[PATCH 00/10] ttm driver cleanups and invert move

[Dave Airlie]

The first 5 patches are just cleanups to remove unused functions
and handle ttm operation ctx nicer in driver move paths.

The last 5 patches have the goal to invert the operation of the
move driver callback. Currently the core does some tt related moves
itself and pass the drivers the rest. I'd like to have the driver
decide things instead, so only use the fallback paths when a driver
has no move callback.
