Pull final round of SCSI updates from James Bottomley:
 "This is primarily another round of driver updates (bnx2fc, qla2xxx,
  qla4xxx) including the target mode driver for qla2xxx.  We've also got
  a couple of regression fixes (async scanning, broken this merge window
  and a fix to a long standing break in the scsi_wait_scan module)."

    PM/Hibernate: Wait for SCSI devices scan to complete during resume

Broke the scsi_wait_scan module in 2.6.30.  Apparently debian still uses it so
fix it and backport to stable before removing it in 3.6.

The breakage is caused because the function template in
include/scsi/scsi_scan.h is defined to be a nop unless SCSI is built in.
That means that in the modular case (which is every distro), the
scsi_wait_scan module does a simple async_synchronize_full() instead of
waiting for scans.

Commit a7a20d1 "[SCSI] sd: limit the scope of the async probe domain"
moved sd probe work out of reach of wait_for_device_probe().  Allow it
to be synced via scsi_complete_async_scans().

This patch should go into 3.5 fixes. The bug was added in the
patches for the 3.5 feature window.

As you can see from the patch I made a mistake. During
development I switched from passing a struct to the size of
the struct, but left the sizeof. This results in us allocating
4 bytes (sizeof(int)) but then calling pci_free_consistent
with the size of the struct.

change_queue_depth will adjust device queuedepth upon receiving
"SAM_STAT_TASK_SET_FULL" scsi status from the target.
Also added ql4xqfulltracking command line param to enable or disable
queuefull tracking. One can disabling queuefull tracking to ensure
user set scsi device queuedepth is not altered.

Allow ddb state to change to DDB_DS_NO_CONNECTION_ACTIVE or
DDB_DS_SESSION_FAILED before issuing clear ddb mailbox cmd,
because clear ddb mailbox cmd fails if the ddb state is not
equal to DDB_DS_NO_CONNECTION_ACTIVE or DDB_DS_SESSION_FAILED.

Update the session and connection parameter before sending
connection logged in event to iscsiadm because in some
scenario logout may come in just after we send the logged
in event to user, which free up session, connection and ddb,
but DPC is still updating session and connect parameter
which can lead to panic.

Check for Firmware Hang (AF_FW_RECOVERY) after mailbox command
has gained access to ensure that the mailbox command does not
wait un-necessarily during a firmware recovery and prevent
premature mailbox timeout which will lead to back to back reset's.
