Ok, so you're saying we need to revert 1ba9bf0a and 7764/1. I couldn't
find a commit corresponding to this one, however there is a commit
labelled 7763/1 from you that touch the same area (18d7f152). Are these
the commits that need to be reverted (and then reapplied for 3.11) ?

Russell, Arnd, Olof, who should revert this patch, and through which
tree?

Thanks,
Maxime
