Masami Hiramatsu c4ab0a8370 kprobes: tracing/kprobes: Fix to kill kprobes on initmem after boot ... commit 82d083ab60 upstream. Since kprobe_event= cmdline option allows user to put kprobes on the functions in initmem, kprobe has to make such probes gone after boot. Currently the probes on the init functions in modules will be handled by module callback, but the kernel init text isn't handled. Without this, kprobes may access non-exist text area to disable or remove it.
