I could take care of the first 6 patches in this series, as they're only
touching AMD IOMMU code and look sensible to me. I'm not sure
though whether this is a good idea without knowing the disposition
of the other 10 patches (particularly the relative large 3rd patch
doesn't seem to make sense without it later getting hooked up).

Please let me know,
Jan
