From ee6a3d19f15b9b10075481088b8d4537f286d7b4 Mon Sep 17 00:00:00 2001
From: Ingo Molnar <mingo@kernel.org>
Date: Mon, 6 Feb 2017 10:01:09 +0100
Subject: sched/headers: Remove the <linux/topology.h> include from
 <linux/sched.h>

It's used only by a single (rarely used) inline function (task_node(p)),
which we can move to <linux/sched/topology.h>.

( Add <linux/nodemask.h>, because we rely on that. )
