Subject: [PATCH v5 0/3] Add option to mmap GEM buffers cached

V5 of my patchset which adds the option for having GEM buffers backed by
non-coherent memory.

Changes from V4:

- [2/3]: 
    - Rename to drm_fb_cma_sync_non_coherent
    - Invert loops for better cache locality
    - Only sync BOs that have the non-coherent flag
    - Properly sort includes
    - Move to drm_fb_cma_helper.c to avoid circular dependency

- [3/3]:
    - Fix drm_atomic_get_new_plane_state() used to retrieve the old
      state
    - Use custom drm_gem_fb_create()
    - Only check damage clips and sync DMA buffers if non-coherent
      buffers are used

Cheers,
-Paul
