I only squashed patches 1+2 to have the functionality in one place. And fixed a typo in patch 1. Thanks to the testers and reviewers, and especially Hans, for the input and discussions. This will now get a full test cycle in -next. Let's see what happens... And let's move on to how to add 'very late transfers without irqs' on top of this series. Happy hacking, Wolfram
