Subject: [PATCH EDAC 0/6] Improvements for ghes_edac

This patch series complements the previous one sent:
	http://comments.gmane.org/gmane.linux.kernel/1442178

It contains:

- a patch removing the GHES_PFX macro, as requested by Joe Perches;
- a patch adding copyright notes and an entry at MAINTAINERS
  for the new driver;
- a patch suggested by Borislav moving the error description to an
  structure;
- 3 patches improving the error report for GHES-driven errors.

Patches were tested using a 4 cores machine.

With the patches, a GHES error like this one:

{1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 0
{1}[Hardware Error]: APEI generic hardware error status
{1}[Hardware Error]: severity: 2, corrected
{1}[Hardware Error]: section: 0, severity: 2, corrected
{1}[Hardware Error]: flags: 0x01
{1}[Hardware Error]: primary
{1}[Hardware Error]: section_type: memory error
{1}[Hardware Error]: error_status: 0x0000000000000400
{1}[Hardware Error]: node: 3
{1}[Hardware Error]: card: 0
{1}[Hardware Error]: module: 1
{1}[Hardware Error]: device: 0
{1}[Hardware Error]: error_type: 18, unknown

Was properly mapped to EDAC printk engine as:

EDAC MC0: 1 CE reserved error (18) on unknown label (node:3 card:0 module:1 page:0x0 offset:0x0 grain:0 syndrome:0x0 - status(0x0000000000000400): Storage error in memory (DRAM))

And to the corresponding RAS trace event:

mc_event: 1 Corrected error: reserved error (18) on unknown label (mc:0 location:-1:-1:-1 address:0x00000000 grain:1 syndrome:0x00000000 APEI location: node:3 card:0 module:1 status(0x0000000000000400): Storage error in memory (DRAM))

Mauro Carvalho Chehab (6):
  ghes_edac: remove GHES_PFX macro
  ghes_edac: add a MAINTAINERS entry and copyrights
  edac: put all arguments for the raw error handling call into a struct
  ghes_edac: Make it compliant with UEFI spec 2.3.1
  edac: add support on ras_event for error type "Info"
  ghes_edac: Fix RAS tracing
