Right, so after Matt and I talked about it a bit on IRC, we actually don't really care how we do the mappings if we spell them out later to kexec over proc or somewhere else, as you wanted. So we can do the VA address space saving scheme first and change it later, if there are issues. We'll see. Thanks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
