sys/sparc64/sparc64 mp_machdep.c
Log:
Do as the USII CPU manual suggests and leave interrupts enabled
for a bit before retrying to resend an IPI in order to avoid
deadlocks if the other CPU is also trying to send one.
OpenSolaris uses a delay of 1 microsecond here but waiting 2
microseconds with interrupts enabled like Linux does shouldn't
hurt but is a bit safer.
