The main changes are: 1) Mitigate a Spectre v4 leak in unprivileged BPF from speculative pointer-as-scalar type confusion, from Luis Gerhorst. 2) Fix a splat when pid 1 attaches a BPF program that attempts to send killing signal to itself, from Hao Sun. 3) Fix BPF program ID information in BPF_AUDIT_UNLOAD as well as PERF_BPF_EVENT_PROG_UNLOAD events, from Paul Moore. 4) Fix BPF verifier warning triggered from invalid kfunc call in backtrack_insn, also from Hao Sun. 5) Fix potential deadlock in htab_lock_bucket from same bucket index but different map_locked index, from Tonghao Zhang.
