[PATCH] lib/string.c cleanup: remove pointless register keyword
Removes a few pointless register keywords. register is merely a compiler
hint that access to the variable should be optimized, but gcc (3.3.6 in my
case) generates the exact same code with and without the keyword, and even
if gcc did something different with register present I think it is doubtful
we would want to optimize access to these variables - especially since this
is generic library code and there are supposed to be optimized versions in
asm/ for anything that really matters speed wise.
(akpm: iirc, keyword register is a gcc no-op unless using -O0)
