Anyway... to answer your direct question: all of that would have been
required anyway. In therms of build rules the overall patchset is
pretty much a lateral move from arch/x86/kernel/acpi/rm to
arch/x86/realmode/rm. That doesn't mean we couldn't do it
better/centralize/etc; however, none of this is new and would be a
separate change.
