Problem:

Due to an injudicious piece of code near the end of find_busiest_group() 
smpnice load balancing is too aggressive resulting in excessive movement 
of tasks from one CPU to another.

Solution:

Remove the offending code.  The thinking that caused it to be included 
became invalid when find_busiest_queue() was modified to use average 
load per task (on the relevant run queue) instead of SCHED_LOAD_SCALE 
when evaluating small imbalance values to see whether they warranted 
being moved.
