Dave Jones mentioned that he feels silly enabling EMBEDDED on iSeries... I am thinking about changing it to "EMBEDDED || !X86_PC" to safe-guard the most common platform from accidenially disabling it. I am still not convinced whether INPUT=m makes sence, especially if we make ACPI use input layer... Jan's example about input device with hot-pluggable keyboard is a bit of a stretch. -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
