Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "Exynos and Intel fixes.

  The intel fixes are fairly straightforward, mostly reverts due to bugs
  found.  The exynos one is a big larger since they found some issues
  with the G2D engine and iommu interaction, and needed to verify the
  operations a lot better than they were previously, otherwise a user
  app can just crash the kernel with an iommu fault."
