[Xen-devel] [RFC][PATCH][VTD] EPT/VT-d page table sharing

["Kay, Allen M" <allen.m.kay@xxxxxxxxx>]

Attached is EPT/VT-d page table sharing patch I mentioned earlier.  Basic idea 
is to leverage 2MB and 1GB page size support in EPT by having VT-d using the 
same page tables as EPT.  When EPT page table changes, flush VT-d IOTLB cache.

We are still further testing this patch but would appreciate feedbacks.
