    drm/i915: extract object active state flushing code · 30dfebf3

    Both busy_ioctl and the new wait_ioct need to do the same dance (or at
    least should). Some slight changes:
    - busy_ioctl now unconditionally checks for olr. Before emitting a
      require flush would have prevent the olr check and hence required a
      second call to the busy ioctl to really emit the request.
    - the timeout wait now also retires request. Not really required for
      abi-reasons, but makes a notch more sense imo.
    
    I've tested this by pimping the i-g-t test some more and also checking
    the polling behviour of the wait_rendering_timeout ioctl versus what
    busy_ioctl returns.
    
    v2: Too many people complained about unplug, new color is
    flush_active.
    
    v3: Kill the comment about the unplug moniker.
    
    v4: s/un-active/inactive/
