commit: 76aefbddf9ff2cd227b9efa6e9b9d60ea1b9d387 [79/92] drm/amdgpu: add all the components for si into Makefile/kconfig v3
config: microblaze-allmodconfig (attached as .config)
compiler: microblaze-linux-gcc (GCC) 4.9.0
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 76aefbddf9ff2cd227b9efa6e9b9d60ea1b9d387
        # save the attached .config to linux build tree
        make.cross ARCH=microblaze 

Note: the radeon-alex/drm-next-4.8-wip-si HEAD a34f9def0cb7b66d510d6aff215c465e050767bf builds fine.
      It only hurts bisectibility.
