That way we can ditch our gem_prime_res_obj implementation. Since ttm absolutely needs the right reservation object all the boilerplate is already there and we just have to wire it up correctly. Note that gem/prime doesn't care when we do this, as long as we do it before the bo is registered and someone can call the handle2fd ioctl on it. Aside: ttm_buffer_object.ttm_resv could probably be ditched in favour of always passing a non-NULL resv to ttm_bo_init(). At least for gem drivers that would avoid having two of these, on in ttm_buffer_object and the other in drm_gem_object, one just there for confusion.
