Why? It initializes a single page, deferred_init_pages() initializes many.

There's no __init_reserved_page_zone(). Currently init_reserved_page()
detects the zone of the page and calls __init_single_page(), so essentially
it initializes one struct page.

And we __SetPageReserved() in reserve_bootmem_region() after call to
init_reseved_page() because pages there are indeed reserved.
