static int setup_nodes(struct perf_session *session)
The node header array contains 3 items, each item is used for one of the 3 flavors for node accessing info. To extend sorting on other snooping type and not always stick to HITMs, the second header string "Node{cpus %hitms %stores}" should be adjusted (e.g. it's changed as "Node{cpus %peer %stores}"). For this reason, this patch changes the node header array to three flat variables and uses switch-case in function setup_nodes_header(), thus it is easier for altering the header string.
