The plan is to do load balancing using the smpnice feature, which is yet to be
worked on
From vatsa's comments
"Works only on UP for now (boot with maxcpus=1). IMO group-aware SMP
load-balancing can be met using smpnice feature. I will work on this
feature next."

The patch selects the task group first, based on priority. From the patch
"+ /* Pick a task group first */
+#ifdef CONFIG_CPUMETER "
Did I miss something?
