Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 

Pull more SCSI updates from James Bottomley:
 "This is mostly stuff which missed the first pull request because it
  needed to incubate longer.  It's mainly made up of the ncr 5380 rework
  but also has a few assorted bug fixes"

ST-DMA, replacing ACSI). It does NOT support other schemes, like
in the Hades (without DMA).
config ATARI_SCSI_TOSHIBA_DELAY
bool "Long delays for Toshiba CD-ROMs"
depends on ATARI_SCSI
help
This option increases the delay after a SCSI arbitration to
accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
use a Toshiba CD-ROM drive; otherwise, the option is not needed and
would impact performance a bit, so say N.
config ATARI_SCSI_RESET_BOOT
bool "Reset SCSI-devices at boottime"
depends on ATARI_SCSI
help
Reset the devices on your Atari whenever it boots. This makes the
boot process fractionally longer but may assist recovery from errors
that leave the devices with SCSI operations partway completed.
config MAC_SCSI
tristate "Macintosh NCR5380 SCSI"
depends on MAC && SCSI=y
