Fairly small update, but there are some interesting new features.

Common: Optional support for adding a small amount of polling on each HLT
instruction executed in the guest (or equivalent for other architectures).
This can improve latency up to 50% on some scenarios (e.g. O_DSYNC writes
or TCP_RR netperf tests).  This also has to be enabled manually for now,
but the plan is to auto-tune this in the future.

ARM/ARM64: the highlights are support for GICv3 emulation and dirty page
tracking

s390: several optimizations and bugfixes.  Also a first: a feature
exposed by KVM (UUID and long guest name in /proc/sysinfo) before
it is available in IBM's hypervisor! :)

MIPS: Bugfixes.

x86: Support for PML (page modification logging, a new feature in
Broadwell Xeons that speeds up dirty page tracking), nested virtualization
improvements (nested APICv---a nice optimization), usual round of emulation
fixes.  There is also a new option to reduce latency of the TSC deadline
timer in the guest; this needs to be tuned manually.

Some commits are common between this pull and Catalin's; I see you
have already included his tree.

ARM has other conflicts where functions are added in the same place
by 3.19-rc and 3.20 patches.  These are not large though, and entirely
within KVM.

rtlwifi:

* remove superfluous warning message which is not needed anymore

sound updates for 3.20-rc1

In this batch, you can find lots of cleanups through the whole

ACPI and power management updates for v3.20-rc1

 - Rework of the core ACPI resources parsing code to fix issues
   in it and make using resource offsets more convenient and
   consolidation of some resource-handing code in a couple of places
   that have grown analagous data structures and code to cover the
   the same gap in the core (Jiang Liu, Thomas Gleixner, Lv Zheng).

 - ACPI-based IOAPIC hotplug support on top of the resources handling
   rework (Jiang Liu, Yinghai Lu).

 - ACPICA update to upstream release 20150204 including an interrupt
   handling rework that allows drivers to install raw handlers for
   ACPI GPEs which then become entirely responsible for the given GPE
   and the ACPICA core code won't touch it (Lv Zheng, David E Box,
   Octavian Purdila).

 - ACPI EC driver rework to fix several concurrency issues and other
   problems related to events handling on top of the ACPICA's new
   support for raw GPE handlers (Lv Zheng).

 - New ACPI driver for AMD SoCs analogous to the LPSS (Low-Power
   Subsystem) driver for Intel chips (Ken Xue).

 - Two minor fixes of the ACPI LPSS driver (Heikki Krogerus,
   Jarkko Nikula).

 - Two new blacklist entries for machines (Samsung 730U3E/740U3E and
   510R) where the native backlight interface doesn't work correctly
   while the ACPI one does (Hans de Goede).

 - Rework of the ACPI processor driver's handling of idle states
   to make the code more straightforward and less bloated overall
   (Rafael J Wysocki).

 - Assorted minor fixes related to ACPI and SFI (Andreas Ruprecht,
   Andy Shevchenko, Hanjun Guo, Jan Beulich, Rafael J Wysocki,
   Yaowei Bai).

 - PCI core power management modification to avoid resuming (some)
   runtime-suspended devices during system suspend if they are in
   the right states already (Rafael J Wysocki).

 - New SFI-based cpufreq driver for Intel platforms using SFI
   (Srinidhi Kasagar).

 - cpufreq core fixes, cleanups and simplifications (Viresh Kumar,
   Doug Anderson, Wolfram Sang).

 - SkyLake CPU support and other updates for the intel_pstate driver
   (Kristen Carlson Accardi, Srinivas Pandruvada).

 - cpufreq-dt driver cleanup (Markus Elfring).

 - Init fix for the ARM big.LITTLE cpuidle driver (Sudeep Holla).

 - Generic power domains core code fixes and cleanups (Ulf Hansson).

 - Operating Performance Points (OPP) core code cleanups and kernel
   documentation update (Nishanth Menon).

 - New dabugfs interface to make the list of PM QoS constraints
   available to user space (Nishanth Menon).

 - New devfreq driver for Tegra Activity Monitor (Tomeu Vizoso).

 - New devfreq class (devfreq_event) to provide raw utilization data
   to devfreq governors (Chanwoo Choi).

 - Assorted minor fixes and cleanups related to power management
   (Andreas Ruprecht, Krzysztof Kozlowski, Rickard Strandqvist,
   Pavel Machek, Todd E Brandt, Wonhong Kwon).

 - turbostat updates (Len Brown) and cpupower Makefile improvement
   (Sriram Raghunathan).

media updates for v3.20-rc1

regulator: Updates for v3.20

This has not been a busy release for the regulator framework, though we
do have the first parts of some ongoing work from Bjorn Andersson to
allow us to support more complex modern systems with dynamic
configuration of regulators in suspend and idle states.

 - Support for device-specific properties on regulator nodes when using
   simplified DT parsing in the core from Krzysztof Kozlowski.
 - Restructuring of the load tracking code, intended to support future
   improvements in this area for more complex system designs.
 - New drivers for Maxim MAX77843 and Mediatek MT6397.
 - Lots of smaller fixes and improvements.

ASoC: Final updates for v3.20

A few more updates for v3.20 that have accumilated over the second half
of last week.  One new (relatively simple) driver for the Maxim
max98357a and some other driver specific fixes and enhancements.  I did
apply a few patches that haven't been in -next just now before sending
this, all fixes except for one simple device ID addition patch.

sound fixes for 3.19

Hopefully the final pull request for 3.19: this ended up with a
slightly higher volume than wished, but I put them all as they are
either stable or 3.19 regression fixes.

Most of commits are from ASoC, and have been stewed for a while in
linux-next.  The only change in the common code is the regression
fixes for ASoC AC97 stuff wrt device registrations.  The rest are
device-specific, mostly small fixes in various ASoC drivers and
ak411x on ice1724 boards.

ASoC: Fix for Intel firmware name

Another one liner that arrived after the earlier pull request.  There's
a trivial conflict with my -next branch, I'll send a pull request with
that resolution and some other new stuff before Monday.

ASoC: AC'97 fixes

These are rather too large for this late in the release cycle but
they're clear, well understood and have been tested to fix a regression
which was introduced for v3.19.  The details are all in Lars' changelog
and they've been cooking in -next for a while, to a large extent out
of conservatism about the size.
