Description

Problem Description
======================
On the same target, when we run intel-x86-32 system, we only can find out one numa node. But when we run intel-x86-64 system, we can find 2 nodes.

Log on intel-x86-32:
root@Remley-EP-Ivy-Refresh-1:~# numactl --hardware
available: 1 nodes (0)
node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47
