I've applied them, with (very) minor readability edits here and there, and will push them out into tip:x86/mm and tip:master after some testing - you can use that as a base for the remaining submissions. I've also applied the GUP patch, with the assumption that you'll address Linus's request to switch x86 over to the generic version. Thanks, Ingo
