Ok, great. Although I have to admit I feel about uneasy about
merging them for 5.2 unless Linus ends up doing an rc8. I plan to
pull the prep_coherent patch into the dma-mapping tree as we'll
need it as a prepation for other things as well, and then we can
just have an immutable tree with the dma-iommu changes, so that
it doesn't block other DMA mapping changes that will touch this
code as well.
