函数名称：To workaround broken NUMA config. Read the comment in* srat_detect_node().

函数原型：static int nearby_node(int apicid)

返回类型：int

参数：

类型参数名称
intapicid
293  以i大于等于0循环
294  node等于__apicid_to_node[] stores the raw mapping between physical apicid and* node and is used to initialize cpu_to_node mapping[i]
295  如果node不等于NUMA_NO_NODE且NUMA节点状态(node)则返回:node
298  以i小于MAX_LOCAL_APIC循环
299  node等于__apicid_to_node[] stores the raw mapping between physical apicid and* node and is used to initialize cpu_to_node mapping[i]
300  如果node不等于NUMA_NO_NODE且NUMA节点状态(node)则返回:node
303  返回:FIXME: better would be to fix all architectures to never return> MAX_NUMNODES, then the silly min_ts could be dropped. (node_online_map)
