[PATCH] make oom killer points unsigned long

[PATCH] make oom killer points unsigned long

It seems a little unsafe to me to have oom killer badness points of type
int, when all the underlying objects are unsigned long.

I can't immediately think of a case where this matters much, but e.g.  a
long-running job or daemon on a 64 bit machine might lose it's bonus
because of that.
