[Intel-gfx] [PATCH v2 0/2] drm/i915, drm/ttm: Update the ttm_move_memcpy() interface

[Thomas Hellström]

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
