Thread-topic:	[Xen-devel] [PATCH] [VTD] Fix free VT-d page table issue

This patch frees VT-d page tables from pgd, rather than free them
according to a guest address range. 

BTW, this patch fixes [Bug 1244] Poweroff/Destroying HVM guest causes HV
crash. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1244.
