Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "This is a large set of updates, mostly for drivers (qla2xxx [including support for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa, be2iscsi, isci, lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas). There's also a rework for tape adding virtually unlimited numbers of tape drives plus a set of dif fixes for sd and a fix for a live lock on hot remove of SCSI devices. This round includes a signed tag pull of isci-for-3.6 Signed-off-by: James Bottomley <JBottomley@Parallels.com>" Fix up trivial conflict in drivers/scsi/qla2xxx/qla_nx.c due to new PCI helper function use in a function that was removed by this pull. * tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (198 commits) [SCSI] st: remove st_mutex [SCSI] sd: Ensure we correctly disable devices with unknown protection type [SCSI] hpsa: gen8plus Smart Array IDs [SCSI] qla4xxx: Update driver version to 5.03.00-k1 [SCSI] qla4xxx: Disable generating pause frames for ISP83XX [SCSI] qla4xxx: Fix double clearing of risc_intr for ISP83XX [SCSI] qla4xxx: IDC implementation for Loopback [SCSI] qla4xxx: update copyrights in LICENSE.qla4xxx [SCSI] qla4xxx: Fix panic while rmmod [SCSI] qla4xxx: Fail probe_adapter if IRQ allocation fails [SCSI] qla4xxx: Prevent MSI/MSI-X falling back to INTx for ISP82XX [SCSI] qla4xxx: Update idc reg in case of PCI AER [SCSI] qla4xxx: Fix double IDC locking in qla4_8xxx_error_recovery [SCSI] qla4xxx: Clear interrupt while unloading driver for ISP83XX [SCSI] qla4xxx: Print correct IDC version [SCSI] qla4xxx: Added new mbox cmd to pass driver version to FW [SCSI] scsi_dh_alua: Enable STPG for unavailable ports [SCSI] scsi_remove_target: fix softlockup regression on hot remove [SCSI] ibmvscsi: Fix host config length field overflow [SCSI] ibmvscsi: Remove backend abstraction ...
