This patch fixes an issue which causes the firmware to fail with a
'PRLI failed' status code (iop1 = 405). This status triggers the
driver to fall into an incorrect code-path which does not attempt
a login retry.

This patch fixes a regression introduced by commit
083a469db4ecf3b286a96b5b722c37fc1affe0be
qla2xxx_eh_wait_on_command() is waiting for an srb to
complete, which will never happen as the routine took
a reference to the srb previously and will only drop it
after this function. So every command abort will fail.

This patch adds a shutdown handler to qla2xxx driver to make sure that all
DMA and firmware activities are stopped, and any associated driver resources
are released. The need for this handler arose when executing kexec in specific
environments caused the data of the 2nd kernel to be corrupted, due to DMA
activities.

statuses.
Currently when we receive a CS_RESET as a response for a SCSI command the
driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer. There
are certain circumstances where this could cause the mid-layer to exhaust all of
its retries if the FC port goes away for a short time. This will result in
commands being prematurly failed. Moving the CS_RESET return code to be
grouped with other link level events will cause the FC transport layer to block
that target's queue thus preventing the premature exhaustion of retries.

Using del_timer_sync() in the qla2x00_ctx_sp_free() function may cause a kernel
panic as it is not interrupt context safe and qla2x00_ctx_sp_free() may be
called from a softirq context. Changing the call from del_timer_sync() to
del_timer() will make the function interrupt context safe.

This patch removes the use of the port down retry counter as a mechanism to
update a fcport state. The internal driver counter is a residual carry-over
from pre-FC-transport aware driver inteaction. The ql2xport_down_retry module
parameter and NVRAM set ha->port_down_retry_count remain in order to seed the
fc-host's default dev-loss-tmo.

IRQs are already disabled here so we don't need to disable them again.
But more importantly, the spin_lock_irqsave() overwrites "flags" and
that breaks things when we want to re-enable the IRQs when we call
spin_unlock_irqrestore(&ha->hardware_lock, flags);

This removes the driver's get_host_def_dev_loss_tmo
callback and just has the driver set the dev loss
using the fc class fc_host_dev_loss_tmo macro like is
done for other fc params.

to indicate this to every FCoE function. The FC/FCoE driver is

Currently the IOs are returned back in slot reset, this
could be late and can cause error handler to invoke.
If error handler invokes, eh_abort fails and escalate to
device/bus/host resets causing issues.
The commands need to be returned back to upper layer in
io_error_detected.

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

The seconds_since_last_heartbeat should be checked for consecutive
heartbeat checks. Currently it could happen that seconds_since_last_heartbeat
gets set to max (2 seconds) for non-consecutive heartbeat checks.

This function was added to encapsulate freeing the memory for all the fcports
associated with a particular vha. Also added a call to qla2x00_free_fcports()
to qla2x00_free_device() to free the memory for all the fcports associated with
a vha during device removal.

Earlier implementation did not take into account the varying
sizes of data buffers returned from structures sts_entry_t and
sts_entry_24xx. Sense-data after the 20th byte could be
incorrect.

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.
