db7051b298 [SCSI] mpt fusion: Added support for Broadcast primitives Event handling
Firmware is able to handle Broadcast primitives, but upstream driver does not
have support for broadcast primitive handling. Now this patch is mainly to
support broadcast primitives.

Resending patch considering Grants G's code review.

Main goal to submit this patch is code cleaup.
1. Better driver debug prints and code indentation.
2. fault_reset_work_lock is not used anywhere. driver is using taskmgmt_lock
instead of fault_reset_work_lock.
3. setting pci_set_drvdata properly.
4. Ingore config request when IOC is in reset state.( ioc_reset_in_progress
is set).
5. Init/clear managment frame proprely.(INITIALIZE_MGMT_STATUS and
CLEAR_MGMT_STATUS)

14d0f0b063 [SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory region
The reason for this change is there is a data corruption when four different
physical memory regions in the 36GB to 37GB region are
accessed. This is only affecting 1078.

The solution is we need to use different addressing when filling in
the scatter gather table for the effected memory regions.  So instead
of snooping on all four different memory holes, we treat any physical
addresses in the 36GB address with the same algorithm.

The fix is explained below
1) Ensure that the message frames are NOT located in the trouble
region. There is no remapping available for message frames, they must
be allocated outside the problem region.
2) Ensure that Sense buffers are NOT in the trouble region. There is
no remapping available.
3) Walk through the SGE entries and if any are inside the trouble region
   then they need to be remapped as discussed below.
	1) Set the Local Address bit in the SGE Flags field.
  	MPI_SGE_FLAGS_LOCAL_ADDRESS
  	2) Ensure we are using 64-bit SGEs
  	3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer
	location is Host Memory.

7748369f49 [SCSI] mptsas: do not use ioc->handle to locate hba portinfo structure
While performing hardware raid reset testing via the raid's client, I
noticed that sometimes, following the reset, that there would be more
raid targets in the lsscsi output than there actually were raid
targets.  I tracked this down to the following issue.

Fusion cannot always find the mptsas_portinfo structure for the hba
because it uses the handle stored in ioc->handle to locate it.  The
problem is that the firmware can change the handle associated with the
hba when h/w raid is reset (via the raid client).  When this happens,
the driver will allocate another mptsas_portinfo structure and link it
into the chain of said structures.  This ultimately causes confusion
within the driver resulting in targets not being removed when they
should be.

Eric Moore pointed out that the hba's portinfo structure is always the
first structure on the sas_topology list.  This patch modifies
mptsas.c to access the hba's portinfo structure by taking the first
structure on said list.

35508e46aa [SCSI] mptfc: stall eh handlers if resetting while rport blocked
Thanks to James Smart for the inspiration.

Stall error handler if attempting recovery while an rport is blocked.
This avoids device offline scenarios due to errors in the error handler.
Also verify that VirtDevice is available before issuing scsi command.
VirtDevice is removed when fc transport removes a target.

See James Smart's patch of 08/17/2006 for greater detail.
