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/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-ld --version # < git log --format=%s --max-count=1 92edf8df0ff2ae86cc632eeca0e651fd8431d40d # < make -s -j 120 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- defconfig # make -s -j 120 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-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/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:187:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:337:21: note: 'pdeo' was declared here /kisskb/src/kernel/trace/trace_dynevent.c: In function 'create_dyn_event': /kisskb/src/kernel/trace/trace_dynevent.c:89:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1435:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_setup_act': /kisskb/src/drivers/s390/scsi/zfcp_erp.c:262:2: warning: 'erp_action' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1845:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1755:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_s390-defconfig_s390x # Build took: 0:04:10.532465
