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 ;-) ]
