If you want this to be useful to Infiniband, you should probably
also hook up do_wp_page() in mm/memory.c, where a page table can
be pointed to another page.
Probably the code in mm/mremap.c will need to be hooked up too.
I imagine that many of the paravirt_ops mmu hooks will need to be
exposed as pte notifiers. This can't be done as part of the
paravirt_ops code due to the need to pass high level data structures,
though.

Any sufficiently difficult bug is indistinguishable from a feature.
