No, but I have CC'ed him now.

It seems only i386 and amd64 have hooks for smp_topology:

/usr/src/sys# grep -R smp_topology *
amd64/amd64/mp_machdep.c:struct cpu_top *smp_topology;
i386/i386/mp_machdep.c:struct cpu_top *smp_topology;
i386/i386/mp_machdep.c: /* Build the smp_topology map. */
i386/i386/mp_machdep.c: smp_topology = &mp_top;
kern/sched_ule.c:       if (smp_topology == NULL) {
kern/sched_ule.c:               for (i = 0; i < smp_topology->ct_count; i++) {
kern/sched_ule.c:                       cg = &smp_topology->ct_group[i];
kern/sched_ule.c:               ksg_maxid = smp_topology->ct_count - 1;
sys/smp.h:extern struct cpu_top *smp_topology;
