3. If we add flag to memblock, we can mark different memory. And I remember
    you mentioned before that we can use memblock to reserve local node data
    for node-life-cycle data, like vmemmap, pagetable.

    So are you doing the similar work now ?

No, i did not start it yet.


    If not, I think I can merge it into mine, and push a new patch-set with
    hot-add, hot-remove code modified to support putting vmemmap, pagetable,
    pgdat, page_cgroup, ..., on local node.

Need to have it separated with moving_zone.

1. rework memblock to keep alive all the way for hotplug usage.
2. put pagetable and vmemap on the local node range with help of memblock.


OK，thanks for the comments. I'll merge it into my work and post an RFC 
patch-set soon.

Thanks. :)
