Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull late SCSI updates from James Bottomley: "This is mostly stuff which missed the initial pull. There's a new driver: qedi, and some ufs, ibmvscsis and ncr5380 updates plus some assorted driver fixes and also a fix for the bug where if a device goes into a blocked state between configuration and sysfs device add (which can be a long time under async probing) it would become permanently blocked" * tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (30 commits) scsi: avoid a permanent stop of the scsi device's request queue scsi: mpt3sas: Recognize and act on iopriority info scsi: qla2xxx: Fix Target mode handling with Multiqueue changes. scsi: qla2xxx: Add Block Multi Queue functionality. scsi: qla2xxx: Add multiple queue pair functionality. scsi: qla2xxx: Utilize pci_alloc_irq_vectors/pci_free_irq_vectors calls. scsi: qla2xxx: Only allow operational MBX to proceed during RESET. scsi: hpsa: remove memory allocate failure message scsi: Update 3ware driver email addresses scsi: zfcp: fix rport unblock race with LUN recovery scsi: zfcp: do not trace pure benign residual HBA responses at default level scsi: zfcp: fix use-after-"free" in FC ingress path after TMF scsi: libcxgbi: return error if interface is not up scsi: cxgb4i: libcxgbi: add missing module_put() scsi: cxgb4i: libcxgbi: cxgb4: add T6 iSCSI completion feature scsi: cxgb4i: libcxgbi: add active open cmd for T6 adapters scsi: cxgb4i: use cxgb4_tp_smt_idx() to get smt_idx scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework. scsi: aacraid: remove wildcard for series 9 controllers scsi: ibmvscsi: add write memory barrier to CRQ processing ...

 This file documents the NCR53c400 extensions by Kevin Lentin and some
 enhancements to the NCR5380 core.

-This driver supports both NCR5380 and NCR53c400 cards in port or memory
-mapped modes. Currently this driver can only support one of those mapping
-modes at a time but it does support both of these chips at the same time.
-The next release of this driver will support port & memory mapped cards at
-the same time. It should be able to handle multiple different cards in the
-same machine.
+This driver supports NCR5380 and NCR53c400 and compatible cards in port or
+memory mapped modes.

-The drivers/scsi/Makefile has an override in it for the most common
-NCR53c400 card, the Trantor T130B in its default configuration:
-	Port: 0x350
-	IRQ : 5
+Use of an interrupt is recommended, if supported by the board, as this will
+allow targets to disconnect and thereby improve SCSI bus utilization.
+
+If the irq parameter is 254 or is omitted entirely, the driver will probe
+for the correct IRQ line automatically. If the irq parameter is 0 or 255
+then no IRQ will be used.

 The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
 supported by the driver.

-             and HP C2502 at 0x300 with IRQ 7
