 	  EDAC is designed to report errors in the core system.
 	  These are low-level errors that are reported in the CPU or
 	  supporting chipset: memory errors, cache errors, PCI errors,
 	  thermal throttling, etc..  If unsure, select 'Y'.
 
+	  If this code is reporting problems on your system, please
+	  see the EDAC project web pages for more information at:
+
+	  <http://bluesmoke.sourceforge.net/>
+
+	  and:
+
+	  <http://buttersideup.com/edacwiki>
+
+	  There is also a mailing list for the EDAC project, which can
+	  be found via the sourceforge page.

- * The internal buffer is meant to store obaque blobs of data, so it doesn't
- * know of higher level concepts like triggers.
- * It consists of a number of pages that are used as a ringbuffer. Each data
- * blob is stored in a simple record that consists of an integer, which
- * contains the size of the following data, and the data bytes themselfes.
- *
- * To allow for multiple independent readers we create one internal buffer
- * each time the device is opened and destroy the buffer when the file is
- * closed again.
- *
- * One record can be written to a buffer by using the functions
- * - dasd_eer_start_record (one time per record to write the size to the buffer
- *                          and reserve the space for the data)
- * - dasd_eer_write_buffer (one or more times per record to write the data)
- * The data can be written in several steps but you will have to compute
- * the total size up front for the invocation of dasd_eer_start_record.
- * If the ringbuffer is full, dasd_eer_start_record will remove the required
- * number of old records.
- *
- * A record is typically read in two steps, first read the integer that
- * specifies the size of the following data, then read the data.
- * Both can be done by
- * - dasd_eer_read_buffer
- *
- * For all mentioned functions you need to get the bufferlock first and keep it
- * until a complete record is written or read.
- */

-/*
- * Alle information necessary to keep track of an internal buffer is kept in
- * a struct eerbuffer. The buffer specific to a file pointer is strored in
- * the private_data field of that file. To be able to write data to all
- * existing buffers, each buffer is also added to the bufferlist.
- * If the user doesn't want to read a complete record in one go, we have to
- * keep track of the rest of the record. residual stores the number of bytes
- * that are still to deliver. If the rest of the record is invalidated between
- * two reads then residual will be set to -1 so that the next read will fail.
- * All entries in the eerbuffer structure are protected with the bufferlock.
- * To avoid races between writing to a buffer on the one side and creating
- * and destroying buffers on the other side, the bufferlock must also be used
- * to protect the bufferlist.

-/*****************************************************************************/
-
-/*
- * When a DASD device driver wants to report an error, it calls the
- * function dasd_eer_write_trigger (via a notifier mechanism) and gives the
- * respective trigger ID as parameter.
- * Currently there are four kinds of triggers:
- *
- * DASD_EER_FATALERROR:  all kinds of unrecoverable I/O problems
- * DASD_EER_PPRCSUSPEND: PPRC was suspended
- * DASD_EER_NOPATH:      There is no path to the device left.
- * DASD_EER_STATECHANGE: The state of the device has changed.
- *
- * For the first three triggers all required information can be supplied by
- * the caller. For these triggers a record is written by the function
- * dasd_eer_write_standard_trigger.
- *
- * When dasd_eer_write_trigger is called to write a DASD_EER_STATECHANGE
- * trigger, we have to gather the necessary sense data first. We cannot queue
- * the necessary SNSS (sense subsystem status) request immediatly, since we
- * are likely to run in a deadlock situation. Instead, we schedule a
- * work_struct that calls the function dasd_eer_sense_subsystem_status to
- * create and start an SNSS  request asynchronously.
- *
- * To avoid memory allocations at runtime, the necessary memory is allocated
- * when the extended error reporting is enabled for a device (by
- * dasd_eer_probe). There is one private eer data structure for each eer
- * enabled DASD device. It contains memory for the work_struct, one SNSS cqr
- * and a flags field that is used to coordinate the use of the cqr. The call
- * to write a state change trigger can come in at any time, so we have one flag
- * CQR_IN_USE that protects the cqr itself. When this flag indicates that the
- * cqr is currently in use, dasd_eer_sense_subsystem_status cannot start a
- * second request but sets the SNSS_REQUESTED flag instead.
- *
- * When the request is finished, the callback function dasd_eer_SNSS_cb
- * is called. This function will invoke the function
- * dasd_eer_write_SNSS_trigger to finally write the trigger. It will also
- * check the SNSS_REQUESTED flag and if it is set it will call
- * dasd_eer_sense_subsystem_status again.
- *
- * To avoid race conditions during the handling of the lock, the flags must
- * be protected by the snsslock.
