  sg_init_table() should use unsigned loop index variable
  sg_last() should use unsigned loop index variable
  Initialise scatter/gather list in sg driver
  Initialise scatter/gather list in ata_sg_setup
  x86: fix pci-gart failure handling
  SG: s390-scsi: missing size parameter in zfcp_address_to_sg()
  SG: clear termination bit in sg_chain()
