This is going to hit some of the patches that David has sent to tglx, I think. You might want to try to rebase on top of them (tip/time/for-xen, or something like that ) when they are ready. But for the Xen generic maintainer I am OK with these changes so you can stick Acked-by on them. Are you thinking to push them yourself or via the arm64 maintainer? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
