  "message": "kprobes: Introduce kprobes jump optimization\n\nIntroduce kprobes jump optimization arch-independent parts.\nKprobes uses breakpoint instruction for interrupting execution\nflow, on some architectures, it can be replaced by a jump\ninstruction and interruption emulation code. This gains kprobs\u0027\nperformance drastically.\n\nTo enable this feature, set CONFIG_OPTPROBES\u003dy (default y if the\narch supports OPTPROBE).\n\nChanges in v9:\n - Fix a bug to optimize probe when enabling.\n - Check nearby probes can be optimize/unoptimize when disarming/arming\n   kprobes, instead of registering/unregistering. This will help\n   kprobe-tracer because most of probes on it are usually disabled.\n\nChanges in v6:\n - Cleanup coding style for readability.\n - Add comments around get/put_online_cpus().\n\nChanges in v5:\n - Use get_online_cpus()/put_online_cpus() for avoiding text_mutex\n   deadlock.\n\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: systemtap \u003csystemtap@sources.redhat.com\u003e\nCc: DLE \u003cdle-develop@lists.sourceforge.net\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nCc: Srikar Dronamraju \u003csrikar@linux.vnet.ibm.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Anders Kaseorg \u003candersk@ksplice.com\u003e\nCc: Tim Abbott \u003ctabbott@ksplice.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Jason Baron \u003cjbaron@redhat.com\u003e\nCc: Mathieu Desnoyers \u003ccompudj@krystal.dyndns.org\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nLKML-Reference: \u003c20100225133407.6725.81992.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
