Here are several improvements and bug fixes for the MIPS eBPF JIT.

The main change is the addition of support for JLT, JLE, JSLT and JSLE
ops, that were recently added.

Also fix WARN output when used with preemptable kernel, and a small
cleanup/optimization in the use of BPF_OP(insn->code).

I suggest that the whole thing go via the BPF/net-next path as there
are dependencies on code that is not yet merged to Linus' tree.

Yes, this would be via net-next.

Still pending are changes to reduce stack usage when the verifier can
determine the maximum stack size.

Awesome, thanks a lot!
