LMG Upstreaming

To ensure 'Upstreaming' as the foremost focus, we would strive to reduce and eventually eliminate the differences between the upstream kernel and these stable kernels.

The team would work closely with upstream kernel developers and developers of these mobile ecosystems to find ways to implement key features required in ways that meet the needs of all involved communities.

In addition to that the team provides "Androidization tree" for LSK and linux-linaro. The linaro-android tree is a forward port of the out-of-tree AOSP patches, where compatibility with the current released AOSP userland is prioritized. It provides a preview of what google's next AOSP common.git tree *might* look like.
