[Devel] [PATCH rh7] sched: debug: show nr_failed_migrations_cpulimit

[Vladimir Davydov]

This is our (non-mainstream) counter counting how many times task
migration failed due to cpulimit restriction. For some reason, we don't
show it in proc although it might be helpful for debugging. Let's fix
that.
