Impact: fix bug
the third param in module_param(,,) is perm instead of default value.
we still need to assign default at first. Also, the default is now
zero not one, so fix the parameter text to reflect that.

A bug in the fusion driver was exposed by the switch to block timeout.
Basically, drivers are supposed to terminate commands once error
handling begins on them. The fusion apparently wasn't doing this.
Under the old timeout regime, completions on terminated commands would
by and large get ignored because of the way command timeouts used to
work. The new block timers are very intolerant to this, though,
becuase the request gets cleaned and freed.

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.
So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

When the firmware is in Fault state it will be identifed only when the next time
the driver access the IOC state.
This patch includes a polling function in the driver which will be executed in
regular interval to check the status of the firmware and if it is in Fault
state, then the firmware will be reset by the driver.

There's a fault on the FC controllers that makes them not respond
correctly to MSI. The SPI controllers are fine, but are likely to be
onboard on older motherboards which don't handle MSI correctly, so
default both these cases to disabled. Enable by setting the module
parameter mpt_msi_enable=1.
For the SAS case, enable MSI by default, but it can be disabled by
setting the module parameter mpt_msi_enable=0.

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.
