There is, on some hardware, a requirement that only specific processors
may service specific devices due to interrupt controller dispatching,
these are usually tied together as nodes and it'd be a lot easier
determining interrupt domain participants if we didn't have to deal with
arbitrary cpu masks but had a fixed group of processors and hence could
figure out which node they all belonged to.
