These all benchmarks are for ARMv7.
Thanks! In the future, try to avoid the white-space damage
(line-wrapping). And it looks like you've still got debugging turned
on in your jit code:

[   56.176033] test_bpf: #21 LD_CPU
[   56.176329] bpf_jit: *** NOT YET: opcode 85 ***
[   56.176565] jited:0 2639 702 PASS

That breaks the test report line. After I cleaned these up and parsed
the results, they look great. Most things are half the speed of the
interpreter, if not better. Only the LD_ABS suffered, and that's
mainly the const blinding, I assume.

Please post your current patch. Thanks for this!
