    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:

    please check whether the integrated end result still works fine.
    [ Obviously nobody but you can test this on real hw ;-) ]
