soc: fixes for 6.13
There are three small fixes for the soc tree:
- A devicetee fix for the Arm Juno reference machine, so allow more
interesting PCI configurations
- A build fix for SCMI firmware on the NXP i.MX platform
- A fix for a race condition in Arm FF-A firmware

efi/zboot: Limit compression options to GZIP and ZSTD
For historical reasons, the legacy decompressor code on various architectures supports 7 different compression types for the compressed kernel image. EFI zboot is not a compression library museum, and so the options can be limited to what is likely to be useful in practice: - GZIP is tried and tested, and is still one of the fastest at decompression time, although the compression ratio is not very high; moreover, Fedora is already shipping EFI zboot kernels for arm64 that use GZIP, and QEMU implements direct support for it when booting a kernel without firmware loaded; - ZSTD has a very high compression ratio (although not the highest), and is almost as fast as GZIP at decompression time. Reducing the number of options makes it less of a hassle for other consumers of the EFI zboot format (such as QEMU today, and kexec in the future) to support it transparently without having to carry 7 different decompression libraries.

firmware: arm_ffa: Fix the race around setting ffa_dev->properties
Currently, ffa_dev->properties is set after the ffa_device_register()
call return in ffa_setup_partitions(). This could potentially result in
a race where the partition's properties is accessed while probing
struct ffa_device before it is set.
Update the ffa_device_register() to receive ffa_partition_info so all
the data from the partition information received from the firmware can
be updated into the struct ffa_device before the calling device_register()
in ffa_device_register().

firmware: arm_scmi: Fix i.MX build dependency
The newly added SCMI vendor driver references functions in the protocol driver but needs a Kconfig dependency to ensure it can link, essentially the Kconfig dependency needs to be reversed to match the link time dependency: | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_write': | fsl_mqs.c:(.text+0x1aa): undefined reference to `scmi_imx_misc_ctrl_set' | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_read': | fsl_mqs.c:(.text+0x1ee): undefined reference to `scmi_imx_misc_ctrl_get' This however only works after changing the dependency in the SND_SOC_FSL_MQS driver as well, which uses 'select IMX_SCMI_MISC_DRV' to turn on a driver it depends on. This is generally a bad idea, so the best solution is to change that into a dependency. To allow the ASoC driver to keep building with the SCMI support, this needs to be an optional dependency that enforces the link-time dependency if IMX_SCMI_MISC_DRV is a loadable module but not depend on it if that is disabled.

Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1
Here is the "big and hairy" char/misc/iio and other small driver
subsystem updates for 6.13-rc1. Sorry for doing this at the end of the
merge window, conference and holiday travel got in the way on my side
(hence the 5am pull request emails...)
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc
drivers actually possible. I think this is the tipping point,
expect to see way more rust drivers going forward now that these
bindings are present. Next merge window hopefully we will have pci
and platform drivers working, which will fully enable almost all
driver subsystems to start accepting (or at least getting) rust
drivers. This is the end result of a lot of work from a lot of
people, congrats to all of them for getting this far, you've proved
many of us wrong in the best way possible, working code :)
- IIO driver updates, too many to list individually, that subsystem
keeps growing and growing...
- Interconnect driver updates
- nvmem driver updates
- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)
- binder driver updates and fixes
- loads of other small char/misc/etc driver updates and additions,
full details in the shortlog.
Note, there is a semi-hairy rust merge conflict when pulling this. The
resolution has been in linux-next for a while and can be seen here:
https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
All of these have been in linux-next for a while, with no other reported
issues other than that merge conflict.

The biggest change here is eliminating the awful idea that KVM had, of
essentially guessing which pfns are refcounted pages. The reason to
do so was that KVM needs to map both non-refcounted pages (for example
BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP VMAs that contain
refcounted pages. However, the result was security issues in the past,
and more recently the inability to map VM_IO and VM_PFNMAP memory
that _is_ backed by struct page but is not refcounted. In particular
this broke virtio-gpu blob resources (which directly map host graphics
buffers into the guest as "vram" for the virtio-gpu device) with the
amdgpu driver, because amdgpu allocates non-compound higher order pages
and the tail pages could not be mapped into KVM.
This requires adjusting all uses of struct page in the per-architecture
code, to always work on the pfn whenever possible. The large series that
did this, from David Stevens and Sean Christopherson, also cleaned up
substantially the set of functions that provided arch code with the
pfn for a host virtual addresses. The previous maze of twisty little
passages, all different, is replaced by five functions (__gfn_to_page,
__kvm_faultin_pfn, the non-__ versions of these two, and kvm_prefetch_pages)
saving almost 200 lines of code.
ARM:
* Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
* Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call
was introduced in PSCIv1.3 as a mechanism to request hibernation,
similar to the S4 state in ACPI
* Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
* PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
* Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
* Avoid emulated MMIO completion if userspace has requested synchronous
external abort injection
* Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests
LoongArch:
* Add iocsr and mmio bus simulation in kernel.
* Add in-kernel interrupt controller emulation.
* Add support for virtualization extensions to the eiointc irqchip.
PPC:
* Drop lingering and utterly obsolete references to PPC970 KVM, which was
removed 10 years ago.
* Fix incorrect documentation references to non-existing ioctls
RISC-V:
* Accelerate KVM RISC-V when running as a guest
* Perf support to collect KVM guest statistics from host side
s390:
* New selftests: more ucontrol selftests and CPU model sanity checks
* Support for the gen17 CPU model
* List registers supported by KVM_GET/SET_ONE_REG in the documentation
x86:
* Cleanup KVM's handling of Accessed and Dirty bits to dedup code, improve
documentation, harden against unexpected changes. Even if the hardware
A/D tracking is disabled, it is possible to use the hardware-defined A/D
bits to track if a PFN is Accessed and/or Dirty, and that removes a lot
of special cases.
* Elide TLB flushes when aging secondary PTEs, as has been done in x86's
primary MMU for over 10 years.
* Recover huge pages in-place in the TDP MMU when dirty page logging is
toggled off, instead of zapping them and waiting until the page is
re-accessed to create a huge mapping. This reduces vCPU jitter.
* Batch TLB flushes when dirty page logging is toggled off. This reduces
the time it takes to disable dirty logging by ~3x.
* Remove the shrinker that was (poorly) attempting to reclaim shadow page
tables in low-memory situations.
* Clean up and optimize KVM's handling of writes to MSR_IA32_APICBASE.
* Advertise CPUIDs for new instructions in Clearwater Forest
* Quirk KVM's misguided behavior of initialized certain feature MSRs to
their maximum supported feature set, which can result in KVM creating
invalid vCPU state. E.g. initializing PERF_CAPABILITIES to a non-zero
value results in the vCPU having invalid state if userspace hides PDCM
from the guest, which in turn can lead to save/restore failures.
* Fix KVM's handling of non-canonical checks for vCPUs that support LA57
to better follow the "architecture", in quotes because the actual
behavior is poorly documented. E.g. most MSR writes and descriptor
table loads ignore CR4.LA57 and operate purely on whether the CPU
supports LA57.
* Bypass the register cache when querying CPL from kvm_sched_out(), as
filling the cache from IRQ context is generally unsafe; harden the
cache accessors to try to prevent similar issues from occuring in the
future. The issue that triggered this change was already fixed in 6.12,
but was still kinda latent.
* Advertise AMD_IBPB_RET to userspace, and fix a related bug where KVM
over-advertises SPEC_CTRL when trying to support cross-vendor VMs.
* Minor cleanups
* Switch hugepage recovery thread to use vhost_task. These kthreads can
consume significant amounts of CPU time on behalf of a VM or in response
to how the VM behaves (for example how it accesses its memory); therefore
KVM tried to place the thread in the VM's cgroups and charge the CPU
time consumed by that work to the VM's container. However the kthreads
did not process SIGSTOP/SIGCONT, and therefore cgroups which had KVM
instances inside could not complete freezing. Fix this by replacing the
kthread with a PF_USER_WORKER thread, via the vhost_task abstraction.
Another 100+ lines removed, with generally better behavior too like

Pull kvm updates from Paolo Bonzini:
"The biggest change here is eliminating the awful idea that KVM had of
essentially guessing which pfns are refcounted pages.
The reason to do so was that KVM needs to map both non-refcounted
pages (for example BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP
VMAs that contain refcounted pages.
However, the result was security issues in the past, and more recently
the inability to map VM_IO and VM_PFNMAP memory that _is_ backed by
struct page but is not refcounted. In particular this broke virtio-gpu
blob resources (which directly map host graphics buffers into the
guest as "vram" for the virtio-gpu device) with the amdgpu driver,
because amdgpu allocates non-compound higher order pages and the tail
pages could not be mapped into KVM.
This requires adjusting all uses of struct page in the
per-architecture code, to always work on the pfn whenever possible.
The large series that did this, from David Stevens and Sean
Christopherson, also cleaned up substantially the set of functions
that provided arch code with the pfn for a host virtual addresses.
The previous maze of twisty little passages, all different, is
replaced by five functions (__gfn_to_page, __kvm_faultin_pfn, the
non-__ versions of these two, and kvm_prefetch_pages) saving almost
200 lines of code.
ARM:
- Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
- Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This
call was introduced in PSCIv1.3 as a mechanism to request
hibernation, similar to the S4 state in ACPI
- Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
- PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
- Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
- Avoid emulated MMIO completion if userspace has requested
synchronous external abort injection
- Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests
LoongArch:
- Add iocsr and mmio bus simulation in kernel.
- Add in-kernel interrupt controller emulation.
- Add support for virtualization extensions to the eiointc irqchip.
PPC:
- Drop lingering and utterly obsolete references to PPC970 KVM, which
was removed 10 years ago.
- Fix incorrect documentation references to non-existing ioctls
RISC-V:
- Accelerate KVM RISC-V when running as a guest
- Perf support to collect KVM guest statistics from host side
s390:
- New selftests: more ucontrol selftests and CPU model sanity checks
- Support for the gen17 CPU model
- List registers supported by KVM_GET/SET_ONE_REG in the
documentation
x86:
- Cleanup KVM's handling of Accessed and Dirty bits to dedup code,
improve documentation, harden against unexpected changes.
Even if the hardware A/D tracking is disabled, it is possible to
use the hardware-defined A/D bits to track if a PFN is Accessed
and/or Dirty, and that removes a lot of special cases.
- Elide TLB flushes when aging secondary PTEs, as has been done in
x86's primary MMU for over 10 years.
- Recover huge pages in-place in the TDP MMU when dirty page logging
is toggled off, instead of zapping them and waiting until the page
is re-accessed to create a huge mapping. This reduces vCPU jitter.
- Batch TLB flushes when dirty page logging is toggled off. This
reduces the time it takes to disable dirty logging by ~3x.
- Remove the shrinker that was (poorly) attempting to reclaim shadow
page tables in low-memory situations.
- Clean up and optimize KVM's handling of writes to
MSR_IA32_APICBASE.
- Advertise CPUIDs for new instructions in Clearwater Forest
- Quirk KVM's misguided behavior of initialized certain feature MSRs
to their maximum supported feature set, which can result in KVM
creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to
a non-zero value results in the vCPU having invalid state if
userspace hides PDCM from the guest, which in turn can lead to
save/restore failures.
- Fix KVM's handling of non-canonical checks for vCPUs that support
LA57 to better follow the "architecture", in quotes because the
actual behavior is poorly documented. E.g. most MSR writes and
descriptor table loads ignore CR4.LA57 and operate purely on
whether the CPU supports LA57.
- Bypass the register cache when querying CPL from kvm_sched_out(),
as filling the cache from IRQ context is generally unsafe; harden
the cache accessors to try to prevent similar issues from occuring
in the future. The issue that triggered this change was already
fixed in 6.12, but was still kinda latent.
- Advertise AMD_IBPB_RET to userspace, and fix a related bug where
KVM over-advertises SPEC_CTRL when trying to support cross-vendor
VMs.
- Minor cleanups
- Switch hugepage recovery thread to use vhost_task.
These kthreads can consume significant amounts of CPU time on
behalf of a VM or in response to how the VM behaves (for example
how it accesses its memory); therefore KVM tried to place the
thread in the VM's cgroups and charge the CPU time consumed by that
work to the VM's container.
However the kthreads did not process SIGSTOP/SIGCONT, and therefore
cgroups which had KVM instances inside could not complete freezing.
Fix this by replacing the kthread with a PF_USER_WORKER thread, via
the vhost_task abstraction. Another 100+ lines removed, with
generally better behavior too like having these threads properly
parented in the process tree.
- Revert a workaround for an old CPU erratum (Nehalem/Westmere) that
didn't really work; there was really nothing to work around anyway:
the broken patch was meant to fix nested virtualization, but the
PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the
erratum.
- Fix 6.12 regression where CONFIG_KVM will be built as a module even
if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is
'y'.
x86 selftests:
- x86 selftests can now use AVX.

- Use rST internal links

set of supported features for additional SoCs in the QSEECOM, LLCC
and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip
sparx5 and amlogic reset drivers to support additional chips,
plus a few minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot

efi: Fix memory leak in efivar_ssdt_load
When we load SSDT from efi variable (specified with efivar_ssdt=<var> boot command line argument) a name for the variable is allocated dynamically because we traverse all EFI variables. Unlike ACPI table data, which is later used by ACPI engine, the name is no longer needed once traverse is complete -- don't forget to free this memory. Same time we silently ignore any errors happened here let's print a message if something went wrong (but do not exit since this is not a critical error and the system should continue to boot). Also while here -- add a note why we keep SSDT table on success. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

efi/libstub: Fix command line fallback handling when loading files
CONFIG_CMDLINE, when set, is supposed to serve either as a fallback when no command line is provided by the bootloader, or to be taken into account unconditionally, depending on the configured options. The initrd and dtb loader ignores CONFIG_CMDLINE in either case, and only takes the EFI firmware provided load options into account. This means that configuring the kernel with initrd= or dtb= on the built-in command line does not produce the expected result. Fix this by doing a separate pass over the built-in command line when dealing with initrd= or dtb= options. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

efi/libstub: Parse builtin command line after bootloader provided one
When CONFIG_CMDLINE_EXTEND is set, the core kernel command line handling logic appends CONFIG_CMDLINE to the bootloader provided command line. The EFI stub does the opposite, and parses the builtin one first. The usual behavior of command line options is that the last one takes precedence if it appears multiple times, unless there is a meaningful way to combine them. In either case, parsing the builtin command line first while the core kernel does it in the opposite order is likely to produce inconsistent results in such cases. Therefore, switch the order in the stub to match the core kernel. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

efi/memattr: Ignore table if the size is clearly bogus
There are reports [0] of cases where a corrupt EFI Memory Attributes Table leads to out of memory issues at boot because the descriptor size and entry count in the table header are still used to reserve the entire table in memory, even though the resulting region is gigabytes in size. Given that the EFI Memory Attributes Table is supposed to carry up to 3 entries for each EfiRuntimeServicesCode region in the EFI memory map, and given that there is no reason for the descriptor size used in the table to exceed the one used in the EFI memory map, 3x the size of the entire EFI memory map is a reasonable upper bound for the size of this table. This means that sizes exceeding that are highly likely to be based on corrupted data, and the table should just be ignored instead.

itself, and likely points into the caller's stack.
cmdline refers to the pool allocation that should be freed when cleaning
up after a failure, so pass this instead to free_pool().

KVM/arm64 changes for 6.13, part #1
- Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
- Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call
was introduced in PSCIv1.3 as a mechanism to request hibernation,
similar to the S4 state in ACPI
- Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
- PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
- Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
- Avoid emulated MMIO completion if userspace has requested synchronous
external abort injection
- Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests

A few more Qualcomm driver updates for v6.13
Make the Adreno driver invoke the SMMU aperture setup firmware function, which is required to allow the GPU to manage per-process page tables in some firmware versions - as an example Rb3Gen2 has no GPU without this. Add X1E Devkit to the list of devices that has functional EFI variable access through the uefisecapp. Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver, as this only applies to a single platform, and introduce support for QCS8300, QCS615, SAR2130P, and SAR1130P.

Arm SCMI updates for v6.13
Just couple of main additions:
1. Support for variable I/O width within ARM SCMI shared memory area.
Some shared memory areas might only support a certain access width,
such as 32-bit, which memcpy_{from,to}_io() does not adhere to at least
on ARM64 by making both 8-bit and 64-bit accesses to such memory.
This support updates the shmem layer to support reading from and
writing to such shared memory area using the specified I/O width
in the Device Tree. The various transport layers making use of the
shmem.c code are updated accordingly to pass the I/O accessors that
they store. The device tree bindings are also updated for the same.
2. Extension of SCMI transport bindings to add more properties
SCMI transports are characterized by a number of properties. The
values assumed by some of them tightly depend on the choices taken at
design time and on the overall archiecture of the specific platform:
things like timeouts, maximum message size and number of in-flight
messages are closely tied to the architecture of the platform like
number of SCMI agents on the system, physical memory available to the
SCMI platform and so on. Such details are not discoverable as they are
outside the scope of the SCMI protocol specification.
Currently such properties are simple default values defined at build
time, but the increasing number and variety of platforms using SCMI
with a wide range of designs has increased the need to have a way to
describe such properties across all these platforms.
Apart from the above two, there is one NULL pointer dereference fix for
very age old SCPI protocol driver which seems to be still in use on few
platforms.

firmware: qcom: scm: Introduce CP_SMMU_APERTURE_ID
The QCOM_SCM_SVC_MP service provides QCOM_SCM_MP_CP_SMMU_APERTURE_ID, which is used to trigger the mapping of register banks into the SMMU context for per-processes page tables to function (in case this isn't statically setup by firmware). This is necessary on e.g. QCS6490 Rb3Gen2, in order to avoid "CP | AHB bus error"-errors from the GPU. Introduce a function to allow the msm driver to invoke this call.

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"
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"

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 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 .

arm64 fixes for -rc6
- Fix handling of POR_EL0 during signal delivery so that pushing the
signal context doesn't fail based on the pkey configuration of the
interrupted context and align our user-visible behaviour with that of
x86.
- Fix a bogus pointer being passed to the CPU hotplug code from the
Arm SDEI driver.
- Re-enable software tag-based KASAN with GCC by using an alternative
implementation of '__no_sanitize_address'.

Pull arm64 fixes from Will Deacon:
"The important one is a change to the way in which we handle protection
keys around signal delivery so that we're more closely aligned with
the x86 behaviour, however there is also a revert of the previous fix
to disable software tag-based KASAN with GCC, since a workaround
materialised shortly afterwards.
I'd love to say we're done with 6.12, but we're aware of some
longstanding fpsimd register corruption issues that we're almost at
the bottom of resolving.
Summary:
- Fix handling of POR_EL0 during signal delivery so that pushing the
signal context doesn't fail based on the pkey configuration of the
interrupted context and align our user-visible behaviour with that

- Fix a bogus pointer being passed to the CPU hotplug code from the

arm64: Use SYSTEM_OFF2 PSCI call to power off for hibernate
The PSCI v1.3 specification adds support for a SYSTEM_OFF2 function
which is analogous to ACPI S4 state. This will allow hosting
environments to determine that a guest is hibernated rather than just
powered off, and handle that state appropriately on subsequent launches.
