However, the commit missed updating the offset used while # tearing down the ftrace stack when ftrace is disabled. Fix the same. # # In addition, the commit missed saving the correct stack pointer in # pt_regs. Update the same. # # Fixes: 41a506ef71eb ("powerpc/ftrace: Create a dummy stackframe to fix stack unwind") # Cc: stable@vger.kernel.org # v6.5+ # Signed-off-by: Naveen N Rao # Signed-off-by: Michael Ellerman # Link: https://msgid.link/20231130065947.2188860-1-naveen@kernel.org # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 4b3338aaa74d7d4ec5b6734dc298f0db94ec83d2 # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig Using /kisskb/src/arch/powerpc/configs/ppc64_defconfig as base Merging /kisskb/src/arch/powerpc/configs/le.config Merging /kisskb/src/arch/powerpc/configs/guest.config Value of CONFIG_VIRTIO_BLK is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_BLK=m New value: CONFIG_VIRTIO_BLK=y Value of CONFIG_SCSI_VIRTIO is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_SCSI_VIRTIO=m New value: CONFIG_SCSI_VIRTIO=y Value of CONFIG_VIRTIO_NET is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_NET=m New value: CONFIG_VIRTIO_NET=y Value of CONFIG_VIRTIO_CONSOLE is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_CONSOLE=m New value: CONFIG_VIRTIO_CONSOLE=y Value of CONFIG_VIRTIO_PCI is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_PCI=m New value: CONFIG_VIRTIO_PCI=y Value of CONFIG_VIRTIO_BALLOON is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_BALLOON=m New value: CONFIG_VIRTIO_BALLOON=y Value of CONFIG_VHOST_NET is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VHOST_NET=m New value: CONFIG_VHOST_NET=y Value of CONFIG_IBMVETH is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_IBMVETH=m New value: CONFIG_IBMVETH=y Value of CONFIG_IBMVNIC is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_IBMVNIC=m New value: CONFIG_IBMVNIC=y Merging /kisskb/src/arch/powerpc/configs/kvm_guest.config # # merged configuration written to .config (needs make) # # Added to kconfig CONFIG_PPC_SPLPAR=n # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_pseries_defconfig+NO_SPLPAR_powerpc-gcc13 # Build took: 0:03:25.746570
