They are pretty close to what they used be last time I posted them, save for the interface changes. I can send them to you if you want. For the toolstack it's a bit more complicated: I have patches that will apply to (I think) 3.16 or 3.17 but not to the latest tree --- there is huge amount of churn there and I gave up for now trying to chase them. OTOH, since the interfaces are (or appear to be) stable the binary from early tree works fine on the mainline. -boris
