Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: "Xmas fixes pull: core: one atomic fix, revert the WARN_ON dumb buffers patch. agp: fixup Dave J. nouveau: fix 3.18 regression for old userspace tegra fixes: vblank and iommu fixes amdkfd: fix bugs shown by testing with userspace, init apertures once msm: hdmi fixes and cleanup i915: misc fixes There is also a link ordering fix that I've asked to be cc'ed to you, putting iommu before gpu, it fixes an issue with amdkfd when things are all in the kernel, but I didn't like sending it via my tree without discussion. I'll probably be a bit on/off for a few weeks with pulls now, due to holidays and LCA, so don't be surprised if stuff gets a bit backed up, and things end up a bit large due to lag" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (28 commits) Revert "drm/gem: Warn on illegal use of the dumb buffer interface v2" agp: Fix up email address & attributions in AGP MODULE_AUTHOR tags nouveau: bring back legacy mmap handler drm/msm/hdmi: rework HDMI IRQ handler drm/msm/hdmi: enable regulators before clocks to avoid warnings drm/msm/mdp5: update irqs on crtc<->encoder link change drm/msm: block incoming update on pending updates drm/atomic: fix potential null ptr on plane enable drm/msm: Deletion of unnecessary checks before the function call "release_firmware" drm/msm: Deletion of unnecessary checks before two function calls drm/tegra: dc: Select root window for event dispatch drm/tegra: gem: Use the proper size for GEM objects drm/tegra: gem: Flush buffer objects upon allocation drm/tegra: dc: Fix a potential race on page-flip completion drm/tegra: dc: Consistently use the same pipe drm/irq: Add drm_crtc_vblank_count() drm/irq: Add drm_crtc_handle_vblank() drm/irq: Add drm_crtc_send_vblank_event() drm/i915: Disable PSMI sleep messages on all rings around context switches drm/i915: Force the CS stall for invalidate flushes ...
