Arm SCMI/FF-A fixes for v7.2
Fix two runtime issues in the SCMI framework. Use full 64-bit division
when rounding range-based clock rates, avoiding divisor truncation and
a possible divide-by-zero on 32-bit systems. Rate-limit notification
queue-full warnings emitted from interrupt context to prevent printk
floods and prolonged system stalls during notification bursts. Also
correct a grammar error in the ARM_SCMI_POWER_CONTROL Kconfig help
text.
Fix the FF-A driver RX/TX buffer sizing logic to respect the maximum
buffer size advertised by firmware, while retaining compatibility with
older implementations that may reject PAGE_SIZE-rounded buffers.
Also fix a NULL pointer dereference in ffa_partition_info_get() by
rejecting NULL UUID strings before passing them to uuid_parse().

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.

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.

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.

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.

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`.

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.

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.

FFA_FEATURES reports the minimum size and alignment boundary required
for RXTX_MAP. In FF-A v1.2 and later it can also report a maximum buffer
size, with zero meaning that no maximum is enforced.
The driver only used the minimum value and then rounded it up to PAGE_SIZE
before invoking RXTX_MAP after commit 83210251fd70 ("firmware: arm_ffa:
Use the correct buffer size during RXTX_MAP"). On systems where PAGE_SIZE
is larger than the advertised minimum, this can exceed a non-zero maximum
reported by firmware. Older implementations do not advertise a maximum and
may also reject the rounded-up size.
Decode the maximum size and clamp the page-aligned minimum to it when it
is present. If no maximum is advertised and RXTX_MAP rejects the rounded
size with INVALID_PARAMETERS, retry with the advertised minimum size.
Record drv_info->rxtx_bufsz only after RXTX_MAP succeeds so it reflects
the size registered with firmware.
While there, also update RXTX_MAP_MIN_BUFSZ() to use FIELD_GET() for
consistency.

Pull SoC driver updates from Arnd Bergmann:
"There are a few added drivers, but mostly the normal maintenance to
drivers for firmware, memory controller and other soc specific
hardware:
- 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 flexibility around power management 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"

Pull thermal control updates from Rafael Wysocki:
"These add new hardware support (i.MX93 TMU, Amlogic T7, Intel Arrow
Lake, QCom Nord, Shikra and Hawi), fix issues in a number of places in
the thermal control core and drivers, clean up code and refactor it in
preparation for future changes:
- Rework the initialization and cleanup of thermal class cooling
devices to separate DT-based cooling device registration and
cooling device registration without DT (Daniel Lezcano, Ovidiu
Panait)
- Update the cooling device DT bindings to support 3-cell cooling
device representation, where the additional cell holds an ID to
select a cooling mechanism for devices that offer multiple cooling
mechanisms, and adjust the cooling device registration code
accordingly (Gaurav Kohli, Daniel Lezcano)
- Remove dead code from two functions in the thermal core and
simplify 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)
- Use attribute groups for adding temperature attributes to hwmon
class devices associated with thermal zones (Rafael Wysocki)
- Pass WQ_UNBOUND when allocating the thermal workqueue (Marco
Crivellari)
- Fix potential shift overflow in ptc_mmio_write() and improve error
handling in proc_thermal_ptc_add() in the int340x thermal control
driver (Aravind Anilraj)
- Use sysfs_emit() for cpumask printing in the Intel powerclamp
thermal driver (Yury Norov)
- Add Arrow Lake CPU models to the intel_tcc_cooling driver (Srinivas
Pandruvada)
- Add QCom Nord, Shikra and Hawi temperature sensor DT bindings
(Deepti Jaggi, Gaurav Kohli, Dipa Ramesh Mantre)
- Use devm_add_action_or_reset() for clock disable on the NVidia
soctherm and switch it to devm cooling device registration version
(Daniel Lezcano)
- Add the Amlogic T7 thermal sensor along with thermal calibration
data read from SMC calls (Ronald Claveau)
- Fix atomic temperature read in the QCom tsens driver to comply with
hardware documentation (Priyansh Jain)
- Add SpacemiT K1 thermal sensor support (Shuwei Wu)
- Add i.MX93 temperature sensor support and filter out the invalid
temperature (Jacky Bai)
- Enable by default the TMU (Thermal Monitoring Unit) on Exynos
platform (Krzysztof Kozlowski)
- Rework interrupt initialization in the Tsens driver and add the
optional wakeup source (Priyansh Jain)
- Fix typo in a comment in the TSens QCom driver (Jinseok Kim)
- Fix trailing whitespace and repeated word in the OF code, remove
quoted string splitting across lines from the iMX7 driver, and
remove a stray space from the thermal_trip_of_attr() macro
definition (Mayur Kumar)

dereferences by rejecting missing command arguments and replace
sscanf() with kstrtoint() or kstrtoul() in that code (Ovidiu
Panait, Samuel Moelius)"

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"
