git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"New and updated SoC support. Also included are some cleanups where
the platform maintainers hadn't separated cleanups from new developent
in separate branches.
Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might
start combining the cleanup and new-development branches more"

but a few across the board.
There are also some updates to MAINTAINERS here, in particular for
Broadcom platforms"

This adds a driver for the Dallas/Maxim DS1685-family of RTC chips. It
supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287,
DS17485/DS17487, and DS17885/DS17887 RTC chips. These chips are commonly
found in SGI O2 and SGI Octane systems. It was originally derived from a
driver patch submitted by Matthias Fuchs many years ago for use in
EPPC-405-UC modules, which also used these RTCs. In addition to the
time-keeping functions, this RTC also handles the shutdown mechanism of
the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these
systems.
Verified on both an SGI O2 and an SGI Octane.

Pull block driver changes from Jens Axboe:
"This contains:
- The 4k/partition fixes for brd from Boaz/Matthew.
- A few xen front/back block fixes from David Vrabel and Roger Pau
Monne.
- Floppy changes from Takashi, cleaning the device file creation.
- Switching libata to use the new blk-mq tagging policy, removing
code (and a suboptimal implementation) from libata. This will
throw you a merge conflict, since a bug in the original libata
tagging code was fixed since this code was branched. Trivial.
From Shaohua.
- Conversion of loop to blk-mq, from Ming Lei.
- Cleanup of the io_schedule() handling in bsg from Peter Zijlstra.
He claims it improves on unreadable code, which will cost him a
beer.
- Maintainer update or NDB, now handled by Markus Pargmann.
- NVMe:
- Optimization from me that avoids a kmalloc/kfree per IO for
smaller (<= 8KB) IO. This cuts about 1% of high IOPS CPU
overhead.

"Highlights incluse:
Features:
- Removing the forced serialisation of open()/close() calls in
NFSv4.x (x>0) makes for a significant performance improvement in
metadata intensive workloads.
- Full support for the pNFS "flexible files" layout type
- Further RPC/RDMA client improvements from Chuck
Bugfixes:
- Stable fix: NFSv4.1 backchannel calls blocking operations with !TASK_RUNNING
- Stable fix: pnfs_generic_pg_init_read/write can be called with lseg == NULL
- Stable fix: Fix an Oopsable condition when nsm_mon_unmon is called
as part of the namespace cleanup,
- Stable fix: Ensure we reference the inode for return-on-close in
delegreturn
- Use SO_REUSEPORT to ensure that NFSv3 TCP connections can rebind to
the same source address/port combination during a disconnect/
reconnect event. This is a requirement imposed by most NFSv3
server duplicate reply cache implementations.
Optimisations:
- Ask for no NFSv4.1 delegations on OPEN if using O_DIRECT

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull live patching infrastructure from Jiri Kosina:
"Let me provide a bit of history first, before describing what is in
this pile.
Originally, there was kSplice as a standalone project that implemented
stop_machine()-based patching for the linux kernel. This project got
later acquired, and the current owner is providing live patching as a
proprietary service, without any intentions to have their
implementation merged.
Then, due to rising user/customer demand, both Red Hat and SUSE
started working on their own implementation (not knowing about each
other), and announced first versions roughly at the same time [1] [2].
The principle difference between the two solutions is how they are
making sure that the patching is performed in a consistent way when it
comes to different execution threads with respect to the semantic
nature of the change that is being introduced.
In a nutshell, kPatch is issuing stop_machine(), then looking at
stacks of all existing processess, and if it decides that the system
is in a state that can be patched safely, it proceeds insterting code
redirection machinery to the patched functions.
On the other hand, kGraft provides a per-thread consistency during one
single pass of a process through the kernel and performs a lazy
contignuous migration of threads from "unpatched" universe to the
"patched" one at safe checkpoints.
If interested in a more detailed discussion about the consistency
models and its possible combinations, please see the thread that
evolved around [3].
It pretty quickly became obvious to the interested parties that it's
absolutely impractical in this case to have several isolated solutions
for one task to co-exist in the kernel. During a dedicated Live
Kernel Patching track at LPC in Dusseldorf, all the interested parties
sat together and came up with a joint aproach that would work for both
distro vendors. Steven Rostedt took notes [4] from this meeting.
And the foundation for that aproach is what's present in this pull
request.
It provides a basic infrastructure for function "live patching" (i.e.
code redirection), including API for kernel modules containing the
actual patches, and API/ABI for userspace to be able to operate on the
patches (look up what patches are applied, enable/disable them, etc).
It's relatively simple and minimalistic, as it's making use of
existing kernel infrastructure (namely ftrace) as much as possible.
It's also self-contained, in a sense that it doesn't hook itself in
any other kernel subsystem (it doesn't even touch any other code).
It's now implemented for x86 only as a reference architecture, but
support for powerpc, s390 and arm is already in the works (adding
arch-specific support basically boils down to teaching ftrace about
regs-saving).
Once this common infrastructure gets merged, both Red Hat and SUSE
have agreed to immediately start porting their current solutions on
top of this, abandoning their out-of-tree code. The plan basically is
that each patch will be marked by flag(s) that would indicate which
consistency model it is willing to use (again, the details have been
sketched out already in the thread at [3]).
Before this happens, the current codebase can be used to patch a large
group of secruity/stability problems the patches for which are not too
complex (in a sense that they don't introduce non-trivial change of
function's return value semantics, they don't change layout of data
structures, etc) -- this corresponds to LEAVE_FUNCTION &&
SWITCH_FUNCTION semantics described at [3].
This tree has been in linux-next since December.

[ The core code is introduced by the three commits authored by Seth
Jennings, which got a lot of changes incorporated during numerous
respins and reviews of the initial implementation. All the followup

public tree doesn't get rebased ]"

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management updates from Rafael Wysocki:
"We have a few new features this time, including a new SFI-based
cpufreq driver, a new devfreq driver for Tegra Activity Monitor, a new
devfreq class for providing its governors with raw utilization data
and a new ACPI driver for AMD SoCs.
Still, the majority of changes here are reworks of existing code to
make it more straightforward or to prepare it for implementing new
features on top of it. The primary example is the rework of ACPI
resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with
support for IOAPIC hotplug implemented on top of it, but there is
quite a number of changes of this kind in the cpufreq core, ACPICA,
ACPI EC driver, ACPI processor driver and the generic power domains
core code too.
The most active developer is Viresh Kumar with his cpufreq changes.
Specifics:
- 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).

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"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"

Conflicts:
drivers/net/vxlan.c
drivers/vhost/net.c
include/linux/if_vlan.h
net/core/dev.c
The net/core/dev.c conflict was the overlap of one commit marking an
existing function static whilst another was adding a new function.
In the include/linux/if_vlan.h case, the type used for a local
variable was changed in 'net', whereas the function got rewritten
to fix a stacked vlan bug in 'net-next'.
In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next'
overlapped with an endainness fix for VHOST 1.0 in 'net'.
In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter
in 'net-next' whereas in 'net' there was a bug fix to pass in the
correct network namespace pointer in calls to this function.

usb: patches for v3.20 merge window
Here's the big pull request for Gadgets and PHYs. It's
a total of 217 non-merge commits with pretty much everything
being touched.
The most important bits are a ton of new documentation for
almost all usb gadget functions, a new isp1760 UDC driver,
several improvements to the old net2280 UDC driver, and
some minor tracepoint improvements to dwc3.
Other than that, a big list of minor cleanups, smaller bugfixes
and new features all over the place.
