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.
