Should we really report the maximum supported number of CPUs or the actual
number?
Several processor manuals state that it is the number of physically present CPUs
that is reported (-1 of course).
In that case, the following would do?
mpp->frep = 0x004f0002 | ((mpp->nb_cpus - 1)<< 8);
mpp->veni = VENI;
mpp->pint = 0x00000000;
