Subject: [PATCH v1 2/4] perf script: Add "struct machine" parameter to process_event callback
Include a "struct machine*" parameter to the process_event callback in
the scripting layer. This will allow access to the perf_env from within
this callback.
Followup patches will build on top of this to report the correct name of
the registers in a perf.data file, consistently with the architecture
the file was recorded in.
