SoC fixes for 7.2
There are only three devicetree fixes this time: one critical memory
corruption fix for Renesas and three minor corrections for Tegra.
The MAINTAINERS file is updated for a new maintainer of the CIX platform
and two address changes.
The rest is all driver fixes, mostly firmware:
- multiple runtime issues in ARM SCMI and FF-A firmware code, dealing
with error handling for corner cases in firmware.
- multiple fixes for reset drivers, dealing with individual platform
specific mistakes and more error handling
- minor build and runtime fixes for the Tegra SoC drivers

firmware: stratix10-svc: fix teardown order in remove to prevent race
In stratix10_svc_drv_remove(), stratix10_svc_async_exit() was called
before client devices were unregistered. This created a race window
where child devices could still be issuing service requests through
the async channels after the async infrastructure had already been
torn down.
Unregister client devices before tearing down the async threads and
channels to ensure all in-flight service calls drain before the
underlying infrastructure is destroyed.

firmware: stratix10-svc: handle NO_RESPONSE in async poll
Define INTEL_SIP_SMC_STATUS_NO_RESPONSE (0x3) and handle it in
stratix10_svc_async_poll() the same way as INTEL_SIP_SMC_STATUS_BUSY,
returning -EAGAIN so callers can retry instead of treating the poll as
a hard failure.
When the Secure Device Manager has not yet produced a response for an
asynchronous transaction, ATF is expected to return
INTEL_SIP_SMC_STATUS_NO_RESPONSE. Without this handling, the service
layer maps the status to -EINVAL and async clients cannot distinguish
"not ready yet" from a real error.

firmware: arm_scmi: Rate-limit queue-full warnings in IRQ context
The scmi_notify() function is called from interrupt context to queue
received notification events onto a per-protocol kfifo. When the kfifo
is full, it logs a warning via dev_warn() for every dropped event.
Under conditions where the platform sends a burst of SCMI notifications
faster than the deferred worker can drain the queue, this results in a
flood of dev_warn() calls from IRQ context. Each call acquires the
console lock and may execute blocking console writes, causing the CPU
to be held in interrupt context for an extended period and leading to
observable system stalls.
Fix this by switching to dev_warn_ratelimited() to limit the frequency
of log messages when the notification queue is full. This reduces
console overhead in interrupt context and prevents CPU stalls caused by
excessive logging, while still preserving diagnostic visibility.

firmware: arm_scmi: Use 64-bit division for clock rate rounding
SCMI clock range descriptors report rates as 64-bit values. When handling
a range clock, scmi_clock_determine_rate() rounds the requested rate up to
the next supported step using the SCMI RATE_STEP value.
The current code uses div64_ul() for this calculation. Since div64_ul()
takes an unsigned long divisor, the 64-bit RATE_STEP value can be truncated
on 32-bit builds. In the worst case, a non-zero 64-bit step can be narrowed
to zero before the division.
Store RATE_STEP in a u64, reject a malformed zero step, and use
DIV64_U64_ROUND_UP() so the divisor is handled as a 64-bit value.
This does not change behavior for valid firmware reporting a non-zero step
that fits in unsigned long.
Tested on Xunlong Orange Pi 5 Plus / RK3588 with SCMI over SMC. SCMI
clocks probed successfully before and after the change. SCMI-backed CPU
clocks were exercised through cpufreq-dt by switching each CPU policy
between its lowest and highest available OPP.

firmware: arm_ffa: Fix Endpoint Memory Access Descriptor offset calculation
Use the descriptor's `ep_mem_offset` to calculate the start of the endpoint
memory access array and to comply with the FF-A spec instead of defaulting
to `sizeof(struct ffa_mem_region)`.
This requires moving `ffa_mem_region_additional_setup()` earlier in the setup
flow.
Also, add sanity checks to ensure the calculated descriptor offsets do not
exceed `max_fragsize`.

firmware: arm_ffa: Fix out-of-bound writes in ffa_setup_and_transmit()
Sashiko (locally) reports multiple out-of-bound issues in
ffa_setup_and_transmit:
1) Writing ep_mem_access->reserved can write out of bounds for FFA
versions < 1.2 as ffa_emad_size_get() returns 16 bytes in that case
while reserved has an offset of 24.
Instead of zeroing fields, memset the struct to zero first based on
the FFA version.
2) Make sure there is enough size to write constituents.
While at it, convert the only sizeof() in the driver that uses a
type instead of variable.

firmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get()
ffa_partition_info_get() passes uuid_str directly to uuid_parse()
without a NULL check. When a caller passes NULL, uuid_parse() ->
__uuid_parse() -> uuid_is_valid() dereferences the pointer, causing
a kernel panic:
| Unable to handle kernel NULL pointer dereference at virtual address
| 0000000000000040
| pc : uuid_parse+0x40/0xac
| lr : ffa_partition_info_get+0x1c/0x94 [arm_ffa]
Add a NULL guard before uuid_parse() so a NULL argument returns
-ENODEV instead of crashing. Callers are expected to always supply
a valid partition UUID, so NULL is not a supported input.

remoteproc updates for v7.2
Add i.MX94 support to the i.MX remoteproc driver, covering the Cortex-M7 and Cortex-M33 Sync cores. This also fixes programming of non-zero System Manager CPU/LMM reset vectors. Move the remoteproc resource table definitions to a separate header, so they can be used by clients that do not otherwise depend on remoteproc. Switch the firmware resource handling over to the common iterator. Update the Xilinx R5F remoteproc driver to check the remote core state before attaching, drop a binding header dependency, and add firmware-name based auto boot support. Add Qualcomm Hawi ADSP/CDSP bindings, together with Shikra RPM bindings and CDSP, LPAICP, and MPSS PAS support. Fix a Qualcomm minidump leak, clean up PAS and WCSS reset handling, and make the user-visible Qualcomm naming consistent. Remove a duplicate STM32_RPROC Kconfig dependency and make i.MX remoteproc instances use the device node name so multiple processors can be distinguished in sysfs. -----BEGIN PGP SIGNATURE----- iQJCBAABCgAsFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmo2pWgOHGJqb3JuQGty eW8uc2UACgkQCx85Pw2ZrcUxqA//XXAZHUD0Hz7Qag+z38N5qSCk/U/Qg38lvRWB lNDZ2g7KqmwdJbzJr5wzG8hoTO84hs3/nRAzV+KnwOIJ5M4EyH0AF9aqXjaqvyC7 V10OYSt5eQQZPBCZ87D7lABVxeuXtc07ETcecx3/zLZSdPqHUa25E1V86EwqYNl1 50wXTjbzhqdCOxKHxxhBhLq1GdPZE4shfzkTATfhAOTInRHwsfUS2u08Wh31kcuX eGG3vAIWQKbLGtM+ZLy/GCNhT58pBtHixnMjCJOmv2c8HzPoQmkSZbf+/8L6fOYY 48XbRJG1PdlraWVpEXzjJBLO+jULJmAtqlptMXX30V/qAnxoLWyU22Vw86hcj5XU Cxb/O1YconxtAbzQvCcB94oSpGM5DXXyHiUk+Cwizv3q+SHaMIdTA51Atpf/ly5k /di1FqOKzVHYbFDYYxttXmXrpUVIRfFDMkONoZgLZiE1cRZXrbwHrqZFaBz7lvw/ m/tu1+VX3jGaVJpyA5uAflxVW29r+VCNZ2RLKDC0vLnnRAut5oMbWUtLJlXhD9Ad wvgMkNMXPCsSyuUQ3gBLqHP8TdBMQav5dNGy0LcLuRDLN82I+h/GfxFOqowArKdh iVNnogPUJhscsSdnyspqBMDZ+fexYw6jIknt3ALet+6MWJ2gxt7k4j8y3CoRL6GB 5okVSqM= =6cLo -----END PGP SIGNATURE----- Merge tag 'rproc-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: - Add i.MX94 support to the i.MX remoteproc driver, covering the Cortex-M7 and Cortex-M33 Sync cores.

soc: drivers for 7.2
There are a few added drivers, but mostly the normal maintenance to drivers
for firmware, memory controller and other soc specific hadware:
- The NXP QuickEngine gets modern MSI support, which allows some cleanups to
the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC implementations,
and flexiblity around power managedment for the serial-engine driver
as well as probing the LLCC driver using custom hardware descriptions
inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed, tegra,
broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces,
to update driver probing, object lifetimes and address minor bugs.

the unregistration of thermal governors (Rafael Wysocki)
- Fix critical temperature attribute removal handling in the generic
thermal zone hwmon support code and rework that code to register a
separate hwmon class device for each thermal zone (instead of using
one hwmon class device for all thermal zones of the same type) to
address thermal zone removal deadlocks (Rafael Wysocki)

devices associated with thermal zones (Rafael Wysocki)
- Pass WQ_UNBOUND when allocating the thermal workqueue (Marco
Crivellari)

Merge tag 'kernel-7.2-rc1.task_exec_state' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull task_exec_state updates from Christian Brauner:
"This introduces a new per-task task_exec_state structure and relocates
the dumpable mode and the user namespace captured at execve() from
mm_struct onto it. It stays attached to the task for its full
lifetime.
__ptrace_may_access() and several /proc owner and visibility checks
need to consult two pieces of state for any observable task, including
zombies that have already gone through exit_mm(): the dumpable mode
and the user namespace captured at execve(). Both live on mm_struct
today, which exit_mm() clears from the task long before the task is
reaped. A reader that races with do_exit() observes task->mm == NULL
and either fails the check or falls back to init_user_ns - which
denies legitimate access to non-dumpable zombies that were running in
a nested user namespace.
mm_struct loses ->user_ns and the dumpability bits in ->flags.
MMF_DUMPABLE_BITS is reserved so the MMF_DUMP_FILTER_* layout exposed
via /proc/<pid>/coredump_filter stays stable. task->user_dumpable and
its exit_mm() snapshot are removed.
task_exec_state is the privilege domain established by an execve().
Within a thread group it is shared via refcount; across thread groups
each task has its own:
- CLONE_VM siblings (thread-group members, io_uring workers)
refcount-share the parent's exec_state.
- Non-CLONE_VM clones (fork(), vfork() without CLONE_VM) allocate a
fresh exec_state inheriting the parent's dumpable mode and user_ns.
- execve() in the child allocates a fresh instance and installs it
under task_lock + exec_update_lock via task_exec_state_replace().
- Credential changes (setresuid, capset, ...) and
prctl(PR_SET_DUMPABLE) update dumpability on the current task's
exec_state, i.e., on the thread group's shared instance.
On top of this exec_mmap() no longer tears down the old mm while
holding exec_update_lock for writing and cred_guard_mutex. Neither
lock is needed for that: exec_update_lock only exists to make the mm
swap atomic with the later commit_creds() and all its readers operate
on the new mm; none looks at the detached old mm.
The cost was real: __mmput() runs exit_mmap() over the entire old
address space and can block in exit_aio() waiting for in-flight AIO,
so execve() of a large process blocked ptrace_attach() and every
exec_update_lock reader for the duration of the teardown.
The old mm is now stashed in bprm->old_mm and released from
setup_new_exec() after both locks are dropped, with a backstop in
free_bprm() for the error paths"
* tag 'kernel-7.2-rc1.task_exec_state' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
exec: free the old mm outside the exec locks
exec_state: relocate dumpable information
ptrace: add ptracer_access_allowed()

firmware: stratix10-svc: Add support to query Arm Trusted Firmware (ATF) version
Add entry in Stratix10 service layer that allow client to retrieve the ATF version at runtime, which is useful for system diagnostics, compatibility checks, and ensuring the correct secure firmware is in use. The change introduces: - A new service command definition in the Stratix10 service layer to initiate the ATF version query. - A corresponding macro definition in the header file to expose the command ID for use by other components. The service layer uses a Secure Monitor Call (SMC) to communicate with the ATF and retrieve the version string, which can then be logged or validated by client application.

firmware: stratix10-rsu: avoid blocking reboot_image sysfs when busy
Writes to the reboot_image sysfs attribute went through rsu_send_msg(),
which unconditionally takes priv->lock with mutex_lock(). If another RSU
operation is in flight (e.g. a DCMF status query from probe or a
concurrent sysfs read path), userspace writers get stuck in the kernel
waiting on the mutex instead of being told the device is busy.
Split rsu_send_msg() into an inner __rsu_send_msg_locked() helper that
performs the SMC transaction with the caller holding priv->lock, plus
two thin wrappers: rsu_send_msg() preserves the original blocking
behaviour for existing callers, and rsu_try_send_msg() uses
mutex_trylock() and returns -EBUSY immediately when the lock is held.
Use rsu_try_send_msg() from reboot_image_store() so the write returns
-EBUSY without blocking when an RSU operation is already running.
Userspace can retry on -EBUSY. No functional change for other sysfs
attributes.
This keeps blocking rsu_send_msg() for existing callers, add
rsu_try_send_msg() with -EBUSY only for reboot_image_store(). That
matches the original goal (avoid a second reboot_image write blocking
behind priv->lock) without changing sysfs behaviour for the other
attributes. The earlier idea of using mutex_trylock() in all of
rsu_send_msg() and returning -EAGAIN would have been harder to justify
for userspace (echo does not retry on that).
Tze Yee tested the patch on an Agilex SoC devkit.
[Test 1] Idle reboot_image write (success path)
Result:
# insmod stratix10-rsu.ko
# echo 0x01000000 > .../reboot_image
# echo "exit=$?"
exit=0
# ./rsu_client --log
VERSION: 0x00000202
STATE: 0x00000000
CURRENT IMAGE: 0x0000000001000000
FAIL IMAGE: 0x0000000000000000
ERROR LOC: 0x00000000
ERROR DETAILS: 0x00000000
RETRY COUNTER: 0x00000000
Operation completed
[Test 2] reboot_image while priv->lock is held (-EBUSY path)
To get a deterministic busy window without flooding the service layer,
add a local debug helper (module parameter debug_hold_lock_sec +
kthread that holds priv->lock for N seconds after probe).
Result:
# insmod stratix10-rsu.ko debug_hold_lock_sec=60
[ 121.220904] stratix10-rsu stratix10-rsu.0: TEST: RSU lock held for
60 s - try reboot_image now
# echo 0x01000000 > .../reboot_image
-sh: echo: write error: Device or resource busy
# echo "during hold: exit=$?"
during hold: exit=1
[ 183.268706] stratix10-rsu stratix10-rsu.0: TEST: RSU lock released
# echo 0x01000000 > .../reboot_image
# echo "after release: exit=$?"
after release: exit=0
Together, these results match the intended behaviour: reboot_image
fails fast with -EBUSY when the RSU mutex is already held, and
succeeds once the lock is available.

soc: fixes for 7.1, part 2
Following the previous set of fixes, this addresses another significant
number of small issues found in firmware drivers (tee, optee, qcomtee,
qcom ice, exynos acpm) drivers through various tools. This is about
error handling, resource leaks, concurrency and a use-after-free bug.
The fixes for the Qualcomm ICE driver also introduce interface changes
in the UFS and MMC drivers using it.
Outside of firmware drivers, there are a few fixes across the tree:
- Minor driver code mistakes in the Atmel EBI memory controller,
the i.MX soc ID driver and socfpga boot logic
- A defconfig change to avoid a boot time regression on multiple
qualcomm boards
- Device tree fixes for qualcomm, at91 and gemini, addressing
mostly minor configuration mistakes

Merge tag 'soc-fixes-7.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC fixes from Arnd Bergmann:
"Following the previous set of fixes, this addresses another
significant number of small issues found in firmware drivers (tee,
optee, qcomtee, qcom ice, exynos acpm) drivers through various tools.
This is about error handling, resource leaks, concurrency and a
use-after-free bug.
The fixes for the Qualcomm ICE driver also introduce interface changes
in the UFS and MMC drivers using it.
Outside of firmware drivers, there are a few fixes across the tree:
- Minor driver code mistakes in the Atmel EBI memory controller, the
i.MX soc ID driver and socfpga boot logic
- A defconfig change to avoid a boot time regression on multiple
qualcomm boards
- Device tree fixes for qualcomm, at91 and gemini, addressing mostly
minor configuration mistakes"

firmware: tegra: bpmp: Add support for multi-socket platforms
On multi-socket platforms each socket has its own BPMP that is registered with the kernel, so the existing single fixed "bpmp" debugfs directory name cannot accommodate more than one instance. Group the per-socket BPMP debugfs entries under a shared top-level /sys/kernel/debug/bpmp/ directory, with each socket's BPMP device under a "<numa-node-id>-bpmp" subdirectory: /sys/kernel/debug/bpmp/0-bpmp/... /sys/kernel/debug/bpmp/1-bpmp/... For a multi-socket platform, the root debugfs bpmp/ directory is created by the first BPMP device that is populated. For single-socket platforms, the existing directory structure is preserved.

Arm FF-A + SMCCC updates for v7.2
1. The FF-A core is moved onto the driver model by reverting the earlier
rootfs initcall change and registering the core as a platform driver with
a synthetic arm-ffa platform device. Enumerated FF-A devices are now
parented below the FF-A core device, and probing is deferred until pKVM
has completed its FF-A proxy initialisation.
2. The platform-driver conversion is also adjusted so systems without FF-A
support treat early unsupported transport/version discovery as a quiet
probe miss rather than a failed matched probe.
3. The register-based partition discovery path now honors the descriptor
size reported by FFA_PARTITION_INFO_GET_REGS. This keeps parsing aligned
for newer FF-A descriptor layouts while still copying only the fields the
driver understands.
4. Also included is an Arm SMCCC fix for the optional SOC_ID name call: the
name query now uses the SMC64 function ID required for returning eight
characters per register.

firmware: samsung: acpm: Add devm_acpm_get_by_phandle helper
Introduce devm_acpm_get_by_phandle() to standardize how consumer drivers acquire a handle to the ACPM IPC interface. Enforce the use of the "samsung,acpm-ipc" property name across the SoC and simplify the boilerplate code in client drivers. The first consumer of this helper is the Exynos ACPM Thermal Management Unit (TMU) driver. The TMU utilizes a hybrid management approach: direct register access from the Application Processor (AP) is restricted to the interrupt pending (INTPEND) registers for event identification. High-level functional tasks, such as sensor initialization, threshold programming, and temperature reads, are delegated to the ACPM firmware via this IPC interface.

firmware: samsung: acpm: Make acpm_ops const and access via pointer
Replace the embedded `struct acpm_ops` inside `struct acpm_handle` with a pointer to a `const struct acpm_ops`. Previously, the operations structure was embedded directly within the handle and populated dynamically at runtime via `acpm_setup_ops()`. This resulted in mutable function pointers and unnecessary per-instance memory overhead. By defining `exynos_acpm_driver_ops` statically as a `const` structure, the function pointers are now safely housed in the read-only `.rodata` section. This improves security by preventing function pointer overwrites, saves memory, and slightly reduces initialization overhead in `acpm_probe()`. Consequently, update all consumer drivers (clk, mfd) to access the operations via the new pointer indirection (`->ops->`). Finally, fix the previously empty kernel-doc description for the ops member to reflect its new pointer nature.

Rename the `dvfs_ops` and `pmic_ops` members of `struct acpm_ops` to `dvfs` and `pmic` respectively. Since these members are housed within the `acpm_ops` structure and utilize the `acpm_*_ops` types, the `_ops` suffix on the variable names creates unnecessary redundancy (e.g., `handle.ops.dvfs_ops`).
