tmm 2002/07/12 09:26:50 PDT Modified files: 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).
