     Subject: mm/Kconfig: make MEMORY_FAILURE select MIGRATION
has been removed from the -mm tree.  Its filename was

Subject: mm/Kconfig: make MEMORY_FAILURE select MIGRATION
Date: Thu, 13 Aug 2026 21:49:16 +0800

For embedded devices, lacking support for NUMA, memory hotplug/hotremove,
CMA and huge pages is a quite common scenario.  In this scenario, the
demand for contiguous physical memory allocation is very low.  To reduce
the kernel image size, some devices disable the compaction.  However,
their SoCs do support DDR ECC, meaning that memory-failure may be needed.

Migration is very useful for soft_offline_page() in memory-failure, which
may be triggered by correctable memory errors.  Most anonymous and
file-mapped faulty pages can be migrated to other healthy pages.

Currently, MEMORY_FAILURE does not explicitly select MIGRATION.  When
COMPACTION, MEMORY_HOTREMOVE, NUMA_MIGRATION and CMA are all disabled,
MEMORY_FAILURE can be enabled, but MIGRATION cannot be selected.

Make MEMORY_FAILURE select MIGRATION to handle this situation.
