So what you're saying is that we need to distinguish between number of
possible CPUs and how many we allow for a given type of emulation? It
seems to me that using MAX_CPUS to be the maximum possible for an
architecture is fair and we should then maybe put it into the machine
description to set the upper limit for actual runtime ones?
