Much quieter ... but perhaps a little too quiet?
Is this what you want?  Now the console output looks like this:

CPU0 attaching sched-domain:
 domain 0: span 0-15 level CPU
  groups:
CPU1 attaching sched-domain:
 domain 0: span 0-15 level CPU
  groups:
CPU2 attaching sched-domain:
 domain 0: span 0-15 level CPU
  groups:
 ...

instead of the original:

CPU0 attaching sched-domain:
 domain 0: span 0-15 level CPU
  groups: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
CPU1 attaching sched-domain:
 domain 0: span 0-15 level CPU
  groups: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0
CPU2 attaching sched-domain:
 domain 0: span 0-15 level CPU
  groups: 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1
 ...

Either we don't need the empty "groups:" line, or we should
still list the cpus in the group?  I'm not really sure what
information you are trying to convey here.
