Raw Normal View History

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!

[ARM] 3151/1: make various assembly local labels actually local (io-*.S) Patch from Nicolas Pitre For assembly labels to actually be local they must start with ".L" and not only "." otherwise they still remain visible in the final link and clutter kallsyms needlessly, and possibly make for unclear symbolic backtrace. This patch simply inserts a"L" where appropriate. The code itself is unchanged. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
