From 54b230e26a1889c08507e791ab043f8a4b4ff771 Mon Sep 17 00:00:00 2001
From: Romain Perier <romain.perier@free-electrons.com>
Date: Thu, 7 Jul 2016 14:40:53 +0200
Subject: [PATCH] Add support for Linux 4.4
It fixes various things like the use of seq_printf because its API
changed. It also replaces the call to mtrr_add and mtrr_del by
arch_phys_wc_add and arch_phys_wc_del because these symbols are
no longer exported for Linux >= 4.3.x.
