While doing board reset testing I was able to put the system in
an infinite request/response loop between the scsi layer and
mptscsih_qcmd() by aborting the reset. This patch installs
a "SETUP RESET" handler which calls fc_remote_port_delete()
for all registered rports. This blocks the target which
prevents the loop. Additionally, should the reset fail to
complete, the transport will now terminate i/o to the target.

The fibre channel firmware provides a timer which is similar in purpose
to the fibre channel transport's device loss timer. The effect of this
timer is to extend the total time that a target will be missing beyond
the value associated with the transport's timer. This patch changes
the firmware timer to a default of one second which significantly reduces
the lag between when a target goes missing and the notification of the
fibre channel transport.

mptbase.h
bump version number to 3.03.09
remove unneeded flags
define workq and remove old fc specific locks
mptbase.c
initialize new lock and don't initialize two removed locks
mptscsih.c
when firmware reports target is no longer there, return
DID_REQUEUE for fc hosts so that i/o doesn't get killed until
the transport has an opportunity to manage the loss via its
dev loss timer
when the "eh_abort" routine is called, check to see if the
driver has the command or not before looking to see if a reset
is pending. James Smart and I talked about this and believe
that the API for this routine is: if driver doesn't have
command, return SUCCESS. This change helps prevent a target
from being taken offline. SUCCESS is returned because it's
likely that the command completed after error recovery timed
it out but before it could be aborted.
provide a routine to queue work to newly created workq, and
use it.
remove "ioc" from mptscsih_abort() it was only used one time.
the other references were via hd->ioc, so I just moved it....
net change in references to ioc via hd->ioc is zero
move hd->resetPending test and hd->timeouts increment to after
the test for whether the command to be aborted remains known
to the driver
Make certain that the workq exists before queuing work to it.
mptfc.c
no longer need to lock rport data structures as I was able to
single thread the code! I fixed up the debug code to
eliminate compilation messages due to type mismatch in the
printk. Got rid of some no longer needed rport flags.
Initialize and destroy the workq used for the rescan work.
simplify the logic regarding the increment of
fc_rescan_work_count. use post increment and test for zero
vs. pre increment and test for one; eliminate work_count
variable: queue_work can be called with the work_lock held as
it doesn't sleep

This adds support for hot adding and removing
expanders, and its associated attached devices.
When there is a change in topology,
the fusion firmware sends the
MPI_EVENT_SAS_DISCOVERY event to the driver.
The driver will read firmware config pages
to determine what changes took place, and refresh
drivers view of the world stored in ioc->sas_topology.
Here is the details of the action the driver does:
(1) Expander Added : The mptsas_discovery_work
workqueue is called. Config pages read, and
ioc->sas_topology is refreshed. The sas_phy_add()
is called for each phy of the expander. The
expanders attached devices are added via
sas_rphy_add(). Added end devices are handled within
the MPT_ADD_DEVICE logic in mptsas_hotplug_work
workqueue.
(2) Expander Delete : The sas_rphy_delete() will be
called for the top most compenent of the parent that the
expander is attached to. The sas_rphy_delete call
will delete all the children phys, rphys, and end devices.
This is handled from mptsas_discovery_work workqueue.

It makes no sense in keeping the target_id and bus_id
in the VirtDevice structure, when it can be obtained
from the VirtTarget structure.
In addition, this patch fix's couple compilation bugs
in mptfc.c when MPT_DEBUG_FC is enabled. This

This is the first half of a patch to add the generic domain validation
to mptspi. It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.
What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.
Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.

Adds hotplug support for SAS end devices. Unfortunately the fusion
firmware doesn't generate similar events for expanders addition/removal
so we can't support them yet. Eric has an idea about a clever scheme to
find out about expander changes so that'll be added later on.

This utilizes the hostdata area that is hung off of scsi_target and
scsi_device for saving unique firmware mapping. This will be required
for supporting new Fibre and SPI transport support.
This also fixs problems in error handling error code for SAS
controllers, in which the incorrect mapping was passed to the
firmware.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

Summary of Changes:
* splitting mpt_interrupt per Christophs suggestion
about a month ago
* rename ScsiCfgData to SpiCfgData structure,
then move all the raid related info into
new structure called RaidCfgData. This is
done because SAS supports RAID, as well as SPI,
so the raid stuff should be seperate.
* incorrect timeout calculation for cntdn
inside WaitForDoorbellAck and WaitForDoortbellInt
* add support for interpreting SAS Log Info
* Increase Event Log Size from 0xA to 0x32
* Fix bug in mptsas/mptfc/mptspi - when controller
has Initiator Mode Disabled, and only running in
TargetMode, the mptctl would panic when loading.
The fix is to return 0, instead of -ENODEV, in
SCSI LLD respective probe routines
* Fix bug in mptlan.c - driver will panic if
there is host reset, due to dev being set to
zero in mpt_lan_ioc_reset
* Fix's for SPI - Echo Buffer
* Several fix's in mptscsih_io_done - FCP Response
info, RESIDUAL_MISMATCH, Data Underrun, etc.
* Cleanup Error Handling - EH handlers,
mptscsih_flush_cmds, and zeroing out ScsiLookup
from mptscsih_qcmd
* Cleanup asyn event handling from
mptscsih -> mptscsih_event_process. Also
added support for SAS Persistent Table Full,
an asyn event

- various bits for SAS support from the LSI driver.
- use the device private data for the fusion target private data.
this should be using the midlayer target data framework, but we
can't move over to that until fusion has been switched to the
generic DV code
- use target ID and channel from the fusion target private data,
because those in scsi_device will be different for mptsas

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
