Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6
Pull SCSI updates from James Bottomley: "This is primarily another round of driver updates (lpfc, bfa, fcoe, ipr) plus a new ufshcd driver. There shouldn't be anything controversial in here (The final deletion of scsi proc_ops which caused some build breakage has been held over until the next merge window to give us more time to stabilise it). I'm afraid, with me moving continents at exactly the wrong time, anything submitted after the merge window opened has been held over to the next merge window." * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (63 commits) [SCSI] ipr: Driver version 2.5.3 [SCSI] ipr: Increase alignment boundary of command blocks [SCSI] ipr: Increase max concurrent oustanding commands [SCSI] ipr: Remove unnecessary memory barriers [SCSI] ipr: Remove unnecessary interrupt clearing on new adapters [SCSI] ipr: Fix target id allocation re-use problem [SCSI] atp870u, mpt2sas, qla4xxx use pci_dev->revision [SCSI] fcoe: Drop the rtnl_mutex before calling fcoe_ctlr_link_up [SCSI] bfa: Update the driver version to 3.0.23.0 [SCSI] bfa: BSG and User interface fixes. [SCSI] bfa: Fix to avoid vport delete hang on request queue full scenario. [SCSI] bfa: Move service parameter programming logic into firmware. [SCSI] bfa: Revised Fabric Assigned Address(FAA) feature implementation. [SCSI] bfa: Flash controller IOC pll init fixes. [SCSI] bfa: Serialize the IOC hw semaphore unlock logic. [SCSI] bfa: Modify ISR to process pending completions [SCSI] bfa: Add fc host issue lip support [SCSI] mpt2sas: remove extraneous sas_log_info messages [SCSI] libfc: fcoe_transport_create fails in single-CPU environment [SCSI] fcoe: reduce contention for fcoe_rx_list lock [v2] ...
