Log Message:
hypervisor_unmask_event(): don't check/update evtchn_pending_sel for the
   current CPU, but for any CPU which may accept this event.
xen/xenevt.c: more use of atomic ops and locks where appropriate, and some
   other SMP fixes. Handle all events on the primary CPU (may be revisited
   later). Set/clear ci_evtmask[] for watched events.

This should fix the problems on dom0 kernels reported by jym@



I can confirm that this fixes the problems I had starting domUs and 
ballooning with a -current dom0.   Thanks!
