commit: 680273879d125d644831b8de42c66576e6290378 [3/4] drm/i915: Move parking-while-active warning to intel_engines_park()
config: i386-randconfig-x003-201744 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        git checkout 680273879d125d644831b8de42c66576e6290378
        # save the attached .config to linux build tree
        make ARCH=i386 

Note: the drm-intel/for-linux-next HEAD 3265124a2d3744d789ede58452ab6f8a9b454be8 builds fine.
      It only hurts bisectibility.
