Mekala Natarajan 5eea299803 sched: provide per cpu-cgroup option to notify on migrations ...

On systems where CPUs may run asynchronously, task migrations
between CPUs running at grossly different speeds can cause
problems.

This change provides a mechanism to notify a subsystem
in the kernel if a task in a particular cgroup migrates to a
different CPU. Other subsystems (such as cpufreq) may then
register for this notifier to take appropriate action when
such a task is migrated.

The cgroup attribute to set for this behavior is
"notify_on_migrate" .
