What are your thoughts on having a mechanism to manage hypervisor

Potentially a scheduler activations interface would be nice for SMP
guests, if it's not too hard to modify the OS to support it. I don't
see how a preemption aware interface would improve
prepare_arch_switch() though -- I already said that failsafe_handler()
should pick up the slack if you remove selector zeroing from
prepare_arch_switch(). You may get some noise from Xen on a debug
build, but things should carry on working just fine.
If I'm missing your point, you need to give some more details about
what you're proposing. :-)
