Two SMP fixes for sparc64:
1) Conversion to generic SMP call function helpers didn't update the
locking. 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.
