ACPI: Only count valid srat memory structures
Otherwise you could run into: WARN_ON in numa_register_memblks(), because node_possible_map is zero References: https://bugzilla.novell.com/show_bug.cgi?id=757888 On this machine (ProLiant ML570 G3) the SRAT table contains: - No processor affinities - One memory affinity structure (which is set disabled) CC: Per Jessen <per@opensuse.org> CC: Andi Kleen <andi@firstfloor.org> Signed-off-by: Thomas Renninger <trenn@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
