There is a little bit of dependency juggling across trees, but patches are pretty trivial. Ideally if Andrew accepts this patch and queues it up for next, then the arch patches would be merged through those trees then patch 3 gets sent by Andrew. I've tested this with other powerpc and vmalloc patches, with code that explicitly tests vmalloc_to_page on vmalloced memory and results look fine.
