Hi Andrew,

It's probably a bug fix that unveils the link errors.

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head:   3248efff60b83f93dad704e98d80657285aa0780
commit: bbbfaae3a26dd9762187f0daac74889661a4f0dd [6909/7874] mm-oom-introduce-oom-reaper-fix-fix-2
config: tile-allnoconfig (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
        git checkout bbbfaae3a26dd9762187f0daac74889661a4f0dd
        # save the attached .config to linux build tree
        make.cross ARCH=tile 

All errors (new ones prefixed by >>):
