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.

+
+Speakup is a kernel based screen review package for the linux operating
+system.  It allows blind users to interact with applications on the
+linux console by means of synthetic speech.
+
+Currently, speakup has several issues we know of.
+
+The first issue has to do with the way speakup communicates with serial
+ports.  Currently, we communicate directly with the hardware
+ports. This however conflicts with the standard serial port drivers,
+which poses various problems. This is also not working for modern hardware
+such as PCI-based serial ports.  Also, there is not a way we can
+communicate with USB devices.  The current serial port handling code is
+in serialio.c in this directory.
+
+Some places are currently using in_atomic() because speakup functions
+are called in various contexts, and a couple of things can't happen
+in these cases. Pushing work to some worker thread would probably help,
+as was already done for the serial port driving part.
+
+There is a duplication of the selection functions in selections.c. These
+functions should get exported from drivers/char/selection.c (clear_selection
+notably) and used from there instead.
+
+The kobjects may have to move to a more proper place in /sys. The
+discussion on lkml resulted to putting speech synthesizers in the
+"speech" class, and the speakup screen reader itself into
+/sys/class/vtconsole/vtcon0/speakup, the nasty path being handled by
+userland tools.
+
+Another issue seems to only happen on SMP systems.  It seems
+that text in the output buffer gets garbled because a lock is not set.
+This bug happens regularly, but no one has been able to find a situation
+which produces it consistently.
+
+Patches, suggestions, corrections, etc, are definitely welcome.
