[PATCH v4 01/17] drm/ttm: add gem base object

[Gerd Hoffmann]

Add drm_gem_object struct to ttm_buffer_object, so ttm objects are a gdm
object superclass.  Add a function to check whenever a given bo actually
uses the embedded drm_gem_object.

[PATCH v4 09/17] drm/ttm: set both resv and base.resv pointers

[Gerd Hoffmann]

Initialize both ttm_buffer_object->resv and ttm_buffer_object->base.resv
pointers.  This allows to move users from the former to the latter.  When
all users are moved we can drop ttm_buffer_object->resv.
