Module Name:	src
Committed By:	ad
Date:		Thu Aug 30 20:02:33 UTC 2007

Modified Files:
	src/sys/kern [vmlocking]: kern_cpu.c subr_xcall.c
	src/sys/sys [vmlocking]: cpu_data.h xcall.h

Log Message:
- Instead of xc_broadcast()/xc_unicast() waiting for completion, have them
  return a value which can later be passed to xc_wait(). Allows the caller
  to go and do other stuff in the meantime.
- Fix the xcall thread to work properly in the event of a spurious wakeup.
