So, I stand corrected. It seems that at least one legacy system I'm looking at always specifies unit address as well. I don't like it but I'll stop arguing. Ben: The interesting part is that it does _not_ specify it on /memory though. Nor, of course, on /cpus or /openprom. So assuming /memory@0 exists will break even on some powerpc platforms. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
