https://lore.kernel.org/r/20251104215405.168643-2-jolsa@kernel.org https://github.com/torvalds/linux/commit/6d08340d1e354787d6c65a8c3cdd4d41ffb8a5ed     Revert "perf/x86: Always store regs->ip in perf_callchain_kernel()"     This reverts commit 83f44ae. But it seems to me that this issue is not specific to x86.  For example, here is aarch64, using a 6.18 kernel:     # bpftrace -e 'tracepoint:sched:sched_process_exec { print(kstack()); }'         perf_trace_sched_process_exec+16         perf_trace_sched_process_exec+16         __traceiter_sched_process_exec+80         exec_binprm+908         bprm_execve.part.0+464         bprm_execve+68         do_execveat_common.isra.0+456         __arm64_sys_execve+76         invoke_syscall+112         el0_svc_common.constprop.0+264         do_el0_svc+36         el0_svc+56         el0t_64_sync_handler+184         el0t_64_sync+412 The leaf IP is repeated.  Are corresponding changes needed for processors other than just x86?
