Doing this in a central place is certainly the right approach, but
adding an arch hook that needs to be called everywhere
vcpu_runstate_change() wouldn't serve that purpose. Instead
we'd need to replace all current vcpu_runstate_change() calls
with calls to a new function calling both this and the to be added
arch hook.

But please wait for George's / Dario's feedback, because they
seem to be even less convinced than me about your model of
tying the updates to runstate changes.
