Split out preparatory changes in a new preceding patch # - Added -fasynchronous-unwind-tables to CC flags. # # v6: # - Added missing prototypes in asm/vdso/gettimeofday.h for __c_kernel_ functions. # - Using STACK_FRAME_OVERHEAD instead of INT_FRAME_SIZE # - Rebased on powerpc/merge as of 7 Apr 2020 # - Fixed build failure with gcc 9 # - Added a patch to create asm/vdso/processor.h and more cpu_relax() in it # < /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 7fd5004bbade1bf77fbb7e73b2b5a9eda1e892ea # < make -s -j 24 ARCH=powerpc O=/kisskb/build/chleroy_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 40x/walnut_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/chleroy_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/chleroy_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/chleroy_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:804: Warning: invalid register expression INFO: Uncompressed kernel (size 0x514660) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Completed OK # rm -rf /kisskb/build/chleroy_40x_walnut_defconfig_powerpc-gcc5 # Build took: 0:00:50.170446
