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. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+config BINFMT_ELF
+ bool "Kernel support for ELF binaries"
+ depends on MMU && (BROKEN || !FRV)
+ default y
+ ---help---
+ ELF (Executable and Linkable Format) is a format for libraries and
+ executables used across different architectures and operating
+ systems. Saying Y here will enable your kernel to run ELF binaries
+ and enlarge it by about 13 KB. ELF support under Linux has now all
+ but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
+ because it is portable (this does *not* mean that you will be able
+ to run executables from different architectures or operating systems
+ however) and makes building run-time libraries very easy. Many new
+ executables are distributed solely in ELF format. You definitely
+ want to say Y here.
+
+ Information about ELF is contained in the ELF HOWTO available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ If you find that after upgrading from Linux kernel 1.2 and saying Y
+ here, you still can't run any ELF binaries (they just crash), then
+ you'll have to install the newest ELF runtime libraries, including
+ ld.so (check the file <file:Documentation/Changes> for location and
+ latest version).
+
+config COMPAT_BINFMT_ELF
+ bool

+config BINFMT_ELF_FDPIC
+ bool "Kernel support for FDPIC ELF binaries"
+ default y
+ depends on (FRV || BLACKFIN || (SUPERH32 && !MMU) || C6X)
+ help
+ ELF FDPIC binaries are based on ELF, but allow the individual load
+ segments of a binary to be located in memory independently of each
+ other. This makes this format ideal for use in environments where no
+ MMU is available as it still permits text segments to be shared,
+ even if data segments are not.
+
+ It is also possible to run FDPIC ELF binaries on MMU linux also.
+
+config CORE_DUMP_DEFAULT_ELF_HEADERS
+ bool "Write ELF core dumps with partial segments"
+ default y
+ depends on BINFMT_ELF && ELF_CORE
+ help
+ ELF core dump files describe each memory mapping of the crashed
+ process, and can contain or omit the memory contents of each one.
+ The contents of an unmodified text mapping are omitted by default.
+
+ For an unmodified text mapping of an ELF object, including just
+ the first page of the file in a core dump makes it possible to
+ identify the build ID bits in the file, without paying the i/o
+ cost and disk space to dump all the text. However, versions of
+ GDB before 6.7 are confused by ELF core dump files in this format.
+
+ The core dump behavior can be controlled per process using
+ the /proc/PID/coredump_filter pseudo-file; this setting is
+ inherited. See Documentation/filesystems/proc.txt for details.
+
+ This config option changes the default setting of coredump_filter
+ seen at boot time. If unsure, say Y.
+
+config BINFMT_SCRIPT
+ tristate "Kernel support for scripts starting with #!"
+ default y
+ help
+ Say Y here if you want to execute interpreted scripts starting with
+ #! followed by the path to an interpreter.
+
+ You can build this support as a module; however, until that module
+ gets loaded, you cannot run scripts. Thus, if you want to load this
+ module from an initramfs, the portion of the initramfs before loading
+ this module must consist of compiled binaries only.
+
+ Most systems will not boot if you say M or N here. If unsure, say Y.
+
+config BINFMT_FLAT

+
+config BINFMT_AOUT
+ tristate "Kernel support for a.out and ECOFF binaries"
+ depends on HAVE_AOUT
+ ---help---
+ A.out (Assembler.OUTput) is a set of formats for libraries and
+ executables used in the earliest versions of UNIX. Linux used
+ the a.out formats QMAGIC and ZMAGIC until they were replaced
+ with the ELF format.
+
+ The conversion to ELF started in 1995. This option is primarily
+ provided for historical interest and for the benefit of those
+ who need to run binaries from that era.
+
+ Most people should answer N here. If you think you may have
+ occasional use for this format, enable module support above
+ and answer M here to compile this support as a module called
+ binfmt_aout.
+
+ If any crucial components of your system (such as /sbin/init
+ or /lib/ld.so) are still in a.out format, you will have to
+ say Y here.
+
+config OSF4_COMPAT
+ bool "OSF/1 v4 readv/writev compatibility"
+ depends on ALPHA && BINFMT_AOUT
+ help
+ Say Y if you are using OSF/1 binaries (like Netscape and Acrobat)
+ with v4 shared libraries freely available from Compaq. If you're
+ going to use shared libraries from Tru64 version 5.0 or later, say N.
+
+config BINFMT_EM86
+ tristate "Kernel support for Linux/Intel ELF binaries"
+ depends on ALPHA
+ ---help---
+ Say Y here if you want to be able to execute Linux/Intel ELF
+ binaries just like native Alpha binaries on your Alpha machine. For
+ this to work, you need to have the emulator /usr/bin/em86 in place.
+
+ You can get the same functionality by saying N here and saying Y to
+ "Kernel support for MISC binaries".
+
+ You may answer M to compile the emulation support as a module and
+ later load the module when you want to use a Linux/Intel binary. The
+ module will be called binfmt_em86. If unsure, say Y.
+
+config BINFMT_MISC
+ tristate "Kernel support for MISC binaries"
+ ---help---
+ If you say Y here, it will be possible to plug wrapper-driven binary
+ formats into the kernel. You will like this especially when you use
+ programs that need an interpreter to run like Java, Python, .NET or
+ Emacs-Lisp. It's also useful if you often run DOS executables under
+ the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>). Once you have
+ registered such a binary class with the kernel, you can start one of
+ those programs simply by typing in its name at a shell prompt; Linux
+ will automatically feed it to the correct interpreter.
+
+ You can do other nice things, too. Read the file
+ <file:Documentation/binfmt_misc.txt> to learn how to use this
+ feature, <file:Documentation/java.txt> for information about how
+ to include Java support. and <file:Documentation/mono.txt> for
+ information about how to include Mono-based .NET support.
+
+ To use binfmt_misc, you will need to mount it:
+ mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
+
+ You may say M here for module support and later load the module when
+ you have use for it; the module is called binfmt_misc. If you
+ don't know what to answer at this point, say Y.
+
+config COREDUMP
+ bool "Enable core dump support" if EXPERT
+ default y
+ help
+ This option enables support for performing core dumps. You almost
+ certainly want to say Y here. Not necessary on systems that never
+ need debugging or only ever run flawless code.
