I've tested the patch:
1. arch/mips/net/bpf_jit.c is missing in master branch of linux-mips,
so it was ignored.
2. Other things are fine.

Should we add ".set arch=mips64r2" for using of wsbh/dsbh?
I can compile 3.15-rc8 with the patch applied, but when I tried the
patch on 3.10, it reported "unrecognized op dsbh..."

Should above line be replaced with the following line?
"#if cpu_has_wsbh"
