It's a bit late, as we rely on them for other changes. Perhaps just fixes for the files that you are seeing build crashes on? I know a bunch of them went into Linus's tree for this issue, but we didn't backport them as I didn't know what was, and was not, needed. If you can pinpoint the files that cause crashes, I can dig them up. thanks, greg k-h
