sys/sparc64/include smp.h
Log:
When sending cache flushing IPIs, don't try to IPI the triggering CPU
itself; this causes undefined behaviour on UltraSPARCs. In particular,
the interrupt packet data words will not necessarily be delivered
correctly, which would result in a crash.
This bug also caused the cache-flushing work to be done twice on the
triggering CPU (when it did not cause crashes).
