Hi LABBE,

[auto build test WARNING on net/master -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

config: tile-allyesconfig (attached as .config)
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
        # save the attached .config to linux build tree
        make.cross ARCH=tile
