[ARM] 3152/1: make various assembly local labels actually local (the rest)
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.
