Say Y here to experiment with turning CPUs off and on. CPUs

This looks fine by me. Russell, would you like Jeff to submit this to
your patch tracking system?

Thanks,

This fixes a Kconfig warning on MSM:

warning: (PM_SLEEP_SMP) selects HOTPLUG_CPU which has unmet direct
dependencies (SMP && HOTPLUG && EXPERIMENTAL && !ARCH_MSM)

Is there any way we can get this merged for .39 final? It's 6863/1 in
the patch tracker.
