SCSI misc on 20130702 

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>;
};

# 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
# SCSI midlayer.
# Value range is [0,65535]. Default value is 255.
# NOTE: The SCSI layer might probe all allowed LUN on some old targets.
