the code looks very clean. I guess down the line we might want to think about making all the externally visible knobs transparent: there should be only one way to disable the iommu via the boot command line (be that an AMD or Intel one), etc.
i have created a new -tip topic for this: tip/x86/amd-iommu and have applied your patches there - thanks Joerg. You can pick up the integrated tree via:
http://people.redhat.com/mingo/tip.git/README
please check whether the integrated end result still works fine. [ Obviously nobody but you can test this on real hw ;-) ]
