Daniel Vetter 03e0d26fcf drm/nouveau: slowpath for pushbuf ioctl ... We can't copy_*_user while holding reservations, that will (soon even for nouveau) lead to deadlocks. And it breaks the cross-driver contract around dma_resv. Fix this by adding a slowpath for when we need relocations, and by pushing the writeback of the new presumed offsets to the very end. Aside from "it compiles" entirely untested unfortunately.
