Instead of calling __scm_smc_call() recursively to make the
waitqueue-specific SMC calls, make them directly by populating the SMC
call arguments by hand and calling __scm_smc_do_quirk().
Motivating points for this change:
1. With the exception of get_wq_ctx(), the other two waitqueue-specific
SMC calls wq_wake_ack() and wq_resume() can return WAIT_SLEEP, and
this cycle of attempting to resume and sleeping can take place
several times. With recursive logic, this can potentially lead to
stack overflow.
2. If an SMC client call has received WAITQ_SLEEP, it must prevent other
fresh client calls from being made until it has reached completion
(success or error). Therefore, handle the waitqueue operations within
the mutex qcom_scm_lock.
Use a do-while loop to iteratively check the return values of
wq_resume() and wq_wake_ack() for WAITQ_SLEEP or WAITQ_WAKE.

Devices which cannot tolerate latencies in notification after a

This change adds APIs to provide a way for such device drivers

To allow for early notifications to be sent to the SSR clients the q6v5

change adds an API in the q6v5 IRQ layer to optionally register the SSR
subdevice, and registers the SSR subdevice in the PAS driver.

Adb client on device expects a blocking read from mhi. While mhi
is in suspend, it is returning with an error value. This is
causing the adb client to spawn every 1ms causing error code to
flood the serial logs. If mhi is in suspend and adb client tries
to poll for data, remove the read request from the list to block
the read.

Commit 4c22227e39 ("cfg80211: fix management registrations locking")
in 5.10.77, which is commit 09b1d5dc6ce1 ("cfg80211: fix management
registrations locking") upstream, moved the mgmt_registrations_lock out
of struct wireless_dev. This did not change the structure size, but
caused a CRC change in the structure pointer, which tripped the abi
checker.
So restore the variable, and comment that this is not used anymore. No
driver should ever be touching this so it is safe.
Note, using a __GENKSYMS__ hack would work, as the overall structure
size remains the same when this variable is removed, BUT the warning
that the field is gone is reported by libabigail correctly, which would
require a .xml update, so it's not worth it.

The management registrations locking was broken, the list was
locked for each wdev, but cfg80211_mgmt_registrations_update()
iterated it without holding all the correct spinlocks, causing
list corruption.
Rather than trying to fix it with fine-grained locking, just
move the lock to the wiphy/rdev (still need the list on each
wdev), we already need to hold the wdev lock to change it, so
there's no contention on the lock in any case. This trivially
fixes the bug since we hold one wdev's lock already, and now
will hold the lock that protects all lists.

If kgsl mem entries are being accessed in sysfs and if putting
back the mementry refcount triggers a free of the process private,
we have a mutex deadlock. Because freeing the process private triggers
removal of the sysfs directories from within a thread that is accessing
the sysfs files. Fix this by taking an extra refcount on the process
private and then putting it back in a deferred manner.
