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.

+Submitting Drivers For The Linux Kernel
+---------------------------------------
+
+This document is intended to explain how to submit device drivers to the
+various kernel trees. Note that if you are interested in video card drivers
+you should probably talk to XFree86 (http://www.xfree86.org/) and/or X.Org
+(http://x.org/) instead.
+
+Also read the Documentation/SubmittingPatches document.
+
+
+Allocating Device Numbers
+-------------------------
+
+Major and minor numbers for block and character devices are allocated
+by the Linux assigned name and number authority (currently this is
+Torben Mathiasen). The site is http://www.lanana.org/. This
+also deals with allocating numbers for devices that are not going to
+be submitted to the mainstream kernel.
+See Documentation/devices.txt for more information on this.
+
+If you don't use assigned numbers then when your device is submitted it will
+be given an assigned number even if that is different from values you may
+have shipped to customers before.
+
+Who To Submit Drivers To
+------------------------
+
+Linux 2.0:
+	No new drivers are accepted for this kernel tree.
+
+Linux 2.2:
+	No new drivers are accepted for this kernel tree.
+
+Linux 2.4:
+	If the code area has a general maintainer then please submit it to
+	the maintainer listed in MAINTAINERS in the kernel file. If the
+	maintainer does not respond or you cannot find the appropriate
+	maintainer then please contact Willy Tarreau <w@1wt.eu>.
+
+Linux 2.6:
+	The same rules apply as 2.4 except that you should follow linux-kernel
+	to track changes in API's. The final contact point for Linux 2.6
+	submissions is Andrew Morton.
+
+What Criteria Determine Acceptance
+----------------------------------
+
+Licensing:	The code must be released to us under the
+		GNU General Public License. We don't insist on any kind
+		of exclusive GPL licensing, and if you wish the driver
+		to be useful to other communities such as BSD you may well
+		wish to release under multiple licenses.
+		See accepted licenses at include/linux/module.h
+
+Copyright:	The copyright owner must agree to use of GPL.
+		It's best if the submitter and copyright owner
+		are the same person/entity. If not, the name of
+		the person/entity authorizing use of GPL should be
+		listed in case it's necessary to verify the will of
+		the copyright owner.
+
+Interfaces:	If your driver uses existing interfaces and behaves like
+		other drivers in the same class it will be much more likely
+		to be accepted than if it invents gratuitous new ones.
+		If you need to implement a common API over Linux and NT
+		drivers do it in userspace.
+
+Code:		Please use the Linux style of code formatting as documented
+		in Documentation/CodingStyle. If you have sections of code
+		that need to be in other formats, for example because they
+		are shared with a windows driver kit and you want to
+		maintain them just once separate them out nicely and note
+		this fact.
+
+Portability:	Pointers are not always 32bits, not all computers are little
+		endian, people do not all have floating point and you
+		shouldn't use inline x86 assembler in your driver without
+		careful thought. Pure x86 drivers generally are not popular.
+		If you only have x86 hardware it is hard to test portability
+		but it is easy to make sure the code can easily be made
+		portable.
+
+Clarity:	It helps if anyone can see how to fix the driver. It helps
+		you because you get patches not bug reports. If you submit a
+		driver that intentionally obfuscates how the hardware works
+		it will go in the bitbucket.
+
+PM support:	Since Linux is used on many portable and desktop systems, your
+		driver is likely to be used on such a system and therefore it
+		should support basic power management by implementing, if
+		necessary, the .suspend and .resume methods used during the
+		system-wide suspend and resume transitions.  You should verify
+		that your driver correctly handles the suspend and resume, but
+		if you are unable to ensure that, please at least define the
+		.suspend method returning the -ENOSYS ("Function not
+		implemented") error.  You should also try to make sure that your
+		driver uses as little power as possible when it's not doing
+		anything.  For the driver testing instructions see
+		Documentation/power/drivers-testing.txt and for a relatively
+		complete overview of the power management issues related to
+		drivers see Documentation/power/devices.txt .
+
+Control:	In general if there is active maintenance of a driver by
+		the author then patches will be redirected to them unless
+		they are totally obvious and without need of checking.
+		If you want to be the contact and update point for the
+		driver it is a good idea to state this in the comments,
+		and include an entry in MAINTAINERS for your driver.
+
+What Criteria Do Not Determine Acceptance
+-----------------------------------------
+
+Vendor:		Being the hardware vendor and maintaining the driver is
+		often a good thing. If there is a stable working driver from
+		other people already in the tree don't expect 'we are the
+		vendor' to get your driver chosen. Ideally work with the
+		existing driver author to build a single perfect driver.
+
+Author:		It doesn't matter if a large Linux company wrote the driver,
+		or you did. Nobody has any special access to the kernel
+		tree. Anyone who tells you otherwise isn't telling the
+		whole story.
