I'm submitting two patches associated with moving cache_reap functionality
out of timer context.  Note that these patches do not make any further
optimizations to cache_reap at this time.

The first patch adds a function similiar to schedule_delayed_work to allow
work to be scheduled on another cpu.

The second patch makes use of schedule_delayed_work_on to schedule
cache_reap to run from keventd.
