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-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 4b3338aaa74d7d4ec5b6734dc298f0db94ec83d2 # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc83xx_defconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 # Build took: 0:01:40.204646
