Siddha, Suresh B fa3b6ddc3f [PATCH] sched: don't kick ALB in the presence of pinned task ...

Jack Steiner brought this issue at my OLS talk.

Take a scenario where two tasks are pinned to two HT threads in a physical
package.  Idle packages in the system will keep kicking migration_thread on
the busy package with out any success.

We will run into similar scenarios in the presence of CMP/NUMA.
