fan speed
Fix for Thinkpad's with ECFW showing incorrect fan speed. Some models use
decimal instead of hexadecimal for the speed stored in the EC registers.
For example the rpm register will have 0x4200 instead of 0x1068, here
the actual RPM is "4200" in decimal.
Add a quirk to handle this.

Pull SoC fixes from Arnd Bergmann:
"Where the last set of fixes was mostly drivers, this time the
devicetree changes all come at once, targeting mostly the Rockchips,
Qualcomm and NXP platforms.
The Qualcomm bugfixes target the Snapdragon X Elite laptops,
specifically problems with PCIe and NVMe support to improve
reliability, and a boot regresion on msm8939.
Also for Snapdragon platforms, there are a number of correctness
changes in the several platform specific device drivers, but none of
these are as impactful.
On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants,
correcting individual entries in the devicetree that were incorrect
and causing the media, video, mmc and spi drivers to misbehave in
minor ways.
The Arm SCMI firmware driver gets fixes for a use-after-free bug and
for correctly parsing firmware information.
On the RISC-V side, there are three minor devicetree fixes for
starfive and sophgo, again addressing only minor mistakes. One device
driver patch fixes a problem with spurious interrupt handling"

Out-of-bounds access occurs if the fast device is expanded unexpectedly
before the first-time resume of the cache table. This happens because
expanding the fast device requires reloading the cache table for
cache_create to allocate new in-core data structures that fit the new
size, and the check in cache_preresume is not performed during the
first resume, leading to the issue.
Reproduce steps:
1. prepare component devices:
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct
2. load a cache table of 512 cache blocks, and deliberately expand the
fast device before resuming the cache, making the in-core data
structures inadequate.
dmsetup create cache --notable
dmsetup reload cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
dmsetup reload cdata --table "0 131072 linear /dev/sdc 8192"
dmsetup resume cdata
dmsetup resume cache
3. suspend the cache to write out the in-core dirty bitset and hint
array, leading to out-of-bounds access to the dirty bitset at offset
0x40:
dmsetup suspend cache

When shrinking the fast device, dm-cache iteratively searches for a
dirty bit among the cache blocks to be dropped, which is less efficient.
Use find_next_bit instead, as it is twice as fast as the iterative
approach with test_bit.

dm-cache checks the dirty bits of the cache blocks to be dropped when
shrinking the fast device, but an index bug in bitset iteration causes
out-of-bounds access.
Reproduce steps:
1. create a cache device of 1024 cache blocks (128 bytes dirty bitset)
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 131072 linear /dev/sdc 8192"

/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
2. shrink the fast device to 512 cache blocks, triggering out-of-bounds
access to the dirty bitset (offset 0x80)
dmsetup suspend cache
dmsetup reload cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup resume cdata

An unexpected WARN_ON from flush_work() may occur when cache creation
fails, caused by destroying the uninitialized delayed_work waker in the
error path of cache_create(). For example, the warning appears on the
superblock checksum error.
Reproduce steps:

dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc 262144"

When creating a cache device, the actual size of the cache origin might
be greater than the specified cache target length. In such case, the
number of origin blocks should match the cache target length, not the
full size of the origin device, since access beyond the cache target is
not possible. This issue occurs when reducing the origin device size
using lvm, as lvreduce preloads the new cache table before resuming the
cache origin, which can result in incorrect sizes for the discard bitset
and smq hotspot blocks.
Reproduce steps:
1. create a cache device consists of 4096 origin blocks
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct
dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
2. reduce the cache origin to 2048 oblocks, in lvreduce's approach
dmsetup reload corig --table "0 262144 linear /dev/sdc 262144"
dmsetup reload cache --table "0 262144 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
dmsetup suspend cache
dmsetup suspend corig
dmsetup suspend cdata
dmsetup suspend cmeta
dmsetup resume corig
dmsetup resume cdata
dmsetup resume cmeta
dmsetup resume cache
3. shutdown the cache, and check the number of discard blocks in
superblock. The value is expected to be 2048, but actually is 4096.
dmsetup remove cache corig cdata cmeta
dd if=/dev/sdc bs=1c count=8 skip=224 2>/dev/null | hexdump -e '1/8 "%u\n"'
Fix by correcting the origin_blocks initialization in cache_create and
removing the unused origin_sectors from struct cache_args accordingly.

If the user sets panic_on_error and doesn't set panic_on_corruption,
dm-verity should not panic on data mismatch. But, currently it panics,
because it treats data mismatch as I/O error.
This commit fixes the logic so that if there is data mismatch and
panic_on_corruption or restart_on_corruption is not selected, the system
won't restart or panic.

This was found by a static analyzer.
There may be a potential integer overflow issue in
unstripe_ctr(). uc->unstripe_offset and uc->unstripe_width are
defined as "sector_t"(uint64_t), while uc->unstripe,
uc->chunk_size and uc->stripes are all defined as "uint32_t".
The result of the calculation will be limited to "uint32_t"
without correct casting.
So, we recommend adding an extra cast to prevent potential
integer overflow.

Qualcomm driver fixes for v6.12
The Qualcomm EDAC driver's configuration of interrupts is made optional,
to avoid violating security constriants on X Elite platform .
The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE,
is corrected to handle the case where firmware successfully returns that
the interface isn't supported.
The GLINK driver and the PMIC GLINK interface is updated to handle
buffer allocation issues during initialization of the communication
channel.
Allocation error handling in the socinfo dirver is corrected, and then
the fix is corrected.

Some Alienware devices have a key that locks/unlocks the Meta key. This
key triggers a WMI event that should be ignored by the kernel, as it's
handled by internally the firmware.
There is no known way of changing this default behavior. The firmware
would lock/unlock the Meta key, regardless of how the event is handled.

Setting TPM_CHIP_FLAG_SUSPENDED in the end of tpm_pm_suspend() can be racy
according, as this leaves window for tpm_hwrng_read() to be called while
the operation is in progress. The recent bug report gives also evidence of
this behaviour.
Aadress this by locking the TPM chip before checking any chip->flags both
in tpm_pm_suspend() and tpm_hwrng_read(). Move TPM_CHIP_FLAG_SUSPENDED
check inside tpm_get_random() so that it will be always checked only when
the lock is reserved.

which causes the cleanup loop to terminate early and leaking the
first allocated interrupt.
- Handle a corner case in GIC-V4 versus a lazily mapped Virtual
Processing Element (VPE). If the VPE has not been mapped because the
guest has not yet emitted a mapping command, then the set_affinity()
callback returns an error code, which causes the vCPU management to
fail.
Return success in this case without touching the hardware. This will
be done later when the guest issues the mapping command.

Commit d469647bafd9 ("Input: simplify event handling logic") introduced
code that would set handler->events() method to either
input_handler_events_filter() or input_handler_events_default() or
input_handler_events_null(), depending on the kind of input handler
(a filter or a regular one) we are dealing with. Unfortunately this
breaks cases when we try to re-register the same filter (as is the case
with sysrq handler): after initial registration the handler will have 2
event handling methods defined, and will run afoul of the check in
input_handler_check_methods():
input: input_handler_check_methods: only one event processing method can be defined (sysrq)
sysrq: Failed to register input handler, error -22
Fix this by adding handle_events() method to input_handle structure and
setting it up when registering a new input handle according to event
handling methods defined in associated input_handler structure, thus
avoiding modifying the input_handler structure.

Pull cxl fixes from Ira Weiny:
"The bulk of these fixes center around an initialization order bug
reported by Gregory Price and some additional fall out from the
debugging effort.
In summary, cxl_acpi and cxl_mem race and previously worked because of
a bus_rescan_devices() while testing without modules built in.
Unfortunately with modules built in the rescan would fail due to the
cxl_port driver being registered late via the build order. Furthermore
it was found bus_rescan_devices() did not guarantee a probe barrier
which CXL was expecting. Additional fixes to cxl-test and decoder
allocation came along as they were found in this debugging effort.
The other fixes are pretty minor but one affects trace point data seen
by user space.
Summary:
- Fix crashes when running with cxl-test code
- Fix Trace DRAM Event Record field decodes
- Fix module/built in initialization order errors
- Fix use after free on decoder shutdowns

"The important one is a change to the way in which we handle protection

materialised shortly afterwards.

longstanding fpsimd register corruption issues that we're almost at
the bottom of resolving.

interrupted context and align our user-visible behaviour with that

The gpiolib debugfs interface exports a list of all gpio chips in a
system and the state of their pins.
The gpio chip sections are supposed to be separated by a newline
character, but a long-standing bug prevents the separator from
being included when output is generated in multiple sessions, making the
output inconsistent and hard to read.
Make sure to only suppress the newline separator at the beginning of the
file as intended.

Short circuiting TDR on jobs not started is an optimization which is not
required. On LNL we are facing an issue where jobs do not get scheduled
by the GuC if it misses a GGTT page update. When this occurs let the TDR
fire, toggle the scheduling which may get the job unstuck, and print a
warning message. If the TDR fires twice on job that hasn't started,
timeout the job.
v2:
- Add warning message (Paulo)
- Add fixes tag (Paulo)
- Timeout job which hasn't started after TDR firing twice
v3:
- Include local change
v4:
- Short circuit check_timeout on job not started
- use warn level rather than notice (Paulo)

On LNL without a mmio read before a GGTT invalidate the GuC can
incorrectly read the GGTT scratch page upon next access leading to jobs
not getting scheduled. A mmio read before a GGTT invalidate seems to fix
this. Since a GGTT invalidate is not a hot code path, blindly do a mmio
read before each GGTT invalidate.

Even if it's not critical, the avoidance of checking the error code
from devm_mutex_init() call today diminishes the point of using devm
variant of it. Tomorrow it may even leak something. Add the missed
check.

Fix an issue detected by the Smatch tool:
drivers/gpio/gpiolib-swnode.c:78 swnode_find_gpio() error:
uninitialized symbol 'ret'.
The issue occurs because the 'ret' variable may be used without
initialization if the for_each_gpio_property_name loop does not run.
This could lead to returning an undefined value, causing unpredictable
behavior.
Initialize 'ret' to 0 before the loop to ensure the function
returns an error code if no properties are parsed, maintaining proper
error handling.
