The ttm_move_memcpy() function was intended to be able to be used async under a fence. We are going to utilize that as a fallback if the gpu clearing blit fails before we set up CPU- or GPU ptes to the memory region. But to accomplish that the bo argument to ttm_move_memcpy() needs to be replaced.
Patch 1 reorganizes the i915 ttm move code a bit to make the change in patch 2 smaller. Patch 2 updates the ttm_move_memcpy() interface.
v2: - Don't initialize memcpy iterators until they are actually needed (Patch 1). - Added proper R-B:s and Cc:s
