Thanks for applying the fixes in the last submit.
In moving the test for no_missed_tick_accounting into
you forgot to add the scheduling part.

Actually it was deliberate, but clearly it was one code simplification too
far: thanks for spotting it! I'll go the async route, but we do need to set
pending_intr_nr to 1. We can't leave that out -- the point of the async
route is to send a tick to the vcpu immediately, since it hasn't had one for
more than a tick period. If we wait for the timeout to do that then we have
to wait a whole extra period after the vcpu is re-scheduled.

Attached is my proposed patch. I think it's quite neat. :-)
It looks good to me.
