It turns out, if I disable "Support for paging of anonymous memory
(swap)" --- SWAP
the CONFIG_MIGRATION will disappear from the .config
the mm/mempolicy.c may need some #if CONFIG_MIRGRATION to comment out
these calling.

Could you try this patch:

It works but there are some typo
+static inline int isolate_lru_pages(struct page *p) { return -ENOSYS; }
+static inline int putback_lru_pages(struct list_head *) { return 0; }
+static inline int migrate_pages(struct list_head *l, struct list_head *t,
+ struct list_head *moved, struct list_head *failed) { return -ENOSYS; }
===>
+static inline int isolate_lru_page(struct page *p) { return -ENOSYS; }
+static inline int putback_lru_pages(struct list_head *l) { return 0; }
+static inline int migrate_pages(struct list_head *l, struct list_head *t,
+ struct list_head *moved, struct list_head *failed) { return -ENOSYS; }
So the CONFIG_MIGRATION depends on CONFIG_NUMA and CONFIG_SWAP?

Yes. Maybe this will change in the future if we can find another way to
preserve the anonymous mappings.
