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-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-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_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig Using /kisskb/src/arch/powerpc/configs/mpc85xx_base.config as base Merging /kisskb/src/arch/powerpc/configs/85xx-32bit.config Merging /kisskb/src/arch/powerpc/configs/85xx-hw.config Merging /kisskb/src/arch/powerpc/configs/fsl-emb-nonhw.config # # merged configuration written to .config (needs make) # # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4579:warning: override: reassigning to symbol PPC_E500MC .config:4580:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/build_bug.h:5, from /kisskb/src/include/linux/container_of.h:5, from /kisskb/src/include/linux/list.h:5, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:15: /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c: In function 'allocate_bd': /kisskb/src/include/linux/err.h:28:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 28 | #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) | ^ /kisskb/src/include/linux/compiler.h:77:45: note: in definition of macro 'unlikely' 77 | # define unlikely(x) __builtin_expect(!!(x), 0) | ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:138:13: note: in expansion of macro 'IS_ERR_VALUE' 138 | if (IS_ERR_VALUE(fep->ring_mem_addr)) | ^~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 # Build took: 0:03:40.841578
