From 76960dbf9b235b957d9d730be2c6c2a70f709026 Mon Sep 17 00:00:00 2001
From: Ingo Molnar <mingo@kernel.org>
Date: Fri, 3 Feb 2017 23:43:50 +0100
Subject: signals: Move signal data types from <linux/signal.h> to
 <linux/signal_types.h>

Separate out just the pure data types - sched.h will be able to use
this reduced size header.
