Hi Jon,

[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]

config: sparc-allmodconfig (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 abb68976e3057f70babddaf71802ed126d0297bc
        # save the attached .config to linux build tree
        make.cross ARCH=sparc
