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;Signed-off-by: Mauro Carvalho Chehab

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;

Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.Acked-by: Chris Metcalf

After this change, it is possible to add sysfs nodes for the DIMM's that

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.Reviewed-by: Aristeu Rozanski

…it slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.Signed-off-by: Tejun Heo <tj@kernel.org>

Refactoring of sysfs code necessitated the refactoring of the edac_mc_alloc()

This patch alters the in tree drivers to utilize this new api signature.Having the index value performed later created a chicken-and-the-egg issue.

edac_mc_add_mc() so that the caller specifies the ID number for the new

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
