Pull SCSI fixes from James Bottomley:
 "This is a set of four bug fixes.

  The isci one is an obvious thinko (using request buffer instead of
  response buffer) which causes a command to fail.

  The three others are DIF/DIX updates which are required because
  they're part of a series of ten patches, the other seven of which went
  into the block layer during the merge window meaning our current
  DIF/DIX implementation is broken without these three.

 "Here are some USB fixes for the 3.7 tree.

  Nothing huge here, just a number of tiny bugfixes resolving issues
  that have been found, and two reverts of patches that were found to
  have caused problems.

  All of these have been in linux-next already.

[SCSI] sd: Implement support for WRITE SAME

2012-11-14T06:45:42+00:00

Implement support for WRITE SAME(10) and WRITE SAME(16) in the SCSI disk
driver.

 - We set the default maximum to 0xFFFF because there are several
   devices out there that only support two-byte block counts even with
   WRITE SAME(16). We only enable transfers bigger than 0xFFFF if the
   device explicitly reports MAXIMUM WRITE SAME LENGTH in the BLOCK
   LIMITS VPD.

 - max_write_same_blocks can be overriden per-device basis in sysfs.

 - The UNMAP discovery heuristics remain unchanged but the discard
   limits are tweaked to match the "real" WRITE SAME commands.

 - In the error handling logic we now distinguish between WRITE SAME
   with and without UNMAP set.

The discovery process heuristics are:

 - If the device reports a SCSI level of SPC-3 or greater we'll issue
   READ SUPPORTED OPERATION CODES to find out whether WRITE SAME(16) is
   supported. If that's the case we will use it.

 - If the device supports the block limits VPD and reports a MAXIMUM
   WRITE SAME LENGTH bigger than 0xFFFF we will use WRITE SAME(16).

 - Otherwise we will use WRITE SAME(10) unless the target LBA is beyond
   0xFFFFFFFF or the block count exceeds 0xFFFF.

 - no_write_same is set for ATA, FireWire and USB.

[SCSI] Add a report opcode helper

2012-11-14T05:11:31+00:00

The REPORT SUPPORTED OPERATION CODES command can be used to query
whether a given opcode is supported by a device. Add a helper function
that allows us to look up commands.

We only issue RSOC if the device reports compliance with SPC-3 or
later. But to err on the side of caution we disable the command for ATA,
FireWire and USB.

Revert "USB/host: Cleanup unneccessary irq disable code"

2012-11-13T18:52:52+00:00

This reverts commit 73d4066055e0e2830533041f4b91df8e6e5976ff.

Martin Steigerwald reported that this change caused a hard lockup when
using USB if threadirqs are enabled.  Thomas pointed out that this patch
is incorrect, and can cause problems.  So revert it to get the
previously working functionality back.

USB: keyspan: fix typo causing GPF on open

2012-11-13T18:45:16+00:00

Commit f79b2d0f (USB: keyspan: fix NULL-pointer dereferences and
memory leaks) had a small typo which made the driver use wrong
offsets when mapping serial port private data.  This results in
in a GPF when the port is opened.

USB: fix build with XEN and EARLY_PRINTK_DBGP enabled but USB_SUPPORT disabled

2012-10-30T20:05:14+00:00

Since there's no possible caller of dbgp_external_startup() and
dbgp_reset_prep() when !USB_EHCI_HCD, there's no point in building and
exporting these functions in that case. This eliminates a build error
under the conditions listed in the subject, introduced with the merge
f1c6872e4980bc4078cfaead05f892b3d78dea64.
