commit: 2f428da8a77487d943ab9c255518832fdd3953cc [12/22] drm/i915: Respect DP++ adaptor TMDS clock limit
config: i386-defconfig (attached as .config)
compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430
reproduce:
        git checkout 2f428da8a77487d943ab9c255518832fdd3953cc
        # save the attached .config to linux build tree
        make ARCH=i386 

Note: the drm-intel/drm-intel-nightly HEAD 0ab3c45d270cc4dce75993a749dc11d12f8746cb builds fine.
      It only hurts bisectibility.
