AMD-based systems currently use a "NodeId" when referencing a
software-visible hardware structure. This may be referred to as a "Die"
in x86 documentation, "Node" in some AMD documentation, and "Package" in
Linux documentation.

Recently a cpu_die_id value was added to struct cpuinfo_x86. This value
can be used on AMD-based systems rather than using an AMD-specific value
throughout the kernel.

This set is based on patches 1-3 from the following set.

Thanks,
Yazen

Yazen Ghannam (4):
  x86/CPU/AMD: Save AMD NodeId as cpu_die_id
  x86/CPU/AMD: Remove amd_get_nb_id()
  EDAC/mce_amd: Use struct cpuinfo_x86.cpu_die_id for AMD NodeId
  x86/topology: Set cpu_die_id only if DIE_TYPE found
