Pull drm fixes from Dave Airlie: "Just back from LCA + some days off, had some fixes from the past 2 weeks, Some amdkfd code removal for a feature that wasn't ready, otherwise just one fix for core helper sleeping, exynos, i915, and radeon fixes. I thought I had some sti fixes but they were already in, and it confused me for a few mins this morning" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm: fb helper should avoid sleeping in panic context drm/exynos: fix warning of vblank reference count drm/exynos: remove unnecessary runtime pm operations drm/exynos: fix reset codes for memory mapped hdmi phy drm/radeon: use rv515_ring_start on r5xx drm/radeon: add si dpm quirk list drm/radeon: don't print error on -ERESTARTSYS drm/i915: Fix mutex->owner inspection race under DEBUG_MUTEXES drm/i915: Ban Haswell from using RCS flips drm/i915: vlv: sanitize RPS interrupt mask during GPU idling drm/i915: fix HW lockup due to missing RPS IRQ workaround on GEN6 drm/i915: gen9: fix RPS interrupt routing to CPU vs. GT drm/exynos: remove the redundant machine checking code drm/radeon: add a dpm quirk list drm/amdkfd: Fix sparse warning (different address space) drm/radeon: fix VM flush on CIK (v3) drm/radeon: fix VM flush on SI (v3) drm/radeon: fix VM flush on cayman/aruba (v3) drm/amdkfd: Drop interrupt SW ring buffer
