  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.
