Subject: [PATCH v4 0/3] Add option to mmap GEM buffers cached

Rework of this morning's v3 patchset.

The drm_gem_cma_prime_mmap() function that was added in v3 is now
replaced, instead we pass a "private" parameter to the
__drm_gem_cma_create() function.

Patches 2/3 and 3/3 are unmodified since v3.

Cheers,
-Paul

Paul Cercueil (3):
  drm: Add support for GEM buffers backed by non-coherent memory
  drm: Add and export function drm_gem_cma_sync_data
  drm/ingenic: Add option to alloc cached GEM buffers
