Any reason that any of these > cannot or should not be back-ported to go into 4.0.1? > They should be safe to backport, the only ones we should be extra careful are the TSC related patches, and you were the one to raise that complain :) If you have some spare time to test 21445 and 21339 on 4.0.1 to make sure that everything keeps working as expected, then we can safely apply them to xen 4.0 testing. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
