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

As EDAC doesn't use struct device itself, it created a parent dev
pointer called as "pdev". Now that we'll be converting it to use
struct device, instead of struct devsys, this needs to be fixed.No functional changes.

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.Reviewed-by: Aristeu Rozanski

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

These const tables are currently marked __devinitdata, but
Documentation/PCI/pci.txt says:"o The ID table array should be marked __devinitconst; this is done
automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE()."So use DEFINE_PCI_DEVICE_TABLE(x).

…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>

I implemented opstate_init() as a inline function in linux/edac.h.
added calling opstate_init() to:
i82443bxgx_edac.c
i82860_edac.c
i82875p_edac.c
i82975x_edac.cI wrote a fixed patch of
edac-fix-module-initialization-on-several-modules.patch,
and tested building 2.6.25-rc7 with applying this. It was succeed.
I think the patch is now correct.Cc: Alan Cox

Refactoring of sysfs code necessitated the refactoring of the edac_mc_alloc()
and edac_mc_add_mc() apis, of moving the index value to the alloc() function.
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.
Moving it to the alloc() function allows for creating the necessary sysfs
entries with the proper index numberCc: Alan Cox alan@lxorguk.ukuu.org.uk
