I think you have taken previous ARM net JIT patches, so I think it
makes sense if you continue to do so.  I'm not knowledgable of the
JIT interface myself, all I can say about many of these patches is
that they look okay to me on a superficial basis.

I suspect you're doing more or less the same, but from a slightly
different perspective (presumably through not knowing ARM assembly.)
