The first patch fixes a messed output of continuous lines when printing backtraces for all CPUs via NMI. It works well for me.
The other patches fix problems that I noticed when working on the first patch. It would be great if the respective maintainers could do some more testing of them. Well, it touches several modules. But they are related to one commit so I send them together. Note that the 4th patch depends on the 2nd one.
