Ingo Molnar 0ec04e16d0 perf sched: Add 'perf sched map' scheduling event map printout 
This prints a textual context-switching outline of workload
captured via perf sched record.

For example, on a 16 CPU box it outputs:

Columns stand for individual CPUs, from CPU0 to CPU15, and the
two-letter shortcuts stand for tasks that are running on a CPU.

'*' denotes the CPU that had the event.

A dot signals an idle CPU.

New tasks are assigned new two-letter shortcuts - when they occur
first they are printed. In the above example 'T1' stood for irqbalance:

      T1 => irqbalance:2089
