sh: Overhaul spinlocks and rwlocks for SH-4A SMP. This rips out some of the old spinlock and rwlock behaviour that the SH-2 parts were using and reworks them for LL/SC semantics on the SH-4A. This is primarily only useful for SH-X3 multi-cores, but can also be used for building CONFIG_SMP=y testing kernels on SH-4A UP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
