Subject: [PATCH 0/4] drm/ttm: nouveau: memory coherency fixes for ARM

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:

Another patch takes care of flushing the CPU write-buffer when writing BOs
through a non-BAR path.

Alexandre Courbot (1):
  drm/nouveau: introduce CPU cache flushing macro

Lucas Stach (3):
  drm/ttm: recognize ARM arch in ioprot handler
  drm/ttm: introduce dma cache sync helpers
  drm/nouveau: hook up cache sync functions
