Hi Tom,

can you rebase this on top of this series:

https://lists.linuxfoundation.org/pipermail/iommu/2019-March/034357.html

or the version addressing Robin's comments here:

http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/dma-iommu-ops.3

so that we can avoid introducing more dma_map_ops boilerplate code?
