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

Pull SCSI fixes from James Bottomley:
 "Nine small fixes.

  The resume fix is a cosmetic removal of a warning with an incorrect
  condition causing it to alarm people wrongly.

  The other eight patches correct a thinko in Christoph Hellwig's DMA
  conversion series. Without it all these drivers end up with 32 bit DMA
  masks meaning they bounce any page over 4GB before sending it to the
  controller.

  Nowadays, even laptops mostly have memory above 4GB, so this can lead
  to significant performance degradation with all the bouncing"
