    But I am guessing that neither you, nor Linus, regularly build MIPS
    kernels with GCC-4.5.x *and* jump label support enabled. So how would
    such semantic conflict ever be detected? I would expect the conflict to
    first occur when Linus pulls Ralf's tree.

    I don't expect anybody to magically fix such things, so whatever
    happens, I will test it and submit patches if required.
