    3.3. I think I tried reverting 00f49e5729af602deb559b0cf293a00b625e8636 and
    it failed. Then I locally commented out the WARN_ONCE in the functions which
    got rid of that, but we still get a 'suspicious RCU usage' warning when
    running powertop. I gave up after that, since it all goes away if we disable
    the debugging options and you have fixes queued for 3.4.
