Subject: [PATCH 0/2] perf: Fix POWER9 cpi_breakdown metricgroup

From: "Paul A. Clarke" <pc@...ibm.com>

The recent patches posted by Ian Rogers motivated a deeper dive into
the POWER9 perf metrics, which uncovered some additional issues:

- 'lsu_other_stall_cpi' doesn't work at all
- All of the "ICT" metrics are missing from the metricgroup

Paul A. Clarke (2):
  perf: Fix POWER9 metric 'lsu_other_stall_cpi'
  perf: Add missing metrics to POWER9 'cpi_breakdown'
