Just an FYI, this conflicts with my patch:
https://lore.kernel.org/lkml/20230311003855.645684-6-opendmb@gmail.com/
So it would work better for me if it was folded into your "grand move"
(assuming that refers to your patch 4) and init_cma_reserved_pageblock()
could be retained as a wrapper there in my patch if we want to still
keep set_pageblock_migratetype() out of the common CMA code.
