commit e046114af5fcafe8d6d3f0b6ccb99804bad34bfb upstream.
nvdimm_clear_poison cleared the user-visible badblocks, and sent
commands to the NVDIMM to clear the areas marked as 'poison', but it
neglected to clear the same areas from the internal poison_list which is
used to marshal ARS results before sorting them by namespace. As a
result, once on-demand ARS functionality was added:
37b137f nfit, libnvdimm: allow an ARS scrub to be triggered on demand
A scrub triggered from either sysfs or an MCE was found to be adding
stale entries that had been cleared from gendisk->badblocks, but were
still present in nvdimm_bus->poison_list. Additionally, the stale entries
could be triggered into producing stale disk->badblocks by simply disabling
and re-enabling the namespace or region.
This adds the missing step of clearing poison_list entries when clearing
poison, so that it is always in sync with badblocks.

commit 13f392ebc37e31568fae72a73ee378ae22a9740f upstream.
On ARM/ARM64 architectures, PCI IO ports are emulated through memory mapped
IO, by reserving a chunk of virtual address space starting at PCI_IOBASE
and by mapping the PCI host bridges memory address space driving PCI IO
cycles to it.
PCI host bridge drivers that enable downstream PCI IO cycles map the host
bridge memory address responding to PCI IO cycles to the fixed virtual
address space through the pci_remap_iospace() API.
This means that if the pci_remap_iospace() function fails, the
corresponding host bridge PCI IO resource must be considered invalid, in
that there is no way for the kernel to actually drive PCI IO transactions
if the memory addresses responding to PCI IO cycles cannot be mapped into
the CPU virtual address space.
The PCI tegra host bridge driver adds the PCI IO resource retrieved from
firmware to the host bridge resource windows even if the
pci_remap_iospace() call fails; this is an actual bug in that the PCI host
bridge would consider the PCI IO resource valid (and possibly assign it to
downstream devices) even if the kernel was not able to map the PCI host
bridge memory address driving IO cycle to the CPU virtual address space (ie
pci_remap_iospace() failures).
Add the PCI host bridge driver pci_remap_iospace() failure path and do not
add the corresponding PCI host bridge PCI IO resources retrieved through
firmware when the pci_remap_iospace() function call fails, fixing the
issue.

commit ca3b9c6b6d4db9a8ba5fc8b95664e75468c59f9f upstream.
Since the SCD_QUEUE_CFG command was introduced the driver
calls iwl_trans_txq_enable_cfg() with a NULL for scd_cfg
parameter.
This makes the transport avoid writing to the SCD pointers,
since it can cause races with firmware, which is also accessing
the registers.
The transport only updates the write pointer in that case.
Fix a wrong call to iwl_trans_txq_enable() which caused a
scd_cfg parameter to be sent to transport, resulting with an
access to SCD registers.

data queue.
Make sure that mgmt frames are sent with TID IWL_TID_NON_QOS,

commit f155d15b64e36b45ca89e3521fe0c1ccad5e5ff0 upstream.
Before commit 0861e5b8cf80 (clk: Add clk_hw OF clk providers,
2016-02-05) __of_clk_get_from_provider() would return an error
pointer of the provider's choosing if there was a provider
registered and EPROBE_DEFER otherwise. After that commit, it
would return EPROBE_DEFER regardless of whether or not the
provider returned an error. This is odd and can lead to behavior
where clk consumers keep probe deferring when they should be
seeing some other error.
Let's restore the previous behavior where we only return
EPROBE_DEFER when there isn't a provider in our of_clk_providers
list. Otherwise, return the error from the last provider we find
that matches the node.

commit 67615c588a059b731df9d019edc3c561d8006ec9 upstream.
If the firmware had set up a clock to source from PLLC, go along with
it. But if we're looking for a new parent, we don't want to switch it
to PLLC because the firmware will force PLLC (and thus the AXI bus
clock) to different frequencies during over-temp/under-voltage,
without notification to Linux.
On my system, this moves the Linux-enabled HDMI state machine and DSI1
escape clock over to plld_per from pllc_per. EMMC still ends up on
pllc_per, because the firmware had set it up to use that.

commit 6cd997db911f28f2510b771691270c52b63ed2e6 upstream.
con3270 contains an optimisation that reduces the amount of data to be
transmitted to the 3270 terminal by putting a Repeat to Address (RA)
order into the data stream. The RA order itself takes up space, so
con3270 only uses it if there's enough space left in the line
buffer. Otherwise it just pads out the line manually.
For lines that were _just_ short enough that the RA order still fit in
the line buffer, the line was instead padded with an insufficient
amount of spaces. This was caused by examining the size of the
allocated line buffer rather than the length of the string to be
displayed.
For con3270_cline_end(), we just compare against the line length. For
con3270_update_string() however that isn't available anymore, so we
check whether the Repeat to Address order is present.

con3270 only uses it if there's enough space left in the line
buffer. Otherwise it just pads out the line manually.
For lines too long to include the RA order, one byte was left
uninitialised. This was caused by an off-by-one bug in the loop that
pads out the line. Since the buffer is allocated from a common pool,
the single byte left uninitialised contained some previous buffer
content. Usually this was just a space or some character (which can
result in clutter but is otherwise harmless). Sometimes, however, it
was a Repeat to Address order, messing up the entire screen layout and
causing the display to send the entire buffer content on every
keystroke.

commit d53c51f26145657aa7c55fa396f93677e613548d upstream.
Since commit 9f3d6d7 chsc_get_channel_measurement_chars is called with
interrupts disabled during resume from hibernate. Since this function
used spin_unlock_irq, interrupts have been enabled accidentally. Fix
this by using the irqsave variant.
Since we can't guarantee the IRQ-enablement state for all (future/
external) callers, change the locking in related functions to prevent
similar bugs in the future.

commit a19440304db2d97aed5cee9bfa5017c98d2348bf upstream.
When a view destruction command was present in the command stream, the
view was validated to avoid a device error. That caused excessive and
unnecessary validations of views, surfaces and mobs on view destruction.
Replace this with a new relocation type that patches the view
destruction command to a NOP if the view is not present in the device
after the execbuf validation sequence.
Also add checks for the member size of the vmw_res_relocation struct.
Fixes sporadic command submission errors on google-earth exit.

commit 86c7e6836479c4045a9a81ed5ea76c51d719f9c1 upstream.
A workaround for a warning introduced a use of the NO_IRQ
macro that should have been gone for a long time.
It is clear from the code that the value cannot actually
be used, but apparently there was a configuration at
some point that caused a warning, so instead of just
reverting that patch, this rearranges the code in a way that
the warning cannot reappear.

commit 0610735928ee47870e083d5901caa371089216f1 upstream.
bq->charger is initialized in bq24257_power_supply_init.
Therefore, bq24257_power_supply_init should be called before the
registration of the IRQ handler bq24257_irq_handler_thread that calls
power_supply_changed(bq->charger).

commit 09951d83fc58a6f772de09c08e370f6d9970dbb6 upstream.
So far, sub part of mv_cesa_int was responsible of dequeuing complete
requests, then call the 'cleanup' operation on these reqs and call the
crypto api callback 'complete'. The problem is that the transformation
context 'ctx' is retrieved only once before the while loop. Which means
that the wrong 'cleanup' operation might be called on the wrong type of
cesa requests, it can lead to memory corruptions with this message:
marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, 5a5a5a5a/5a5a5a5a (bad dma)
This commit fixes the issue, by updating the transformation context for
each dequeued cesa request.

Currently, in mv_cesa_{md5,sha1,sha256}_init creq->state is initialized
before the call to mv_cesa_ahash_init. This is wrong because this
function fills creq with zero by using memset, so its 'state' that
contains the default DIGEST is overwritten. This commit fixes the issue
by initializing creq->state just after the call to mv_cesa_ahash_init.

commit 18f53fe0f30331e826b075709ed7b26b9283235e upstream.
commit 7a0adc83f34d ("ath10k: improve tx scheduling") is causing
severe throughput drop in multi client mode. This issue is originally
reported in veriwave setup with 50 clients with TCP downlink traffic.
While increasing number of clients, the average throughput drops
gradually. With 50 clients, the combined peak throughput is decreased
to 98 Mbps whereas reverting given commit restored it to 550 Mbps.
Processing txqs for every tx completion is causing overhead. Ideally for
management frame tx completion, pending txqs processing can be avoided.
The change partly reverts the commit "ath10k: improve tx scheduling".
Processing pending txqs after all skbs tx completion will yeild enough
room to burst tx frames.

commit e4fd726f21cdae0dc9cea6cbfcb7e27f21393f88 upstream.
In the wake tx queue path, we are not checking if the frame to be sent
takes management path or not. For eg. QOS null func frame coming here will
take the management path. Since we are not incrementing the descriptor
counter (num_pending_mgmt_tx) w.r.t tx management, on tx completion it is
possible to see negative values.
When the above counter reaches a negative value, we will not be sending a
probe response out.
if (is_presp &&
ar->hw_params.max_probe_resp_desc_thres < htt->num_pending_mgmt_tx)
For IPQ4019, max_probe_resp_desc_thres (u32) is 24 is compared against
num_pending_mgmt_tx (int) and the above condtions comes true if the counter
is negative and we drop the probe response.
To avoid this, check on the wake tx queue path as well for the tx path of
the frame and increment the appropriate counters
