/*
   * include/linux/node.h - generic node definition
   *
   * This is mainly for topological representation. We define the 
   * basic 'struct node' here, which can be embedded in per-arch 
   * 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
