aarch64 missing from Revert "perf/x86: Always store regs->ip in perf_callchain_kernel()"

[Eugene Loh]

Thanks for reverting that patch:

    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?
