allows to simplify the code and make it better understandable.

Subject: rtc: ds1307: add basic support for ds1341 chip

This adds support for reading and writing date/time from/to ds1341 chip.

ds1341 chip has other features - alarms, input clock (can be used instead
of intercal oscillator for better accuracy), output clock ("square wave
generation"). However, not all of that is available at the same time.
Same chip pins, CLKIN/nINTA and SQW/nINTB, can be used either for
input/output clocks, or for alarm interrupts. Role of these pins on
particular board depends on hardware wiring.

We can add device tree properties that describe if each of pins is wired
as clock, or as interrupt, or left unconnected, and enable support for
corresponding functionality based on that. But that is cumbersome, requires
hardware for testing, and has to deal with bit enabling/disabling output
clock also affects which pins alarm interrupts are routed to.

Another factor is that there are hardware setups (i.e. ZII RDU2) that
power DS1341 from SuperCap, which makes power saving critical. For such
setups, kernel driver should leave register bits that control mentioned
pins in the state configured by bootloader.

Given all that, it was decided to limit support to "only date/time" for
now. That is enough for common use case. Full (and cumbersome)
implementation can be added later if ever needed.

Subject: rtc: sun6i: Add support for the external oscillator gate

The RTC can output its 32kHz clock outside of the SoC, for example to clock
a WiFi chip.

Create a new clock that other devices will be able to retrieve, while
maintaining the DT stability by providing a default name for that clock if
clock-output-names doesn't list one.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Calls to mmu_notifier_invalidate_page() were replaced by calls to
mmu_notifier_invalidate_range() and are now bracketed by calls to
mmu_notifier_invalidate_range_start()/end()

Remove now useless invalidate_page callback.

The RK808 and RK805 PMICs are using a similar register map.
We can reuse the clk driver for the RK805 PMIC. So let's add
the RK805 in the Kconfig description.

Subject: Thermal: int3406_thermal: fix thermal sysfs I/F

there are three concepts represent backlight in int3406_thermal driver.
1. the raw brightness value from native graphics driver.
2. the percentage numbers from ACPI _BCL control method.
3. the consecutive numbers represent cooling states.

int3406_thermal driver
1. uses value from DDDL/DDPC as the lower/upper limit, which is consistent
   with ACPI _BCL control methods.
2. reads current and maximum brightness from the native graphics driver.
3. expose them to thermal sysfs I/F

This patch fixes the code that switches between the raw brightness value
and the cooling state, which results in bogus value in thermal sysfs I/F.

Subject: clk: hi6220: change watchdog clock source

The old code uses tcxo (19.2MHz) as watchdog clock but actually the
watchdog uses 32K clock, as result the watchdog timeout cannot be set
correctly and delay long time to reset SoC.

So this patch is to use 'ref32k' as clock source for watchdog.

Subject: clk: nxp: clk-lpc32xx: rename clk_gate_is_enabled()

We need to export clk_gate_is_enabled() from clk framework, then
to avoid compilation issue we have to rename clk_gate_is_enabled()
in NXP LPC32xx clock driver.
We changed all gate op with 'lpc32xx_' prefix:
lpc32xx_clk_gate_enable(),
lpc32xx_clk_gate_disable(),
lpc32xx_clk_gate_is_enabled().

+STMicroelectronics STM32H7 Reset and Clock Controller
+=====================================================
+
+The RCC IP is both a reset and a clock controller.
+
+Please refer to clock-bindings.txt for common clock controller binding usage.
+Please also refer to reset.txt for common reset controller binding usage.
+
+Required properties:
+- compatible: Should be:
+  "st,stm32h743-rcc"
+
+- reg: should be register base and length as documented in the
+  datasheet
+
+- #reset-cells: 1, see below
+
+- #clock-cells : from common clock binding; shall be set to 1
+
+- clocks: External oscillator clock phandle
+  - high speed external clock signal (HSE)
+  - low speed external clock signal (LSE)
+  - external I2S clock (I2S_CKIN)
+
+Optional properties:
+- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
+  write protection (RTC clock).
+
+Example:
+
+	rcc: reset-clock-controller@58024400 {
+		compatible = "st,stm32h743-rcc", "st,stm32-rcc";
+		reg = <0x58024400 0x400>;

+		clocks = <&clk_hse>, <&clk_lse>, <&clk_i2s_ckin>;
+
+		st,syscfg = <&pwrcfg>;
+};
+
+The peripheral clock consumer should specify the desired clock by
+having the clock ID in its "clocks" phandle cell.
+
+Example:
+
+		timer5: timer@40000c00 {
+			compatible = "st,stm32-timer";
+			reg = <0x40000c00 0x400>;
+			interrupts = <50>;
+			clocks = <&rcc TIM5_CK>;
+		};
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use.
+The index is the bit number within the RCC registers bank, starting from RCC
+base address.
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register.
+
+For example, for CRC reset:
+  crc = AHB4RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x88 / 4 * 32 + 19 = 1107
+
+Example:
+
+	timer2 {
+		resets	= <&rcc STM32H7_APB1L_RESET(TIM2)>;
+	};

Subject: clk: ti: check for null return in strrchr to avoid null dereferencing

strrchr can potentially return a null so the following strlen on the
null pointer can cause a null dereference. Add a check to see if
the string postfix is not null before calling strlen.

If a pass-through request is submitted then blk_get_request()
initializes that request by calling scsi_initialize_rq(). Also call this
function for filesystem requests. Introduce CMD_INITIALIZED to keep
track of whether or not a request has already been initialized.

Subject: scsi: Improve requeuing behavior

Requests are unprepared and reprepared when being requeued.  Avoid that
requeuing resets .jiffies_at_alloc and .retries by initializing these
two member variables from inside scsi_initialize_rq() and by preserving
both member variables when preparing a request. This patch affects the
requeuing behavior of both the legacy scsi and the scsi-mq code paths.

Subject: scsi: scsi-mq: Always unprepare before requeuing a request

One of the two scsi-mq functions that requeue a request unprepares a
request before requeueing (scsi_io_completion()) but the other function
not (__scsi_queue_insert()). Make sure that a request is unprepared
before requeuing it.

Subject: md/bitmap: disable bitmap_resize for file-backed bitmaps.

bitmap_resize() does not work for file-backed bitmaps.
The buffer_heads are allocated and initialized when
the bitmap is read from the file, but resize doesn't
read from the file, it loads from the internal bitmap.
When it comes time to write the new bitmap, the bh is
non-existent and we crash.

The common case when growing an array involves making the array larger,
and that normally means making the bitmap larger.  Doing
that inside the kernel is possible, but would need more code.
It is probably easier to require people who use file-backed
bitmaps to remove them and re-add after a reshape.

So this patch disables the resizing of arrays which have
file-backed bitmaps.  This is better than crashing.

Reported-by: Zhilong Liu <zlliu@suse.com>
Fixes: d60b479d177a ("md/bitmap: add bitmap_resize function to allow bitmap resizing.")

Subject: crypto/nx: Add P9 NX support for 842 compression engine

This patch adds P9 NX support for 842 compression engine. Virtual
Accelerator Switchboard (VAS) is used to access 842 engine on P9.

For each NX engine per chip, setup receive window using
vas_rx_win_open() which configures RxFIFo with FIFO address, lpid,
pid and tid values. This unique (lpid, pid, tid) combination will
be used to identify the target engine.

For crypto open request, open send window on the NX engine for
the corresponding chip / cpu where the open request is executed.
This send window will be closed upon crypto close request.

NX provides high and normal priority FIFOs. For compression /
decompression requests, we use only hight priority FIFOs in kernel.

Each NX request will be communicated to VAS using copy/paste
instructions with vas_copy_crb() / vas_paste_crb() functions.

Subject: ide: pmac: Convert to using %pOF instead of full_name

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Subject: powerpc/macintosh: constify wf_sensor_ops structures

The wf_sensor_ops structures are only stored in the ops field of a
wf_sensor structure, which is declared as const.  Thus the
wf_sensor_ops structures themselves can be const.

Done with the help of Coccinelle.

Subject: ANDROID: binder: remove proc waitqueue

Removes the process waitqueue, so that threads
can only wait on the thread waitqueue. Whenever
there is process work to do, pick a thread and
wake it up. Having the caller pick a thread is
helpful for things like priority inheritance.

This also fixes an issue with using epoll(),
since we no longer have to block on different
waitqueues.

Subject: ANDROID: binder: push new transactions to waiting threads.

Instead of pushing new transactions to the process
waitqueue, select a thread that is waiting on proc
work to handle the transaction. This will make it
easier to improve priority inheritance in future
patches, by setting the priority before we wake up
a thread.

If we can't find a waiting thread, submit the work
to the proc waitqueue instead as we did previously.

Subject: ANDROID: binder: Add BINDER_GET_NODE_DEBUG_INFO ioctl

The BINDER_GET_NODE_DEBUG_INFO ioctl will return debug info on
a node.  Each successive call reusing the previous return value
will return the next node.  The data will be used by
libmemunreachable to mark the pointers with kernel references
as reachable.

Subject: ANDROID: binder: Don't BUG_ON(!spin_is_locked()).

Because is_spin_locked() always returns false on UP
systems.

Use assert_spin_locked() instead, and remove the
WARN_ON() instances, since those were easy to verify.

Subject: ANDROID: binder: don't enqueue death notifications to thread todo.

This allows userspace to request death notifications without
having to worry about getting an immediate callback on the same
thread; one scenario where this would be problematic is if the

Subject: ANDROID: binder: don't queue async transactions to thread.

This can cause issues with processes using the poll()
interface:

1) client sends two oneway transactions
2) the second one gets queued on async_todo
   (because the server didn't handle the first one
    yet)
3) server returns from poll(), picks up the
   first transaction and does transaction work
4) server is done with the transaction, sends
   BC_FREE_BUFFER, and the second transaction gets
   moved to thread->todo
5) libbinder's handlePolledCommands() only handles
   the commands in the current data buffer, so
   doesn't see the new transaction
6) the server continues running and issues a new
   outgoing transaction. Now, it suddenly finds
   the incoming oneway transaction on its thread
   todo, and returns that to userspace.
7) userspace does not expect this to happen; it
   may be holding a lock while making the outgoing
   transaction, and if handling the incoming
   trasnaction requires taking the same lock,
   userspace will deadlock.

By queueing the async transaction to the proc
workqueue, we make sure it's only picked up when
a thread is ready for proc work.

Subject: of: restrict DMA configuration

Moving DMA configuration to happen later at driver probe time had the
unnoticed side-effect that we now perform DMA configuration for *every*
device represented in DT, rather than only those explicitly created by
the of_platform and PCI code.

As Christoph points out, this is not really the best thing to do. Whilst
there may well be other DMA-capable buses that can benefit from having
their children automatically configured after the bridge has probed,
there are also plenty of others like USB, MDIO, etc. that definitely do
not support DMA and should not be indiscriminately processed.

The good news is that in most cases the DT "dma-ranges" property serves
as an appropriate indicator - per a strict interpretation of the spec,
anything lacking a "dma-ranges" property should be considered not to
have a mapping of DMA address space from its children to its parent,
thus anything for which of_dma_get_range() does not succeed does not
need DMA configuration. Certain bus types have a general expectation of
DMA capability and carry a well-established precedent that an absent
"dma-ranges" implies the same as the empty property, so we automatically
opt those in to DMA configuration regardless, to avoid regressing most
existing platforms.

Subject: spi: spi-falcon: drop check of boot select

Do not check which flash type the SoC was booted from before
using this driver. Assume that the device tree is correct and use this
driver when it was added to device tree. This also removes a build
dependency to the SoC code.

All device trees I am aware of only have one correct flash device entry
in it. The device tree is anyway bundled with the kernel in all systems
using device tree I know of.

The boot mode can be specified with some pin straps and will select the
flash type the rom code will boot from. One SPI, NOR or NAND flash chip
can be connect to the EBU and used to load the first stage boot loader
from.

Subject: block/loop: set hw_sectors

Loop can handle any size of request. Limiting it to 255 sectors just
burns the CPU for bio split and request merge for underlayer disk and
also cause bad fs block allocation in directio mode.

Subject: block/loop: allow request merge for directio mode

Currently loop disables merge. While it makes sense for buffer IO mode,
directio mode can benefit from request merge. Without merge, loop could
send small size IO to underlayer disk and harm performance.

Subject: mlxsw: spectrum: Forbid linking to devices that have uppers

The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the
device in case a port is enslaved to a master netdev such as bridge or
bond.

Since the driver ignores events unrelated to its ports and their
uppers, it's possible to engineer situations in which the device's data
path differs from the kernel's.

One example to such a situation is when a port is enslaved to a bond
that is already enslaved to a bridge. When the bond was enslaved the
driver ignored the event - as the bond wasn't one of its uppers - and
therefore a bridge port instance isn't created in the device.

Until such configurations are supported forbid them by checking that the
upper device doesn't have uppers of its own.

Subject: mlxsw: spectrum_router: Trap packets hitting anycast routes

I relied on the fact that anycast routes use the loopback device as
their nexthop device to trap packets hitting them to the CPU.

After commit 4832c30d5458 ("net: ipv6: put host and anycast routes on
device with address") this is no longer the case and such routes are
programmed with a forward action (note the 'offload' flag):

anycast cafe:: dev enp3s0np7 proto kernel metric 0 offload pref medium

This will prevent the router from locally receiving packets destined to
the Subnet-Router anycast address.

Fix this by specifically programming anycast routes with action trap,
which results in the following output:

anycast cafe:: dev enp3s0np7 proto kernel metric 0 pref medium

Subject: mlxsw: spectrum_router: Set abort trap in all virtual routers

When the abort mechanism is invoked a default route directing packets to
the CPU is programmed in all the virtual routers currently in use. This
can result in packet loss in case a new VRF is configured.

Upon abort, program the default route in all virtual routers, whether
they are in use or not.

The patch is directed at net-next since post-abort fixes aren't critical
and packet loss due to a missing default route will be insignificant
compared to packet loss caused by the CPU port policer.

Subject: net: mvpp2: make the phy optional

There is not necessarily a PHY between the GoP and the physical port.
However, the driver currently makes the "phy" property mandatory,
contrary to what is stated in the device tree bindings. This patch makes
the PHY optional, and aligns the PPv2 driver on its device tree
documentation. However if a PHY is provided, the GoP link interrupt
won't be used.

With this patch switches directly connected to the serdes lanes and SFP
ports on the Armada 8040-db and Armada 7040-db can be used if the link
interrupt is described in the device tree.

Subject: net: mvpp2: use the GoP interrupt for link status changes

This patch adds the GoP link interrupt support for when a port isn't
connected to a PHY. Because of this the phylib callback is never called
and the link status management isn't done. This patch use the GoP link
interrupt in such cases to still have a minimal link management. Without
this patch ports not connected to a PHY cannot work.

Subject: net: mdio-mux: fix unbalanced put_device

mdio_mux_uninit() call put_device (unconditionally) because of
of_mdio_find_bus() in mdio_mux_init.
But of_mdio_find_bus is only called if mux_bus is empty.
If mux_bus is set, mdio_mux_uninit will print a "refcount_t: underflow"
trace.

This patch add a get_device in the other branch of "if (mux_bus)".

 timeouts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes the DP AUX CH timeouts observed during CI runs causing
CI Failures on a specific PCI device. This issue was fixed previously
by adding a quirk but looks like we need to increase this delay even more
in order to get rid all the DP AUX CH timeouts.

Subject: qlcnic: remove redundant zero check on retries counter

At the end of the do while loop the integer counter retries will
always be zero and so the subsequent check to see if it is zero
is always true and therefore redundant.  Remove the redundant check
and always return -EIO on this return path.  Also unbreak the literal
string in dev_err message to clean up a checkpatch warning.

Subject: mvneta: Driver and hardware supports IPv6 offload, so enable it

The mvneta driver and hardware supports IPv6 offload, however it
isn't enabled. Set the NETIF_F_IPV6_CSUM feature to inform the
network layer that this driver can offload IPV6 TCP and UDP
checksums. This change has been tested on an Armada 370 and the
feature support confirmed with several device datasheets
including the Armada XP and Armada 3700.

Subject: clk: at91: clk-generated: remove useless divisor loop

The driver requests the current clk rate of each of its parent clocks to
decide whether a clock rate is suitable or not. It does not request
determine_rate from a parent clock which could request a rate change in
parent clock (i.e. there is no parent rate propagation).

We know the rate we want (passed along req argument of the function) and
the parent clock rate, thus we know the closest rounded divisor, we
don't need to iterate over the available divisors to find the best one
for a given clock.

Subject: clk: at91: add audio pll clock drivers

This new clock driver set allows to have a fractional divided clock that
would generate a precise clock particularly suitable for audio
applications.

The main audio pll clock has two children clocks: one that is connected
to the PMC, the other that can directly drive a pad. As these two routes
have different enable bits and different dividers and divider formulas,
they are handled by two different drivers. Each of them could modify the
rate of the main audio pll parent.

The main audio pll clock can output 620MHz to 700MHz.

Subject: clk: at91: clk-generated: create function to find best_diff

The way to find the best_diff and do the appropriate process afterwards
can be re-used.

This patch prepares the driver for an upcoming patch that will allow
clk_generated to determine the rate of the audio_pll.

Subject: clk: at91: clk-generated: make gclk determine audio_pll rate

This allows gclk to determine audio_pll rate and set the parent rate
accordingly.

However, there are multiple children clocks that could technically
change the rate of audio_pll (via gck). With the rate locking, the first
consumer to enable the clock will be the one definitely setting the rate
of the clock.

Since audio IPs are most likely to request the same rate, we enforce
that the only clks able to modify gck rate are those of audio IPs.

To remain consistent, we deny other clocks to be children of audio_pll.

fatal error is detected. Introduce an interface that walks the device
tree in search for a remoteproc instance and return this.

Subject: clk: si5351: fix PLL reset

Changing the audio sample rate on the SolidRun Cubox disrupts the video
output.  The Si5351 provides both the video clock (using PLLA on output
0) and the audio clock (using PLLB on output 2).

When the rate of clock output 2 is changed, it reconfigures PLLB, which
results in both PLLA and PLLB being reset.  The reset of PLLA causes
clock output 0 to be disrupted, thereby causing a loss of sync by the
attached display device.

Hence, each time the audio sample rate changes (eg, when a video player
starts up, or when starting to play music) the video display momentarily
blanks while the Si5351 settles down.  Prior to the commit below, this
behaviour did not happen.

Fix this by only resetting only the PLL which has been changed.

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

Subject: netvsc: allow driver to be removed even if VF is present

If VF is attached then can still allow netvsc driver module to
be removed. Just have to make sure and do the cleanup.

Also, avoid extra rtnl round trip when calling unregister.

Subject: hv_netvsc: Simplify the limit check in netvsc_set_channels()

Because of the following code, net->num_tx_queues equals to
VRSS_CHANNEL_MAX, and max_chn is less than or equals to VRSS_CHANNEL_MAX.

netvsc_drv.c:
alloc_etherdev_mq(sizeof(struct net_device_context),
                                VRSS_CHANNEL_MAX);
rndis_filter.c:
net_device->max_chn = min_t(u32, VRSS_CHANNEL_MAX, num_possible_rss_qs);

So this patch removes the unnecessary limit check before comparing
with "max_chn".

Subject: net/mlx5e: Small enhancements for RX MPWQE allocation and free

The dma offset of a MPWQE (Multi-Packet WQE) in memory region
is fixed for all rounds. Calculate it once on creation time,
instead of in runtime. This also obsoletes the wqe argument in
the function.

In addition, optimize dma_info iterator calculation.

as possible.

Subject: net/mlx5e: Early-return on empty completion queues

NAPI context handles different kinds of completion queues
(RX, TX, and others). Hence, upon a poll trial, some of them
might be empty.
Here we early-return upon empty completion queues, as well as
full rx buffer, and save unnecessary logic and memory barriers.

Subject: net/mlx5e: Non-atomic indicator for ring enabled state

Rings enabled state change occurs in control path only, and is always
followed by a napi_sychronize(), so that following NAPIs read the
new value. This read does not need to be atomic.

The RQ auto-moderation bit is not set/cleared in data-path.
No need for atomic read, a regular read operation is sufficient.
In RQ creation time as well, there's no multiple threads trying
to access it yet, hence a regular read can be used.

Subject: net/mlx5e: Non-atomic RQ state indicator for UMR WQE in progress

The indication for a UMR WQE in progress is needed only within
the NAPI context, and hence no races possible and no need for
the use of atomic operations.
The only place the flag is read outside of NAPI context is
in closure flow, after RQ is disabled flag is no more accessed
in NAPI.
Use a boolean instead of a bit in ring state, so that its
non-atomic set operations do not race with the atomic sets of
the other bits.

Separate the RX post WQEs function of the different RQ types.
This enables RQ type-specific optimizations in data-path.

Poll the ICOSQ completion queue only for Striding RQ,
and only when a UMR post completion could be possibly available.

Subject: net/mlx5e: Remove unnecessary fields in ICO SQ

As of current design, in each NAPI, only a single UMR WQE
completion could be available in the completion queue of the
the internal control operations (ICO) send queue, in addition
to nop operations that require no actions upon completion.
This renders the consume index obsolete, as the wqe_counter
field in CQE is sufficient.

This helps removing a memory barrier, and obsoletes the need
for tracking the num_wqebbs to update the consumer counter.

In addition, remove other unused fields in icosq struct:
pdev, dma_fifo_pc, and prev_cc.

Subject: net/mlx5e: Slightly increase RX page-cache size

In XDP_TX flow, we now get back quicker to each page in page-cache,
and on some occasions refcount does not get back to 1 on time, causing
some costly page allocations.
Slightly increase the size of RX page-cache to significantly decrease
the chances for this to happen.

Subject: net/mlx5e: Use kernel's mechanism to avoid missing NAPIs

We used a channel state bit MLX5E_CHANNEL_NAPI_SCHED to make
sure no NAPI is missed when a channel's napi_schedule() is called
for completion events of the different channel's resources/rings
while NAPI is currently running.
Now, as similar mechanism is implemented in kernel,
("39e6c8208d7b net: solve a NAPI race"),
we obsolete our own implementation and rely on the return value
of napi_complete_done().

This patch removes a redundant overhead of atomic bit operations.

Subject: net/mlx5e: Stop NAPI when irq balancer changes affinity

NAPI context keeps rescheduling on same CPU as long as it's busy.
This doesn't give the oppurtunity for changes in irq affinities
to take effect.
Fix that by calling napi_complete_done() upon a change in affinity.
This would stop the NAPI and reschedule it on the new CPU.

Subject: net/mlx5e: Distribute RSS table among all RX rings

In default, uniformly distribute the RSS indirection table entries
among all RX rings, rather than restricting this only to the rings
on the close NUMA node. irqbalancer would anyway dynamically override
the default affinities set to the RX rings.
This gives better multi-stream performance and CPU util.

Subject: net/mlx4_core: fix memory leaks on error exit path

The structures hca_param and func_cap are not being kfree'd on an error
exit path causing two memory leaks. Fix this by jumping to the existing
free memory error exit path.

Subject: net: mvpp2: fix use of the random mac address for PPv2.2

The MAC retrieval logic is using a variable to store an h/w stored mac
address and checks this mac against invalid ones before using it. But
the mac address is only read from h/w when using PPv2.1. So when using
PPv2.2 it defaults to its init state.

This patches fixes the logic to only check if the h/w mac is valid when
actually retrieving a mac from h/w.

 valid

When using a mac address described in the device tree, a check is made
to see if it is valid. When it's not, no fallback is defined. This
patches tries to get the mac address from h/w (or use a random one if
the h/w one isn't valid) when the dt mac address isn't valid.

During error injection it was possible to crash in dsa_loop_exit() because of

in dsa_loop_init() even though fixed_phy_register() may return an error to
exercise how DSA deals with such cases, but we should not be crashing during
driver removal.

So far, adjacencies have always been of type Ethernet (with value of 0),
and thus there was no need to explicitly support RATR type. However to
support IP-in-IP adjacencies, this type and a suite of IP-in-IP-specific
attributes need to be added.

To implement IP-in-IP decapsulation, Spectrum uses LPM entries of type
IP2ME with tunnel validity bit and tunnel pointer set. The necessary
register fields are already available, so add a function to pack the
RALUE as appropriate.

Subject: mlxsw: spectrum_router: Add mlxsw_sp_ipip_ops

Details of individual tunnel types are kept in an array of
mlxsw_sp_ipip_ops objects. Follow-up patches will use the list to
determine whether a constructed RIF should be a loopback, and to decide
whether a next hop references a tunnel.

The list is currently empty, follow-up patches will add support for GRE.

Subject: mlxsw: spectrum_router: Support FID-less RIFs

Loopback RIFs, which will be introduced in a follow-up patch, differ
from other RIFs in that they do not have a FID associated with them.

To support this, demote FID allocation from mlxsw_sp_rif_create to
configure op of the existing RIF types, and likewise the FID release
from mlxsw_sp_rif_destroy to deconfigure op.

Subject: mlxsw: spectrum_router: Introduce loopback RIFs

When offloading L3 tunnels, an adjacency entry is created that loops the
packet back into the underlay router. Loopback interfaces then hold the
corresponding information and are created for IP-in-IP netdevices.

Subject: mlxsw: spectrum_router: Extract mlxsw_sp_fi_is_gateway()

For IPv4 IP-in-IP offload, routes that direct traffic to IP-in-IP
devices need to be considered gateway routes as well. That involves a
bit more logic, so extract the current test to a separate function,
where the logic can be later added.

Subject: mlxsw: spectrum_router: Extract mlxsw_sp_rt6_is_gateway()

IPv6 counterpart of the previous patch: introduce a function to
determine whether a given route is a gateway route.

The new function takes a mlxsw_sp argument which follow-up patches will
use. Thus mlxsw_sp_fib6_entry_type_set() got that argument as well.

Subject: mlxsw: spectrum_router: Make nexthops typed

In the router, some next hops may reference an encapsulating netdevice,
such as GRE or IPIP. To properly offload these next hops, mlxsw needs to
keep track of whether a given next hop is a regular Ethernet entry, or
an IP-in-IP tunneling entry.

To facilitate this book-keeping, add a type field to struct
mlxsw_sp_nexthop. There is, as of this patch, only one next hop type:
MLXSW_SP_NEXTHOP_TYPE_ETH. Follow-up patches will introduce the IP-in-IP
variant.

There are several places where next hops are initialized in the IPv4
path. Instead of replicating the logic at every one of them, factor it
out to a function mlxsw_sp_nexthop4_type_init(). The corresponding fini
is actually protocol-neutral, so put it to mlxsw_sp_nexthop_type_fini(),
but create a corresponding protocoled _fini function that dispatches to
the protocol-neutral one.

The IPv6 path is simpler, but for symmetry with IPv4, create the same
suite of functions with corresponding logic.

From 1012b9ac28c6d61f54e0dd9f8744af88427020b7 Mon Sep 17 00:00:00 2001
From: Petr Machata <petrm@mellanox.com>

Subject: mlxsw: spectrum_router: Support IPv4 overlay encap

This introduces some common code for tracking of offloaded IP-in-IP
tunnels, and support for offloading IPv4 overlay encapsulating routes in
particular. A follow-up patch will introduce IPv6 overlay as well.

Offloaded tunnels are kept in a linked list of mlxsw_sp_ipip_entry
objects hooked up in mlxsw_sp_router. A network device that represents
the tunnel is used as a key to look up the corresponding IPIP entry.
Note that in the future, more general keying mechanism will be needed,
because parts of the tunnel information can be provided by the route.

IPIP entries are reference counted, because several next hops may end up
using the same tunnel, and we only want to offload it once.

Encapsulation path hooks into next hop handling. Routes that forward to
a tunnel are now considered gateway routes, thus giving them the same
treatment that other remote routes get. An IPIP next hop type is
introduced.

Details of individual tunnel types are kept in an array of
mlxsw_sp_ipip_ops objects. If a tunnel type doesn't match any of the
known tunnel types, the next-hop is not considered an IPIP next hop.

The list of IPIP tunnel types is currently empty, follow-up patches will
add support for GRE. Traffic to IPIP tunnel types that are not
explicitly recognized by the driver traps and is handled in slow path.

Subject: mlxsw: spectrum_router: Support IPv4 underlay decap

Unlike encapsulation, which is represented by a next hop forwarding to
an IPIP tunnel, decapsulation is a type of local route. It is created
for local routes whose prefix corresponds to the local address of one of
offloaded IPIP tunnels. When the tunnel is removed (i.e. all the encap
next hops are removed), the decap offload is migrated back to a trap for
resolution in slow path.

This patch assumes that decap route is already present when encap route
is added. A follow-up patch will fix this issue.

Note that this patch only supports IPv4 underlay. Support for IPv6
underlay will be subject to follow-up work apart from this patchset.

Subject: mlxsw: spectrum_router: Use existing decap route

The local route that points at IPIP's underlay device (decap route) can
be present long before the GRE device. Thus when an encap route is
added, it's necessary to look inside the underlay FIB if the decap route
is already present. If so, the current trap offload needs to be
withdrawn and replaced with a decap offload.

Subject: mlxsw: spectrum: Register for IPIP_DECAP_ERROR trap

These traps are generated for packets that fail checks for source IP,
encapsulation type, or GRE key. Trap these packets to CPU for follow-up
handling by the kernel, which will send ICMP destination unreachable
responses.

Subject: mlxsw: spectrum_router: Add loopback accessors

struct mlxsw_sp_rif is a router-private structure, and therefore
everything related to it is as well: parameters, and derived RIF types
including loopbacks. IPIP module needs access to some details of
loopback interfaces, but exporting all the RIF shebang would create too
large an interface.

So instead export just the bare minimum necessary: accessors for RIF
index and underlay VRF ID.

From c496291c5a414bd55bae76880137947d2e8decbe Mon Sep 17 00:00:00 2001

Subject: nfp: separate app vNIC init/clean from alloc/free

We currently only have one app callback for vNIC creation
and destruction.  This is insufficient, because some actions
have to be taken before netdev is registered, after it's
registered and after it's unregistered.  Old callbacks
were really corresponding to alloc/free actions.  Rename
them and add proper init/clean.  Apps using representors
will be able to use new callbacks to manage lifetime of
upper devices.

Subject: nfp: flower: base lifetime of representors on existence of lower vNIC

Create representors after lower vNIC is registered and destroy
them before it is destroyed.  Move the code out of start/stop
callbacks directly into vnic_init/clean callbacks.  Make sure
SR-IOV callbacks don't try to create representors when lower
device does not exist.

Subject: nfp: move the start/stop app callbacks back

Since representors are now created with a separate callback
start/stop app callbacks can be moved again to their original
location.  They are intended to app-specific init/clean up
over the control channel.

Subject: nfp: flower: restore RTNL locking around representor updates

When we moved to updating representors from a workqueue grabbing
the RTNL somehow got lost in the process.  Restore it, and make
sure RCU lock is not held while we are grabbing the RTNL.  RCU
protects the representor table, so since we will be under RTNL
we can drop RCU lock as soon as we find the netdev pointer.
RTNL is needed for the dev_set_mtu() call.

Subject: net: qualcomm: rmnet: Refactor the new rmnet dev creation

Data format can be directly set from rmnet_newlink() since the
rmnet real dev info is already available.

Since __rmnet_get_real_dev_info() is no longer used in rmnet_config.c
after removal of those functions, move content to
rmnet_get_real_dev_info().

__rmnet_set_endpoint_config() is collapsed into
rmnet_set_endpoint_config() since only mux_id was being set additionally
within it. Remove an unnecessary mux_id check.

Set the mux_id for the rmnet_dev within rmnet_vnd_newlink() itself.

Subject: irqchip: mips-gic: Simplify shared interrupt pending/mask reads

Simplify the reads of the bitmaps indicating pending & masked interrupts
in gic_handle_shared_int() using the __ioread32_copy() &
__ioread64_copy() helper functions.

Subject: irqchip: mips-gic: Simplify gic_local_irq_domain_map()

Simplify gic_local_irq_domain_map() by:

- Moving the check for invalid IRQs outside of the loop.

- Moving the decision about whether to use gic_cpu_pin or timer_cpu_pin
  outside of the loop.

- Using the new write_gic_vo_map() accessor function to avoid the need
  to handle each map register separately.

Subject: irqchip: mips-gic: Drop gic_(re)set_mask() functions

The gic_set_mask() & gic_reset_mask() functions are now no more
convenient to call than the write_gic_smask() or write_gic_rmask()
accessor functions. Remove the layer of abstraction.

Subject: irqchip: mips-gic: Remove gic_set_dual_edge()

Remove the gic_set_dual_edge() function in favour of using the new
change_gic_dual() accessor function which provides equivalent
functionality. This also allows us to remove the gic_update_bits()
function which gic_set_dual_edge() was the last user of, along with the
GIC_INTR_OFS() & GIC_INTR_BIT() macros.

Convert the remaining accesses to registers in the GIC shared register
block to use the new accessor functions provided by asm/mips-gic.h,
resulting in code which is often shorter & easier to read.

Subject: irqchip: mips-gic: Convert local int mask access to new accessors

Use the new accessor functions provided by asm/mips-gic.h to access
masks controlling local interrupts, resulting in code which is often
shorter & easier to read.

From: Paul Burton <paul.burton@imgtec.com>

Subject: irqchip: mips-gic: Move various definitions to the driver

Move the definitions of macros used to convert between hardware IRQ
numbers & shared or local interrupt numbers into the irqchip driver,
which is all that should ever need to care about them.

Remove GIC_CPU_TO_VEC_OFFSET() in the process since it's never used.

Subject: irqchip: mips-gic: Remove gic_get_usm_range()

The MIPS VDSO code is no longer reliant upon the irqchip driver to
provide the address of the GIC's user-visible section via
gic_get_usm_range(). Remove the now-dead code.

Subject: irqchip: mips-gic: Move gic_get_c0_*_int() to asm/mips-gic.h

The linux/irqchip/mips-gic.h header is now almost empty. Move the
declarations of gic_get_c0_compare_int(), gic_get_c0_perfcount_int() &
gic_get_c0_fdc_int() to asm/mips-gic.h in order to close in on being
able to delete the former header.

Subject: irqchip: mips-gic: Inline __gic_init()

The __gic_init() function is only called from gic_of_init() now that the
non-DT path has been removed. In order to simplify the code & aid
readability, fold __gic_init() into gic_of_init().

This provides us with the ability to return an error code, which
__gic_init() was previously unable to do. As such the irq_domain_add_*()
error paths are modified to print & return an error rather than panic().

[ralf@linux-mips.org: Resoled reject.]

Subject: irqchip: mips-gic: Use pcpu_masks to avoid reading GIC_SH_MASK*

This patch avoids the need to read the GIC_SH_MASK* registers when
decoding shared interrupts by setting & clearing the interrupt's bit in
the appropriate CPU's pcpu_masks entry when masking or unmasking the
interrupt.

This effectively means that whilst an interrupt is masked we clear its
bit in all pcpu_masks, which causes gic_handle_shared_int() to ignore it
on all CPUs without needing to check GIC_SH_MASK*.

In essence, we add a little overhead to masking or unmasking interrupts
but in return reduce the overhead of the far more common task of
decoding interrupts.

Subject: irqchip: mips-gic: Clean up mti, reserved-cpu-vectors handling

When parsing mti,reserved-cpu-vectors we generate a mask of all bits
that have been declared reserved, the loop through starting from bit 2
to find one that isn't reserved (ie. is zero).

This patch accomplishes the same task more simply by:

  - Inititialising the reserved mask to 0x3 (ie. the 2 software
    interrupts). This means we don't need to skip them later as the loop
    previously has.

  - Replacing the loop checking for zero bits with find_first_zero_bit,
    which fits our needs now that the 2 software interrupts are marked
    reserved. This requires that the type of reserved is changed to
    unsigned long so that it's suitable for use with bitmap functions.

  - Replacing the magic number 8 with the hamming weight of the ST0_IM
    field - ie. the number of bits that a MIPS CPU has for interrupt
    inputs. This is still a compile-time constant 8, but makes it
    clearer why it's 8.

Subject: irqchip: mips-gic: Use cpumask_first_and() in gic_set_affinity()

Currently in gic_set_affinity() we calculate a temporary cpumask holding
the intersection of the provided cpumask & the CPUs that are online,
then we call cpumask_first twice on it to find the first such CPU. Since
we don't need the temporary cpumask for anything else & we only care
about the first CPU that's both online & in the provided cpumask, we can
instead use cpumask_first_and to find that CPU & drop the temporary
mask.

Subject: irqchip: mips-gic: Let the core set struct irq_common_data affinity

gic_set_affinity() manually copies the provided cpumask to the struct
irq_common_data affinity field, returning IRQ_SET_MASK_OK_NOCOPY in
order to prevent the core code from doing that.

We can instead simply let the core code do it for us, by returning
IRQ_SET_MASK_OK instead of IRQ_SET_MASK_OK_NOCOPY & doing the copy
ourselves.

Subject: mtd: lantiq-flash: drop check of boot select

Do not check which flash type the SoC was booted from before
using this driver. Assume that the device tree is correct and use this
driver when it was added to device tree. This also removes a build
dependency to the SoC code.

Subject: watchdog: lantiq: access boot cause register through regmap

This patch avoids accessing the function ltq_reset_cause() and directly
accesses the register given over the syscon interface. The syscon
interface will be implemented for the xway SoCs for the falcon SoCs the
ltq_reset_cause() function never worked, because a wrong offset was used.

Subject: mfd: Add STM32 LPTimer driver

STM32 Low-Power Timer hardware block can be used for:
- PWM generation
- IIO trigger (in sync with PWM)
- IIO quadrature encoder counter
PWM and IIO timer configuration are mixed in the same registers so
we need a multi fonction driver to be able to share those registers.

Subject: iio: trigger: Add STM32 LPTimer trigger driver

Add support for LPTIMx_OUT triggers that can be found on some STM32
devices. These triggers can be used then by ADC or DAC.
Typical usage is to configure LPTimer as PWM output (via pwm-stm32-lp)
and have synchronised analog conversions with these triggers.

Subject: iio: adc: stm32: add support for lptimer triggers

STM32 ADC supports hardware triggers like STM32 Low-Power Timer.
For instance, STM32H7 ADC may be triggered by instances 1, 2 or 3.
Add hardware triggered mode so Low-Power Timer Trigger driver can
validate device.

Subject: video: fbdev: annotate fb_fix_screeninfo with const and __initconst

Make these const as they are only used during a copy operation.
Some structures are used as a copy operation inside __init functions, so
make them const and replace __initdata with __initconst to avoid section
conflict error.

This removes the restriction on the value range of the fbcon=margin:

Subject: vgacon: Prevent faulty bootparams.screeninfo from causing harm
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If a zero for the number of colums or rows manages to slip through,
gotoxy() will underflow vc->vc_pos, causing the next action on the
referenced memory to end with a page fault.

Make the check in vgacon_startup() more pessimistic to prevent that.

Subject: video: fbdev: aty: do not leak uninitialized padding in clk to
 userspace

'clk' is copied to a userland with padding byte(s) after 'vclk_post_div'
field unitialized, leaking data from the stack. Fix this ensuring all of
'clk' is initialized to zero.

In the case where glink->intentless is true and the call
to qcom_glink_tx fails then we have a condition where ret is
non-zero and intent is null, causing a null pointer deference
when setting intent->in_use to false.  Add an extra check to
only dereference intent if intent is non-null.

Subject: libnvdimm, nfit: move the check on nd_reserved2 to the endpoint

Delay the check of nd_reserved2 to the actual endpoint (acpi_nfit_ctl)
that uses it, as a prevention of a potential double-fetch bug.

While examining the kernel source code, I found a dangerous operation that
could turn into a double-fetch situation (a race condition bug) where
the same userspace memory region are fetched twice into kernel with sanity
checks after the first fetch while missing checks after the second fetch.

In the case of _IOC_NR(ioctl_cmd) == ND_CMD_CALL:

1. The first fetch happens in line 935 copy_from_user(&pkg, p, sizeof(pkg)

2. subsequently `pkg.nd_reserved2` is asserted to be all zeroes
(line 984 to 986).

3. The second fetch happens in line 1022 copy_from_user(buf, p, buf_len)

4. Given that `p` can be fully controlled in userspace, an attacker can
race condition to override the header part of `p`, say,
`((struct nd_cmd_pkg *)p)->nd_reserved2` to arbitrary value
(say nine 0xFFFFFFFF for `nd_reserved2`) after the first fetch but before the
second fetch. The changed value will be copied to `buf`.

5. There is no checks on the second fetches until the use of it in
line 1034: nd_cmd_clear_to_send(nvdimm_bus, nvdimm, cmd, buf) and
line 1038: nd_desc->ndctl(nd_desc, nvdimm, cmd, buf, buf_len, &cmd_rc)
which means that the assumed relation, `p->nd_reserved2` are all zeroes might
not hold after the second fetch. And once the control goes to these functions
we lose the context to assert the assumed relation.

6. Based on my manual analysis, `p->nd_reserved2` is not used in function
`nd_cmd_clear_to_send` and potential implementations of `nd_desc->ndctl`
so there is no working exploit against it right now. However, this could
easily turns to an exploitable one if careless developers start to use
`p->nd_reserved2` later and assume that they are all zeroes.

Move the validation of the nd_reserved2 field to the ->ndctl()
implementation where it has a stable buffer to evaluate.

+* PWM vibrator device tree bindings
+
+Registers a PWM device as vibrator. It is expected, that the vibrator's
+strength increases based on the duty cycle of the enable PWM channel
+(100% duty cycle meaning strongest vibration, 0% meaning no vibration).
+
+The binding supports an optional direction PWM channel, that can be
+driven at fixed duty cycle. If available this is can be used to increase
+the vibration effect of some devices.
+
+Required properties:
+- compatible: should contain "pwm-vibrator"
+- pwm-names: Should contain "enable" and optionally "direction"
+- pwms: Should contain a PWM handle for each entry in pwm-names
+
+Optional properties:

Subject: MIPS: lantiq: Convert the fpi bus driver to a platform_driver

Instead of hacking the configuration of the FPI bus into the arch code
add an own bus driver for this internal bus. The FPI bus is the main
bus of the SoC. This bus driver makes sure the bus is configured
correctly before the child drivers are getting initialized. This driver
will probably also be used on different SoCs later.

+Lantiq XWAY SoC FPI BUS binding
+============================
+
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible			: Should be one of
+					"lantiq,xrx200-fpi"
+- reg				: The address and length of the XBAR
+				  configuration register.
+				  Address and length of the FPI bus itself.
+- lantiq,rcu			: A phandle to the RCU syscon
+- lantiq,offset-endianness	: Offset of the endianness configuration
+				  register
+
+-------------------------------------------------------------------------------
+Example for the FPI on the xrx200 SoCs:
+	fpi@10000000 {
+		compatible = "lantiq,xrx200-fpi";
+		ranges = <0x0 0x10000000 0xf000000>;
+		reg =	<0x1f400000 0x1000>,
+			<0x10000000 0xf000000>;
+		lantiq,rcu = <&rcu0>;
+		lantiq,offset-endianness = <0x4c>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+
+		gptu@e100a00 {
+			......

From 79797b6fadf4d2b6ea639406e08c8ce1f259f6ae Mon Sep 17 00:00:00 2001
From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

Subject: reset: Add a reset controller driver for the Lantiq XWAY based SoCs

The reset controllers (on xRX200 and newer SoCs have two of them) are
provided by the RCU module. This was initially implemented as a simple
reset controller. However, the RCU module provides more functionality
(ethernet GPHYs, USB PHY, etc.), which makes it a MFD device.
The old reset controller driver implementation from
arch/mips/lantiq/xway/reset.c did not honor this fact.

For some devices the request and the status bits are different.

+Lantiq XWAY SoC RCU reset controller binding
+============================================
+
+This binding describes a reset-controller found on the RCU module on Lantiq
+XWAY SoCs.
+
+This node has to be a sub node of the Lantiq RCU block.
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible		: Should be one of
+				"lantiq,danube-reset"
+				"lantiq,xrx200-reset"
+- reg			: Defines the following sets of registers in the parent
+			  syscon device
+			- Offset of the reset set register
+			- Offset of the reset status register
+- #reset-cells		: Specifies the number of cells needed to encode the
+			  reset line, should be 2.
+			  The first cell takes the reset set bit and the
+			  second cell takes the status bit.
+
+-------------------------------------------------------------------------------
+Example for the reset-controllers on the xRX200 SoCs:
+	reset0: reset-controller@10 {
+		compatible = "lantiq,xrx200-reset";
+		reg <0x10 0x04>, <0x14 0x04>;
+
+		#reset-cells = <2>;
+	};

Subject: MIPS: lantiq: Add a GPHY driver which uses the RCU syscon-mfd

Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of
GE and FE GPHYs is now possible).
The new implementation is based on the RCU syscon-mfd and uses the
reeset_controller framework instead of raw RCU register reads/writes.

Subject: phy: Add an USB PHY driver for the Lantiq SoCs using the RCU module

This driver starts the DWC2 core(s) built into the XWAY SoCs and provides
the PHY interfaces for each core. The phy instances can be passed to the
dwc2 driver, which already supports the generic phy interface.

+Lantiq XWAY SoC RCU USB 1.1/2.0 PHY binding
+===========================================
+
+This binding describes the USB PHY hardware provided by the RCU module on the
+Lantiq XWAY SoCs.
+
+This node has to be a sub node of the Lantiq RCU block.
+
+-------------------------------------------------------------------------------
+Required properties (controller (parent) node):
+- compatible	: Should be one of
+			"lantiq,ase-usb2-phy"
+			"lantiq,danube-usb2-phy"
+			"lantiq,xrx100-usb2-phy"
+			"lantiq,xrx200-usb2-phy"
+			"lantiq,xrx300-usb2-phy"
+- reg		: Defines the following sets of registers in the parent
+		  syscon device
+			- Offset of the USB PHY configuration register
+			- Offset of the USB Analog configuration
+			  register (only for xrx200 and xrx200)
+- clocks	: References to the (PMU) "phy" clk gate.
+- clock-names	: Must be "phy"
+- resets	: References to the RCU USB configuration reset bits.
+- reset-names	: Must be one of the following:
+			"phy" (optional)
+			"ctrl" (shared)
+
+-------------------------------------------------------------------------------
+Example for the USB PHYs on an xRX200 SoC:
+	usb_phy0: usb2-phy@18 {
+		compatible = "lantiq,xrx200-usb2-phy";
+		reg = <0x18 4>, <0x38 4>;
+
+		clocks = <&pmu PMU_GATE_USB0_PHY>;
+		clock-names = "phy";
+		resets = <&reset1 4 4>, <&reset0 4 4>;
+		reset-names = "phy", "ctrl";
+		#phy-cells = <0>;
+	};

Subject: ashmem: switch to ->read_iter

And use the proper VFS helper for using the backing file.

Also make sure we hold ashmem_lock while updating f_pos to make sure that
it's not racy.

Subject: fs: fix kernel_read prototype

Use proper ssize_t and size_t types for the return value and count
argument, move the offset last and make it an in/out argument like
all other read/write helpers, and make the buf argument a void pointer
to get rid of lots of casts in the callers.

Subject: fs: fix kernel_write prototype

Make the position an in/out argument like all the other read/write
helpers and and make the buf argument a void pointer.

Subject: serial2002: switch serial2002_tty_write to kernel_{read/write}

Instead of playing games with the address limit.  This also gains
us proper usage of the write counter, time stamp updates and kvec
validation.

Subject: dmaengine: sun6i: make gate bit in sun8i's DMA engines a common quirk

Originally we enable a special gate bit when the compatible indicates
A23/33.

But according to BSP sources and user manuals, more SoCs will need this
gate bit.

So make it a common quirk configured in the config struct.

Subject: mfd: twl-core: Improve the documentation

Saying it "returns the result" seems tautological.  The read function
does not return num_bytes on success, it returns zero on success.  I
noticed this discrepancy because some of the callers were checking for
>= 0.

It is possible that under heavy system load, the counter in the completion
struct, used for waiting for end of AD conversion, gets incremented twice.
To make sure the driver recovers from this situation, the completion struct
should be reinitialized.

Subject: mfd: max8925-i2c: Drop unnecessary static

Drop static on a local variable, when the variable is initialized before
any use, on every possible execution path through the function.  The static
has no benefit, and dropping it reduces the code size.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@bad exists@
position p;
identifier x;

static T x@p;

type T;
position p != bad.p;

-static
 T x@p;
 ... when != x
     when strict
?x = e;
// </smpl>

The change in code size is indicates by the following output from the size
command.

Hi6421v530 and Hi6421 are PMIC chips from the same vendor, HiSilicon,
but at different revisions. They share the same memory-mapped I/O
design. They differ in integrated devices, such as regulator details,
LDO voltage points.

Subject: mfd: Add ROHM BD9571MWV-M MFD PMIC driver

Add the MFD part of the ROHM BD9571MWV-M PMIC driver and MAINTAINERS
entry. The MFD part only specifies the regmap bits for the PMIC and
binds the subdevs together.

Subject: mfd: axp20x: Add support for AXP813 PMIC

The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC.
It has the same range of functions as other X-Powers PMICs, such as
DC-DC buck converter and linear regulator outputs, AC-IN and VBUS
power supplies, power button trigger, GPIOs, ADCs, and a battery
charger.

Note that the IRQ table given in the datasheet is incorrect: in IRQ
enable/status registers 1, there are separate IRQs for ACIN and VBUS,
instead of bits [7:5] being the same as bits [4:2]. So it shares the
same IRQs as the AXP803, rather than the AXP288.

This patch adds basic mfd support for it, with only the power button
enabled.

Subject: mfd: axp20x: Use correct platform device ID for many PEK

According to their datasheets, the AXP221, AXP223, AXP288, AXP803,
AXP809 and AXP813 PEK have different values for startup time bits from
the AXP20X, let's use the platform device id with the correct values.

Subject: mfd: syscon: atmel-smc: Add helper to retrieve register layout

For HSMC controller, the register layout depends on the device i.e. the
offset of setup, pulse, cycle, mode and timings registers is not the
same. An helper is added to provide the correct register layout.

SMC regs manipulation")

Subject: mfd: lpc_ich: Do not touch SPI-NOR write protection bit on
 Haswell/Broadwell
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At least on Lenovo Thinkpad Yoga, the BIOS seems to monitor the SPI-NOR
write protection bit and if it is flipped to read/write it assumes the
BIOS configuration was changed on next reboot. It then, for unknown
reasons, resets the BIOS settings back to default.

We can prevent this by just leaving the write protection bit intact and
let the SPI-NOR driver know whether the device is writable or not. In
case of this particular Lenovo the SPI-NOR flash will be exposed as
read-only.

Subject: mfd: Add support for TPS68470 device

The TPS68470 device is an advanced power management
unit that powers a Compact Camera Module (CCM),
generates clocks for image sensors, drives a dual
LED for Flash and incorporates two LED drivers for
general purpose indicators.

This patch adds support for TPS68470 mfd device.

The PMIC provides ACPI OpRegions which must be available for other

Somehow its Kconfig option ended up being a tristate though, this fixes

Subject: mfd: intel-lpss: Put I2C and SPI controllers into reset state on
 suspend

Commit 274e43edcda6f ("mfd: intel-lpss: Do not put device in reset
state on suspend") changed the behavior on suspend by not putting LPSS
controllers into reset. This was done because S3/S0ix fail if UART
device is put into reset and no_console_suspend flag is enabled.

Because of the above change, I2C controller gets into a bad state if
it observes that the I2C lines are pulled low when power to I2C device
is cut off during suspend (generally, I2C lines are pulled to power
rail of the I2C device in order to ensure that there is no leakage
because of the pulls when device is turned off). This results in the
controller timing out for all future I2C operations after resume. It
is primarily because of the following sequence of operations:

During suspend:
1. I2C controller is disabled, but it is not put into reset.
2. Power to I2C device is cut off.
3. #2 results in the I2C lines being pulled low.

==> At this point the I2C controller gets into a bad state

On resume:
1. Power to I2C device is enabled.
2. #2 results in the I2C lines being pulled high.
3. I2C controller is enabled.

However, even after enabling the I2C controller, all future I2C xfers
fail since the controller is in a bad state and does not attempt to
make any transactions and hence times out.

In order to ensure that the controller does not get into a bad state,
this change puts it into reset if the controller type is not
UART. With this change, the order of operations is:

During suspend:
1. I2C controller is disabled and put into reset.
2. Power to I2C device is cut off.
3. #2 results in the I2C lines being pulled low.

On resume:
1. Power to I2C device is enabled.
2. #2 results in the I2C lines being pulled high.
3. I2C controller is enabled and taken out of reset.

gcc-8 notices that the register number calculation is wrong

This addresses it by always using a 32-bit offset number for
the register. This is apparently an old problem that previous
compilers did not find.

Subject: mfd: intel_soc_pmic: Export separate mfd-cell configs for BYT and CHT

Both Bay and Cherry Trail devices may be used together with a Crystal Cove
PMIC. Each platform has its own variant of the PMIC, which both use the
same ACPI HID, but they are not 100% compatible.

Looking at the android x86 kernel sources where most of the Crystal Cove
code comes from, it talks about "Valley View", "Bay Trail" and / or BYT
without ever mentioning Cherry Trail, with the exception of the regulator
driver. The Asus Zenfone-2 kernel code has 2 regulator drivers, one
for Crystal Cove and one for what it calls Crystal Cove Plus. The
Crystal Cove Plus regulator driver is the only one to mention Cherry
Trail and that driver uses different register addresses then the
normal (Bay Trail) Crystal Cove regulator driver, showing that at
least the regulator register addresses are different.

The GPIO code should work on both, and the PWM code is known to work on
both and is necessary for backlight control on some Cherry Trail devices.

Testing has shown that the ACPI OpRegion code otoh is causing problems
on Cherry Trail devices, which is not surprising as it deals with the
regulators and those have different register addresses on CHT.

Specifically the ACPI OpRegion code causes the external microsd slot on
a Dell Venue 8 5855 (Cherry Trail version) to not work and the eMMC to
become unreliable and throw lots of errors.

This commit replaces the single mfd_cell array currently used for Crystal
Cove with 2 separate arrays, one for the Bay Trail variant and one for
the Cherry Trail variant, note that the Cherry Trail version of the array
only contains gpio and pwm cells. The PMIC OpRegion cell is deliberately
not included and drivers for the other cells in the Bay Trail cell array
were never upstreamed.

This commits makes the intel_soc_pmic_core code check the _HRV of the

intel_soc_pmic_config_cht_crc based on this.

This fixes the Bay Trail specific ACPI OpRegion code causing problems
on Cherry Trail devices. Specifically this was causing the external

and the eMMC to become unreliable and throw lots of errors.

From 042fa8c7c04dd43b21be3ec5104681574a4f8f8c Mon Sep 17 00:00:00 2001
From: Alexandre Belloni <alexandre.belloni@free-electrons.com>

Subject: rtc: ds1307: remove regs member

ds1307->regs is never used before being read or initialized locally. There
is no point in keeping a copy in memory.

Also limit the size of the read buffer to what is really used, rename buf
to regs for consistency and use sizeof() where possible.

Subject: mac80211_hwsim: Use proper TX power

In struct ieee80211_tx_info, control.vif pointer and rate_driver_data[0]
falls on the same place, depending on the union usage.
During the whole TX process, the union is referred to as a control struct,
which holds the vif that is later used in the tx flow, especially in order
to derive the used tx power.
Referring direcly to rate_driver_data[0] and assigning a value to it,
overwrites the vif pointer, hence making all later references irrelevant.
Moreover, rate_driver_data[0] isn't used later in the flow in order to
retrieve the channel that it is pointing to.

Subject: dma-coherent: fix dma_declare_coherent_memory() logic error

A recent change interprets the return code of dma_init_coherent_memory
as an error value, but it is instead a boolean, where 'true' indicates
success. This leads causes the caller to always do the wrong thing,
and also triggers a compile-time warning about it:

drivers/base/dma-coherent.c: In function 'dma_declare_coherent_memory':
drivers/base/dma-coherent.c:99:15: error: 'mem' may be used uninitialized in this function [-Werror=maybe-uninitialized]

I ended up changing the code a little more, to give use the usual
error handling, as this seemed the best way to fix up the warning
and make the code look reasonable at the same time.

A patch I wrote myself several years ago removed SCSI target support
from the code under drivers/scsi. That patch removed the code that sets
uspace_req_q to a non-NULL value. Hence also remove the code that
depends on uspace_req_q != NULL.

Subject: PCI: iproc: Add 500ms delay during device shutdown

During soft reset (e.g., "reboot" from Linux) on some iProc-based SOCs, the
LCPLL clock and PERST both go off simultaneously.  This seems in accordance
with the PCIe Card Electromechanical spec, r2.0, sec 2.2.3, which says the
clock goes inactive after PERST# goes active, but doesn't specify how long
the clock should be valid after PERST#.

However, we have observed that with the iProc Stingray, some Intel NVMe
endpoints, e.g., the P3700 400GB series, are not detected correctly upon
the next boot sequence unless the clock remains valid for some time after
PERST# is asserted.

Delay 500ms after asserting PERST# before performing a reboot.  The 500ms
is experimentally determined.

PCI_EXP_CAP is an iProc-specific value, so rename it to IPROC_PCI_EXP_CAP
to make it obvious that it's not related to the generic values like
PCI_EXP_RTCTL, etc.  No functional change intended.

Subject: md/raid5: fix a race condition in stripe batch

We have a race condition in below scenario, say have 3 continuous stripes, sh1,
sh2 and sh3, sh1 is the stripe_head of sh2 and sh3:

CPU1				CPU2				CPU3
handle_stripe(sh3)
				stripe_add_to_batch_list(sh3)
				-> lock(sh2, sh3)
				-> lock batch_lock(sh1)
				-> add sh3 to batch_list of sh1
				-> unlock batch_lock(sh1)
								clear_batch_ready(sh1)
								-> lock(sh1) and batch_lock(sh1)
								-> clear STRIPE_BATCH_READY for all stripes in batch_list
								-> unlock(sh1) and batch_lock(sh1)
->clear_batch_ready(sh3)
-->test_and_clear_bit(STRIPE_BATCH_READY, sh3)
--->return 0 as sh->batch == NULL
				-> sh3->batch_head = sh1
				-> unlock (sh2, sh3)

In CPU1, handle_stripe will continue handle sh3 even it's in batch stripe list
of sh1. By moving sh3->batch_head assignment in to batch_lock, we make it
impossible to clear STRIPE_BATCH_READY before batch_head is set.

Thanks Stephane for helping debug this tricky issue.

The switch supports 8 egress queues per port, so indicate that such that
net/dsa/slave.c::dsa_slave_create can allocate the right number of TX queues.
While at it use SF2_NUM_EGRESS_QUEUE as a define for the number of queues we
support.

configure it correclty in order for the Broadcom tag ingress (CPU ->
switch) queue selection to work correctly since there is a 1:1 mapping
between switch egress queues and ingress queues.

Subject: rdma core: Add rdma_rw_mr_payload()

The amount of payload per MR depends on device capabilities and
the memory registration mode in use. The new rdma_rw API hides both,
making it difficult for ULPs to determine how large their transport
send queues need to be.

Expose the MR payload information via a new API.

Subject: gianfar: Fix Tx flow control deactivation

The wrong register is checked for the Tx flow control bit,
it should have been maccfg1 not maccfg2.
This went unnoticed for so long probably because the impact is
hardly visible, not to mention the tangled code from adjust_link().
First, link flow control (i.e. handling of Rx/Tx link level pause frames)
is disabled by default (needs to be enabled via 'ethtool -A').
Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few
old boards), which results in Tx flow control remaining always on
once activated.

This code is no longer used, the logging function was changed by commit

It was previously showing information about the type of the IRQ, if it's
polled, ignored or a normal interrupt. As we don't want information loss,
I have moved this code to phy_attached_print().

Subject: net: mdio-mux: add mdio_mux parameter to mdio_mux_init()

mdio_mux_init() use the parameter dev for two distinct thing:
1) Have a device for all devm_ functions
2) Get device_node from it

Since it is two distinct purpose, this patch add a parameter mdio_mux
that is linked to task 2.

This will also permit to register an of_node mdio-mux that lacks a direct
owning device.
For example a mdio-mux which is a subnode of a real device.

Subject: vhost_net: correctly check tx avail during rx busy polling

We check tx avail through vhost_enable_notify() in the past which is
wrong since it only checks whether or not guest has filled more
available buffer since last avail idx synchronization which was just
done by vhost_vq_avail_empty() before. What we really want is checking
pending buffers in the avail ring. Fix this by calling
vhost_vq_avail_empty() instead.

This issue could be noticed by doing netperf TCP_RR benchmark as
client from guest (but not host). With this fix, TCP_RR from guest to
localhost restores from 1375.91 trans per sec to 55235.28 trans per
sec on my laptop (Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz).

Subject: i40e: avoid NVM acquire deadlock during NVM update

X722 devices use the AdminQ to access the NVM, and this requires taking
the AdminQ lock. Because of this, we lock the AdminQ during
i40e_read_nvm(), which is also called in places where the lock is
already held, such as the firmware update path which wants to lock once
and then unlock when finished after performing several tasks.

Although this should have only affected X722 devices, commit
96a39aed25e6 ("i40e: Acquire NVM lock before reads on all devices",
2016-12-02) added locking for all NVM reads, regardless of device
family.

This resulted in us accidentally causing NVM acquire timeouts on all
devices, causing failed firmware updates which left the eeprom in
a corrupt state.

Create unsafe non-locked variants of i40e_read_nvm_word and
i40e_read_nvm_buffer, __i40e_read_nvm_word and __i40e_read_nvm_buffer
respectively. These variants will not take the NVM lock and are expected
to only be called in places where the NVM lock is already held if
needed.

Since the only caller of i40e_read_nvm_buffer() was in such a path,
remove it entirely in favor of the unsafe version. If necessary we can
always add it back in the future.

Additionally, we now need to hold the NVM lock in i40e_validate_checksum
because the call to i40e_calc_nvm_checksum now assumes that the NVM lock
is held. We can further move the call to read I40E_SR_SW_CHECKSUM_WORD
up a bit so that we do not need to acquire the NVM lock twice.

This should resolve firmware updates and also fix potential raise that
could have caused the driver to report an invalid NVM checksum upon
driver load.

Subject: md/raid5: preserve STRIPE_ON_UNPLUG_LIST in break_stripe_batch_list

In release_stripe_plug(), if a stripe_head has its STRIPE_ON_UNPLUG_LIST
set, it indicates that this stripe_head is already in the raid5_plug_cb
list and release_stripe() would be called instead to drop a reference
count. Otherwise, the STRIPE_ON_UNPLUG_LIST bit would be set for this
stripe_head and it will get queued into the raid5_plug_cb list.

Since break_stripe_batch_list() did not preserve STRIPE_ON_UNPLUG_LIST,
A stripe could be re-added to plug list while it is still on that list
in the following situation. If stripe_head A is added to another
stripe_head B's batch list, in this case A will have its
batch_head != NULL and be added into the plug list. After that,
stripe_head B gets handled and called break_stripe_batch_list() to
reset all the batched stripe_head(including A which is still on
the plug list)'s state and reset their batch_head to NULL.
Before the plug list gets processed, if there is another write request
comes in and get stripe_head A, A will have its batch_head == NULL
(cleared by calling break_stripe_batch_list() on B) and be added to
plug list once again.

Subject: s390/zcrypt: externalize test AP queue

Under certain specified conditions, the Test AP Queue (TAPQ)
subfunction of the Process Adjunct Processor Queue (PQAP) instruction
will be intercepted by a guest VM. The guest VM must have a means for
executing the intercepted instruction.

The vfio_ap driver will provide an interface to execute the
PQAP(TAPQ) instruction subfunction on behalf of a guest VM.
The code for executing the AP instructions currently resides in the
AP bus. This patch refactors the AP bus code to externalize access
to the PQAP(TAPQ) instruction subfunction to make it available to
the vfio_ap driver.

Subject: s390/zcrypt: externalize AP config info query

KVM has a need to fetch the crypto configuration information
as it is returned by the PQAP(QCI) instruction. This patch
introduces a new API ap_query_configuration() which provides
this info in a handy way for the caller.

Subject: bcache: fix sequential large write IO bypass
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sequential write IOs were tested with bs=1M by FIO in writeback cache
mode, these IOs were expected to be bypassed, but actually they did not.
We debug the code, and find in check_should_bypass():
    if (!congested &&
        mode == CACHE_MODE_WRITEBACK &&
        op_is_write(bio_op(bio)) &&
        (bio-＞bi_opf & REQ_SYNC))
        goto rescale
that means, If in writeback mode, a write IO with REQ_SYNC flag will not
be bypassed though it is a sequential large IO, It's not a correct thing
to do actually, so this patch remove these codes.

I try to execute the following command to trigger gc thread:

But it does not work, I debug the code in gc_should_run(), It works only
if in invalidating or sectors_to_gc < 0. So set sectors_to_gc to -1 to
meet the condition when we trigger gc by manual command.

Subject: bcache: correct cache_dirty_target in __update_writeback_rate()

__update_write_rate() uses a Proportion-Differentiation Controller
algorithm to control writeback rate. A dirty target number is used in
this PD controller to control writeback rate. A larger target number
will make the writeback rate smaller, on the versus, a smaller target
number will make the writeback rate larger.

bcache uses the following steps to calculate the target number,
1) cache_sectors = all-buckets-of-cache-set * buckets-size
2) cache_dirty_target = cache_sectors * cached-device-writeback_percent
3) target = cache_dirty_target *
(sectors-of-cached-device/sectors-of-all-cached-devices-of-this-cache-set)

The calculation at step 1) for cache_sectors is incorrect, which does
not consider dirty blocks occupied by flash only volume.

A flash only volume can be took as a bcache device without cached
device. All data sectors allocated for it are persistent on cache device
and marked dirty, they are not touched by bcache writeback and garbage
collection code. So data blocks of flash only volume should be ignore
when calculating cache_sectors of cache set.

Current code does not subtract dirty sectors of flash only volume, which
results a larger target number from the above 3 steps. And in sequence
the cache device's writeback rate is smaller then a correct value,
writeback speed is slower on all cached devices.

This patch fixes the incorrect slower writeback rate by subtracting
dirty sectors of flash only volumes in __update_writeback_rate().

Subject: bcache: Correct return value for sysfs attach errors

If you encounter any errors in bch_cached_dev_attach it will return
a negative error code.  The variable 'v' which stores the result is
unsigned, thus user space sees a very large value returned for bytes
written which can cause incorrect user space behavior.  Utilize 1
signed variable to use throughout the function to preserve error return
capability.

Subject: bcache: increase the number of open buckets

In currently, we only alloc 6 open buckets for each cache set,
but in usually, we always attach about 10 or so backend devices for
each cache set, and the each bcache device are always accessed by
about 10 or so threads in top application layer. So 6 open buckets
are too few, It has led to that each of the same thread write data
to different buckets, which would cause low efficiency write-back,
and also cause buckets inefficient, and would be Very easy to run
out of.

I add debug message in bch_open_buckets_alloc() to print alloc bucket
info, and test with ten bcache devices with a cache set, and each
bcache device is accessed by ten threads.

From the debug message, we can see that, after the modification, One
bucket is more likely to assign to the same thread, and the data from
the same thread are more likely to write the same bucket. Usually the
same thread always write/read the same backend device, so it is good
for write-back and also promote the usage efficiency of buckets.

In olden times, closure_return() used to have a hidden return built in.
We removed the hidden return but forgot to add a new return here.  If
"c" were NULL we would oops on the next line, but fortunately "c" is
never NULL.  Let's just remove the if statement.

Subject: bcache: fix bch_hprint crash and improve output

Most importantly, solve a crash where %llu was used to format signed
numbers.  This would cause a buffer overflow when reading sysfs
writeback_rate_debug, as only 20 bytes were allocated for this and
%llu writes 20 characters plus a null.

Always use the units mechanism rather than having different output
paths for simplicity.

Also, correct problems with display output where 1.10 was a larger
number than 1.09, by multiplying by 10 and then dividing by 1024 instead
of dividing by 100.  (Remainders of >= 1000 would print as .10).

Minor changes: Always display the decimal point instead of trying to
omit it based on number of digits shown.  Decide what units to use
based on 1000 as a threshold, not 1024 (in other words, always print
at most 3 digits before the decimal point).

Commit 6c6b6f28b333 ("loop: set physical block size to PAGE_SIZE")
caused mkfs.xfs to barf on ppc64 [1]. Always using PAGE_SIZE as the
physical block size still makes the most sense semantically, but let's
just lie and always set it to the same value as the logical block size
(same goes for io_min). In the future we might want to at least bump up
io_min to PAGE_SIZE but I'm sick of these stupid changes so let's play
it safe.

Subject: drm/i915: Re-enable GTT following a device reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ville Syrjälä spotted that PGETBL_CTL was losing its enable bit upon a
reset. That was causing the display to show garbage on his 945gm. On my
i915gm the effect was far more severe; re-enabling the display following
the reset without PGETBL_CTL being enabled lead to an immediate hard
hang.

We do have a routine to re-enable PGETBL_CTL which is applicable to
gen2-4, although on gen4 it is documented that a graphics reset doesn't
alter the register (no such wording is given for gen3) and should be safe
to call to punch back in the enable bit. However, that leaves the question
of whether we need to completely re-initialise the register and the
rest of the GSM. For g33/pnv/gen4+, where we do have a configurable
page table, its contents do seem to be kept, and so we should be able to
recover without having to reinitialise the GTT from scratch (as prior to
g33, that register is configured by the BIOS and we leave alone except
for the enable bit).

This appears to have been broken by commit 5fbd0418eef2 ("drm/i915:
Re-enable GGTT earlier during resume on pre-gen6 platforms"), which
moved the intel_enable_gtt() from i915_gem_init_hw() (also used by
reset) to add it earlier during hw init and resume, missing the reset
path.

v2: Find the culprit, rearrange ggtt_enable to be before gem_init_hw to
match init/resume

Subject: drm/i915: wire up shrinkctl->nr_scanned

shrink_slab() allows us to report back the number of objects we
successfully scanned (out of the target shrinkctl->nr_to_scan).  As
report the number of pages owned by each GEM object as a separate item
to the shrinker, we cannot precisely control the number of shrinker
objects we scan on each pass; and indeed may free more than requested.
If we fail to tell the shrinker about the number of objects we process,
it will continue to hold a grudge against us as any objects left
unscanned are added to the next reclaim -- and so we will keep on
"unfairly" shrinking our own slab in comparison to other slabs.

Subject: mm, memory_hotplug: display allowed zones in the preferred ordering

Prior to commit f1dd2cd13c4b ("mm, memory_hotplug: do not associate
hotadded memory to zones until online") we used to allow to change the
valid zone types of a memory block if it is adjacent to a different zone
type.

This fact was reflected in memoryNN/valid_zones by the ordering of
printed zones.  The first one was default (echo online > memoryNN/state)
and the other one could be onlined explicitly by online_{movable,kernel}.

This behavior was removed by the said patch and as such the ordering was
not all that important.  In most cases a kernel zone would be default
anyway.  The only exception is movable_node handled by "mm,
memory_hotplug: support movable_node for hotpluggable nodes".

Let's reintroduce this behavior again because later patch will remove
the zone overlap restriction and so user will be allowed to online
kernel resp.  movable block regardless of its placement.  Original
behavior will then become significant again because it would be
non-trivial for users to see what is the default zone to online into.

Implementation is really simple.  Pull out zone selection out of
move_pfn_range into zone_for_pfn_range helper and use it in
show_valid_zones to display the zone for default onlining and then both
kernel and movable if they are allowed.  Default online zone is not
duplicated.

From c6f03e2903c9ecd8fd709a5b3fa8cf0a8ae0b3da Mon Sep 17 00:00:00 2001

Subject: mm, memory_hotplug: remove zone restrictions

Historically we have enforced that any kernel zone (e.g ZONE_NORMAL) has
to precede the Movable zone in the physical memory range.  The purpose
of the movable zone is, however, not bound to any physical memory
restriction.  It merely defines a class of migrateable and reclaimable
memory.

There are users (e.g.  CMA) who might want to reserve specific physical
memory ranges for their own purpose.  Moreover our pfn walkers have to
be prepared for zones overlapping in the physical range already because
we do support interleaving NUMA nodes and therefore zones can interleave
as well.  This means we can allow each memory block to be associated
with a different zone.

Loosen the current onlining semantic and allow explicit onlining type on
any memblock.  That means that online_{kernel,movable} will be allowed
regardless of the physical address of the memblock as long as it is
offline of course.  This might result in moveble zone overlapping with
other kernel zones.  Default onlining then becomes a bit tricky but
still sensible.  echo online > memoryXY/state will online the given
block to

	1) the default zone if the given range is outside of any zone
	2) the enclosing zone if such a zone doesn't interleave with
	   any other zone
        3) the default zone if more zones interleave for this range

where default zone is movable zone only if movable_node is enabled
otherwise it is a kernel zone.

Here is an example of the semantic with (movable_node is not present but
it work in an analogous way). We start with following memblocks, all of
them offline:

  memory34/valid_zones:Normal Movable
  memory35/valid_zones:Normal Movable
  memory36/valid_zones:Normal Movable
  memory37/valid_zones:Normal Movable
  memory38/valid_zones:Normal Movable
  memory39/valid_zones:Normal Movable
  memory40/valid_zones:Normal Movable
  memory41/valid_zones:Normal Movable

Now, we online block 34 in default mode and block 37 as movable

  root@test1:/sys/devices/system/node/node1# echo online > memory34/state
  root@test1:/sys/devices/system/node/node1# echo online_movable > memory37/state
  memory34/valid_zones:Normal
  memory35/valid_zones:Normal Movable
  memory36/valid_zones:Normal Movable
  memory37/valid_zones:Movable
  memory38/valid_zones:Normal Movable
  memory39/valid_zones:Normal Movable
  memory40/valid_zones:Normal Movable
  memory41/valid_zones:Normal Movable

As we can see all other blocks can still be onlined both into Normal and
Movable zones and the Normal is default because the Movable zone spans
only block37 now.

  root@test1:/sys/devices/system/node/node1# echo online_movable > memory41/state
  memory34/valid_zones:Normal
  memory35/valid_zones:Normal Movable
  memory36/valid_zones:Normal Movable
  memory37/valid_zones:Movable
  memory38/valid_zones:Movable Normal
  memory39/valid_zones:Movable Normal
  memory40/valid_zones:Movable Normal
  memory41/valid_zones:Movable

Now the default zone for blocks 37-41 has changed because movable zone
spans that range.

  root@test1:/sys/devices/system/node/node1# echo online_kernel > memory39/state
  memory34/valid_zones:Normal
  memory35/valid_zones:Normal Movable
  memory36/valid_zones:Normal Movable
  memory37/valid_zones:Movable
  memory38/valid_zones:Normal Movable
  memory39/valid_zones:Normal
  memory40/valid_zones:Movable Normal
  memory41/valid_zones:Movable

Note that the block 39 now belongs to the zone Normal and so block38
falls into Normal by default as well.

For completness

  root@test1:/sys/devices/system/node/node1# for i in memory[34]?
  do
	echo online > $i/state 2>/dev/null
  done

  memory34/valid_zones:Normal
  memory35/valid_zones:Normal
  memory36/valid_zones:Normal
  memory37/valid_zones:Movable
  memory38/valid_zones:Normal
  memory39/valid_zones:Normal
  memory40/valid_zones:Movable
  memory41/valid_zones:Movable

Implementation wise the change is quite straightforward.  We can get rid
of allow_online_pfn_range altogether.  online_pages allows only offline
nodes already.  The original default_zone_for_pfn will become
default_kernel_zone_for_pfn.  New default_zone_for_pfn implements the
above semantic.  zone_for_pfn_range is slightly reorganized to implement
kernel and movable online type explicitly and MMOP_ONLINE_KEEP becomes a
catch all default behavior.

Subject: zram: clean up duplicated codes in __zram_bvec_write

Patch series "writeback incompressible pages to storage", v1.

zRam is useful for memory saving with compressible pages but sometime,
workload can be changed and system has lots of incompressible pages
which is very harmful for zram.

This patch supports writeback feature of zram so admin can set up a
block device and with it, zram can save the memory via writing out the
incompressile pages once it found it's incompressible pages (1/4 comp
ratio) instead of keeping the page in memory.

[1-3] is just clean up and [4-8] is step by step feature enablement.
[4-8] is logically not bisectable(ie, logical unit separation)
although I tried to compiled out without breaking but I think it would
be better to review.

This patch (of 9):

__zram_bvec_write has some of duplicated logic for zram meta data
handling of same_page|compressed_page.  This patch aims to clean it up
without behavior change.

Subject: zram: inline zram_compress

zram_compress does several things, compress, entry alloc and check
limitation.  I did for just readbility but it hurts modulization.:(

So this patch removes zram_compress functions and inline it in
__zram_bvec_write for upcoming patches.

Subject: zram: rename zram_decompress_page to __zram_bvec_read

zram_decompress_page naming is not proper because it doesn't decompress
if page was dedup hit or stored with compression.

Use more abstract term and consistent with write path function
__zram_bvec_write.

Subject: zram: add interface to specif backing device

For writeback feature, user should set up backing device before the zram
working.

This patch enables the interface via /sys/block/zramX/backing_dev.

Currently, it supports block device only but it could be enhanced for
file as well.

Subject: zram: add free space management in backing device

With backing device, zram needs management of free space of backing
device.

This patch adds bitmap logic to manage free space which is very naive.
However, it would be simple enough as considering uncompressible pages's
frequenty in zram.

Subject: zram: identify asynchronous IO's return value

For upcoming asynchronous IO like writeback, zram_rw_page should be
aware of that whether requested IO was completed or submitted
successfully, otherwise error.

For the goal, zram_bvec_rw has three return values.

-errno: returns error number
     0: IO request is done synchronously
     1: IO request is issued successfully.

Subject: zram: write incompressible pages to backing device

This patch enables write IO to transfer data to backing device.  For
that, it implements write_to_bdev function which creates new bio and
chaining with parent bio to make the parent bio asynchrnous.

For rw_page which don't have parent bio, it submit owned bio and handle
IO completion by zram_page_end_io.

Also, this patch defines new flag ZRAM_WB to mark written page for later
read IO.

Subject: zram: read page from backing device

This patch enables read IO from backing device.  For the feature, it
implements two IO read functions to transfer data from backing storage.

One is asynchronous IO function and other is synchronous one.

A reason I need synchrnous IO is due to partial write which need to
complete read IO before the overwriting partial data.

We can make the partial IO's case asynchronous, too but at the moment, I
don't feel adding more complexity to support such rare use cases so want
to go with simple.

Subject: block, THP: make block_device_operations.rw_page support THP

The .rw_page in struct block_device_operations is used by the swap
subsystem to read/write the page contents from/into the corresponding
swap slot in the swap device.  To support the THP (Transparent Huge
Page) swap optimization, the .rw_page is enhanced to support to
read/write THP if possible.

In commit bcd37f4a0831 ("rtlwifi: btcoex: 23b 2ant: let bt transmit when
hw initialisation done"), there is an additional error when the module
parameter ant_sel is used to select the auxilary antenna. The error is
that the antenna selection is not checked when writing the antenna
selection register.

In commit 87d8a9f35202 ("rtlwifi: btcoex: call bind to setup btcoex"),
the code turns on a call to exhalbtc_bind_bt_coex_withadapter(). This
routine contains a bug that causes incorrect antenna selection for those
HP laptops with only one antenna and an incorrectly programmed EFUSE.
These boxes are the ones that need the ant_sel module parameter.

Subject: iwlwifi: mvm: only send LEDS_CMD when the FW supports it

The LEDS_CMD command is only supported in some newer FW versions
(e.g. iwlwifi-8000C-31.ucode), so we can't send it to older versions
(such as iwlwifi-8000C-27.ucode).

To fix this, check for a new bit in the FW capabilities TLV that tells
when the command is supported.

Note that the current version of -31.ucode in linux-firmware.git
(31.532993.0) does not have this capability bit set, so the LED won't
work, even though this version should support it.  But we will update
this firmware soon, so it won't be a problem anymore.

Convert all WARN* style messages to dev_WARN, and for errors in the IO

and replace them with the above - no need to crash the machine in case
of an unaligned IO.

Subject: bcache: initialize dirty stripes in flash_dev_run()

bcache uses a Proportion-Differentiation Controller algorithm to control
writeback rate to cached devices. In the PD controller algorithm, dirty
stripes of thin flash device should not be counted in, because flash only
volumes never write back dirty data.

Currently dirty stripe counter for thin flash device is not initialized
when the thin flash device starts. Which means the following calculation
in PD controller will reference an undefined dirty stripes number, and
all cached devices attached to the same cache set where the thin flash
device lies on may have an inaccurate writeback rate.

This patch calles bch_sectors_dirty_init() in flash_dev_run(), to
correctly initialize dirty stripe counter when the thin flash device
starts to run. This patch also does following parameter data type change,
 -void bch_sectors_dirty_init(struct cached_dev *dc);
 +void bch_sectors_dirty_init(struct bcache_device *);
to call this function conveniently in flash_dev_run().

Subject: isdn: isdnloop: fix logic error in isdnloop_sendbuf

gcc-7 found an ancient bug in the loop driver, leading to a condition that
is always false, meaning we ignore the contents of 'card->flags' here:

drivers/isdn/isdnloop/isdnloop.c:412:37: error: ?: using integer constants in boolean context, the expression will always evaluate to 'true' [-Werror=int-in-bool-context]

This changes the braces in the expression to ensure we actually
compare the flag bits, rather than comparing a constant. As Joe Perches
pointed out, an earlier patch of mine incorrectly assumed this was a
false-positive warning.

This is caused by:

  platform_device_register()
   -> platform_device_unregister(to_platform_device(dev))
	freeing struct device
   -> of_node_clear_flag(dev->of_node, ...)
	writing to the freed device

The issue is solved by increasing the reference count before calling
of_platform_device_destroy() so freeing the device is postponed after
the call.

Subject: RDMA/netlink: clean up message validity array initializer

The fix in the parent made me look at that function, and react to how
illogical and illegible the array initializer was.

Use named array indexes to make it clearer what is going on, and make
the initializer not depend silently on the exact index numbers.

[ The initializer now also shows an odd inconsistency in the naming:
  note the IWCM vs IWPM..   - Linus ]

Subject: mm: change the call sites of numa statistics items

Patch series "Separate NUMA statistics from zone statistics", v2.

Each page allocation updates a set of per-zone statistics with a call to
zone_statistics().  As discussed in 2017 MM summit, these are a
substantial source of overhead in the page allocator and are very rarely
consumed.  This significant overhead in cache bouncing caused by zone
counters (NUMA associated counters) update in parallel in multi-threaded
page allocation (pointed out by Dave Hansen).

A link to the MM summit slides:
  http://people.netfilter.org/hawk/presentations/MM-summit2017/MM-summit2017-JesperBrouer.pdf

To mitigate this overhead, this patchset separates NUMA statistics from
zone statistics framework, and update NUMA counter threshold to a fixed
size of MAX_U16 - 2, as a small threshold greatly increases the update
frequency of the global counter from local per cpu counter (suggested by
Ying Huang).  The rationality is that these statistics counters don't
need to be read often, unlike other VM counters, so it's not a problem
to use a large threshold and make readers more expensive.

With this patchset, we see 31.3% drop of CPU cycles(537-->369, see
below) for per single page allocation and reclaim on Jesper's
page_bench03 benchmark.  Meanwhile, this patchset keeps the same style
of virtual memory statistics with little end-user-visible effects (only
move the numa stats to show behind zone page stats, see the first patch
for details).

I did an experiment of single page allocation and reclaim concurrently
using Jesper's page_bench03 benchmark on a 2-Socket Broadwell-based
server (88 processors with 126G memory) with different size of threshold
of pcp counter.

Benchmark provided by Jesper D Brouer(increase loop times to 10000000):

This patch (of 3):

In this patch, NUMA statistics is separated from zone statistics
framework, all the call sites of NUMA stats are changed to use
numa-stats-specific functions, it does not have any functionality change
except that the number of NUMA stats is shown behind zone page stats
when users *read* the zone info.

Subject: linux/kernel.h: move DIV_ROUND_DOWN_ULL() macro

This macro is useful to avoid link error on 32-bit systems.

We have the same definition in two drivers, so move it to
include/linux/kernel.h

While we are here, refactor DIV_ROUND_UP_ULL() by using
DIV_ROUND_DOWN_ULL().

Subject: drivers/scsi/sym53c8xx_2/sym_hipd.c: convert to use memset32

memset32() can be used to initialise these three arrays.  Minor code
footprint reduction.

Subject: treewide: make "nr_cpu_ids" unsigned

First, number of CPUs can't be negative number.

Second, different signnnedness leads to suboptimal code in the following
cases:

1)
	kmalloc(nr_cpu_ids * sizeof(X));

"int" has to be sign extended to size_t.

2)
	while (loff_t *pos < nr_cpu_ids)

MOVSXD is 1 byte longed than the same MOV.

Other cases exist as well. Basically compiler is told that nr_cpu_ids
can't be negative which can't be deduced if it is "int".

Code savings on allyesconfig kernel: -3KB

Subject: lib/interval_tree: fast overlap detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allow interval trees to quickly check for overlaps to avoid unnecesary
tree lookups in interval_tree_iter_first().

As of this patch, all interval tree flavors will require using a
'rb_root_cached' such that we can have the leftmost node easily
available.  While most users will make use of this feature, those with
special functions (in addition to the generic insert, delete, search
calls) will avoid using the cached option as they can do funky things
with insertions -- for example, vma_interval_tree_insert_after().

Subject: net: phy: sfp: rename dt properties to match the binding

Make the Rx rate select control gpio property name match the documented
binding. This would make the addition of 'rate-select1-gpios' for SFP+
support more natural.

Also, make the MOD-DEF0 gpio property name match the documentation.

Subject: Revert "mdio_bus: Remove unneeded gpiod NULL check"

This reverts commit 95b80bf3db03c2bf572a357cf74b9a6aefef0a4a ("mdio_bus:
Remove unneeded gpiod NULL check"), this commit assumed that GPIOLIB
checks for NULL descriptors, so it's safe to drop them, but it is not
when CONFIG_GPIOLIB is disabled in the kernel. If we do call
gpiod_set_value_cansleep() on a GPIO descriptor we will issue warnings
coming from the inline stubs declared in include/linux/gpio/consumer.h.

Subject: watchdog: meson-wdt: add support for the watchdog on Meson8 and
 Meson8m2

The watchdog IP block on Meson8 and Meson8m2 is already supported by the
existing meson-wdt driver. Meson8 uses the same register bits as Meson6,
while the newer Meson8m2 SoC uses the same register bits as Meson8b.

Currently watchdog support on Meson8 SoC already works because
meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a
separate compatible for Meson8 makes this more explicit though.

Subject: watchdog: renesas_wdt: avoid (theoretical) type overflow

Because the smallest clock divider we can select is 1, 'clks_per_sec'
must be the same type as 'rate'.

Subject: watchdog: renesas_wdt: apply better precision

The error margin of the clks_per_second variable was too large and
caused offsets when used with clock frequencies which left a remainder
after applying the dividers. Now we always calculate directly using the
clock rate and the divider using some helper macros. That also means
that DIV_ROUND_UP moves from probe to the multiplication macro. In
probe, we don't need to ensure anymore that 'clks_per_sec' would go too
fast but rather ensure that the lower limit is really at least 1 to
certainly get a full cycle.

Subject: watchdog: qcom: Check for platform_get_resource() failure

platform_get_resource() may fail, so we should better check its
return value and propagate an error in case it fails.

This avoids a NULL pointer dereference a bit later in the code.

Subject: watchdog: da9063_wdt: Simplify by removing unneeded struct...

...da9063_watchdog, which contained nothing but struct watchdog_device and a
struct da9063 pointer.
Assign the struct da9063 pointer directly to the struct watchdog_device's
driver_data field instead of creating struct da9063_watchdog and assigning
it's address there.
Spares a pointer's size data memory and an indirection level in the callbacks.

Subject: drivers/watchdog: ASPEED reference dev tree properties for config

Reference the system device tree when configuring the watchdog
engines. If property 'aspeed,reset_type' is present then set
reset behavior based on the specified value.  This can be one of
three different mutually exclusive values
  * cpu - Reset CPU only on watchdog timeout
  * soc - Reset System on Chip
  * system - Full system reset

No reset can also be specified by indicating:
  * none - No reset, assumes another watchdog is responsible for
           this.

Add optional property 'aspeed,external-signal'. If present then
configure to generate external signal on watchdog timeout.

Subject: watchdog: renesas_wdt: consistently use RuntimePM for clock
 management

On Renesas R-Car archs, RuntimePM does all the clock handling. So, use
it consistently to enable/disable the clocks. Also make sure that clocks
are really enabled around clk_get_rate(). clk_summary looks proper now:

		clock	enable_cnt	prepare_cnt	rate ...

Subject: net: qualcomm: rmnet: Fix a double free

There is a typo here so we accidentally free "skb" instead of "skbn".
It leads to a double free and a leak.  After discussing with Subash,
it's better to just move the check before the allocation and avoid the
need to free.

Subject: Revert "firmware: add sanity check on shutdown/suspend"

This reverts commit 81f95076281fdd3bc382e004ba1bce8e82fccbce.

It causes random failures of firmware loading at resume time (well,
random for me, it seems to be more reliable for others) because the
firmware disabling is not actually synchronous with any particular
resume event, and at least the btusb driver that uses a workqueue to
load the firmware at resume seems to occasionally hit the "firmware
loading is disabled" logic because the firmware loader hasn't gotten the
resume event yet.

Some kind of sanity check for not trying to load firmware when it's not
possible might be a good thing, but this commit was not it.

Greg seems to have silently suffered the same issue, and pointed to the
likely culprit, and Gabriel C verified the revert fixed it for him too.

Subject: dm log writes: don't use all the cpu while waiting to log blocks

The check to see if the logging kthread needs to go to sleep is wrong,
it checks lc->pending_blocks, which will be non-0 if there are any
blocks that are pending, whether they are ready to be logged or not.
What we really want is to go to sleep until it's time to log blocks, so
change this check so we do actually go to sleep in between flushes.

Subject: dm log writes: fix >512b sectorsize support

512b sectors vs device's physical sectorsize was not maintained
consistently and as such the support for >512b sector devices has bugs.
The log metadata expects native sectorsize but 512b sectors were being
stored.  Also, device's sectorsize was assumed when assigning the
bi_sector for blocks that were being logged.

Fix this up by adding two helpers to convert between bio and dev
sectors, and use these in the appropriate places to fix the problem and
make it clear which units go where.  Doing so allows dm-log-writes use
with 4k devices.

Even though read operations fail, dm_integrity_map_continue() calls
integrity_metadata() to check integrity.  In this case, just complete
these.

This also makes it so read I/O errors do not generate integrity warnings
in the kernel log.

Subject: dm integrity: make blk_integrity_profile structure const

Make this structure const as it is only stored in the profile field of a
blk_integrity structure. This field is of type const, so make structure
as const.

Subject: dm integrity: use init_completion instead of
 COMPLETION_INITIALIZER_ONSTACK

The new lockdep support for completions causeed the stack usage
in dm-integrity to explode, in case of write_journal from 504 bytes
to 1120 (using arm gcc-7.1.1):

drivers/md/dm-integrity.c: In function 'write_journal':
drivers/md/dm-integrity.c:827:1: error: the frame size of 1120 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

The problem is that not only the size of 'struct completion' grows
significantly, but we end up having multiple copies of it on the stack
when we assign it from a local variable after the initial declaration.

COMPLETION_INITIALIZER_ONSTACK() is the right thing to use when we
want to declare and initialize a completion on the stack. However,
this driver doesn't do that and instead initializes the completion
just before it is used.

In this case, init_completion() does the same thing more efficiently,
and drops the stack usage for the function above down to 496 bytes.
While the other functions in this file are not bad enough to cause
a warning, they benefit equally from the change, so I do the change
across the entire file. In the one place where we reuse a completion,
I picked the cheaper reinit_completion() over init_completion().

Subject: dax: remove the pmem_dax_ops->flush abstraction

Commit abebfbe2f731 ("dm: add ->flush() dax operation support") is
buggy. A DM device may be composed of multiple underlying devices and
all of them need to be flushed. That commit just routes the flush
request to the first device and ignores the other devices.

It could be fixed by adding more complex logic to the device mapper. But
there is only one implementation of the method pmem_dax_ops->flush - that
is pmem_dax_flush() - and it calls arch_wb_cache_pmem(). Consequently, we
don't need the pmem_dax_ops->flush abstraction at all, we can call
arch_wb_cache_pmem() directly from dax_flush() because dax_dev->ops->flush
can't ever reach anything different from arch_wb_cache_pmem().

It should be also pointed out that for some uses of persistent memory it
is needed to flush only a very small amount of data (such as 1 cacheline),
and it would be overkill if we go through that device mapper machinery for
a single flushed cache line.

Fix this by removing the pmem_dax_ops->flush abstraction and call
arch_wb_cache_pmem() directly from dax_flush(). Also, remove the device
mapper code that forwards the flushes.

Subject: nvme: fix lightnvm check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

nvme_nvm_ns_supported assumes every device is a pci_dev, which leads to
reading an incorrect field, or possible even a dereference of unallocated
memory for fabrics controllers.

Fix this by introducing a quirk for lighnvm capable devices instead.

Subject: nvme-pci: fix host memory buffer allocation fallback

nvme_alloc_host_mem currently contains two loops that are interwinded,
and the outer retry loop turns out to be broken.  Fix this by untangling
the two.

Based on a report an initial patch from Akinobu Mita.

Subject: nvme-pci: use appropriate initial chunk size for HMB allocation

The initial chunk size for host memory buffer allocation is currently
PAGE_SIZE << MAX_ORDER.  MAX_ORDER order allocation is usually failed
without CONFIG_DMA_CMA.  So the HMB allocation is retried with chunk size
PAGE_SIZE << (MAX_ORDER - 1) in general, but there is no problem if the
retry allocation works correctly.

Subject: nvme-pci: propagate (some) errors from host memory buffer setup

We want to catch command execution errors when resetting the device, so
propagate errors from the Set Features when setting up the host memory
buffer.  We keep ignoring memory allocation failures, as the spec
clearly says that the controller must work without a host memory buffer.

Adds support for the new Host Memory Buffer Minimum Descriptor Entry Size
and Host Memory Maximum Descriptors Entries field that were added in
TP 4002 HMB Enhancements.  These allow the controller to advertise
limits for the usual number of segments in the host memory buffer, as
well as a minimum usable per-segment size.

Subject: hv_netvsc: fix deadlock on hotplug

When a virtual device is added dynamically (via host console), then
the vmbus sends an offer message for the primary channel. The processing
of this message for networking causes the network device to then
initialize the sub channels.

The problem is that setting up the sub channels needs to wait until
the subsequent subchannel offers have been processed. These offers
come in on the same ring buffer and work queue as where the primary
offer is being processed; leading to a deadlock.

This did not happen in older kernels, because the sub channel waiting
logic was broken (it wasn't really waiting).

The solution is to do the sub channel setup in its own work queue
context that is scheduled by the primary channel setup; and then
happens later.

Subject: Input: goodix - add support for capacitive home button

On some x86 tablets with a Goodix touchscreen, the Windows logo on the
front is a capacitive home button. Touching this button results in a touch
with bit 4 of the first byte set, while only the lower 4 bits (0-3) are
used to indicate the number of touches.

Report a KEY_LEFTMETA press when this happens.

Note that the hardware might support more than one button, in which
case the "id" byte of coor_data would identify the button in question.
This is not implemented as we don't have access to hardware with
multiple buttons.

Subject: Input: edt-ft5x06 - fix access to non-existing register

reg_addr->reg_report_rate is supposed to exist in M06, not M09.

The driver is written to skip avoids access to non-existing registers
when the register address is NO_REGISTER (0xff). But
reg_addr->reg_report_rate is initialized to 0x00 by devm_kzalloc() (in
edt_ft5x06_ts_probe()) and not changed thereafter. So the checks do
not work and an access to register 0x00 is done.

Fix by setting reg_addr->reg_report_rate to NO_REGISTER.

Also fix the only place where reg_report_rate is checked against zero
instead of NO_REGISTER.

Subject: Input: ucb1400_ts - fix suspend and resume handling

Instead of stopping the touchscreen we were starting it in suspend, and
disabling it in resume.

Subject: net: bonding: Fix transmit load balancing in balance-alb mode if
 specified by sysfs

Commit cbf5ecb30560 ("net: bonding: Fix transmit load balancing in
balance-alb mode") tried to fix transmit dynamic load balancing in
balance-alb mode, which wasn't working after commit 8b426dc54cf4
("bonding: remove hardcoded value").

It turned out that my previous patch only fixed the case when
balance-alb was specified as bonding module parameter, and not when
balance-alb mode was set using /sys/class/net/*/bonding/mode (the most
common usage).  In the latter case, tlb_dynamic_lb was set up according
to the default mode of the bonding interface, which happens to be
balance-rr.

This additional patch addresses this issue by setting up tlb_dynamic_lb
to 1 if "mode" is set to balance-alb through the sysfs interface.

I didn't add code to change tlb_balance_lb back to the default value for
other modes, because "mode" is usually set up only once during
initialization, and it's not worthwhile to change the static variable
bonding_defaults in bond_main.c to a global variable just for this
purpose.

Commit 8b426dc54cf4 also changes the value of tlb_dynamic_lb for
balance-tlb mode if it is set up using the sysfs interface.  I didn't
change that behavior, because the value of tlb_balance_lb can be changed
using the sysfs interface for balance-tlb, and I didn't like changing
the default value back and forth for balance-tlb.

As for balance-alb, /sys/class/net/*/bonding/tlb_balance_lb cannot be
written to.  However, I think balance-alb with tlb_dynamic_lb set to 0
is not an intended usage, so there is little use making it writable at
this moment.

The functions sprd_pmx_get_function_count, sprd_pmx_get_function_name
and sprd_pmx_get_function_groups are local to the source and do not
need to be in global scope, so make them static.

Cleans up sparse warnings:
"symbol 'sprd_pmx_get_function_count' was not declared. Should it be
static?"

devm_pinctrl_get() could fail with ERR_PTR(-ENOMEM) so I have added a

This patch moves the initialization of the mask field in the irq_startup
function. However some callbacks such as irq_set_type and irq_set_wake
could be called before irq_startup. For those functions the mask is
computed at each call which is not a issue as these functions are not
located in a hot path but are used sporadically for configuration.

Subject: pinctrl/amd: save pin registers over suspend/resume

The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is
unresponsive after suspend/resume. The following error appears during
resume:

  i2c_hid i2c-ELAN1300:00: failed to reset device.

The problem here is that i2c_hid does not notice the interrupt being
generated at this point, because the GPIO is no longer configured
for interrupts.

Fix this by saving pinctrl-amd pin registers during suspend and
restoring them at resume time.

Based on code from pinctrl-intel.

Subject: drm/amdgpu: revert "fix deadlock of reservation between cs and gpu
 reset v2"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit 10e709cb296c98424c03408d23e3addeddcd4088.

The patch doesn't work at all:
1. The CS can still be blocked because of amdgpu_ctx_add_fence().
2. The order of submission isn't correct any more.
3. We could end up using freed up memory because we now drop the
   ctx reference to early.

This needs to be fixed cleanly by doing the context handling after the BO
handling, but this is a larger task just avoid the obvious crashes for now.

Subject: mlxsw: spectrum: Prevent mirred-related crash on removal

When removing the offloading of mirred actions under
matchall classifiers, mlxsw would find the destination port
associated with the offloaded action and utilize it for undoing
the configuration.

Depending on the order by which ports are removed, it's possible that
the destination port would get removed before the source port.
In such a scenario, when actions would be flushed for the source port
mlxsw would perform an illegal dereference as the destination port is
no longer listed.

Since the only item necessary for undoing the configuration on the
destination side is the port-id and that in turn is already maintained
by mlxsw on the source-port, simply stop trying to access the
destination port and use the port-id directly instead.

Subject: net: bonding: fix tlb_dynamic_lb default value

Commit 8b426dc54cf4 ("bonding: remove hardcoded value") changed the
default value for tlb_dynamic_lb which lead to either broken ALB mode
(since tlb_dynamic_lb can be changed only in TLB) or setting TLB mode
with tlb_dynamic_lb equal to 0.
The first issue was recently fixed by setting tlb_dynamic_lb to 1 always
when switching to ALB mode, but the default value is still wrong and
we'll enter TLB mode with tlb_dynamic_lb equal to 0 if the mode is
changed via netlink or sysfs. In order to restore the previous behaviour
and default value simply remove the mode check around the default param
initialization for tlb_dynamic_lb which will always set it to 1 as
before.

Subject: be2net: fix TSO6/GSO issue causing TX-stall on Lancer/BEx

IPv6 TSO requests with extension hdrs are a problem to the
Lancer and BEx chips. Workaround is to disable TSO6 feature
for such packets.

Also in Lancer chips, MSS less than 256 was resulting in TX stall.
Fix this by disabling GSO when MSS less than 256.

Subject: ubi: pr_err() strings should end with newlines

The ubi_init() function has a few error paths that use the
pr_err() to output errors. These should have new lines on
them as pr_err() does not automatically do this.

This fixes issues where if multiple mtd fail to bind to
ubi the console output starts wrapping around.

Subject: nfp: wait for board state before talking to the NSP

Board state informs us which low-level initialization stages the card
has completed.  We should wait for the card to be fully initialized
before trying to communicate with it, not only before we configure
passing traffic.

Subject: nfp: wait for the NSP resource to appear on boot

The control process (NSP) may take some time to complete its
initialization.  This is not a problem on most servers, but
on very fast-booting machines it may not be ready for operation
when driver probes the device.  There is also a version of the
flash in the wild where NSP tries to train the links as part
of init.  To wait for NSP initialization we should make sure
its resource has already been added to the resource table.
NSP adds itself there as last step of init.

Subject: IB/mlx4: fix sprintf format warning

gcc-7 points out that a negative port_num value would overflow the
string buffer:

  drivers/infiniband/hw/mlx4/sysfs.c: In function 'mlx4_ib_device_register_sysfs':
  drivers/infiniband/hw/mlx4/sysfs.c:251:16: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=]
  drivers/infiniband/hw/mlx4/sysfs.c:251:2: note: 'sprintf' output between 2 and 11 bytes into a destination of size 10
  drivers/infiniband/hw/mlx4/sysfs.c:303:17: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=]
  drivers/infiniband/hw/mlx4/sysfs.c:303:3: note: 'sprintf' output between 2 and 11 bytes into a destination of size 10

While we should be able to assume that port_num is positive here, making
the buffer one byte longer has no downsides and avoids the warning.

Subject: mm: treewide: remove GFP_TEMPORARY allocation flag

GFP_TEMPORARY was introduced by commit e12ba74d8ff3 ("Group short-lived
and reclaimable kernel allocations") along with __GFP_RECLAIMABLE.  It's
primary motivation was to allow users to tell that an allocation is
short lived and so the allocator can try to place such allocations close
together and prevent long term fragmentation.  As much as this sounds
like a reasonable semantic it becomes much less clear when to use the
highlevel GFP_TEMPORARY allocation flag.  How long is temporary? Can the
context holding that memory sleep? Can it take locks? It seems there is
no good answer for those questions.

The current implementation of GFP_TEMPORARY is basically GFP_KERNEL |
__GFP_RECLAIMABLE which in itself is tricky because basically none of
the existing caller provide a way to reclaim the allocated memory.  So
this is rather misleading and hard to evaluate for any benefits.

I have checked some random users and none of them has added the flag
with a specific justification.  I suspect most of them just copied from
other existing users and others just thought it might be a good idea to
use without any measuring.  This suggests that GFP_TEMPORARY just
motivates for cargo cult usage without any reasoning.

I believe that our gfp flags are quite complex already and especially
those with highlevel semantic should be clearly defined to prevent from
confusion and abuse.  Therefore I propose dropping GFP_TEMPORARY and
replace all existing users to simply use GFP_KERNEL.  Please note that
SLAB users with shrinkers will still get __GFP_RECLAIMABLE heuristic and
so they will be placed properly for memory fragmentation prevention.

I can see reasons we might want some gfp flag to reflect shorterm
allocations but I propose starting from a clear semantic definition and
only then add users with proper justification.

This was been brought up before LSF this year by Matthew [1] and it
turned out that GFP_TEMPORARY really doesn't have a clear semantic.  It
seems to be a heuristic without any measured advantage for most (if not
all) its current users.  The follow up discussion has revealed that
opinions on what might be temporary allocation differ a lot between
developers.  So rather than trying to tweak existing users into a
semantic which they haven't expected I propose to simply remove the flag
and start from scratch if we really need a semantic for short term
allocations.

From 6faadbbb7f9da70ce484f98f72223c20125a1009 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Thu, 14 Sep 2017 11:59:30 +0200
Subject: dmi: Mark all struct dmi_system_id instances const

... and __initconst if applicable.

Based on similar work for an older kernel in the Grsecurity patch.

[JD: fix toshiba-wmi build]
[JD: add htcpen]
[JD: move __initconst where checkscript wants it]

Subject: tg3: clean up redundant initialization of tnapi

tnapi is being initialized and then immediately updated and
hence the initialiation is redundant.  Clean up the warning
by moving the declaration and initialization to the inside
of the for-loop.

Cleans up clang scan-build warning:
warning: Value stored to 'tnapi' during its initialization is never read

Subject: scsi: acornscsi: fix build error

A cleanup patch introduced a fatal typo from inbalanced curly braces:

drivers/scsi/arm/acornscsi.c: In function 'acornscsi_host_reset':
drivers/scsi/arm/acornscsi.c:2773:1: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]
drivers/scsi/arm/acornscsi.c:2795:12: error: invalid storage class for function 'acornscsi_show_info'
 static int acornscsi_show_info(struct seq_file *m, struct Scsi_Host *instance)

The same patch incorrectly changed the argument type of the reset
handler, as shown by this warning:

drivers/scsi/arm/acornscsi.c:2888:27: error: initialization of 'int (*)(struct scsi_cmnd *)' from incompatible pointer type 'int (*)(struct Scsi_Host *)' [-Werror=incompatible-pointer-types]
  .eh_host_reset_handler = acornscsi_host_reset,

This removes one the extraneous opening brace and reverts the
argument type change.

[mkp: fixed checkpatch complaint]

Subject: Revert "PCI: Avoid race while enabling upstream bridges"

This reverts commit 40f11adc7cd9281227f0a6a627d966dd0a5f0cd9.

Jens found that iwlwifi firmware loading failed on a Lenovo X1 Carbon,
gen4:

  iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-34.ucode failed with error -2

He bisected it to 40f11adc7cd9 ("PCI: Avoid race while enabling upstream
bridges").  Revert that commit to fix the regression.

Subject: scsi: sg: fixup infoleak when using SG_GET_REQUEST_TABLE

When calling SG_GET_REQUEST_TABLE ioctl only a half-filled table is
returned; the remaining part will then contain stale kernel memory
information.  This patch zeroes out the entire table to avoid this
issue.

Subject: net: vrf: avoid gcc-4.6 warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building an allmodconfig kernel with gcc-4.6, we get a rather
odd warning:

drivers/net/vrf.c: In function ‘vrf_ip6_input_dst’:
drivers/net/vrf.c:964:3: error: initialized field with side-effects overwritten [-Werror]
drivers/net/vrf.c:964:3: error: (near initialization for ‘fl6’) [-Werror]

I have no idea what this warning is even trying to say, but it does
seem like a false positive. Reordering the initialization in to match
the structure definition gets rid of the warning, and might also avoid
whatever gcc thinks is wrong here.

Subject: net: systemport: Fix 64-bit stats deadlock

We can enter a deadlock situation because there is no sufficient protection
when ndo_get_stats64() runs in process context to guard against RX or TX NAPI
contexts running in softirq, this can lead to the following lockdep splat and
actual deadlock was experienced as well with an iperf session in the background
and a while loop doing ifconfig + ethtool.

So just remove the u64_stats_update_begin()/end() pair in ndo_get_stats64()
since it does not appear to be useful for anything. No inconsistency was
observed with either ifconfig or ethtool, global TX counts equal the sum of
per-queue TX counts on a 32-bit architecture.

Subject: net: smsc911x: Quieten netif during suspend

If the network interface is kept running during suspend, the net core
may call net_device_ops.ndo_start_xmit() while the Ethernet device is
still suspended, which may lead to a system crash.

E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
driven by a PM controlled clock.  If the Ethernet registers are accessed
while the clock is not running, the system will crash with an imprecise
external abort.

As this is a race condition with a small time window, it is not so easy
to trigger at will.  Using pm_test may increase your chances:

    # echo 0 > /sys/module/printk/parameters/console_suspend
    # echo platform > /sys/power/pm_test
    # echo mem > /sys/power/state

To fix this, make sure the network interface is quietened during
suspend.

The driver doesn't support events from address families other than IPv4
and IPv6, so ignore them. Otherwise, we risk queueing a work item before
it's initialized.

This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES
is enabled, as the VRF driver will try to add an l3mdev rule for the
IPMR family.

Commit 5620a0d1aac ("firmware: delete in-kernel firmware") removed the
entire firmware directory.  Unfortunately it thereby also removed the
support for built-in firmware.

This restores the ability to build firmware directly into the kernel by
pruning the original Makefile to the necessary minimum.  The default for
EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

Subject: dma-coherent: fix rmem_dma_device_init regression

My recent bug fix introduced another bug, which caused rmem_dma_device_init
to always fail, as rmem->priv is never set to anything.

This restores the previous behavior, calling dma_init_coherent_memory()
whenever ->priv is NULL.

Subject: clocksource/integrator: Fix section mismatch warning

gcc-4.6 and older fail to inline integrator_clocksource_init, so they
end up showing a harmless warning:

WARNING: vmlinux.o(.text+0x4aa94c): Section mismatch in reference from the function integrator_clocksource_init() to the function .init.text:clocksource_mmio_init()
The function integrator_clocksource_init() references
the function __init clocksource_mmio_init().
This is often because integrator_clocksource_init lacks a __init
annotation or the annotation of clocksource_mmio_init is wrong.

Add the missing __init annotation that makes it build cleanly with all
compilers.

Subject: mtd: spi-nor: Check consistency of the memory size extracted from the
 SFDP

One field of the flash parameter table contains information about the
flash device size.
Most of the time the data extracted from this field is valid, but
sometimes the BFPT section of the SFDP table is corrupted or invalid and
this field is set to 0xffffffff, thus resulting in an integer overflow
when setting params->size.

Since NOR devices are anayway always smaller than 2^64 bytes, we can
easily stop the BFPT parsing if the size reported in this table is
invalid.

Subject: mtd: spi-nor: fix DMA unsafe buffer issue in spi_nor_read_sfdp()

spi_nor_read_sfdp() calls nor->read() to read the SFDP data.
When the m25p80 driver is used (pretty common case), nor->read() is then
implemented by the m25p80_read() function, which is likely to initialize a
'struct spi_transfer' from its buf argument before appending this
structure inside the 'struct spi_message' argument of spi_sync().

Besides the SPI sub-system states that both .tx_buf and .rx_buf members of
'struct spi_transfer' must point into dma-safe memory. However, two of the
three calls of spi_nor_read_sfdp() were given pointers to stack allocated
memory as buf argument, hence not in a dma-safe area.
Hopefully, the third and last call of spi_nor_read_sfdp() was already
given a kmalloc'ed buffer argument, hence dma-safe.

So this patch fixes this issue by introducing a
spi_nor_read_sfdp_dma_unsafe() function which simply wraps the existing
spi_nor_read_sfdp() function and uses some kmalloc'ed memory as a bounce
buffer.

Subject: drm/i915/gvt: Fix incorrect PCI BARs reporting

Looking at our virtual PCI device, we can see surprising Region 4 and Region 5.
00:10.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 06) (prog-if 00 [VGA controller])
        ....
        Region 0: Memory at 140000000 (64-bit, non-prefetchable) [size=16M]
        Region 2: Memory at 180000000 (64-bit, prefetchable) [size=1G]
        Region 4: Memory at <ignored> (32-bit, non-prefetchable)
        Region 5: Memory at <ignored> (32-bit, non-prefetchable)
        Expansion ROM at febd6000 [disabled] [size=2K]

The fact is that we only implemented BAR0 and BAR2. Surprising Region 4 and
Region 5 are shown because we report their size as 0xffffffff. They should
report size 0 instead.

BTW, the physical GPU has a PIO BAR. GVTg hasn't implemented PIO access, so
we ignored this BAR for vGPU device.

v2: fix BAR size value calculation.

Subject: Revert "drm/i915/bxt: Disable device ready before shutdown command"

This reverts commit bbdf0b2ff32a ("drm/i915/bxt: Disable device ready
before shutdown command").

Disable device ready before shutdown command was added previously to
avoid a split screen issue seen on dual link DSI panels. As of now, dual
link is not supported and will need some rework in the upstream
code. For single link DSI panels, the change is not required. This will
cause failure in sending SHUTDOWN packet during disable. Hence reverting
the change. Will handle the change as part of dual link enabling in
upstream.

Commit 1bf6ad622b9b ("drm/vblank: drop the mode argument from

did not remove the local variable. Do so now.

Subject: ACPI / watchdog: properly initialize resources

We copy a local resource structure into a list, but only
initialize some of its members, as pointed out by gcc-4.4:

drivers/acpi/acpi_watchdog.c: In function 'acpi_watchdog_init':
drivers/acpi/acpi_watchdog.c:105: error: 'res.child' may be used uninitialized in this function
drivers/acpi/acpi_watchdog.c:105: error: 'res.sibling' may be used uninitialized in this function
drivers/acpi/acpi_watchdog.c:105: error: 'res.parent' may be used uninitialized in this function
drivers/acpi/acpi_watchdog.c:105: error: 'res.desc' may be used uninitialized in this function
drivers/acpi/acpi_watchdog.c:105: error: 'res.name' may be used uninitialized in this function

Newer compilers can presumably optimize the uninitialized access
away entirely and don't warn at all, but rely on the kzalloc()
to zero the structure first. This adds an explicit initialization
to force consistent behavior.

Maurice reports:

    BUG: unable to handle kernel NULL pointer dereference at 0000000000000028
    IP: holder_class_store+0x253/0x2b0 [libnvdimm]

...while trying to reconfigure an NVDIMM-N namespace into 'sector' /
'btt' mode. The crash points to this line:

    (gdb) li *(holder_class_store+0x253)
    0x7773 is in holder_class_store (drivers/nvdimm/namespace_devs.c:1420).

    1419
    1420                    nsindex = to_namespace_index(ndd, ndd->ns_current);

...where we are failing because ndd is NULL due to NVDIMM-N dimms not
supporting labels.

Long story short, default to the BTTv1 format in the label-less /
NVDIMM-N case.

It seems we have to be more careful in napi_complete_done()
use. This patch is not a revert, as it seems we can
avoid bug that Ville reported by moving the napi_complete_done()
test in the spinlock section.

Many thanks to Ville for detective work and all tests.

Subject: net: systemport: Fix 64-bit statistics dependency

There are several problems with commit 10377ba7673d ("net: systemport:
Support 64bit statistics", first one got fixed in 7095c973453e ("net:
systemport: Fix 64-bit stats deadlock").

The second problem is that this specific code updates the
stats64.tx_{packets,bytes} from ndo_get_stats64() and that is what we
are returning to ethtool -S. If we are not running a tool that involves
calling ndo_get_stats64(), then we won't get updated ethtool stats.

The solution to this is to update the stats from both call sites,
factoring that into a specific function, While at it, don't just check
the sizeof() but also the type of the statistics in order to use the
64-bit stats seqlock.

Subject: iommu: Add missing dependencies

parisc:allmodconfig, xtensa:allmodconfig, and possibly others generate
the following Kconfig warning.

warning: (IPMMU_VMSA && ARM_SMMU && ARM_SMMU_V3 && QCOM_IOMMU) selects
IOMMU_IO_PGTABLE_LPAE which has unmet direct dependencies (IOMMU_SUPPORT &&
HAS_DMA && (ARM || ARM64 || COMPILE_TEST && !GENERIC_ATOMIC64))

IOMMU_IO_PGTABLE_LPAE depends on (COMPILE_TEST && !GENERIC_ATOMIC64),
so any configuration option selecting it needs to have the same dependencies.

Subject: iommu/vt-d: Fix harmless section mismatch warning

Building with gcc-4.6 results in this warning due to
dmar_table_print_dmar_entry being inlined as in newer compiler versions:

WARNING: vmlinux.o(.text+0x5c8bee): Section mismatch in reference from the function dmar_walk_remapping_entries() to the function .init.text:dmar_table_print_dmar_entry()
The function dmar_walk_remapping_entries() references
the function __init dmar_table_print_dmar_entry().
This is often because dmar_walk_remapping_entries lacks a __init
annotation or the annotation of dmar_table_print_dmar_entry is wrong.

This removes the __init annotation to avoid the warning. On compilers
that don't show the warning today, this should have no impact since the
function gets inlined anyway.

Subject: drm/exynos: Fix locking in the suspend/resume paths

Commit 48a92916729b ("drm/exynos: use drm_for_each_connector_iter()")
replaced unsafe drm_for_each_connector() with drm_for_each_connector_iter()
and removed surrounding drm_modeset_lock calls. However, that lock was
there not only to protect unsafe drm_for_each_connector(), but it was also
required to be held by the dpms code which was called from the loop body.
This patch restores those drm_modeset_lock calls to fix broken suspend
and resume of Exynos DRM subsystem in v4.13 kernel.

Subject: drm/exynos: Fix suspend/resume support

Commit 7d902c05b480 ("drm: Nuke drm_atomic_helper_connector_dpms")
removed drm_atomic_helper_connector_dpms() helper saying that it was a dead
code. It was however indirectly used by Exynos DRM driver for implementing
suspend/resume support. To fix this regression (after that patch Exynos DRM
suspend/resume functions became no-ops and hardware fails to suspend),
this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.

Subject: irqchip/gic-v3: Iterate over possible CPUs by for_each_possible_cpu()

get_cpu_number() doesn't use existing helper to iterate over possible
CPUs, It will cause an error in case of discontinuous @cpu_possible_mask
such as 0b11110001, which can result from a core having failed to come
up on a SMP machine.

Fixed by using existing helper for_each_possible_cpu().

Subject: irqchip.mips-gic: Fix shared interrupt mask writes

The write_gic_smask() & write_gic_rmask() functions take a shared
interrupt number as a parameter, but we're incorrectly providing them a
bitmask with the shared interrupt's bit set. This effectively means that
we mask or unmask the shared interrupt 1<<n rather than shared interrupt
n, and as a result likely drop interrupts.

Subject: ACPI / bus: Make ACPI_HANDLE() work for non-GPL code again

Due to commit db3e50f3234b (device property: Get rid of struct
fwnode_handle type field), ACPI_HANDLE() inadvertently became
a GPL-only call. The call path that led to that was:

ACPI_HANDLE()
    ACPI_COMPANION()
        to_acpi_device_node()
            is_acpi_device_node()
                acpi_device_fwnode_ops
                    DECLARE_ACPI_FWNODE_OPS(acpi_device_fwnode_ops);

...and the new DECLARE_ACPI_FWNODE_OPS() includes
EXPORT_SYMBOL_GPL, whereas previously it was a static struct.

In order to avoid changing any of that, let's instead provide ever
so slightly better encapsulation of those struct fwnode_operations
instances. Those do not really need to be directly used in
inline function calls in header files. Simply moving two small
functions (is_acpi_device_node and is_acpi_data_node) out of
acpi_bus.h, and into a .c file, does that.

That leaves the internals of struct fwnode_operations as GPL-only
(which I think was the intent all along), but un-breaks any driver
code out there that relies on the ACPI subsystem's being (historically)
an EXPORT_SYMBOL-usable system. By that, I mean, ACPI_HANDLE() and
other basic ACPI calls were non-GPL-protected.

Also, while I'm there, remove a tiny bit of redundancy that was missed
in the earlier commit, by having is_acpi_node() use the other two
routines, instead of checking fwnode directly.

Subject: net: phy: Kconfig: Fix PHY infrastructure menu in menuconfig

Since the integration of PHYLINK, the configuration option which
used to be under the PHY infrastructure menu in menuconfig ended
up one level up (the network device driver section)

By placing PHYLINK option right after PHYLIB entry, it broke the
way Kconfig used to build the menu. See kconfig-language.txt, section
"Menu structure", 2nd method.

This is fixed by placing the PHYLINK option just before PHYLIB.

no_pm_callbacks flag for the device incorrectly and then the
callbacks may be skipped during system suspend/resume, which
shouldn't happen.

Commit edeec420de24 (cpufreq: dt-platdev: Automatically create cpufreq
device with OPP v2) missed adding few platforms to the blacklist which
create the cpufreq-dt device from their own drivers, after some
dependencies are sorted out.

And for those platforms, both the platform specific driver and the
cpufreq-dt-platdev driver try to create the cpufreq-dt device now.

Fix that by including those platforms in the blacklist. This doesn't include
the TI platforms, for which there is a separate patch.

Subject: ACPI: properties: Return _DSD hierarchical extension (data) sub-nodes
 correctly

The recently merged patch "ACPI: Prepare for constifying
acpi_get_next_subnode() fwnode argument" was part of a patchset
constifying the fwnode arguments across the fwnode property API. The
purpose of the patch was to allow returning non-const fwnodes from a data
structure the root of which is const.

Unfortunately the patch introduced the functionality, in particular when
starting parsed from an ACPI device node, the hierarchical data extension
nodes would not be enumerated.

Restore the old behaviour while still retaining constness properties of
the patch.

Subject: cpufreq: ti-cpufreq: Support additional am43xx platforms

Rather than letting the ti-cpufreq driver match against 'ti,am4372'
machine compatible during probe let's match against 'ti,am43' so that we
can support both 'ti,am4372' and 'ti,am438x' platforms which both match
to this compatible.

Subject: net: hns3: Fixes the premature exit of loop when matching clients

When register/unregister ae_dev, ae_dev should match all client
in the client_list. Enet and roce can co-exists together so we
should continue checking for enet and roce presence together.
So break should not be there.

Above caused problems in loading and unloading of modules.

Subject: net: emac: Fix napi poll list corruption

This patch is pretty much a carbon copy of
commit 3079c652141f ("caif: Fix napi poll list corruption")
with "caif" replaced by "emac".

The commit d75b1ade567f ("net: less interrupt masking in NAPI")
breaks emac.

It is now required that if the entire budget is consumed when poll
returns, the napi poll_list must remain empty.  However, like some
other drivers emac tries to do a last-ditch check and if there is
more work it will call napi_reschedule and then immediately process
some of this new work.  Should the entire budget be consumed while
processing such new work then we will violate the new caller
contract.

This patch fixes this by not touching any work when we reschedule
in emac.

Function hdmi_mode_fixup() used bare list_for_each entry, which was
unsafe and caused memory corruption detected by kasan.
It now uses drm_for_each_connector_iter macro, which is now recommended
by the documentation and safe.

Subject: crypto: talitos - Don't provide setkey for non hmac hashing algs.

Today, md5sum fails with error -ENOKEY because a setkey

splice(4, NULL, 7, NULL, 262144, SPLICE_F_MORE) = -1 ENOKEY (Required key not available)

munmap(0x77f50000, 378880)              = 0

This patch ensures that setkey() function is set only
for hmac hashing.

When built using multi_v7_defconfig, driver does not work on LS1021A:

Subject: PCI: endpoint: Use correct "end of test" interrupt

pci_epf_test_raise_irq() reads the interrupt to use for the response from
reg->command, but this has been cleared at the beginning of the command
handler so the value is always zero at this point.

Instead, extract the interrupt index before handling the command and then
pass the requested interrupt into pci_epf_test_raise_irq().  This allows us
to remove the specific code to extract the interrupt for
COMMAND_RAISE_MSI_IRQ since it is now handled in common code.

Fixes: 3ecf3232c54c ("PCI: endpoint: Do not reset *command* inadvertently")

Subject: isdn/i4l: fetch the ppp_write buffer in one shot

In isdn_ppp_write(), the header (i.e., protobuf) of the buffer is
fetched twice from userspace. The first fetch is used to peek at the
protocol of the message and reset the huptimer if necessary; while the
second fetch copies in the whole buffer. However, given that buf resides
in userspace memory, a user process can race to change its memory content
across fetches. By doing so, we can either avoid resetting the huptimer
for any type of packets (by first setting proto to PPP_LCP and later
change to the actual type) or force resetting the huptimer for LCP
packets.

This patch changes this double-fetch behavior into two single fetches
decided by condition (lp->isdn_device < 0 || lp->isdn_channel <0).
A more detailed discussion can be found at

Subject: net: hns3: Cleanup for ROCE capability flag in ae_dev

This patch add the ROCE supported flag in the driver_data
field of pci_device_id, delete roce_pci_tbl and change
HNAE_DEV_SUPPORT_ROCE_B to HNAE3_DEV_SUPPORT_ROCE_B.
This cleanup is done in order to support adding capability
in pci_device_id and to fix initialization failure when
cmd is not supported.

Subject: net: hns3: Fix initialization when cmd is not supported

When ae_dev doesn't support DCB, rx_priv_wl_config,
common_thrd_config and tm_qs_bp_cfg can't be called, otherwise
cmd return fail, which causes the hclge module initialization
process to fail.
This patch fix it by adding a DCB capability flag to check if
the ae_dev support DCB.

Subject: net: hns3: Fix for not setting rx private buffer size to zero

When rx private buffer is disabled, there may be some case that

allocation process to fail.
This patch fixes this problem by setting priv->enable to 0 and
priv->buf_size to zero when rx private buffer is disabled.

used for rx direction, right now only the private buffer is

For ae_dev that doesn't support DCB, private rx buffer is assigned
to zero, only shared rx buffer is used. So not setting the shared
rx buffer cause dropping of packet in SSU.

Subject: net: hns3: Fix for setting rss_size incorrectly

rss_size is 1, 2, 4, 8, 16, 32, 64, 128, but acutal tc queue
size can be any u16 less than 128. If tc queue size is 5, we
set the rss_size to 8, indirection table will be used to limit
the size of actual queue size.
It may cause dropping of receiving packet in hardware if
rss_size is not set correctly.
For now, each TC has the same rss size.

Subject: hv_netvsc: fix send buffer failure on MTU change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If MTU is changed the host would reject the send buffer change.
This problem is result of recent change to allow changing send
buffer size.

Every time we change the MTU, we store the previous net_device section
count before destroying the buffer, but we don’t store the previous
section size. When we reinitialize the buffer, its size is calculated
by multiplying the previous count and previous size. Since we
continuously increase the MTU, the host returns us a decreasing count
value while the section size is reinitialized to 1728 bytes every
time.

This eventually leads to a condition where the calculated buf_size is
so small that the host rejects it.

Subject: net: qcom/emac: add software control for pause frame mode

The EMAC has the option of sending only a single pause frame when
flow control is enabled and the RX queue is full.  Although sending
only one pause frame has little value, this would allow admins to
enable automatic flow control without having to worry about the EMAC
flooding nearby switches with pause frames if the kernel hangs.

The option is enabled by using the single-pause-mode private flag.

Subject: net: phy: Keep reporting transceiver type

With commit 2d55173e71b0 ("phy: add generic function to support
ksetting support"), we lost the ability to report the transceiver type
like we used to. Now that we have added back the transceiver type to
ethtool_link_settings, we can report it back like we used to and have no
loss of information.

Subject: Input: uinput - avoid FF flush when destroying device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Normally, when input device supporting force feedback effects is being
destroyed, we try to "flush" currently playing effects, so that the
physical device does not continue vibrating (or executing other effects).
Unfortunately this does not work well for uinput as flushing of the effects
deadlocks with the destroy action:

- if device is being destroyed because the file descriptor is being closed,
  then there is noone to even service FF requests;

- if device is being destroyed because userspace sent UI_DEV_DESTROY,
  while theoretically it could be possible to service FF requests,
  userspace is unlikely to do so (they'd need to make sure FF handling
  happens on a separate thread) even if kernel solves the issue with FF
  ioctls deadlocking with UI_DEV_DESTROY ioctl on udev->mutex.

To avoid lockups like the one below, let's install a custom input device
flush handler, and avoid trying to flush force feedback effects when we
destroying the device, and instead rely on uinput to shut off the device
properly.

Subject: Input: uinput - avoid crash when sending FF request to device going
 away

If FF request comes in while uinput device is going away,
uinput_request_send() will fail with -ENODEV, and uinput_request_submit()
will attempt to mark the slot as unused by calling uinput_request_done().
Unfortunately in this case we haven't initialized request->done completion
yet, and we get a crash:

While we could solve this by simply initializing the completion earlier, we
are better off rearranging the code a bit so we avoid calling complete() on
requests that we did not send out. This patch consolidates marking request
slots as free in one place (in uinput_request_submit(), the same place
where we acquire them) and having everyone else simply signal completion
of the requests.

Subject: net: phy: Fix truncation of large IRQ numbers in phy_attached_print()

Given NR_IRQS is 2048 on sparc64, and even 32784 on alpha, 3 digits is
not enough to represent interrupt numbers on all architectures.  Hence
PHY interrupt numbers may be truncated during printing.

Increase the buffer size from 4 to 8 bytes to fix this.

Subject: iommu/of: Remove PCI host bridge node check

of_pci_iommu_init() tries to be clever and stop its alias walk at the
device represented by master_np, in case of weird PCI topologies where
the bridge to the IOMMU and the rest of the system is not at the root.
It turns out this is a bit short-sighted, since there are plenty of
other callers of pci_for_each_dma_alias() which would also need the same
behaviour in that situation, and the only platform so far with such a
topology (Cavium ThunderX2) already solves it more generally via a PCI
quirk. As this check is effectively redundant, and returning a boolean
value as an int is a bit broken anyway, let's just get rid of it.

If the thread waiting for a CLOSE_LISTSRV_RPL times out and bails,
then we need to handle a subsequent CPL if it arrives and the stid has
been released.  In this case silently drop it.

If a listen create fails, then the server tid (stid) is incorrectly left
in the stid idr table, which can cause a touch-after-free if the stid
is looked up and the already freed endpoint is touched.  So make sure
and remove it in the error path.

In the case where mbox_status is OCRDMA_MBX_STATUS_FAILED and

however the case OCRDMA_MBX_STATUS_FAILED is missing a break and
falls through to the default case which then re-assigns err_num
to -EFAULT.   Fix this so that err_num is assigned to -EAGAIN
for the add_status OCRDMA_MBX_STATUS_FAILED case and -EFAULT
otherwise.

Subject: IB/mlx5: fix debugfs cleanup

If delay_drop_debugfs_init() fails in any of the operations to create
debugfs, it is calling delay_drop_debugfs_cleanup() as part of its
cleanup. But delay_drop_debugfs_cleanup() checks for 'dbg' and since
we have not yet pointed 'dbg' to the debugfs we need to cleanup, the
cleanup fails and we are left with stray debugfs elements and also a
memory leak.

Subject: i40iw: Prevent multiple netdev event notifier registrations

Netdev event notifier registration/de-registration is not
synchronized with a lock and there is a possibility of a
duplicate registration of notifier before the unregister
completes.

Register netdev event notifiers during module init and
de-register them at module exit.

This avoids the need to tie the registration to first netdev
client interface open and de-registration to last client
interface close and the synchronization to achieve it.

This also fixes a crash due to duplicate registration.

If QP modify to closing/terminate/error fails, connection is
not torn down as there is no corresponding asynchronous
event that will initiate the teardown.

Add explicit call to i40iw_cm_disconn if not waiting in
modify QP, otherwise schedule it in CM timer.

Subject: i40iw: Add support for port reuse on active side connections

During OpenMPI scale up testing, we observe rdma_connect
failures if ports are reused on multiple connections.
This is because the Control Queue-Pair (CQP) command to add
the reused port to Accelerated Port Bit VectorTable (APBVT)
fails as there already exists an entry.

Check for duplicate port before invoking the CQP command
to add APBVT entry and delete the entry only if the port
is not in use.

Subject: bnxt_re: Stop issuing further cmds to FW once a cmd times out

Once a cmd to FW times out(after 20s) it is reasonable to
assume the FW or atleast the control path is dead.
No point issuing further cmds to the FW as each subsequent cmd
with another 20s timeout will cascade resulting in unnecessary
traces and/or NMI Lockups.

Subject: bnxt_re: Fix race between the netdev register and unregister events

Upon receipt of the NETDEV_REGISTER event from the netdev notifier chain,
the IB stack registration is spawned off to a workqueue since that also
requires an rtnl lock.
There could be 2 kinds of races between the NETDEV_REGISTER and the
NETDEV_UNREGISTER event handling.
a)The NETDEV_UNREGISTER event is received in rapid succession after
the NETDEV_REGISTER event even before the work queue got a chance to run.
b)The NETDEV_UNREGISTER event is received while the workqueue that handles
registration with the IB stack is still in progress.

Handle both the races with a bit flag that is set just before the work item
is queued and cleared in the workqueue after the event is handled just
before the workqueue item is freed.

While adding the new flag, it was noted that the flags are all used in
*_bit() operations which expect a bit number and not a literal constant
with a bit set.  So change the numbers to be bit numbers.

Subject: bnxt_re: Remove RTNL lock dependency in bnxt_re_query_port

When there is a NETDEV_UNREGISTER event, bnxt_re driver calls
ib_unregister_device() (RTNL lock held).
ib_unregister_device attempts to flush a worker queue scheduled by
ib_core and that queue might have a pending ib_query_port().
ib_query_port in turn calls bnxt_re_query_port(), which while querying the
link speed using ib_get_eth_speed(), tries to acquire the rtnl_lock() which
was already held by NETDEV_UNREGISTER.
Fixing the issue by removing the link speed query from bnxt_re_query_port()
Now the speed is queried post a successful ib_register_device or whenever
there is a NETDEV_CHANGE event.

Subject: bnxt_re: Fix memory leak in FRMR path

This patch fixes a memory leak issue when alloc_mr is used.
mr->pages and mr->npages are used only in alloc_mr path. mr->pages
is allocated when alloc_mr is called or in the case of FRMR, while
creating the MR. mr->npages is updated only when the MR created
is used i.e. after invoking map_mr_sg verb, before data transfer.
In the dereg_mr path, if mr->npages is 0, driver ends up not freeing
the memory created.
Removing the npages check from the dereg_mr path for kernel consumers.

Subject: tpm: replace msleep() with  usleep_range() in TPM 1.2/2.0 generic
 drivers

The patch simply replaces all msleep function calls with usleep_range calls
in the generic drivers.

Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a
thousand PCR extends, we see results going from 1m57s unpatched to 40s
with the new patch. We obtain similar results when using the original and
patched tpm_infineon driver, which is also part of the patch.
Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per
extend unpatched and around 7ms with the new patch.

Note that the PCR consistency is untouched with this patch, each TPM has
been tested with 10 million extends and the aggregated PCR value is
continuously verified to be correct.

As an extension of this work, this could potentially and easily be applied
to other vendor's drivers. Still, these changes are not included in the
proposed patch as they are untested.

Subject: tpm: ibmvtpm: simplify crq initialization and document crq format

The crq is passed in registers and is the same on BE and LE hosts.
However, current implementation allocates a structure on-stack to
represent the crq, initializes the members swapping them to BE, and
loads the structure swapping it from BE. This is pointless and causes
GCC warnings about ununitialized members. Get rid of the structure and
the warnings.
