[PATCH] paravirt: update pte hook
Add a pte_update_hook which notifies about pte changes that have been made without using the set_pte / clear_pte interfaces. This allows shadow mode hypervisors which do not trap on page table access to maintain synchronized shadows. It also turns out, there was one pte update in PAE mode that wasn't using any accessor interface at all for setting NX protection. Considering it is PAE specific, and the accessor is i386 specific, I didn't want to add a generic encapsulation of this behavior yet.
