Add a set of accessors to pack, unpack and modify page table entries (at all levels). This allows a paravirt implementation to control the contents of pgd/pmd/pte entries. For example, Xen uses this to convert the (pseudo-)physical address into a machine address when populating a pagetable entry, and converting back to pphys address when an entry is read.

Do you have some lmbench numbers before/after this change? iirc at least fork and exit do a lot of pte accesses in various forms. If it's measurable it might be needed to patch those for the native case.
