    mm: fault feedback #2 · 83c54070
    Nick Piggin authored
    This patch completes Linus's wish that the fault return codes be made into
    bit flags, which I agree makes everything nicer.  This requires requires
    all handle_mm_fault callers to be modified (possibly the modifications
    should go further and do things like fault accounting in handle_mm_fault --
    however that would be for another patch).
