drm/ttm: drop persistent_swap_storage from ttm_bo_init and co

2018-02-27T04:09:45Z

Never used as parameter, the only driver actually using this is nouveau and there it is initialized after the BO is initialized. Signed-off-by: Christian König Reviewed-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/ttm: drop bo->glob

drm/ttm: set TTM_OPT_FLAG_FORCE_ALLOC in ttm_bo_force_list_clean

2018-02-27T04:09:34Z

Because ttm_bo_force_list_clean() is only called on two occasions: 1. By ttm_bo_evict_mm() during suspend. 2. By ttm_bo_clean_mm() when the driver unloads. On both cases we absolutely don't want any memory allocation failure. Signed-off-by: Roger He Reviewed-by: Christian König Signed-off-by: Alex Deucher
