Andriod User Space boot-up on Vanilla Kernel

[JJ]

As after release of Vanilla Kernel 3.3 essential Android Features to boot an Android User Space have been merged in mainline Kernel.

So anybody has tried with this combination(compiled Vanilla Kernel with Android Features + Android User Space-File System compiled from AOSP).

Is it working fine? I mean Vanilla Kernel is able to boot Android?

Vanilla Kernel v3.12.45 I'm thinking to use.

I'm planning to port complete Android on ARM based board.

Guidance needed.
