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" .
