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 ISDN_PPP
+	bool "Support synchronous PPP"
+	depends on INET
+	select SLHC
+	help
+	  Over digital connections such as ISDN, there is no need to
+	  synchronize sender and recipient's clocks with start and stop bits
+	  as is done over analog telephone lines. Instead, one can use
+	  "synchronous PPP". Saying Y here will include this protocol. This
+	  protocol is used by Cisco and Sun for example. So you want to say Y
+	  here if the other end of your ISDN connection supports it. You will
+	  need a special version of pppd (called ipppd) for using this
+	  feature. See <file:Documentation/isdn/README.syncppp> and
+	  <file:Documentation/isdn/syncPPP.FAQ> for more information.
+
+config ISDN_PPP_VJ
+	bool "Use VJ-compression with synchronous PPP"
+	depends on ISDN_PPP
+	help
+	  This enables Van Jacobson header compression for synchronous PPP.
+	  Say Y if the other end of the connection supports it.
+
+config ISDN_MPP
+	bool "Support generic MP (RFC 1717)"
+	depends on ISDN_PPP
+	help
+	  With synchronous PPP enabled, it is possible to increase throughput
+	  by bundling several ISDN-connections, using this protocol. See
+	  <file:Documentation/isdn/README.syncppp> for more information.
+
+config IPPP_FILTER
+	bool "Filtering for synchronous PPP"
+	depends on ISDN_PPP
+	help
+	  Say Y here if you want to be able to filter the packets passing over
+	  IPPP interfaces.  This allows you to control which packets count as
+	  activity (i.e. which packets will reset the idle timer or bring up
+	  a demand-dialled link) and which packets are to be dropped entirely.
+	  You need to say Y here if you wish to use the pass-filter and
+	  active-filter options to ipppd.
+
+config ISDN_PPP_BSDCOMP
+	tristate "Support BSD compression"
+	depends on ISDN_PPP
+	help
+	  Support for the BSD-Compress compression method for PPP, which uses
+	  the LZW compression method to compress each PPP packet before it is
+	  sent over the wire. The machine at the other end of the PPP link
+	  (usually your ISP) has to support the BSD-Compress compression
+	  method as well for this to be useful. Even if they don't support it,
+	  it is safe to say Y here.
+
+config ISDN_AUDIO
+	bool "Support audio via ISDN"
+	help
+	  If you say Y here, the modem-emulator will support a subset of the
+	  EIA Class 8 Voice commands. Using a getty with voice-support
+	  (mgetty+sendfax by <gert@greenie.muc.de> with an extension, available
+	  with the ISDN utility package for example), you will be able to use
+	  your Linux box as an ISDN-answering machine. Of course, this must be
+	  supported by the lowlevel driver also. Currently, the HiSax driver
+	  is the only voice-supporting driver. See
+	  <file:Documentation/isdn/README.audio> for more information.
+
+config ISDN_TTY_FAX
+	bool "Support AT-Fax Class 1 and 2 commands"
+	depends on ISDN_AUDIO
+	help
+	  If you say Y here, the modem-emulator will support a subset of the
+	  Fax Class 1 and 2 commands. Using a getty with fax-support
+	  (mgetty+sendfax, hylafax), you will be able to use your Linux box as
+	  an ISDN-fax-machine. This must be supported by the lowlevel driver
+	  also. See <file:Documentation/isdn/README.fax> for more information.
+
+config ISDN_X25
+	bool "X.25 PLP on top of ISDN"
+	depends on X25
+	help
+	  This feature provides the X.25 protocol over ISDN connections.
+	  See <file:Documentation/isdn/README.x25> for more information
+	  if you are thinking about using this.
+
+
+menu "ISDN feature submodules"
+
+config ISDN_DRV_LOOP
+	tristate "isdnloop support"
+	depends on BROKEN_ON_SMP
+	help
+	  This driver provides a virtual ISDN card. Its primary purpose is
+	  testing of linklevel features or configuration without getting
+	  charged by your service-provider for lots of phone calls.
+	  You need will need the loopctrl utility from the latest isdn4k-utils
+	  package to set up this driver.
+
+config ISDN_DIVERSION
+	tristate "Support isdn diversion services"
+	help
+	  This option allows you to use some supplementary diversion
+	  services in conjunction with the HiSax driver on an EURO/DSS1
+	  line.
+
+	  Supported options are CD (call deflection), CFU (Call forward
+	  unconditional), CFB (Call forward when busy) and CFNR (call forward
+	  not reachable). Additionally the actual CFU, CFB and CFNR state may
+	  be interrogated.
+
+	  The use of CFU, CFB, CFNR and interrogation may be limited to some
+	  countries. The keypad protocol is still not implemented. CD should
+	  work in all countries if the service has been subscribed to.
+
+	  Please read the file <file:Documentation/isdn/README.diversion>.
