    Thanks for reporting.

    I tried to reproduce with above steps, while failed with below message.
    Later I got a s390x machine to reproduce the failure, and made a fix in
    below patch.

    [root@dell-pem620-01 linux]# COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-12.3.0 ~/bin/make.cross W=1 O=build_dir ARCH=s390 olddefconfig

    Subject: [PATCH] s390: mm: fix building error when converting to
    GENERIC_IOREMAP
    Content-type: text/plain

    We should always include <asm/io.h> in ARCH, but not <asm-generic/io.h>
    directly. Otherwise, macro defined by ARCH won't be seen and could cause
    building error.
