Not necessarily a good idea but how about...
static int bad_range(struct zone *zone, struct page *page)
{
unsigned long start_pfn;
unsigned long spanned_pages;
do {
start_pfn = zone->zone_start_pfn;
spanned_pages = zone->spanned_pages;
while (unlikely(start_pfn != zone->zone_start_pfn));
if (page_to_pfn(page) >= start_pfn + spanned_pages;
return 1;
}
