2007-07-19drivers/edac: fix edac_device sysfs corner case bugDoug Thompson
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.

2007-07-19drivers/edac: fix edac_device sysfs completion codeDouglas Thompson
With feedback, this patch corrects operation of the kobject release operation on kobjects, attributes and controls for the edac_device.

2007-07-19drivers/edac: fix leaf sysfs attributeDouglas Thompson
This patch fixes and enhances the driver level set of sysfs attributes that can be added to the 'block' level of an edac_device type of driver. There is a controller information structure, which contains one or more instances of device. Each instance will have one or more blocks of device specific counters. This patch fixes the ability to have more detailed attributes/controls for each of the 'blocks', providing for the addition of controls/attributes from the low level driver to user space via sysfs.

2007-07-19drivers/edac: cleanup spaces-gotos after Lindent messupDouglas Thompson
This patch fixes some remnant spaces inserted by the use of Lindent. Seems Lindent adds some spaces when it shoulded. These have been fixed. In addition, goto targets have issues, these have been fixed in this patch.

2007-07-19drivers/edac: add device sysfs attributesDouglas Thompson
Added new controls for the edac_device and edac_mc sysfs folder.

2007-07-19drivers/edac: add edac_device classDouglas Thompson
This patch adds the new 'class' of object to be managed, named: 'edac_device'. As a peer of the 'edac_mc' class of object, it provides a non-memory centric view of an ERROR DETECTING device in hardware. It provides a sysfs interface and an abstraction for varioius EDAC type devices. Multiple 'instances' within the class are possible, with each 'instance' able to have multiple 'blocks', and each 'block' having 'attributes'. At the 'block' level there are the 'ce_count' and 'ue_count' fields which the device driver can update and/or call edac_device_handle_XX() functions. At each higher level are additional 'total' count fields, which are a summation of counts below that level. This 'edac_device' has been used to capture and present ECC errors which are found in a a L1 and L2 system on a per CORE/CPU basis.
