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)
