Easiest way to get Permissive SELinux? topic

I will have a Note 4 in a few days.

I'm thinking about getting an AppRadio, and in order to use ARUnchained or the like on it, it looks like I might need to have SELinux be off or set to permissive, or something of that nature.

I know it's possible to do this with various kernels on the development forum, but I'm wondering what the easiest way to do this is, if I want it to be stock or as close to stock as is possible, just with permissive SELinux.

I've tried to figure this out on my own, but the closest I can find is flashing a kernel with a whole lot of other modifications, which I don't necessarily want to do at first. Anyone know of any other way, or of a kernel where there are not so many modifications?

Thanks for any help!
