I don't mind the divergence in this area if the libc folks are ok with

Yes, though that's basically the same thing - the difference is
basically just that x86 uses their custom arch_prctl() thing and we use
a regular prctl(), there's nothing conceptual going on like there is
here.  I don't really mind either, it's just something where I'd
anticipate pushback.
