Subject: [PATCH 2/5] workqueue: rename kernel/workqueue_sched.h to
 kernel/workqueue_internal.h

>From ea138446e51f7bfe55cdeffa3f1dd9cafc786bd8 Mon Sep 17 00:00:00 2001

Workqueue wants to expose more interface internal to kernel/.  Instead
of adding a new header file, repurpose kernel/workqueue_sched.h.
Rename it to workqueue_internal.h and add include protector.

This patch doesn't introduce any functional changes.

Ingo, Peter, changes to scheduler is trivial.  If there's no
objection, I'd like to route this with the rest of workqueue and async
changes.

Thanks.
