The ast and mgag200 drivers pin() and kmap() cursor buffers; essentially
reimplementing vmap(). We can share some code by using the respective
functionality from GEM VRAM buffer objects.
Thomas Zimmermann (3):
drm/vram: Provide vmap and vunmap operations for GEM VRAM objects
drm/ast: Use drm_gem_vram_{vmap,vunmap}() to map cursor source BO
drm/mgag200: Use drm_gem_vram_{vmap,vunmap}() to map cursor source BO
