Hi Jeffrey,

[auto build test ERROR on v4.5-rc1]
[also build test ERROR on next-20160128]
[cannot apply to tip/x86/core]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

url: https://github.com/0day-ci/linux/commits/Jeffrey-Merkey/Add-hard-soft-lockup-debugger-entry-points/20160129-035852

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=m68k
