Modified files:
sys/kern sched_ule.c
Log:
- Move the rebalancer back into hardclock to prevent potential softclock
starvation caused by unbalanced interrupt loads.
- Change the rebalancer to work on stathz ticks but retain randomization.
- Simplify locking in tdq_idled() to use the tdq_lock_pair() rather than
complex sequences of locks to avoid deadlock.
