    Hi Luc,

    First bad commit (maybe != root cause):

    tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
    head: 7ddb58cb0ecae8e8b6181d736a87667cc9ab8389
    commit: e5fc436f06eef54ef512ea55a9db8eb9f2e76959 sparse: use static inline for __chk_{user,io}_ptr()
    date: 1 year, 2 months ago
    config: sh-randconfig-s032-20211104 (attached as .config)
    compiler: sh4-linux-gcc (GCC) 11.2.0
    reproduce:
    wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
    chmod +x ~/bin/make.cross
    # apt-get install sparse
