    sys/ia64/include     atomic.h 
  Log:
  For the atomic_{add|clear|set|subtract} family of inlines, return the
  old or previous value instead of void. This is not as is documented
  in atomic(9), but is API (and ABI) compatible and simply makes sense.
  This feature will primarily be used for atomic PTE updates in PMAP/ng.
