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

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+Power Architecture CPU Binding
+Copyright 2013 Freescale Semiconductor Inc.
+
+Power Architecture CPUs in Freescale SOCs are represented in device trees as
+per the definition in ePAPR.
+
+In addition to the ePAPR definitions, the properties defined below may be
+present on CPU nodes.
+
+PROPERTIES
+
+   - fsl,eref-*
+        Usage: optional
+        Value type: <empty>
+        Definition: The EREF (EREF: A Programmer.s Reference Manual for
+	Freescale Power Architecture) defines the architecture for Freescale
+	Power CPUs.  The EREF defines some architecture categories not defined
+	by the Power ISA.  For these EREF-specific categories, the existence of
+	a property named fsl,eref-[CAT], where [CAT] is the abbreviated category
+	name with all uppercase letters converted to lowercase, indicates that
+	the category is supported by the implementation.
+
+    - fsl,portid-mapping
+	Usage: optional
+	Value type: <u32>
+	Definition: The Coherency Subdomain ID Port Mapping Registers and
+	Snoop ID Port Mapping registers, which are part of the CoreNet
+	Coherency fabric (CCF), provide a CoreNet Coherency Subdomain
+	ID/CoreNet Snoop ID to cpu mapping functions.  Certain bits from
+	these registers should be set if the coresponding CPU should be
+	snooped.  This property defines a bitmask which selects the bit
+	that should be set if this cpu should be snooped.
