That's exactly what's implemented. If module, tile, die are not
advertised, then you end up with:

        N   threads
        N/2 cores
        1   module
        1   tile
        1   die

in a package because the bits occupied by module, tile and die are
exactly 0.

But from a conceptual and consistency point of view they exist, no?
