RE: [Xen-devel] [PATCH] [VTD] Separate VT-d page table from P2M table

["Han, Weidong" <weidong.han@xxxxxxxxx>]

Separate VT-d page table is by default. Shared VT-d page table may be
easy and good in some cases. So we let them co-exist now. If shared VT-d
page table is not necessary and useless, we can remove it easily in
future.
