3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Seiji Aguchi <[email protected]> commit 62be73eafaa045d3233337303fb140f7f8a61135 upstream. This patch moves kmsg_dump(KMSG_DUMP_PANIC) below smp_send_stop(), to serialize the crash-logging process via smp_send_stop() and to thus retrieve a more stable crash image of all CPUs stopped.
