Drop the barrier from # syscall_dotrace, because that syscall number comes from the # kernel.] # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 f0e26956bcea49f03a88e87d784a0a3b53760cb0 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc837x_mds_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/mpc837x_mds_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc837x_mds_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x532398) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.17.0-rc1-gf0e2695 Created: Wed Apr 18 00:37:51 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2677797 Bytes = 2615.04 kB = 2.55 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_mpc837x_mds_defconfig_powerpc-5.3 # Build took: 0:00:18.887603
