By default, when tasks are specified (i.e. -p, -t or -u options) per-thread mmaps are created. Add an option to override that and force per-cpu mmaps. Further comments by peterz: So this option allows -t/-p/-u to create one buffer per cpu and attach all the various thread/process/user tasks' their counters to that one buffer? As opposed to the current state where each such counter would have its own buffer.
