given that some of Movable users can be built as modules, shouldn't
at least some of those symbols be exported via EXPORT_SYMBOL?

__ClearPageMovable() is under CONFIG_MIGRATION in include/linux/migrate.h,
but zsmalloc checks for CONFIG_COMPACTION.
can we have stub declarations of movable functions for !CONFIG_MIGRATION builds?
otherwise the users (zsmalloc, for example) have to do things like
static void reset_page(...

Those functions aim for VM compaction so driver shouldn't use it.
Only driver should be aware of are __SetPageMovable and __CleraPageMova...
