Some Broadcom boards have more GPIOs available. For example Linksys
E3200 home router is based on SoC id 0x5357, package 0x0A and uses GPIO
23 to reset internal USB WiFi (gpio23=wombo_reset).Signed-off-by: Rafał Miłecki

Pull MIPS updates from Ralf Baechle:
"The most notable new addition inside this pull request is the support
for MIPS's latest and greatest core called "inter/proAptiv". The
patch series describes this core as follows."The interAptiv is a power-efficient multi-core microprocessor
for use in system-on-chip (SoC) applications. The interAptiv combines
a multi-threading pipeline with a coherence manager to deliver improved
computational throughput and power efficiency. The interAptiv can
contain one to four MIPS32R3 interAptiv cores, system level
coherence manager with L2 cache, optional coherent I/O port,
and optional floating point unit."The platform specific patches touch all 3 Broadcom families. It adds
support for the new Broadcom/Netlogix XLP9xx Soc, building a common
BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count
and full gpio button/led descriptions for BCM47xx.The rest of the series are cleanups and bug fixes that are MIPS
generic and consist largely of changes that Imgtec/MIPS had published
in their linux-mti-3.10.git stable tree. Random other cleanups and

With this patch we prevent the irq from being fired when it is
registered. The Hardware fires an IRQ when input signal XOR polarity
AND gpio mask is 1. Now we are setting polarity to a vlaue so that is
is 0 when we register it.In addition we also set the irq mask register to 0 when the irq handler
is initialized, so all gpio irqs are masked and there will be no
unexpected irq.Signed-off-by: Hauke Mehrtens

Input GPIO changes can generate interrupts, but we need kind of ACK for
them by changing IRQ polarity. This is required to stop hardware from
keep generating interrupts and generate another one on the next GPIO
state change.
This code allows using GPIOs with standard interrupts and add for
example GPIO buttons support.Signed-off-by: Rafał Miłecki

Pull networking updates from David Miller:
1) The addition of nftables. No longer will we need protocol aware
firewall filtering modules, it can all live in userspace.At the core of nftables is a, for lack of a better term, virtual
machine that executes byte codes to inspect packet or metadata
(arriving interface index, etc.) and make verdict decisions.Besides support for loading packet contents and comparing them, the
interpreter supports lookups in various datastructures as
fundamental operations. For example sets are supports, and
therefore one could create a set of whitelist IP address entries
which have ACCEPT verdicts attached to them, and use the appropriate
byte codes to do such lookups.Since the interpreted code is composed in userspace, userspace can
do things like optimize things before giving it to the kernel.Another major improvement is the capability of atomically updating
portions of the ruleset. In the existing netfilter implementation,
one has to update the entire rule set in order to make a change and
this is very expensive.Userspace tools exist to create nftables rules using existing
netfilter rule sets, but both kernel implementations will need to
co-exist for quite some time as we transition from the old to the
new stuff.Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have
worked so hard on this.2) Daniel Borkmann and Hannes Frederic Sowa made several improvements
to our pseudo-random number generator, mostly used for things like
UDP port randomization and netfitler, amongst other things.In particular the taus88 generater is updated to taus113, and test
cases are added.3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet
and Yang Yingliang.4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin
Sujir.5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,
Neal Cardwell, and Yuchung Cheng.6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary
control message data, much like other socket option attributes.
From Francesco Fusco.7) Allow applications to specify a cap on the rate computed
automatically by the kernel for pacing flows, via a new
SO_MAX_PACING_RATE socket option. From Eric Dumazet.8) Make the initial autotuned send buffer sizing in TCP more closely
reflect actual needs, from Eric Dumazet.9) Currently early socket demux only happens for TCP sockets, but we
can do it for connected UDP sockets too. Implementation from Shawn
Bohrer.10) Refactor inet socket demux with the goal of improving hash demux
performance for listening sockets. With the main goals being able
to use RCU lookups on even request sockets, and eliminating the
listening lock contention. From Eric Dumazet.11) The bonding layer has many demuxes in it's fast path, and an RCU
conversion was started back in 3.11, several changes here extend the
RCU usage to even more locations. From Ding Tianhong and Wang
Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav
Falico.12) Allow stackability of segmentation offloads to, in particular, allow
segmentation offloading over tunnels. From Eric Dumazet.13) Significantly improve the handling of secret keys we input into the
various hash functions in the inet hashtables, TCP fast open, as
well as syncookies. From Hannes Frederic Sowa. The key fundamental
operation is "net_get_random_once()" which uses static keys.Hannes even extended this to ipv4/ipv6 fragmentation handling and
our generic flow dissector.14) The generic driver layer takes care now to set the driver data to
NULL on device removal, so it's no longer necessary for drivers to
explicitly set it to NULL any more. Many drivers have been cleaned
up in this way, from Jingoo Han.15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.
16) Improve CRC32 interfaces and generic SKB checksum iterators so that
SCTP's checksumming can more cleanly be handled. Also from Daniel
Borkmann.17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces
using the interface MTU value. This helps avoid PMTU attacks,
particularly on DNS servers. From Hannes Frederic Sowa.18) Use generic XPS for transmit queue steering rather than internal
(re-)implementation in virtio-net. From Jason Wang.* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1622 commits)

This PCI id is used by some BCM4313 cards without a sprom. I have seen
such a card on a router connected to some BCM63XX SoC via PCIe. There
are cards out there with the same PCI id and a BCM4311, which is a pre
ieee80211n chip only supporting ieee80211a, these are still not
supported by b43 and not detected by ssb.This devices was found by someone in this ticket:

This patch removes the bcma_core_pci_power_save() call from
the bcma_core_pci_{up,down}() functions as it tries to schedule
thus requiring to call them from non-atomic context. The function
bcma_core_pci_power_save() is now exported so the calling module
can explicitly use it in non-atomic context. This fixes the
'scheduling while atomic' issue reported by Tod Jackson and
