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

From: Aravind Gopalakrishnan
Date: Mon Feb 29 2016 - 17:17:32 EST

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

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
