 * include/linux/node.h - generic node definition

 * This is mainly for topological representation. We define the

 * definitions of processors.
 *
 * Basic handling of the devices is done in drivers/base/node.c
 * and system devices are handled in drivers/base/sys.c. 
 *
 * Nodes are exported via driverfs in the class/node/devices/
 * directory. 
 *
 * Per-node 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
