perf tools: Add mem2node object Adding mem2node object to allow the easy lookup of the node for the physical address. It has following interface: int mem2node__init(struct mem2node *map, struct perf_env *env); void mem2node__exit(struct mem2node *map); int mem2node__node(struct mem2node *map, u64 addr); The mem2node__toolsinit initialize object from the perf data file MEM_TOPOLOGY feature data. Following calls to mem2node__node will return node number for given physical address. The mem2node__exit function frees the object.
