Indeed, it would. The main reason I let it this way was to keep it closer to
the i386 paravirt code (which is the main reason I'm sending this
patches - to pave the way for the x86_64 one), but they seem to be
getting an argument for store_tr in current tree. So there's no arguable
advantage on doing it my way at all ;-)

Thanks
