Subject: update N_HIGH_MEMORY node state for memory hotadd
From: Lee Schermerhorn <Lee.Schermerhorn@xxxxxx>
Setting N_HIGH_MEMORY node state in free_area_init_nodes() works for memory
present at boot time, but not for hot-added memory. Update the
N_HIGH_MEMORY node state in online_pages(), if we've added pages to this
node, before rebuilding zonelists.
