Example #3

File: hotplug.c Project: fahrukhan/KK_Kernel_fortunave3g

static inline void platform_do_lowpower(unsigned int cpu, int *spurious)

			 */

		 * getting here, means that we have come out of WFI without
		 * having been woken up - this shouldn't happen
		 *
		 * The trouble is, letting people know about this is not really
		 * possible, since we are currently running incoherently, and
		 * therefore cannot safely call printk() or anything else
