That's not how it looks like here:

[ 0.369572] NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.
[ 0.377957] x86: Booting SMP configuration:
[ 0.382294] .... node #0, CPUs: #1 #2 #3
[ 0.428340] .... node #1, CPUs: #4 #5 #6 #7
[ 0.564304] .... node #2, CPUs: #8 #9 #10 #11

[ 0.836819] x86: Booted up 4 nodes, 16 CPUs
[ 0.841487] smpboot: Total of 16 processors activated (73944.72 BogoMIPS)

and:
