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

Pull first round of SCSI updates from James Bottomley:
 "The patch set is mostly driver updates (usf, zfcp, lpfc, mpt2sas,
  megaraid_sas, bfa, ipr) and a few bug fixes.  Also of note is that the
  Buslogic driver has been rewritten to a better coding style and 64 bit
  support added.  We also removed the libsas limitation on 16 bytes for
  the command size (currently no drivers make use of this)"

+* Universal Flash Storage (UFS) Host Controller
+
+UFSHC nodes are defined to describe on-chip UFS host controllers.
+Each UFS controller instance should have its own node.
+
+Required properties:
+- compatible        : compatible list, contains "jedec,ufs-1.1"
+- interrupts        : <interrupt mapping for UFS host controller IRQ>
+- reg               : <registers mapping>
+
+Example:
+	ufshc@0xfc598000 {
+		compatible = "jedec,ufs-1.1";
+		reg = <0xfc598000 0x800>;
+		interrupts = <0 28 0>;

+# lpfc_max_luns: maximum allowed LUN ID. This is the highest LUN ID that
+#    will be scanned by the SCSI midlayer when sequential scanning is
+#    used; and is also the highest LUN ID allowed when the SCSI midlayer
+#    parses REPORT_LUN responses. The lpfc driver has no LUN count or
+#    LUN ID limit, but the SCSI midlayer requires this field for the uses
+#    above. The lpfc driver limits the default value to 255 for two reasons.
+#    As it bounds the sequential scan loop, scanning for thousands of luns
+#    on a target can take minutes of wall clock time.  Additionally,
+#    there are FC targets, such as JBODs, that only recognize 8-bits of
+#    LUN ID. When they receive a value greater than 8 bits, they chop off
+#    the high order bits. In other words, they see LUN IDs 0, 256, 512,
+#    and so on all as LUN ID 0. This causes the linux kernel, which sees
+#    valid responses at each of the LUN IDs, to believe there are multiple
+#    devices present, when in fact, there is only 1.
+#    A customer that is aware of their target behaviors, and the results as
+#    indicated above, is welcome to increase the lpfc_max_luns value.
+#    As mentioned, this value is not used by the lpfc driver, only the
