Pull drm updates from Dave Airlie:
"This is the main git pull for the drm,
I pretty much froze major pulls at -rc5/6 time, and haven't had much
fallout, so will probably continue doing that.
Lots of changes all over, big internal header cleanup to make it clear
drm features are legacy things and what are things that modern KMS
drivers should be using. Also big move to use the new generic fences
in all the TTM drivers.
core:
atomic prep work,
vblank rework changes, allows immediate vblank disables
major header reworking and cleanups to better delinate legacy
interfaces from what KMS drivers should be using.
cursor planes locking fixes
ttm:
move to generic fences (affects all TTM drivers)
ppc64 caching fixes
radeon:
userptr support,
uvd for old asics,
reset rework for fence changes
better buffer placement changes,
dpm feature enablement
hdmi audio support fixes
intel:
Cherryview work,
180 degree rotation,
skylake prep work,
execlist command submission
full ppgtt prep work
cursor improvements
edid caching,
vdd handling improvements
nouveau:
fence reworking
kepler memory clock work
gt21x clock work
fan control improvements
hdmi infoframe fixes
DP audio
ast:
ppc64 fixes
caching fix
rcar:
rcar-du DT support
ipuv3:
prep work for capture support
msm:
LVDS support for mdp4, new panel, gpu refactoring
exynos:
exynos3250 SoC support, drop bad mmap interface,
mipi dsi changes, and component match support"

Add a module paramter to enable bapm on APUs. It's disabled
by default on certain APUs due to stability issues. This
option makes it easier to test and to enable it on systems that
are stable.

bapm allows the GPU and CPU to share TDP. This allows
for additional performance out of the GPU and CPU when
the headroom is available.

Right now it's called right after enable, but after
reworking the dpm init order, it will get called later
to accomodate loading the smc early, but enabling
thermal interrupts and block powergating later after
the ring tests are complete.

Calling force_performance_level() from set_power_state()
doesn't work on some asics because the current power
state pointer has not been properly updated at that point.
Move the calls to force_performance_level() out of the
asic specific set_power_state() functions and into
the main power state sequence.
Fixes dpm resume on SI.

bapm is a power management feature for handling the
power budget between the CPU and GPU on APUs. This
patch adds support for enabling or disabling it.
For now disable it by default. Enabling it properly
requires quite a bit more work and will be addressed
in a separate patch.

The problem here is that "unsigned i" is always greater than or equal to
zero. These loops mostly have a second check for "(i == 0)" so only the
last two are actually buggy. The rest is just cleanup.
Bug 1: kv_force_dpm_highest() doesn't have an "(i == 0)" check so it's
a potential forever loop.
Bug 2: In kv_get_sleep_divider_id_from_clock() there is a typo and the
test is reversed "<=" vs ">" so we never enter the loop. That means
normally we return KV_MAX_DEEPSLEEP_DIVIDER_ID (5). The return value
from here is saved in ->DeepSleepDivId and I wasn't able to determine
how that is used. This is a static checker fix and I have not tested
it.

Newer versions of gcc seem to wander off into the
weeds when dealing with variable sizes arrays in
structs. Rather than indexing the arrays, use
pointer arithmetic.

Our different hardware blocks are actually completely
separated, so it doesn't make much sense any more to
structure the code by pure chipset generations.
Start restructuring the code by separating our the UVD block.
