We will soon reclaim the part of the vmemmap region that covers VA space
that is not addressable by the hardware. To avoid confusion, ensure that
the 'vmemmap start' marker points at the start of the region that is
actually being used for the struct page array, rather than the start of
the region we set aside for it at build time.
