2006-10-11[PATCH] Add CONFIG_HEADERS_CHECK option to automatically run 'make ↵David Woodhouse
headers_check' In order to encourage people to notice when they break the exported headers, add a config option which automatically runs the sanity checks when building vmlinux. That way, those who use allyesconfig will notice failures.

2006-10-04[PATCH] Fix spurious error on TAGS target when missing defconfigDavid Gibson
Not all architectures have a file named 'defconfig' (e.g. powerpc). However the make TAGS and make tags targets search such files for tags, causing an error message when they don't exist. This patch addresses the problem by instructing xargs not to run the tags program if there are no matching files.

2006-09-16[PATCH] headers_check: use a different default directoryDavid Woodhouse
`make headers_check' wants to go and write stuff in /lib/modules, which requires root, whic is unfortunate. In fact, there's no _particular_ reason for headers_install to put it there either -- it can go into a subdirectory of the build tree in both cases. It's not intended to go directly into /usr/include, which is why we didn't put it there -- and we certainly don't want people screwing around with symlinking to it. It's for distributors to take away and do stuff with, so leaving it in $(objtree) is fine, even in the headers_install case. I picked $(objtree)/usr/include but I have no _particular_ preference for that; it just seemed reasonable.

2006-07-03kbuild: introduce utsrelease.hSam Ravnborg
include/linux/version.h contained both actual KERNEL version and UTS_RELEASE that contains a subset from git SHA1 for when kernel was compiled as part of a git repository. This had the unfortunate side-effect that all files including version.h would be recompiled when some git changes was made due to changes SHA1. Split it out so we keep independent parts in separate files. Also update checkversion.pl script to no longer check for UTS_RELEASE. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-07-01kbuild: fix ia64 breakage after introducing make -rRSam Ravnborg
kbuild used $¤(*F to get filename of target without extension. This was used in several places all over kbuild, but introducing make -rR broke his for all cases where we specified full path to target/prerequsite. It is assumed that make -rR disables old style suffix-rules which is why is suddenly failed. ia64 was impacted by this change because several div* routines in arch/ia64/lib are build using explicit paths and then kbuild failed. Thanks to David Mosberger-Tang <David.Mosberger@acm.org> for an explanation what was the root-cause and for testing on ia64.

2006-06-24kbuild: adding symbols in Kconfig and defconfig to TAGSMasatake YAMATO
I'm using TAGS generated from "make TAGS" to read the kernel source code. When I met a ifdef block #ifdef CONFIG_FOO ... #endif in the soruce code I would like to know the meaning CONFIG_FOO to decide whether I should read inside the ifdef block or not. meaning CONFIG_FOO is well documented in Kconfig. So it is nice if I can jump to CONFIG_FOO entry in Kconfig from "#ifdef CONFIG_FOO" with the tag jump. Here is the patch to add symbols in Kconfig and defconfig to TAGS in "make TAGS" operation.

2006-06-24kbuild: support for %.symtypes filesAndreas Gruenbacher
Here is a patch that adds a new -T option to genksyms for generating dumps of the type definition that makes up the symbol version hashes. This allows to trace modversion changes back to what caused them. The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes. This can save a tremendous amount of time. Dump the types that make up modversions Signed-off-by: Andreas Gruenbacher <agruen@suse.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-06-24kbuild: add option for stripping modules while installing themTheodore Ts'o
Add option for stripping modules while installing them. This function adds support for stripping modules while they are being installed. CONFIG_DEBUG_KERNEL (which will probably become more popular as developers use kdump) causes the size of the installed modules to grow by a factor of 9 or so. Some kernel package systems solve this problem by stripping the debug information from /lib/modules after running "make modules_install", but that may not work for people who are installing directly into /lib/modules --- root partitions that were sized to handle 16 megs worth of modules may not be quite so happy with 145 megs of modules, so the "make modules_install" never succeeds. This patch allows such users to request modules_install to strip the modules as they are installed. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
