reset_zone_present_pages() has been removed by the recently-queued
revert-mm-fix-up-zone-present-pages.patch, so I dropped that hunk.

We still have

akpm:/usr/src/25> grep N_HIGH_MEMORY mm/page_alloc.c
        [N_HIGH_MEMORY] = { { [0] = 1UL } },
                        node_set_state(nid, N_HIGH_MEMORY);
                        if (N_NORMAL_MEMORY != N_HIGH_MEMORY &&

which I hope is correct.  Can you please check it?
