[PATCH] sched domain: increase the SMT busy rebalance interval
With SMT, if the logical processor is busy, load balance happens for every 8msec(min)-16msec(max). There is no need to do this often, as this is just for fairness(to maintain uniform runqueue lengths) and default time slice anyhow is 100msec. Appended patch increases this interval to 64msec(min)-128msec(max) when the logical processor is busy.
