Xen devel - Sep 2009 - [PATCH] [IOMMU] dynamic VTd page table for HVM guest

This patch makes HVM''s VTd page table dynamic just like what PV guest
does, so that avoid the overhead of maintaining page table until a PCI
device is truly assigned to the HVM guest.

Wei,
This patch also remove some duplicated codes on your side, and is safe
in theory. You can have a check.
Thanks,
