Hi,
I've had a look at the 4.2 tree last night, and started rebasing our stuff.
A couple of notable changes, some of which may require some extra work:

- Some Ethernet support was added. In the rebased version, I've dropped the frameworks/base part of the ECM bits (because something similar is already there). We may have to modify the ECM settings bits to work with the new Ethernet stuff or bring back ECM if it turns out to be more powerful
- fake vsync is now supported out of the box, our patch for that is no longer needed. The property has a different name though - if anything uses sf.force_sw_vsync, it needs to be updated to use debug.sf.no_hw_vsync
- Bluez was dropped in favor of a new Bluetooth stack. I doubt this affects any of our builds a lot.
- the "prebuilts" tree now includes "platform/prebuilts/clang/linux-x86/3.2", looks like someone is considering to move away from gcc. It'll be interesting to benchmark this against Linaro gcc (if llvm 2.9 is any indication, its optimization will come nowhere near ours - but of course they haven't been sitting around idle)

I've pushed a linaro_android_4.2 tree, but it's not ready yet (in particular, only the galaxynexus manifest has been updated, trying to get one build up first).
