to
add_active_range with different code.  So I've changed the code into a
common implementation.

The other subtle issue fixed by this patch was calling add_active_range in
count_node_pages before granule aligning is performed.  We were lucky with
16MB granules but not so with 64MB granules.  count_node_pages has reserved
regions filtered out and as a consequence linked kernel text and data
aren't covered by calls to count_node_pages.  So linked kernel regions
wasn't reported to add_active_regions.  This resulted in free_initmem
causing numerous bad_page reports.  This won't occur with this patch
because now all known memory regions are reported by
register_active_ranges.
