commit: 48a95280236f1251065b24e29b417a63951bf224 [76/87] x86/PCI: VMD: Add quirk for AER
to ignore source ID
config: alpha-defconfig (attached as .config)
compiler: alpha-linux-gcc (GCC) 7.5.0
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 48a95280236f1251065b24e29b417a63951bf224
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-7.5.0 make.cross ARCH=alpha
