Well, I don't really have a great solution for that, other than hoping that 1/5 makes it into Linus' master at some point. I see that it's a stretch, but pulling 1/5 into 5.11 now would prepare the stage for the others to go via any tree, into 5.12-rc1? Or you could maybe take both 1/5 and 5/5 into your kvm-arm tree, and would hope that a git rebase later would sort this out for you? But I think you are much more experienced in those kind of issues, so happy to hear about any other solutions. Thanks, Andre
