The original pSeries machine was limited to 32 CPUs, more or less
arbitrarily.  Particularly when we get SMT KVM guests it will be
pretty easy to exceed this.  Therefore, raise the max number of CPUs
in a pseries machine guest to 256.
Are the 256 limited by technical limits or arbitrary as well? :)
Still arbitrary, just bigger.

Can't we set it to the real, technical limit then?
