6bdd2fd1ed Input: cap11xx - support for irq-active-high option
Some applications need to use the irq-active-high push-pull option.
This allows it be enabled in the device tree child node.

68da166491 Input: i8042 - disable active multiplexing by default
Active multiplexing is a nice feature as it allows several pointing devices
(such as touchpad and external mouse) use their native protocols at the
same time. Unfortunately many manufacturers do not implement the feature
properly even though they advertise it. The problematic implementations are
never fixed, since Windows by default does not use this mode, and move from
one BIOS/model of laptop to another. When active multiplexing is broken
turning it on usually results in touchpad, keyboard, or both unresponsive.

With PS/2 usage on decline (most of PS/2 devices in use nowadays are
internal laptop touchpads), I expect number of users who have laptops with
working MUX implementation, docking stations with external PS/2 ports, and
who are still using external PS/2 mice, to be rather small. Let's flip the
default to be OFF and allow activating it through i8042.nomux=0 kernel
option.  We'll also keep DMI table where we can record known good models.

Pull cgroup fixes from Tejun Heo:
 "This is quite late but these need to be backported anyway.

  This is the fix for a long-standing cpuset bug which existed from
  2009.  cpuset makes use of PF_SPREAD_{PAGE|SLAB} flags to modify the
  task's memory allocation behavior according to the settings of the
  cpuset it belongs to; unfortunately, when those flags have to be
  changed, cpuset did so directly even whlie the target task is running,
  which is obviously racy as task->flags may be modified by the task
  itself at any time.  This obscure bug manifested as corrupt
  PF_USED_MATH flag leading to a weird crash.

  The bug is fixed by moving the flag to task->atomic_flags.  The first
  two are prepatory ones to help defining atomic_flags accessors and the
  third one is the actual fix"

8369289864 ARM: SoC fixes for 3.17
Here's our last set of fixes for 3.17. Most of these are for TI platforms,
 fixing some noisy Kconfig issues, runtime clock and power issues on
 several platforms and NAND timings on DRA7.
 
 There are also a couple of bug fixes for i.MX, one for QCOM and a small
 fix to avoid section mismatch noise on PXA.
 
 Diffstat looks large, partially due to some tables being updated and
 thus touching many lines. The qcom gsbi change also restructures clock
 management a bit and thus touches a bunch of lines.
 
 All in all, a bit more changes than we'd like at this point, but nothing
 stands out as risky either so it seems like the right thing to send it
 up now instead of holding it to the merge window.

2ad654bc5e cpuset: PF_SPREAD_PAGE and PF_SPREAD_SLAB should be atomic flags
When we change cpuset.memory_spread_{page,slab}, cpuset will flip
PF_SPREAD_{PAGE,SLAB} bit of tsk->flags for each task in that cpuset.
This should be done using atomic bitops, but currently we don't,
which is broken.

Tetsuo reported a hard-to-reproduce kernel crash on RHEL6, which happened
when one thread tried to clear PF_USED_MATH while at the same time another
thread tried to flip PF_SPREAD_PAGE/PF_SPREAD_SLAB. They both operate on
the same task.

Here's the full report:
https://lkml.org/lkml/2014/9/19/230

To fix this, we make PF_SPREAD_PAGE and PF_SPREAD_SLAB atomic flags.

v4:
- updated mm/slab.c. (Fengguang Wu)
- updated Documentation.

Pull networking fixes from David Miller:

 1) If the user gives us a msg_namelen of 0, don't try to interpret
    anything pointed to by msg_name.  From Ani Sinha.

 2) Fix some bnx2i/bnx2fc randconfig compilation errors.

    The gist of the issue is that we firstly have drivers that span both
    SCSI and networking.  And at the top of that chain of dependencies
    we have things like SCSI_FC_ATTRS and SCSI_NETLINK which are
    selected.

    But since select is a sledgehammer and ignores dependencies,
    everything to select's SCSI_FC_ATTRS and/or SCSI_NETLINK has to also
    explicitly select their dependencies and so on and so forth.

    Generally speaking 'select' is supposed to only be used for child
    nodes, those which have no dependencies of their own.  And this
    whole chain of dependencies in the scsi layer violates that rather
    strongly.

    So just make SCSI_NETLINK depend upon it's dependencies, and so on
    and so forth for the things selecting it (either directly or
    indirectly).

    From Anish Bhatt and Randy Dunlap.

 3) Fix generation of blackhole routes in IPSEC, from Steffen Klassert.

 4) Actually notice netdev feature changes in rtl_open() code, from

 5) Fix divide by zero in bond enslaving, from Nikolay Aleksandrov.

 8) Don't call efx_{arch}_filter_sync_rx_mode before addr_list_lock is
    initialized in SFC driver, from Edward Cree.

 9) Fix missing DMA error checking in 3c59x, from Neal Horman.

10) Openvswitch doesn't emit OVS_FLOW_CMD_NEW notifications accidently,
    fix from Samuel Gauthier.

11) pch_gbe needs to select NET_PTP_CLASSIFY otherwise we can get a
    build error.

12) Fix macvlan regression wherein we stopped emitting
    broadcast/multicast frames over software devices.  From Nicolas

13) Fix infiniband bug due to unintended overflow of skb->cb[], from

    Tobias Klauser.

    from Eric Dumazet.

27180f7de7 spi: Fixes for v3.17
A few driver specific fixes for v3.17:
 
  - Fix davinci so that GPIO chip selects work with deferred probe of
    GPIOs (which could happen in production depending on kernel config)
    plus one incremental stylistic fix to that.
  - Several fixes for the newly introduced rockchip driver that came up
    in wider testing of the device.
  - A couple of small things in the sirf driver, one bug that would stop
    DMA transfers working and another update to follow the documented
    procedure in the datasheet.
  - Fix some memory leaks with devm_kzalloc() being used outside of the
    device bind path.

adff5962fd Input: introduce palmas-pwrbutton
Many palmas family of PMICs have support for interrupt based power button.
This allows the device to notify the processor of external push button
events over the shared palmas interrupt. However, this event is generated
only during a "press" operation. Software is supposed to poll(sigh!) for
detecting a release event.

The PMIC also supports ability to power off independent of the software
decisions when the button is pressed for a long duration if the PMIC is
appropriately configured on the platform.

Even though the function is similar to twl4030_pwrbutton, it is
substantially different in operation to belong to a new driver of it's own.

using LVDS channel 1 on an i.MX53 leads to following error:

imx-ldb 53fa8008.ldb: unable to set di0 parent clock to ldb_di1

This comes from imx_ldb_set_clock with mux = 0. Mux parameter must be "1" for
reparenting di1 clock to ldb_di1. The value of the mux param comes from device
tree port settings.

On i.MX5, the internal two-input-multiplexer is used. Due to hardware limitations,
only one port (port@[0,1]) can be used for each channel (lvds-channel@[0,1],
respectively)

Merge tag 'gpio-v3.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 - some documentation sync
 - resource leak in the bt8xx driver
 - again fix the way varargs are used to handle the optional flags on
   the gpiod_* accessors.  Now hopefully nailed the entire problem.

6e3be9bbea spi/rockchip: Mark DMA as optional
The Rockchip SPI controller works fine without DMA (aside from a few
warnings).  The DMA property even implies this, saying:

  DMA request names should include "tx" and "rx" if present.

Officially mark the properties as optional.

32797b3e06 video: fix composite video connector compatible string
The quite-recently-added analog-tv-connector bindings say that the
compatible string for composite video connector is
"composite-connector". That string is also used in the omap3-n900.dts
file. However, the connector driver uses "composite-video-connector", so
this has never worked.

While changing the driver's compatible string to "composite-connector"
would be safer, as published DT bindings should not be changed, I'd
rather fix the bindings in this case for two reasons:

* composite-connector is a bit too generic name, as it doesn't even hint
  at video.
* it's clear that this has never worked, which means no one has used
  those bindings, which should make it safe to change this.

19ed3eb975 ARM: SoC fixes for 3.17-rc
Here's the weekly batch of fixes from arm-soc.
 
 The delta is a largeish negative delta, due to revert of SMP support for Broadcom's
 STB SoC -- it was accidentally merged before some issues had been addressed, so they
 will make a new attempt for 3.18. I didn't see a need for a full revert of the whole
 platform due to this, we're keeping the rest enabled.
 
 The rest is mostly:
 
 * A handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
 * Some MTD/NAND fixes for OMAP
 * Minor DT fixes for shmobile
 * Warning fix for UP builds on vexpress/spc
 
 There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
 so it can boot. Drivers and the rest had landed for 3.17, and it's small
 and isolated so it made sense to pick up now even if it's not a bugfix.

5566401f2f stmmac: ptp: fix the reference clock
The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).

The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.

If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.

Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.
