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 C6X_BIG_KERNEL
+	bool "Build a big kernel"
+	help
+	  The C6X function call instruction has a limited range of +/- 2MiB.
+	  This is sufficient for most kernels, but some kernel configurations
+	  with lots of compiled-in functionality may require a larger range
+	  for function calls. Use this option to have the compiler generate
+	  function calls with 32-bit range. This will make the kernel both
+	  larger and slower.
+
+	  If unsure, say N.

+	help
+	  On some architectures there is currently no way for the boot loader
+	  to pass arguments to the kernel. For these architectures, you should
+	  supply some command-line options at build time by entering them
+	  here.
+
+config CMDLINE_FORCE
+	bool "Force default kernel command string"

+
+config CPU_BIG_ENDIAN
+	bool "Build big-endian kernel"
+	default n
+	help
+	  Say Y if you plan on running a kernel in big-endian mode.
+	  Note that your board must be properly built and your board
+	  port must properly enable any big-endian related features
+	  of your chipset/board/processor.
+
+config FORCE_MAX_ZONEORDER
+	int "Maximum zone order"
+	default "13"
+	help
+	  The kernel memory allocator divides physically contiguous memory
+	  blocks into "zones", where each zone is a power of two number of
+	  pages.  This option selects the largest power of two that the kernel
+	  keeps in the memory allocator.  If you need to allocate very large
+	  blocks of physically contiguous memory, then you may need to
+	  increase this value.
+
+	  This config option is actually maximum order plus one. For example,
+	  a value of 11 means that the largest free memory block is 2^10 pages.
