SCSI updates from James Bottomley: "The update includes the usual assortment of driver updates (lpfc, qla2xxx, qla4xxx, bfa, bnx2fc, bnx2i, isci, fcoe, hpsa) plus a huge amount of infrastructure work in the SAS library and transport class as well as an iSCSI update. There's also a new SCSI based virtio driver." * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (177 commits) [SCSI] qla4xxx: Update driver version to 5.02.00-k15 [SCSI] qla4xxx: trivial cleanup [SCSI] qla4xxx: Fix sparse warning [SCSI] qla4xxx: Add support for multiple session per host.
