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_i2c: int
+  Initialize the I2C address of the sensors
+* init: int
+  (default is 1)
+  Use 'init=0' to bypass initializing the chip.
+  Try this if your computer crashes when you load the module.

+Description
+-----------
+
+This driver implements support for ISA accesses *only* for
+the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
+We will refer to them collectively as Winbond chips.
+
+This driver supports ISA accesses, which should be more reliable
+than i2c accesses. Also, for Tyan boards which contain both a
+Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
+using this driver will avoid i2c address conflicts and complex
+initialization that were required in the w83781d driver.
+
+If you really want i2c accesses for these Super I/O chips,
+use the w83781d driver. However this is not the preferred method
+now that this ISA driver has been developed.
+
+The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the
+same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a
+VID reading. However the two chips have the identical 128 pin package. So,
+it is possible or even likely for a w83627thf to have the VID signals routed
+to these pins despite their not being labeled for that purpose. Therefore,
+the w83627thf driver interprets these as VID. If the VID on your board
+doesn't work, first see doc/vid in the lm_sensors package[1]. If that still
+doesn't help, you may just ignore the bogus VID reading with no harm done.
+
+For further information on this driver see the w83781d driver documentation.

+
+Forcing the address
+-------------------
+
+The driver used to have a module parameter named force_addr, which could
+be used to force the base I/O address of the hardware monitoring block.
+This was meant as a workaround for mainboards with a broken BIOS. This
+module parameter is gone for technical reasons. If you need this feature,
+you can obtain the same result by using the isaset tool (part of
+lm-sensors) before loading the driver:
+
+# Enter the Super I/O config space
+isaset -y -f 0x2e 0x87
+isaset -y -f 0x2e 0x87
+
+# Select the hwmon logical device
+isaset -y 0x2e 0x2f 0x07 0x0b
+
+# Set the base I/O address (to 0x290 in this example)
+isaset -y 0x2e 0x2f 0x60 0x02
+isaset -y 0x2e 0x2f 0x61 0x90
+
+# Exit the Super-I/O config space
+isaset -y -f 0x2e 0xaa
+
+The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
+0x4e/0x4f is also possible.
+
+Voltage pin mapping
+-------------------
+
+Here is a summary of the voltage pin mapping for the W83627THF. This
+can be useful to convert data provided by board manufacturers into
+working libsensors configuration statements.
+
+    W83627THF		|
+  Pin	| Name		| Register	| Sysfs attribute
+-----------------------------------------------------
+  100	| CPUVCORE	| 20h		| in0
+   99	| VIN0		| 21h		| in1
+   98	| VIN1		| 22h		| in2
+   97	| VIN2		| 24h		| in4
+  114	| AVCC		| 23h		| in3
+   61	| 5VSB		| 50h (bank 5)	| in7
+   74	| VBAT		| 51h (bank 5)	| in8
+
+For other supported devices, you'll have to take the hard path and
+look up the information in the datasheet yourself (and then add it
+to this document please.)
