That # means the lack of AT_BASE_PLATFORM is a user-visible artifact of the # fact that the kernel is using DT CPU features, which we don't want. # # So set it in the DT CPU features code also. # # This results in eg: # $ LD_SHOW_AUXV=1 /bin/true \| grep "AT_.*PLATFORM" # AT_PLATFORM: power9 # AT_BASE_PLATFORM:power9 # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 e4b79900222b8cccd4da4a7a89581f0e1b764ed2 # < make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # Added to kconfig CONFIG_CRASH_DUMP=y # Added to kconfig CONFIG_FA_DUMP=y # yes \n \| make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: modpost: Found 2 section mismatch(es).
