[PATCH V3 0/5] Updates to EDAC and AMD MCE driver

From: Aravind Gopalakrishnan
Date: Thu Mar 03 2016 - 10:55:11 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
processors.

Patches 1, 2 and 3 are for upcoming processor.

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

Note 1: Introduced new patch for moving MCx_CONFIG MSR to mce.h
Note 2: The enums, amd_hwids[], and string arrays amd_core_mcablock_names[],
amd_df_mcablock_names[] are placed in arch/x86 as there are
follow-up patches which use them here.

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

Changes from V2: (per Boris suggestions)
- Incorporated all changes as suggested by Boris from here-
