Subject: [PATCH net-next 0/8] Add complementary BPF conditional jump instructions

This set adds adds jump operations for lt (<), le (<=), ne (!=) that
compare A with K resp. X in order to facilitate filter programming
with conditional jumps, as also available in McCanne et. al's BPF+
paper (``BPF+: Exploiting Global Data-flow Optimization in a Generalized
Packet Filter Architecture'').

Also, follow-up BPF JIT implementations for x86, Sparc and PowerPC
are added in this set.

Daniel Borkmann (8):
  net: bpf: add lt,le jump operations to bpf machine
  x86: bpf_jit_comp: add JMP instructions for BPF JIT
  sparc: bpf_jit_comp: add JMP instructions for BPF JIT
  PPC: bpf_jit_comp: add JMP instructions for BPF JIT
  net: bpf: add neq jump operations to bpf machine
  x86: bpf_jit_comp: add JMP_NEQ instructions for BPF JIT
  sparc: bpf_jit_comp: add JMP_NEQ instructions for BPF JIT
  PPC: bpf_jit_comp: add JMP_NEQ instructions for BPF JIT
