From f15cbe6f1a4b4d9df59142fc8e4abb973302cf44 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Tue, 29 Jul 2008 08:09:44 +0900
Subject: sh: migrate to arch/sh/include/
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.
Most of the moving about was done with Sam's directions at:
http://marc.info/?l=linux-sh&m=121724823706062&w=2
with subsequent hacking and fixups entirely my fault.
