Subject: [PATCH v4 0/4] x86/edac/amd64: Add support for noncpu nodes

On newer heterogeneous systems with AMD CPUs the data fabrics of GPUs
can be connected directly via custom links.

This patchset does the following
1. amd_nb.c:
   a. Add support for northbridges on Aldebaran GPU nodes
   b. export AMD node map details to be used by edac and mce modules
	
2. mce_amd module:
   a. Identify the node ID where the error occurred and map the node id
      to linux enumerated node id.

2. Modifies the amd64_edac module
   a. Add new family op routines
   b. Enumerate UMCs and HBMs on the GPU nodes

This patchset is rebased on top of
