John W. Linville says:

====================
Please pull this batch of updates intended for 3.16...

For the mac80211 bits, Johannes says:

"Here I just have Heikki's rfkill GPIO cleanups.

The ARM/tegra patch is OK with the maintainer (Stephen). Let me know of
any problems."

and;

"We have a whole bunch of work on CSA by Andrei, Luca and Michal, but
unfortunately it doesn't seem quite complete yet so it's still disabled.
There's some TDLS work from Arik, and the rest is mostly minor fixes and
cleanups."

For the NFC bits, Samuel says:

"This is the NFC pull request for 3.16. We have:

- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
  thus relies on the HCI stack. This submission provides support for tag
  redaer/writer mode (including Type 5) and device tree bindings.

- PM runtime support and a bunch of bug fixes for TI's trf7970a.

- Device tree support for NXP's pn544. Legacy platform data support is
  obviously kept intact.

- NFC Tag type 4B support to the NFC Digital stack.

- SOCK_RAW type support to the raw NFC socket, and allow NCI
  sniffing from that. This can be extended to report HCI frames and also
  proprietarry ones like e.g. the pn533 ones."

For the iwlwifi bits, Emmanuel says:

"Eran continues to work on new devices, Eyal is still digging in
the rate control stuff, and Johannes added new functionality to the
debug system we have in place now along with a few cleanups he made
on the way.  That's pretty much it."

and;

"Avri continues to work on the power code and Eran is improving the
NVM handling as a preparations for new devices on which he works
with Liad. Luca cleans up a bit the code while working on CSA. I have
the regular BT Coex stuff and a small lockdep fix. Johannes has his
regular amount of clean ups and improvements, the main one is the
ability to leave 2 chains open to improve diversity and hence the
throughput in high attenuation scenarios."

and;

"The regular amount of housekeeping here. I merged iwlwifi-fixes.git to
be able to add the patch you didn't want in wireless.git at that stage
of the -rc cycle.  Luca has a few preparations for CSA implementation
and also what seems to be a bugfix for P2P but hasn't caused issues
we could notice."

For the Atheros bits, Kalle says:

"For ath10k Michal did various small fixes on how we handle
hardware/firmware problems and he also fixed two memory leaks."

Also included are a couple of pulls from the wireless tree to
avoid/resolve merge issues...

David S. Miller 54e5c4def0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/bonding/bond_alb.c
	drivers/net/ethernet/altera/altera_msgdma.c
	drivers/net/ethernet/altera/altera_sgdma.c
	net/ipv6/xfrm6_output.c

Several cases of overlapping changes.

The xfrm6_output.c has a bug fix which overlaps the renaming
of skb->local_df to skb->ignore_df.

In the Altera TSE driver cases, the register access cleanups
in net-next overlapped with bug fixes done in net.

Similarly a bug fix to send ALB packets in the bonding driver using
the right source address overlaps with cleanups in net-next.

Linus Torvalds 5fa6a683c0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
 "It looks like a sizeble collection but this is nearly 3 weeks of bug
  fixing while you were away.

   1) Fix crashes over IPSEC tunnels with NAT, the latter can reroute
      the packet through a non-IPSEC protected path and the code has to
      be able to handle SKBs attached to routes lacking an attached xfrm
      state.  From Steffen Klassert.

   2) Fix OOPSs in ipv4 and ipv6 ipsec layers for unsupported
      sub-protocols, also from Steffen Klassert.

   3) Set local_df on fragmented netfilter skbs otherwise we won't be
      able to forward successfully, from Florian Westphal.

   4) cdc_mbim ipv6 neighbour code does __vlan_find_dev_deep without
      holding RCU lock, from Bjorn Mork.

   5) local_df test in ip_may_fragment is inverted, from Florian
      Westphal.

   6) jme driver doesn't check for DMA mapping failures, from Neil
      Horman.

   7) qlogic driver doesn't calculate number of TX queues properly, from
      Shahed Shaikh.

   8) fib_info_cnt can drift irreversibly positive if we fail to
      allocate the fi->fib_metrics array, from Sergey Popovich.

   9) Fix use after free in ip6_route_me_harder(), also from Sergey
      Popovich.

  10) When SYSCTL is disabled, we don't handle local_port_range and
      ping_group_range defaults properly at all, from Cong Wang.

  11) Unaccelerated VLAN tagged frames improperly handled by cdc_mbim
      driver, fix from Bjorn Mork.

  12) cassini driver needs nested lock annotations for TX locking, from
      Emil Goode.

  13) On init error ipv6 VTI driver can unregister pernet ops twice,
      oops.  Fix from Mahtias Krause.

  14) If macvlan device is down, don't propagate IFF_ALLMULTI changes,
      from Peter Christensen.

  15) Missing NULL pointer check while parsing netlink config options in
      ip6_tnl_validate().  From Susant Sahani.

  16) Fix handling of neighbour entries during ipv6 router reachability
      probing, from Duan Jiong.

  17) x86 and s390 JIT address randomization has some address
      calculation bugs leading to crashes, from Alexei Starovoitov and
      Heiko Carstens.

  18) Clear up those uglies with nop patching and net_get_random_once(),
      from Hannes Frederic Sowa.

  19) Option length miscalculated in ip6_append_data(), fix also from
      Hannes Frederic Sowa.

  20) A while ago we fixed a race during device unregistry when a
      namespace went down, turns out there is a second place that needs
      similar protection.  From Cong Wang.

  21) In the new Altera TSE driver multicast filtering isn't working,
      disable it and just use promisc mode until the cause is found.
      From Vince Bridgers.

  22) When we disable router enabling in ipv6 we have to flush the
      cached routes explicitly, from Duan Jiong.

  23) NBMA tunnels should not cache routes on the tunnel object because
      the key is variable, from Timo Teräs.

  24) With stacked devices GRO information in skb->cb[] can be not setup
      properly, make sure it is in all code paths.  From Eric Dumazet.

  25) Really fix stacked vlan locking, multiple levels of nesting with
      intervening non-vlan devices are possible.  From Vlad Yasevich.

  26) Fallback ipip tunnel device's mtu is not setup properly, from
      Steffen Klassert.

  27) The packet scheduler's tcindex filter can crash because we
      structure copy objects with list_head's inside, oops.  From Cong
      Wang.

  28) Fix CHECKSUM_COMPLETE handling for ipv6 GRE tunnels, from Eric
      Dumazet.

  29) In some configurations 'itag' in __mkroute_input() can end up
      being used uninitialized because of how fib_validate_source()
      works.  Fix it by explitly initializing itag to zero like all the
      other fib_validate_source() callers do, from Li RongQing"

Prior to commit 4266129964 ("[media] DocBook: Move all media docbook
stuff into its own directory") it was possible to build only a single
(or more) book(s) by calling, for example

    make htmldocs DOCBOOKS=80211.xml

This now fails:

    cp: target `.../Documentation/DocBook//media_api' is not a directory

Ignore errors from that copy to make this possible again.

Thomas Petazzoni 3be2a49e5c of: provide a binding for fixed link PHYs
Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link" using a special PHY node.

This patch adds:

 * A documentation for the fixed PHY Device Tree binding.

 * An of_phy_is_fixed_link() function that an Ethernet driver can call
   on its PHY phandle to find out whether it's a fixed link PHY or
   not. It should typically be used to know if
   of_phy_register_fixed_link() should be called.

 * An of_phy_register_fixed_link() function that instantiates the
   fixed PHY into the PHY subsystem, so that when the driver calls
   of_phy_connect(), the PHY device associated to the OF node will be
   found.

These two additional functions also support the old fixed-link Device
Tree binding used on PowerPC platforms, so that ultimately, the
network device drivers for those platforms could be converted to use
of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
of_phy_connect_fixed_link(), while keeping compatibility with their
respective Device Tree bindings.

Linus Torvalds 200d963bf4 ARM: SoC fixes for 3.15-rc
Seems like we've had more fixes than usual this release cycle, but
 there's nothing in particular that we're doing differently. Perhaps it's
 just one of those cycles where more people are finding more regressions
 (and/or that the latency of when people actually test what's been in
 the tree for a while is catching up so that we get the bug reports now).
 
 The bigger changes here are are for TI and Marvell platforms:
 * Timing changes for GPMC (generic localbus) on OMAP causing some largeish
   DTS deltas.
 * Fixes to window allocation on PCI for mvebu touching drivers/ stuff. Patches
   have acks from subsystem maintainers where needed.
 * A fix from Thomas for a botched DT conversion in drivers/edma.
 
 There's a handful of other fixes for the above platforms as well as sunxi,
 at91, i.MX. I also included a MAINTAINER update for Broadcom, and a trivial
 move of a binding doc.

The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces.  These were simple transformations from
netlink_capable to netlink_ns_capable.

The Altera driver conflict was simply code removal overlapping some

Hans de Goede 36189cc3cd Input: elantech - fix touchpad initialization on Gigabyte U2442
The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"

Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

pull request: wireless-next 2014-05-02

Please pull this batch of updates intended for the 3.16 stream...

For the mac80211 bits, Johannes says:

"In this round we have a large number of small features and
improvements from people too numerous to list here. The only really
bit thing is Michał and Luca's CSA work (including changing how
interface combination verification is done)."

For the Bluetooth bits, Gustavo says:

"Here goes some patches for the -next release. There is nothing
really special for this pull request, just a bunch of refactors,
fixes and clean ups."

For the ath10k/ath6kl bits, Kalle says:

"For ath6kl Kalle fixed a bunch of checkpatch warnings.

In ath10k we had more changes, major ones being:

* fix memory allocation failures after a firmware crash (Michal)

* some rework of DFS configuration to enable it correctly in all cases
  (Michal)

* add a new firmware crash option to make it possible to crash 10.1
  firmware for testing purposes (Marek P)

* fix RTS/CTS protection in certain cases (Marek K)

* fix wrong RSSI and rate reporting in some cases (Janusz)

* fix firmware stats reporting (Chun, Ben & Bartosz)"

For the iwlwifi bits, Emmanuel says:

"I have here a bunch of unrelated things. I disabled support for
-7.ucode which means that I can removed a lot of code. Eliad has
a brand new feature: we reduce the Tx power when the link allows -
this reduces our power consumption. The regular changes in power and
scan area. One interesting thing though is the patches from Johannes,
we have now GRO which allows to increase our throughput in TCP Rx. The
main advantage is that it reduces the number of TCP Acks - these TCP
Acks are completely useless when we are using A-MPDU since the first
packet of the A-MPDU generates a TCP Ack which is made obsolete by
the next packets."

Along with that, there are a variety of updates to b43, mwifiex,
rtl8180 and wil6210 drivers and a handful of other updates here
and there.

Please let me know if there are problems!

clockevent fixes for 3.15 from Daniel Lezcano:
 * Lorenzo Pieralizi fixed an issue with the arch_arm_timer where the
   C3STOP flag for all the arch can cause some trouble by setting the
   flag only if the power domain is not always on
 * Alexander Shiyan fixed a compilation by changing the init function
   to the right prototype

Thomas Gleixner cf7eb97911 ARM: common: edma: Fix xbar mapping
This is another great example of trainwreck engineering:

commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support)
added support for using EDMA on peripherals which have no direct EDMA
event mapping.

The code compiles and does not explode in your face, but that's it.

1) Reading an u16 array from an u32 device tree array simply does not
   work. Even if the function is named "edma_of_read_u32_to_s16_array".

   It merily calls of_property_read_u16_array. So the resulting 16bit
   array will have every other entry = 0.

2) The DT entry for the xbar registers related to xbar has length 0x10
   instead of the real length: 0xfd0 - 0xf90 = 0x40.

   Not a real problem as it does not cross a page boundary, but
   wrong nevertheless.

3) But none of this matters as the mapping never happens:

   After reading nonsense edma_of_read_u32_to_s16_array() invalidates
   the first array entry pair, so nobody can ever notice the
   braindamage by immediate explosion.

Seems the QA criteria for this code was solely not to explode when
someone adds edma-xbar-event-map entries to the DT. Goal achieved,
congratulations!

Not really helpful if someone wants to use edma on a device which
requires a xbar mapping.

Fix the issues by:

- annotating the device tree entry with "/bits/ 16" as documented in
  the of_property_read_u16_array kernel doc

- make the size of the xbar register mapping correct

- invalidating the end of the array and not the start

This convoluted mess wants to be completely rewritten as there is no
point to keep the xbar_chan array memory and the iomapping of the xbar
regs around forever. Marking the xbar mapped channels as used should
be done right there.

But that's a different issue and this patch is small enough to make it
work and allows a simple backport for stable.

Lorenzo Pieralisi 82a5619410 clocksource: arch_arm_timer: Fix age-old arch timer C3STOP detection issue
ARM arch timers are tightly coupled with the CPU logic and lose context
on platform implementing HW power management when cores are powered
down at run-time. Marking the arch timers as C3STOP regardless of power
management capabilities causes issues on platforms with no power management,
since in that case the arch timers cannot possibly enter states where the
timer loses context at runtime and therefore can always be used as a high
resolution clockevent device.

In order to fix the C3STOP issue in a way compliant with how real HW
works, this patch adds a boolean property to the arch timer bindings
to define if the arch timer is managed by an always-on power domain.

This power domain is present on all ARM platforms to date, and manages
HW that must not be turned off, whatever the state of other HW
components (eg power controller). On platforms with no power management
capabilities, it is the only power domain present, which encompasses
and manages power supply for all HW components in the system.

If the timer is powered by the always-on power domain, the always-on
property must be present in the bindings which means that the timer cannot
be shutdown at runtime, so it is not a C3STOP clockevent device.
If the timer binding does not contain the always-on property, the timer is
assumed to be power-gateable, hence it must be defined as a C3STOP
clockevent device.
