kernel was fine, and most user land apps were fine as well.

Userland should really not have to deal with garbage like this.

And because it quietly works just fine on x86-64, nothing makes
sure that applications will universally get this right anyways.

Better to align things properly and magically all of these issues
simply disappear.
