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/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 2accfdb7eff65f390c4308b0e9cb7c3fe48ad63c # make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig CONFIG_SPI_STM32_QSPI=n # < make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:14987:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:14991:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:14993:warning: override: reassigning to symbol UML_NET_SLIP .config:14998:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/lib/iomap.c:156:5: error: no previous prototype for ‘ioread64_lo_hi’ [-Werror=missing-prototypes] 156 \| u64 ioread64_lo_hi(const void __iomem addr) \| ^~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:163:5: error: no previous prototype for ‘ioread64_hi_lo’ [-Werror=missing-prototypes] 163 \| u64 ioread64_hi_lo(const void __iomem addr) \| ^~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:170:5: error: no previous prototype for ‘ioread64be_lo_hi’ [-Werror=missing-prototypes] 170 \| u64 ioread64be_lo_hi(const void __iomem addr) \| ^~~~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:178:5: error: no previous prototype for ‘ioread64be_hi_lo’ [-Werror=missing-prototypes] 178 \| u64 ioread64be_hi_lo(const void __iomem addr) \| ^~~~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:264:6: error: no previous prototype for ‘iowrite64_lo_hi’ [-Werror=missing-prototypes] 264 \| void iowrite64_lo_hi(u64 val, void __iomem addr) \| ^~~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:272:6: error: no previous prototype for ‘iowrite64_hi_lo’ [-Werror=missing-prototypes] 272 \| void iowrite64_hi_lo(u64 val, void __iomem addr) \| ^~~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:280:6: error: no previous prototype for ‘iowrite64be_lo_hi’ [-Werror=missing-prototypes] 280 \| void iowrite64be_lo_hi(u64 val, void __iomem addr) \| ^~~~~~~~~~~~~~~~~ /kisskb/src/lib/iomap.c:288:6: error: no previous prototype for ‘iowrite64be_hi_lo’ [-Werror=missing-prototypes] 288 \| void iowrite64be_hi_lo(u64 val, void __iomem addr) \| ^~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:244: lib/iomap.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:485: lib] 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=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allyesconfig_um-x86_64-gcc12 # Build took: 0:19:41.397764
