Modified files:
sys/kern sched_ule.c
Log:
- Move contents of sched_add() into a sched_add_internal() function that
takes an argument to specify if it should preempt or not. Don't preempt
when sched_add_internal() is called from kseq_idled() or kseq_assign()
as in those cases we are about to call mi_switch() anyways. Also, doing
so during the first context switch on an AP leads to a NULL pointer deref
because curthread is NULL.
- Reenable preemption for ULE.
