Hi Krzysztof,

First bad commit (maybe != root cause):

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 61556703b610a104de324e4f061dc6cf7b218b46
commit: ea0c0ad6b6eb36726088991d97a55b99cae456d0 memory: Enable compile testing for most of the drivers
date: 6 months ago

wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross

git fetch --no-tags linus master
git checkout ea0c0ad6b6eb36726088991d97a55b99cae456d0
