Modified Files:
src/sys/arch/xen/include: evtchn.h hypervisor.h
src/sys/arch/xen/x86: hypervisor_machdep.c
src/sys/arch/xen/xen: evtchn.c
Log Message:
Simplify the xen event handler callback by:
- moving the interrupt handler callback traversal into a separate
function.
- using evt_iterate_bits() to scan through the pending bitfield
- removing cross-cpu pending actions - events recieved on the wrong
vcpu are re-routed via hypervisor_send_event().
- simplifying nested while() loops by encapsulating them in
equivalent functions.
