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:

    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.

+Kernel driver i2c-parport-light
+
+Author: Jean Delvare <jdelvare@suse.de>
+
+This driver is a light version of i2c-parport. It doesn't depend        
+on the parport driver, and uses direct I/O access instead. This might be
+preferred on embedded systems where wasting memory for the clean but heavy
+parport handling is not an option. The drawback is a reduced portability
+and the impossibility to daisy-chain other parallel port devices.                 
+  
+Please see i2c-parport for documentation.
+
+Module parameters:
+
+* type: type of adapter (see i2c-parport or modinfo)
+
+* base: base I/O address
+  Default is 0x378 which is fairly common for parallel ports, at least on PC.
+
+* irq: optional IRQ
+  This must be passed if you want SMBus alert support, assuming your adapter
+  actually supports this.
