[PATCH v4 0/6] drm: nouveau: memory coherency on ARM
Another revision of this patchset critical for GK20A to operate.
Previous attempts were exclusively using either TTM's regular page allocator or
the DMA API one. Both have their advantages and drawbacks: the page allocator is
fast but requires explicit synchronization on non-coherent architectures,
whereas the DMA allocator always returns coherent memory, but is also slower,
creates a
