The problem here is that if the ioc faults too early in the bring up
sequence (as it usually does for an irq routing problem), ioc_reset gets
called before the scsi host is even allocated. This causes an oops when
it later schedules a renegotiation. Fix this by checking ioc->sh before
trying to renegotiate.

Following a hard reset of a SAS raid, one of the raid targets is occasionally
missing. I tracked this down to a pretty obscure little bug.
The LSI fusion drivers for SAS and Fibre Channel both use their respective
transport layers. Those transport layers increment the target number
assigned to new targets.
The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host
structure to avoid scanning the scsi host adapter. Both fusion drivers set
"this_id" from a value returned in a firmware PortFacts response. For my
particular test case (SAS) the firmware id assigned to the initiator was
173. After enough raid resets to cause the raid targets to go and come a
sufficient number of times, the id assigned by the transport to a raid
target would match the id assigned by the host adapter to the "this_id"
field, resulting in that target not being scanned.
Fix by not assigning this_id and not checking it in slave_configure.

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.

NB = number of blocks. This represents the number of blocks to
transfer. The block size is based on the message frame size provided
in the ioc_facts. A value of zero indicates the entire message frame
should be copied. This is two bit value. So by setting this to
non-zero vaule, you increase performance by reducing amount of data
needing to be dma'd. The value that is stored in ioc->ReqeustNB is
sometimes a non-zero vaule, which creates a bug in mptlan, where not
the entire message frame is getting transfer to firware, resulting in
corruption. This fix sets the default to zero, thus entire message

There are two returns that may leak the storage allocated for 'ioc'

A simple fix would be to simply add two kfree() calls before the return
statements, but a better fix (that this patch implements) is to reorder the
code so that if we hit the first return condition we don't have to do the
allocation at all and then just add a kfree() call for the second case.

This patch fixes access to memory that has not been allocated:
i2o_msg_get_wait() can returns errors different from I2O_QUEUE_EMPTY. But the
result is checked only against this code. If it is not I2O_QUEUE_EMPTY then
we dereference the error code as the pointer later.

This patch fixes a number of issues in i2o_cfg_passthru{,32}:
- i2o_msg_get_wait() return vaile is not checked;
- i2o_message memory leaks on error paths;
- infinite loop to sg_list_cleanup in passthru32
It's important issue because of i2o_cfg_passthru is used by raidutils for
monitorig controllers state, and in case of memory shortage it leads to the
node crash or disk IO stall.

If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.
