Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6
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. [SCSI] qla4xxx: Export CHAP index as sysfs attribute [SCSI] scsi_transport: Export CHAP index as sysfs attribute [SCSI] qla4xxx: Add support to display CHAP list and delete CHAP entry [SCSI] iscsi_transport: Add support to display CHAP list and delete CHAP entry [SCSI] pm8001: fix endian issue with code optimization. [SCSI] pm8001: Fix possible racing condition. [SCSI] pm8001: Fix bogus interrupt state flag issue. [SCSI] ipr: update PCI ID definitions for new adapters [SCSI] qla2xxx: handle default case in qla2x00_request_firmware() [SCSI] isci: improvements in driver unloading routine [SCSI] isci: improve phy event warnings [SCSI] isci: debug, provide state-enum-to-string conversions [SCSI] scsi_transport_sas: 'enable' phys on reset [SCSI] libsas: don't recover end devices attached to disabled phys [SCSI] libsas: fixup target_port_protocols for expanders that don't report sata [SCSI] libsas: set attached device type and target protocols for local phys ...
