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.

+config SLIP
+	tristate "SLIP (serial line) support"
+	depends on TTY
+	---help---
+	  Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
+	  connect to your Internet service provider or to connect to some
+	  other local Unix box or if you want to configure your Linux box as a
+	  Slip/CSlip server for other people to dial in. SLIP (Serial Line
+	  Internet Protocol) is a protocol used to send Internet traffic over
+	  serial connections such as telephone lines or null modem cables;
+	  nowadays, the protocol PPP is more commonly used for this same
+	  purpose.
+
+	  Normally, your access provider has to support SLIP in order for you
+	  to be able to use it, but there is now a SLIP emulator called SLiRP
+	  around (available from
+	  <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
+	  allows you to use SLIP over a regular dial up shell connection. If
+	  you plan to use SLiRP, make sure to say Y to CSLIP, below. The
+	  NET-3-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, explains how to
+	  configure SLIP. Note that you don't need this option if you just
+	  want to run term (term is a program which gives you almost full
+	  Internet connectivity if you have a regular dial up shell account on
+	  some Internet connected Unix computer. Read
+	  <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
+	  support will enlarge your kernel by about 4 KB. If unsure, say N.
+
+	  To compile this driver as a module, choose M here. The module
+	  will be called slip.
+
+config SLHC
+	tristate
+	---help---
+	  This option enables Van Jacobsen serial line header compression
+	  routines.
+
+if SLIP
+
+config SLIP_COMPRESSED
+	bool "CSLIP compressed headers"
+	depends on SLIP
+	select SLHC
+	---help---
+	  This protocol is faster than SLIP because it uses compression on the
+	  TCP/IP headers (not on the data itself), but it has to be supported
+	  on both ends. Ask your access provider if you are not sure and
+	  answer Y, just in case. You will still be able to use plain SLIP. If
+	  you plan to use SLiRP, the SLIP emulator (available from
+	  <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
+	  allows you to use SLIP over a regular dial up shell connection, you
+	  definitely want to say Y here. The NET-3-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, explains how to configure
+	  CSLIP. This won't enlarge your kernel.
+
+config SLIP_SMART
+	bool "Keepalive and linefill"
+	depends on SLIP
+	---help---
+	  Adds additional capabilities to the SLIP driver to support the
+	  RELCOM line fill and keepalive monitoring. Ideal on poor quality
+	  analogue lines.
+
+config SLIP_MODE_SLIP6
+	bool "Six bit SLIP encapsulation"
+	depends on SLIP
+	---help---
+	  Just occasionally you may need to run IP over hostile serial
+	  networks that don't pass all control characters or are only seven
+	  bit. Saying Y here adds an extra mode you can use with SLIP:
+	  "slip6". In this mode, SLIP will only send normal ASCII symbols over
+	  the serial device. Naturally, this has to be supported at the other
+	  end of the link as well. It's good enough, for example, to run IP
+	  over the async ports of a Camtec JNT Pad. If unsure, say N.
