[Nouveau] [PATCH v2 0/4] drm: Generic dumb_map_offset for TTM-based drivers

[Thomas Zimmermann]

The implementation of drm_driver.dumb_map_offset is the same for several
TTM-based drivers. Provide a common function in GEM-TTM helpers.

[PATCH v2 2/4] drm/vram-helper: Use drm_gem_ttm_dumb_map_offset()

[Thomas Zimmermann]

VRAM helpers now use drm_gem_ttm_dumb_map_offset() to implement
struct drm_driver.dumb_map_offset.

v2:
	* update hibmc as well (kernel test robot)
