True. Someone needs to go through discontig and make it work right with a
!NUMA configuration. Many pieces of the core code assume that there will
be no node on a !NUMA config today. I guess that was different in ages
past.
Maybe we should make DISCONTIG broken under !NUMA until that time?
Tejon was working on getting rid of DISCONTIG. SPARSEMEM is the favored
alternative today. So we could potentially change the arches to use SPARSE
configs in the !NUMA case.
