Subject: [PATCH V2 0/5] Updates to EDAC and AMD MCE driver

This patchset mainly provides necessary EDAC bits to decode errors
occuring on Scalable MCA enabled processors and also updates AMD MCE
driver to program the correct MCx_MISC register address for upcoming
processors.

Patches 1, 2 and 3 are meant for the upcoming processors.

Patches 4 and 5 are either fixing or adding comments to help in
understanding the code and do not introduce any functional changes.

Patch 1: Move MSR definition to mce.h
Patch 2: Updates to EDAC driver to decode the new error signatures
Patch 3: Fix logic to obtain correct block address
Patch 4: Fix deferred error comment
Patch 5: Add comments to amd_nb.h to describe threshold_block structure

Tested V2 patches for regressions on Fam15h, Fam10h systems
and found none.

Note 1: Introduced new patch for moving MCx_CONFIG MSR to mce.h
Note 2: The enums ans amd_hwid_mappings[] array are placed in arch/x86
	as there are follow-up patches which need the struct there

Changes from V1: (per Boris suggestions)
  - Simplify error decoding routines
  - Move headers to mce.h
  - Rename enumerations and struct members (to be more descriptive)
  - Drop gerund usage
  - Remove comments that are spelling out the code

Aravind Gopalakrishnan (5):
  x86/mce: Move MCx_CONFIG MSR definition
  EDAC, MCE, AMD: Enable error decoding of Scalable MCA errors
  x86/mce/AMD: Fix logic to obtain block address
  x86/mce: Clarify comments regarding deferred error
  x86/mce/AMD: Add comments for easier understanding
