[V6 PATCH 0/7]: PVH dom0....
Hi,
V6: The only change from V5 is in patch #6:
- changed comment to reflect autoxlate
- removed a redundant ASSERT
- reworked logic a bit so that get_page_from_gfn() is called with NULL

Tim: patch 4 needs your approval.
Daniel: patch 5 needs your approval.
These patches implement PVH dom0.
