Eric Moore 635374e7eb [SCSI] mpt2sas v00.100.11.15 
* This is new scsi lld device driver from LSI supporting the SAS 2.0
  standard. I have split patchs by filename.

* Here is list of new 6gb host controllers:

  LSI SAS2004
  LSI SAS2008
  LSI SAS2108
  LSI SAS2116

* Here are the changes in the 4th posting of this patch set:

(1) fix compile errors when SCSI_MPT2SAS_LOGGING is not enabled
(2) add mpt2sas to the SCSI Mid Layer Makefile
(3) append mpt2sas_ to the naming of all non-static functions
(4) fix oops for SMP_PASSTHRU
(5) doorbell algorithm imported changes from windows driver

* Here are the changes in the 3rd posting of this patch set:

(1) add readl following writel from the function that disables interrupts
(2) replace 0xFFFFFFFFFFFFFFFFULL with ~0ULL
(3) when calling pci_enable_msix, only pass one msix entry (instead of 15).
(4) remove the "current HW implementation uses..... " comment in the sources
(5) merged bug fix for SIGIO/POLLIN notifcation; reported by the storlib team.

* Here are the changes in the 2nd posting of this patch set:

(1) use little endian types in the mpi headers
(2) merged in bug fix's from inhouse drivers.

* Date Version Description
* -------- -------- ------------------------------------------------------
* 04-30-07 02.00.00 Corresponds to Fusion-MPT MPI Specification Rev A.
* 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 becasue they are
* common to many structures.
