The commit fd6681cd4d0782f6e6ac918ab337016f59c2520b introduced
a silent bug that incorrectly checks state of the clock while
setting the next timer event. The bug manifests only during
failure code path of msm idle operation, which is very rare.
Due to the bug, the driver isn't be able to reprogram the timer
device.

Use the default setstate function, which directly reprograms the IOMMU,
to change IOMMU pagetables or flush the TLB if the GPU is already idle.
This condition often occurs when the GPU is being powered down. In this
case it is desirable to avoid the overhead of issuing commands, waiting
for idle and firing events that results from using the GPU
command stream to reprogram the IOMMU.

There has two bugs.
1. For example, the 'psaux' device will use '1' as minor number to
register misc device, but misc deriver doesn't set the '1' as used.
It's the root casue for duplicate filename.
2. From warning message, minor number '1' is the one of duplicate
fileanme, it meanes the number of dynamic minor is not enough.
The symptom of creating duplicate filename:

Avoid holding ashmem_mutex across code that can page fault. Page faults
grab the mmap_sem for the process, which are also held by mmap calls
prior to calling ashmem_mmap, which locks ashmem_mutex. The reversed
order of locking between the two can deadlock.
The calls that can page fault are read() and the ASHMEM_SET_NAME and
ASHMEM_GET_NAME ioctls. Move the code that accesses userspace pages
outside the ashmem_mutex.

In the original code logic, when auto-brightness turned on, the
unset_bl_level would be 0. Thus no backlight command when starting
to encrypt.
Do not set unset_bl_level to 0. The logic by unset_bl_level could
be mentained by bl_updated.
Note that mipi command mode panel need extra backlight command in
msm_fb_commit_wq_handler. If we embeded the backlight command in
power on sequence, there would be screen mess when panel power on.

The trustee code already takes a lock internal to the workqueue
implementation and is not expecting a wake up to come around and
enter the workqueue code again, where the same lock will be needed.
Instead of relying on a workqueue, use a per-CPU kthread to do
the frequency syncing.

In the process of scaling CPU frequencies, cpufreq and the APIS is
calls may hold resources that will prevent threads critical for
system stability from running.
Specifically, thermal-mitigation software may need to respond
quickly to high-temperature conditions and throttle the CPU speed
in an effort to cool down. If the system is already in the middle
of a CPU frequency switch being executed on behalf of a cpufreq
governor, thermal mitigation will be blocked until the scaling
action has completed. If the system is under heave load of medium
or high-priority threads, this may take a long while and the system
may potentially surpass thermal limits in the meantime.
Resolve this by using high priority workqueues for all ondemand
and conservative governor scaling operations. This will allow them
to complete promptly and release their hold on resources necessary
for maintaining system stability.

Commit 88a7e37d265 (sched: provide per cpu-cgroup option to
notify on migrations) added a notifier call when a task is moved
to a different CPU. Unfortunately the two call sites in the RT
sched class where this occurs happens with a runqueue lock held.
This can result in a deadlock if the notifier call attempts to do
something like wake up a task.
Fortunately the benefit of 88a7e37d265 comes mainly from notifying
on migration of non-RT tasks, so we can simply ignore the movements
of RT tasks.
