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.

+	tristate "FMC support"
+	help
+
+	  FMC (FPGA Mezzanine Carrier) is a mechanical and electrical
+	  standard for mezzanine cards that plug into a carrier board.
+	  This kernel subsystem supports the matching between carrier
+	  and mezzanine based on identifiers stored in the internal I2C
+	  EEPROM, as well as having carrier-independent drivers.
+
+	  The framework was born outside of the kernel and at this time
+	  the off-tree code base is more complete.  Code and documentation
+	  is at git://ohwr.org/fmc-projects/fmc-bus.git .
+
+if FMC
+
+config FMC_FAKEDEV
+	tristate "FMC fake device (software testing)"
+	help
+	  This is a fake carrier, bringing a default EEPROM content
+	  that can be rewritten at run time and usef for matching
+	  mezzanines.
+
+config FMC_TRIVIAL
+	tristate "FMC trivial mezzanine driver (software testing)"
+	help
+	  This is a fake mezzanine driver, to show how FMC works and test it.
+	  The driver also handles interrupts (we used it with a real carrier
+	  before the mezzanines were produced)
+
+config FMC_WRITE_EEPROM
+	tristate "FMC mezzanine driver to write I2C EEPROM"
+	help
+	  This driver matches every mezzanine device and can write the
+	  internal EEPROM of the PCB, using the firmware loader to get
+	  its binary and the function carrier->reprogram to actually do it.
+	  It is useful when the mezzanines are produced.
+
+config FMC_CHARDEV
+	tristate "FMC mezzanine driver that registers a char device"
+	help
+	  This driver matches every mezzanine device and allows user
+	  space to read and write registers using a char device. It
+	  can be used to write user-space drivers, or just get
+	  acquainted with a mezzanine before writing its specific driver.
