Log Message:
propagate the MP idle-loop fix to ppc from the other ports:

  Move call to sched_unlock_idle to later in the context switch to
  eliminate a race where another processor could grab the outgoing
  process before we were done saving our state into it, with predictable
  results.

  Bug spotted by Frank van der Linden <fvdl@wasabisystems.com>

also, don't re-enable interrupts temporarily in the middle of
switching to a new process, just wait until we're completely switched.
this didn't work on MP and it's not worth the effort.
