    Ahem, but let me note before somebody else does: it isn't interrupt context,
    it is normal process context - while an interrupt can ignore most of the
    thread_info fields, a normal process has to worry about all 9. To be on the
    safe side, the first 8 need to be copied into and out of the ndis stack, with
    preempt disabled until after the stack switch.
