Why a rebase? The folio change comes via another tree (unfortunately not
Andrews tree, I wish we would have a single MM tree for MM patches).

@Andrew, the last mail I received was

+ mm-huge_memory-remove-stale-locking-logic-from-__split_huge_pmd.patch
added to -mm tree

The patch shows up in mmotm as

#[merged]mm-huge_memory-remove-stale-locking-logic-from-__split_huge_pmd.patch

... which shouldn't be true.
