Thanks Paul-san.
I also have another issue around here.
(Kswapd doesn't run on memory less node now. It should run when

I would like to merge them like following if you don't mind.

Fix kswapd doesn't run when memory is added on memory-less-node.
Fix compile error of zone->node when CONFIG_NUMA is off.
