TTM uses global memory and BO for backing graphics buffers. These are represented by struct ttm_mem_global and struct ttm_bo_global. Currently, struct ttm_bo_global can only be initialized and released through struct ttm_bo_global_ref. This is a workaround for passing an instance of ttm_mem_global to the BO global initialization code. The use of struct ttm_bo_global_ref makes driver code
