The logic there is broken: it basically creates two csrows for
each DIMM and assumes that all DIMM's are dual rank. Only one of
the csrows will contain the entire DIMM size. If single rank
memories are found, they'll be marked with 0 bytes.
The check if the AMB is present were also wrong.
Yet, as the error reports don't use the memory size in order to
credit an error to the right DIMM, that part of the driver seems
to work. That's why probably nobody detected the issue yet.
After this patch, the memory layout is now properly reported,
when debug mode is enabled, and the number of ranks per dimm is
now shown:
calculate_dimm_size: ----------------------------------------------------------
calculate_dimm_size: slot 3 0 MB | 0 MB | 0 MB | 0 MB |
calculate_dimm_size: slot 2 0 MB | 0 MB | 0 MB | 0 MB |
calculate_dimm_size: ----------------------------------------------------------
calculate_dimm_size: slot 1 0 MB | 0 MB | 0 MB | 0 MB |
calculate_dimm_size: slot 0 512 MB 1R| 512 MB 1R| 512 MB 1R| 512 MB 1R|
calculate_dimm_size: ----------------------------------------------------------
calculate_dimm_size: channel 0 | channel 1 | channel 2 | channel 3 |
calculate_dimm_size: branch 0 | branch 1 |
(1R above means that all memories on my test machine are single-ranked)

While userspace doesn't fill the dimm labels, add there the dimm location,
as described by the used memory model. This could eventually match what
is described at the dmidecode, making easier for people to identify the
memory.
For example, on an Intel motherboard where the DMI table is reliable,
the first memory stick is described as:
Memory Device
Array Handle: 0x0029
Error Information Handle: Not Provided
Total Width: 64 bits
Data Width: 64 bits
Size: 2048 MB
Form Factor: DIMM
Set: 1
Locator: A1_DIMM0
Bank Locator: A1_Node0_Channel0_Dimm0
Type: <OUT OF SPEC>
Type Detail: Synchronous
Speed: 800 MHz
Manufacturer: A1_Manufacturer0
Serial Number: A1_SerNum0
Asset Tag: A1_AssetTagNum0
Part Number: A1_PartNum0
The memory named as "A1_DIMM0" is physically located at the first
memory controller (node 0), at channel 0, dimm slot 0.
After this patch, the memory label will be filled with:
/sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0
And (after the new EDAC API patches) as:
/sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0
So, even if the memory label is not initialized on userspace, an useful
information with the error location is filled there, expecially since
several systems/motherboards are provided with enough info to map from
channel/slot (or branch/channel/slot) into the DIMM label. So, letting the
EDAC core fill it by default is a good thing.
It should noticed that, as the label filling happens at the
edac_mc_alloc(), drivers can override it to better describe the memories
(and some actually do it).

Change the EDAC internal representation to work with non-csrow
based memory controllers.
There are lots of those memory controllers nowadays, and more
are coming. So, the EDAC internal representation needs to be
changed, in order to work with those memory controllers, while
preserving backward compatibility with the old ones.
The edac core was written with the idea that memory controllers
are able to directly access csrows.
This is not true for FB-DIMM and RAMBUS memory controllers.
Also, some recent advanced memory controllers don't present a per-csrows
view. Instead, they view memories as DIMMs, instead of ranks.
So, change the allocation and error report routines to allow
them to work with all types of architectures.
This will allow the removal of several hacks with FB-DIMM and RAMBUS
memory controllers.
Also, several tests were done on different platforms using different
x86 drivers.
TODO: a multi-rank DIMMs are currently represented by multiple DIMM
entries in struct dimm_info. That means that changing a label for one
rank won't change the same label for the other ranks at the same DIMM.
This bug is present since the beginning of the EDAC, so it is not a big
deal. However, on several drivers, it is possible to fix this issue, but
it should be a per-driver fix, as the csrow => DIMM arrangement may not
be equal for all. So, don't try to fix it here yet.
I tried to make this patch as short as possible, preceding it with
several other patches that simplified the logic here. Yet, as the
internal API changes, all drivers need changes. The changes are
generally bigger in the drivers for FB-DIMMs.

The edac core were written with the idea that memory controllers
are able to directly access csrows, and that the channels are
used inside a csrows select.
This is not true for FB-DIMM and RAMBUS memory controllers.
Also, some recent advanced memory controllers don't present a per-csrows
view. Instead, they view memories as DIMMs, instead of ranks, accessed
via csrow/channel.
So, changes are needed in order to allow the EDAC core to
work with all types of architectures.
In preparation for handling non-csrows based memory controllers,
add some memory structs and a macro:
enum hw_event_mc_err_type: describes the type of error
(corrected, uncorrected, fatal)
To be used by the new edac_mc_handle_error function;
enum edac_mc_layer: describes the type of a given memory
architecture layer (branch, channel, slot, csrow).
struct edac_mc_layer: describes the properties of a memory
layer (type, size, and if the layer
will be used on a virtual csrow.
EDAC_DIMM_PTR() - as the number of layers can vary from 1 to 3,
this macro converts from an address with up to 3 layers into
a linear address.

The edac_align_ptr() function is used to prepare data for a single
memory allocation kzalloc() call. It counts how many bytes are needed
by some data structure.
Using it as-is is not that trivial, as the quantity of memory elements
reserved is not there, but, instead, it is on a next call.
In order to avoid mistakes when using it, move the number of allocated
elements into it, making easier to use it.

The number of pages is a dimm property. Move it to the dimm struct.
After this change, it is possible to add sysfs nodes for the DIMM's that
will properly represent the DIMM stick properties, including its size.
A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when
the memory controller represents the memory via chip select rows.

Almost all edac drivers initialize csrow_info->first_page,
csrow_info->last_page and csrow_info->page_mask. Those vars are
used inside the EDAC core, in order to calculate the csrow affected
by an error, by using the routine edac_mc_find_csrow_by_page().
However, very few drivers actually use it:
e752x_edac.c
e7xxx_edac.c
i3000_edac.c
i82443bxgx_edac.c
i82860_edac.c
i82875p_edac.c
i82975x_edac.c
r82600_edac.c
There also a few other drivers that have their own calculus
formula internally using those vars.
All the others are just wasting time by initializing those
data.
While initializing data without using them won't cause any troubles, as
those information is stored at the wrong place (at csrows structure), it
is better to remove what is unused, in order to simplify the next patch.

On systems based on chip select rows, all channels need to use memories
with the same properties, otherwise the memories on channels A and B
won't be recognized.
However, such assumption is not true for all types of memory
controllers.
Controllers for FB-DIMM's don't have such requirements.
Also, modern Intel controllers seem to be capable of handling such
differences.
So, we need to get rid of storing the DIMM information into a per-csrow
data, storing it, instead at the right place.
The first step is to move grain, mtype, dtype and edac_mode to the
per-dimm struct.

The way a DIMM is currently represented implies that they're
linked into a per-csrow struct. However, some drivers don't see
csrows, as they're ridden behind some chip like the AMB's
on FBDIMM's, for example.
This forced drivers to fake^Wvirtualize a csrow struct, and to create
a mess under csrow/channel original's concept.
Move the DIMM labels into a per-DIMM struct, and add there
the real location of the socket, in terms of csrow/channel.
Latter patches will modify the location to properly represent the
memory architecture.
All other drivers will use a per-csrow type of location.
Some of those drivers will require a latter conversion, as
they also fake the csrows internally.
TODO: While this patch doesn't change the existing behavior, on
csrows-based memory controllers, a csrow/channel pair points to a memory
rank. There's a known bug at the EDAC core that allows having different
labels for the same DIMM, if it has more than one rank. A latter patch
is need to merge the several ranks for a DIMM into the same dimm_info
struct, in order to avoid having different labels for the same DIMM.
The edac_mc_alloc() will now contain a per-dimm initialization loop that
will be changed by latter patches in order to match other types of
memory architectures.

We're already invalidating the data cache, and setting the new change
attribute. Since directories don't care about the i_size field, there
is no need to be forcing any extra revalidation of the page cache.
We do keep the NFS_INO_INVALID_ATTR flag, in order to force an
attribute cache revalidation on stat() calls since we do not
update the mtime and ctime fields.
