Instead of playing with Kconfig selections let's check if we set up dummy (null) legacy PIC during startup and abort i8042 initialization as well. This should fix the following bug: ---- The presence of 8042 and 8259 are orthogonal. In fact, there are quite a few systems on the market which have 8259 but not 8042, and at least having the ability to handle that correctly instead of just assuming that those I/O ports are safe is pretty key. So please don't commingle these completely unrelated platform attributes. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.
