Hi Matthew,
I noticed that the commit 0b6b1bb28482 ("mm: rename
ARCH_ENABLE_THP_MIGRATION to ARCH_HAS_PMD_SOFTLEAVES") on linux-next
renames the config option ARCH_ENABLE_THP_MIGRATION, which is referred
to in this recent commit 04b177544a040 ("drm/pagemap: Guard
HPAGE_PMD_ORDER use with CONFIG_ARCH_ENABLE_THP_MIGRATION").You might want to have a look at that. Best regards, Lukas
