CVS commit: src/sys/arch/xen

["Cherry G. Mathew" <cherry%netbsd.org@localhost>]

Module Name:    src
Committed By:   cherry
Date:           Fri Dec 28 06:29:56 UTC 2012

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.

Many thanks for multiple reviews by bouyer@ and jym@
