Pull libata fixes from Tejun Heo:
 "There's one interseting commit - "libata, freezer: avoid block device
  removal while system is frozen".  It's an ugly hack working around a
  deadlock condition between driver core resume and block layer device
  removal paths through freezer which was made more reproducible by
  writeback being converted to workqueue some releases ago.  The bug has
  nothing to do with libata but it's just an workaround which is easy to
  backport.  After discussion, Rafael and I seem to agree that we don't
  really need kernel freezables - both kthread and workqueue.  There are
  few specific workqueues which constitute PM operations and require
  freezing, which will be converted to use workqueue_set_max_active()
  instead.  All other kernel freezer uses are planned to be removed,
  followed by the removal of kthread and workqueue freezer support,
  hopefully.

  Others are device-specific fixes.  The most notable is the addition of
  NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
  M500 SSDs which otherwise suffers data corruption"

b8bd6dc361 libata: disable a disk via libata.force params
A user on StackExchange had a failing SSD that's soldered directly
onto the motherboard of his system. The BIOS does not give any option
to disable it at all, so he can't just hide it from the OS via the
BIOS.

The old IDE layer had hdX=noprobe override for situations like this,
but that was never ported to the libata layer.

This patch implements a disable flag for libata.force.

Example use:

 libata.force=2.0:disable

[v2 of the patch, removed the nodisable flag per Tejun Heo]

93e1585e2c A set of device-mapper fixes for 3.13.

 possible leak of snapshot space in case of a crash, fix a possible
 deadlock due to a shared workqueue in the delay target, fix to
 initialize read-only module parameters that are used to export metrics
 for dm stats and dm bufio.
 
 Quite a few stable fixes were identified for both the thin-provisioning
 and caching targets as a result of increased regression testing using
 the device-mapper-test-suite (dmts).  The most notable of these are the
 reference counting fixes for the space map btree that is used by the
 dm-array interface -- without these the dm-cache metadata will leak,
 resulting in dm-cache devices running out of metadata blocks.  Also,
 some important fixes related to the thin-provisioning target's
 transition to read-only mode on error.

Merge tag 'keys-devel-20131210' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull misc keyrings fixes from David Howells:
 "These break down into five sets:

   - A patch to error handling in the big_key type for huge payloads.
     If the payload is larger than the "low limit" and the backing store
     allocation fails, then big_key_instantiate() doesn't clear the
     payload pointers in the key, assuming them to have been previously
     cleared - but only one of them is.

     Unfortunately, the garbage collector still calls big_key_destroy()
     when sees one of the pointers with a weird value in it (and not
     NULL) which it then tries to clean up.

   - Three patches to fix the keyring type:

     * A patch to fix the hash function to correctly divide keyrings off
       from keys in the topology of the tree inside the associative
       array.  This is only a problem if searching through nested
       keyrings - and only if the hash function incorrectly puts the a
       keyring outside of the 0 branch of the root node.

     * A patch to fix keyrings' use of the associative array.  The
       __key_link_begin() function initially passes a NULL key pointer
       to assoc_array_insert() on the basis that it's holding a place in
       the tree whilst it does more allocation and stuff.

       This is only a problem when a node contains 16 keys that match at
       that level and we want to add an also matching 17th.  This should
       easily be manufactured with a keyring full of keyrings (without
       chucking any other sort of key into the mix) - except for (a)
       above which makes it on average adding the 65th keyring.

     * A patch to fix searching down through nested keyrings, where any
       keyring in the set has more than 16 keyrings and none of the
       first keyrings we look through has a match (before the tree
       iteration needs to step to a more distal node).

     Test in keyutils test suite:

        http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=8b4ae963ed92523aea18dfbb8cab3f4979e13bd1

   - A patch to fix the big_key type's use of a shmem file as its
     backing store causing audit messages and LSM check failures.  This
     is done by setting S_PRIVATE on the file to avoid LSM checks on the
     file (access to the shmem file goes through the keyctl() interface
     and so is gated by the LSM that way).

     This isn't normally a problem if a key is used by the context that
     generated it - and it's currently only used by libkrb5.

     Test in keyutils test suite:

        http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=d9a53cbab42c293962f2f78f7190253fc73bd32e

   - A patch to add a generated file to .gitignore.

   - A patch to fix the alignment of the system certificate data such
     that it it works on s390.  As I understand it, on the S390 arch,
     symbols must be 2-byte aligned because loading the address discards
     the least-significant bit"

Commit 89ce376c6b (drivers/net: Use of_match_ptr() macro in smc91x.c)
added minimal device tree support to smc91x, but it's not working on
many platforms because of the lack of some key configuration bits.

Fix the issue by parsing the necessary configuration like the
smc911x driver is doing. As most smc91x users seem to use 16-bit
access, let's default to that if no reg-io-width is specified.

66e56cd46b packet: fix send path when running with proto == 0
Commit e40526cb20 introduced a cached dev pointer, that gets
hooked into register_prot_hook(), __unregister_prot_hook() to
update the device used for the send path.

We need to fix this up, as otherwise this will not work with
sockets created with protocol = 0, plus with sll_protocol = 0
passed via sockaddr_ll when doing the bind.

So instead, assign the pointer directly. The compiler can inline
these helper functions automagically.

While at it, also assume the cached dev fast-path as likely(),
and document this variant of socket creation as it seems it is
not widely used (seems not even the author of TX_RING was aware
of that in his reference example [1]). Tested with reproducer
from e40526cb20.

c1b96a236e [media] videobuf2: Add support for file access mode flags for DMABUF exporting
Currently it is not possible for userspace to map a DMABUF exported buffer
with write permissions. This patch allows to also pass O_RDONLY/O_RDWR when
exporting the buffer, so that userspace may map it with write permissions.

dd0df47dc3 net: davinci_emac: Fix platform data handling and make usable for am3517
When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.

Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.

Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e0076a (net: davinci_emac: switch to
new mdio).

b8be3a2279 Merge tag 'omap-for-v3.13/fixes-against-rc1-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:

Some omap related fixes that have come up with people moving to device
tree only based booting for omap2+.

The series contains a handful of fixes for the igep boards as they were
one of the first omap3 boards to jump over completely to device tree
based booting. So these can be considered regressions compared to
booting igep in legacy mode with board files in v3.12.

Also included are few other device tree vs legacy booting regressions:

- yet more missing omap3 .dtsi entries that have showed up booting
  various boards with device tree only

- n900 eMMC device tree fix

- fixes for beagle USB EHCI

- two fixes to make omap2420 MMC work

As we're moving omap2+ to be device tree only for v3.14, I'd like to
have v3.13 work equally well for legacy based booting and device tree
based booting. So there will be likely few more device tree related
booting patches trickling in.

This series also includes a regression fix for the omap timer posted
mode that may wrongly stay on from the bootloader for some SoCs.

23fd78d764 KEYS: Fix multiple key add into associative array
If sufficient keys (or keyrings) are added into a keyring such that a node in
the associative array's tree overflows (each node has a capacity N, currently
16) and such that all N+1 keys have the same index key segment for that level
of the tree (the level'th nibble of the index key), then assoc_array_insert()
calls ops->diff_objects() to indicate at which bit position the two index keys
vary.

However, __key_link_begin() passes a NULL object to assoc_array_insert() with
the intention of supplying the correct pointer later before we commit the
change.  This means that keyring_diff_objects() is given a NULL pointer as one
of its arguments which it does not expect.  This results in an oops like the
attached.

With the previous patch to fix the keyring hash function, this can be forced
much more easily by creating a keyring and only adding keyrings to it.  Add any
other sort of key and a different insertion path is taken - all 16+1 objects
must want to cluster in the same node slot.

This can be tested by:

	r=`keyctl newring sandbox @s`
	for ((i=0; i<=16; i++)); do keyctl newring ring$i $r; done

This should work fine, but oopses when the 17th keyring is added.

Since ops->diff_objects() is always called with the first pointer pointing to
the object to be inserted (ie. the NULL pointer), we can fix the problem by
changing the to-be-inserted object pointer to point to the index key passed
into assoc_array_insert() instead.

Whilst we're at it, we also switch the arguments so that they are the same as
for ->compare_object().

1e31aa9270 misc: mic: Fix user space namespace pollution from mic_common.h.
Avoid declaring ALIGN() and __aligned() in
include/uapi/linux/mic_common.h since they pollute user space
namespace. Also, mic_aligned_size() can be simply replaced simply by
sizeof() since all structures where mic_aligned_size() is used are
declared using __attribute__ ((aligned(8)));

Subject: Namespace pollution in mic_common.h

This puts two macros, ALIGN() and __aligned(), into arbitrary user space
namespace.  This really isn't safe or acceptable, especially since those
symbols are highly generic.
...
When these structures are forced-aligned, they will in fact have padding
automatically added by the compiler to an 8-byte boundary anyway, so
mic_aligned_size() does nothing.

286c24028c misc: mic: Bug fix for sysfs poll usage.
MIC user space daemon poll's on sysfs changes. The documentation for
sysfs_poll(...) in fs/sysfs/file.c states that "Once poll/select
indicates that the value has changed, you need to close and re-open the
file, or seek to 0 and read again". This step was missed out earlier and
resulted in the daemon spinning continuously rather than getting blocked
in 'poll'. This bug was exposed by commit aea585ef8f introduced as
part of sysfs changes in 3.13-rc1. A seek to 0 has been introduced to
fix it.

9cb238c00b mmc: omap: Fix I2C dependency and make driver usable with device tree
Some features can be configured by the companion I2C chips,
which may not be available at the probe time. Fix the issue
by returning -EPROBE_DEFER when the MMC controller slots
are not configured.

While at it, let's also add minimal device tree support so
omap24xx platforms can use this driver without legacy mode
since we claim to support device tree for mach-omap2 based
systems.

Although adding the minimal device tree support is not strictly
a fix, it does remove one of the last blockers for dropping a
bunch of legacy platform data for mach-omap2.

Mostly bugfixes and a few small code removals. Worth pointing out is:
 
 - A handful of more fixes to get DT enablement working properly on OMAP,
   finding new breakage of things that don't work quite right yet without
   the traditional board files. I expect a bit more of this to come in this

 - Implementation of power_down_finish() on vexpress, to make kexec work and
   to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
 - A handful of minor fixes for various platforms.

fd8e198cfc Documentation: gpiolib: document new interface
gpiolib now exports a new descriptor-based interface which deprecates
the older integer-based one. This patch documents this new interface and
also takes the opportunity to brush-up the GPIO documentation a little
bit.

The new descriptor-based interface follows the same consumer/driver
model as many other kernel subsystems (e.g. clock, regulator), so its
documentation has similarly been splitted into different files.

The content of the former documentation has been reused whenever it
made sense; however, some of its content did not apply to the new
interface anymore and have this been removed. Likewise, new sections
like the mapping of GPIOs to devices have been written from scratch.

The deprecated legacy-based documentation is still available, untouched,
under Documentation/gpio/gpio-legacy.txt.
