head: 8124c8a6b35386f73523d27eacb71b5364a68c4c
commit: ea29b20a828511de3348334e529a3d046a180416 init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
date: 3 months ago
config: s390-randconfig-r014-20210531 (attached as .config)
compiler: clang version 13.0.0 (https://github.com/llvm/llvm-project bc6799f2f79f0ae87e9f1ebf9d25ba799fbd25a9)
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-s390x-linux-gnu
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit...
git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout ea29b20a828511de3348334e529a3d046a180416
