The code was just # being silly and odd, and it should never have cared about signed vs # unsigned characters in the first place, since what it is testing is not # four "characters", but four bytes. # # And the way to compare four bytes is by using "memcmp()". # # Which compilers will know to just turn into a single 32-bit compare with # a constant, as long as you don't have crazy debug options enabled. # # Link: https://lore.kernel.org/lkml/20210927094123.576521-1-arnd@kernel.org/ # Cc: Arnd Bergmann # Cc: Hans de Goede # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9b3b353ef330e20bc2d99bf3165cc044cff26a09 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=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_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:5094:warning: override: reassigning to symbol STANDALONE .config:5098:warning: override: reassigning to symbol PPC64 .config:5099:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:5101:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:5106:warning: override: reassigning to symbol UBSAN # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c: In function 'dc_fpu_begin': /kisskb/src/drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/dc_fpu.c:97:4: error: implicit declaration of function 'enable_kernel_altivec'; did you mean 'enable_kernel_vsx'?
