Long way to say 'valid'.

SMPConfiguration and CpuTopology have named fields so we could drop the
'expect: ...' comment line and instead do

 {
  /* no configuration provided */ 
  .config = { .has_cpus = F, .has_maxcpus = F, ... },
  .valid = T,
  .expect = { .sockets = 1, .cores = 1, ... },
 }, {
  ...
 }

which may be easier to maintain. OTOH, the concise form this approach has
is also nice. I don't think you should need the casts in the assignments
though.
