Note, patch 3 shouldn't compile due to a typo in a .size directive. It does for me, so I could test this! But, it didn't for Olof. Aside from that (which perhaps Olof would fixup during patch application?), Acked-by: Stephen Warren I also have a query on patch 3 about enabling coresight, but that's more for my education than something that'd block patch application. -- nvpublic -- 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/
