I wouldn't expect most population to build their own kernels on tablets/phones. And even if you could install a custom kernel, mainline rarely runs on such devices because of tons of out of tree patches (just look at the Nexus 9 patches that Kumar pointed at; even ignoring the booting protocol they are extremely far from an upstreamable form). -- Catalin -- 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/
