Pull final round of SCSI updates from James Bottomley:
 "Sorry for the delay in this patch which was mostly caused by getting
  the merger of the mpt2/mpt3sas driver, which was seen as an essential
  item of maintenance work to do before the drivers diverge too much.
  Unfortunately, this caused a compile failure (detected by linux-next),
  which then had to be fixed up and incubated.

  In addition to the mpt2/3sas rework, there are updates from pm80xx,
  lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
  an assortment of changes including some year 2038 issues, a fix for a
  remove before detach issue in some drivers and a couple of other minor
  issues"

+               default). If DEBUG is set to 0 then this file will not
+               appear in sysfs as its presence is conditional upon debug
+               output support being compiled into the module.

- *  10-31-07  02.00.01  Fixed name for pMpi2SCSITaskManagementRequest_t.
- *  12-18-07  02.00.02  Modified Task Management Target Reset Method defines.
- *  02-29-08  02.00.03  Added Query Task Set and Query Unit Attention.
- *  03-03-08  02.00.04  Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
- *  05-21-08  02.00.05  Fixed typo in name of Mpi2SepRequest_t.
- *  10-02-08  02.00.06  Removed Untagged and No Disconnect values from SCSI IO
- *                      Control field Task Attribute flags.
- *                      Moved LUN field defines to mpi2.h because they are
- *                      common to many structures.
- *  05-06-09  02.00.07  Changed task management type of Query Unit Attention to
- *                      Query Asynchronous Event.
- *                      Defined two new bits in the SlotStatus field of the SCSI
- *                      Enclosure Processor Request and Reply.
- *  10-28-09  02.00.08  Added defines for decoding the ResponseInfo bytes for
- *                      both SCSI IO Error Reply and SCSI Task Management Reply.
- *                      Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
- *                      Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
- *  02-10-10  02.00.09  Removed unused structure that had "#if 0" around it.
- *  05-12-10  02.00.10  Added optional vendor-unique region to SCSI IO Request.
- *  11-10-10  02.00.11  Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
- *  02-06-12  02.00.13  Added alternate defines for Task Priority / Command
- *                      Priority to match SAM-4.
- *  07-10-12  02.00.14  Added MPI2_SCSIIO_CONTROL_SHIFT_DATADIRECTION.
- *  04-09-13  02.00.15  Added SCSIStatusQualifier field to MPI2_SCSI_IO_REPLY,
- *                     replacing the Reserved4 field.

- *  Date      Version   Description
- *  --------  --------  ------------------------------------------------------
- *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
- *  12-18-07  02.00.01  Added Diagnostic Buffer Post and Diagnostic Release
- *                      structures and defines.
- *  02-29-08  02.00.02  Modified various names to make them 32-character unique.
- *  05-06-09  02.00.03  Added ISTWI Read Write Tool and Diagnostic CLI Tool.
- *  07-30-09  02.00.04  Added ExtendedType field to DiagnosticBufferPost request
- *                      and reply messages.
- *                      Added MPI2_DIAG_BUF_TYPE_EXTENDED.
- *                      Incremented MPI2_DIAG_BUF_TYPE_COUNT.
- *  05-12-10  02.00.05  Added Diagnostic Data Upload tool.
- *  08-11-10  02.00.06  Added defines that were missing for Diagnostic Buffer
- *                      Post Request.
- *  05-25-11  02.00.07  Added Flags field and related defines to
