We can now print gfp_flags more human-readable. Make use of this in

Thanks.
Although I've always been curious about the usefulness of these out of
memory calls in the first place. They are obviously for debugging, but
have they actually helped to diagnose anything?
Uh no idea, maybe other SL*B maintainers have more experience. But what
did prompt me to write this patch is that I've recently have actually
seen the output of those in some (presumably linux-mm) thread.
