commit: c60f169202c7643991a8b4bfeea60e06843d5b5a arch/mn10300/kernel/fpu-nofpu.c: needs asm/elf.h
date: 3 months ago
config: mn10300-allnoconfig (attached as .config)
compiler: am33_2.0-linux-gcc (GCC) 4.9.0
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
git checkout c60f169202c7643991a8b4bfeea60e06843d5b5a
# save the attached .config to linux build tree
