Ok, I applied 1-5 to their respective branches. Patch 6 needs some more
discussion to make sure the interface is generally usable. Patch 7 seems
to be a starting point for now. This definitly requires conversion of
the other IOMMU drivers too.
Please make individual patch-sets from patch 6 and 7 respectivly.
