HYBRID: (PV in HVM) update

HYBRID: (PV in HVM) update

[Mukesh Rathor]

JFYI... So I had a third type is_hybrid in my prototype, that I thought
I could get rid of, and hide things under is_hvm check. But that just
touches too much code, and things get ugly a bit all over.

It seems I could just mark the guest PV if not EPT and using PV paging,
and mark it HVM if EPT enabled to keep changes minimum, and just
check for hybrid where needed (so add is_hybrid back in). Trying that
now....

thanks
Mukesh

YEAY guys!!! I now have PV in HVM guest running with EPT! 
I'll clean up the code (tons of debug stuff right now), and post
it for anyone to look at. 

Next and final frontier after that, running it as dom0.

thanks,
mukesh
