    Subject[PATCH 09/10] uml: comment about cast build fix
    From: Paolo 'Blaisorblade' Giarrusso <>

    Explain why the casting we do to silence this warning is indeed safe.

    It is because the field we're casting from, though being 64-bit wide, was filled
    with a pointer in first place by ourselves.
