Yup, this looks like the correct fix to me. I came out to the same
result when I merged. I've also build tested for booke.

Linus, I've done a trial merge and pushed it out to the next-resolved
branch on my tree (pull req below). You can either use my previous
pull request and fix it up yourself or use this one:

The following changes since commit 8bea8672edfca7ec5f661cafb218f1205863b343:
