commit: d2706a31db9d55bf0c4c6d2c60beb02b4459805e [2/6] lockdep: Change hardirq{s_enabled,_context} to per-cpu variables
config: s390-randconfig-r006-20200528 (attached as .config)
compiler: clang version 11.0.0 (https://github.com/llvm/llvm-project 2d068e534f1671459e1b135852c1b3c10502e929)
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# install s390 cross compiling tool for clang build
# apt-get install binutils-s390-linux-gnu
git checkout d2706a31db9d55bf0c4c6d2c60beb02b4459805e
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross ARCH=s390
If you fix the issue, kindly add following tag as appropriate
