Consolidate binfmt choices in Kconfig
PATCH 1/1 Consolidate binfmt choices in Kconfig

It's very repetitive, so to give a flavour for it, here's i386, m68knommu and fs/Kconfig.binfmt. I rewrote the BINFMT_AOUT helptext to bring it into this decade.
Comments welcomed; I'll send it to Linus tomorrow if I don't hear anything.

Linux used the - a.out formats QMAGIC and ZMAGIC until they were replaced with the - ELF format. - - As more and more programs are converted to ELF, the use for a.out - will gradually diminish. If you disable this option it will reduce - your kernel by one page. This is not much and by itself does not - warrant removing support. However its removal is a good idea if you - wish to ensure that absolutely none of your programs will use this - older executable format. If you don't know what to answer at this - point then answer Y. If someone told you "You need a kernel with - QMAGIC support" then you'll have to say Y here. You may answer M to - compile a.out support as a module and later load the module when you - want to use a program or library in a.out format. The module will be - called binfmt_aout. Saying M or N here is dangerous though, - because some crucial programs on your system might still be in A.OUT - format. - -config BINFMT_ELF - tristate "Kernel support for ELF binaries" - ---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). - - If you want to compile this as a module ( = code which can be - inserted in and removed from the running kernel whenever you want), - say M here and read <file:Documentation/modules.txt>. The module - will be called binfmt_elf. Saying M or N here is dangerous because - some crucial programs on your system might be in ELF format. - -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 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, and <file:Documentation/java.txt> for information about how - to include Java support. - - You must say Y to "/proc file system support" (CONFIG_PROC_FS) to - use this part of the kernel. - - 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. +source "fs/Kconfig.binfmt" endmenu

Shouldn't that just be:
bool "Enable ZFLAT support"
as the config bits take care of indentation now?
