Hi Steve,

First bad commit (maybe != root cause):

tree:   git://git.samba.org/sfrench/cifs-2.6.git for-next
head:   c1abf13059571edd59d42d676ffe593fb987c019
commit: b4a8c8f8fa8b7b86bb62257fbb27e7bde58ac97e [3/4] cifs: rename fs/cifs directory to fs/smbfs_client
config: ia64-defconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 11.2.0
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 remote add cifs git://git.samba.org/sfrench/cifs-2.6.git
        git fetch --no-tags cifs for-next
        git checkout b4a8c8f8fa8b7b86bb62257fbb27e7bde58ac97e
        # save the attached .config to linux build tree
        COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-11.2.0 make.cross ARCH=ia64
