+/*
+ * cpu.h - generic cpu defition
+ *
+ * This is mainly for topological representation. We define the 
+ * basic 'struct cpu' here, which can be embedded in per-arch 
+ * definitions of processors.
+ *
+ * Basic handling of the devices is done in drivers/base/cpu.c
+ * and system devices are handled in drivers/base/sys.c. 
+ *
+ * CPUs are exported via driverfs in the class/cpu/devices/
+ * directory. 
+ *
+ * Per-cpu interfaces can be implemented using a struct device_interface. 
+ * See the following for how to do this: 
+ * - drivers/base/intf.c 
+ * - Documentation/driver-model/interface.txt
+ *
