I also had to export x86_cpu_to_node_map_early_ptr because of some calls from the network code to numa_node_id(): net/ipv4/netfilter/arp_tables.c: net/ipv4/netfilter/ip_tables.c: net/ipv4/netfilter/ip_tables.c: Signed-off-by: Mike Travis Cc: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- diff --git a/arch/x86/mm/numa_64.c b/arch/x86/mm/numa_64.c index 70b463abf6..441af4edea 100644 --- a/arch/x86/mm/numa_64.c +++ b/arch/x86/mm/numa_64.c @@ -37,9 +37,7 @@ u16 x86_cpu_to_node_map_init[NR_CPUS] = { void *x86_cpu_to_node_map_early_ptr; DEFINE_PER_CPU(u16, x86_cpu_to_node_map) = NUMA_NO_NODE; EXPORT_PER_CPU_SYMBOL(x86_cpu_to_node_map); -#ifdef CONFIG_DEBUG_PER_CPU_MAPS EXPORT_SYMBOL(x86_cpu_to_node_map_early_ptr); -#endif u16 apicid_to_node[MAX_LOCAL_APIC] __cpuinitdata = { [0 ...
