John W. Linville says:

====================
Here is a batch of fixes intended for 3.7...

Amitkumar Karwar provides a couple of mwifiex fixes to correctly
report some reason codes for certain connection failures.  He also
provides a fix to cleanup after a scanning failure.  Bing Zhao rounds
that out with another mwifiex scanning fix.

Daniel Golle gives us a fix for a copy/paste error in rt2x00.

Felix Fietkau brings a couple of ath9k fixes related to suspend/resume,
and a couple of fixes to prevent memory leaks in ath9k and mac80211.

Ronald Wahl sends a carl9170 fix for a sleep in softirq context.

Thomas Pedersen reorders some code to prevent drv_get_tsf from being
called while holding a spinlock, now that it can sleep.

Finally, Wei Yongjun prevents a NULL pointer dereference in the
ath5k driver.

Please let me know if there are problems!

If there was a real fatal error, the corresponding h/w block will

Haicheng Li 0f79657984 pch_gbe: Fix build error by selecting all the possible dependencies.
Fengguang reported a kernel build failure as following:
drivers/built-in.o: In function `pch_gbe_ioctl':
pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write'
pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write'
pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write'
...

It's a regression by commit da1586461. The root cause is that
the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK
can not be set anyway, which finally causes ptp_pch and pch_gbe_main
build failures.

As David prefers to use *select* to fix such module co-dependency issues,
this patch explicitly selects all the possible dependencies of PCH_PTP.

Alexander Duyck c88887e090 ixgbe/ixgbevf: Limit maximum jumbo frame size to 9.5K to avoid Tx hangs
This change limits the PF/VF driver to 9.5K max jumbo frame size in order
prevent a possible Tx hang in the adapter when sending frames between
pools.

All of the parts in ixgbe support a maximum frame of 15.5K for standard
traffic, however with SR-IOV or DCB enabled they should be limiting the
MTU size to 9.5K.  Instead of adding extra checks which would have to
change the MTU when we go into or out of these modes it is preferred to
just use a standard 9.5K MTU limit for all modes so that this extra
overhead can be avoided.

Greg Rose 91e2b89b04 ixgbevf: Set the netdev number of Tx queues
The driver was not setting the number of real Tx queues in the net_device
structure.  This caused some serious issues such as Tx hangs and extremely
poor performance with some usages of the driver.

The issue is best observed by running:

iperf -c <host> -P <n>

Where n is greater than one.  The greater the value of n the more likely
the problem is to show up.

Linus Torvalds de390bba79 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS update from Ralf Baechle:
 "This is the MIPS update for 3.7.

  A fair chunk of them are platform updates to the Cavium Octeon SOC
  (which involves machine generated header files of considerable size),
  Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
  platforms.

  Support for the commercial MIPS simulator MIPSsim has been removed as
  MIPS Technologies is shifting away from this product and Qemu is
  offering various more powerful platforms.  The generic MIPS code can
  now also probe for no-execute / write-only TLB features implemented
  without the full SmartMIPS extension as permitted by the latest MIPS
  processor architecture.  Lots of small changes to generic code."

Eric Dumazet 2e71a6f808 net: gro: selective flush of packets
Current GRO can hold packets in gro_list for almost unlimited
time, in case napi->poll() handler consumes its budget over and over.

In this case, napi_complete()/napi_gro_flush() are not called.

Another problem is that gro_list is flushed in non friendly way :
We scan the list and complete packets in the reverse order.
(youngest packets first, oldest packets last)
This defeats priorities that sender could have cooked.

Since GRO currently only store TCP packets, we dont really notice the
bug because of retransmits, but this behavior can add unexpected
latencies, particularly on mice flows clamped by elephant flows.

This patch makes sure no packet can stay more than 1 ms in queue, and
only in stress situations.

It also complete packets in the right order to minimize latencies.

Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive

This issue has been around for years and a fix was sent 3.5 years ago, but
there was some debate as to whether it should instead be fixed as a PCI quirk.

Eric Dumazet acb600def2 net: remove skb recycling
Over time, skb recycling infrastructure got litle interest and
many bugs. Generic rx path skb allocation is now using page
fragments for efficient GRO / TCP coalescing, and recyling
a tx skb for rx path is not worth the pain.

Last identified bug is that fat skbs can be recycled
and it can endup using high order pages after few iterations.

With help from Maxime Bizon, who pointed out that commit
87151b8689 (net: allow pskb_expand_head() to get maximum tailroom)
introduced this regression for recycled skbs.

Instead of fixing this bug, lets remove skb recycling.

Drivers wanting really hot skbs should use build_skb() anyway,
to allocate/populate sk_buff right before netif_receive_skb()

Merge tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull ADM Xen support from Konrad Rzeszutek Wilk:

  Features:
   * Allow a Linux guest to boot as initial domain and as normal guests
     on Xen on ARM (specifically ARMv7 with virtualized extensions).  PV
     console, block and network frontend/backends are working.
  Bug-fixes:
   * Fix compile linux-next fallout.
   * Fix PVHVM bootup crashing.

  The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
  ARMv7 platforms.

  The goal in implementing this architecture is to exploit the hardware
  as much as possible.  That means use as little as possible of PV
  operations (so no PV MMU) - and use existing PV drivers for I/Os
  (network, block, console, etc).  This is similar to how PVHVM guests
  operate in X86 platform nowadays - except that on ARM there is no need
  for QEMU.  The end result is that we share a lot of the generic Xen
  drivers and infrastructure.

  Details on how to compile/boot/etc are available at this Wiki:

    http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions

  and this blog has links to a technical discussion/presentations on the
  overall architecture:
