Currently, memory-failure can be enabled without migration. However, migration cannot be selected by user when memory-failure is enabled. Migration is very useful for soft_offline_page(), which may be triggered by correctable memory errors. Most of the anonymous or file-mapping faulty pages can be migrated to other healthy pages. Allow user to select MIGRATION if MEMORY_FAILURE is enabled. Also, select MIGRATION by default if MEMORY_FAILURE is enabled.
