commit: cec08ed70d3d5209368a435fed278ae667117a0c [1860/2084] mm, printk: introduce new format string for flags
config: frv-defconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout cec08ed70d3d5209368a435fed278ae667117a0c
        # save the attached .config to linux build tree
