(you will probably need them when you will implement nested HYP mode :)).
Smiley noted, but this is pretty unlikely since it's not possible to lie to the guest about which mode it's in, so you can't make a guest think it's in Hyp mode.
I suspected this, but forgot most that I read about Hyp mode by now. Need to refresh my memory ASAP. Is it impossible even with a lot of emulation? Can guest detect that it is not in a Hyp mode without trapping into hypervisor?
