It means moving patches 2,4,5 from the above (with their fixups) from mm-unstable to mm-hotfixes-unstable so they are on track to mainline before 6.9. A quick local rebase of mm-unstable with reordering said patches to the front (v6.9-rc4) suggests this is possible without causing conflicts, and the intermediate result compiles, at least.
