[PATCH v2 0/3] drm: Make DRM hashtable legacy

Clean up the last non-legacy users of DRM's hashtable code and put
the code behind CONFIG_DRM_LEGACY.

TTM only includes the header file, but does not use the hashtable.
The vmwgfx driver uses the hashtable internally. Copy the DRM code
into the driver. A later patchset should probably update vmwgfx to
use Linux' hashtable. Finally, make the core hashtable code legacy.

Built with/without CONFIG_DRM_LEGACY set.

v2:
	* add TODO item for updating vmwgfx (Sam)

  drm/ttm: Don't include drm_hashtab.h
  drm/vmwgfx: Copy DRM hash-table code into driver
  drm: Declare hashtable as legacy
