4223 i8254 (PIT) has two modes, reinject and !reinject. The default is reinject,
4224 where KVM queues elapsed i8254 ticks and monitors completion of interrupt from
4225 vector(s) that i8254 injects. Reinject mode dequeues a tick and injects its
4226 interrupt whenever there isn't a pending interrupt from i8254.
