This reverts commit 3adee7a7976012a20f1d3b5a529a3c105e29fef1. After upgrading to v3.15, my laptop's battery started draining quite fast. Powertop pointed to the deep RC6 states not being used. The kernel param I had put to enable them had stopped working the way it used to; so I disagree with the 'not maintaing ABI' part of the param name change. However weird the names may be, they're in active use and changing them only causes pain for users. This also isn't advertised (marked deprecated, big warning shown, etc.), so just reverting now.
