[PATCH 0/9] perf: Adding better precise_ip field handling

[Jiri Olsa]

hi,
adding sysfs attribute to specify the maximum allowed value
for perf_event_attr::precise_ip field.

Adding functionality for simple 'precise' term to get the
maximum allowed value for perf_event_attr::precise_ip field.

And finally adding several precise automated tests.

thanks,
jirka
