For shared SAS configurations, hosts need to poll Smart Arrays
periodically in order to be able to detect configuration changes
such as logical drives being added or removed from remote hosts.
A register on the controller indicates when such events have
occurred, and the driver polls the register via a workqueue
and kicks off a rescan of devices if such an event is detected.
Additionally, changes to logical drive raid offload eligibility
are autodetected in this way.

This enables sending i/o's destined for RAID logical drives
which can be serviced by a single physical disk down a different,
faster i/o path directly to physical drives for certain logical

For "mode 1" io accelerated commands, the command tag is in

When commands sent down the "fast path" fail, they must be re-tried down the
normal RAID path. We do this by kicking i/o's back to the scsi mid layer with
a DID_SOFT_ERROR status, which causes them to be retried. This won't work for
SG_IO's and other non REQ_TYPE_FS i/o's which could get kicked all the way back
to the application, which may have no idea that the command needs resubmitting
and likely no way to resubmit it in such a way the that driver can recognize it
as a resubmit and send it down the normal RAID path. So we just always send
non REQ_TYPE_FS i/o's down the normal RAID path, never down the "fast path".

Commit 254f796b9f updated
the driver to use 16 MSI-X vectors, despite the fact that
older controllers would provide only 4.
This was causing MSI-X registration to drop down to INTx
mode. But as the controller support performant mode, the
initialisation will become confused and cause the machine
to stall during boot.
This patch fixes up the MSI-X registration to re-issue
the pci_enable_msix() call with the correct number of
MSI-X vectors. With that the hpsa driver continues to
works on older controllers like the P200.

If a fifo full condition is encountered, i/o requests will stack
up in the h->reqQ queue. The only thing which empties this queue
is start_io, which only gets called when new i/o requests come in.
If none are forthcoming, i/o in h->reqQ will be stalled.
To fix this, whenever fifo full condition is encountered, this
is recorded, and the interrupt handler examines this to see
if a fifo full condition was recently encountered when a
command completes and will call start_io to prevent i/o's in
h->reqQ from getting stuck.
I've only ever seen this problem occur when running specialized
test programs that pound on the the CCISS_PASSTHRU ioctl.

Cap CCISS_BIG_PASSTHRU as well. If an attempt is made
to exceed this, ioctl() will return -1 with errno == EAGAIN.
This is to prevent a userland program from exhausting all of
pci_alloc_consistent memory. I've only seen this problem when
running a special test program designed to provoke it. 20
concurrent commands via the passthru ioctls (not counting SG_IO)
should be more than enough.

The hardware guys tell us that after initiating a software
reset via the doorbell register we need to wait 5 seconds before
attempting to talk to the board *at all*. This means that we
cannot watch the board to verify it transitions from "ready" to
to "not ready" then back "ready", since this transition will
most likely happen during those 5 seconds (though we can still
verify the reset happens by watching the "driver version" field
get cleared.)

A return value of 1 is interpreted as an error. See pci_driver.
in local_pci_probe(). If you're wondering how this ever could
have worked, it's because it used to be the case that only return
values less than zero were interpreted as failure. But even in
the current kernel if the driver registers its various entry
points with the kernel, and then returns a value which is
interpreted as failure, those registrations aren't undone, so
the driver still mostly works. However, the driver's remove
function wouldn't be called on rmmod, and pci power management
functions wouldn't work. In the case of Smart Array, since it
has a battery backed cache (or else no cache) even if the driver
is not shut down properly as long as there is no outstanding
i/o, nothing too bad happens, which is why it took so long to
notice.
Requesting backport to stable because the change to pci-driver.c
which requires driver probe functions to return 0 occurred between
2.6.35 and 2.6.36 (the pci power management breakage) and again
between 3.7 and 3.8 (pci_dev->driver getting set to NULL in
local_pci_probe() preventing driver remove function from being
called on rmmod.)

We inadvertantly discarded the scsi status for aborted commands.
For some commands (e.g. reads from tape drives) these can't be retried,
and if we discarded the scsi status, the scsi mid layer couldn't notice
anything was wrong and the error was not reported.

Some host adapters do not pass commands through to the target disk
directly. Instead they provide an emulated target which may or may not
accurately report its capabilities. In some cases the physical device
characteristics are reported even when the host adapter is processing
commands on the device's behalf. This can lead to adapter firmware hangs
or excessive I/O errors.
This patch disables WRITE SAME for devices connected to host adapters
that provide an emulated target. Driver writers can disable WRITE SAME
by setting the no_write_same flag in the host adapter template.

-------------------
This is caused by
enqueue_cmd_and_start_io()->
set_performant_mode()->
smp_processor_id()
Which if you have debugging enabled calls debug_processor_id() and triggers the warning.
The code here is
c->Header.ReplyQueue = smp_processor_id() % h->nreply_queues;
Since it is not critical that the code complete on the same processor,
but the cpu is a hint used in generating the ReplyQueue and will still work if
the cpu migrates or is preempted, it is safe to use the raw_smp_processor_id()
to surpress the false positve warning.

This is a large set of updates, mostly for drivers (qla2xxx [including support
for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa, be2iscsi, isci,
lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas). There's also a rework for tape
adding virtually unlimited numbers of tape drives plus a set of dif fixes for
sd and a fix for a live lock on hot remove of SCSI devices.
This round includes a signed tag pull of isci-for-3.6
