Message-Id: <1486387772-18837-58-git-send-email-mingo@kernel.org>
Date: Mon, 6 Feb 2017 14:29:00 +0100
From: Ingo Molnar <mingo@...nel.org>
To: linux-kernel@...r.kernel.org
Cc: Andrew Morton <akpm@...ux-foundation.org>,

Subject: [PATCH 57/89] sched/headers: Split <linux/sched/task_stack> out of <linux/sched.h>
Split out the task->stack related functionality, which is not really
part of the core scheduler APIs.
Update the code that uses those facilities.
