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
[ 0.700242] .... node #3, CPUs: #12 #13 #14 #15
[ 0.836819] x86: Booted up 4 nodes, 16 CPUs
[ 0.841487] smpboot: Total of 16 processors activated (73944.72 BogoMIPS)

and:

[ 0.304732] x86: Booting SMP configuration:
[ 0.326682] NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.
[ 0.309034] .... node #0, CPUs: #1 #2 #3 #4 #5 #6 #7
[ 0.417810] .... node #1, CPUs: #8 #9 #10 #11 #12 #13 #14 #15
[ 0.608563] x86: Booted up 2 nodes, 16 CPUs
[ 0.613169] smpboot: Total of 16 processors activated (89598.99 BogoMIPS)

Thanks,
