* git://git.kernel.org/pub/scm/linux/kernel/git/bart/linux-hdreg-h-cleanup:
  remove <linux/ata.h> include from <linux/hdreg.h>
  include/linux/hdreg.h: remove unused defines
  isd200: use ATA_* defines instead of *_STAT and *_ERR ones
  include/linux/hdreg.h: cover WIN_* and friends with #ifndef/#endif __KERNEL__
  aoe: WIN_* -> ATA_CMD_*
  isd200: WIN_* -> ATA_CMD_*
  include/linux/hdreg.h: cover struct hd_driveid with #ifndef/#endif __KERNEL__
  xsysace: make it 'struct hd_driveid'-free
  ubd_kern: make it 'struct hd_driveid'-free
  isd200: make it 'struct hd_driveid'-free
