But we know now that we only expect to see # the software count cache flush enabled if the other options are false. # # So split the two cases, which simplifies the logic and fixes the bug. # We were also missing a space before "(hardware accelerated)". # # The result is we see one of: # # Mitigation: Indirect branch serialisation (kernel only) # Mitigation: Indirect branch cache disabled # Mitigation: Software count cache flush # Mitigation: Software count cache flush (hardware accelerated) # # Fixes: ee13cb249fab ("powerpc/64s: Add support for software count cache flush") # Cc: stable@vger.kernel.org # v4.19+ # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Reviewed-by: Michael Neuling <mikey@neuling.org> # Reviewed-by: Diana Craciun <diana.craciun@nxp.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 92edf8df0ff2ae86cc632eeca0e651fd8431d40d # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # Added to kconfig CONFIG_PPC_SPLPAR=n # yes \n \| make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] /kisskb/src/net/netfilter/nf_nat_masquerade.c:15:21: warning: 'masq_refcnt6' defined but not used [-Wunused-variable] static unsigned int masq_refcnt6 __read_mostly; ^ /kisskb/src/net/sunrpc/xprtsock.c: In function 'xs_stream_data_receive': /kisskb/src/net/sunrpc/xprtsock.c:529:9: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] return ret < 0 ? ret : read; ^ /kisskb/src/net/sunrpc/xprtsock.c:499:10: note: 'ret' was declared here ssize_t ret; ^ /kisskb/src/net/sunrpc/xprtsock.c:498:15: warning: 'read' may be used uninitialized in this function [-Wmaybe-uninitialized] size_t want, read; ^ Completed OK # rm -rf /kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc5 # Build took: 0:02:43.681936
