Up to this point we tried to keep patchset bisectable, but next patches are going to change how core of THP refcounting work. It would be beneficial to split the change into several patches and make it more reviewable. Unfortunately, I don't see how we can achieve that while keeping THP working. Let's hide THP under CONFIG_BROKEN for now and bring it back when new refcounting get established. Signed-off-by: Kirill A.
