[PATCH 5/8] perf x86: Adding hardware events translations for p6 cpus

[Jiri Olsa]

Adding support for p6 processors to display 'events' sysfs
directory (/sys/devices/cpu/events/) with hw event translations.

  # ls  /sys/devices/cpu/events/
  branch-instructions
  branch-misses
  bus-cycles
  cache-misses
  cache-references
  cpu-cycles
  instructions
  ref-cycles
  stalled-cycles-backend
  stalled-cycles-frontend
