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 XFS_FS
+	tristate "XFS filesystem support"
+	depends on BLOCK
+	depends on (64BIT || LBDAF)
+	select EXPORTFS
+	select LIBCRC32C
+	help
+	  XFS is a high performance journaling filesystem which originated
+	  on the SGI IRIX platform.  It is completely multi-threaded, can
+	  support large files and large filesystems, extended attributes,
+	  variable block sizes, is extent based, and makes extensive use of
+	  Btrees (directories, extents, free space) to aid both performance
+	  and scalability.
+
+	  Refer to the documentation at <http://oss.sgi.com/projects/xfs/>
+	  for complete details.  This implementation is on-disk compatible
+	  with the IRIX version of XFS.
+
+	  To compile this file system support as a module, choose M here: the
+	  module will be called xfs.  Be aware, however, that if the file
+	  system of your root partition is compiled as a module, you'll need
+	  to use an initial ramdisk (initrd) to boot.
+
+config XFS_QUOTA
+	bool "XFS Quota support"
+	depends on XFS_FS
+	select QUOTACTL
+	help
+	  If you say Y here, you will be able to set limits for disk usage on
+	  a per user and/or a per group basis under XFS.  XFS considers quota
+	  information as filesystem metadata and uses journaling to provide a
+	  higher level guarantee of consistency.  The on-disk data format for
+	  quota is also compatible with the IRIX version of XFS, allowing a
+	  filesystem to be migrated between Linux and IRIX without any need
+	  for conversion.
+
+	  If unsure, say N.  More comprehensive documentation can be found in
+	  README.quota in the xfsprogs package.  XFS quota can be used either
+	  with or without the generic quota support enabled (CONFIG_QUOTA) -
+	  they are completely independent subsystems.
+
+config XFS_POSIX_ACL
+	bool "XFS POSIX ACL support"
+	depends on XFS_FS
+	select FS_POSIX_ACL
+	help
+	  POSIX Access Control Lists (ACLs) support permissions for users and
+	  groups beyond the owner/group/world scheme.
+
+	  To learn more about Access Control Lists, visit the POSIX ACLs for
+	  Linux website <http://acl.bestbits.at/>.
+
+	  If you don't know what Access Control Lists are, say N.
+
+config XFS_RT
+	bool "XFS Realtime subvolume support"
+	depends on XFS_FS
+	help
+	  If you say Y here you will be able to mount and use XFS filesystems
+	  which contain a realtime subvolume.  The realtime subvolume is a
+	  separate area of disk space where only file data is stored.  It was
+	  originally designed to provide deterministic data rates suitable
+	  for media streaming applications, but is also useful as a generic
+	  mechanism for ensuring data and metadata/log I/Os are completely
+	  separated.  Regular file I/Os are isolated to a separate device
+	  from all other requests, and this can be done quite transparently
+	  to applications via the inherit-realtime directory inode flag.
+
+	  See the xfs man page in section 5 for additional information.
+
+	  If unsure, say N.
+
+config XFS_WARN
+	bool "XFS Verbose Warnings"
+	depends on XFS_FS && !XFS_DEBUG
+	help
+	  Say Y here to get an XFS build with many additional warnings.
+	  It converts ASSERT checks to WARN, so will log any out-of-bounds
+	  conditions that occur that would otherwise be missed. It is much
+	  lighter weight than XFS_DEBUG and does not modify algorithms and will
+	  not cause the kernel to panic on non-fatal errors.
+
+	  However, similar to XFS_DEBUG, it is only advisable to use this if you
+	  are debugging a particular problem.
+
+config XFS_DEBUG
+	bool "XFS Debugging support"
+	depends on XFS_FS
+	help
+	  Say Y here to get an XFS build with many debugging features,
+	  including ASSERT checks, function wrappers around macros,
+	  and extra sanity-checking functions in various code paths.
+
+	  Note that the resulting code will be HUGE and SLOW, and probably
+	  not useful unless you are debugging a particular problem.
+
+	  Say N unless you are an XFS developer, or you play one on TV.
