After this patch it goes up to 118 million. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 de8a34242c88473ee615f66a7ded095f094e708e # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/npiggin_x86_64-allnoconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/npiggin_x86_64-allnoconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 48 ARCH=x86_64 O=/kisskb/build/npiggin_x86_64-allnoconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 48 ARCH=x86_64 O=/kisskb/build/npiggin_x86_64-allnoconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- arch/x86/entry/thunk_64.o: warning: objtool: missing symbol table make[3]: * [/kisskb/src/scripts/Makefile.build:361: arch/x86/entry/thunk_64.o] Error 1 make[3]: * Deleting file 'arch/x86/entry/thunk_64.o' make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:497: arch/x86/entry] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1756: arch/x86] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:185: __sub-make] Error 2 Command 'make -s -j 48 ARCH=x86_64 O=/kisskb/build/npiggin_x86_64-allnoconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/npiggin_x86_64-allnoconfig_x86_64-gcc11 # Build took: 0:00:38.719529
