* and Andre Hedrick <andre@linux-ide.org>
*
* This is the IDE/ATA disk driver, as evolved from hd.c and ide.c.
- *
- * Version 1.00 move disk only code from ide.c to ide-disk.c
- * support optional byte-swapping of all data
- * Version 1.01 fix previous byte-swapping code
- * Version 1.02 remove ", LBA" from drive identification msgs
- * Version 1.03 fix display of id->buf_size for big-endian
- * Version 1.04 add /proc configurable settings and S.M.A.R.T support
- * Version 1.05 add capacity support for ATA3 >= 8GB
- * Version 1.06 get boot-up messages to show full cyl count
- * Version 1.07 disable door-locking if it fails
- * Version 1.08 fixed CHS/LBA translations for ATA4 > 8GB,
- * process of adding new ATA4 compliance.
- * fixed problems in allowing fdisk to see
- * the entire disk.
- * Version 1.09 added increment of rq->sector in ide_multwrite
- * added UDMA 3/4 reporting
- * Version 1.10 request queue changes, Ultra DMA 100
- * Version 1.11 added 48-bit lba
- * Version 1.12 adding taskfile io access method
- * Version 1.13 added standby and flush-cache for notifier
- * Version 1.14 added acoustic-wcache
- * Version 1.15 convert all calls to ide_raw_taskfile
- * since args will return register content.
- * Version 1.16 added suspend-resume-checkpower
- * Version 1.17 do flush on standby, do flush on ATA < ATA6
- * fix wcache setup.
