i've got an ugly fix for an SMP scheduling problem i found tonight, maybe
it has some effect on uniprocessors too? dunno, anyways:
add this to line 374 of 2.1.3[12] sched.c:
if ( (!next->pid) && (prev->state==TASK_RUNNING) )
next = prev;
it works for me, but it might be a totally broken thing. It fixes the SMP
performance problems i had in 2.1.3[012].
