Sorry for the delay, I had a look at the generic IOMMU and the AMD part
now. It looks good to me so far, but I still have to review the VT-d
changes and give it all some testing on my machines. I really like the
code simplification in the IOMMU drivers and also feel more comfortable
when the IVRS table is still taken into consideration for getting
aliases.
