The kernel might be easily uploaded to, you already have an old version at github...
As for the KK, I guess it is based on the MediaTek SDK for KK released here http : // labs. mediatek. com /site/global/developer_tools/mediatek_android/mediatek_sdk_android/index. gsp, so you can just create a diff between your codebase and the original SDK (which will be in a reasonable size) and upload to some file hosting service (or even github as a gist)
Thanks
