The sysbus change is already in master, but I didn't want to rebase the tree. I verified there's no conflict when merging.
The only thing that might be controversial here is the bridge migration path, but the patch was out for pretty long without comments (besides a style comment by Stefan Weil, fixed that), and it's not changing anything that isn't already broken. Maybe it's fine, or maybe merging it will make people notice ;).
