Enable retention of memory and periphery logics for
GPU core clock. If the setting is not done then GPU
might get stale data while switching from NAP to
ACTIVE and which leads to page faults or hangs.
Clock settings need to be handled by client drivers only
and hence do it in KGSL driver.

Qualcomm Technologies Inc vendor specific wlan driver (qcacld-3.0)
internally supports wow mode and is enabled by default.
Currently, cfg80211 subsystem and wpa_supplicant is not aware of
qcacld-3.0 internal support for wowlan, due to which wpa_supplicant
is issuing disconnect on suspend, resulting in wowlan failure.
To fix this, avoid disconnect on suspend.

Below is the synchronization issue between unmount and kjournald2
contexts, which results into use after free issue in kjournald2().
Fix this issue by using journal->j_state_lock to synchronize the
wait_event() done in journal_kill_thread() and the wake_up() done
in kjournald2().
TASK 1:
umount cmd:
|--jbd2_journal_destroy() {
|--journal_kill_thread() {
write_lock(&journal->j_state_lock);
journal->j_flags |= JBD2_UNMOUNT;
...
write_unlock(&journal->j_state_lock);
wake_up(&journal->j_wait_commit); TASK 2 wakes up here:
kjournald2() {
...
checks JBD2_UNMOUNT flag and calls goto end-loop;
...
end_loop:
write_unlock(&journal->j_state_lock);
journal->j_task = NULL; --> If this thread gets
pre-empted here, then TASK 1 wait_event will
exit even before this thread is completely
done.
wait_event(journal->j_wait_done_commit, journal->j_task == NULL);
...
write_lock(&journal->j_state_lock);
write_unlock(&journal->j_state_lock);
}
|--kfree(journal);
}
}
wake_up(&journal->j_wait_done_commit); --> this step
now results into use after free issue.
}

If possible that after suspend, cfg80211 will receive request to
disconnect what require action on interface that was removed during
suspend.
Problem can manifest itself by various warnings similar to below one:

To fix the problem disconnect from any associated network before
suspend. User space is responsible to establish connection again
after resume. This basically need to be done by user space anyway,
because associated stations can go away during suspend (for example
NetworkManager disconnects on suspend and connect on resume by default).
Patch also handle situation when driver refuse to suspend with wowlan
configured and try to suspend again without it.
