But let's keep some code quality standards here, and not # accept outrageously bad code. # # Link: https://lore.kernel.org/lkml/CAHk-=wgV9toS7GU3KmNpj8hCS9SeF+A0voHS8F275_mgLhL4Lw@mail.gmail.com/ # Cc: Andy Lutomirski <luto@kernel.org> # Cc: Thomas Gleixner <tglx@linutronix.de> # Cc: Peter Zijlstra (Intel) <peterz@infradead.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 bb5a93aaf25261321db0c499cde7da6ee9d8b164 # < make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig KCONFIG_SEED=0x36F610B2 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=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 # < make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:5441:warning: override: reassigning to symbol STANDALONE .config:5442:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/drivers/mailbox/imx-mailbox.c:638:12: warning: 'imx_mu_runtime_resume' defined but not used [-Wunused-function] static int imx_mu_runtime_resume(struct device dev) ^~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/mailbox/imx-mailbox.c:629:12: warning: 'imx_mu_runtime_suspend' defined but not used [-Wunused-function] static int imx_mu_runtime_suspend(struct device dev) ^~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/mailbox/imx-mailbox.c:611:12: warning: 'imx_mu_resume_noirq' defined but not used [-Wunused-function] static int imx_mu_resume_noirq(struct device dev) ^~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/mailbox/imx-mailbox.c:601:12: warning: 'imx_mu_suspend_noirq' defined but not used [-Wunused-function] static int imx_mu_suspend_noirq(struct device dev) ^~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 # Build took: 0:04:19.911195
