Mike Miller 7c03b87048 [SCSI] hpsa: fix redefinition of PCI_DEVICE_ID_CISSF
PCI_DEVICE_ID_CISSF is defined as 323b in pci_ids.h but redefined as 3fff in
hpsa.c. The ID of 3fff will _never_ ship as a standalone controller. It is
intended only as part a complete storage solution. As such, this patch
removes the redefinition and the StorageWorks P1210m from the product table.

It also removes a duplicate line for the "unknown" controller support.

James Bottomley 459dbf72e4 [SCSI] Eliminate error handler overload of the SCSI serial number
The error handler is using the test cmd->serial_number == 0 in the
abort routines to signal that the command to be aborted has already
completed normally.  This design was to close a race window in the
original error handler where a command could go through the normal
completion routines after it timed out but before error handling was
started.

Mike Anderson pointed out that when we converted our timeout and
softirq completions, we picked up atomicity here because the block
layer now mediates this with the REQ_ATOM_COMPLETE flag and guarantees
that *either* the command times out or our done routine is called, but
ensures we can't get both occurring.  That makes the serial number
zero check redundant and it can be removed.

Jeff Garzik f281233d3e SCSI host lock push-down
Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.

The patch below presents a simple SCSI host lock push-down as an
equivalent transformation.  No locking or other behavior should change
with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,
	struct Scsi_Host *
and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.

REQ_HARDBARRIER is dead now, so remove the leftovers.  What's left
at this point is:

 - various checks inside the block layer.
 - sanity checks in bio based drivers.
 - now unused bio_empty_barrier helper.
 - Xen blockfront use of BLKIF_OP_WRITE_BARRIER - it's dead for a while,
   but Xen really needs to sort out it's barrier situaton.
 - setting of ordered tags in uas - dead code copied from old scsi
   drivers.
 - scsi different retry for barriers - it's dead and should have been
   removed when flushes were converted to FS requests.
 - blktrace handling of barriers - removed.  Someone who knows blktrace
   better should add support for REQ_FLUSH and REQ_FUA, though.

Boaz Harrosh e96e72c45a [SCSI] libosd: Support for scatter gather write/read commands
This patch adds the Scatter-Gather (sg) API to libosd.
Scatter-gather enables a write/read of multiple none-contiguous
areas of an object, in a single call. The extents may overlap
and/or be in any order.

The Scatter-Gather list is sent to the target in what is called
a "cdb continuation segment". This is yet another possible segment
in the osd-out-buffer. It is unlike all other segments in that it
sits before the actual "data" segment (which until now was always
first), and that it is signed by itself and not part of the data
buffer. This is because the cdb-continuation-segment is considered
a spill-over of the CDB data, and is therefor signed under
OSD_SEC_CAPKEY and higher.

TODO: A new osd_finalize_request_ex version should be supplied so
the @caps received on the network also contains a size parameter
and can be spilled over into the "cdb continuation segment".

Thanks to John Chandy <john.chandy@uconn.edu> for the original
code, and investigations. And the implementation of SG support
in the osd-target.

depending on the state the driver's FIP engine is in.

Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful

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.

Chad Dupuis ff454b01b4 [SCSI] qla2xxx: Group CS_RESET return status with other link level event 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.

Chad Dupuis 4d97cc5342 [SCSI] qla2xxx: Change del_timer_sync() to del_timer() in qla2x00_ctx_sp_free().
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.

Add the module parameter ql2xgffidenable to disable/enable the use of the
GFF_ID name server command to prevent non FCP SCSI devices from being added to
the driver's internal fc_port database.
