Re: NUMA scheduler broken

Looks like __activate_task() should call nr_running_inc(rq) rather than
rq->nr_running++, and the same in wake_up_forked_process(). My guess
is that the bogus node_nr_running value is causing some really poor
scheduling decisions to be made on NUMA. See if that changes your result.
