Are either of you happy to pick this series up now that we have Hanjun's
acks for the IORT parts? As it stands it still applies cleanly to both
iommu/next and dma/for-next. I do have some followup IOMMU patches
prepared already (continuing to delete more code, yay!), but I don't
want to get too far ahead of myself.

Cheers,
Robin.
