Acked-by: David Rientjes <rient...@google.com> cpu_to_node(cpu) should return the correct node that was parsed from the SRAT on x86 at boot during CPU_UP_PREPARE. If any platform returns NUMA_NO_NODE, the worst case scenario is that we get local allocation anyway. -- 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/
