[PATCH] PCI: Bus Parity Status sysfs interface

From: Doug Thompson <norsk5@yahoo.com>

This patch adds the 'broken_parity_status' sysfs attribute file to a PCI device.
Reading this attribute a userland program can determine if PCI device provides false
positives (value of 1) in its generation of PCI Parity status, or not (value of 0).
As PCI devices are found to be 'bad' in this regard, userland programs can also set
the appropriate value (root access only) of a faulty device. This per device
information will be used in the EDAC PCI Parity scanner code in a future patch once
this interface becomes available.
