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.

+config CAPI_TRACE
+	bool "CAPI trace support"
+	default y
+	help
+	  If you say Y here, the kernelcapi driver can make verbose traces
+	  of CAPI messages. This feature can be enabled/disabled via IOCTL for
+	  every controller (default disabled).
+	  This will increase the size of the kernelcapi module by 20 KB.
+	  If unsure, say Y.
+
+config ISDN_CAPI_CAPI20
+	tristate "CAPI2.0 /dev/capi20 support"
+	help
+	  This option will provide the CAPI 2.0 interface to userspace
+	  applications via /dev/capi20. Applications should use the
+	  standardized libcapi20 to access this functionality.  You should say
+	  Y/M here.
+
+config ISDN_CAPI_MIDDLEWARE
+	bool "CAPI2.0 Middleware support"
+	depends on ISDN_CAPI_CAPI20 && TTY
+	help
+	  This option will enhance the capabilities of the /dev/capi20
+	  interface.  It will provide a means of moving a data connection,
+	  established via the usual /dev/capi20 interface to a special tty
+	  device.  If you want to use pppd with pppdcapiplugin to dial up to
+	  your ISP, say Y here.
+
+config ISDN_CAPI_CAPIDRV
+	tristate "CAPI2.0 capidrv interface support"
+	depends on ISDN_I4L
+	help
+	  This option provides the glue code to hook up CAPI driven cards to
+	  the legacy isdn4linux link layer.  If you have a card which is
+	  supported by a CAPI driver, but still want to use old features like
+	  ippp interfaces or ttyI emulation, say Y/M here.
+
+config ISDN_CAPI_CAPIDRV_VERBOSE
+	bool "Verbose reason code reporting"
+	depends on ISDN_CAPI_CAPIDRV
+	help
+	  If you say Y here, the capidrv interface will give verbose reasons
+	  for disconnecting. This will increase the size of the kernel by 7 KB.
+	  If unsure, say N.
