Since it looks like # it got dropped inadvertently by commit 3cdfcbfd32b9 ("powerpc: Change # analyse_instr so it doesn't modify regs"). # # A key detail is that analyse_instr() will never recognise lwsync or # ptesync on 32-bit (because of the existing ifdef), and as a result # emulate_update_regs() should never be called with an op specifying # either of those on 32-bit. So removing them from emulate_update_regs() # should be a nop in terms of runtime behaviour. # # Fixes: 3cdfcbfd32b9 ("powerpc: Change analyse_instr so it doesn't modify regs") # Cc: stable@vger.kernel.org # v4.14+ # Suggested-by: Arnd Bergmann <arnd@arndb.de> # Signed-off-by: Anders Roxell <anders.roxell@linaro.org> # [mpe: Add last paragraph of change log mentioning analyse_instr() details] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20220211005113.1361436-1-anders.roxell@linaro.org # < /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 fe663df7825811358531dc2e8a52d9eaa5e3515e # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_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-fixes_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-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4322:warning: override: reassigning to symbol PPC_E500MC .config:4323:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_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:22, 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:1831: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs....
