Thus, remove the # unneeded initialization. # # Signed-off-by: Jason Wang # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20211220030243.603435-1-wangborong@cdjrlc.com # < /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 7773544e4027aa905e7f75752e3db619b473bd5c # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_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/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4311:warning: override: reassigning to symbol PPC_E500MC .config:4312:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/bitops.h:33, from /kisskb/src/include/linux/kernel.h:13, from /kisskb/src/include/linux/cpumask.h:10, 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/arch/powerpc/include/asm/kvm_ppc.h:15, from /kisskb/src/arch/powerpc/kvm/e500_emulate.c:12: /kisskb/src/arch/powerpc/include/asm/bitops.h: In function 'kvmppc_core_emulate_op_e500': /kisskb/src/arch/powerpc/include/asm/bitops.h:104:3: error: asm operand 2 probably doesn't match constraints [-Werror] 104 | asm volatile ( \ | ^~~ /kisskb/src/arch/powerpc/include/asm/bitops.h:126:1: note: in expansion of macro 'DEFINE_CLROP' 126 | DEFINE_CLROP(clear_bits, "") | ^~~~~~~~~~~~ /kisskb/src/arch/powerpc/include/asm/bitops.h:104:3: error: impossible constraint in 'asm' 104 | asm volatile ( \ | ^~~ /kisskb/src/arch/powerpc/include/asm/bitops.h:126:1: note: in expansion of macro 'DEFINE_CLROP' 126 | DEFINE_CLROP(clear_bits, "") | ^~~~~~~~~~~~ cc1: all warnings being treated as errors make[3]: *** [/kisskb/src/scripts/Makefile.build:288: arch/powerpc/kvm/e500_emulate.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.build:550: arch/powerpc/kvm] Error 2 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/kisskb/src/Makefile:1840: arch/powerpc] Error 2 make[1]: *** Waiting for unfinished jobs....
