Modified files:
sys/alpha/include atomic.h
Log:
* Redo the cmpset inlines to use one less register. This incidentally
fixes a serious problem with the previous version where an input could
have been placed in the same register as an output which would stop
the inline from working properly.
* Redo atomic_{set,clear,add,subtract}_{32,64} as inlines since the code
sequence is shorter than the call sequence to the code in atomic.s.
I will remove the functions from atomic.s after a grace period to allow
people to rebuild kernel modules.
