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/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 fe663df7825811358531dc2e8a52d9eaa5e3515e # < make -s -j 120 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # < make -s -j 120 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 120 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 120 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- warning: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum warning: LSE atomics not supported by binutils Completed OK # rm -rf /kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 # Build took: 0:01:50.926871
