Note the "/* TODO: how to report? */" comment in the code: we definitely
_want_ to get users to see the warning and report it. It means the
kernel is giving contradictory information, and hwloc just happened to
take the first one and not the other.
Brad, could you post the output of the hwloc-gather-topology script from
hwloc? That's permit to know why the warning shows up.
