I have posted the currently merged V6-dev.x patches, along with notation for backport or not. Large chunks are still not identified either way. Please have a look at:

Feel free to request permission to comment (I think you can do that through Google Documents).
There are a bunch of candidates not yet merged, so once I merge V6-dev.7, I will update this document with additional patches.
Thanks
