    Steve came up with a patch that warned about problematic select
    only in a defconfig. It did not warn properly for all the problematic
    selects.
    I ran (as usual) out of time last time I looked :-(
    I would likely need a full day or two to come up with somthing,
    but these days finding an hour is not easy.
