But it's not # needed for assembly files. # # The minimal fix is to move the addition to BOOT_CFLAGS of -include # compiler_attributes.h until after we've copied BOOT_CFLAGS into # BOOT_AFLAGS. That avoids including compiler_attributes.h for asm files, # but makes no other change to BOOT_CFLAGS or BOOT_AFLAGS. # # Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> # Debugged-by: Linus Torvalds <torvalds@linux-foundation.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Tested-by: Guenter Roeck <linux@roeck-us.net> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 1619b69edce14c4a4665fa8ff4c587dcc77202a9 # < make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/arch/s390/kernel/syscall.c: In function '__do_syscall': /kisskb/src/arch/s390/kernel/syscall.c:168:1: error: '__do_syscall' uses dynamic stack allocation [-Werror] } ^ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:277: arch/s390/kernel/syscall.o] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:540: arch/s390/kernel] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1868: arch/s390] Error 2 make[1]: * Waiting for unfinished jobs.... /kisskb/src/drivers/gpu/drm/rockchip/cdn-dp-core.c:1126:12: error: 'cdn_dp_resume' defined but not used [-Werror=unused-function] static int cdn_dp_resume(struct device dev) ^~~~~~~~~~~~~ cc1: all warnings being treated as errors make[5]: [/kisskb/src/scripts/Makefile.build:277: drivers/gpu/drm/rockchip/cdn-dp-core.o] Error 1 make[4]: * [/kisskb/src/scripts/Makefile.build:540: drivers/gpu/drm/rockchip] Error 2 make[4]: *** Waiting for unfinished jobs.... /kisskb/src/drivers/spi/spi-tegra20-slink.c:1200:12: error: 'tegra_slink_runtime_resume' defined but not used [-Werror=unused-function] static int tegra_slink_runtime_resume(struct device dev) ^~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/spi/spi-tegra20-slink.c:1188:12: error: 'tegra_slink_runtime_suspend' defined but not used [-Werror=unused-function] static int tegra_slink_runtime_suspend(struct device dev) ^~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:277: drivers/spi/spi-tegra20-slink.o] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:540: drivers/spi] Error 2 make[2]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:540: drivers/gpu/drm] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:540: drivers/gpu] Error 2 make[1]: * [/kisskb/src/Makefile:1868: drivers] Error 2 make: * [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_s390-allmodconfig_s390x-gcc8 # Build took: 0:08:28.237263
