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

[Thomas Zimmermann <tzimmermann@suse.de>]

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)
