oprofile_map_event: Decrease the sample period for the PPC64 events
The PPC970MP supports a minimum sample period of 10000 but the tool is automatically mappings for a period of 50000. The value was chosen to reduce the overhead of oprofile but the --sample-cycle-factor switch is there to achieve the same thing. Make the default sample period as low as is supported.
