Subject: memory-hotplug: don't calculate vm_total_pages twice when rebuilding zonelists in online_pages()
From: Kent Liu <kent.liu@xxxxxxxxxxxxxxx>
If zonelist is required to be rebuilt in online_pages(), there is no need
to recalculate vm_total_pages in that function, as it has been updated in
the call build_all_zonelists().
