I am sorry but I still do not understand why you consider this whack a
mole better then simply live with the fact that NUMA_NO_NODE is a
reality and that using the full cpu mask is a reasonable answer to that.

Because it doesn't make physical sense. A device _cannot_ be local to
all CPUs in a NUMA system.

While it cannot be local to all CPUs, it can be at a uniform (equal) distance
to each CPU node, can't it?
