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.

+ * internal registers to 0xf1000000 (instead of the old 0xd0000000).
+ * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot
+ * bootloaders provided by Marvell. It is used in recent versions of
+ * DSM software provided by Synology. Nonetheless, some earlier boards
+ * were delivered with an older version of u-boot that left internal
+ * registers mapped at 0xd0000000. If you have such a device you will
+ * not be able to directly boot a kernel based on this Device Tree. In
+ * that case, the preferred solution is to update your bootloader (e.g.
+ * by upgrading to latest version of DSM, or building a new one and
+ * installing it from u-boot prompt) or adjust the Devive Tree
+ * (s/0xf1000000/0xd0000000/ in 'ranges' below).
