Really, an external interface to KVM that allowed someone to query the GPA => PA mapping would suffice. It should not fault in pages that aren't present and we should provide notifications for when the mapping changes for a given reason. Userspace can enforce the requirement that memory remains present via mlock(). This allows us to implement a PV API for DMA registration without the IOMMU code having any particular knowledge of it.
