Nor do I see consistency in the way of passing # CONFIG options. # # decompress.c references CONFIG_KERNEL_GZIP and CONFIG_KERNEL_XZ, which # are passed via the command line. # # serial.c includes autoconf.h to reference a couple of CONFIG options, # but this is fragile because we often forget to include "autoconf.h" # from source files. # # In fact, it is already broken. # # ppc_asm.h references CONFIG_PPC_8xx, but utils.S is not given any way # to access CONFIG options. So, CONFIG_PPC_8xx is never defined here. # # Pass $(LINUXINCLUDE) to make sure CONFIG options are accessible from # all .c and .S files in arch/powerpc/boot/. # # I also removed the -traditional flag to make include/linux/kconfig.h # work. This flag makes the preprocessor imitate the behavior of the # pre-standard C compiler, but I do not understand why it is necessary. # # Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190705100144.28785-2-yamada.masahiro@socionext.com # < /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 b0b9f351fd616a01eea7c8d44e798db5a122a005 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # Added to kconfig CONFIG_NUMA=n # yes \n \| make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1658:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1633:6: note: 'oldval' was declared here int oldval, ret; ^ WARNING: vmlinux.o(.text+0x31fc): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
