[PATCH net-next] sparc: bpf_jit_comp: add XOR instruction for BPF JIT JIT

[Daniel Borkmann <dxchgb@gmail.com>]

This patch is a follow-up for patch "filter: add XOR instruction for use
with X/K" that implements BPF SPARC JIT parts for the BPF XOR operation.

 I don't own a SPARC machine. This code is untested and uncompiled, but
 following the other instructions, this should integrate cleanly. Can
 someone confirm that? Thanks.
