Oh, I got the point now.
Somehow I missed that we were freeing up the memory when CONFIG_MEMORY_HOTPLUG
was not in place.

So your patch makes sense to me now, sorry.

Since my patchset [1] + cleanup patch [2] remove almost all __paginginit,
leaving only pgdat_init_internals() and zone_init_internals(), I think
it would be great if you base your patch on top of that.
Or since the patchset has some cleanups already, I could add your patch
into it (as we did for the zone_to/set_nid() patch) and send a v6 with it.

What do you think?
