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

Pull SCSI fixes from James Bottomley:
 "This is a set of five fixes: Two MAINTAINER email updates (urgent
  because the non-avagotech emails will start bouncing) an lpfc big
  endian oops fix, a 256 byte sector hang fix (to eliminate 256 byte
  sectors) and a storvsc fix which could cause test unit ready failures
  on bringup"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  MAINTAINERS: Revise lpfc maintainers for Avago Technologies ownership of Emulex
  MAINTAINERS, be2iscsi: change email domain
  sd: Disable support for 256 byte/sector disks
  lpfc: Fix breakage on big endian kernels
  storvsc: Set the SRB flags correctly when no data transfer is needed
