Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

kbuild: filter away debug symbols from kernel symbols Andi Kleen <andi@firstfloor.org> reported that he saw a lot of symbols like this: 0000000000000b24 N DW.aio.h.903a6d92.2 0000000000000bce N DW.task_io_accounting.h.8d8de327.0 0000000000000bec N DW.hrtimer.h.c23659c6.0 in his System.map / kallsyms output. Simple solution is to skip all debugging symbols (they are marked 'N'). Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Paulo Marques <pmarques@grupopie.com>

mksysmap: update comment about __crc_* Since commit 7b4537199a4a ("kbuild: link symbol CRCs at final link, removing CONFIG_MODULE_REL_CRCS"), __crc_* symbols never become absolute. Keep ignoring __crc_*, but update the comment. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

kallsyms: drop duplicated ignore patterns from kallsyms.c Now that kallsyms.c parses the output from mksysmap, some symbols have already been dropped. Move comments to scripts/mksysmap. Also, make the grep command readable. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

kallsyms: ignore __kstrtab_* and __kstrtabns_* symbols Every EXPORT_SYMBOL creates __kstrtab_* and __kstrtabns_*, which consumes 15-20% of the kallsyms entries. For example, on the system built from the x86_64 defconfig, $ cat /proc/kallsyms | wc 129527 388581 5685465 $ cat /proc/kallsyms | grep __kstrtab | wc 23489 70467 1187932 We already ignore __crc_* symbols populated by EXPORT_SYMBOL, so it should be fine to ignore __kstrtab_* and __kstrtabns_* as well. This makes vmlinux a bit smaller. $ size vmlinux.before vmlinux.after text data bss dec hex filename 22785374 8559694 1413328 32758396 1f3da7c vmlinux.before 22785374 8137806 1413328 32336508 1ed6a7c vmlinux.after Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
