the patches for AMD IOMMU emulation are not yet upstream has you have
already noticed. Eduard is busy with his studies at the moment so any
help is greatly appreciated :)
Feel free to pick up hist patches and re-submit them (keeping the author
correct of course).
If you submit your code, it would be cool if you could put me on Cc so I
can easily follow the discussion and jump in if required.
