fix more broken shit from 3b729ec3fd0460f248acf4e7b8f0f33eb9db69cb

please do not cherry-pick any feature related commits from other ROMs unless you are
doing a complete port of the feature.  All this is going to do is break the build and
introduce a shit ton of dead/broken code and unnecessary "reconciliations" with code we
DO NOT WANT.
