Jean Delvare 75135da0d6 i7300_edac: Fix device reference count
pci_get_device() decrements the reference count of "from" (last
argument) so when we break off the loop successfully we have only one
device reference - and we don't know which device we have. If we want
a reference to each device, we must take them explicitly and let
the pci_get_device() walk complete to avoid duplicate references.

This is serious, as over-putting device references will cause
the device to eventually disappear. Without this fix, the kernel
crashes after a few insmod/rmmod cycles.

Tested on an Intel S7000FC4UR system with a 7300 chipset.

Greg Kroah-Hartman 9b3c6e85c2 Drivers: edac: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Mauro Carvalho Chehab 9eb07a7fb8 edac: edac_mc_handle_error(): add an error_count parameter
In order to avoid loosing error events, it is desirable to group
error events together and generate a single trace for several identical
errors.

The trace API already allows reporting multiple errors. Change the
handle_error function to also allow that.

The changes at the drivers were made by this small script:

	$file .=$_ while (<>);
	$file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g;
	print $file;

Mauro Carvalho Chehab 03f7eae80f edac: remove arch-specific parameter for the error handler
Remove the arch-dependent parameter, as it were not used,
as the MCE tracepoint weren't implemented. It probably doesn't
make sense to have an MCE-specific tracepoint, as this will
cost more bytes at the tracepoint, and tracepoint is not free.

The changes at the EDAC drivers were done by this small perl script:

	$file .=$_ while (<>);
	$file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g;

Mauro Carvalho Chehab dd23cd6eb1 edac: Don't add __func__ or __FILE__ for debugf[0-9] msgs
The debug macro already adds that. Most of the work here was
made by this small script:

$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*": /\1"/g;
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*/\1/g;

$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;

$f =~ s/\"MC\: \\n\"/"MC:\\n"/g;

print $f;

After running the script, manual cleanups were done to fix it the remaining
places.

While here, removed the __LINE__ on most places, as it doesn't actually give
useful info on most places.

Mauro Carvalho Chehab 5e2af0c09e edac: Don't initialize csrow's first_page & friends when not needed
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.

Mauro Carvalho Chehab 084a4fccef edac: move dimm properties to struct dimm_info
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.

Michal Marek 152ba39422 edac: Drop __DATE__ usage
The kernel already prints its build timestamp during boot, no need to
repeat it in random drivers and produce different object files each
time.

Jesper Juhl 42b16b3fbb Kill off warning: ‘inline’ is not at beginning of declaration
Fix a bunch of
	warning: ‘inline’ is not at beginning of declaration
messages when building a 'make allyesconfig' kernel with -Wextra.

These warnings are trivial to kill, yet rather annoying when building with
-Wextra.
The more we can cut down on pointless crap like this the better (IMHO).

A previous patch to do this for a 'allnoconfig' build has already been
merged. This just takes the cleanup a little further.

Mauro Carvalho Chehab e6649cc629 i7300_edac: Properly initialize per-csrow memory size
Due to the current edac-core limits, we cannot represent a per-channel
memory size, for FB-DIMM drivers. So, we need to sum-up all values
for each slot, in order to properly represent the total amount of
memory found by the i7300 driver.

Mauro Carvalho Chehab 1aa4a7b6b0 V4L/DVB: i7300_edac: better initialize page counts
It is still somewhat fake, as the pages may not be on this exact order,
and may even be used in mirror mode, but this is a best guess than the
other random fake values.

Mauro Carvalho Chehab 85580ea4f7 i7300_edac: pre-allocate a buffer used to prepare err messages
Instead of dynamically allocating a buffer for it where needed,
just allocate it once. As we'll use the same buffer also during
fatal and non-fatal errors, is is very risky to dynamically allocate
it during an error.
