Description of problem:
Somewhere between RHEL-9.1 and RHEL-9.2 perf became unable to print function names in kernel stack traces from events on aarch64 unless kernel-debuginfo is installed. On RHEL-9.1 and also on all other arches on RHEL-9.2/9.3 it is able to infer the function names without it (presumably using /proc/kallsyms).

The issue also appears when I boot a RHEL-9.2 kernel on RHEL-9.1 userspace, so it seems to be a regression in the kernel rather than the userspace tools/libraries.

Version-Release number of selected component (if applicable):
Last known good: kernel-5.14.0-162.23.1.el9_1.aarch64
First known bad: kernel-5.14.0-284.14.1.el9_2.aarch64

How reproducible:
Always.

Steps to Reproduce:
1. perf record -g sleep 1
2. perf script

Actual results:
perf-exec 21437 257.001297: 1 cycles:
