    Wouldn't this mean that we try to set up the NMI stuff regardless of
    forcing the timer ? I can imagine a flaky system where somebody needs to
    avoid going near that stuff.

    timer_init() making sure to set all fields seems reasonable to me. Or
    oprofile_init() could grab ->backtrace, memset the structure, then
    replace ->backtrace...
