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.

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.

ARM: SoC fixes for 6.11, part 3
The bulk of the changes this time are for device tree files in the
rockchips platform, addressing correctness issues on individual
boards, plus one change in the rk356x SoC file to make it match
the binding.
The only other changes that came in are
- a CPU frequencey scaling fix for JH7110 (RISC-V)
- a build fix for the cznic hwrandom driver
- a fix for a deadlock in qualcomm uefi secure
application firmware driver

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.

Merge tag 'scmi-updates-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers
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: SoC fixes for 6.11, part 2
There is a fairly large number of bug fixes for Qualcomm platforms, most of them addressing issues with the devicetree files for the newly added Snapdragon X1 based laptops to make them more reliable. The Qualcomm driver changes address a few build-time issues as well as runtime problems in the tzmem and scm firmware, the USB Type-C driver, and the cmd-db and pmic_glink soc drivers.

If the __qcuefi pointer is not set, then in the original code, we would
hold onto the lock. That means that if we tried to set it later, then
it would cause a deadlock. Drop the lock on the error path. That's

Qualcomm driver fixes for v6.11
This corrects the tzmem virt-to-phys conversion, which caused issues for the uefisecapp implementation of EFI variable access. SDM670 is excluded from tzmem usage due to reported issues. The SCM get wait queue context call is corrected to be marked ATOMIC and some dead code in qseecom, following the tzmem conversion, is removed. The memory backing command DB is remapped writecombined, to avoid XPU violations when Linux runs without the Qualcomm hypervisor. Two compile fixes are added for pd-mapper, and the broken reference count is corrected, to make pd-mapper deal with remoteprocs going away. In pmic_glink a race condition where the client callbacks might be called before we returned the client handle is corrected. The broken conditions for when to signal that the firmware is going down is also corrected. In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the pdr callback, as this is being invoked in atomic context. Konrad's email address is updated in MAINTAINERS, and related mailmap entries are added. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmbMlmAVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FwZwP/iXn8Okj8Xsg0paofr9jwetFaGAr b6BGd09Ygm8xdNi9zNqLHBZFJQaKlX5Ah5iG0trX1ljDZvdK6JjDz5IUGxXY8T5l R0TW/h/kHiA0UdsQDiGiwK68r4k/9rCwHP14CFSFMSLbTyrX/fiVZy2+GyjJ4/CS 53Dn3swGVeGU4HOZzh9AN4GVtzQu4ECUUZp50StuRvuDqCdjaHbc3JWieTtEWcSt 1dJkacNi1yJi1XxHSW6o7jR7ogDxLvMz95x26zhramPBzbsfAAjrkiwNDMz4w2Cj P+TjGunlYAOUoqwx0r3ffawNqQg5IoQRSH5fe/39UjzAAXdZoBv81BiQYypkWAdz 9Iyc13oEkKXUViS9tad9Qba31Ajxdgs2k0T8+XkLoEiFy9CIx7TtTcAP7549wxUI 89U1LMMZN0iAnEtSmGIc/C7Pr5iap+0beVOJuIZ8tX2vPf2QP8rxe52gvNW39mD3 IQeLnmxrmTSB9wk/ObddGNfftzA4yEOsnzHddv4w9AVoUH9dsvLuv+Y7C7oALTU+ RRvHcuUjJ0NJp7xcK0iTR0iqCKg0Rs+VHTnvWxFaIDGH6QdUMMgdBHXWF/f5mR7K Jx19VHm2u4IyNLxE6tzC/048PM0qEFEQws1C+dXvtuaC38VX5PBIVWGHTeU4ctsN nfkPYQDcEo71FNI5 =Zo90 -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmbPiDsACgkQYKtH/8kJ Uifk1xAAzHhy/tsQXK0IPSSzvJZJN9NeTkkGad6Nt6nN+jMXf9c+vTtDcPFlKMlp hPgXLJ/lh3l6NkEZ+3oI11CL/s3XJEbJaXJ9sqG3E6CUzzO15yII4hd4IqZWIa6x +YxdOlAgoQ6LgumidlgeiwRMxBM51KY7kgJIjv3aNQR0EL1F8tgBOqWCpU7cf8nC dtAdMy7oaVQFLzW4vtSMipmp0ppr2Evgae/u7qAZuSBunFReeQWggIMI3+hAJvtb hInoo8DNksZPfkfLteBmMPO1eyh6ByL2c8PvsriCf+QOK8ADKTwON+6mIya6ubLI Azvvz9cBOuXFPhc5OJKG7ZaN1SLRbuhwN2bf//5H6s54/WZFW9/lKQtxq8zjpGW5 NHKUGoIk/DgyfLs/rEZhvSEXr3jQUCBDNyMAAY0xoPwfqXhPS9flV4FcZn4qiIRh bnW1O4a1xwAT5Dwwla62LnzGbYJiKZ6Xi/VJQqg0uZABGdtw0FtjvY/Z8KJCEzYL H7T4iu9u+K43SNL/TytBXqMkVZNYMzSncu6NkYFpI0G3Pzw+h5q+BjncODn0Y8tX b8ZP/ee84Mumwi8k5lDBllaMoP3I7fyowgFsq5vrE9zpxRiMGJFDf9pxALXJddzN jgm/qia9XIU9VZe+Vnq9O73IPjd5P44v/HgUTRcJAB+5aHcylAk= =pkFq -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-fixes-for-6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes Qualcomm driver fixes for v6.11 This corrects the tzmem virt-to-phys conversion, which caused issues for the uefisecapp implementation of EFI variable access.

video/aperture: optionally match the device in sysfb_disable()
In aperture_remove_conflicting_pci_devices(), we currently only
call sysfb_disable() on vga class devices. This leads to the
following problem when the pimary device is not VGA compatible:
1. A PCI device with a non-VGA class is the boot display
2. That device is probed first and it is not a VGA device so
sysfb_disable() is not called, but the device resources
are freed by aperture_detach_platform_device()
3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable()
4. NULL pointer dereference via sysfb_disable() since the resources
have already been freed by aperture_detach_platform_device() when
it was called by the other device.
Fix this by passing a device pointer to sysfb_disable() and checking
the device to determine if we should execute it or not.

v3: Move device check into the mutex

An endpoint can discover the minimum size, maximum size and alignment boundary for the Rx/Tx buffers by passing the function ID of the FFA_RXTX_MAP ABI as input in the FFA_FEATURES interface. The maximum size is an optional field and a value of 0 means that the partition manager or the hypervisor does not enforce a maximum size. Use the discovery mechanism and remove the hardcoded 4kB buffer size. If the discovery fails, it still defaults to 4kB.

Successful completion of both direct messaging function can be indicated through an invocation of FFA_YIELD or GGA_INTERRUPT by the callee. FFA_INTERRUPT indicates that the direct request was interrupted and must be resumed through the FFA_RUN interface which is already done in the driver. FFA_YIELD indicates that the receiver endpoint has transitioned to the blocked runtime state and must be resumed through the FFA_RUN interface. However, the way receiver endpoint gets unblocked is implementation defined. So, the driver just sleeps for 1 - 2ms and issues FFA_RUN. It can return to the caller with FFA_YIELD is the receiver endpoint is still blocked. Message-Id: <20240820-ffa_v1-2-v2-6-18c0c5f3c65e@arm.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> |

firmware: arm_ffa: Add support for FFA_MSG_SEND_DIRECT_{REQ,RESP}2
FFA_MSG_SEND_DIRECT_{REQ,RESP} supported only x3-x7 to pass implementation
defined values as part of the message. This may not be sufficient sometimes
and also it would be good to use all the registers supported by SMCCC v1.2
(x0-x17) for such register based communication.
Also another limitation with the FFA_MSG_SEND_DIRECT_{REQ,RESP} is the
ability to target a specific service within the partition based on it's
UUID.
In order to address both of the above limitation, FF-A v1.2 introduced
FFA_MSG_SEND_DIRECT_{REQ,RESP}2 which has the ability to target the
message to a specific service based on its UUID within a partition as
well as utilise all the available registers(x4-x17 specifically) for
the communication.
This change adds support for FFA_MSG_SEND_DIRECT_REQ2 and
FFA_MSG_SEND_DIRECT_RESP2.

We need to first check if the platform supports this new API using FFA_FEATURES so that we can fallback to the FFA_PARTITION_INFO_GET (which is mandatory) if FFA_PARTITION_INFO_GET_REGS is not implemented.
