Hi Randy,

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

tree:   git://git.cmpxchg.org/linux-mmotm.git master
head:   03590d39c08e0f2969871a5efcf27a366c1e8c60
commit: cffa367bb8abe4c1424e93e345c7d63844d1c5db [19/222] sh: fix multiple function definition build errors
config: sh-allmodconfig (attached as .config)
compiler: sh4-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout cffa367bb8abe4c1424e93e345c7d63844d1c5db
        # save the attached .config to linux build tree
        GCC_VERSION=7.2.0 make.cross ARCH=sh 

All errors (new ones prefixed by >>):

>> arch/sh/kernel/cpu/sh2/clock-sh7619.o:(.data+0x1c): undefined reference to `followparent_recalc'
