* Basic implementation of 'make headers_check'David Woodhouse2006-06-18
| | | | | | | | 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>
* Basic implementation of 'make headers_install'David Woodhouse2006-06-18
| | | | | | | | | | | | | 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>
* [PATCH] kbuild: fix modpost segfault for 64bit mipsel kernelAtsushi Nemoto2006-05-21
| | | | | | | | | | | | | | Here is an updated r_info layout fix. Please apply "check SHT_REL sections" patch before this. 64bit mips has different r_info layout. This patch fixes modpost segfault for 64bit little endian mips kernel.

* [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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | initramfs.cpio.gz being build in usr/ and included in the kernel was not rebuild when the included files changed. 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kbuild system takes advantage of an incorrect behavior in GNU make.
