This small series introduces TTM helper functions as well as Nouveau hooks that are needed to ensure buffer coherency on ARM. Most of this series is a forward-port of some patches Lucas Stach sent last year and that are also needed for Nouveau GK20A support: http://lists.freedesktop.org/archives/nouveau/2013-August/014026.html Another patch takes care of flushing the CPU write-buffer when
