Please could you always put fixes at the beginning of a set as it makes it easier to back port them. It think this one is simple enough that it is worth applying to the stable kernels. (naturally I could do that anyway as the rebase is trivial, so I'm just encouraging good practice by asking you to do it in v3!)
