Commits on Jan 6, 2023

  1. (draft) Remove SMP deactivation on big machines 

    This might be a bit controversial but
1. AMD offers 48/67/64 (true) core systems already (Milan, (*)), up to
   96 cores/CPU soon (Genoa),
2. Intel sells a few Xeon CPUs with > cores (**),
and we shouldn't artificially limit core utilization on such sytems.
