Thus the "attempt" in the # summary line. # # [ Note: in a small nod to "the profiling code can cause NUMA problems", # this also removes the "increment the last entry in the profiling array # on any unknown hits" logic. That would account any program counter in # a module to that single counter location, and might exacerbate any # NUMA cacheline bouncing issues ] # # Link: https://lore.kernel.org/all/CAHk-=wgs52BxT4Zjmjz8aNvHWKxf5_ThBY4bYL1Y6CTaNL2dTw@mail.gmail.com/ # Link: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git [1] # Cc: Thomas Gleixner <tglx@linutronix.de> # Cc: Tetsuo Handa <penguin-kernel@i-love.sakura.ne.jp> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 2accfdb7eff65f390c4308b0e9cb7c3fe48ad63c # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig # < make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/kernel/fork.c: In function '__do_sys_clone3': /kisskb/src/kernel/fork.c:3072:2: error: #warning clone3() entry point is missing, please fix [-Werror=cpp] 3072 \| #warning clone3() entry point is missing, please fix \| ^~~~~~~ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:244: kernel/fork.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:485: kernel] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/Makefile:1925: .] Error 2 make[1]: * [/kisskb/src/Makefile:224: __sub-make] Error 2 make: * [Makefile:224: __sub-make] Error 2 Command 'make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allmodconfig_sparc64-gcc13 # Build took: 0:17:28.994253
