I think we want to get rid of the "generic" iommu API and make it x86 specific at this stage. A lot of what the guest is going to do with the iommu is really platform specific at this stage, especially when we start adding the EEH functionality, which is PE-based, or when we want to implement the guest calls for creating dynamic windows.
