The SCSI midlayer already prints more detail about completions,
and has logging level options to filter them if not wanted.
These just slow down the system if a lot of errors occur,
stressing error handling even more.

Increase the request size for ioaccel2 path.
The error, if any, returned by hpsa_allocate_ioaccel2_sg_chain_blocks
to hpsa_alloc_ioaccel2_cmd_and_bft should be returned upstream rather
than assumed to be -ENOMEM.
This differs slightly from hpsa_alloc_ioaccel1_cmd_and_bft,
which does not call another hpsa_allocate function and only
has -ENOMEM to return from some kmalloc calls.

Factor out hpsa_cmd_init from cmd_alloc(). We also need
this for resubmitting commands down the default RAID path
when they have returned from the ioaccel paths with errors.
In particular, reinitialize the cmd_type and busaddr fields as these
will not be correct for submitting down the RAID stack path
after ioaccel command completion.
This saves time when submitting commands.

In hba mode, we could get sense data in descriptor format so
we need to handle that.
It's possible for CommandStatus to have value 0x0D
"TMF Function Status", which we should handle. We will get
this from a P1224 when aborting a non-existent tag, for
example. The "ScsiStatus" field of the errinfo field
will contain the TMF function status value.

Do not send aborts to logical devices that do not support aborts
Instead of relying on what the Smart Array claims for supporting logical
drives, simply try an abort and see how it responds at device discovery
time. This way devices that do support aborts (e.g. MSA2000) can work
and we do not waste time trying to send aborts to logical drives that do
not support them (important for high IOPS devices.)
While rescanning devices only test whether devices support aborts
the first time we encounter a device rather than every time.
Some Smart Arrays required aborts to be sent with tags in
the wrong endian byte order. To avoid having to know about
this, we would send two aborts with tags with each endian order.
On high IOPS devices, this turns out to be not such a hot idea.
So we now have a list of the devices that got the tag backwards,
and we only send it one way.
If all available commands are outstanding and the abort handler
is invoked, the abort handler may not be able to allocate a command
and may busy-wait excessivly. Reserve a small number of commands
for the abort handler and limit the number of concurrent abort
requests to the number of reserved commands.

Allow driver initiated commands to have a timeout. It does not
yet try to do anything with timeouts on such commands.
We are sending a reset in order to get rid of a command we want to abort.
If we make it return on the same reply queue as the command we want to abort,
the completion of the aborted command will not race with the completion of
the reset command.
Rename hpsa_scsi_do_simple_cmd_core() to hpsa_scsi_do_simple_cmd(), since
this function is the interface for issuing commands to the controller and
not the "core" of that implementation. Add a parameter to it which allows
the caller to specify the reply queue to be used. Modify existing callers
to specify the default reply queue.
Rename __hpsa_scsi_do_simple_cmd_core() to hpsa_scsi_do_simple_cmd_core(),
since this routine is the "core" implementation of the "do simple command"
function and there is no longer any other function with a similar name.
Modify the existing callers of this routine (other than
hpsa_scsi_do_simple_cmd()) to instead call hpsa_scsi_do_simple_cmd(), since
it will now accept the reply_queue paramenter, and it provides a controller
lock-up check. (Also, tweak two related message strings to make them
distinct from each other.)
Submitting a command to a locked up controller always results in a timeout,
so check for controller lock-up before submitting.
This is to enable fixing a race between command completions and
abort completions on different reply queues in a subsequent patch.
We want to be able to specify which reply queue an abort completion
should occur on so that it cannot race the completion of the command
it is trying to abort.
The following race was possible in theory:
1. Abort command is sent to hardware.
2. Command to be aborted simultaneously completes on another
reply queue.
3. Hardware receives abort command, decides command has already
completed and indicates this to the driver via another different
reply queue.
4. driver processes abort completion finds that the hardware does not know
about the command, concludes that therefore the command cannot complete,
returns SUCCESS indicating to the mid-layer that the scsi_cmnd may be
re-used.
5. Command from step 2 is processed and completed back to scsi mid
layer (after we already promised that would never happen.)
Fix by forcing aborts to complete on the same reply queue as the command
they are aborting.
Piggybacking device rescanning functionality onto the lockup
detection thread is not a good idea because if the controller
locks up during device rescanning, then the thread could get
stuck, then the lockup isn't detected. Use separate work
queues for device rescanning and lockup detection.
Detect controller lockup in abort handler.
After a lockup is detected, return DO_NO_CONNECT which results in immediate
termination of commands rather than DID_ERR which results in retries.
Modify detect_controller_lockup() to return the result, to remove the need for
a separate check.

We had a mix of formats used for specifying controller, bus, target,

change to the format used by the scsi midlayer and upper layer (2:3:0:0)

Also add this information:

- vendor ID
- RAID level
- SSD Smath Path capable and enabled
- exposure level (sg-only)

Cache the ioaccel handle so that when we need to abort commands sent
down the ioaccel2 path, we can look up the LUN ID in h->dev[] instead of
having to do I/O to the controller.
Add a field to elements in h->dev[] to keep track of how the device is exposed
to the SCSI mid layer: Not at all, without an upper level driver
(no_uld_attach) or normally exposed.
Since masked physical devices are now present in h->dev[] array
it would be perfectly possible to do
echo scsi add-single-device 2 2 0 0 > /proc/scsi/scsi
and bring them online. This was previously not allowed for masked
physical devices.
Ensure that the mapping of physical disks to logical drives gets updated in a
consistent way when a RAID migration occurs and is not touched until updates
to it are complete.
now instead of doing CISS_REPORT_PHYSICAL to get the LUNID for
the physical disk in hpsa_get_pdisk_of_ioaccel2(), just get
it out of h->dev[] where we already have it cached.
