Add the rt linux 4.1.3-rt3 as base

Import the rt linux 4.1.3-rt3 as OPNFV kvm base.

It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and
the base is:

commit 0917f823c59692d751951bf5ea699a2d1e2f26a2
Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date:   Sat Jul 25 12:13:34 2015 +0200

    Prepare v4.1.3-rt3

    Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+	help
+	  This provides a 'mapping' driver which allows the NOR Flash and
+	  ROM driver code to communicate with chips which are mapped
+	  physically into the CPU's memory. You will need to configure
+	  the physical address and size of the flash chips on your
+	  particular board as well as the bus width, either statically
+	  with config options or at run-time.
+
+	  To compile this driver as a module, choose M here: the
