From: Steven Rostedt The wake up code that triggers klogd does not really matter which CPU it enables the wake up on. Every CPU will be doing a printk_tick() and check the current CPU. As long as one of the CPUs triggers the wakeup we are fine. Use __this_cpu_write() instead of this_cpu_write() to show that we do not care.
