f0ad30d3d2 [SCSI] libsas: fix NCQ mixing with non-NCQ
Some cards (like mvsas) have issue troubles if non-NCQ commands are
mixed with NCQ ones.  Fix this by using the libata default NCQ check
routine which waits until all NCQ commands are complete before issuing
a non-NCQ one.  The impact to cards (like aic94xx) which don't need
this logic should be minimal

045d3fe766 [SCSI] sd: Update thin provisioning support
Add support for the Thin Provisioning VPD page and use the TPU and TPWS
bits to switch between UNMAP and WRITE SAME(16) for discards.  If no TP
VPD page is present we fall back to old scheme where the max descriptor
count combined with the max lba count are used trigger UNMAP.

d99e5f488a [SCSI] ibmvfc: Log link up/down events
By default, ibmvfc does not log any async events in order
to avoid flooding the log with them. Improve on this by
logging by default events that are not likely to flood the
log, such as link up/down. Having these events in the log
will improve the ability to debug issues with ibmvfc.

9b90677956 [SCSI] scsi_debug: Convert to use root_device_register() and root_device_unregister()
This patch updates the scsi_debug virtual LLD to use
root_device_register() and root_device_unregister() from
include/linux/device.h instead of device_register() and
device_unregister() respectively within scsi_debug_init() and
scsi_debug_exit() This simply involved converting the static struct
device pseudo_primary into a pointer that is setup by the call to
root_device_register().

This patch also contains the correct IS_ERR() conditional check of
root_device_register() from within scsi_debug_init().

Thanks to Richard Sharpe and Dmitry Torokhov for their help with this
item.

78d16341fa [SCSI] scsi_transport_fc: fix blocked bsg request when fc object deleted
When an rport is "blocked" and a bsg request is received, the bsg request gets
placed on the queue but the queue stalls. If the fc object is then deleted - the
bsg queue never restarts and keeps the reference on the object, and stops the
overall teardown.

This patch restarts the bsg queue on teardown and drains any pending requests,
allowing the teardown to succeed.

6014759c92 [SCSI] scsi_debug: Update thin provisioning support
The previous thin provisioning support was not very user friendly
because it depended on all the relevant options being set on the command
line.

Implement support for the Thin Provisioning VPD page from SBC3 r24 and
add module options for TPU (UNMAP) and TPWS (WRITE SAME (16) with UNMAP
bit).  This allows us to have sane default and to enable thin
provisioning with a simple tpu=1 or tpws=1 on the command line depending
on whether we want UNMAP or WRITE SAME behavior.

e3b3e62467 [SCSI] scsi/block: increase flush/sync timeout
We have been seeing the flush request timeout with a wide
range of hardware from tgt+iser to FC targets from a major vendor.

After discussions about if the value should be configurable and
what the best value should be, this patch just increases the flush/sync
cache timeout to 1 minute. 2 minutes was determined to be too long, and
making it configurable was troublesome for users.

This patch was made over Linus's tree. It is not made over scsi-misc
or scsi-rc-fixes, because Linus's had block layer changes that my
patch was built over.

d80e0d96a3 scsi: 53c700: remove dma_is_consistent usage
This driver is the only user of dma_is_consistent().  We plan to remove this
API.

The driver uses the API in the following way:

BUG_ON(!dma_is_consistent(hostdata->dev, pScript) && L1_CACHE_BYTES < dma_get_cache_alignment());

The above code tries to see if L1_CACHE_BYTES is greater than
dma_get_cache_alignment() on sysmtes that can not allocate coherent memory
(some old systems can't).

James Bottomley exmplained that this is necesary because the driver packs the
set of mailboxes into a single coherent area and separates the different
usages by a L1 cache stride.  So it's fatal if the dma

He also pointed out that we can kill this checking because we don't hit this
BUG_ON on all architectures that actually use the driver.

(akpm: stolen from the scsi tree because
dma-mapping-remove-dma_is_consistent-api.patch needs it)
