Yes.
intel_mmmap_range(domain, addr, end, phys_addr, prot)
Maybe think of a different name..? mmmap seems a bit weird :-)
Yes. I don't like it either. I've thought about it and haven't
figured out a satisfied one. Do you have any suggestions?
Best regards,

- Map an iova range of [addr, end) to the physical memory
started at @phys_addr with the @prot permissions.
intel_mmunmap_range(domain, addr, end)
- Tear down the map of an iova range [addr, end). A page
list will be returned which will be freed after iotlb
flushing.
