Subject: [PATCH 00/13] Convert EDAC internal strutures to support all types of Memory Controllers

This is the 12th and final rebase of this patch series.

It is the first patchset for the EDAC rewrite. On this patchset,
there are all the internal changes at the EDAC core, needed
to properly represent memories at modern memory controllers that
aren't oriented per rank/channel.

It is needed in order to fix a long-term bug at the EDAC drivers
for the Intel memory controllers deployed since 2005 (well, in fact,
there is one Rambus that it is older, but also suffers from the same
syndrome), including the drivers for the recent Intel Nehalem and
Sandy Bridge architectures.

The new EDAC architecture supports both per rank/channel memory
controllers and per-DIMM ones.

On this changeset, there are no changes at the sysfs nodes. Just 
like before this changeset, non-per-rank memory controllers 
will expose memories as "virtual csrows/virtual channels[1].

[1] It sounds better to say "virtual" than to admit that all
EDAC Intel drivers since 2005 need to lie about their age to
the EDAC core, in order for the Kernel to accept them ;)

Mauro Carvalho Chehab (13):
  edac: Create a dimm struct and move the labels into it
  edac: move dimm properties to struct memset_info
  edac: Don't initialize csrow's first_page & friends when not needed
  edac: move nr_pages to dimm struct
  edac: Fix core support for MC's that see DIMMS instead of ranks
  edac: Initialize the dimm label with the known information
  edac: Cleanup the logs for i7core and sb edac drivers
  i5400_edac: improve debug messages to better represent the filled
    memory
  events/hw_event: Create a Hardware Events Report Mecanism (HERM)
  i5000_edac: Fix the logic that retrieves memory information
  e752x_edac: provide more info about how DIMMS/ranks are mapped
  edac: Rename the parent dev to pdev
  edac: use Documentation-nano format for some data structs
