Hi Thomas, This applies on top of mips-next or Linus' tree, so you may need to rebase mips-fixes before taking it. It's not for mips-next as it should go into this cycle as a [hot]fix. I haven't added any "Fixes:" tag since these warnings is a result of merging several sets and of certain build configurations that almost couldn't be tested separately.
