Well, I forgot about it. I think the plan was to perhaps keep something like
continue_hypercall_on_cpu(), but not need to actually run the vcpu itself
'over there' but instead schedule a tasklet or somesuch, and sleep on its
completion. That would get rid of the skanky affinity hacks you had to do to
support continue_hypercall_on_cpu(). I'll have a look back at what we
discussed.
