Applied to arm64 (for-next/bpf), thanks!
[1/3] arm64: insn: Fix two bugs in encoding 32-bit logical immediates https://git.kernel.org/arm64/c/579d1b3faa37 [2/3] bpf, arm64: Optimize AND,OR,XOR,JSET BPF_K using arm64 logical immediates https://git.kernel.org/arm64/c/fd49591cb49b [3/3] bpf, arm64: Optimize ADD,SUB,JMP BPF_K using arm64 add/sub immediates https://git.kernel.org/arm64/c/fd868f148189
