 * include/linux/node.h - generic node definition
3
 *
4
 * This is mainly for topological representation. We define the
5
 * basic 'struct node' here, which can be embedded in per-arch
6
 * definitions of processors.
7
 *
8
 * Basic handling of the devices is done in drivers/base/node.c
9
 * and system devices are handled in drivers/base/sys.c.
10
 *
11
 * Nodes are exported via driverfs in the class/node/devices/
12
 * directory.
13
 *
14
 * Per-node interfaces can be implemented using a struct device_interface.
15
 * See the following for how to do this:
16
 * - drivers/base/intf.c
17
 * - Documentation/driver-model/interface.txt
