CONFIG_GENERIC_CLOCKEVENTS_BROADCAST isn't mandatory to
have SMP kernel working so the below select in ARM arch
kconfig not seems to entirely accurate. SMP kernel will
still boot with !GENERIC_CLOCKEVENTS_BROADCAST.

select GENERIC_CLOCKEVENTS_BROADCAST if SMP

The issue comes only for deeper CPU power C-states.
Anyway, you patch is correct from the current code point of
view.
