I imagine that many of the paravirt_ops mmu hooks will need to be

paravirt_ops code due to the need to pass high level data structures,
though.
Wait, I thought that paravirt_ops was all on the side of the
guest kernel, where these host kernel operations are invisible?
It is, but the hooks are in much the same places. It could be argued
that you'd embed pte notifiers in paravirt_ops for a host kernel, but
that's not doable because pte notifiers use higher-level data strutures
(like vmas).
