Hi Ludo',

here's updated patch set.

Indeede it's adding another linux-libre kernel since this opens the attack surface for anybody not using the binder and ashmem interface. However, it bring the support for Android apps on Linux which might be necessary on mobile platforms such as PinePhone. 

Any thoughts about upstreaming this?

FIY There are also open source implementation of Andorid apps that can be downloaded from F-Droid [1]
