    SubjectRe: [PATCH 2/3] blackfin: make-bf561/coreb.c explicitly non-modular
    Hi Paul,

    [auto build test ERROR on linus/master]
    [also build test ERROR on v4.9-rc3 next-20161028]
    [if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
    [Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
    [Check https://git-scm.com/docs/git-format-patch for more information]

    url: https://github.com/0day-ci/linux/commits/Paul-Gortmaker/lightnvm-make-core-c-explicitly-non-modular/20161030-044459
    config: blackfin-CM-BF561_defconfig (attached as .config)
    compiler: bfin-uclinux-gcc (GCC) 6.2.0
    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
    # save the attached .config to linux build tree
    make.cross ARCH=blackfin

    All error/warnings (new ones prefixed by >>):
