Current ARM64 BPF JIT doesn't have store immediate and XADD instructions support, and aarch64 doesn't have native instructions for them. Implement them in instruction sequence. For detail, please refer to the commit log.
The implementation is tested by test_bpf kernel module.
The patches are applied after my BPF JIT stack fix [1].
