When we dropped the custom Linux GPIO translation it resulted that the
IRQ numbers changed slightly as well. Normally this would be fine
because everyone is expected to use controller relative GPIO numbers and
ACPI GpioIo/GpioInt resources. However, there is a certain set of
Intel_Strago based Chromebooks where i8042 keyboard controller IRQ
number is hardcoded be 182 (this is corrected with newer coreboot but
the older ones still have the hardcoded Linux IRQ number). Because of
this hardcoded IRQ number keyboard on those systems accidentally broke
again.
Fix this by iteratively associating IRQ descriptors to the chip irqdomain
so that there are no gaps on those systems. Other systems are not
affected.

If we get an invalid device configuration from a palm 3 type device, we
might incorrectly parse things, and we have the potential to crash in
"interesting" ways.
Fix this up by verifying the size of the configuration passed to us by
the device, and only if it is correct, will we handle it.
Note that this also fixes an information leak of slab data.

Firmware requires that the ttl value for an encapsulating ipv4 tunnel
header be included as an action field. Prior to the support of Geneve
tunnel encap (when ttl set was removed completely), ttl value was
extracted from the tunnel key. However, tests have shown that this can
still produce a ttl of 0.
Fix the issue by setting the namespace default value for each new tunnel.
Follow up patch for net-next will do a full route lookup.

Commit af503716ac14 ("i2c: core: report OF style module alias for devices
registered via OF") fixed how the I2C core reports the module alias when
devices are registered via OF.
But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its
OF device ID table, so if a Device Tree is using a different one, autoload
won't be working for the module (the matching works because the I2C device
ID table is used as a fallback).
So add compatible strings for each of the entries in the I2C device table.

The automatic update mechanism will trigger an update if the
info block CRCs are different between maxtouch configuration
file (maxtouch.cfg) and chip.
The driver compared the CRCs without retrieving the chip CRC,
resulting always in a failure and firmware flashing action
triggered. Fix this issue by retrieving the chip info block
CRC before the check.
Note that this solution has the benefit that by reading the
information block and the object table into a contiguous region
of memory, we can verify the checksum at probe time. This means
we make sure that we are indeed talking to a chip that supports
object protocol correctly.
Using this patch on a kevin chromebook, the touchscreen and

Commit b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl")
introduced a mechanism to mark some BOs as purgeable to allow the driver
to drop them under memory pressure. In order to implement this feature
we had to add a mechanism to mark BOs as currently used by a piece of
hardware which materialized through the ->usecnt counter.
Plane code is supposed to increment usecnt when it attaches a BO to a
plane and decrement it when it's done with this BO, which was done in
the ->prepare_fb() and ->cleanup_fb() hooks. The problem is, async page
flip logic does not go through the regular atomic update path, and
->prepare_fb() and ->cleanup_fb() are not called in this case.
Fix that by manually calling vc4_bo_{inc,dec}_usecnt() in the
async-page-flip path.
Note that all this should go away as soon as we get generic async page
flip support in the core, in the meantime, this fix should do the
trick.

Currently, the kernel protects access to the agent ID allocator on a per
port basis using a spinlock, so it is impossible for two apps/threads on
the same port to get the same TID, but it is entirely possible for two
threads on different ports to end up with the same TID.
As this can be confusing (regardless of it being legal according to the
IB Spec 1.3, C13-18.1.1, in section 13.4.6.4 - TransactionID usage),
and as the rdma-core user space API for /dev/umad devices implies unique
TIDs even across ports, make the TID an atomic type so that no two
allocations, regardless of port number, will be the same.

Commit 6b5e718cc138 ("dm bufio: relax alignment constraint on slab
cache") relaxed alignment on dm-bufio cache, however it may break
dm-crypt or dm-integrity.
dm-crypt and dm-integrity require that the size of bio vector entries
(bv_len) is aligned on its sector size. bv_offset doesn't have to be
aligned, but bv_len must be. XFS sends unaligned bios, but they do not
cross page boundary, so the requirement for aligned bv_len is met.
Commit 6b5e718cc138 made dm-bufio send unaligned bios that cross page
boundary, this could break dm-crypt and dm-integrity.
Reinstates the alignment. Note that misaligned entries only happen when
we use slab/slub debugging. Without debugging, the entries are always
aligned.

Unfortunately some DSDTs issue bogus i2c reads to non existing devices
resulting in -EREMOTEIO errors because the non existing device of course
does not ack.
This happens e.g. from the The Asus T100TA's _BIX method, the DSDT on
the T100TA defines 2 resources on the I2C1 bus:
Name (EHID, ResourceTemplate ()
{
I2cSerialBusV2 (0x005B, ControllerInitiated, 0x00061A80,
AddressingMode7Bit, "\\_SB.I2C1",
0x00, ResourceConsumer, , Exclusive,
)
})
OperationRegion (EHOR, GenericSerialBus, Zero, 0x0100)
Field (EHOR, BufferAcc, NoLock, Preserve)
{
Connection (EHID),
Offset (0x01),
AccessAs (BufferAcc, AttribBytes (0x10)),
ABCD, 8
}
Name (UMPC, ResourceTemplate ()
{
I2cSerialBusV2 (0x0066, ControllerInitiated, 0x00061A80,
AddressingMode7Bit, "\\_SB.I2C1",
0x00, ResourceConsumer, , Exclusive,
)
})
The _BIX method does a single read (on each BIX() call) from the EHID
device through the ABCD Field, only to completely ignore the result.
This read always fails as there is no i2c client at address 0x5b.
The _BIX method also does several reads from the UMPC device and actually
uses the results of those to provide battery information.
IIRC I've also seen some DSTDs which do an i2c read to detect if a device
is present, also leading to false positive errors being logged.
Esp. the _BIX use is problematic as the _BIX method gets called
periodically to monitor battery status.
This commit stops the logs from filling up with errors like these:

Jeremy Cline correctly points out in rhbz#1514836 that a device where the
QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship
with a different wifi/bt chipset in some configurations.
If that is the case then we are needlessly penalizing those other chipsets
with a reset-resume quirk, typically causing 0.4W extra power use because
this disables runtime-pm.
This commit moves the DMI table check to a btusb_check_needs_reset_resume()
helper (so that we can easily also call it for other chipsets) and calls
this new helper only for QCA_ROME chipsets for now.

Add support to specify platform specific transition_delay_us instead
of using the transition delay derived from PCC.
With commit 3d41386d556d (cpufreq: CPPC: Use transition_delay_us
depending transition_latency) we are setting transition_delay_us
directly and not applying the LATENCY_MULTIPLIER. Because of that,
on Qualcomm Centriq we can end up with a very high rate of frequency
change requests when using the schedutil governor (default
rate_limit_us=10 compared to an earlier value of 10000).
The PCC subspace describes the rate at which the platform can accept
commands on the CPPC's PCC channel. This includes read and write
command on the PCC channel that can be used for reasons other than
frequency transitions. Moreover the same PCC subspace can be used by
multiple freq domains and deriving transition_delay_us from it as we
do now can be sub-optimal.
Moreover if a platform does not use PCC for desired_perf register then
there is no way to compute the transition latency or the delay_us.
CPPC does not have a standard defined mechanism to get the transition
rate or the latency at the moment.
Given the above limitations, it is simpler to have a platform specific
transition_delay_us and rely on PCC derived value only if a platform
specific value is not available.

Pull powerpc fixes from Michael Ellerman:
"A bunch of fixes, mostly for existing code and going to stable.
Our memory hot-unplug path wasn't flushing the cache before removing
memory. That is a problem now that we are doing memory hotplug on bare
metal.
Three fixes for the NPU code that supports devices connected via
NVLink (ie. GPUs). The main one tweaks the TLB flush algorithm to
avoid soft lockups for large flushes.
A fix for our memory error handling where we would loop infinitely,
returning back to the bad access and hard lockup the CPU.
Fixes for the OPAL RTC driver, which wasn't handling some error cases
correctly.
A fix for a hardlockup in the powernv cpufreq driver.
And finally two fixes to our smp_send_stop(), required due to a recent
change to use it on shutdown.
Thanks to: Alistair Popple, Balbir Singh, Laurentiu Tudor, Mahesh
Salgaonkar, Mark Hairgrove, Nicholas Piggin, Rashmica Gupta, Shilpasri

Owing to a missing conditional, the result of rps_may_expire_flow() was
being ignored and filters were being removed even if we'd decided not to
expire them.

efx->type->filter_insert() returns an ID rather than the index that
efx->type->filter_async_insert() used to, which causes it to exceed
efx->type->max_rx_ip_filters on some EF10 configurations, leading to out-
of-bounds array writes.
So, in efx_filter_rfs_work(), convert this back into an index (which is
what the remove call in the expiry path expects, anyway).

When a CQ is shared by multiple QPs, c4iw_flush_hw_cq() needs to acquire
corresponding QP lock before moving the CQEs into its corresponding SW
queue and accessing the SQ contents for completing a WR.
Ignore CQEs if corresponding QP is already flushed.

This patch fixes a crash that happens due to access to an
uninitialized DM pointer within the MR object.
The change makes sure the DM pointer in the MR object is set to
NULL during a non-DM MR creation to prevent a false indication
that this MR is related to a DM in the dereg flow.

This patch adds a check in the ib_uverbs_rereg_mr flow to make
sure there's no attempt to rereg a device memory MR to regular MR.
In such case the command will fail with -EINVAL status.
