Ok, that sounds like a good idea. I'm uncertain how best to coordinate with Dave Young's patch series to avoid conflicts. His first patch does the signature change (and adds the early_memunmap function but that isn't used anywhere): https://lkml.org/lkml/2013/12/20/143 Any thoughts on how best to avoid potential merge conflicts here?
