[SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.
This fix:
- Disables app tag peeking; correct tag check will be added when the
SCSI API is available.
- Always derive ref_tag from scsi_get_lba()
- Removes incorrect swap of FCP_LUN in FCP_CMND
- Moves app-tag error check before ref-tag check. The reason being,
currently there is no interface in SCSI to retrieve the app-tag
for protection I/Os, so driver puts zero for app-tag in the
firmware interface, but requests not to validate it, but when a
ref-tag error is detected by firmware, it would put
expected/actual tags for all the protection tags (guard/app/ref).
As driver checks for app tag error first, a ref-tag error is
incorrectly flagged as app-tag error.
- Convert HBA specific checks to capability based.

[SCSI] qla2xxx: Use GFF_ID to check FCP-SCSI FC4 type before logging into Nx_Ports
The default method that qla2xxx uses is the GID_PT nameserver command to
get a list of Nx_Ports. This patch adds a GFF_ID call for each port
returned by GID_PT to get the FC4 type. If the FC4 type is not FCP SCSI
then the qla2xxx driver will not record that port in it's port database.
For switches that do not support the GFF_ID command, the behavior will be
for qla2xxx to store that port anyways.

[SCSI] qla2xxx: Handle outstanding mbx cmds on hung f/w scenarios.
Outstanding mailbox commands, have no way to recover on f/w hung, and we
timeout on waiting for mbx response. This in turn affects the recovery process
as follows:
- We might already be in dpc while waiting for mbx to complete, so recovery for
that pci function will never get invoked. Reset Timeout (10 sec) is far less
than mbx timeout (30 sec).
- Other mbx cmds will get stuck due to serial mbx access.
Solution is to identify fw-hung scenario and handle outstanding mbx commands to
have an early-exit instead of waiting for response.
Other mbx commands waiting for access will also do an early-exit if fw-hung is
still applicable.

[SCSI] qla2xxx: Add char device to increase driver use count
The driver should not be unloaded if any application is using it.
To disallow driver unload, driver use count must be incremented.

[SCSI] qla2xxx: add support for multi-queue adapter
Following changes have been made.
1. qla_hw_data structure holds an array for request queue pointers,
and an array for response queue pointers.
2. The base request and response queues are created by default.
3. Additional request and response queues are created at the time of vport
creation. If queue resources are exhausted during vport creation, newly
created vports use the default queue.
4. Requests are sent to the request queue that the vport was assigned
in the beginning.
5. Responses are completed on the response queue with which the request queue
is associated with.

3. Request and response IO specific data strucures are created.
4. The global list of fcports for the hba is not maintained anymore,
instead a fcport list is construted on per scsi_qla_host.

[SCSI] qla2xxx: Explicitly tear-down vports during PCI remove_one().
During internal testing, we've seen issues (hangs) with the
'deferred' vport tear-down-processing typically accompanied with
the fc_remove_host() call. This is due to the current
implementation's back-end vport handling being performed by the
physical-HA's DPC thread where premature shutdown could lead to
latent vport requests without a processor.
This should also address a problem reported by Gal Rosen
(http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the
driver would attempt to awaken a previously torn-down DPC thread
from interrupt context by implicitly calling wake_up_process()
rather than the driver's qla2xxx_wake_dpc() helper. Rather, than
reshuffle the remove_one() device-removal code, during unload,
depend on the driver's timer to wake-up the DPC process, by
limiting wake-ups based on an 'unloading' flag.

[SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support.
FCE support enables the firmware to record FC extended link
services and basic link services frames which have been
transmitted and received by the ISP. This allows for a limited
view of the FC traffic through the ISP without using a FC
analyzer. This can be useful in situations where a physical
connection to the FC bus is not possible.
The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:
<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
where a read of the 'fce' file will provide a snapshot of the
firmware's FCE buffer; and finally, the FCE buffer will be
extracted during a firmware-dump scenario.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

[SCSI] qla2xxx: Add iIDMA support.
iIDMA (Intelligent Interleaved Direct Memory Access) allows for
the HBA hardware to send FC frames at the rate at which they can
be received by a target device. By taking advantage of the
higher link rate, the HBA can maximize bandwidth utilization in a
heterogeneous multi-speed SAN.
Within a fabric topology, port speed detection is done via a Name
Server command (GFPN_ID) followed by a Fabric Management command
(GPSC). In an FCAL/N2N topology, port speed is based on the HBA
link-rate.

[SCSI] qla2xxx: Correct synchronization issues during rport addition/deletion.
The driver can typically detect port-loss during an
interrupt context (i.e. via interrogation of a status IOCB's
completion status [CS_PORT_LOGGED_OUT]. Due to the calling
requirements of the fc_rport APIs, the driver would defer
removal of the device to the default workqueue. If the
work-item was preceded by an event which caused the port to
obtain visibility (relogin successful, target re-logged into
the topology), deferred removal could inadvertently drop the
rport. The code also no longer defers removal via the
default workqueue, instead opting for use of the driver's
own DPC thread.

[SCSI] qla2xxx: Correct mis-handling of AENs.
A regression in a recent change
33135aa2a568ec1a30e734f18e5315e10516e4f3 caused the driver
to mistakenly drop handling of AENs. Due to the incorrect
handling, ports would not reappear after RSCNs and LIPs.
Drops unused/incorrect compound #define from qla_def.h.

[SCSI] update fc_transport for removal of block/unblock functions
We recently went back to implement a board reset. When we perform the
reset, we wanted to tear down the internal data structures and rebuild
them. Unfortunately, when it came to the rport structure, things were
odd. If we deleted them, the scsi targets and sdevs would be
torn down. Not a good thing for a temporary reset. We could block the
rports, but we either maintain the internal structures to keep the
rport reference (perhaps even replicating what's in the transport),
or we have to fatten the fc transport with new search routines to find
the rport (and deal with a case of a dangling rport that the driver
forgets).
It dawned on me that we had actually reached this state incorrectly.
When the fc transport first started, we did the block/unblock first, then
added the rport interface. The purpose of block/unblock is to hide the
temporary disappearance of the rport (e.g. being deleted, then readded).
Why are we making the driver do the block/unblock ? We should be making
the transport have only an rport add/delete, and the let the transport
handle the block/unblock.
So... This patch removes the existing fc_remote_port_block/unblock
functions. It moves the block/unblock functionality into the
fc_remote_port_add/delete functions. Updates for the lpfc driver are
included. Qlogic driver updates are also enclosed, thanks to the
contributions of Andrew Vasquez. [Note: the qla2xxx changes are
relative to the scsi-misc-2.6 tree as of this morning - which does
not include the recent patches sent by Andrew]. The zfcp driver does
not use the block/unblock functions.
One last comment: The resulting behavior feels very clean. The LLDD is
concerned only with add/delete, which corresponds to the physical
disappearance. However, the fact that the scsi target and sdevs are
not immediately torn down after the LLDD calls delete causes an
interesting scenario... the midlayer can call the xxx_slave_alloc and
xxx_queuecommand functions with a sdev that is at the location the
rport used to be. The driver must validate the device exists when it
first enters these functions. In thinking about it, this has always
been the case for the LLDD and these routines. The existing drivers
already check for existence. However, this highlights that simple
validation via data structure dereferencing needs to be watched.
To deal with this, a new transport function, fc_remote_port_chkready()
was created that LLDDs should call when they first enter these two
routines. It validates the rport state, and returns a scsi result
which could be returned. In addition to solving the above, it also
creates consistent behavior from the LLDD's when the block and deletes
are occuring.

[SCSI] qla2xxx: Add support to dynamically enable/disable ZIO.
ISP23xx and ISP24xx chips have support for an adaptive
method of posting SCSI command completions for multiple SCSI
commands during a single system interrupt.
SCSI commands are placed on the system response queue
without interrupting the host until 1) a delay timer
expires; or 2) a SCSI command completes with an error.
As long as the host software (qla2xxx) services the response
queue for completions (this polling is done during
queuecommand()) within the 'delay timer' period, the
firmware will not generate system interrupt.

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!
