Don't map DDR memory as strongly ordered because it makes the memory
controller sad. All we really care about is the cache characteristics
and write-combine is the same as far as those are concerned.

Commit ef5440e7b8 ("msm: kgsl: Remove nonsense around the a5xx and a6xx
SMMU table update") removed a lot of the cruft around a pagetable update
but unfortunately legacy targets still needed APRIV to write to the
pagetable_desc memory so add that part back in.

The HFI error message has a 16 character error string attached. We should
not trust that the error string is properly formatted with a null
character at the end. Set the string precision to ensure that we only
print up to 16 characters of the payload.

If CP is not initialized and zap shader loading fails the GMU IFPC state
machine is uninitialized which causes unwanted mess. Reverse the order

Per-process pagetable support might be disabled in the arm-smmu driver for
any number of reasons but we won't know it until we try to create our
first dynamic domain. If enabling the dynamic domain returns -EOPNOTSUPP
then disable per-process pagetables and fall back to global pagetables.
Also, demote a WARN to a log-once message when the arm-smmu driver doesn't
support the system cache no-write-allocate tag.

Commit 2733ec307cd5 ("sound: usb: Clear in_use if wait_event
fails while disconnect") added ENODEV check with EINVAL in the
error path if chip is removed while handling uaudio stream request.
Instead, both the error codes should be checked exclusively in the
return path to avoid NULL pointer access.

In a case where the physical disconnect of headset
and the disable call from QMI race with each other,
there is a possibility that usb_sec_event_ring_cleanup
is called at the same time from uaudio_dev_cleanup
and uaudio_dev_release leading to kernel panic.
Fix this by seriailizing both these calls using
the dev_lock mutex.

Commit 02ec74e63187 ("sound: usb: Ensure proper cleanup of uaudio_dev
under all scenarios") fixed cyclic dependency between uaudio_dev_release
and uaudio_dev_cleanup by allowing dev_cleanup to happen if wait_event
of in_use to be cleared fails. Instead, clear in_use in disconnect_cb
if wait_event fails and don't rely on dev_release to happen, to maintain
the serialization of these calls.

Consider a case where chip is freed before disabling the audio
channel. This can happen when usb_audio_disconnect is called due
to USB DevFS proc_disconnect_claim ioctl. usb_audio_disconnect
will call uaudio_disconnect_cb which will wait for in_use to be
false to cleanup the uaudio_dev. If in_use never becomes false
and the wait_event is interrupted by some other signal then driver
bails out esrly from here and doesn't cleanup the uaudio_dev. Since
uaudio_dev_release is responsible for clearing the in_use based on
stream disable call, fix the cyclic dependency here on
uaudio_dev_release and uaudio_dev_cleanup by adding timeout in
wait_event and allowing dev_cleanup to happen from uaudio_disconnect_cb.
If disable stream request comes after this, handle_uaudio_stream_req
will still go ahead and try to find substream of the card but will
go to error path since card is already disconnected. This will set
the return value to -ENODEV but in the error path driver is not
checking for the correct return value and trying to access chip again.
Fix this by adding one more check for -ENODEV in the error handling path.

Consider a scenario where a context is valid when the check is made in
adreno_dispatcher_queue_cmds(), but by the time we reach _track_context(),
context has been detached. We would try to delete the entry from the
active context list as part of detaching the context though the entry is
not added yet. Now in _track_context() the context is actually added. When
the context is finally destroyed, we would be left with invalid entry in
the list. Next time when a context is added, an attempt would be made to
use a freed entry. Fix this by moving the entry deletion part under
drawctxt lock.
