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.

+Module Parameters
+-----------------
+force_addr=0xaddr	Set the I/O base address. Useful for boards
+			that don't set the address in the BIOS. Does not do a
+			PCI force; the device must still be present in lspci.
+			Don't use this unless the driver complains that the
+			base address is not set.
+			Example: 'modprobe sis5595 force_addr=0x290'

+Description
+-----------
+
+The SiS5595 southbridge has integrated hardware monitor functions. It also
+has an I2C bus, but this driver only supports the hardware monitor. For the
+I2C bus driver see i2c-sis5595.
+
+The SiS5595 implements zero or one temperature sensor, two fan speed
+sensors, four or five voltage sensors, and alarms.
+
+On the first version of the chip, there are four voltage sensors and one
+temperature sensor.
+
+On the second version of the chip, the temperature sensor (temp) and the
+fifth voltage sensor (in4) share a pin which is configurable, but not
+through the driver. Sorry. The driver senses the configuration of the pin,
+which was hopefully set by the BIOS.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the max is crossed; it is also triggered when it drops below the min
+value. Measurements are guaranteed between -55 and +125 degrees, with a
+resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt.
+
+In addition to the alarms described above, there is a BTI alarm, which gets
+triggered when an external chip has crossed its limits. Usually, this is
+connected to some LM75-like chip; if at least one crosses its limits, this
+bit gets set.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The SiS5595 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+Problems
+--------
+Some chips refuse to be enabled. We don't know why.
+The driver will recognize this and print a message in dmesg.
