commit: 1062fc45d1e93faefb93961f3be0a687f3f0e2e1 MIPS: Loongson64: Select SMP in Kconfig to avoid build error
date: 5 months ago
config: mips-randconfig-r011-20210301 (attached as .config)
compiler: clang version 13.0.0 (https://github.com/llvm/llvm-project b077d82b00d81934c7c27ac89dd8b0e7f448bded)
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 mips cross compiling tool for clang build
# apt-get install binutils-mips-linux-gnu
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1062fc45d1e93faefb93961f3be0a687f3f0e2e1
git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout 1062fc45d1e93faefb93961f3be0a687f3f0e2e1
