commit: efcd1418868bc7be0eb22a57497ac20eeb831ff1 [2081/2680] drm/amdkcl: Test whether memalloc_nofs_save() and memalloc_nofs_restore() functions are available
config: i386-allyesconfig (attached as .config)
compiler: gcc-7 (Debian 7.5.0-3) 7.5.0
reproduce:
        git checkout efcd1418868bc7be0eb22a57497ac20eeb831ff1
        # save the attached .config to linux build tree
        make ARCH=i386
