Subject: [PATCH] sched/numa: Pass destination CPU as a parameter to
 migrate_task_rq kabi

References: bnc#1101669 optimise numa balancing for fast migrate
Patch-mainline: never, kabi

This should be safe as no module should ever be accessing this opaque type
via task_struct.

[js] changed by commit 1327237a5978b00bcc665c33046c9bae75da1154.
