    But kmap_atomic_pte is a special case of kmap_atomic for ptes.
    Interrupt routines can still use plain kmap_atomic for bouncebuffers and
    so on.

    A more general patch would be to make kmap/unmap_atomic pv_ops, and then
    they can all be rolled together. I.e: check the type to see if special
    pte handling needs to happen, etc.
