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 ...

- * lpfc_sli4_sp_intr_handler - Slow-path interrupt handler to SLI-4 device

- *
- * This function is directly called from the PCI layer as an interrupt
- * service routine when device with SLI-4 interface spec is enabled with
- * MSI-X multi-message interrupt mode and there are slow-path events in
- * the HBA. However, when the device is enabled with either MSI or Pin-IRQ
- * interrupt mode, this function is called as part of the device-level
- * interrupt handler. When the PCI slot is in error recovery or the HBA is
- * undergoing initialization, the interrupt handler will not process the
- * interrupt. The link attention and ELS ring attention events are handled
- * by the worker thread. The interrupt handler signals the worker thread
- * and returns for these events. This function is called without any lock
- * held. It gets the hbalock to access and update SLI data structures.
- *
- * This function returns IRQ_HANDLED when interrupt is handled else it
- * returns IRQ_NONE.
