Subject: [PATCH v3 0/3] perf: strcmp_cpuid_str() expression fixups

Set of fixes related to the comments here [1]. Mainly cleanups,
additional tests and refactoring since adding the new strcmp_cpuid_str()
metric expression.

I added the string replace function to the perf utils
rather than tools/lib/string.c because it didn't seem
easy to add tests for tools/lib.

Changes since v2:
  * Drop patches that were already applied (which makes the cover letter
    mostly redundant)
  * Avoid generating the compiler warning reported here [2]

Changes since v1:
  * s -> haystack
  * find -> needle

James Clark (3):
  perf pmu: Move pmu__find_core_pmu() to pmus.c
  perf pmus: Simplify perf_pmus__find_core_pmu()
  perf pmu: Remove unused function
