Subject: [PATCH v9 02/16] perf jevents: Add common software event json
Add json for software events so that in perf list the events can have
a description. Common json exists for the tool PMU but it has no
sysfs equivalent. Modify the map_for_pmu code to return the common map
(rather than an architecture specific one) when a PMU with a common
name is being looked for, this allows the events to be found.
