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-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 1619b69edce14c4a4665fa8ff4c587dcc77202a9 # < make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig # 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 # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig # < make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_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 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:7265:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:7267:warning: override: reassigning to symbol GCC_PLUGINS # make -s -j 32 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- arch/x86/crypto/sm4-aesni-avx-asm_64.o: warning: objtool: sm4_aesni_avx_crypt8()+0x8: sibling call from callable instruction with modified stack frame /kisskb/src/drivers/gpu/drm/radeon/radeon_object.c: In function 'radeon_bo_create': /kisskb/src/drivers/gpu/drm/radeon/radeon_object.c:207:2: warning: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Wcpp] 207 \| #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance \ \| ^~~~~~~ /kisskb/src/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function 'amdgpu_bo_support_uswc': /kisskb/src/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:493:2: warning: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Wcpp] 493 \| #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance \ \| ^~~~~~~ In file included from /kisskb/src/include/linux/string.h:262, from /kisskb/src/include/linux/bitmap.h:10, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/smp.h:13, from /kisskb/src/include/linux/lockdep.h:14, from /kisskb/src/include/linux/mutex.h:17, from /kisskb/src/include/linux/kernfs.h:12, from /kisskb/src/include/linux/sysfs.h:16, from /kisskb/src/include/linux/kobject.h:20, from /kisskb/src/include/linux/of.h:17, from /kisskb/src/include/linux/irqdomain.h:35, from /kisskb/src/include/linux/acpi.h:13, from /kisskb/src/drivers/platform/x86/lg-laptop.c:10: In function 'strlen', inlined from 'acpi_add' at /kisskb/src/drivers/platform/x86/lg-laptop.c:658:6: /kisskb/src/include/linux/fortify-string.h:25:33: warning: argument 1 null where non-null expected [-Wnonnull] 25 \| #define __underlying_strlen __builtin_strlen \| ^ /kisskb/src/include/linux/fortify-string.h:60:24: note: in expansion of macro '__underlying_strlen' 60 \| return __underlying_strlen(p);
