First a big "THANK YOU" for working on this and getting it ready. It is
an important step towards generic dma-ops for all iommu drivers,
something I wished to have for years and planned to work on myself, but
didn't find the time.

I applied this series to a new generic-dma-ops branch in the iommu
tree and plan to send it upstream in the next merge window.

Thanks again,
