  SVN rev 223463 on 2011-06-23 04:35:45Z by nwhitehorn
  
  Use atomic operations to mask and unmask IRQs. This prevents a problem
  (obvious in retrospect) in which interrupts on one CPU that are temporarily
  masked can end up permanently masked when a handler on another CPU clobbers
  the interrupt mask register with an old copy.
