Linus Torvalds 8e17b16a2c SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
 reworks and support for variants of the existing SoC.  While this remains
 Arm centric for the most part, the branch now also contains updates to
 risc-v and loongarch specific code in drivers/soc/.
 
 Notable changes include:
 
  - Support for the newly added Qualcomm Snapdragon variants
    (MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
    soc ID, rpmh, rpm, spm and powerdomain drivers.
 
  - Documentation for the somewhat controversial qcom,board-id
    properties that are required for booting a number of machines
 
  - A new SoC identification driver for the loongson-2 (loongarch)
    platform
 
  - memory controller updates for stm32, tegra, and renesas.
 
  - a new DT binding to better describe LPDDR2/3/4/5 chips in
    the memory controller subsystem
 
  - Updates for Tegra specific drivers across multiple subsystems,
    improving support for newer SoCs and better identification
 
  - Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
    TI, Mediatek and Marvell SoC drivers

Yang Yingliang cce616e012 tee: optee: fix possible memory leak in optee_register_device()
If device_register() returns error in optee_register_device(),
the name allocated by dev_set_name() need be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup(),
and optee_device is freed in optee_release_device().

Linus Torvalds 27bc50fc90 - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative
   reports (or any positive ones, come to that).
 
 - Also the Maple Tree from Liam R.  Howlett.  An overlapping range-based
   tree for vmas.  It it apparently slight more efficient in its own right,
   but is mainly targeted at enabling work to reduce mmap_lock contention.
 
   Liam has identified a number of other tree users in the kernel which
   could be beneficially onverted to mapletrees.
 
   Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
   (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com).
   This has yet to be addressed due to Liam's unfortunately timed
   vacation.  He is now back and we'll get this fixed up.
 
 - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.  It uses
   clang-generated instrumentation to detect used-unintialized bugs down to
   the single bit level.
 
   KMSAN keeps finding bugs.  New ones, as well as the legacy ones.
 
 - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
   memory into THPs.
 
 - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support
   file/shmem-backed pages.
 
 - userfaultfd updates from Axel Rasmussen
 
 - zsmalloc cleanups from Alexey Romanov
 
 - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure
 
 - Huang Ying adds enhancements to NUMA balancing memory tiering mode's
   page promotion, with a new way of detecting hot pages.
 
 - memcg updates from Shakeel Butt: charging optimizations and reduced
   memory consumption.
 
 - memcg cleanups from Kairui Song.

Linus Torvalds ff6862c23d ARM: driver updates for 6.1
The drivers branch for 6.1 is a bit larger than for most releases.  Most
 of the changes come from SoC maintainers for the drivers/soc subsystem:
 
  - A new driver for error handling on the NVIDIA Tegra
    'control backbone' bus.
 
  - A new driver for Qualcomm LLCC/DDR bandwidth measurement
 
  - New Rockchip rv1126 and rk3588 power domain drivers
 
  - DT binding updates for memory controllers, older Rockchip
    SoCs, various Mediatek devices, Qualcomm SCM firmware
 
  - Minor updates to Hisilicon LPC bus, the Allwinner SRAM
    driver, the Apple rtkit firmware driver, Tegra firmware
 
  - Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
    Tegra, Qualcomm, Broadcom, NXP, ...)
 
 There are also some separate subsystem with downstream maintainers that
 merge updates this way:
 
  - Various updates and new drivers in the memory controller
    subsystem for Mediatek and Broadcom SoCs
 
  - Small set of changes in preparation to add support for FF-A

Arnd Bergmann 387969b7ab Arm FF-A firmware driver updates for v6.1
Small set of changes in preparation to add support for FF-A v1.1
 specification later. It mainly contains:
 
 1. Splitting up ffa_ops into different categories namely information,
    message and memory. It helps to make info and memory operations
    independent from ffa_device so thata generic memory management
    module can use it without specific ffa_dev.

Merge tag 'ffa-updates-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers

Arm FF-A firmware driver updates for v6.1

Small set of changes in preparation to add support for FF-A v1.1
specification later. It mainly contains:

1. Splitting up ffa_ops into different categories namely information,
   message and memory. It helps to make info and memory operations
   independent from ffa_device so thata generic memory management
   module can use it without specific ffa_dev.
2. Adds support for querying FF-A features and use the same to detect
   the support for 64-bit operations.
3. Adds v1.1 get_partition_info support and use the same to set up
   32-bit execution mode flag automatically.
4. Adds pointer to the ffa_dev_ops in struct ffa_dev and drop
   ffa_dev_ops_get() which enables to drop ffa_ops in optee_ffa
   structure using ffa_dev->ops directly. Additionally ffa_dev_ops is
   renamed as ffa_ops.

Sudeep Holla 5b0c6328e4 firmware: arm_ffa: Split up ffa_ops into info, message and memory operations
In preparation to make memory operations accessible for a non
ffa_driver/device, it is better to split the ffa_ops into different
categories of operations: info, message and memory. The info and memory
are ffa_device independent and can be used without any associated
ffa_device from a non ffa_driver.

However, we don't export these info and memory APIs yet without the user.
The first users of these APIs can export them.

Except the message APIs, all other APIs are ffa_device independent and can
be used without any associated ffa_device from a non ffa_driver.

In order to reflect the same, just rename ffa_dev_ops as ffa_ops to
avoid any confusion or to keep it simple.

Sudeep Holla 8c3812c8f7 firmware: arm_ffa: Make memory apis ffa_device independent
There is a requirement to make memory APIs independent of the ffa_device.
One of the use-case is to have a common memory driver that manages the
memory for all the ffa_devices. That common memory driver won't be a
ffa_driver or won't have any ffa_device associated with it. So having
these memory APIs accessible without a ffa_device is needed and should
be possible as most of these are handled by the partition manager(SPM
or hypervisor).

Drop the ffa_device argument to the memory APIs and make them ffa_device
independent.

Now that the ffa_device structure holds the pointer to ffa_dev_ops,
there is no need to obtain the same through ffa_dev_ops_get().

Just use the ffa_dev->ops directly. Since the ffa_device itself carries
ffa_dev_ops now, there is no need to keep a copy in optee_ffa structure.

Drop ffa_ops in the optee_ffa structure as it is not needed anymore.

With special lengths supplied by user space, register_shm_helper() has
an integer overflow when calculating the number of pages covered by a
supplied user space memory region.

This causes internal_get_user_pages_fast() a helper function of

Linus Torvalds cc3c470ae4 ARM: driver changes for 5.19
There are minor updates to SoC specific drivers for chips by Rockchip,
 Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
 driver changes include:
 
 - Several conversions of DT bindings to yaml format.
 
 - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
 
 - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
   and support for more chips in the RPMh power domains and the soc-id.
 
 - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
 
 - Apple M1 gains support for the on-chip NVMe controller, making it
   possible to finally use the internal disks. This also includes SoC
   drivers for their RTKit IPC and for the SART DMA address filter.
 
 For other subsystems that merge their drivers through the SoC tree,
 we have
 
 - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
   SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
   now has a cache for firmware argument structures as an optimization,
   and SCMI now supports the 3.1 version of the specification.
 
 - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers
 
 - Memory controller updates for Tegra, and a few updates for other
   platforms.

These look to be leftover from an early edition of this driver. Userspace
does not need this information. Checking all users of this that I have
access to I have verified no one is using them.

They leak internal use flags out to userspace. Even more they are not
correct anymore after a45ea4efa3. Lets drop these flags before
someone does try to use them for something and they become ABI.

Jens Wiklander ed8faf6c8f optee: add OPTEE_SMC_CALL_WITH_RPC_ARG and OPTEE_SMC_CALL_WITH_REGD_ARG
Adds OPTEE_SMC_CALL_WITH_RPC_ARG and OPTEE_SMC_CALL_WITH_REGD_ARG where
the struct optee_msg_arg to be used for RPC is appended in the memory
following the normal argument struct optee_msg_arg. This is an
optimization to avoid caching the RPC argument struct while still
maintaining similar performance as if it was cached.

OPTEE_SMC_CALL_WITH_REGD_ARG optimized one step further by using a
registered shared memory object instead. It's in other aspects identical
to OPTEE_SMC_CALL_WITH_RPC_ARG.

The presence of OPTEE_SMC_CALL_WITH_RPC_ARG and
OPTEE_SMC_CALL_WITH_REGD_ARG is indicated by the new
OPTEE_SMC_SEC_CAP_RPC_ARG bit returned by
OPTEE_SMC_EXCHANGE_CAPABILITIES. OPTEE_SMC_EXCHANGE_CAPABILITIES also
reports the number of arguments that the RPC argument struct must have
room for.

OPTEE_SMC_CALL_WITH_RPC_ARG and OPTEE_SMC_CALL_WITH_ARG can be used
interleaved with difference that when OPTEE_SMC_CALL_WITH_RPC_ARG is
used the RPC argument struct to be used is the one appended to the
normal argument struct. The same is true for
OPTEE_SMC_CALL_WITH_REGD_ARG.

Linus Torvalds b4bc93bd76 ARM driver updates for 5.18
There are a few separately maintained driver subsystems that we merge through
 the SoC tree, notable changes are:
 
  - Memory controller updates, mainly for Tegra and Mediatek SoCs,
    and clarifications for the memory controller DT bindings
 
  - SCMI firmware interface updates, in particular a new transport based
    on OPTEE and support for atomic operations.
 
  - Cleanups to the TEE subsystem, refactoring its memory management
 
 For SoC specific drivers without a separate subsystem, changes include
 
  - Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
    Layerscape SoCs.
 
  - Driver support for Microchip SAMA5D29, Tesla FSD, Renesas RZ/G2L,
    and Qualcomm SM8450.
 
  - Better power management on Mediatek MT81xx, NXP i.MX8MQ
    and older NVIDIA Tegra chips

Pull ARM driver updates from Arnd Bergmann:
 "There are a few separately maintained driver subsystems that we merge
  through the SoC tree, notable changes are:

   - Memory controller updates, mainly for Tegra and Mediatek SoCs, and
     clarifications for the memory controller DT bindings

   - SCMI firmware interface updates, in particular a new transport
     based on OPTEE and support for atomic operations.

   - Cleanups to the TEE subsystem, refactoring its memory management

  For SoC specific drivers without a separate subsystem, changes include

   - Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
     Layerscape SoCs.

   - Driver support for Microchip SAMA5D29, Tesla FSD, Renesas RZ/G2L,
     and Qualcomm SM8450.

   - Better power management on Mediatek MT81xx, NXP i.MX8MQ and older
     NVIDIA Tegra chips"

tee_shm_alloc() is replaced by three new functions,

tee_shm_alloc_user_buf() - for user mode allocations, replacing passing
the flags TEE_SHM_MAPPED | TEE_SHM_DMA_BUF

tee_shm_alloc_kernel_buf() - for kernel mode allocations, slightly
optimized compared to using the flags TEE_SHM_MAPPED | TEE_SHM_DMA_BUF.

tee_shm_alloc_priv_buf() - primarily for TEE driver internal use.

This also makes the interface easier to use as we can get rid of the
somewhat hard to use flags parameter.

The TEE subsystem and the TEE drivers are updated to use the new
functions instead.

Jens Wiklander d88e0493a0 tee: simplify shm pool handling
Replaces the shared memory pool based on two pools with a single pool.
The alloc() function pointer in struct tee_shm_pool_ops gets another
parameter, align. This makes it possible to make less than page aligned
allocations from the optional reserved shared memory pool while still
making user space allocations page aligned. With in practice unchanged
behaviour using only a single pool for bookkeeping.

The allocation algorithm in the static OP-TEE shared memory pool is
changed from best-fit to first-fit since only the latter supports an
alignment parameter. The best-fit algorithm was previously the default
choice and not a conscious one.

The optee and amdtee drivers are updated as needed to work with this
changed pool handling.

This also removes OPTEE_SHM_NUM_PRIV_PAGES which becomes obsolete with
this change as the private pages can be mixed with the payload pages.

The OP-TEE driver changes minimum alignment for argument struct from 8
bytes to 512 bytes. A typical OP-TEE private shm allocation is 224 bytes
(argument struct with 6 parameters, needed for open session). So with an
alignment of 512 well waste a bit more than 50%. Before this we had a
single page reserved for this so worst case usage compared to that would
be 3 pages instead of 1 page. However, this worst case only occurs if
there is a high pressure from multiple threads on secure world. All in
all this should scale up and down better than fixed boundaries.

Jens Wiklander aceeafefff optee: use driver internal tee_context for some rpc
Adds a driver private tee_context by moving the tee_context in struct
optee_notif to struct optee. This tee_context was previously used when
doing internal calls to secure world to deliver notification.

The new driver internal tee_context is now also when allocating driver
private shared memory. This decouples the shared memory object from its
original tee_context. This is needed when the life time of such a memory
allocation outlives the client tee_context.

This patch fixes the problem described below:

The addition of a shutdown hook by commit f25889f931 ("optee: fix tee out
of memory failure seen during kexec reboot") introduced a kernel shutdown
regression that can be triggered after running the OP-TEE xtest suites.

Once the shutdown hook is called it is not possible to communicate any more
with the supplicant process because the system is not scheduling task any
longer. Thus if the optee driver shutdown path receives a supplicant RPC
