[PATCH v3 0/2] drm: nouveau: memory coherency for ARM
v2 was doing some pretty nasty things with the DMA API, so I took a different
approach for this v3.
As suggested, this version uses ttm_dma_populate() to populate BOs. The reason
for doing this was that it would entitle us to using the DMA sync functions,
but since the memory returned is already coherent anyway, we do not even
need to call these functions anymore.
So this series has turned into
