From: Ben Skeggs <bskeggs@xxxxxxxxxx>
In order to properly deal with GPU reordering of blocks in physical VRAM,
Nouveau needs to be able to have better control over VRAM allocations.
Currently nouveau is extremely wasteful and forces massive amounts of
padding/alignment to avoid buffer corruption issues.
radeon/vmwgfx haven't been tested, but nouveau works as well as it did
previously.

drm/ttm: introduce utility function to free an allocated memory node
drm/ttm: restructure to allow driver to plug in alternate memory
