That is in fact where it comes from for those machines .. and in fact, I started removing it from various trees about a year ago. Up until recently, it was around for compatibility reasons .. but now the generic scsi subsystem provides everything that CONFIG_IDE used to .. and they can in fact be dropped. I may do it to the 4.1 kernel, or wait until after the upcoming release to avoid any chance of breaking something that still depends on it.
