BTW I discover an issue: init_evtchn sets HVM_PARAM_CALLBACK_IRQ every time it is called. That's unnecessary for APs. Perhaps it would be best to break that function into two, one for setting HVM_PARAM_CALLBACK_IRQ, the other for allocating and setting callback. BSP needs to call both while APs only needs to call the latter. This is out of scope for this series, but it is something to consider in the future.
