From: Dave Airlie airlied@redhat.com
The core move code currently handles use_tt moves, for radeon this was being handled also in the driver, but not using the same paths.
If moving between TT/SYSTEM (all the use_tt paths on radeon) use the core move function.
Eventually the core will be flipped over to calling the driver.
