Dietmar/Vincent,
Do you think it makes sense to enable the driver on ARM64 now?
Or you think it is better to delay it and once the feature is stable
ARM ecosystem can enable it?

It's always better to support all arch by default, unless something is
missing which is not the case here.

ARM64 testing is obviously missed.

But the cpumask is already available not like if you need to create a new one
