this is the next, bugfix release of the O(1) scheduler:


This release could fix the lockups and crashes reported by some people.


 - remove the likely/unlikely define from sched.h and include compiler.h.
   (Adrian Bunk)

 - export sys_sched_yield, reported by Pawel Kot.

 - turn off 'child runs first' temporarily, to see the effect.

 - export nr_context_switches() as well, needed by ReiserFS.

 - define resched_task() in the correct order to avoid compiler warnings
   on UP.

 - maximize the frequency of timer-tick driven load-balancing to 100 per

 - clear ->need_resched in the RT scheduler path as well.

 - simplify yield() support, remove TASK_YIELDED and __schedule_tail().
