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.

+Module options
+--------------
+
+The mwave module takes the following options.  Note that these options
+are not saved by the BIOS and so do not persist after unload and reload.
+
+  mwave_debug=value, where value is bitwise OR of trace flags:
+	0x0001 mwavedd api tracing
+	0x0002 smapi api tracing
+	0x0004 3780i tracing
+	0x0008 tp3780i tracing
+
+        Tracing only occurs if the driver has been compiled with the
+        MW_TRACE macro #defined  (i.e. let ccflags-y := -DMW_TRACE
+        in the Makefile).
+
+  mwave_3780i_irq=5/7/10/11/15
+	If the dsp irq has not been setup and stored in bios by the 
+	thinkpad configuration utility then this parameter allows the
+	irq used by the dsp to be configured.
+
+  mwave_3780i_io=0x130/0x350/0x0070/0xDB0
+	If the dsp io range has not been setup and stored in bios by the 
+	thinkpad configuration utility then this parameter allows the
+	io range used by the dsp to be configured.
+
+  mwave_uart_irq=3/4
+	If the mwave's uart irq has not been setup and stored in bios by the 
+	thinkpad configuration utility then this parameter allows the
+	irq used by the mwave uart to be configured.
+
+  mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
+	If the uart io range has not been setup and stored in bios by the 
+	thinkpad configuration utility then this parameter allows the
+	io range used by the mwave uart to be configured.
+
+Example to enable the 3780i DSP using ttyS1 resources:
+	
+  insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
+
+Accessing the driver
+--------------------
+
+You must also create a node for the driver:
+  mkdir -p /dev/modems
+  mknod --mode=660 /dev/modems/mwave c 10 219
+
