[Bug 524281] Re: Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled

This because of CONFIG_SCHED_DEBUG and CONFIG_SCHEDSTATS. Get rid of
these and wakeups shown in "[kernel scheduler] Load balancing tick" go
away. I just ran into by accident and compared my config with previous
version where I wasn't seeing this.

This was basically triggered by CONFIG_LATENCYTOP selection in the
menuconfig.
