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>
