It's here in arch/x86_64/mm/init.c::show_mem():
for_each_online_pgdat(pgdat) {
for (i = 0; i < pgdat->node_spanned_pages; ++i) {
page = pfn_to_page(pgdat->node_start_pfn + i);
total++;
======> if (PageReserved(page))
reserved++;
else if (PageSwapCache(page))
cached++;
else if (page_count(page))
shared += page_count(page) - 1;
}
}
page is completely bogus (it's 0x0000000003480000)
