platform/x86: thinkpad_acpi: Fix for ThinkPad's with ECFW showing incorrect 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.

soc: fixes for 6.12, part 2
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. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmcpR7oACgkQYKtH/8kJ Uic9dA/+NzeNald+ap++pYYmIx9FcV3q3aieN4j5NRgAwUS84bNXpARkDQAK8lx8 GFzH7VUe0YwKlh+70P73eaLqsRyYE37eUyvabwnxgO0QnI798MZfM5diDvAFm0LK kQKnNLx0qojt6HQTN3PVfOn+rcp2J5dgUV+ZAG9TEM3YKA0MY/bABRqaZtIZzSxg WwM+jqFh5+EugiioSlL6HCdAVk12wwEJkAInEEY1y/KaeQS9K8vzEOwk4FDeIf2a 3V+G7IVIBI4rbvrAs2ukW3OrRiGT+svINS5k7qkap13YZUUjENnJYGYNm6woTTyb INpBowLKr1gJ1Aluk8AELvpa+aX1BY9rkxP+vTG0HrZVdrPcPToFUBQA4qZgpu/i k0uWb20uN1b2Uor2XP2hcTxvzfKPlvnYHxLTMG89PxoVrMX+oEQoCrAP24YcSkPd srV0aU54MUHANXEnNco0txdElK+8L7ZCyB19KpVnqqshohDpQ+zkX15Hw9uQLwEc RbF99SrR9KFg3sY62Q7LgJOhQ3x6LjGhqPCjejIZ9DvEzndArKYnkkiJYdxxhqkB WN1LB/PmnKPAAh1lJdej6SPhiwCCpEFG3IyS/H1/lv7CR94LVode1J4dYTJmcZaq aownmb4W1zECgMGQS6YjhuAG1h7D0QtSmWBAuiC+H+T2QTRPtKI= =9YYG -----END PGP SIGNATURE----- Merge tag 'arm-fixes-6.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc 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.

dm cache: fix potential out-of-bounds access on the first resume
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

dm cache: optimize dirty bit checking with find_next_bit when resizing
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: fix out-of-bounds access to the dirty bitset when resizing
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"

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"

dm cache: correct the number of origin blocks to match the target length
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.

dm-verity: don't crash if panic_on_corruption is not selected
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.

dm-unstriped: cast an operand to sector_t to prevent potential uint32_t overflow
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. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmck/kgVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FqV8QAMEYiZp4KnS6QkT4h47ET/dl3AiY EIyUge41uXjJYO4rK2JpYWi2Y30CXXwb0MRuhfZyI47mU2xYqP30hLEliqZLQqU3 ulc4hmVyPeelRtpSX36UyZQWcaTcr0IyWnhnPSPoIr/WuyvFojBVucnAzHGFYHw6 0Wl0Uwg0vaoptAXnAxC671ggkbXeUuxR1sOMnVAzAL9sUgZMAjDHg+Yc/Oz0i7KZ 16OcOPFWhN+PegrIAPKx5J3X9PUsEoPqE83y3DdRVv62c58RU5tfhrhEIhmo3DVn ruTbrf1vV6cE1iWfGQIxyVt0WJGnY/dZqQjQxinZF0U9dlJl5+ke9ZTsaRxF0s0J wejMDOoqtRbNeotLxhQAp0KbPbcUHg8kkUrYMiTZLMh4eNIEBi4yLT8KhDT7IUgT SEP6jK4z482xpaTrDf5hDmnIMSfAO9fC50QiUMc8eNGL84XYIJgcYfi+LAP7TSiV wP6PI1moQcSvq034csy4AfHlsULxMdqzqh86N4DSdkoa/om2JRiYIXfTkZOteOEg GR4gPYigdBV8X4jj4XDiRbk+hbf+bbc6qet0HKvBPjYcKyvpH+SEVMsuxzAO8ybP RjP5pDrOSb7mLlx/q8RBUwyuVWk6gtDhL6tgvwfP+qu+dxTcHgRSqAi5BQfOWMvf 2K4QO3/0tYunyqaf =H31v -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmcoyr0ACgkQYKtH/8kJ UiebJA/+OwoABEZcspBT92CnlAaIgIITx0znuO9srUcaiNxOTrZH2+T6z+sKHvOV bfhj0JZyK0Qk6sxU9PoczIXb2Xc42lemkZwL6TfDjQlOI10mvfTOgnIFPldG1RIp FcFjI3Tb6SKqh9GxDm5qLdxFn8ZoGKTLtUpP3FuV6lQNpiS7jLJILSNFXbVVMnk/ U2HY76YQ8u2DPk5ZXmjrw49NRDvQ22ufwxJJctE0fvVyr+AUhTFBHH9h6fo3RxbC 4IMCmEfVLnJ+ye9CqB4ahkcbu4gwzzU0eRpMb7mZ2GhufuCjgfBYA4U2XZhdEv0w 9GenVlPr0Hs1dtpUBxvfNf0kJ2uyti4UGkW7gn8+m/sl73bMVIGPX72rxdk3vbir yztmdl3Nya0Nh9fPJxwP4BT6JsMshsz0POzvIOqeRTUw9yKD+wIQg9a+cwWWqdlu jNvBGprW7MS03uQWIWYTGkjqDsStZVJaFO//PHx+ZZ0eY/H2Lminf3GL2tsAYUtE pIVsS4NUcCygEELb7cEbi+S9EMkgQZPd71VAex9bjKNquBs60fSU1GZr3oOuHluv 2XI2O+FPwdTH+yAXzqRlCj5Rczum0joa9q2lHW7hs/h7AKVSNCfzj+0YjDFIhu2E BnS0nbwm5axYm7vsnfA4O4QkE6AtGlRpmVfiumLg/Vif8KsA3N8= =2qZ7 -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-fixes-for-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes 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 .

tpm: Lock TPM chip in tpm_pm_suspend() first
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.

mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify()
When the MM_WALK capability is enabled, memory that is mostly accessed by
a VM appears younger than it really is, therefore this memory will be less
likely to be evicted. Therefore, the presence of a running VM can
significantly increase swap-outs for non-VM memory, regressing the
performance for the rest of the system.
Fix this regression by always calling {ptep,pmdp}_clear_young_notify()
whenever we clear the young bits on PMDs/PTEs.

mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats
Patch series "mm: multi-gen LRU: Have secondary MMUs participate in
MM_WALK".
Today, the MM_WALK capability causes MGLRU to clear the young bit from
PMDs and PTEs during the page table walk before eviction, but MGLRU does
not call the clear_young() MMU notifier in this case. By not calling this
notifier, the MM walk takes less time/CPU, but it causes pages that are
accessed mostly through KVM / secondary MMUs to appear younger than they
should be.
We do call the clear_young() notifier today, but only when attempting to
evict the page, so we end up clearing young/accessed information less
frequently for secondary MMUs than for mm PTEs, and therefore they appear
younger and are less likely to be evicted. Therefore, memory that is
*not* being accessed mostly by KVM will be evicted *more* frequently,
worsening performance.
ChromeOS observed a tab-open latency regression when enabling MGLRU with a
setup that involved running a VM:
Tab-open latency histogram (ms)
Version p50 mean p95 p99 max
base 1315 1198 2347 3454 10319
mglru 2559 1311 7399 12060 43758
fix 1119 926 2470 4211 6947
This series replaces the final non-selftest patchs from this series[1],
which introduced a similar change (and a new MMU notifier) with KVM
optimizations. I'll send a separate series (to Sean and Paolo) for the
KVM optimizations.
This series also makes proactive reclaim with MGLRU possible for KVM
memory. I have verified that this functions correctly with the selftest
from [1], but given that that test is a KVM selftest, I'll send it with
the rest of the KVM optimizations later. Andrew, let me know if you'd
like to take the test now anyway.
[1]: https://lore.kernel.org/linux-mm/20240926013506.860253-18-jthoughton@google.com/
This patch (of 2):
The removed stats, MM_LEAF_OLD and MM_NONLEAF_TOTAL, are not very helpful
and become more complicated to properly compute when adding
test/clear_young() notifiers in MGLRU's mm walk.

Here are some small char/misc/iio fixes for 6.12-rc6 that resolves some
reported issues. Included in here are the following:
- small IIO driver fixes for many reported issues
- mei driver fix for a suddenly much reported issue for an "old"
issue.
- MAINTAINERS update for a developer who has moved companies and
forgot to update their old entry.

A single fix for posix CPU timers
When a thread is cloned, the posix CPU timers are not inherited. If the parent has a CPU timer armed the corresponding tick dependency in the tasks tick_dep_mask is set and copied to the new thread, which means the new thread and all decendants will prevent the system to go into full NOHZ operation.

A few scheduler fixes:
- Plug a race between pick_next_task_fair() and try_to_wake_up() where
both try to write to the same task, even though both paths hold a
runqueue lock, but obviously from different runqueues.
The problem is that the store to task::on_rq in __block_task() is
visible to try_to_wake_up() which assumes that the task is not queued.
Both sides then operate on the same task.
Cure it by rearranging __block_task() so the the store to task::on_rq is
the last operation on the task.
- Prevent a potential NULL pointer dereference in task_numa_work()
task_numa_work() iterates the VMAs of a process. A concurrent unmap of
the address space can result in a NULL pointer return from vma_next()
which is unchecked.
Add the missing NULL pointer check to prevent this.
- Operate on the correct scheduler policy in task_should_scx()
task_should_scx() returns true when a task should be handled by sched
EXT. It checks the tasks scheduling policy.
This fails when the check is done before a policy has been set.
Cure it by handing the policy into task_should_scx() so it operates
on the requested value.
- Add the missing handling of sched EXT in the delayed dequeue
mechanism. This was simply forgotten.

Two fixes for the interrupt subsystem:
- Fix an off-by-one error in the failure path of msi_domain_alloc(),
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.

modpost: fix input MODULE_DEVICE_TABLE() built for 64-bit on 32-bit host
When building a 64-bit kernel on a 32-bit build host, incorrect
input MODULE_ALIAS() entries may be generated.
For example, when compiling a 64-bit kernel with CONFIG_INPUT_MOUSEDEV=m
on a 64-bit build machine, you will get the correct output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*r*a*0,*1,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*r*a*0,*1,*18,*1C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*r*a*0,*1,*m*l*s*f*w*");
However, building the same kernel on a 32-bit machine results in
incorrect output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*130,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*16A,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*165,*r*a*0,*1,*18,*1C,*20,*21,*38,*3C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*130,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
A similar issue occurs with CONFIG_INPUT_JOYDEV=m. On a 64-bit build
machine, the output is:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c

When building a 64-bit kernel, BITS_PER_LONG is defined as 64. However,
on a 32-bit build machine, the constant 1L is a signed 32-bit value.
Left-shifting it beyond 32 bits causes wraparound, and shifting by 31
or 63 bits makes it a negative value.

modpost: fix acpi MODULE_DEVICE_TABLE built with mismatched endianness
When CONFIG_SATA_AHCI_PLATFORM=m, modpost outputs incorect acpi
MODULE_ALIAS() if the endianness of the target and the build machine
do not match.
When the endianness of the target kernel and the build machine match,
the output is correct:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:010601:*");
However, when building a little-endian kernel on a big-endian machine
(or vice versa), the output is incorrect:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:0601??:*");
The 'cls' and 'cls_msk' fields are 32-bit.
DEF_FIELD() must be used instead of DEF_FIELD_ADDR() to correctly handle
endianness of these 32-bit fields.
The check 'if (cls)' was unnecessary; it never became NULL, as it was
the pointer to 'symval' plus the offset to the 'cls' field.

Rust fixes for v6.12 (3nd)
Toolchain and infrastructure:
- Avoid build errors with old 'rustc's without LLVM patch version
(important since it impacts people that do not even enable Rust).
- Update LLVM version for 'HAVE_CFI_ICALL_NORMALIZE_INTEGERS' in
'depends on' condition (the fix was eventually backported rather than
land in LLVM 19).

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.
