forked from mirrors/linux
		
	register_node() is defined as extern in include/linux/node.h. But the function is only called from register_one_node() in driver/base/node.c. So the patch defines register_node() as static.

/*

 * 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.
