Log Message:
(MULTIPROCESSOR version of) need_resched:
- nothing needs to be done if ci_want_resched is already set.
- if the cpu isn't running any lwp, send a no-op ipi to it
  so that it can resume immediately from halting in idle loop
  without having to wait until the next clock tick.
some advices from Stephan Uphoff.
