Yes; as the references to CONFIG_* symbols in UAPI were a bug, I've already merged this patch for 3.10 as 8f657933a3c2086d4731350c98f91a990783c0d3 [MIPS: Quit exposing Kconfig symbols in uapi headers.] Ralf -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
