commit: 12aa2587388de6697fd2e585ae6a90f70249540b [10017/14131] sched/cpuacct: Use __this_cpu_add() instead of this_cpu_ptr()
config: i386-randconfig-a012-20200601 (attached as .config)

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 i386 cross compiling tool for clang build
# apt-get install binutils-i386-linux-gnu
git checkout 12aa2587388de6697fd2e585ae6a90f70249540b
