In the past these were simply wrapping to barrier() which was sufficient on SH SMP platforms predating SH-4A. Unfortunately due to ll/sc semantics an explicit synco is needed in these cases, which is sorted for us by just switching these over to smp_mb(). smp_mb() also has the benefit of being wrapped to barrier() in the UP and non-SH4A cases, so old behaviour is maintained for those parts.
