Subject: [PATCH 184/201] perf test: Verify more event members in pmu-events
 test

mainline inclusion
from mainline-v5.16-rc1
commit 56be05103a408b7f56c5e75717b2b23a5adf1ddb
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8C0CX

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=56be05103a408b7f56c5e75717b2b23a5adf1ddb

----------------------------------------------------------------------

Function compare_pmu_events() does not compare all struct pmu-events
members, so add tests for missing members "name", "event", "aggr_mod",
"event", "metric_constraint", and "metric_group", and re-order the tests
to match current struct pmu-events member ordering.

Also fix uncore_hisi_l3c_rd_hit_cpipe.event member, now that we're
actually testing it.
