This is to insert pgdat to its link. To be honest, I would like remove this pgdat link, and I posted patches to remove it for a long time ago to -mm.

But, it might have influence against performance for big NUMA box. So, I should check it. However, I'm very hard to access big NUMA box. Our machine is divided as small partitioned for test of each team inside of fujitsu every time. Sigh. :-(.
This is small lazy patch instead of them.
