mm: init: report on last-nid information stored in page->flags
Answering the question "how much space remains in the page->flags" is
time-consuming. mminit_loglevel can help answer the question but it
does not take last_nid information into account. This patch corrects it
and while there it corrects the messages related to page flag usage,
pgshifts and node/zone id. When applied the relevant output looks
something like this but will depend on the kernel configuration.
mminit::pageflags_layout_widths Section 0 Node 9 Zone 2 Lastnid 9 Flags 25
mminit::pageflags_layout_shifts Section 19 Node 9 Zone 2 Lastnid 9
mminit::pageflags_layout_pgshifts Section 0 Node 55 Zone 53 Lastnid 44
mminit::pageflags_layout_nodezoneid Node/Zone ID: 64 -> 53
mminit::pageflags_layout_usage location: 64 -> 44 layout 44 -> 25 unused 25 -> 0 page-flags
