Stefano's patches are based on the latest Xen branches which support
dom0 but his work is focused on domU. That is because there is a lot of
similarity between the needs of dom0 and the needs of PVonHVM event
channels so it makes sense to leverage one for the other.

I think we'd be better served in extracting the bits of the domain0
patchset which support/enable Stefano's patches and pushing that stuff
upstream as a complete series. Otherwise we basically need to
reimplement domain 0 stuff on top of / alongside your patcheset.
