This feature is for UMD to run benchmark in a
power state that is as steady as possible. kmd
need to fix the power state as stable as possible.
now, kmd support four level:
profile_standard,peak,min_sclk,min_mclk
move common related code to amd_powerplay.c

The call to kfd_device_by_id can potentially return null, so check that
dev is null and return with -EINVAL to avoid a null pointer dereference.

Pull gcc plugins update from Kees Cook:
"This finishes the porting work on randstruct, and introduces a new
option to structleak, both noted below:
- For the randstruct plugin, enable automatic randomization of
structures that are entirely function pointers (along with a couple
designated initializer fixes).
- For the structleak plugin, provide an option to perform zeroing
initialization of all otherwise uninitialized stack variables that
are passed by reference (Ard Biesheuvel)"

Pull drm updates from Dave Airlie:
"This is the main drm pull request for 4.14 merge window.
I'm sending this early, as my continuing journey into fatherhood is
occurring really soon now, I'm going to be mostly useless for the next
couple of weeks, though I may be able to read email, I doubt I'll be
doing much patch applications or git sending. If anything urgent pops
up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards
you.
Outside drm changes:
Some rcar-du updates that touch the V4L tree, all acks should be in
place. It adds one export to the radix tree code for new i915 use
case. There are some minor AGP cleanups (don't see that too often).

In VI, the destroy mqd function needs to inquire fields present in the mqd
structure. That's why we need to pass it to that function instead of NULL.

The header comment in include/trace/define_trace.h specifies that the
TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header
rather than the trace file including it. Most instances get that wrong
and work around it by adding the $(src) directory to the include path.
While this works, it is preferable to refer to the correct path to the
trace file in the first place and avoid any workaround.

Add the IOCTL interface so that applications can allocate per VM BOs.
Still WIP since not all corner cases are tested yet, but this reduces average
CS overhead for 10K BOs from 21ms down to 48us.
