That would be tricky because there are multiple paths (gfn_to_page,
gfn_to_pfn, etc.).
There is some complication in this because the new device has to be
plumbed at multiple levels (KVM, QEMU, libvirt). But it seems like a
very easily separated piece of code (except for the KVMI socket part,
which can be added later), so I suggest that you contribute the KVM
parts first....
