* kconfig: KCONFIG_OVERWRITECONFIGRoman Zippel2006-06-09

* kconfig: add defconfig_list/module optionRoman Zippel2006-06-09
| | | | | | | | | | | | 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.

* kconfig: integrate split config into silentoldconfigRoman Zippel2006-06-09
| | | | | | | | | | | | | 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).

* kconfig: fix .config dependenciesRoman Zippel2006-06-09
| | | | | | | | | | | | | | | | | | | | | | 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.

* kbuild: fix make rpm for powerpcMike Wolf2006-06-08
| | | | | | | | | | | 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.

* kbuild: obj-dirs is calculated incorrectly if hostprogs-y is definedPavel Roskin2006-06-08
| | | | | | | | | | | | | | 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.

* [PATCH] kbuild: check SHT_REL sectionsAtsushi Nemoto2006-05-21
| | | | | | | | | | | | | | | | | 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.

To fix this the following was done: - let gen_initramfs.sh generate a list of files and directories included in the initramfs - gen_initramfs generate the gzipped cpio archive so we could simplify the kbuild file (Makefile) - utilising the kbuild infrastructure so when uid/gid root mapping changes the initramfs will be rebuild With this change we have a much more robust initramfs generation.

* [PATCH] x86_64: Basic reorder infrastructureArjan van de Ven2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch puts the infrastructure in place to allow for a reordering of functions based inside the vmlinux. The general idea is that it is possible to put all "common" functions into the first 2Mb of the code, so that they are covered by one TLB entry. This as opposed to the current situation where a typical vmlinux covers about 3.5Mb (on x86-64) and thus 2 TLB entries. This is done by enabling the -ffunction-sections flag in gcc, which puts each function in its own ELF section, so that the linker can then order them in a way defined by the linker script. As per previous discussions, Linus said he wanted a "static" list for this, eg a list provided by the kernel tarbal, so that most people have the same ordering at least. A script is provided to create this list based on readprofile(1) output. The included list is provisional, and entirely biased on my own testbox and me running a few kernel compiles and some other things. I think that to get to a better list we need to invite people to submit their own profiles, and somehow add those all up and base the final list on that. I'm willing to do that effort if this is ends up being the prefered approach. Such an effort probably needs to be repeated like once a year or so to adopt to the changing nature of the kernel. Made it a CONFIG with default n because it increases link times dramatically. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
