In shadow mode hypervisors, ptep_get_and_clear achieves the desired

modified.
Direct mode hypervisors (Xen) have no need for this anyway, and will trap
the update using writable pagetables.
This means no hypervisor makes use of ptep_get_and_clear; there is no
reason to have it in the paravirt-ops structure. Change confusing
terminology about raw vs. native functions into consistent use of
native_pte_xxx for operations which do not invoke paravirt-ops.
Looks OK to me. Are you going to put this into the pvops queue?

Yes, the rest are still undergoing feedback. I'll kick this in and
fixup the damage it causes.
