Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v3.16 series.
There is a lot of action in the GPIO subsystem doing refactorings and
cleanups, almost as many deletions as insertions and minor feature
growth and no new drivers this time. Which is actually pretty nice.
Some GPIO-related stuff will come in through the pin control tree as
well.
Details:
- We are finalizing and fixing up the gpiochip irqchip helpers
bringing a helpful irqchip implementation into the gpiolib core and
avoiding duplicate code and, more importantly, duplicate bug fixes:
* Support for using the helpers with threaded interrupt handlers as
used on sleeping GPIO-irqchips
* Do not set up hardware triggers for edges or levels if the
default IRQ type is IRQ_TYPE_NONE - some drivers would exploit
the fact that you could get default initialization of the IRQ
type from the core at probe() but if no default type is set up
from the helper, we should not call the driver to configure
anything. Wait until a consumer requests the interrupt instead.
* Make the irqchip helpers put the GPIO irqs into their own lock
class. The GPIO irqchips can often emit (harmless, but annoying)
lockdep warnings about recursions when they are in fact just
cascaded IRQs. By putting them into their own lock class we help
the lockdep core to keep track of things.
* Switch the tc3589x GPIO expanders to use the irqchip helpers
* Switch the OMAP GPIO driver to use the irqchip helpers
* Add some documentation for the irqchip helpers
* select IRQ_DOMAIN when using the helpers since some platforms may
not be using this by default and it's a strict dependency.
- Continued GPIO descriptor refactoring:
* Remove the one instance of gpio_to_desc() from the device tree
code, making the OF GPIO code use GPIO descriptors only.
* Introduce gpiod_get_optional() and gpiod_get_optional_index()
akin to the similar regulator functions for cases where the use
of GPIO is optional and not strictly required.
* Make of_get_named_gpiod_flags() private - we do not want to
unnecessarily expose APIs to drivers that make the gpiolib harder
than necessary to maintain and refactor. Privatize this
function.
- Support "-gpio" suffix for the OF GPIO retrieveal path. We used to
look for "foo-gpios" or just "gpios" in device tree nodes, but it
turns out that some drivers with a single GPIO line will just state
"foo-gpio" (singularis). Sigh. Support this with a fallback
looking for it, as this simplifies driver code and handles it in
core code.
- Switch the ACPI GPIO core to fetch GPIOs with the *_cansleep
function variants as the GPIO operation region handler can sleep,
and shall be able to handle gpiochips that sleep.
- Tons of cleanups and janitorial work from Jingoo Han, Axel Lin,
Javier Martinez Canillas and Abdoulaye Berthe. Notably Jingoo cut
off a ton of pointless OOM messages.
- Incremental development and fixes for various drivers, nothing
really special here"

The 16-bit DMA support doesn't fit well within the SPI core DMA framework,
as it needs to manage its own double-sized temporary buffers, for handling
the interleaved data.
Remove it, as there is no in-tree board code that sets
rspi_plat_data.dma_width_16bit.

Commit 9739eef13c92 ("net: filter: make BPF conversion more readable")
started to introduce helper macros similar to BPF_STMT()/BPF_JUMP()
macros from classic BPF.
However, quite some statements in the filter conversion functions
remained in the old style which gives a mixture of block macros and
non block macros in the code. This patch makes the block macros itself
more readable by using explicit member initialization, and converts
the remaining ones where possible to remain in a more consistent state.

This patch finally allows us to get rid of the BPF_S_* enum.
Currently, the code performs unnecessary encode and decode
workarounds in seccomp and filter migration itself when a filter
is being attached in order to overcome BPF_S_* encoding which
is not used anymore by the new interpreter resp. JIT compilers.
Keeping it around would mean that also in future we would need
to extend and maintain this enum and related encoders/decoders.
We can get rid of all that and save us these operations during
filter attaching. Naturally, also JIT compilers need to be updated
by this.
Before JIT conversion is being done, each compiler checks if A
is being loaded at startup to obtain information if it needs to
emit instructions to clear A first. Since BPF extensions are a
subset of BPF_LD | BPF_{W,H,B} | BPF_ABS variants, case statements
for extensions can be removed at that point. To ease and minimalize
code changes in the classic JITs, we have introduced bpf_anc_helper().
Tested with test_bpf on x86_64 (JIT, int), s390x (JIT, int),
arm (JIT, int), i368 (int), ppc64 (JIT, int); for sparc we
unfortunately didn't have access, but changes are analogous to
the rest.

The “affinity hint” mechanism is used by the user space
daemon, irqbalancer, to indicate a preferred CPU mask for irqs.
Irqbalancer can use this hint to balance the irqs between the
cpus indicated by the mask.
We wish the HCA to preferentially map the IRQs it uses to numa cores
close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that
sets the affinity hint according the following policy:
First it maps IRQs to “close” numa cores. If these are exhausted, the
remaining IRQs are mapped to “far” numa cores.

This function sets the n'th cpu - local cpu's first.
For example: in a 16 cores server with even cpu's local, will get the
following values:
cpumask_set_cpu_local_first(0, numa, cpumask) => cpu 0 is set
cpumask_set_cpu_local_first(1, numa, cpumask) => cpu 2 is set
...
cpumask_set_cpu_local_first(7, numa, cpumask) => cpu 14 is set
cpumask_set_cpu_local_first(8, numa, cpumask) => cpu 1 is set
cpumask_set_cpu_local_first(9, numa, cpumask) => cpu 3 is set
...
cpumask_set_cpu_local_first(15, numa, cpumask) => cpu 15 is set
Curently this function will be used by multi queue networking devices to
calculate the irq affinity mask, such that as many local cpu's as
possible will be utilized to handle the mq device irq's.

It is reported that Linux x86 kernel cannot map large tables. The following
large SSDT table on such platform fails to pass checksum verification and
cannot be installed:
ACPI: SSDT 0x00000000B9638018 07A0C4 (v02 INTEL S2600CP 00004000 INTL 20100331)
It sounds strange that in the 64-bit virtual memory address space, we
cannot map a single ACPI table to do checksum verification. The root cause
is:
1. ACPICA doesn't split IO memory mapping and table mapping;
2. Linux x86 OSL implements acpi_os_map_memory() using a size limited fix-map
mechanism during early boot stage, which is more suitable for only IO
mappings.
ACPICA originally only mapped table header for signature validation, and
this header mapping is required by OSL override mechanism. There was no
checksum verification because we could not map the whole table using this
OSL. While the following ACPICA commit enforces checksum verification by
mapping the whole table during Linux boot stage and it finally triggers
this issue on some platforms:
Commit: 86dfc6f339886559d80ee0d4bd20fe5ee90450f0
Subject: ACPICA: Tables: Fix table checksums verification before installation.
Before doing further cleanups for the OSL table mapping and override
implementation, this patch introduces an option for such OSPMs to
temporarily discard the checksum verification feature. It then can be
re-enabled easily when the ACPICA and the underlying OSL is ready.
This patch also deletes a comment around the limitation of mappings because
it is not correct. The limitation is not how many times we can map in the
early stage, but the OSL mapping facility may not be suitable for mapping
the ACPI tables and thus may complain us the size limitation.
The acpi_tb_verify_table() is renamed to acpi_tb_verify_temp_table() due to the
work around added, it now only applies to the table descriptor that hasn't
been installed and cannot be used in other cases. Lv Zheng.

"Here I just have Heikki's rfkill GPIO cleanups.
The ARM/tegra patch is OK with the maintainer (Stephen). Let me know of
any problems."
and;
"We have a whole bunch of work on CSA by Andrei, Luca and Michal, but
unfortunately it doesn't seem quite complete yet so it's still disabled.
There's some TDLS work from Arik, and the rest is mostly minor fixes and
cleanups."
For the NFC bits, Samuel says:
"This is the NFC pull request for 3.16. We have:
- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI
sniffing from that. This can be extended to report HCI frames and also
proprietarry ones like e.g. the pn533 ones."
For the iwlwifi bits, Emmanuel says:
"Eran continues to work on new devices, Eyal is still digging in
the rate control stuff, and Johannes added new functionality to the
debug system we have in place now along with a few cleanups he made
on the way. That's pretty much it."
and;
"Avri continues to work on the power code and Eran is improving the
NVM handling as a preparations for new devices on which he works
with Liad. Luca cleans up a bit the code while working on CSA. I have
the regular BT Coex stuff and a small lockdep fix. Johannes has his
regular amount of clean ups and improvements, the main one is the
ability to leave 2 chains open to improve diversity and hence the
throughput in high attenuation scenarios."
and;
"The regular amount of housekeeping here. I merged iwlwifi-fixes.git to
be able to add the patch you didn't want in wireless.git at that stage
of the -rc cycle. Luca has a few preparations for CSA implementation
and also what seems to be a bugfix for P2P but hasn't caused issues
we could notice."
For the Atheros bits, Kalle says:
"For ath10k Michal did various small fixes on how we handle
hardware/firmware problems and he also fixed two memory leaks."
Also included are a couple of pulls from the wireless tree to
avoid/resolve merge issues...

RPC_MAX_AUTH_SIZE is scattered around several places. Better to set it
once in the auth code, where this kind of estimate should be made. And
while we're at it we can leave it zero when we're not using krb5i or
krb5p.

After this we can handle for example getattr of very large ACLs.
Read, readdir, readlink are still special cases with their own limits.
Also we can't handle a new operation starting close to the end of a

This will be used in the server side in a few cases:
- when certain operations (read, readdir, readlink) fail after
encoding a partial response.
- when we run out of space after encoding a partial response.
- in readlink, where we initially reserve PAGE_SIZE bytes for
data, then truncate to the actual size.

Currently blk-mq registers all the hardware queues in sysfs,
regardless of whether it uses them (e.g. they have CPU mappings)
or not. The unused hardware queues lack the cpux/ directories,
and the other sysfs entries (like active, pending, etc) are all
zeroes.
Change this so that sysfs correctly reflects the current mappings
of the hardware queues.

Only certain types of ACPI device objects can be enumerated as
platform devices, so in order to distinguish them from the others
introduce a new ACPI device PNP type flag, platform_id, and set it
for devices with a valid _HID to start with.
This change is based on a Zhang Rui's prototype.

ACPI can be used to enumerate PNP devices, but the code does not
handle this in the right way currently. Namely, if an ACPI device
object
1. Has a _CRS method,
2. Has an identification of
"three capital characters followed by four hex digits",
3. Is not in the excluded IDs list,
it will be enumerated to PNP bus (that is, a PNP device object will
be create for it). This means that, actually, the PNP bus type is
used as the default bus type for enumerating _HID devices in ACPI.
However, more and more _HID devices need to be enumerated to the
platform bus instead (that is, platform device objects need to be
created for them). As a result, the device ID list in acpi_platform.c
is used to enforce creating platform device objects rather than PNP
device objects for matching devices. That list has been continuously
growing recently, unfortunately, and it is pretty much guaranteed to
grow even more in the future.
To address that problem it is better to enumerate _HID devices
as platform devices by default. To this end, change the way of
enumerating PNP devices by adding a PNP ACPI scan handler that
will use a device ID list to create PNP devices for the ACPI
device objects whose device IDs are present in that list.
The initial device ID list in the PNP ACPI scan handler contains
all of the pnp_device_id strings from all the existing PNP drivers,
so this change should be transparent to the PNP core and all of the
PNP drivers. Still, in the future it should be possible to reduce
its size by converting PNP drivers that need not be PNP for any
technical reasons into platform drivers.

kvm-next
Patch queue for ppc - 2014-05-30
In this round we have a few nice gems. PR KVM gains initial POWER8 support
as well as LE host awareness, ihe e500 targets can now properly run u-boot,
LE guests now work with PR KVM including KVM hypercalls and HV KVM guests
can now use huge pages.
On top of this there are some bug fixes.
Conflicts:
include/uapi/linux/kvm.h
|
|
We worked around some nasty KVM magic page hcall breakages:
1) NX bit not honored, so ignore NX when we detect it
2) LE guests swizzle hypercall instruction
Without these fixes in place, there's no way it would make sense to expose kvm
hypercalls to a guest. Chances are immensely high it would trip over and break.
So add a new CAP that gives user space a hint that we have workarounds for the
bugs above in place. It can use those as hint to disable PV hypercalls when
the guest CPU is anything POWER7 or higher and the host does not have fixes
in place.
