[PATCH] mm: use early_pfn_to_nid in register_page_bootmem_info_node

by Yang Shi

register_page_bootmem_info_node() is invoked in mem_init(), so it will be called before page_alloc_init_late() if CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled. But, pfn_to_nid() depends on memmap which won't be fully setup until page_alloc_init_late() is done, so replace pfn_to_nid() by early_pfn_to_nid().

[PATCH] mm: use early_pfn_to_nid in page_ext_init

by Yang Shi

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 b8f1a75d61d8405a753380c6fb17ba84a5603cd4 ("mm: call page_ext_init() after all struct pages are initialized") and fixes the same problem with a better approach.
