Oops sorry :!)
On 64bit kernel, the 16 'possible but not online' cpus are not on node 0, but balanced between two nodes.
cpu=0 node=1 cpu=1 node=0 cpu=2 node=1 cpu=3 node=0 cpu=4 node=1 cpu=5 node=0 cpu=6 node=1 cpu=7 node=0 cpu=8 node=1 cpu=9 node=0 cpu=10 node=1 cpu=11 node=0 cpu=12 node=1 cpu=13 node=0 cpu=14 node=1 cpu=15 node=0 cpu=16 node=0 cpu=17 node=1 cpu=18 node=0 cpu=19 node=1 cpu=20 node=0 cpu=21 node=1 cpu=22 node=0 cpu=23 node=1 cpu=24 node=0 cpu=25 node=1 cpu=26 node=0 cpu=27 node=1 cpu=28 node=0 cpu=29 node=1 cpu=30 node=0 cpu=31 node=1
