The _arch_switch() API is a lower level context switching
primitive than the original __swap mechanism. It is required
for an SMP-aware scheduler, or if the architecture does not
provide __swap. In uniprocess situations where the
architecture provides both, _arch_switch incurs more somewhat
overhead and may be slower.
