Hi,

More "uninteresting" IDE changes:

- make all host drivers use struct ide_port_info
- sanitize command/request completion API
- replace ide_task_t by struct ide_cmd
- improve debugging scheme (from Borislav Petkov)
- misc fixes/cleanups

Linus, please pull from:

master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/
