Yang Shi fe53ca5427 mm: use early_pfn_to_nid in page_ext_init ... page_ext_init() checks suitable pages with pfn_to_nid(), but pfn_to_nid() depends on memmap which will not be setup fully until page_alloc_init_late() is done. Use early_pfn_to_nid() instead of pfn_to_nid() so that page extension could be still used early even though CONFIG_ DEFERRED_STRUCT_PAGE_INIT is enabled and catch early page allocation call sites. Suggested by Joonsoo Kim [1], this fix basically undoes the change introduced by commit b8f1a75d61 ("mm: call page_ext_init() after all struct pages are initialized") and fixes the same problem with a better approach.
