[PATCHv4 0/8] perf, tool: Allow to use hw events in PMU syntax

[Jiri Olsa <jolsa@redhat.com>]

hi,
here's the change to make following syntax available:
  perf stat -e cpu/event=instructions/u ls
  perf stat -e cpu/cycles/u ls

this is identical to:
  perf stat -e instructions:u ls
  perf stat -e cycles:u ls

v4 changes:
  - kernel change is now structured differently allowing
    to pick up cpu differences
  - added support for intel/p6/amd PMUs - intel and amd tested,
    did not get p6 server, but should be ok.. feel free to omit

Attached patches:
  1/8 perf x86: Making hardware events translations available in sysfs
  2/8 perf x86: Filter out undefined events from sysfs events attribute
  3/8 perf x86: Adding hardware events translations for intel cpus
  4/8 perf x86: Adding hardware events translations for amd cpus
  5/8 perf x86: Adding hardware events translations for p6 cpus
  6/8 perf tools: Fix pmu object alias initialization
  7/8 perf tools: Add support to specify hw event as pmu event term
  8/8 perf test: Add automated tests for pmu sysfs translated events
