[PATCH] wait_table and zonelist initializing for memory hotadd: update zonelists
In current code, zonelist is considered to be build once, no modification.
But MemoryHotplug can add new zone/pgdat. It must be updated.
This patch modifies build_all_zonelists(). By this, build_all_zonelist() can
reconfig pgdat's zonelists.
To update them safety, this patch use stop_machine_run(). Other cpus don't
touch among updating them by using it.
In old version (V2 of node hotadd), kernel updated them after zone
initialization. But present_page of its new zone is still 0, because
online_page() is not called yet at this time. Build_zonelists() checks
present_pages to find present zone. It was too early. So, I changed it after
online_pages().
