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 a5dde5b54c02a2b1f839939ee89aa69caca3e02c # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_taishan_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/taishan_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_taishan_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x493898) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.16.0-rc4-ga5dde5b Created: Mon Apr 2 00:25:04 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2237745 Bytes = 2185.30 kB = 2.13 MB Load Address: 00500000 Entry Point: 005010fc Completed OK # rm -rf /kisskb/build/powerpc-next_44x_taishan_defconfig_powerpc-5.3 # Build took: 0:00:33.043326
