Why does this have the crappy cputime scaling overflow code, when we
had a long thread about how to do it right *without* any 64-bit
divides, including a quality-tested patch?
This still has the garbage "div64_u64_rem()" crap which actually SLOWS
DOWN 32-bit code even when not used (becuse it makes "div64_u64()"
calculate it even when unnecessary.
WTF happened here? I and others spent efforts so that we wouldn't need
this kind of crap.
