The GENERIC kernel contains support for all sorts of devices that you probably don't have on your machine. The code to support these devices is all part of the kernel text that is loaded and pinned into kernel memory. All this code for devices you don't have wastes RAM, which you could put to use for user programs, file cache, etc. -Dave
