Subject: [PATCH v2 net-next 0/2] bpf/verifier: disassembly improvements

Fix the output of print_bpf_insn() for ALU ops that don't look like
 compound assignment (i.e. BPF_END and BPF_NEG).

Sample output for a short test program:
0: (b4) (u32) r0 = (u32) 0
1: (dc) r0 = be32 r0
2: (84) r0 = (u32) -r0
3: (95) exit
processed 4 insns, stack depth 0

Edward Cree (2):
  bpf/verifier: improve disassembly of BPF_END instructions
  bpf/verifier: improve disassembly of BPF_NEG instructions
