Quite a bit of fallout all over the place, nothing terribly exciting.

This has been obsolescent for a while; time for the final push.

sched: Provide scheduler_ipi() callback in response to smp_send_reschedule()

2011-04-14T06:52:32+00:00

For future rework of try_to_wake_up() we'd like to push part of that
function onto the CPU the task is actually going to run on.

In order to do so we need a generic callback from the existing scheduler IPI.

This patch introduces such a generic callback: scheduler_ipi() and
implements it as a NOP.

BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!

sh: cache secondary CPUs idle loop.

2010-04-26T09:59:47+00:00

This provides a cache of the secondary CPUs idle loop for the cases where
hotplug simply enters a low power state instead of resetting or powering
off the core.

sh: flag smp_store_cpu_info() __cpuinit.

smp_store_cpu_info() is presently flagged as __init, but is called by
start_secondary() which is __cpuinit, fix it up.

This provides percpu CPU states in preparation for CPU hotplug and the
