Cosmetic indentation/formatting cleanup for EDAC code. Make sure we
are using tabs rather than spaces to indent, etc.

Fix EDAC code so EXPORT_SYMBOL comes after the function that is being
exported. This is to maintain consistency with the rest of the kernel.

- 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.

- After we unregister a kobject, wait for our kobject release method
to call complete(). This causes us to wait until the kobject
reference count reaches 0. Otherwise, a task accessing the EDAC
sysfs interface can hold the reference count above 0 until after the
EDAC module has been unloaded. When the reference count finally
drops to 0, this will result in an attempt to call our release
method inside the EDAC module after the module has already been
unloaded.
This isn't the best fix, since a process can get stuck sleeping forever
uninterruptibly if the user does the following:
rmmod my_module < /sys/my_sysfs/file
I'll go back and implement a better fix later. However this should
be ok for now.
- Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather
than from edac_mc_free(). Since edac_mc_add_mc() calls
edac_create_sysfs_mci_device(), edac_mc_del_mc() should call
edac_remove_sysfs_mci_device().

- Remove calls to kobject_init(). These are unnecessary because
kobject_register() calls kobject_init().
- Remove extra calls to kobject_put(). When we call
kobject_unregister(), this releases our reference to the kobject.
The extra calls to kobject_put() may cause the reference count to
drop to 0 while a kobject is still in use.

This is part 2 of a 2-part patch set.
Fix edac_mc_add_mc() so it cleans up properly if call to
edac_create_sysfs_mci_device() fails.

This is part 1 of a 2-part patch set. The code changes are split into
two parts to make the patches more readable.
Move complete_mc_list_del() and del_mc_from_global_list() so we can
call del_mc_from_global_list() from edac_mc_add_mc() without forward
declarations. Perhaps using forward declarations would be better?
I'm doing things this way because the rest of the code is missing
them.

Fix xxx_probe1() functions so they call xxx_get_error_info() functions
to clear initial errors. This is simpler and cleaner than duplicating
the low-level code for accessing PCI config space.

- Disable the EDAC sysfs code. The sysfs interface that EDAC presents to
user space needs more thought, and is likely to change substantially.
Therefore disable it for now so users don't start depending on it in its
current form.
- Disable the default behavior of calling panic() when an uncorrectible
error is detected (since for now, there is no sysfs interface that allows
the user to configure this behavior).

Disable (via ugly #if 0's) the 3 sysfs files that I think by now we all
agree are very much wrong. These files shouldn't become part of the ABI by
the 2.6.16 release, so I rather have this minimal patch merged to disable
them for now, the real fix can then come during the 2.6.17 devel window.

By including version.h edac_mc was rebuilding on every incremental build.
Which defeats the point of incremental builds.

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.
From: doug thompson <norsk5@xmission.com>
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.
