asm-generic/page.h looks good.  I'll give it a shot.

I just changed this around a little bit so that only the architectures
that care see the prompt:

That at least consolidates the four architectures.  I guess I could move
them back, but some of the help text was _really_ similar and it all
seemed pretty redundant.

It wouldn't be hard to move it back, though.  That would certainly work.
