Just to be clear in case it doesn't look aligned with Arnd's comment. I'm referring to the 32-bit ARM port - it has the same important place as before, nothing from the 32-bit architecture code is thrown away (over time, we may want to clean up old architecture versions but that's a normal thing). How the 32-bit ARM SoC is refactored and maintained it's up to the arm-soc team and they are doing a great job. -- Catalin -- 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/
