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.

+config IXP4XX_INDIRECT_PCI
+	bool "Use indirect PCI memory access"
+	depends on PCI
+	help
+          IXP4xx provides two methods of accessing PCI memory space:
+
+          1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
+             To access PCI via this space, we simply ioremap() the BAR
+             into the kernel and we can use the standard read[bwl]/write[bwl]
+             macros. This is the preferred method due to speed but it
+             limits the system to just 64MB of PCI memory. This can be
+             problematic if using video cards and other memory-heavy devices.
+
+	  2) If > 64MB of memory space is required, the IXP4xx can be
+	     configured to use indirect registers to access the whole PCI
+	     memory space. This currently allows for up to 1 GB (0x10000000
+	     to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
+	     is that every PCI access requires three local register accesses
+	     plus a spinlock, but in some cases the performance hit is
+	     acceptable. In addition, you cannot mmap() PCI devices in this
+	     case due to the indirect nature of the PCI window.
+
+	  By default, the direct method is used. Choose this option if you
+	  need to use the indirect method instead. If you don't know
+	  what you need, leave this option unselected.
