You also need at least the first two:

   * 3d0220f6861d713213b015b582e9f21e5b28d2e0 ("bpf: Wrap aux data inside bpf_sanitize_info container")
   * bb01a1bba579b4b1c5566af24d95f1767859771e ("bpf: Fix mask direction swap upon off reg sign change")
   * a7036191277f9fa68d92f2071ddc38c09b1e5ee5 ("bpf: No need to simulate speculative domain for immediates")

They already went to 5.4/5.10/5.12 stable.

Thanks,
Daniel
