7ca8fe94aa92 is now in the mm-stable branch, which is is non-rebasing,
so this hash should be good.

Patches get moved from the rebasing mm-unstable to the non-rebasing
mm-stable when they're considered to be stabilized.

Ditto mm-hotfixes-unstable/mm-hotfixes-stable and
mm-nonmm-unstable/mm-nonmm-stable.
