a0693bd0aa Revert "usb : Add sysfs files to control port power."
This reverts commit ca9c9d0c922e4f1dac80699ebab1269d6dbaff85.

Rafael wants more time to work on the user api to handle port power
issues, so let's just revert the sysfs changes for now.

Merge tag 'v3.6-rc7' into drm-intel-next-queued

Manual backmerge of -rc7 to resolve a silent conflict leading to
compile failure in drivers/gpu/drm/i915/intel_hdmi.c.

This is due to the bugfix in -rc7:

commit b98b60167279df3acac9422c3c9820d9ebbcf9fb
Author: Wang Xingchao <xingchao.wang@intel.com>
Date:   Thu Sep 13 07:43:22 2012 +0800

    drm/i915: HDMI - Clear Audio Enable bit for Hot Plug

Since this code moved around a lot in -next git put that snippet at
the wrong spot. I've tried to fix this by making the conflict explicit
by merging a version for next with:

commit 3cce574f0190dd149472059fb69267cf83d290f9
Author: Wang Xingchao <xingchao.wang@intel.com>
Date:   Thu Sep 13 11:19:00 2012 +0800

    drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally

But that failed to solve the entire problem. To avoid pushing out
further -nightly branch to our QA where this is broken, do the
backmerge and manually add the stuff git adds to -next from the patch
in -fixes.

Note that this doesn't show up in git's merge diff (and hence is also
not handled by git rerere), which adds to the reasons why I'd like to
fix this with a verbose backmerge. The git merge diff only shows a
bunch of trivial conflicts of the "code changed in lines next to each
another" kind.

c48cbba6fe hwmon: exynos4: move thermal sensor driver to driver/thermal directory
This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by
driver/thermal/thermal_sys.c.  The goal is to place it in thermal folder
and add necessary functions to use the in-kernel thermal interfaces.

0236141837 thermal: add generic cpufreq cooling implementation
This patchset introduces a new generic cooling device based on cpufreq
that can be used on non-ACPI platforms.  As a proof of concept, we have
drivers for the following platforms using this mechanism now:

 * Samsung Exynos (Exynos4 and Exynos5) in the current patchset.
 * Freescale i.MX (git://git.linaro.org/people/amitdanielk/linux.git imx6q_thermal)

There is a small change in cpufreq cooling registration APIs, so a minor
change is needed for Freescale platforms.

Brief Description:

1) The generic cooling devices code is placed inside driver/thermal/*
   as placing inside acpi folder will need un-necessary enabling of acpi
   code.  This code is architecture independent.

2) This patchset adds generic cpu cooling low level implementation
   through frequency clipping.  In future, other cpu related cooling
   devices may be added here.  An ACPI version of this already exists
   (drivers/acpi/processor_thermal.c) .But this will be useful for
   platforms like ARM using the generic thermal interface along with the
   generic cpu cooling devices.  The cooling device registration API's
   return cooling device pointers which can be easily binded with the
   thermal zone trip points.  The important APIs exposed are,

   a) struct thermal_cooling_device *cpufreq_cooling_register(
        struct cpumask *clip_cpus)
   b) void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev)

3) Samsung exynos platform thermal implementation is done using the
   generic cpu cooling APIs and the new trip type.  The temperature sensor
   driver present in the hwmon folder(registered as hwmon driver) is moved
   to thermal folder and registered as a thermal driver.

A simple data/control flow diagrams is shown below,

Core Linux thermal <----->  Exynos thermal interface <----- Temperature Sensor
          |                             |
         \|/                            |
  Cpufreq cooling device <---------------

TODO:
*Will send the DT enablement patches later after the driver is merged.

This patch:

Add support for generic cpu thermal cooling low level implementations
using frequency scaling up/down based on the registration parameters.
Different cpu related cooling devices can be registered by the user and
the binding of these cooling devices to the corresponding trip points can
be easily done as the registration APIs return the cooling device pointer.
The user of these APIs are responsible for passing clipping frequency .
The drivers can also register to recieve notification about any cooling
action called.

The print_cpu_stall_fast_no_hz() function attempts to print -1 when

to instead print ULONG_MAX, which is 4294967295 on 32-bit systems and

d40011f601 rcu: Control grace-period duration from sysfs
Although almost everyone is well-served by the defaults, some uses of RCU
benefit from shorter grace periods, while others benefit more from the
greater efficiency provided by longer grace periods.  Situations requiring
a large number of grace periods to elapse (and wireshark startup has
been called out as an example of this) are helped by lower-latency
grace periods.  Furthermore, in some embedded applications, people are
willing to accept a small degradation in update efficiency (due to there
being more of the shorter grace-period operations) in order to gain the
lower latency.

In contrast, those few systems with thousands of CPUs need longer grace
periods because the CPU overhead of a grace period rises roughly
linearly with the number of CPUs.  Such systems normally do not make
much use of facilities that require large numbers of grace periods to
elapse, so this is a good tradeoff.

Therefore, this commit allows the durations to be controlled from sysfs.
There are two sysfs parameters, one named "jiffies_till_first_fqs" that
specifies the delay in jiffies from the end of grace-period initialization
until the first attempt to force quiescent states, and the other named
"jiffies_till_next_fqs" that specifies the delay (again in jiffies)
between subsequent attempts to force quiescent states.  They both default
to three jiffies, which is compatible with the old hard-coded behavior.

At some future time, it may be possible to automatically increase the
grace-period length with the number of CPUs, but we do not yet have
sufficient data to do a good job.  Preliminary data indicates that we
should add an addiitonal jiffy to each of the delays for every 200 CPUs
in the system, but more experimentation is needed.  For now, the number
of systems with more than 1,000 CPUs is small enough that this can be
relegated to boot-time hand tuning.

7a84428af7 KVM: Add resampling irqfds for level triggered interrupts
To emulate level triggered interrupts, add a resample option to
KVM_IRQFD.  When specified, a new resamplefd is provided that notifies
the user when the irqchip has been resampled by the VM.  This may, for
instance, indicate an EOI.  Also in this mode, posting of an interrupt
through an irqfd only asserts the interrupt.  On resampling, the
interrupt is automatically de-asserted prior to user notification.
This enables level triggered interrupts to be posted and re-enabled
from vfio with no userspace intervention.

All resampling irqfds can make use of a single irq source ID, so we
reserve a new one for this interface.

Context conflicts in arch/arm/Kconfig and arch/arm/mach-dove/common.c.

The new device trees added to arch/arm/mach-kirkwood/Makefile.boot are
kept and dealt with in a separate changeset, since moving them out to
the new Makefile in this merge commit doesn't work well.

de46584675 ptp: clarify the clock_name sysfs attribute
There has been some confusion among PHC driver authors about the
intended purpose of the clock_name attribute. This patch expands the
documation in order to clarify how the clock_name field should be
understood.

3d98c21d06 ASoC: Updates for v3.7
Lots and lots of driver specific cleanups and enhancements but the only
 substantial framework feature this time round is the compressed API
 binding:
 
 - Addition of ASoC bindings for the compressed API, used by the mid-x86
   drivers.
 - Lots of cleanups and API refreshes for CODEC drivers and DaVinci.
 - Conversion of OMAP to dmaengine.
 - New machine driver for Wolfson Microelectronics Bells.
 - New CODEC driver for Wolfson Microelectronics WM0010.

5e953778a2 ipconfig: add nameserver IPs to kernel-parameter ip=
On small systems (e.g. embedded ones) IP addresses are often configured
by bootloaders and get assigned to kernel via parameter "ip=".  If set to
"ip=dhcp", even nameserver entries from DHCP daemons are handled. These
entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf.

To configure nameservers for networks without DHCP, this patch adds option
<dns0-ip> and <dns1-ip> to kernel-parameter 'ip='.

903234673f arm: add documentation describing Marvell families of SoC
As stated in the introduction of the document, the families of ARM
SoCs at Marvell are very complicated, and it is difficult for
newcomers to understand the organization of this SoC family and how it
relates to the Linux kernel support for those hardware platforms.

This document is only at RFC stage for now, it requires reviews and
comments from the Marvell maintainers, the PXA maintainers and the MMP
maintainers. For correctness of course, but also to add any other
information that would be useful. For example, one of the thing that
wasn't clear how to detail in the documentation is how the SoCs relate
to each other in terms of hardware IP blocks. For example, most of the
Kirkwood/Dove/Armada 370-XP/etc. hardware IPs (I2C, SPI, USB, SATA,
etc.) are identical, while the PXA and MMP families are completely
separate.
