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.c
I 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.

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 number

If ERRSTS indicates that there's no error then we don't need to bother reading
the other registers.
In addition to making the common case faster, this actually fixes a small race
where we don't see an error but we clear the error bits anyway, potentially
wiping away info on an error that happened in the interim (or where a CE
arrives between the first and second read of ERRSTS, causing us to falsely
claim "UE overwrote CE").

Move dev_name() macro to a more generic interface since it's not possible
to determine whether a device is pci, platform, or of_device easily.
Now each low level driver sets the name into the control structure, and

The 82875 EDAC driver enables an otherwise-hidden PCI device, but doesn't
register it as a PCI device properly. Therefore, the device list in
/proc/bus/pci/devices is different than the tree in /sys/bus/pci. This
usually manifests as the X server failing to start, since it expects the
two lists to be consistent.

Remove add_mc_to_global_list(). In next patch, this function will be
reimplemented with different semantics.
1 Reimplement add_mc_to_global_list() with semantics that allow the caller to
determine the ID number for a mem_ctl_info structure. Then modify
edac_mc_add_mc() so that the caller specifies the ID number for the new
mem_ctl_info structure. Platform-specific code should be able to assign the
ID numbers in a platform-specific manner. For instance, on Opteron it makes
sense to have the ID of the mem_ctl_info structure match the ID of the node
that the memory controller belongs to.
2 Modify callers of edac_mc_add_mc() so they use the new semantics.

Now each driver has its own local string.
Remove some PCI dependencies from the core EDAC module. Made the code 'struct
device' centric instead of 'struct pci_dev' Most of the code changes here are
from a patch by Dave Jiang. It may be best to eventually move the
PCI-specific code into a separate source file.

- Fix code so we always hold mem_ctls_mutex while we are stepping
through the list of mem_ctl_info structures. Otherwise bad things
may happen if one task is stepping through the list while another
task is modifying it. We may eventually want to use reference
counting to manage the mem_ctl_info structures. In the meantime we
may as well fix this bug.
- Don't disable interrupts while we are walking the list of
mem_ctl_info structures in check_mc_devices(). This is unnecessary.

This is a subset of the bluesmoke project core code, stripped of the NMI work
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.

This converts EDAC to sysfs and is the final chunk neccessary before EDAC
has a stable user space API and can be considered for submission into the
base kernel.
