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.

+README file for the Linux g_NCR5380 driver.
+
+(c) 1993 Drew Eckhard
+NCR53c400 extensions (c) 1994,1995,1996 Kevin Lentin
+
+This file documents the NCR53c400 extensions by Kevin Lentin and some
+enhancements to the NCR5380 core.
+
+This driver supports both NCR5380 and NCR53c400 cards in port or memory
+mapped modes. Currently this driver can only support one of those mapping
+modes at a time but it does support both of these chips at the same time.
+The next release of this driver will support port & memory mapped cards at
+the same time. It should be able to handle multiple different cards in the
+same machine.
+
+The drivers/scsi/Makefile has an override in it for the most common
+NCR53c400 card, the Trantor T130B in its default configuration:
+	Port: 0x350
+	IRQ : 5
+
+The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
+supported by the driver.
+
+If the default configuration does not work for you, you can use the kernel
+command lines (eg using the lilo append command):
+	ncr5380=port,irq,dma
+	ncr53c400=port,irq
+or
+	ncr5380=base,irq,dma
+	ncr53c400=base,irq
+
+The driver does not probe for any addresses or ports other than those in
+the OVERRIDE or given to the kernel as above.
+
+This driver provides some information on what it has detected in
+/proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
+time. More info to come in the future.
+
+When NCR53c400 support is compiled in, BIOS parameters will be returned by
+the driver (the raw 5380 driver does not and I don't plan to fiddle with
+it!).
+
+This driver works as a module.
+When included as a module, parameters can be passed on the insmod/modprobe
+command line:
+  ncr_irq=xx   the interrupt
+  ncr_addr=xx  the port or base address (for port or memory
+               mapped, resp.)
+  ncr_dma=xx   the DMA
+  ncr_5380=1   to set up for a NCR5380 board
+  ncr_53c400=1 to set up for a NCR53C400 board
+e.g.
+modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
+  for a port mapped NCR5380 board or
+modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
+  for a memory mapped NCR53C400 board with interrupts disabled.
+
+(255 should be specified for no or DMA interrupt, 254 to autoprobe for an 
+     IRQ line if overridden on the command line.)
