Dave Jiang 91b99041c1 drivers/edac: updated PCI monitoring
Moving PCI to a per-instance device model

This should include the correct sysfs setup as well. Please review.

Jason Uhlenkott 535c6a5303 drivers/edac: new inte 30x0 MC driver
Here's a driver for the Intel 3000 and 3010 memory controllers,
relative to today's Sourceforge code drop.  This has only had light
testing (I've yet to actually see it handle a memory error) but it
detects my hardware correctly.

Dave Jiang c0d1217202 drivers/edac: add new nmi rescan
Provides a way for NMI reported errors on x86 to notify the EDAC
subsystem pending ECC errors by writing to a software state variable.

Here's the reworked patch. I added an EDAC stub to the kernel so we can
have variables that are in the kernel even if EDAC is a module. I also
implemented the idea of using the chip driver to select error detection
mode via module parameter and eliminate the kernel compile option.
Please review/test. Thx!

Also, I only made changes to some of the chipset drivers since I am
unfamiliar with the other ones. We can add similar changes as we go.

Eric Wollesen eb60705ac5 drivers/edac: new intel 5000 MC driver
Eric Wollesen ported the Bluesmoke Memory Controller driver (written by Doug
Thompson) for the Intel 5000X/V/P (Blackford/Greencreek) chipset to the in
kernel EDAC model.

This patch incorporates the module for the 5000X/V/P chipset family

Douglas Thompson e27e3dac65 drivers/edac: add edac_device class
This patch adds the new 'class' of object to be managed, named: 'edac_device'.

As a peer of the 'edac_mc' class of object, it provides a non-memory centric
view of an ERROR DETECTING device in hardware. It provides a sysfs interface
and an abstraction for varioius EDAC type devices.

Multiple 'instances' within the class are possible, with each 'instance'
able to have multiple 'blocks', and each 'block' having 'attributes'.

At the 'block' level there are the 'ce_count' and 'ue_count' fields
which the device driver can update and/or call edac_device_handle_XX()
functions. At each higher level are additional 'total' count fields,
which are a summation of counts below that level.

This 'edac_device' has been used to capture and present ECC errors
which are found in a a L1 and L2 system on a per CORE/CPU basis.

Douglas Thompson 7c9281d76c drivers/edac: split out functions to unique files
This is a large patch to refactor the original EDAC module in the kernel
and to break it up into better file granularity, such that each source
file contains a given subsystem of the EDAC CORE.

Originally, the EDAC 'core' was contained in one source file: edac_mc.c
with it corresponding edac_mc.h file.

Now, there are the following files:

edac_module.c	The main module init/exit function and other overhead
edac_mc.c	Code handling the edac_mc class of object
edac_mc_sysfs.c	Code handling for sysfs presentation
edac_pci_sysfs.c  Code handling for PCI sysfs presentation
edac_core.h	CORE .h include file for 'edac_mc' and 'edac_device' drivers
edac_module.h	Internal CORE .h include file

This forms a foundation upon which a later patch can create the 'edac_device'
class of object code in a new file 'edac_device.c'.

Alan Cox da9bb1d27b [PATCH] EDAC: core EDAC support code
This is a subset of the bluesmoke project core code, stripped of the NMI work
which isn't ready to merge and some of the "interesting" proc functionality
that needs reworking or just has no place in kernel.  It requires no core
kernel changes except the added scrub functions already posted.

The goal is to merge further functionality only after the core code is
accepted and proven in the base kernel, and only at the point the upstream
extras are really ready to merge.

From: doug thompson <norsk5@xmission.com>

  This converts EDAC to sysfs and is the final chunk neccessary before EDAC
  has a stable user space API and can be considered for submission into the
  base kernel.
