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.

+	  Hardware Random Number Generator Core infrastructure.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called rng-core.  This provides a device
+	  that's usually called /dev/hw_random, and which exposes one
+	  of possibly several hardware random number generators.
+
+	  These hardware random number generators do not feed directly
+	  into the kernel's random number generator.  That is usually
+	  handled by the "rngd" daemon.  Documentation/hw_random.txt
+	  has more information.

+config UML_RANDOM
+	depends on UML
+	tristate "Hardware random number generator"
+	help
+	  This option enables UML's "hardware" random number generator.  It
+	  attaches itself to the host's /dev/random, supplying as much entropy
+	  as the host has, rather than the small amount the UML gets from its
+	  own drivers.  It registers itself as a standard hardware random number
+	  generator, major 10, minor 183, and the canonical device name is
+	  /dev/hwrng.
+	  The way to make use of this is to install the rng-tools package
+	  (check your distro, or download from
+	  http://sourceforge.net/projects/gkernel/).  rngd periodically reads
+	  /dev/hwrng and injects the entropy into /dev/random.
