[PATCH] Use for_each_cpu() Where It's Meant To Be
From: Rusty Russell <rusty@rustcorp.com.au>
Some places use cpu_online() where they should be using cpu_possible, most
commonly for tallying statistics. This makes no difference without hotplug
CPU.
Use the for_each_cpu() macro in those places, providing good examples (and
making the external hotplug CPU patch smaller).
