Modified files:
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.
