Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+config BINFMT_ELF
+ bool "Kernel support for ELF binaries"
+ depends on MMU
+ 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 BINFMT_ELF_FDPIC
+ bool "Kernel support for FDPIC ELF binaries"
+ default y
+ depends on FRV
+ 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 BINFMT_FLAT
+ tristate "Kernel support for flat binaries"
+ depends on !MMU || SUPERH
+ help
+ Support uClinux FLAT format binaries.
+
+config BINFMT_ZFLAT

+ help
+ Support FLAT format compressed binaries
+
+config BINFMT_SHARED_FLAT
+ bool "Enable shared FLAT support"
+ depends on BINFMT_FLAT
+ help
+ Support FLAT shared libraries
+
+config BINFMT_AOUT
+ tristate "Kernel support for a.out and ECOFF binaries"
+ depends on (X86 && !X86_64) || ALPHA || ARM || M68K || SPARC32
+ ---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_SOM
+ tristate "Kernel support for SOM binaries"
+ depends on PARISC && HPUX
+ help
+ SOM is a binary executable format inherited from HP/UX. Say
+ Y here to be able to load and execute SOM binaries directly.
+
+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.
