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, Joerg
