Collection of patches, merged into one, from Adrian that do the following:

1) This patch makes the following needlessly global functions static:
- edac_pci_get_log_pe()
- edac_pci_get_log_npe()
- edac_pci_get_panic_on_pe()
- edac_pci_unregister_sysfs_instance_kobj()
- edac_pci_main_kobj_setup()

2) Remove unneeded function edac_device_find()

3) Added #if 0 around function  edac_pci_find()

4) make the needlessly global edac_pci_generic_check() static

5) Removed function edac_check_mc_devices()

Doug Thompson modified Adrian's patches, to bettern represent
the direction of EDAC, and make them one patch.

Add a module parameter "sysbus_parity" to allow forcing system bus parity
error checking on or off.  Also add support to automatically disable system
bus parity errors for processors which do not support it.

If the sysbus_parity parameter is specified, sysbus parity detection will be
forced on or off.  If it is not specified, the driver will attempt to look at
the CPU identifier string and determine if the CPU supports system bus parity.
 A blacklist was used instead of a whitelist so that system bus parity would
be enabled by default and to minimize the chances of breaking things for those
people already using the driver which for some reason have a processor that
does not have a valid CPU identifier string.

Using the EDAC code in kernel.org kernel version 2.6.23.8 I am seeing the
following problem:

    In the kernel there is a pci device attribute located in sysfs that is
    checked by the EDAC PCI scanning code. If that attribute is set,
    PCI parity/error scannining is skipped for that device. The attribute
    is:

            broken_parity_status

    as is located in /sys/devices/pci<XXX>/0000:XX:YY.Z directorys for
    PCI devices.

I don't think this check was actually implemented.  I have a misbehaved card
that reports a parity error every 1000 ms:

Nov 25 07:28:43 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0
Nov 25 07:28:44 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0
Nov 25 07:28:45 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0

Setting that card's broken_parity_status bit did not mask the error:

echo "1" > /sys/bus/pci/devices/0000:05:01.0/broken_parity_status

I looked through the EDAC code and did not readily see any reference to
broken_parity_status at all (which makes sense based on the behavior I am
seeing).  I applied the following patch as a proof-of-concept and now EDAC's
PCI parity error reporting behaves as documented:

Good regression find, bryan. It used to work. sigh.
I added more logic to your patch, for more coverage of the error.

We don't need a "default" ktype for a kset.  We should set this
explicitly every time for each kset.  This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.

This patch is based on a lot of help from Kay Sievers.

This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner
and the previous fixes for EDAC_MC and EDAC_DEVICE.

It removes the old (and incorrect) completion model and uses reference counts
on per instance kobjects and on the edac core module.

This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI
code was missed.  In addition, this fixes a system hang after a low level
driver was unloaded.  (A cleanup function was called twice, which really
screwed things up)

This fixes a deadlock that could occur on a 'setup' and 'teardown' sequence of
the workq for a edac_mc control structure instance.  A similiar fix was
previously implemented for the edac_device code.

In addition, the edac_mc device code there was missing code to allow the workq
period valu to be altered via sysfs control.

This patch adds that fix on the code, and allows for the changing of the
period value as well.

Some simple fixes to properly reference counter values from the block
attribute level of edac_device objects.  Properly sequencing the array pointer
was added, resulting in correct identification of block level attributes from
their base class functions.

Added more verbose debug statement for event tracking.

Also during some corner testing, found a bug in the store/show sequence
of operations for the block attribute/controls management.

An old intermediate structure for 'blocks' was still in the processing
pipeline.  This patch removes that old structure and correctly utilizes the
new struct edac_dev_sysfs_block_attribute for passing control from the sysfs
to the low level store/show function of the edac driver.

Now the proper kobj pointer to passed downward to the store/show
functions.

This patch refactors the 'releasing' of kobjects for the edac_mc type of
device.  The correct pattern of kobject release is followed.

As internal kobjs are allocated they bump a ref count on the top level kobj.
It in turn has a module ref count on the edac_core module.  When internal
kobjects are released, they dec the ref count on the top level kobj.  When the
top level kobj reaches zero, it decrements the ref count on the edac_core
object, allow it to be unloaded, as all resources have all now been released.
