Merge tag 'drm-fixes-2019-10-04' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
"Been offline for 3 days, got back and had some fixes queued up.

Nothing too major, the i915 dp-mst fix is important, and amdgpu has a
bulk move speedup fix and some regressions, but nothing too insane for
an rc2 pull. The intel fixes are also 2 weeks worth, they missed the
boat last week.

core:
- writeback fixes

i915:
- Fix DP-MST crtc_mask
- Fix dsc dpp calculations
- Fix g4x sprite scaling stride check with GTT remapping
- Fix concurrence on cases where requests where getting retired at
same time as resubmitted to HW
- Fix gen9 display resolutions by setting the right max plane width
- Fix GPU hang on preemption
- Mark contents as dirty on a write fault. This was breaking cursor
sprite with dumb buffers.

komeda:
- memory leak fix

tilcdc:
- include fix

amdgpu:
- Enable bulk moves
- Power metrics fixes for Navi
- Fix S4 regression
- Add query for tcc disabled mask
- Fix several leaks in error paths
- randconfig fixes
- clang fixes"
