bc9627e7e9 via-velocity: fix netif_receive_skb use in irq disabled section.
2fdac010bd ("via-velocity.c: update napi
implementation") overlooked an irq disabling spinlock when the Rx part
of the NAPI poll handler was converted from netif_rx to netif_receive_skb.

NAPI Rx processing can be taken out of the locked section with a pair of
napi_{disable / enable} since it only races with the MTU change function.

An heavier rework of the NAPI locking would be able to perform NAPI Tx
before Rx where I simply removed one of velocity_tx_srv calls.

Marc Kleine-Budde says:

====================
here's a pull request for v3.13, i.e. net/master. It consists of a patch by
Oliver Hartkopp which fixes some corner cases in the interrupt handler of the
sja1000 driver. Then there are two patches for the c_can dirver. One by me,
which fixes a runtime pm related "scheduling while atomic" error and patch by
Holger Bechtold that fixes the calculation of the transmitted bytes.

The fourth patch is by me, it corrects the clock usage in the flexcan
driver.

6eabca54d6 sctp: Restore 'resent' bit to avoid retransmitted chunks for RTT measurements
Currently retransmitted DATA chunks could also be used for
RTT measurements since there are no flag to identify whether
the transmitted DATA chunk is a new one or a retransmitted one.
This problem is introduced by commit ae19c5486 ("sctp: remove
'resent' bit from the chunk") which inappropriately removed the
'resent' bit completely, instead of doing this, we should set
the resent bit only for the retransmitted DATA chunks.

5e53e689b7 genetlink/pmcraid: use proper genetlink multicast API
The pmcraid driver is abusing the genetlink API and is using its
family ID as the multicast group ID, which is invalid and may
belong to somebody else (and likely will.)

Make it use the correct API, but since this may already be used
as-is by userspace, reserve a family ID for this code and also
reserve that group ID to not break userspace assumptions.

My previous patch broke event delivery in the driver as I missed
that it wasn't using the right API and forgot to update it later
in my series.

While changing this, I noticed that the genetlink code could use
the static group ID instead of a strcmp(), so also do that for
the VFS_DQUOT family.

fe9d04afe9 bonding: disable arp and enable mii monitoring when bond change to no uses arp mode
Because the ARP monitoring is not support for 802.3ad, but I still
could change the mode to 802.3ad from ab mode while ARP monitoring
is running, it is incorrect.

So add a check for 802.3ad in bonding_store_mode to fix the problem,
and make a new macro BOND_NO_USES_ARP() to simplify the code.

v2: according to the Dan Williams's suggestion, bond mode is the most
    important bond option, it should override any of the other sub-options.
    So when the mode is changed, the conficting values should be cleared
    or reset, otherwise the user has to duplicate more operations to modify
    the logic. I disable the arp and enable mii monitoring when the bond mode
    is changed to AB, TB and 8023AD if the arp interval is true.

v3: according to the Nik's suggestion, the default value of miimon should need
    a name, there is several place to use it, and the bond_store_arp_interval()
    could use micro BOND_NO_USES_ARP to make the code more simpify.

31e20bad8d diag: warn about missing first netlink attribute
The first netlink attribute (value 0) must always be defined as none/unspec.
This is correctly done in inet_diag.h, but other diag interfaces are wrong.

Because we cannot change an existing API, I add a comment to point the mistake
and avoid to propagate it in a new diag API in the future.

08332dff8a irqchip: Gic: fix boot for chained gics
As of c0114709ed: "irqchip: gic: Perform the gic_secondary_init() call

Realview EB ARM11MPCore) will result in the gic_cpu_notifier being

platform unbootable.

This patch ensures that we only register the notifier for the first
gic, allowing platforms with chained gics to boot. At the same time we
limit the pointlessly duplicated calls to set_smp_cross_call and
set_handle_irq to the first gic registered.

bbf9c8934b crypto: caam - fix aead sglen for case 'dst != src'
For aead case when source and destination buffers are different,
there is an incorrect assumption that the source length includes the ICV
length. Fix this, since it leads to an oops when using sg_count() to
find the number of nents in the scatterlist:

5638cabf3e crypto: ccm - Fix handling of zero plaintext when computing mac
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:

Some s390 crypto algorithms incorrectly use the crypto_tfm structure to
store private data. As the tfm can be shared among multiple threads, this
can result in data corruption.

This patch fixes aes-xts by moving the xts and pcc parameter blocks from

41da8b5adb crypto: scatterwalk - Set the chain pointer indication bit
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.

2ded3e5b61 ALSA: hda - Check leaf nodes to find aamix amps
The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself.  But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls.  This is a regression
compared with the previous static quirks.

This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.

14058d20c1 lockref: include mutex.h rather than reinvent arch_mutex_cpu_relax
arch_mutex_cpu_relax is already conditionally defined in mutex.h, so
simply include that header rather than replicate the code here.

dad337501d remove obsolete references to powertweak
This tool hasn't been maintained in over a decade, and is pretty much
useless these days.  Let's pretend it never happened.

Also remove a long-dead email address.

Pull powerpc fixes from Ben Herrenschmidt:
 "The main thing that caused problem was that CONFIG_CPU_LITTLE_ENDIAN
  got turned on with allyesconfig and such, which is not a very good
  idea especially since it requires a newer toolchain than what most
  people have.

  So we turned it into a choice instead that defaults to big endian"

6d183de407 md/raid5: fix newly-broken locking in get_active_stripe.
commit 566c09c534 raid5: relieve lock contention in get_active_stripe()

modified the locking in get_active_stripe() reducing the range
protected by the (highly contended) device_lock.
Unfortunately it reduced the range too much opening up some races.

One race can occur if get_priority_stripe runs between the
test on sh->count and device_lock being taken.
This will mean that sh->lru is not empty while get_active_stripe
thinks ->count is zero resulting in a 'BUG' firing.

Another race happens if __release_stripe is called immediately
after sh->count is tested and found to be non-zero.  If STRIPE_HANDLE
is not set, get_active_stripe should increment ->active_stripes
when it increments ->count from 0, but as it didn't think it was 0,
it doesn't.

Extending device_lock to cover the test on sh->count close these
races.

While we are here, fix the two BUG tests:
 -If count is zero, then lru really must not be empty, or we've
  lock the stripe_head somehow - no other tests are relevant.
 -STRIPE_ON_RELEASE_LIST is completely independent of ->lru so
  testing it is pointless.
