So appart from the one issue in the "memory controller integration"
patch this looks good and I've acked the remaining patches. Once the one
remaining issue is fixed I think this is ready to be merged.

Joerg, given the dependencies between the various parts of the series, I
think it may be better for you to merge everything through the IOMMU
tree if you don't mind.
