cbc44dbe1f cpts: fix build error by removing useless code.
The cpts driver tries to obtain the input clock frequency by calling the
clock's internal 'recalc' method. Since <plat/clock.h> has been removed,
this code can no longer compile.

However, the driver never makes use of the frequency value, so this patch
fixes the issue by removing the offending code altogether.

9fdc6bef5f tuntap: dont use a private kmem_cache
Commit 96442e4242 (tuntap: choose the txq based on rxq)
added a per tun_struct kmem_cache.

As soon as several tun_struct are used, we get an error
because two caches cannot have same name.

Use the default kmalloc()/kfree_rcu(), as it reduce code
size and doesn't have performance impact here.

b7dfde956d Some nice cleanups, and even a patch my wife did as a "live" demo for
Latinoware 2012.
 
 There's a slightly non-trivial merge in virtio-net, as we cleaned up the
 virtio add_buf interface while DaveM accepted the mq virtio-net patches.
 
 You can see my solution in my pending-rebases branch, if that helps, but I
 know you love merging:

4945106d21 ksz884x: fix receive polling race condition
The ksz884x driver does receive processing in a custom tasklet, and
seems to be assuming that since it takes its private interface spinlock
with spin_lock_irq(), it won't be running concurrently with its own
interrupt handler, as it cannot be preempted by it, but since its
interrupt handler doesn't do any locking whatsoever, the receive
processing tasklet and interrupt handler can end up running concurrently
on different CPUs.

As a result of this, the ksz884x receive path ends up locking up fairly
easily, when the receive processing tasklet's reenabling of receive
interrupts (due to it being done with polling the receive ring) races
with the interrupt handler's disabling of receive interrupts (due to a
new receive interrupt coming in) resulting in the receive interrupt
being masked but the receive processing tasklet not being scheduled.

Fix this by making the ksz884x interrupt handler take its private
interface spinlock.  This requires upgrading the spin_lock() in the
transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ
handler can preempt transmit cleanup and deadlock the system, but
with those two changes, no more receive lockups have been observed.

c1e37ea287 net: fec: forbid FEC_PTP on SoCs that do not support
Beside imx6q, the kernel built from imx_v6_v7_defconfig is also
supposed to be running on other IMX SoCs that do not have the PTP
block.  Before fec driver gets fixed to run-time detect target hardware
rather than conditional compiling with #ifdef CONFIG_FEC_PTP, let's
give it a quick fix in Kconfig to forbid FEC_PTP on those IMX SoCs that
do not support PTP.

d23e946cb6 be2net: fix wrong frag_idx reported by RX CQ
The RX CQ can report completions with invalid frag_idx when the RXQ that
was *previously* using it, was not cleaned up properly. This hits
a BUG_ON() in be2net.

When completion coalescing is enabled on a CQ, an explicit CQ-notify
(with rearm) is needed for each compl, to flush partially coalesced CQ
entries that are pending DMA.

In be_close(), this fix now notifies CQ for each compl, waits explicitly
for the flush compl to arrive and complains if it doesn't arrive.

Also renaming be_crit_error() to be_hw_error() as it's the more
appropriate name and to convey that we don't wait for the flush compl
only when a HW error has occurred.

6ee57bcc1e virtio-net: correct capacity math on ring full
Capacity math on ring full is wrong: we are
looking at num_sg but that might be optimistic
because of indirect buffer use.

The implementation also penalizes fast path
with extra memory accesses for the benefit of
ring full condition handling which is slow path.

It's easy to query ring capacity so let's do just that.

This change also makes it easier to move vnet header
for tx around as follow-up patch does.

If there are only Atheros cards that do not require ATH_COMMON, whole

won't compile in this case.

In commit 'mac80211: support radiotap vendor namespace RX data'
new fields were added to 'struct ieee80211_rx_status' and those
fileds must be zeroed. However the rt2x00 driver stores driver
specific data in the cb array of the rx skbs, so the fields
might contain garbage and this can cause unexpected behaviour.

The rt2x00 driver from the compat-wireless-2012-12-01
tarball caused the following warning:

76fe45812a tuntap: reset network header before calling skb_get_rxhash()
Commit 499744209b (tuntap: dont use skb after netif_rx_ni(skb))
introduced another bug.

skb_get_rxhash() needs to access the network header, and it was
set for us in netif_rx_ni().

We need to reset network header or else skb_flow_dissect() behavior
is out of control.

4008e97f86 tuntap: fix ambigious multiqueue API
The current multiqueue API is ambigious which may confuse both user and LSM to
do things correctly:

- Both TUNSETIFF and TUNSETQUEUE could be used to create the queues of a tuntap
  device.
- TUNSETQUEUE were used to disable and enable a specific queue of the
  device. But since the state of tuntap were completely removed from the queue,
  it could be used to attach to another device (there's no such kind of
  requirement currently, and it needs new kind of LSM policy.
- TUNSETQUEUE could be used to attach to a persistent device without any
  queues. This kind of attching bypass the necessary checking during TUNSETIFF
  and may lead unexpected result.

So this patch tries to make a cleaner and simpler API by:

- Only allow TUNSETIFF to create queues.
- TUNSETQUEUE could be only used to disable and enabled the queues of a device,
  and the state of the tuntap device were not detachd from the queues when it
  was disabled, so TUNSETQUEUE could be only used after TUNSETIFF and with the
   same device.

This is done by introducing a list which keeps track of all queues which were
disabled. The queue would be moved between this list and tfiles[] array when it
was enabled/disabled. A pointer of the tun_struct were also introdued to track
the device it belongs to when it was disabled.

After the change, the isolation between management and application could be done
through: TUNSETIFF were only called by management software and TUNSETQUEUE were
only called by application.For LSM/SELinux, the things left is to do proper
check during tun_set_queue() if needed.

Pull networking changes from David Miller:

1) Allow to dump, monitor, and change the bridge multicast database
   using netlink.  From Cong Wang.

2) RFC 5961 TCP blind data injection attack mitigation, from Eric
   Dumazet.

3) Networking user namespace support from Eric W. Biederman.

4) tuntap/virtio-net multiqueue support by Jason Wang.

5) Support for checksum offload of encapsulated packets (basically,
   tunneled traffic can still be checksummed by HW).  From Joseph
   Gasparakis.

6) Allow BPF filter access to VLAN tags, from Eric Dumazet and
   Daniel Borkmann.

7) Bridge port parameters over netlink and BPDU blocking support
   from Stephen Hemminger.

8) Improve data access patterns during inet socket demux by rearranging
   socket layout, from Eric Dumazet.

9) TIPC protocol updates and cleanups from Ying Xue, Paul Gortmaker, and
   Jon Maloy.

10) Update TCP socket hash sizing to be more in line with current day
    realities.  The existing heurstics were choosen a decade ago.
    From Eric Dumazet.

11) Fix races, queue bloat, and excessive wakeups in ATM and
    associated drivers, from Krzysztof Mazur and David Woodhouse.

12) Support DOVE (Distributed Overlay Virtual Ethernet) extensions
    in VXLAN driver, from David Stevens.

13) Add "oops_only" mode to netconsole, from Amerigo Wang.

14) Support set and query of VEB/VEPA bridge mode via PF_BRIDGE, also
    allow DCB netlink to work on namespaces other than the initial
    namespace.  From John Fastabend.

15) Support PTP in the Tigon3 driver, from Matt Carlson.

16) tun/vhost zero copy fixes and improvements, plus turn it on
    by default, from Michael S. Tsirkin.

17) Support per-association statistics in SCTP, from Michele
    Baldessari.

And many, many, driver updates, cleanups, and improvements.  Too
numerous to mention individually.
