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

Thanks, I saw some discussion on a linux-next merge conflict about this.
I think I can just do this in DRM to avoid the conflict + work with and
without 0b6b1bb28482.
-#if IS_ENABLED(CONFIG_ARCH_ENABLE_THP_MIGRATION)
+#if IS_ENABLED(CONFIG_PGTABLE_HAS_HUGE_LEAVES)
#define DRM_PAGEMAP_PMD_ORDER HPAGE_PMD_ORDER
#else
#define DRM_PAGEMAP_PMD_ORDER (-1)
Need to look at linux-next or core MM branches to confirm before I
post anything though to confirm.
