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

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/memory/soft_offline_page
+Date:		Sep 2009
+KernelVersion:	2.6.33
+Contact:	andi@firstfloor.org
+Description:
+		Soft-offline the memory page containing the physical address
+		written into this file. Input is a hex number specifying the
+		physical address of the page. The kernel will then attempt
+		to soft-offline it, by moving the contents elsewhere or
+		dropping it if possible. The kernel will then be placed
+		on the bad page list and never be reused.
+
+		The offlining is done in kernel specific granuality.
+		Normally it's the base page size of the kernel, but
+		this might change.
+
+		The page must be still accessible, not poisoned. The
+		kernel will never kill anything for this, but rather
+		fail the offline.  Return value is the size of the
+		number, or a error when the offlining failed.  Reading
+		the file is not allowed.
