Commit 3e721aeb
("crypto: talitos - handle descriptor not found in error path")
tried to address the fact that CDPR (Current Descriptor Pointer Register)
is unreliable.

As it turns out, there are still issues in the function detecting the
offending descriptor:
-only 32 bits of the descriptor address are read, however the address is
36-bit - since reset_channel() initializes channels with EAE (extended
address) bit set
-reading CDPR can return zero in cur_desc; when searching the channel
fifo for this address, cur_desc == dma_desc (= 0) case might happen,
leading to an oops when trying to return desc->hdr (desc is zero)
-read channel's .tail only once; the tail is a moving target; use a
local variable for the end of search condition

In omap_sham_probe() and omap_sham_remove(), 'dd->dma_lch'
is released without checking to see if it was successfully
requested or not.  This is a bug and was identified and
reported by Dan Carpenter here:

	http://www.spinics.net/lists/devicetree/msg11023.html

Add code to only release 'dd->dma_lch' when its not NULL
(that is, when it was successfully requested).

Commit d8a32ac2 (crypto: testmgr - make
test_aead also test 'dst != src' code paths) added support for different
source and destination buffers in test_aead.

This patch modifies the source and destination buffer lengths accordingly:
the lengths are not equal since encryption / decryption adds / removes
the ICV.

For aead case when source and destination buffers are different,
there is an incorrect assumption that the source length includes the ICV

There are cases when cryptlen can be zero in crypto_ccm_auth():
-encryptiom: input scatterlist length is zero (no plaintext)
-decryption: input scatterlist contains only the mac
plus the condition of having different source and destination buffers
(or else scatterlist length = max(plaintext_len, ciphertext_len)).

These are not handled correctly, leading to crashes like:

The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain
function to chain two scatterlists, but the chain pointer indication
bit is not set.  When the resulting scatterlist is used, for example,
by sg_nents to count the number of scatterlist entries, a segfault occurs
because sg_nents does not follow the chain pointer to the chained scatterlist.

Update scatterwalk_sg_chain to set the chain pointer indication bit as is
done by the sg_chain function.

Pull SCSI target updates from Nicholas Bellinger:
 "Things have been quiet this round with mostly bugfixes, percpu
  conversions, and other minor iscsi-target conformance testing changes.

  The highlights include:

   - Add demo_mode_discovery attribute for iscsi-target (Thomas)
   - Convert tcm_fc(FCoE) to use percpu-ida pre-allocation
   - Add send completion interrupt coalescing for ib_isert
   - Convert target-core to use percpu-refcounting for se_lun
   - Fix mutex_trylock usage bug in iscsit_increment_maxcmdsn
   - tcm_loop updates (Hannes)
   - target-core ALUA cleanups + prep for v3.14 SCSI Referrals support (Hannes)

  v3.14 is currently shaping to be a busy development cycle in target
  land, with initial support for T10 Referrals and T10 DIF currently on
  the roadmap"

Pull networking fixes from David Miller:

 1) Fix memory leaks and other issues in mwifiex driver, from Amitkumar
    Karwar.

 2) skb_segment() can choke on packets using frag lists, fix from
    Herbert Xu with help from Eric Dumazet and others.

 3) IPv4 output cached route instantiation properly handles races
    involving two threads trying to install the same route, but we
    forgot to propagate this logic to input routes as well.  Fix from
    Alexei Starovoitov.

 4) Put protections in place to make sure that recvmsg() paths never
    accidently copy uninitialized memory back into userspace and also
    make sure that we never try to use more that sockaddr_storage for
    building the on-kernel-stack copy of a sockaddr.  Fixes from Hannes
    Frederic Sowa.

 5) R8152 driver transmit flow bug fixes from Hayes Wang.

 6) Fix some minor fallouts from genetlink changes, from Johannes Berg
    and Michael Opdenacker.

 7) AF_PACKET sendmsg path can race with netdevice unregister notifier,
    fix by using RCU to make sure the network device doesn't go away
    from under us.  Fix from Daniel Borkmann.

current_headset_type should be of the HEADSET_TYPE enum, not the
HEADSET_MODE enum. Since ALC_HEADSET_TYPE_UNKNOWN and ALC_HEADSET_MODE_UNKNOWN
are both 0, this patch is just janitorial.

Some models (or maybe depending on BIOS version) of Sony VAIO with
ALC260 give no proper pin configurations as default, resulting in the
non-working speaker, etc.  Just provide the whole pin configurations
via a fixup.
