1f679cafd2 [SCSI] lpfc: Fix LS_RJT never sent by lpfc_els_unsol_event()
lpfc_els_unsol_event() checks rjt_err to determine is LS_RJT should be
sent.  However, rjt_err was set to LSEXP_NOTHING_ELSE (which is 0) in
cases where an LS_RJT should be sent, so rjt_err was never true.
Change lpfc_els_unsol_event() to set rjt_err to 1 when LS_RJT should
be sent.

06325e7459 [SCSI] lpfc: Add LP6000 PCI ID
Fix driver not seeing LP6000.  Fix: add PCI id to the pci_device_id
table and a short description for the HBA in get_hba_model_desc().
Also add a default clause to the switch statement that parses the
various PCI ID's.

564b296083 [SCSI] lpfc: Set max_sectors in host template
Add max_sectors to the driver host template and initialize it with
0xFFFF since the driver has no limitations on the size a transfer
contained by a scsi command and that fits within the sg_tablesize
provisioned by the driver.  This fixes a performance issue seen in
some configurations.

db468d108a [SCSI] lpfc: Fixes in mbox_timeout_handler
Analysis:

Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which
reads psli->mbox_active to determine the timeout mbox.  Timeout
handler then NULL's psli->mbox_active and calls
lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls
link_down().  link_down() now calls disc_done() which calls
mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which
goes back to read psli->mbox_active which is already NULL'ed.

Remove redundant if statement in lpfc_mbox_timeout_handler.  pmbox is
assigned psli->mbox_active so there is no need to check if it actually
equals psli->mbox_active.

9a8bc9b84b [SCSI] update spi transport class so that u320 Domain Validation works
There are several extra things that have to be considered when running
Domain Validation on a u320 target (notably how you fall back).

Hopefully this should help us when someone adds this transport class to
aic79xx.

I've tested this on the lsi1030, so I know it works correctly up to
u320.

521314c122 [SCSI] sg: Command completion after remove oops
A problem exists todayin the sg driver that if an SG_IO request is
outstanding to a device when it is removed from the system. The
system may oops if that command completes later in time.

1. sg_remove gets called
2. sg_remove calls sg_finish_req_req on all pending requests
   This removes the Sg_request's from the headrp list in the Sg_fd
3. The sleeping SG_IO ioctl is woken. It does nothing and returns.
4. The caller closes the fd, which invokes sg_release
5. sg_release calls sg_remove_sfp. It finds no outstanding commands
   since the headrp list is empty, so it calls __sg_remove_sfp,
   which frees the sfp.
6. Now when sg_cmd_done gets called, sg uses upper_private_data in
   the Scsi_Request, which should point to the srp, which has been
   freed, so it points to freed memory.
7. sg then dereferences the srp pointer to get the sfp, and we oops.

The fix is to NULL out the upper_private_data field in this path,
which sg_cmd_done already checks for, which will prevent the oops
from occurring.

c92715b3c2 [SCSI] fix slab corruption during ipr probe
With CONFIG_DEBUG_SLAB=y I see slab corruption messages during boot on
pSeries machines with IPR adapters with any 2.6.12-rc kernel.

The change which seems to have introduced the problem is "SCSI: revamp
target scanning routines" and may be found at:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111093946426333&w=2

In order to revert that in a 2.6.12-rc1 tree, I had to revert "target
code updates to support scanned targets" first:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111094132524649&w=2

With both patches reverted, the corruption messages go away.

I did some digging and the problem seems to be a refcounting issue in
__scsi_add_device.  The target gets freed in scsi_target_reap, and
then __scsi_add_device tries to do another device_put on it.

aa8f0dc6c3 libata: Fix use-after-iounmap
Jens Axboe pointed out that the iounmap() call in libata was occurring
too early, and some drivers (ahci, probably others) were using ioremap'd
memory after it had been unmapped.

The patch should address that problem by way of improving the libata
driver API:

* move ->host_stop() call after all ->port_stop() calls have occurred.

* create default helper function ata_host_stop(), and move iounmap()
call there.

* add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark).
sata_qstor appears to require the host-stop-before-port-stop ordering
that existed prior to applying the attached patch.

631e8a1398 [SCSI] TYPE_RBC cache fixes (sbp2.c affected)
a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h
	b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off
	c) relevant places in midlayer and sd.c taught to accept TYPE_RBC
	d) sd.c::sd_read_cache_type() looks into page 6 when dealing with
TYPE_RBC - these guys have writeback cache flag there and are not guaranteed
to have page 8 at all.
	e) sd_read_cache_type() got an extra sanity check - it checks that
it got the page it asked for before using its contents.  And screams if
mismatch had happened.  Rationale: there are broken devices out there that
are "helpful" enough to go for "I don't have a page you've asked for, here,
have another one".  For example, PL3507 had been caught doing just that...
	f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead
of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions
in there are gone now.

	Incidentally, I wonder if USB storage devices that have no
mode page 8 are simply RBC ones.  I haven't touched that, but it might
be interesting to check...

32529e0128 [PATCH] libata: Fix zero sg_dma_len() on 64-bit platform
When testing ATAPI PIO data transfer on the ppc64 platform,  __atapi_pio_bytes() got zero when
sg_dma_len() is used. I checked the <asm-ppc64/scatterlish.h>, the struct scatterlist is defined as:

struct scatterlist {
	struct page *page;
	unsigned int offset;
	unsigned int length;

	/* For TCE support */
	u32 dma_address;
	u32 dma_length;
};

#define sg_dma_address(sg)	((sg)->dma_address)
#define sg_dma_len(sg)		((sg)->dma_length)

So, if the scatterlist is not DMA mapped, sg_dma_len() will return zero on ppc64.
The same problem should occur on the x86-64 platform.
On the i386 platform, sg_dma_len() returns sg->length, that's why the problem does not occur on an i386.

Changes:
- Use sg->length if the scatterlist is not DMA mapped (yet).

60bf09a366 [PATCH] sata_svw: Add support for new device IDs
BCM5785 (HT1000) is a new southbridge from Serverworks/Broadcom that
incorporates 4 SATA ports in a single PCIX function. Functionally these
ports are similar to that in older devices like the Apple K2 and the
Frodo4/8. This patch adds support for the new PCI device ID along with a
blurb on what the various device IDs mean. Additionally in all devices
based on this SATA controller, the SATA ports appear as a single PCI
function. This is true for older Frodo8 devices as well. Hence the init
function should init all the ports present in the detected controller
(which could be 4 or 8).

c7525233d2 [SCSI] aic7xxx: make correct use of slave_alloc/destroy and remove the per device timer
The allocation of all of our components should be done in slave alloc.
Currently it's rather fancifully refcounted in the queuecommand
callback.  This patch moves allocation and destroy to their correct
places in slave_alloc/slave_destory.  Now we can guarantee that
everywhere a device is requested, it's actually been allocated, so don't
check for this anymore.

Additionally, the per device busy timer was the only source of potential
use after free.  It's been deleted because Linux does the correct thing
with busy returns, so there's no need to implement a separate timer in
the driver.

Finally, implement code that forces all the device parameters to zero
(i.e. async and narrow) in the slave alloc, inform the spi class of the
bios recorded maximums and wait until slave configure before trying
anything more adventurous.

New code from the Adaptec driver.  Performance enhancement for newer

- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
  requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup
