A long list of arguments looks not good:
E.g: static int process_sample_event(struct perf_tool *tool,
union perf_event *event,
struct perf_sample *sample,
struct perf_evsel *evsel,
struct machine *machine)
That would make extension of the context easier as well in the
future.
Ingo Molnar suggested to refactor code by this way.

I don't like it, in most cases it just moves variables from the function
signature to the start of the function.
I do agree tho that we should reduce the number of parameters as much as
we can, as I did removing that pevent one that we used to look up
event_format from the sample ID, that just was not natural as we already
had the evsel and did the lookup when reading the perf.data headers, so
it was just a matter of linking evsel to event_format at that point and
remove the pevent parameter and eliminate the needless relookups, see:
"perf evsel: Cache associated event_format"
fcf65bf149afa91b875ffde4455967cb63ee0be9
In the above function signature there is already room for tool specific
state in perf_tool/container_of, the other parameters are per event
natural objects.
