Issue in kswapd daemon initilisation

[naveen yadav]

Dear all,

when I run cat /proc/zoneinfo on my ARM target. i got two nodes.
Node 0, zone   Normal
  pages free     39642
        min      338
        low      422
        high     507
        scanned  0 (aa: 0 ia: 0 af: 0 if: 0)
        spanned  43520
        present  43180
Node 1, zone   Normal
  pages free     21822
        min      170
        low      212
        high     255
        scanned  0 (aa: 0 ia: 0 af: 0 if: 0)
        spanned  22016
        present  21844

But when I check PS, I found that
root         0 SW<  [kswapd0] is running, So here is my question .

1. why there is no kswapd demon for another node.?
If I need to enable, how can I do.
2. I check on config option ARCH_POPULATES_NODE_MAP option is disable in ARM.

Thanks
