5d8c61bc28 USB: io_ti: fix sysfs-attribute creation
Make sure port data is initialised before creating sysfs attributes to
avoid a race.

A recent patch ("USB: io_ti: fix port-data memory leak") got the
sysfs-attribute creation and port-data initialisation ordering wrong.

Make sure sysfs attributes are created at port probe.

A recent patch ("USB: iuu_phoenix: fix port-data memory leak") removed
the sysfs-attribute creation by mistake.

db5c8b5244 USB: fix port probing and removal in garmin_gps
This patch (as1615) fixes a bug in the Garmin USB serial driver.  It
uses attach, disconnect, and release routines to carry out actions
that should be handled by port_probe and port_remove routines, because
they access port-specific data.

The bug causes an oops when the device in unplugged, because the
private data for each port structure now gets erased when the port is
unbound from the driver, resulting in a null-pointer dereference.

b001b29791 USB 3.0 Link PM fixes.
Hi Greg,
 
 Here's four fixes for the USB 3.0 Link Power Management code.  They
 work around some USB 3.0 devices that don't support LPM, like the
 Western Digital My Passport hard drive.  They also fix an LPM disable
 ref count bug that would cause LPM to remain disabled for a device
 after a failed probe.
 
 Please queue for 3.7 after the merge window closes.  Several patches are
 marked for stable.

dba141601d dm: store dm_target_io in bio front_pad
Use the recently-added bio front_pad field to allocate struct dm_target_io.

Prior to this patch, dm_target_io was allocated from a mempool. For each
dm_target_io, there is exactly one bio allocated from a bioset.

This patch merges these two allocations into one allocation: we create a
bioset with front_pad equal to the size of dm_target_io so that every
bio allocated from the bioset has sizeof(struct dm_target_io) bytes
before it. We allocate a bio and use the bytes before the bio as
dm_target_io.

_tio_cache is removed and the tio_pool mempool is now only used for
request-based devices.

This idea was introduced by Kent Overstreet.

28eed34e76 dm thin: support discard with non power of two block size
Support discards when the pool's block size is not a power of 2.
The block layer assumes discard_granularity is a power of 2 (in
blkdev_issue_discard), so we set this to the largest power of 2 that is
a divides into the number of sectors in each block, but never less than
DATA_DEV_BLOCK_SIZE_MIN_SECTORS.

This patch eliminates the "Discard support must be disabled when the
block size is not a power of 2" constraint that was imposed in commit
55f2b8b ("dm thin: support for non power of 2 pool blocksize").  That
commit was incomplete: using a block size that is not a power of 2
shouldn't mean disabling discard support on the device completely.

Merge tag 'stable/for-linus-3.7-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen fixes from Konrad Rzeszutek Wilk:
 "This has four bug-fixes and one tiny feature that I forgot to put
  initially in my tree due to oversight.

  The feature is for kdump kernels to speed up the /proc/vmcore reading.
  There is a ram_is_pfn helper function that the different platforms can
  register for.  We are now doing that.

  The bug-fixes cover some embarrassing struct pv_cpu_ops variables
  being set to NULL on Xen (but not baremetal).  We had a similar issue
  in the past with {write|read}_msr_safe and this fills the three
  missing ones.  The other bug-fix is to make the console output (hvc)
  be capable of dealing with misbehaving backends and not fall flat on
  its face.  Lastly, a quirk for older XenBus implementations that came
  with an ancient v3.4 hypervisor (so RHEL5 based) - reading of certain
  non-existent attributes just hangs the guest during bootup - so we
  take precaution of not doing that on such older installations.

  Feature:
   - Register a pfn_is_ram helper to speed up reading of /proc/vmcore.
  Bug-fixes:
   - Three pvops call for Xen were undefined causing BUG_ONs.
   - Add a quirk so that the shutdown watches (used by kdump) are not
     used with older Xen (3.4).
   - Fix ungraceful state transition for the HVC console."

cb6b6df111 xen/pv-on-hvm kexec: add quirk for Xen 3.4 and shutdown watches.
The commit 254d1a3f02, titled
"xen/pv-on-hvm kexec: shutdown watches from old kernel" assumes that the
XenBus backend can deal with reading of values from:
 "control/platform-feature-xs_reset_watches":

    ... a patch for xenstored is required so that it
    accepts the XS_RESET_WATCHES request from a client (see changeset
    23839:42a45baf037d in xen-unstable.hg). Without the patch for xenstored
    the registration of watches will fail and some features of a PVonHVM
    guest are not available. The guest is still able to boot, but repeated
    kexec boots will fail."

Sadly this is not true when using a Xen 3.4 hypervisor and booting a PVHVM
guest. We end up hanging at:

  err = xenbus_scanf(XBT_NIL, "control",
                        "platform-feature-xs_reset_watches", "%d", &supported);

This can easily be seen with guests hanging at xenbus_init:

NX (Execute Disable) protection: active
SMBIOS 2.4 present.
DMI: Xen HVM domU, BIOS 3.4.0 05/13/2011
Hypervisor detected: Xen HVM
Xen version 3.4.
Xen Platform PCI: I/O protocol version 1
... snip ..
calling  xenbus_init+0x0/0x27e @ 1

Reverting the commit or using the attached patch fixes the issue. This fix
checks whether the hypervisor is older than 4.0 and if so does not try to
perform the read.

17b572e820 kdb,vt_console: Fix missed data due to pager overruns
It is possible to miss data when using the kdb pager.  The kdb pager
does not pay attention to the maximum column constraint of the screen
or serial terminal.  This result is not incrementing the shown lines
correctly and the pager will print more lines that fit on the screen.
Obviously that is less than useful when using a VGA console where you
cannot scroll back.

The pager will now look at the kdb_buffer string to see how many
characters are printed.  It might not be perfect considering you can
output ASCII that might move the cursor position, but it is a
substantially better approximation for viewing dmesg and trace logs.

This also means that the vt screen needs to set the kdb COLUMNS
variable.

24b8592ec0 kgdboc: Accept either kbd or kdb to activate the vga + keyboard kdb shell
It is a common enough mistake for people to specify "kdb" when they
meant to type "kbd" that the kgdboc can just accept both since they
both mean the same thing anyway.  Specifically it is for the case
where you want kdb to be active on your graphics console + keyboard
(where kbd was the original abbreviation for keyboard).

With this change kgdboc will now accept either to mean the same thing:
   kgdboc=kbd
   kgdboc=kdb

4f1cd91497 Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull second set of media updates from Mauro Carvalho Chehab:
 "Despite its size, most of the stuff here is trivial.  This series
  contains:

   - s5p-mfc: additions at the driver and at the core to support H.264
     hardware codec;
   - Some improvements at s5p and davinci embedded drivers;
   - Some V4L2 compliance fixes applied on a few drivers;
   - Several random trivial patches, including several fixes and a few
     new board support additions;

  Notes:

   1) Some Exynos media patches were dependent on some -arm fixes that
      got merged on changeset 782cd9e.  That's why this pull request is
      based that changeset.

   2) As promised, I reviewed the pending VB2 DMABUF series.

      While setting a test environment, it was noticed that the upstream
      support for Samsung Exynos 4 boards (smdk310 and Origen) are
      broken upstream, likely due to regressions: both defconfigs are
      wrong and regulator settings for both boards are broken.  That,
      allied with some bug at the dummy regulator driver, causes OOPSes
      during boot time.

      Long story short: even fixing the above, the proposed patches
      OOPSed when running the DMABUF test.  Not sure yet if the OOPSes
      are due to some other undetected regressions, or due to some bug
      on the patches.

      Due to the above, DMABUF patches for vb2 got NACKed for 3.7."
