The sparc64 code was still using it's local "call lock" in it's cpu hotplug code, yet that isn't used for smp_call_function() et al. any longer. Fix to use the locking interface exposed by the generic code. 2) Bug fix from Paul McKenney so that the online cpu map is cleared at the correct moment during cpu hotplug. Otherwise an offline CPU can receive an interrupt and lots of code does not like that. Please pull, thanks a lot. The following changes since commit dbb8c35d9063fe233626865cc836fbc102fa083b: David S.
