It may have the unintended side # effect of sending local TLBIs when we explicitly need global # invalidations in this case. Thus breaking any nMMU user in a bad and # unpredictable way. # # Fix it by flushing first, before updating the 'copros' counter, so # that invalidations will be global. # # Fixes: 0cef77c7798a ("powerpc/64s/radix: flush remote CPUs out of single-threaded mm_cpumask") # Signed-off-by: Frederic Barrat <fbarrat@linux.ibm.com> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # Tested-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 cca19f0b684f4ed6aabf6ad07ae3e15e77bfd78a # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- allmodconfig # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
