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.

+Welcome, friend reader, to lguest.
+
+Lguest is an adventure, with you, the reader, as Hero.  I can't think of many
+5000-line projects which offer both such capability and glimpses of future
+potential; it is an exciting time to be delving into the source!
+
+But be warned; this is an arduous journey of several hours or more!  And as we
+know, all true Heroes are driven by a Noble Goal.  Thus I offer a Beer (or
+equivalent) to anyone I meet who has completed this documentation.
+
+So get comfortable and keep your wits about you (both quick and humorous).
+Along your way to the Noble Goal, you will also gain masterly insight into
+lguest, and hypervisors and x86 virtualization in general.
+
+Our Quest is in seven parts: (best read with C highlighting turned on)
+
+I) Preparation
+	- In which our potential hero is flown quickly over the landscape for a
+	  taste of its scope.  Suitable for the armchair coders and other such
+	  persons of faint constitution.
+
+II) Guest
+	- Where we encounter the first tantalising wisps of code, and come to
+	  understand the details of the life of a Guest kernel.
+
+III) Drivers
+	- Whereby the Guest finds its voice and become useful, and our
+	  understanding of the Guest is completed.
+
+IV) Launcher
+	- Where we trace back to the creation of the Guest, and thus begin our
+	  understanding of the Host.
+
+V) Host
+	- Where we master the Host code, through a long and tortuous journey.
+	  Indeed, it is here that our hero is tested in the Bit of Despair.
+
+VI) Switcher
+	- Where our understanding of the intertwined nature of Guests and Hosts
+	  is completed.
+
+VII) Mastery
+	- Where our fully fledged hero grapples with the Great Question:
+	  "What next?"
+
+make Preparation!
+Rusty Russell.
