EDAC: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

EDAC: Replace EDAC_DIMM_PTR() macro with edac_get_dimm() function

The EDAC_DIMM_PTR() macro takes 3 arguments from struct mem_ctl_info.
Clean up this interface to only pass the mci struct and replace this
macro with a new function edac_get_dimm().

Also introduce an edac_get_dimm_by_index() function for later use.
This allows it to get a DIMM pointer only by a given index. This can
be useful if the DIMM's position within the layers of the memory
controller or the exact size of the layers are unknown.

Small style changes made for some hunks after applying the semantic
patch.

Semantic patch used:

@@ expression mci, a, b,c; @@

-EDAC_DIMM_PTR(mci->layers, mci->dimms, mci->n_layers, a, b, c)
+edac_get_dimm(mci, a, b, c)

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.

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;

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;

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

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.

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.

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.

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.

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.

i7300_edac: Cleanup: reorganize the file contents

This change should do no functional change. It just rearranges the

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.

i7300_edac: Cleanup: remove get_error_info logic

As the error logic in this driver came from i5400 driver, it
were using one function to get errors, and another to display.
Let's make it simpler and avoid doing it into two steps.

There's no mention at the datasheet about how to enable global error
