[v4,0/3] Add option to mmap GEM buffers cached

Message

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
