Meta-comment, do we really care about Alpha anymore? Is it still consered an "active" arch we support? I haven't seen a single alpha-related stable patch in _years_ if at all, which implies to me that no one is even using it. Not that stable patches for architectures are a valid reference for how much they are used, but it does give me a good indication of what arches have users that actually care about a modern (i.e. within the past 5 years) kernel. thanks, greg k-h -- 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/
