Pull remoteproc updates from Bjorn Andersson:
 "Add a remoteproc driver and binding for AMD MicroBlaze/V soft cores
  executing from dual-port BRAM, with clock and reset control and
  support for firmware without a resource table.

  Introduce a generic Qualcomm PAS service with SCM and OP-TEE backends,
  and migrate the PAS, MSS, and WCNSS remoteproc drivers to it. Add Nord
  ADSP and CDSP support, Eliza CDSP support, Maili ADSP/CDSP bindings,
  and late-attach SoCCP support for Kaanapali, Hawi, Maili, and Glymur.
  Enable BAM-DMUX child devices for PAS modems and fix PAS memory
  protection, handover, shutdown, and resource lifetime handling.

  Harden remoteproc lifecycle handling by attaching asynchronously,
  stopping crashed processors, synchronizing crash work with removal,
  and forcing shutdown before device resources are released. Reallocate
  resources during attach recovery and fix several reference and
  error-path leaks.

  Add Xilinx R5 crash detection and move RPU start and stop sequencing
  into the platform firmware driver. Consolidate write-combining
  carveout mapping callbacks, use correct I/O-memory accessors, and
  share optional ELF resource-table handling across drivers.

  Convert the TI Wakeup M3 binding to DT schema, correct Qualcomm and
  generic remoteproc bindings, and harden resource-table iteration
  against signed-offset out-of-bounds accesses"

Pull char/misc/IIO/etc driver updates from Greg KH:
 "Here is the big set of char, misc, iio, counter, fpga, and other small
  driver subsystems for 7.3-rc1.

  Overall, due to some driver removals we only added a bit more code
  than removed, which was a nice change. Highlights in this merge
  request are:

   - Loads of IIO driver updates and additions

   - binder driver updates (more on that below...)

   - Removal of the SGI XP and GRU drivers as they are not used anymore
     and turn out to be pretty insecure overall

   - Removal of the obsolete ibmasm driver as it's not being used
     anymore

   - Coresight driver updates and additions

   - Mei driver udpates

   - Counter driver updates

   - FPGA driver updates

   - ICC driver updates

   - lots and lots of other tiny driver updates to resolve reported

When __efi_queue_work() times out it disables runtime services and
returns, but the kworker is still blocked inside firmware. If the
firmware eventually unblocks, efi_call_rts() would run its tail on an
efi_rts_work that the timed-out caller has long abandoned: signalling a
stale completion and clearing efi_runtime_lock_owner that may by then
belong to another caller.

If runtime services have been disabled by the time the call returns,
park the worker with efi_rts_park_worker() instead, so it never touches
efi_rts_work again or returns to the workqueue.

Three wrappers call firmware directly instead of going through
__efi_queue_work(), and none of them check whether runtime services are
still enabled: virt_efi_set_variable_nb(),
virt_efi_query_variable_info_nb() and virt_efi_reset_system(). Once a
hang has cleared EFI_RUNTIME_SERVICES - or efi_recover_from_page_fault()
has cleared it on a firmware page fault - these paths still enter the
(possibly wedged) firmware, e.g. an EFI pstore write through the
non-blocking SetVariable() variant, in violation of UEFI's
non-reentrancy rules. reset_system() is reachable too: efi_reboot()
only gates it on the static efi_rt_services_supported() mask, which does
not track the runtime disable.

Check efi_enabled(EFI_RUNTIME_SERVICES) in each before calling into
firmware. Test it after taking efi_runtime_lock rather than before: the
bit is only ever cleared at runtime while that lock is held, so checking
it under the lock avoids racing with a concurrent timeout that clears the
bit and drops the lock.

When an EFI runtime service hangs in firmware, the efi_rts_wq worker is
stuck inside the call and cannot be cancelled. __efi_queue_work() then
waits on the completion forever while holding efi_runtime_lock, so every
later EFI caller is wedged until reboot; the only symptom is a "workqueue
lockup" and tasks piling up on the semaphore.

Replace wait_for_completion() with wait_for_completion_timeout() bounded
by EFI_RTS_TIMEOUT (120 seconds). On timeout, clear EFI_RUNTIME_SERVICES
and return EFI_ABORTED so later callers fail fast at the entry check
instead of each paying another 120 seconds. The wedged worker is
intentionally leaked and keeps ownership of efi_rts_work.

A worker that only starts running after the timeout would otherwise
dereference efi_rts_work.args, now pointing into the caller's freed stack
frame, and hand stale pointers to firmware. Park it with
efi_rts_park_worker() at the entry of efi_call_rts() when runtime
services are already disabled, before it touches args or enters firmware.

Known limitation: a worker already inside firmware when the timeout fires
still holds efi_rts_args pointing into the caller's stack frame; if
firmware unblocks afterwards and writes the output buffers, they land in
reused memory. Firmware hung this long rarely recovers; a follow-up could
bounce the buffers through kmalloc.

Move the EFI_RUNTIME_SERVICES check to the top of __efi_queue_work() and
return directly, so a caller that finds runtime services disabled returns
without touching the shared efi_rts_work. No functional change.

This prepares for bounding the wait, where a timeout will clear
EFI_RUNTIME_SERVICES while the leaked worker still owns efi_rts_work; a
later caller must then bail out before reinitialising it.
