John Baldwin f933f02094 - Minimize the amount of duplicated code for the PREEMPTION #ifdef, it now ... only covers about 3-4 lines. - Don't lower the IPL while we are on the interrupt stack. Instead, save the raised IPL and change the saved IPL in sched_lock to IPL_0 before calling mi_switch(). When we are resumed, restore the saved IPL in sched_lock to the saved raised IPL so that when we release sched_lock we won't lower the IPL. Without this, we would get nested interrupts that would overflow the kernel stack. Tested by: mjacob		2001-02-05 19:34:25 +00:00
