[PATCH v1 0/7] Refactor cpuid and metric table lookup code

[Ian Rogers <irogers@google.com>]

Xu Yang <xu.yang_2@nxp.com> reported issues with the system metric
lookup:
https://lore.kernel.org/linux-perf-users/20241106085441.3945502-1-xu.yang_2@nxp.com/
These patches remove a lot of the logic relating CPUIDs to PMUs so
that the PMU isn't part of the question when finding a metric table.
For time reasons, it doesn't go as far as allowing system metrics
without a metric table as a metric table is needed for metrics to
refer to other metrics, and the refactoring of that resolution is a
hassle.

Ian Rogers (7):
  perf header: Move is_cpu_online to numa bench
  perf header: Refactor get_cpuid to take a CPU for ARM
  perf arm64 header: Use cpu argument in get_cpuid
  perf header: Avoid transitive PMU includes
  perf header: Pass a perf_cpu rather than a PMU to get_cpuid_str
  perf jevents: Add map_for_cpu
  perf pmu: Move pmu_metrics_table__find and remove ARM override
