We don't even have HAVE_SMP defined for arm64 (just SMP, which is on in defconfig). In theory we don't need any specific SMP support for a new SoC as long as it uses a standard booting protocol (e.g. PSCI). But for whatever reason, I only received about four patches in this series, so can't see the rest. -- Catalin -- To unsubscribe from this list: send the line unsubscribe linux-samsung-soc in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
