2006-06-24kbuild: export-symbol usage report generatorRam Pai
The following patch provides the ability to generate a report of (1) All the exported symbols and their in-kernel-module usage count (2) For each module, lists the modules and their exported symbols, on which it depends. the report can be generated by executing: perl scripts/export_report The tool warns if the modules are not build using MODVERSIONING.

2006-06-24kbuild: fix make -rR breakageSam Ravnborg
make failed to supply the filename when using make -rR and using $(*F) to get target filename without extension. This bug was not reproduceable in small scale but using: $(basename $(notdir $@)) fixes it with same functionality. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-06-18Basic implementation of 'make headers_check'David Woodhouse
Based on the 'headers_install' target, this performs a basic sanity check on the exported headers -- so far only checking that they do not include any other headers which aren't selected for import, but easily extendable. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-06-18Basic implementation of 'make headers_install'David Woodhouse
This adds a make target which exports a subset of headers which contain definitions which are useful for system libraries and tools. It uses the BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses sed to remove markers like __user. Based on an original implementation by Arnd Bergmann <arnd@arndb.de> Hacked about by David Woodhouse <dwmw2@infradead.org> Reviewed and cleaned up by Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-06-17kbuild: append git revision for all untagged commitsUwe Zeisberger
adds revision suffix for untagged commits that are reachable from a tag I'm bisecting and don't get the -g...... suffix. The reason is, that git name-rev --tags HEAD returns e.g. HEAD tags/v2.6.17-rc1^0~1067 which is currently good enough for setlocalversion to skip the suffix. This introduces a dependecy to grep -E, which should be fine.

2006-06-09kbuild: check license compatibility when building modulesSam Ravnborg
Modules that uses GPL symbols can no longer be build with kbuild, the build will fail during the modpost step. When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol then warn during modpost so author are actually notified. The actual license compatibility check is shared with the kernel to make sure it is in sync.

2006-06-09kconfig: add defconfig_list/module optionRoman Zippel
This makes it possible to change two options which were hardcoded sofar. 1. Any symbol can now take the role of CONFIG_MODULES 2. The more useful option is to change the list of default file names, which kconfig uses to load the base configuration if .config isn't available.

2006-06-09kconfig: integrate split config into silentoldconfigRoman Zippel
Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

2006-06-09kconfig: fix .config dependenciesRoman Zippel
This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

2006-06-09kconfig: improve config load/save outputRoman Zippel
During loading special case the first common case (.config), be silent about it and otherwise mark it as a change that requires saving. Instead output that the file has been changed. IOW if conf does nothing (special), it's silent. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-06-08kbuild: fix make rpm for powerpcMike Wolf
The default target for most powerpc platforms is zImage. The zImage however is in arch/powerpc/boot and the mkspec script was set up to get the kernel from the top level of the kernel tree. This patch copies vmlinux to arch/powerpc/boot and then copies the kernel to the tmp directory so the rpm can be made.

2006-06-08kbuild: obj-dirs is calculated incorrectly if hostprogs-y is definedPavel Roskin
When Makefile.host is included, $(obj-dirs) is subjected to the addprefix operation for the second time. Prefix only needs to be added to the newly added directories, but not to those that came from Makefile.lib. This causes the build system to create unneeded empty directories in the build tree when building in a separate directory. For instance, lib/lib/zlib_inflate is created in the build tree.

2006-05-21[PATCH] kbuild: check SHT_REL sectionsAtsushi Nemoto
I found that modpost can not detect section mismatch on mips and i386. On mips64, the modpost (with r_info layout fix) can detect it. The current modpst only checks SHT_RELA section but I suppose SHT_REL section should be checked also. This patch does not contain r_info layout fix. I'll post an updated r_info layout fix on next mail. Check SHT_REL sections as like as SHT_RELA sections to detect section mismatch.

Darren Jenkins <darrenrjenkins@gmail.com> pointed out a number of false positives where we referenced variables from a _driver variable. Fix it by check for that pattern and ignore it. Randy.Dunlap <rdunlap@xenotime.net> pointed out a similar set of warnings for a number of scsi drivers. In scsi world they misname their variables *_template or *_sht so add these to list of variables that may have references to .init.text with no warning. Randy.Dunlap <rdunlap@xenotime.net> also pointed out a scsi driver with many references to .exit.text from .rodata.
