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.

+ * A constraint is a condition that must be satisfied in
+ * order for one or more permissions to be granted.
+ * Constraints are used to impose additional restrictions
+ * beyond the type-based rules in `te' or the role-based
+ * transition rules in `rbac'.  Constraints are typically
+ * used to prevent a process from transitioning to a new user
+ * identity or role unless it is in a privileged type.
+ * Constraints are likewise typically used to prevent a
+ * process from labeling an object with a different user
+ * identity.
