91978465b1 [SCSI] zfcp: Reorder registration of initial SCSI device
Make sure that the rport registration did complete and then register
SCSI device directly. Otherwise the unit_enqueue would race with the
call to zfcp_scsi_queue_unit_register.

    [SCSI] ipr: improve interrupt service routine performance

That patch is reverted with this one.  A new patch will be submitted
once the issue is better understood and properly handled in the driver.

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.

250ae982e2 [SCSI] bnx2i: Added chip cleanup for the remove module path
In the case when an ep_connect request is interrupted due to route
request stall, if the iSCSI daemon is terminated by the user, the chip
will be left in a state which will not get cleaned up upon module
removal.  Upon module reload, when the same context id is used for a
new connection, chip panic would occur.

a4dc090b6c firewire: ohci: work around VIA and NEC PHY packet reception bug
VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.

12acd90f0b drm/radeon/kms: remove stray radeon_i2c_destroy
I missed this one in the i2c unification patch.  This
is handled in the core radeon i2c code now.

    drm_mm: extract check_free_mm_node

I've botched up the range-restriction checks. The result is usually
an X server dying with SIGBUS in libpixman (software fallback rendering).
Change the code to adjust the start and end for range restricted
allocations. IMHO this even makes the code a bit clearer.

Fixes regression bug: https://bugs.freedesktop.org/show_bug.cgi?id=29738

ab699ec64a drm/nouveau: drop drm_global_mutex before sleeping in submission path
If we keep hold of the mutex here, the process which currently holds the
buffer object will never be able to release it, causing a deadlock.

fe5f098055 qlge: reset the chip before freeing the buffers
Qlge is freeing the buffers before stopping the card DMA, and
this can cause some severe error, as a EEH event on PPC.

This patch just stop the card and then free the resources.
