Subject: [PATCH 0/5] drm/msm: add MSM_BO_CACHED_COHERENT (and related changes)

Add support for MSM_BO_CACHED_COHERENT, a coherent version of MSM_BO_CACHED
which is implemented by setting the IOMMU_CACHE flag.

Jonathan Marek (5):
  drm/msm: remove unnecessary mmap logic for cached BOs
  drm/msm: replace MSM_BO_UNCACHED with MSM_BO_WC for internal objects
  drm/msm: use the right pgprot when mapping BOs in the kernel
  drm/msm: add MSM_BO_CACHED_COHERENT
  drm/msm: deprecate MSM_BO_UNCACHED (map as writecombine instead)
