Subject: [PATCH] memory-hotplug: build zonelists when offlining pages

online_pages() does build_all_zonelists() and zone_pcp_update(), I think
offline_pages() should do it too.

When the zone has no memory to allocate, remove it from other nodes'
zonelists.  zone_batchsize() depends on zone's present pages, if zone's
present pages are changed, zone's pcp should be updated.
