Juergen/Oleksandr/Xen Maintainers:
Would you take this patch through a xen related tree? The only reason
I had in this series is to make it easier to compile-test the gntdev
changes.
Since it is looking like the gntdev rework might not make it this
cycle it is probably best for you to take it.
Thanks,
Jason
