Richard Kennedy	dd5fde6041	drm/ttm: remove padding from ttm_ref_object on 64bit builds Re-order structure ttm_ref_object to remove 8 bytes of alignment padding on 64 bit builds, so shrinking its size from 72 to 64 bytes allowing it to fit into a smaller slab.

drm/ttm: Add user-space objects.

Add objects needed for user-space to maintain reference counts on ttm objects.
This is used by the vmwgfx driver which allows user-space to maintain
map-counts on dma buffers, lock-counts on the ttm lock and ref-counts on
gpu surfaces, gpu contexts and dma buffer.
