See http://git.kernel.org/?p=linux/kernel/git/sam/kbuild.git;a=summary Everything are targeted for next merge window. section mismatch kbuild: make better section mismatch reports on i386, arm and mips kbuild: The .paravirtprobe section is obsolete, so modpost doesn't need to handle it kbuild: ignore section mismatch warnings originating from .note section kbuild: refactor code in modpost to improve maintainability kbuild: warn about references from .init.text to .exit.text kbuild: remove hardcoded apic_es7000 from modpost kbuild: refactor code in modpost kbuild: remove hardcoded _logo names from modpost kbuild: suppress modpost warnings for references from the .toc section as used by powerpc kbuild: whitelist references from variables named _timer to .init.text Several changes to either improve reporting - or to ignore false positives. In particular modpost now check for and warn about references from .init.text to .exit.text This check caugth several real bugs - which for the most part are already fixed in upstream. modpost now does a better job finding the symbols using addend - this works for me but had caused troubles in the past. If modpost suddenly bails out with a segmentation violation this may the the culprint. In addition some trivial code refactoring was done to improve maintainability of modpost. kconfig: use POSIX equality test in check-lxdialog.sh Bugfix. scripts: Make cleanfile/cleanpatch warn about long lines Improved so we all adhere to 80 lines (in)sanity kbuild: avoid environment to set variables used by kbuild I had a report that a user tried to do: EXTRA_CFLAGS=FOO make fs/nfs/ This is not supposed to impact the build so make sure it does not. kbuild: add support for reading stdin with gen_init_cpio kbuild: add support for squashing uid/gid in gen_initramfs_list.sh initramfs improvements kbuild: asm-offsets.h is now cleaned with O=.. builds Bugfix kbuild: document cc-fullversion kbuild: New 'cc-fullversion' macro powerpc: Refuse to build 64-bit with GCC-4.2.0 and CONFIG_MODULES Add and use cc-fullversion to obtain exact gcc version See documentation in Documentation/kbuild/makefiles.txt What's next? -> davem has requested to add a new section used for code modifying support. The actual section name to use needs to be sorted out. -> A few cygwin specific changes may hit kbuild - to allow the kernel to be built using cygwin on a windoze box. -> A few trivial kconfig changes are pending. Needs to review them before they are ready. -> A speed-up of headers_check is in the works. Got stalled but will look into it soon. The check goes down to ~3 sec on my not-so-fast machine -> If I get really bored I may start a 'cleaning up all vmlinux.lds files' round. If someone would help out here it would be appreciated. These change will then be merged via the arch-maintaines and not really kbuild stuff.. Sam
