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
git remote add hch-block git://git.infradead.org/users/hch/block.git
git fetch --no-tags hch-block scsi-ioctl
git checkout 075e28806125ae286114e55557067e340f30a93a
# save the attached .config to linux build tree
