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.

+What:		/sys/devices/system/xen_memory/xen_memory0/max_retry_count
+Date:		May 2011
+KernelVersion:	2.6.39
+Contact:	Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
+Description:
+		The maximum number of times the balloon driver will
+		attempt to increase the balloon before giving up.  See
+		also 'retry_count' below.
+		A value of zero means retry forever and is the default one.

+Date:		May 2011
+KernelVersion:	2.6.39

+Description:
+		The limit that 'schedule_delay' (see below) will be
+		increased to. The default value is 32 seconds.

+Date:		May 2011
+KernelVersion:	2.6.39
+Contact:	Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
+Description:
+		The current number of times that the balloon driver
+		has attempted to increase the size of the balloon.
+		The default value is one. With max_retry_count being
+		zero (unlimited), this means that the driver will attempt
+		to retry with a 'schedule_delay' delay.

+What:		/sys/devices/system/xen_memory/xen_memory0/schedule_delay
+Date:		May 2011
+KernelVersion:	2.6.39
+Contact:	Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
+Description:
+		The time (in seconds) to wait between attempts to
+		increase the balloon.  Each time the balloon cannot be
+		increased, 'schedule_delay' is increased (until
+		'max_schedule_delay' is reached at which point it
+		will use the max value).
