arm64 fixes for -rc7
- Fix handling of SVE traps from userspace on preemptible kernels when
converting the saved floating point state into SVE state.
- Remove broken support for the SMCCCv1.3 "SVE discard hint"
optimisation.
- Disable SME support, as the current support code suffers from numerous
issues around signal delivery, ptrace access and context-switch which
can lead to user-visible corruption of the register state.

Pull arm64 fixes from Will Deacon:
"Here is a (hopefully) final round of arm64 fixes for 6.12 that address
some user-visible floating point register corruption. Both of the
Marks have been working on this for a couple of weeks and we've ended
up in a position where SVE is solid but SME still has enough pending
issues that the most pragmatic solution for the release and stable
backports is to disable the feature. Yes, it's a shame, but the
hardware is rare as hen's teeth at the moment and we're better off
getting back to a known good state before fixing it all properly.
We're also improving the selftests for 6.13 to help avoid merging
broken code in the future.
Anyway, the good news is that we're removing a lot more code than
we're adding.
Summary:
- Fix handling of SVE traps from userspace on preemptible kernels
when converting the saved floating point state into SVE state.
- Remove broken support for the SMCCCv1.3 "SVE discard hint"

arm64: smccc: Remove broken support for SMCCCv1.3 SVE discard hint
SMCCCv1.3 added a hint bit which callers can set in an SMCCC function ID
(AKA "FID") to indicate that it is acceptable for the SMCCC
implementation to discard SVE and/or SME state over a specific SMCCC
call. The kernel support for using this hint is broken and SMCCC calls
may clobber the SVE and/or SME state of arbitrary tasks, though FPSIMD
state is unaffected.
The kernel support is intended to use the hint when there is no SVE or
SME state to save, and to do this it checks whether TIF_FOREIGN_FPSTATE
is set or TIF_SVE is clear in assembly code:
| ldr <flags>, [<current_task>, #TSK_TI_FLAGS]
| tbnz <flags>, #TIF_FOREIGN_FPSTATE, 1f // Any live FP state?
| tbnz <flags>, #TIF_SVE, 2f // Does that state include SVE?
|
| 1: orr <fid>, <fid>, ARM_SMCCC_1_3_SVE_HINT
| 2:
| << SMCCC call using FID >>
This is not safe as-is:
(1) SMCCC calls can be made in a preemptible context and preemption can
result in TIF_FOREIGN_FPSTATE being set or cleared at arbitrary
points in time. Thus checking for TIF_FOREIGN_FPSTATE provides no
guarantee.
(2) TIF_FOREIGN_FPSTATE only indicates that the live FP/SVE/SME state in
the CPU does not belong to the current task, and does not indicate
that clobbering this state is acceptable.
When the live CPU state is clobbered it is necessary to update
fpsimd_last_state.st to ensure that a subsequent context switch will
reload FP/SVE/SME state from memory rather than consuming the
clobbered state. This and the SMCCC call itself must happen in a
critical section with preemption disabled to avoid races.
(3) Live SVE/SME state can exist with TIF_SVE clear (e.g. with only
TIF_SME set), and checking TIF_SVE alone is insufficient.
Remove the broken support for the SMCCCv1.3 SVE saving hint. This is
effectively a revert of commits:

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.

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.

Arm SCMI fixes for v6.12(part 2)
Couple of fixes to address slab-use-after-free in scmi_bus_notifier() via scmi_dev->name and possible incorrect clear channel transport operation on A2P channel if some sort of P2A only messages are initiated on A2P channel(occurs when stress tested passing /dev/random to the channel). Apart from this, there are fixes to address missing "arm" prefix in the recently added property max-rx-timeout-ms which was missed in the review but was identified when further additions to the same binding were getting reviewed. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmcjvPAACgkQAEG6vDF+ 4pg2mA/9GejbeYklmQLUl4EoEjz305mdorg29CCilJ7SvUachV7T7Rv2I/W1GCmB F1eEwQe+SZ2COOEoIzKKvmEi7z49Cqm5gJbVvm8RVoR4Mrl1kAR373ZoO8rCFYEc DMThkSJcPOPG976mf5Fy9tbCpTOrHSBh46afqid09+0r1u2/5VzLqo3uBVsoclGB j8OixOlGokjL4K8cUs9cXLEJ9CJOyTu+0Z5e9HLvh4xj5l5n4remrMl9XWYBWuCR PWUAAxdDUlmyDbrWsmeIyed/E8m0i/+O6SOupteGNd7NLMSKBYAfFw2XSYxz1wj3 yuF5hWxyU5a3icF+r2pGS00m6M8GbGF1yiY0U6tu4EAqfZTHdfsFh3X2ix+uFi0m NCg9LmRLtlyBfgpt+Tj+X9Gw9Xq8nNBkaaVV14iYl1K7My3+RxLis8yesc+vfWmh aoMnYr7fLKHUb+gVg6C6Ge1DOSDA6rg+JLQR/UG8Q1nKuIa0Yu/rrWKGammsd4CR VMg48qKGTzpknSEh99yHzlFqGABdAUvJhpGqXcpHt+b13fjG3YY72gjT+uoThrDo IWe5JFAFypR4P7bdfNkIWOFAH7Um7M86lanCd+LXsZ94CtZeO0CfF4d/nCB89DI2 TPXb0E6UOdZitXhWpN2BO4S9yxPQGPIypIP/I3cThA6I762aOvc= =jlhL -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmck6icACgkQYKtH/8kJ UifMMw/7BRDD3WeczzKlXY0MbnufnrVD2C/317Mx7OawcaInXALqfniMTjUIs3X/ 06Ix90y7deDsCnXx9BCvpyOTVYGpwD7rjwDfiwrD+6wDeLWLMSpb53VRlIFNT8tc F7uu4onUYH699Z/XkGRAoyZKhARE3+2zhFPLU6qoTuE6n6ImD6DzrEQBFwhQbH+L gCCyIXfsFg5ALmKxi8Tcy3DSMnJt/AkV8o1dioTcOhxcQMScTeDgNUnSjglizvcB Hca+l7cNxRFod9Ux95PqRH2ny4tzwNN2omX/AHRAeaScgPkpfcsAWYlKRXfhdroy cxwdVGGEp73QbO2e+hTg99lwUi2mIb5AjDrGAmNp9YZF/8rZQ2qIMIWhdg4ugneJ H5iZSe3NOQYDdo4hpO5q1kXQQQbECBVimjpcV4+vlxD8OZ6AQoCNrPV0oC3atV9A 49yZq/RmMZMYJUmEIFjAgLx0HuDmH/QjlSVZbqBDiWpzpOf4fW8B+DaKqQOUlIpP 1+w2nBiWvtKCpG5g4rNfF+fvDv0H3EEWKUSREF8EIHQ1sAQiXcQToSDbKDkeJVOG ty4NDAMMM2JCd0MoD9QWE9UCOAdZbHw0Ub3FCZ03GP1gDb+HTifwZSFDlQLY8MqZ /89kptiwBdMd1Taclraw/lANThpgITaiqJe2Mubuz8LEvZslK7k= =E7pD -----END PGP SIGNATURE----- Merge tag 'scmi-fixes-6.12-2' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into HEAD Arm SCMI fixes for v6.12(part 2) Couple of fixes to address slab-use-after-free in scmi_bus_notifier() via scmi_dev->name and possible incorrect clear channel transport operation on A2P channel if some sort of P2A only messages are initiated on A2P channel(occurs when stress tested passing /dev/random to the channel).

firmware: qcom: scm: Return -EOPNOTSUPP for unsupported SHM bridge enabling
When enabling SHM bridge, QTEE returns 0 and sets error 4 in result to
qcom_scm for unsupported platforms. Currently, tzmem interprets this as
an unknown error rather than recognizing it as an unsupported platform.
Error log:
[ 0.177224] qcom_scm firmware:scm: error (____ptrval____): Failed to enable the TrustZone memory allocator
[ 0.177244] qcom_scm firmware:scm: probe with driver qcom_scm failed with error 4
To address this, modify the function call qcom_scm_shm_bridge_enable()
to remap result to indicate an unsupported error. This way, tzmem will
correctly identify it as an unsupported platform case instead of
reporting it as an error.

firmware: arm_scmi: Reject clear channel request on A2P
The clear channel transport operation is supposed to be called exclusively on the P2A channel from the agent, since it relinquishes the ownership of the channel to the platform, after this latter has initiated some sort of P2A communication. Make sure that, if it is ever called on a A2P, is logged and ignored.

firmware: arm_scmi: Fix slab-use-after-free in scmi_bus_notifier()
The scmi_dev->name is released prematurely in __scmi_device_destroy(),
which causes slab-use-after-free when accessing scmi_dev->name in
scmi_bus_notifier(). So move the release of scmi_dev->name to
scmi_device_release() to avoid slab-use-after-free.

firmware: microchip: auto-update: fix poll_complete() to not report spurious timeout errors
fw_upload's poll_complete() is really intended for use with
asynchronous write() implementations - or at least those where the
write() loop may terminate without the kernel yet being aware of whether
or not the firmware upload has succeeded. For auto-update, write() is
only ever called once and will only return when uploading has completed,
be that by passing or failing. The core fw_upload code only calls
poll_complete() after the final call to write() has returned.
However, the poll_complete() implementation in the auto-update driver
was written to expect poll_complete() to be called from another context,
and it waits for a completion signalled from write(). Since
poll_complete() is actually called from the same context, after the
write() loop has terminated, wait_for_completion() never sees the
completion get signalled and always times out, causing programming to
always report a failing.
Since write() is full synchronous, and its return value will indicate
whether or not programming passed or failed, poll_complete() serves no
purpose and can be cut down to simply return FW_UPLOAD_ERR_NONE.

Arm SCMI fixes for v6.12
Couple of fixes to address the issues found and reported on Broadcom STB platforms following the recent refactor of all the SCMI transports as standalone drivers. One of the issue is that the effective timeout value is much less than the intended value due to the way mailbox messages are queues in the mailbox framework. Since we block or serialise the shmem access anyway, there is no point in utilizing mailbox queues. The issue is fixed with exclusive lock on the channel when sending the message. The other issues is actually non-issue for upstream, but the workaround is just changing the link order of the transport drivers which enables Broadcom STB platforms to run both upstream and custom downstream kernel without any device tree changes. So pushing this to help them test upstream seamlessly as it has no practical or theoretical impact for others. There is also a fix to address possible double freeing of the name string in scmi_debugfs_common_cleanup() when devm_add_action_or_reset() fails. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmcOalcACgkQAEG6vDF+ 4pj9LhAAmTLLEGbDAWSGsU/WTGGTcYexmFnDHmHWTNeY435P1wF44aTabA+9ZVBk LZSQWNpduuSyAeQwxCUq3FuPtq2DhHSMZT55fzG4Cbt3+2ujNMHX7dUJC4aEU3U5 1P6PrAhSfvCzUKzF6KVtO0mlBx5+Ar8hayR2owewQpX7hlQV4yzM6lhYvByiRrII LeVD5mmreBe8k4PfUMsLyaY0Bms005HStcbB1ArVkRe5hr3IQ99FQ4Zhp06qqLLY +iqHLSZekGW0HUbtZVYAxJ8IOtgA88iI8B+7TF5iq7/UqxNGzRdSSeI6lrxZk9Qr OmcjrTfp+aohQOj0Fep+hLBj2rAdzAmnLIZMa4seLdY5tgZtoz7schDeqW2We2Uu WELpLgwXzrxeTn/CGXVKGVbB6eunAY0Hjf7NLnqmQe7x/Wt5cRkqpmPJhbMZKu75 iE5nk1CooaN7tBhrZUhqnEFtlN627V/tdqc8klVqnfArz99JA9Ec9ixdopp33sji QXFwM/xe/GfhZE/3+YdvRb0fGVvoWhU+2JvSKmGax4jWQpWSpVR/mD/BwMEH5lDn 8xTG/Bd/J71sHoPAhORdJVVDexNOoNoPIDBi6J5h4DzEvD5juFo5+TnWrXvzxGFy OH8H2Ic2qRTc290qO9oqwyRXZVPmd/46nEzn2oMeil3qvVdrAw0= =NahH -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmcO0w8ACgkQYKtH/8kJ Uif23w//SLRjEL/ZLhH1NuovqXPgvb8fsibMMQRTfyitCBwsxbhYvdy0gGwtZCTq 5eSbXx2O+GOZSRUaDWoEPIJAIuzR5ASjrgUWzjqEVy8diY9X5GO9mbiqByyQnsp3 GJxiemODqhvbvnFBdcedZIn2eUyPapTAAdj9+CCCcxdd71czxbJOb8ek4pVFN3OO fj+iKm6mT7qW7MM/tYsebgP/4oVcA+4Sz+XMjToyJ29vXoA31tWcrumnrMcRGLcy s685Nv8mhDw9ZsMhNbTghSACBslzxo2oQoKSkd0MiP7LmMxbDj9Nx4U+KxAlbR4f 4ZOzfBVkLv/oGwYG+sVAYJEkh2M0V9EurlECTnLg9taq1/bGCEyFjqAZ15EaCRLS T5VcDaXspiYR3glEWc2Ccbjbw3TD9PTUqBYsS8/jSLj6XKtrw1CnGQe5F3i9HCPL gLoHtX5T0fM2qu35ADQT7Xx49nXY+IXLvZBVqiy1lcjhPRrNyV8UYi0xGoTPcu0D 6rukL3VREmrNOJ1kuFc+T6KgWzxPMHwP6Ojiq6+UwiAdlDFOc323RuOeStVjVs34 G5bUNhVKWxCIH29NSR7/ckvLNCDh2DLkfwXuTz4P+foi9dEf2EMRuBSKueAF9ywO IoBJhwCb5o7WfyX5jdGT0UluNvnMjLA9i4qAjLWc7ZDO1PQsjqE= =iRE2 -----END PGP SIGNATURE----- Merge tag 'scmi-fixes-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm SCMI fixes for v6.12 Couple of fixes to address the issues found and reported on Broadcom STB platforms following the recent refactor of all the SCMI transports as standalone drivers.

firmware: arm_ffa: Avoid string-fortify warning caused by memcpy()
Copying from a 144 byte structure arm_smccc_1_2_regs at an offset of 32
into an 112 byte struct ffa_send_direct_data2 causes a compile-time warning:
| In file included from drivers/firmware/arm_ffa/driver.c:25:

Fix it by not passing a plain buffer to memcpy() to avoid the overflow
warning.

firmware: arm_scmi: Queue in scmi layer for mailbox implementation
send_message() does not block in the MBOX implementation. This is
because the mailbox layer has its own queue. However, this confuses
the per xfer timeouts as they all start their timeout ticks in
parallel.
Consider a case where the xfer timeout is 30ms and a SCMI transaction
takes 25ms:
| 0ms: Message #0 is queued in mailbox layer and sent out, then sits
| at scmi_wait_for_message_response() with a timeout of 30ms
| 1ms: Message #1 is queued in mailbox layer but not sent out yet.
| Since send_message() doesn't block, it also sits at
| scmi_wait_for_message_response() with a timeout of 30ms
| ...
| 25ms: Message #0 is completed, txdone is called and message #1 is sent
| 31ms: Message #1 times out since the count started at 1ms. Even though
| it has only been inflight for 6ms.

firmware/sysfb: Disable sysfb for firmware buffers with unknown parent
The sysfb framebuffer handling only operates on graphics devices
that provide the system's firmware framebuffer. If that device is
not known, assume that any graphics device has been initialized by
firmware.
Fixes a problem on i915 where sysfb does not release the firmware
framebuffer after the native graphics driver loaded.

ALong with the usual shower of singleton patches, notable patch series in
this pull request are:
"Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
consistency to the APIs and behaviour of these two core allocation
functions. This also simplifies/enables Rustification.
"Some cleanups for shmem" from Baolin Wang. No functional changes - mode
code reuse, better function naming, logic simplifications.
"mm: some small page fault cleanups" from Josef Bacik. No functional
changes - code cleanups only.
"Various memory tiering fixes" from Zi Yan. A small fix and a little
cleanup.
"mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
simplifications and .text shrinkage.
"Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt. This
is a feature, it adds new feilds to /proc/vmstat such as
$ grep kstack /proc/vmstat
kstack_1k 3
kstack_2k 188
kstack_4k 11391
kstack_8k 243
kstack_16k 0
which tells us that 11391 processes used 4k of stack while none at all
used 16k. Useful for some system tuning things, but partivularly useful
for "the dynamic kernel stack project".
"kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
Teaches kmemleak to detect leaksage of percpu memory.
"mm: memcg: page counters optimizations" from Roman Gushchin. "3
independent small optimizations of page counters".
"mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
Hildenbrand. Improves PTE/PMD splitlock detection, makes powerpc/8xx work
correctly by design rather than by accident.
"mm: remove arch_make_page_accessible()" from David Hildenbrand. Some
folio conversions which make arch_make_page_accessible() unneeded.
"mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
Cleans up and fixes our handling of the resetting of the cgroup/process
peak-memory-use detector.
"Make core VMA operations internal and testable" from Lorenzo Stoakes.
Rationalizaion and encapsulation of the VMA manipulation APIs. With a
view to better enable testing of the VMA functions, even from a
userspace-only harness.
"mm: zswap: fixes for global shrinker" from Takero Funaki. Fix issues in
the zswap global shrinker, resulting in improved performance.
"mm: print the promo watermark in zoneinfo" from Kaiyang Zhao. Fill in
some missing info in /proc/zoneinfo.
"mm: replace follow_page() by folio_walk" from David Hildenbrand. Code
cleanups and rationalizations (conversion to folio_walk()) resulting in
the removal of follow_page().
"improving dynamic zswap shrinker protection scheme" from Nhat Pham. Some
tuning to improve zswap's dynamic shrinker. Significant reductions in
swapin and improvements in performance are shown.
"mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
Improvements to the new unaccepted memory feature,
"mm/mprotect: Fix dax puds" from Peter Xu. Implements mprotect on DAX
PUDs. This was missing, although nobody seems to have notied yet.
"Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
Cleanups and modest performance improvements for the maple tree library
code.
"memcg: further decouple v1 code from v2" from Shakeel Butt. Move more
cgroup v1 remnants away from the v2 memcg code.
"memcg: initiate deprecation of v1 features" from Shakeel Butt. Adds
various warnings telling users that memcg v1 features are deprecated.
"mm: swap: mTHP swap allocator base on swap cluster order" from Chris Li.
Greatly improves the success rate of the mTHP swap allocation.

soc: driver updates for 6.12
The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
The TPM event log table is a Linux specific construct, where the data produced by the GetEventLog() boot service is cached in memory, and passed on to the OS using an EFI configuration table. The use of EFI_LOADER_DATA here results in the region being left unreserved in the E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code off into the weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY instead, which is always treated as reserved by the E820 conversion logic.

Qualcomm driver updates for v6.12
Support is added for making SCM driver configure the system either for a full or minimal ramdump following a system crash. The ramdump mode is changed from being enable-only to enable/disable as requested. The QSEECOM uefisecapp interface is allow-listed on Surface Laptop 7 and Lenovo Thinkpad T14s, providing EFI variable access. The change to match the SMD RPM driver based on the SMD channel name is reverted, in favor of stepping back to OF-based matching, as a means to get module autoloading to work properly. AOSS, APR, ICE, OCMEM, PBS and SMP2P drivers has error handling cleaned up using scoped resources. Trace events are added to the BWMON and SMP2P drivers, for better insights into their operations. The X1E LLCC configuration data is updated based on recommended values. A number of platforms are added to the in-kernel PD-mapper. SocInfo driver is extended with IDs from SM7325, QCS8275 and QCS8300 families. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmbYs3AVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FjywP/1IDWiKrOrIBYc6ndmssYrQLzlRw SSt/Q0YjPKogxl4qwTjTQUmBI/1I+vOa7kf9i0/BNpuslnhJYW51r9bZrcI0n3PW P1Pm7J32WGOIauFU9XoGmqzdlPBCVZKcfeCV3n9xTvF0pAipQqz46+O5mVg77jVU L5MaVIr4guk/glBJTym97KOlkSSbBsSmheistxiBJUIkUlZqX3YwBQE0Cih1VYOn DcQy29EjTpxhbLqI5BqFN3iJqGaV3RS32hL9hM8nYlXth0u8ZBy/H9AEViEK8M1K YakDoRkGyihj0M7oFV405yJdSskEbTBlxAfX7LH7x37XocRpsFf+u/Ti8VWxLMnt VUciuWA8bg6LnhMK1tQKEGM+3Wp2NZDJStKtV+OnYkvWbKN9QwS4DyiWdPvJGsgJ j4qq4B3nF3JU8Pu8Ih59LtPPFTa9/jMkOkqmF7smNehji8gjzHmkAhw6fWPCE5+h p8EC/XrYvXCwkBwPWE5vopip8CIpl3bMPb5bbHYGb4NuY59ztht40EExYxnhQzoN 3ezg+J2jIEaG/HQiBcxt0NrjyLRzkWJVryRxigg1co8Alcmxh7B1UNshiWRI70MA P3Emjh8Snixnp7ZD5O5hyiJ4yahomsfuCoDjVL6Vk4AYjon4ZjZ8pgcGBLgB1gry Zvkj5b5vc+8VNHnd =hZ0b -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmbZvJUACgkQYKtH/8kJ Uice9w//SXO0VlWitafyNuWwwqZfWZY953j2sjAjPWC2OWLGgjTQPL2sDKaOnvWG FRl8dZmYRcaEb7C7NeWvs1QrUztvxKDXOCDKlmt82EotyBlH1vLFWJK5KJ3oO0sD 0kQLWDr/KS/QIooXT/PcoFJ0mkpMqYKWV+XLLi+NDQsScMZsGyhZiDdv+qwX3qBw 9lt/srB1VfgW8gBrOGAxmS/WDQ4wup7/KPNpaUTIdPR8JMNFgoMCVY03LkB+FCcM 4s/MeecFzHavshFnZqcWzppf1FNX70lcaWEcbbNopM/bekZICFjGWZGoi+tK/8fZ WFj3OWZwDGYtxkYjT9M/zvxEJK2xDLosIOICV1dm+OcUN6LAXwknHBuCGMMNDQI1 jOQjZBXn3A+aT/Amy5GpKV0ci4K/tTI6AfBGdlZJq9jsQOMfP8Cygsv6leRp3dpJ 06v2ifSWUTv8+ucwYn/Oz0rZDZAe8ucswybzQo0lyor4Qg8lTZJFIU6iNoT/ZCCZ wlNg7t1OfkGGr08SuiAhV6+c5/CK2WivxCfKfZjw8+iMLJXyjE57fnf2HaU9Yfwp iJrV1euITVkLjmyMCg2YJSyWVl8O43T+LBcqreZel2iDJOBgY84zfk5hB/2sLLXj bo3H9QHD7IlQ3yOafT8zuxtanw3cJfBId34afsYD8h9khVz8OmI= =6GV4 -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.12 Support is added for making SCM driver configure the system either for a full or minimal ramdump following a system crash.

Arm SCMI updates for v6.12
Few main features include:
1. SCMI transport as stand-alone drivers
Currently the SCMI transport layer is being built embedded into in
the core SCMI stack. Some of these transports, despite being currently
part of the main SCMI module, are indeed also registered with different
subsystems like optee or virtio, and actively probed also by those.
This leads to a few awkward and convoluted tricks to properly handle
such interactions at boot time in the SCMI stack.
This change adds the new logic to the core SCMI stack so that each
existing transport is transitioned to be a standi-alone driver. With
that all the probe deferral and awkward retries between the SCMI
core stack and the transports has been removed, since no more needed.
2. Support for obtaining transport descriptors from the devicetree
SCMI platform firmwares might have different designs depending on
the platform. Some of the transport descriptors rely on such design.
E.g. the maximum receive channel timeout value might vary depending
on the specific underlying hardware and firmware design choices.
This change adds support for max-rx-timeout-ms property to describe
the transport needs of a specific platform design. It will be extended
in the future to obtain other such hardware/firmware dependent
transport related descriptors.
3. NXP i.MX95 specific SCMI vendor protocol extensions
SCMI specification allows vendor or platform-specific extensions to
the interface. NXP i.MX95 System Manager(SM) that implements SCMI
extends the interface to implement couple of vendor/platform specific
protocol, namely:
a. Battery Backed Module(BBM) Protocol
This protocol is intended provide access to the battery-backed
module. This contains persistent storage (GPR), an RTC, and the
ON/OFF button. The protocol can also provide access to similar
functions implemented via external board components.
b. MISC Protocol for misc settings
This includes controls that are misc settings/actions that must
be exposed from the SM to agents. They are device specific and
are usually define to access bit fields in various mix block
control modules, IOMUX_GPR, and other GPR/CSR owned by the SM.
4. SCMI debug/tracking metrics
Since SCMI involves interaction with the entity(software, firmware
and/or hardware) providing services or features, it is quite useful
to track certain metrics(for pure debugging purposes) like how many
messages were sent or received, were there any failures, what kind
of failures, ..etc. This feature adds support for the same via debugfs.
Apart from these main features, there are some miscellaneous updates, fixes
and cleanups.

Arm SCMI updates for v6.12
Few main features include:
1. SCMI transport as stand-alone drivers
Currently the SCMI transport layer is being built embedded into in
the core SCMI stack. Some of these transports, despite being currently
part of the main SCMI module, are indeed also registered with different
subsystems like optee or virtio, and actively probed also by those.
This leads to a few awkward and convoluted tricks to properly handle
such interactions at boot time in the SCMI stack.
This change adds the new logic to the core SCMI stack so that each
existing transport is transitioned to be a standi-alone driver. With
that all the probe deferral and awkward retries between the SCMI
core stack and the transports has been removed, since no more needed.
2. Support for obtaining transport descriptors from the devicetree
SCMI platform firmwares might have different designs depending on
the platform. Some of the transport descriptors rely on such design.
E.g. the maximum receive channel timeout value might vary depending
on the specific underlying hardware and firmware design choices.
This change adds support for max-rx-timeout-ms property to describe
the transport needs of a specific platform design. It will be extended
in the future to obtain other such hardware/firmware dependent
transport related descriptors.
3. NXP i.MX95 specific SCMI vendor protocol extensions
SCMI specification allows vendor or platform-specific extensions to
the interface. NXP i.MX95 System Manager(SM) that implements SCMI
extends the interface to implement couple of vendor/platform specific
protocol, namely:
a. Battery Backed Module(BBM) Protocol
This protocol is intended provide access to the battery-backed
module. This contains persistent storage (GPR), an RTC, and the
ON/OFF button. The protocol can also provide access to similar
functions implemented via external board components.
b. MISC Protocol for misc settings
This includes controls that are misc settings/actions that must
be exposed from the SM to agents. They are device specific and
are usually define to access bit fields in various mix block
control modules, IOMUX_GPR, and other GPR/CSR owned by the SM.
4. SCMI debug/tracking metrics
Since SCMI involves interaction with the entity(software, firmware
and/or hardware) providing services or features, it is quite useful
to track certain metrics(for pure debugging purposes) like how many
messages were sent or received, were there any failures, what kind
of failures, ..etc. This feature adds support for the same via debugfs.
Apart from these main features, there are some miscellaneous updates, fixes
and cleanups.
