IMO, I see the phys2mach mapping as a basic virtualization policy,

phys2mach concept to XEN/IA64, we can reuse more common code without
ifdef. Then correspondingly also need to add several necessary changes
like x86: DMA, SWIOTLB, AGP, etc, to ensure legal machine address
written into physical devices.
This seems to make sense to me. How does ia64/xen work right now?
Machine addresses visible to domain0 and full virtualisation of
addresses exposed to other domains (with no way of seeing underlying
machine addresses)?
