Subject: [PATCH] drm/ttm: call driver move_notify() when doing system->tt bo moves
Nouveau doesn't have enough information at ttm_backend_func.bind() time
to implement things like tiled GART, or to keep a buffer at a constant
address in the GPU virtual address space no matter where in physical
memory it's placed.
To resolve this, nouveau will handle binding of all buffers to the GPU
itself from the move_notify() hook. This commit ensures it's called
for all buffer moves.
