Yinghai,

Theoretically removing clearing with nodes_parsed can work fine except that it requires more 
consideration, since some functions already based on nodes_parsed, like acpi_get_nodes(), is 
supposing nodes_parsed just represents for nodes with memory on.

See my another email to David, I think we'd better keep hotpluggable node info separately since it 
is straightforward as well as would be useful for future hotplug related usage. How do you think 
about it? thanks.
