[PATCH v2 0/6] lib/pmu: cleanups and trace integration

[Tomasz Duszynski]

This series does some cleanup and refactoring around the rc1 code like: trimming unused headers,
switching to callbacks for per-arch handling, and adding trace support. It also re-enables existing
base test to help catch reported issues on some architectures.

v2:
- explicitly check against NULL
- make pmu lib optional by checking if dpdk config has RTE_LIB_PMU

Tomasz Duszynski (6):
  lib/pmu: quiesce rte_pmu_read deprecation warning in chkincs
  lib/pmu: export only necessary arch headers
  lib/pmu: reimplement per-arch ops as callbacks
  lib/pmu: use build system defined RTE_LIB_PMU macro
  test/pmu: enable fast test
  trace: add PMU
