seokhoon.yoon efca03ecbe schedcore: Remove duplicated init_task's preempt_notifiers init 
init_task's preempt_notifiers is initialized twice:

1) sched_init()
   -> INIT_HLIST_HEAD(&init_task.preempt_notifiers)

2) sched_init()
   -> init_idle(current,) <--- current task is init_task at this time
    -> __sched_fork(,current)
     -> INIT_HLIST_HEAD(&p->preempt_notifiers)

I think the first one is unnecessary, so remove it.
