* git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6: (100 commits)
  ide: move hwif_register() call out of ide_probe_port()
  ide: factor out code for tuning devices from ide_probe_port()
  ide: move handling of I/O resources out of ide_probe_port()
  ide: make probe_hwif() return an error value
  ide: use ide_remove_port_from_hwgroup in init_irq()
  ide: prepare init_irq() for using ide_remove_port_from_hwgroup()
  ide: factor out code removing port from hwgroup from ide_unregister()
  ide: I/O resources are released too early in ide_unregister()
  ide: cleanup ide_system_bus_speed()
  ide: remove needless zeroing of hwgroup fields from init_irq()
  ide: remove unused ide_hwgroup_t fields
  ide_platform: remove struct hwif_prop
  ide: remove hwif->present manipulations from hwif_init()
  ide: move wait_hwif_ready() documentation in the right place
  ide: fix handling of busy I/O resources in probe_hwif()
  <linux/hdsmart.h> is not used by kernel code
  ide: don't include <linux/hdsmart.h>
  ide-floppy: cleanup header
  ide: update/add my Copyrights
  ide: delete filenames/versions from comments
