Pull networking fixes from David Miller:
 "First post-Sandy pull request"

 1) Fix antenna gain handling and initialization of chan->max_reg_power
    in wireless, from Felix Fietkau.

 2) Fix nexthop handling in H.232 conntrack helper, from Julian
    Anastasov.

 3) Only process 80211 mesh config header in certain kinds of frames,
    from Javier Cardona.

 4) 80211 management frame header length needs to be validated, from
    Johannes Berg.

 5) Don't access free'd SKBs in ath9k driver, from Felix Fietkay.

 6) Test for permanent state correctly in VXLAN driver, from Stephen
    Hemminger.

 7) BNX2X bug fixes from Yaniv Rosner and Dmitry Kravkov.

 8) Fix off by one errors in bonding, from Nikolay ALeksandrov.

 9) Fix divide by zero in TCP-Illinois congestion control.  From Jesper
    Dangaard Brouer.

10) TCP metrics code says "Yo dawg, I heard you like sizeof, so I did a
    sizeof of a sizeof, so you can size your size" Fix from Julian
    Anastasov.

11) Several drivers do mdiobus_free without first doing an
    mdiobus_unregister leading to stray pointer references.  Fix from
    Peter Senna Tschudin.

12) Fix OOPS in l2tp_eth_create() error path, it's another danling
    pointer kinda situation.  Fix from Tom Parkin.

13) Hardware driven by the vmxnet driver can't handle larger than 16K
    fragments, so split them up when necessary.  From Eric Dumazet.

14) Handle zero length data length in tcp_send_rcvq() properly.  Fix
    from Pavel Emelyanov.

Pavel Emelyanov c454e6111d tcp-repair: Handle zero-length data put in rcv queue
When sending data into a tcp socket in repair state we should check
for the amount of data being 0 explicitly. Otherwise we'll have an skb
with seq == end_seq in rcv queue, but tcp doesn't expect this to happen
(in particular a warn_on in tcp_recvmsg shoots).

Eric Dumazet a4d7e485bc vmxnet3: must split too big fragments
vmxnet3 has a 16Kbytes limit per tx descriptor, that happened to work
as long as we provided PAGE_SIZE fragments.

Our stack can now build larger fragments, so we need to split them to
the 16kbytes boundary.

Tom Parkin 789336360e l2tp: fix oops in l2tp_eth_create() error path
When creating an L2TPv3 Ethernet session, if register_netdev() should fail for
any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the
32k-interface limit), the netdev is freed in the error path.  However, the
l2tp_eth_sess structure's dev pointer is left uncleared, and this results in
l2tp_eth_delete() then attempting to unregister the same netdev later in the
session teardown.  This results in an oops.

To avoid this, clear the session dev pointer in the error path.

because the corresponding bridge is not in D0, so that

 "This series is a second round of target fixes for v3.7-rc4 that have
  come into target-devel over the last days, and are important enough to
  be applied ASAP.

  All are being CC'ed to stable.  The most important two are:

   - target: Re-add explict zeroing of INQUIRY bounce buffer memory to
     fix a regression for handling zero-length payloads, a bug that went
     during v3.7-rc1, and hit >= v3.6.3 stable.  (nab + paolo)

   - iscsi-target: Fix a long-standing missed R2T wakeup race in TX
     thread processing when using a single queue slot.  (Roland)

  Thanks to Roland & PureStorage team for helping to track down this
  long standing race with iscsi-target single queue slot operation.

  Also, the tcm_fc(FCoE) regression bug that was observed recently with
  -rc2 code has also been resolved with the cancel_delayed_work() return
  bugfix (commit c0158ca64da5: "workqueue: cancel_delayed_work() should
  return %false if work item is idle") now in -rc3.  Thanks again to Yi
  Zou, MDR, Robert Love @ Intel for helping to track this down."

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target: Fix incorrect usage of nested IRQ spinlocks in ABORT_TASK path
  iscsi-target: Fix missed wakeup race in TX thread
  target: Avoid integer overflow in se_dev_align_max_sectors()
  target: Don't return success from module_init() if setup fails

                          - device_lock(dev)	<--- deadlock here


If we do not do device_lock in pci_walk_bus, we can avoid deadlock.
Device_lock in pci_walk_bus is introduced in commit:
d71374dafb, corresponding email thread
is: https://lkml.org/lkml/2006/5/26/38.  The patch author Zhang Yanmin
said device_lock is added to pci_walk_bus because:

  Some error handling functions call pci_walk_bus. For example, PCIe
  aer. Here we lock the device, so the driver wouldn't detach from the
  device, as the cb might call driver's callback function.

So I fixed the deadlock as follows:

- remove device_lock from pci_walk_bus
- add device_lock into callback if callback will call driver's callback

I checked pci_walk_bus users one by one, and found only PCIe aer needs
device lock.

David Howells e7aa51b2e5 FRV: Fix the new-style kernel_thread() stuff
The kernel_thread() changes for FRV don't work, and FRV fails to boot,
starting with:

	commit 02ce496f15
	Author: Al Viro <viro@zeniv.linux.org.uk>
	Date:   Tue Sep 18 22:18:51 2012 -0400
	Subject: frv: split ret_from_fork, simplify kernel_thread() a lot

The problem is that the userspace registers are completely cleared when a
kernel thread is created and all subsequent user threads are then copied from
that.  Unfortunately, however, the TBR and PSR registers are restored from the
pt_regs and the values they should be set to are clobbered by the memset.

Instead, copy across the old user registers as normal, and then merely alter
GR8 and GR9 in it if we're going to execute a kernel thread.

David Howells 1ee6f5669a FRV: Fix the preemption handling
Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is
incorrectly loaded into the threadinfo flags rather than the threadinfo
preemption count.

Unfortunately, the code cannot be simply converted to use
preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to
cut down on the cost of actually disabling interrupts and thus
local_irq_enable() doesn't actually enable interrupts.

Wolfram Sang 82fa63bd6b i2c: mxs: remove broken PIOQUEUE support
This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
only PIOQUEUE was supported and it had issues, then DMA support was added
this cycle. The original intention was to keep PIOQUEUE since it has
less overhead what is nice for small transfers. However, runtime
switching between PIOQEUE and DMA depending on the transfer size never
worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
(polling at places where interrupts failed to work) and the
implementation also imposed a size limit for transfers, it is best to
remove the support, so users don't fall over its limitations. It also
makes the driver a lot cleaner and more robust. If somebody really wants
less overhead, plain PIO mode could still be implemented with the
addidtional advantage that this mode is also available on MX23, too.

Dave Airlie 3916e1d71b drm/udl: fix stride issues scanning out stride != width*bpp
When buffer sharing with the i915 and using a 1680x1050 monitor,
the i915 gives is a 6912 buffer for the 6720 width, the code doesn't
render this properly as it uses one value to set the base address for
reading from the vmap and for where to start on the device.

This fixes it by calculating the values correctly for the device and
for the pixmap. No idea how I haven't seen this before now.

All useful parts of the gpio-fan DT support rely on CONFIG_OF_GPIO

Jesper Dangaard Brouer 8f363b77ee net: fix divide by zero in tcp algorithm illinois
Reading TCP stats when using TCP Illinois congestion control algorithm
can cause a divide by zero kernel oops.

The division by zero occur in tcp_illinois_info() at:
 do_div(t, ca->cnt_rtt);
where ca->cnt_rtt can become zero (when rtt_reset is called)

Steps to Reproduce:
 1. Register tcp_illinois:
     # sysctl -w net.ipv4.tcp_congestion_control=illinois
 2. Monitor internal TCP information via command "ss -i"
     # watch -d ss -i
 3. Establish new TCP conn to machine

Either it fails at the initial conn, or else it needs to wait
for a loss or a reset.

This is only related to reading stats.  The function avg_delay() also
performs the same divide, but is guarded with a (ca->cnt_rtt > 0) at its
calling point in update_params().  Thus, simply fix tcp_illinois_info().

Function tcp_illinois_info() / get_info() is called without
socket lock.  Thus, eliminate any race condition on ca->cnt_rtt
by using a local stack variable.  Simply reuse info.tcpv_rttcnt,
as its already set to ca->cnt_rtt.
Function avg_delay() is not affected by this race condition, as
its called with the socket lock.
