Log message:
Take the "package" into account when calculating the "smt" ID on modern
AMD CPUs. Avoids knocking out too many processor threads on for example
the AMD Ryzen Threadtipper 2990WX which apparently consists of 4 separate
dies with 8 cores each. Note that the "package" ID really is a "die" ID
here.
