Two totally different things, unless you believe system memory always starts at physical address zero, which is very far from the case on the majority of ARM platforms. So replacing LPAE with "highmem" is pure misrepresentation and is inaccurate. PAE might be a better term, and is also the x86 term for this. -- 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/
