x86: fix early cpu_to_node panic from nr_free_zone_pages
call early_cpu_to_node() since per_cpu(cpu_to_node_map) might not be setup yet. 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 <travis@sgi.com> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
