sys/kern : sched_bsd.c
Log message:
Stop accounting/updating priorities for Idle threads.
Idle threads are never placed on the runqueue so their priority doesn't
matter.
This fixes an accounting bug where top(1) would report a high CPU usage
for Idle threads of secondary CPUs right after booting. That's because
schedcpu() would give 100% CPU time to the Idle thread until "real"
threads get scheduled on the corresponding CPU.
