+From b901fb0088a7605eec00af7b644e25987995d693 Mon Sep 17 00:00:00 2001
+From: Harish Sadineni <Harish.Sadineni@windriver.com>

+Subject: [PATCH] Add ARM64 syscall prefix detection in C++ API
+
+Fixes issue where bpf.get_syscall_fnname() on ARM64 returns bare
+syscall name instead of the prefixed __arm64_sys_ variant, causing
+kprobe attachment failures. Now detects ARM64 prefix alongside x64
+(__x64_sys_) and generic (sys_) prefixes.
+
+Fixes: #5350
+
+Upstream-Status: Submitted [https://github.com/iovisor/bcc/pull/5489]
