We are preparing patches at the moment to allow the kernel to support a userspace compiled with the new ABI, however the kernel itself still needs to be built using the old ABI.

 

I'm not sure how hard it would be to compile a kernel with the new ABI. It mostly compiles now however I'm guessing there's probably some code that would need porting to make it functional.

The ABI is still under development so there isn't any documentation available for it yet.
