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.

+menuconfig IIO
+	tristate "Industrial I/O support"
+	select ANON_INODES
+	help
+	  The industrial I/O subsystem provides a unified framework for
+	  drivers for many different types of embedded sensors using a
+	  number of different physical interfaces (i2c, spi, etc).
+
+if IIO
+
+config IIO_BUFFER
+	bool "Enable buffer support within IIO"
+	help
+	  Provide core support for various buffer based data
+	  acquisition methods.
+
+if IIO_BUFFER
+
+config IIO_BUFFER_CB
+	bool "IIO callback buffer used for push in-kernel interfaces"
+	help
+	  Should be selected by any drivers that do in-kernel push
+	  usage.  That is, those where the data is pushed to the consumer.
+
+config IIO_KFIFO_BUF
+	tristate "Industrial I/O buffering based on kfifo"
+	help
+	  A simple fifo based on kfifo.  Note that this currently provides
+	  no buffer events so it is up to userspace to work out how
+	  often to read from the buffer.
+
+config IIO_TRIGGERED_BUFFER
+	tristate
+	select IIO_TRIGGER
+	select IIO_KFIFO_BUF
+	help
+	  Provides helper functions for setting up triggered buffers.
+
+endif # IIO_BUFFER
+
+config IIO_TRIGGER
+	bool "Enable triggered sampling support"
+	help
+	  Provides IIO core support for triggers.  Currently these
+	  are used to initialize capture of samples to push into
+	  buffers.  The triggers are effectively a 'capture
+	  data now' interrupt.
+
+config IIO_CONSUMERS_PER_TRIGGER
+       int "Maximum number of consumers per trigger"
+       depends on IIO_TRIGGER
+       default "2"
+       help
+	This value controls the maximum number of consumers that a
+	given trigger may handle. Default is 2.
