Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This is the usual grab bag of driver updates (lpfc, hpsa, megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates. There is also one new driver: the Cisco snic. The advansys driver has been rewritten to get rid of the warning about converting it to the DMA API, the tape statistics patch got in and finally, there's a resuffle of SCSI header files to separate more cleanly initiator from target mode (and better share the common definitions)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (156 commits) snic: driver for Cisco SCSI HBA qla2xxx: Fix indentation qla2xxx: Comment out unreachable code fusion: remove dead MTRR code advansys: fix compilation errors and warnings when CONFIG_PCI is not set mptsas: fix depth param in scsi_track_queue_full megaraid: fix irq setup process regression lpfc: Update version to 10.7.0.0 for upstream patch set. lpfc: Fix to drop PLOGIs from fabric node till LOGO processing completes lpfc: Fix scsi task management error message. lpfc: Fix cq_id masking problem. lpfc: Fix scsi prep dma buf error. lpfc: Add support for using block multi-queue lpfc: Devices are not discovered during takeaway/giveback testing lpfc: Fix vport deletion failure. lpfc: Check for active portpeerbeacon. lpfc: Update driver version for upstream patch set 10.6.0.1. lpfc: Change buffer pool empty message to miscellaneous category lpfc: Fix incorrect log message reported for empty FCF record. lpfc: Fix rport leak. ...
