v3: https://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg116800.html
For v4, patch 5/6 is new and has been moved into this series. It has also been updated to use strlcat() instead of strncat(). No other changes. Also, though patch 3/6 is generic, it needs to be carried in this series as we crash on powerpc without that patch. - Naveen Masami Hiramatsu (1): kprobes: Skip preparing optprobe if the probe is ftrace-based Naveen N. Rao (5): powerpc: ftrace: minor cleanup powerpc: ftrace: restore LR from pt_regs powerpc: kprobes: add support for KPROBES_ON_FTRACE powerpc: introduce a new helper to obtain function entry points powerpc: kprobes: prefer ftrace when probing function entry .../debug/kprobes-on-ftrace/arch-support.txt | 2 +- arch/powerpc/Kconfig | 1 + arch/powerpc/include/asm/code-patching.h | 37 ++++++++ arch/powerpc/include/asm/kprobes.h | 10 ++ arch/powerpc/kernel/Makefile | 3 + arch/powerpc/kernel/entry_64.S | 19 ++-- arch/powerpc/kernel/kprobes-ftrace.c | 104 +++++++++++++++++++++ arch/powerpc/kernel/kprobes.c | 25 ++++- arch/powerpc/kernel/optprobes.c | 6 +- kernel/kprobes.c | 11 ++- 10 files changed, 199 insertions(+), 19 deletions(-) create mode 100644 arch/powerpc/kernel/kprobes-ftrace.c -- 2.12.1
