Modified files:
sys/alpha/include atomic.h
sys/alpha/alpha atomic.s
Log:
Remove extranious memory barriers, and correct the placement of a few others.
This provides a 30% reduction in system time and a 6% reduction in wallclock time
for a make buildworld on my xp1000 (one 21264).
FWIW, I've been running this for nearly 2 months without problems.
