Josh Poimboeuf (3):
      objtool: Add frame-pointer-specific function ignore
      objtool: Ignore unwind hints for ignored functions
      x86/kprobes: Add UNWIND_HINT_FUNC on kretprobe_trampoline()

Masami Hiramatsu (19):
      kprobes: treewide: Cleanup the error messages for kprobes
      kprobes: Fix coding style issues
      kprobes: Use IS_ENABLED() instead of kprobes_built_in()
      kprobes: Add assertions for required lock
      kprobes: treewide: Use 'kprobe_opcode_t *' for the code address in get_optimized_kprobe()
      kprobes: Use bool type for functions which returns boolean value
      ia64: kprobes: Fix to pass correct trampoline address to the handler
      kprobes: treewide: Replace arch_deref_entry_point() with dereference_symbol_descriptor()
      kprobes: treewide: Remove trampoline_address from kretprobe_trampoline_handler()
      kprobes: treewide: Make it harder to refer kretprobe_trampoline directly
      kprobes: Add kretprobe_find_ret_addr() for searching return address
      ARC: Add instruction_pointer_set() API
      ia64: Add instruction_pointer_set() API
      arm: kprobes: Make space for instruction pointer on stack
      kprobes: Enable stacktrace from pt_regs in kretprobe handler
      x86/kprobes: Push a fake return address at kretprobe_trampoline
      x86/unwind: Recover kretprobe trampoline entry
      tracing: Show kretprobe unknown indicator only for kretprobe_trampoline
      x86/kprobes: Fixup return address in generic trampoline handler

Punit Agrawal (5):
      kprobes: Do not use local variable when creating debugfs file
      kprobes: Use helper to parse boolean input from userspace
      kprobe: Simplify prepare_kprobe() by dropping redundant version
      csky: ftrace: Drop duplicate implementation of arch_check_ftrace_location()
      kprobes: Make arch_check_ftrace_location static
