most architectures (pretty much everyone but like x86/x86_64/s390)
export empty asm/page.h headers ... considering how useless these are,
why bother exporting them at all ? clearly userspace is unable to
rely on it across architectures, so by making it available to the two
most common (x86/x86_64), applications crop up that build "fine" on
them but fail just about everywhere else

It should not be exported to userspace at all. Care to submit a patch?

I think we can kill off <asm/elf.h> too -- the only interesting parts
are in <asm/auxvec.h>, aren't they?
