Pull networking fixes from David Miller:
1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't
figure out why it breaks things.
2) Fix comparison in netfilter ipset's hash_netnet4_data_equal(), it
was basically doing "x == x", from Dave Jones.
3) Freescale FEC driver was DMA mapping the wrong number of bytes, from
Sebastian Siewior.
4) Blackhole and prohibit routes in ipv6 were not doing the right thing
because their ->input and ->output methods were not being assigned
correctly. Now they behave properly like their ipv4 counterparts.
From Kamala R.
5) Several drivers advertise the NETIF_F_FRAGLIST capability, but
really do not support this feature and will send garbage packets if
fed fraglist SKBs. From Eric Dumazet.
6) Fix long standing user triggerable BUG_ON over loopback in RDS
protocol stack, from Venkat Venkatsubra.
7) Several not so common code paths can potentially try to invoke
packet scheduler actions that might be NULL without checking. Shore
things up by either 1) defining a method as mandatory and erroring
on registration if that method is NULL 2) defininig a method as
optional and the registration function hooks up a default
implementation when NULL is seen. From Jamal Hadi Salim.
8) Fix fragment detection in xen-natback driver, from Paul Durrant.
9) Kill dangling enter_memory_pressure method in cg_proto ops, from
Eric W Biederman.
10) SKBs that traverse namespaces should have their local_df cleared,
from Hannes Frederic Sowa.
11) IOCB file position is not being updated by macvtap_aio_read() and
tun_chr_aio_read(). From Zhi Yong Wu.
12) Don't free virtio_net netdev before releasing all of the NAPI
instances. From Andrey Vagin.
13) Procfs entry leak in xt_hashlimit, from Sergey Popovich.
14) IPv6 routes that are no cached routes should not count against the
garbage collection limits. We had this almost right, but were
missing handling addrconf generated routes properly. From Hannes
Frederic Sowa.
15) fib{4,6}_rule_suppress() have to consider potentially seeing NULL
route info when they are called, from Stefan Tomanek.
16) TUN and MACVTAP have had truncated packet signalling for some time,
fix from Jason Wang.
17) Fix use after frrr in __udp4_lib_rcv(), from Eric Dumazet.
18) xen-netback does not interpret the NAPI budget properly for TX work,
fix from Paul Durrant.

Commit 89ce376c6bdc (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.

Commit e40526cb20b5 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 e40526cb20b5.

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 5d69e0076a72 (net: davinci_emac: switch to
new mdio).

Pull device mapper fixes from Mike Snitzer:
"A set of device-mapper fixes for 3.13.
A fix for possible memory corruption during DM table load, fix a
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"

The cache target's invalidate_cblocks message allows cache block
(cblock) ranges to be expressed with: <cblock start>-<cblock end>
The range's <cblock end> value is "one past the end", so the range
includes <cblock start> through <cblock end>-1.

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"

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().

Endianness issues are now consistent as per the documentation in
host/mic_virtio.h. Sparse warnings related to endianness are also fixed.
Note that the MIC driver implementation assumes that the host can be
both BE or LE whereas the card is always LE.

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.

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 aea585ef8fa65163 introduced as
part of sysfs changes in 3.13-rc1. A seek to 0 has been introduced to
fix it.

Pull ARM SoC fixes from Olof Johansson:
"Another batch of fixes for ARM SoCs for 3.13. The diffstat is large,
mostly because of:
- Another set of fixes to fix regressions caused by moving OMAP from
board files to DT. Tony thinks this was the last major set of
fixes, with maybe just a few small patches to follow.
- More fixes for Marvell platforms, most dealing with misdescribed
PCIe hardware, i.e. incorrect number of busses on some SoCs, etc.
The line delta adds up due to various ranges moving around when
this is fixed.
But there's also:
- Some smaller tweaks to defconfigs to make more boards bootable in
my test setup for better coverage.
- There are also a few other smaller fixes, a short series for at91,
a couple of reverts for ux500, etc"

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.

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.

From Stephen Warren:
ARM: tegra: Trusted Foundations firmware support
Add support for the Trusted Foundations secure-mode firmware, as found
on NVIDIA SHIELD. This allows Linux to run in non-secure mode on this
board; all previous Tegra support has assumed the kernel is running in
secure mode.
(The base TF support has been discussed back and forth a lot; for now
the most logical place for it seems to be under arch/arm, so we're adding
it here. We can move it out to a common location in the future if needed).
