commit: 5321a620f6eb25e0990612f2e93670851415f344 [19/20] lockdep: Change
hardirq{s_enabled,_context} to per-cpu variables
config: arm-defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (GCC) 9.3.0
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
git checkout 5321a620f6eb25e0990612f2e93670851415f344
# save the attached .config to linux build tree
