Dave Airlie	d6ea88865d	drm/ttm: Add a bo list reserve fastpath (v2) ... Makes it possible to reserve a list of buffer objects with a single spin lock / unlock if there is no contention. Should improve cpu usage on SMP kernels. v2: Initialize private list members on reserve and don't call ttm_bo_list_ref_sub() with zero put_count.
