The only open question is whether there is a better way of getting there. Perhaps with less configuration options in the first place? We are heading towards a future where so many systems will be NUMA that there would seem to be little benefit in keeping ACPI_NUMA separate from ACPI ... but perhaps we aren't quite there yet.
