hwloc already reads access0/initiators/ node symlinks (mostly useful for
finding which CPUs are local to kmem dax devices). If I understand
correctly the changes you propose, we would get an empty list of CPUs in
the access0/initiators/ nodes? If it only occurs on platforms with GI
(when are those coming to market?), I'd say it's not a big deal for us,
we'll manage to have users upgrade their hwloc.
