For that to work with syscall wrappers, the prototype of the # syscall must have the argument split so that the wrapper macro properly # unpacks the arguments from pt_regs. # # The fanotify_mark() syscall is one such syscall, which already has a # split prototype, guarded behind ARCH_SPLIT_ARG64. # # So select ARCH_SPLIT_ARG64 to get that prototype and fix fanotify_mark() # on 32-bit kernels with syscall wrappers. # # Note also that fanotify_mark() is the only usage of ARCH_SPLIT_ARG64. # # Fixes: 7e92e01b7245 ("powerpc: Provide syscall wrapper") # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20221101034852.2340319-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 02a771c9a68a9f08cce4ec5e324fb1bc4dce7202 # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # Added to kconfig CONFIG_CRASH_DUMP=y # Added to kconfig CONFIG_FA_DUMP=y # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4350:warning: override: reassigning to symbol CRASH_DUMP .config:4351:warning: override: reassigning to symbol FA_DUMP # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc5 # Build took: 0:02:08.885473
