Pull power management updates from Rafael Wysocki:
"This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend and
hibernation, plus some driver changes depending on them and fixes for
issues in that area which have become quite apparent recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on
Surface Pro3.
On the cpufreq front we have fixes and cleanups in the core, some new
hardware support, driver updates and the removal of some unused code
from the CPU cooling thermal driver.
Apart from this, the Operating Performance Points (OPP) framework is
prepared to be used with power domains in the future and there is a
usual bunch of assorted fixes and cleanups.
Specifics:
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver PM
flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of genpd
(Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the ACPI
core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal and
clean up the governor management code in the cpufreq core (Rafael
Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh
Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri
Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id from
the PSCI driver and drop dependency on arm_big_little from the SCPI
cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,
Kyungsik Lee).
- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy
Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
Sergey Senozhatsky, gaurav jindal).
- Make it easier to disable PM via Kconfig (Mark Brown).
- Clean up the cpupower and intel_pstate_tracer utilities (Doug
Smythies, Laura Abbott)"

====================
pull-request: bpf-next 2018-01-26
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) A number of extensions to tcp-bpf, from Lawrence.
- direct R or R/W access to many tcp_sock fields via bpf_sock_ops
- passing up to 3 arguments to bpf_sock_ops functions
- tcp_sock field bpf_sock_ops_cb_flags for controlling callbacks
- optionally calling bpf_sock_ops program when RTO fires
- optionally calling bpf_sock_ops program when packet is retransmitted
- optionally calling bpf_sock_ops program when TCP state changes
- access to tclass and sk_txhash
- new selftest
2) div/mod exception handling, from Daniel.
One of the ugly leftovers from the early eBPF days is that div/mod
operations based on registers have a hard-coded src_reg == 0 test
in the interpreter as well as in JIT code generators that would
return from the BPF program with exit code 0. This was basically
adopted from cBPF interpreter for historical reasons.
There are multiple reasons why this is very suboptimal and prone
to bugs. To name one: the return code mapping for such abnormal
program exit of 0 does not always match with a suitable program
type's exit code mapping. For example, '0' in tc means action 'ok'
where the packet gets passed further up the stack, which is just
undesirable for such cases (e.g. when implementing policy) and
also does not match with other program types.
After considering _four_ different ways to address the problem,
we adapt the same behavior as on some major archs like ARMv8:
X div 0 results in 0, and X mod 0 results in X. aarch64 and
aarch32 ISA do not generate any traps or otherwise aborts
of program execution for unsigned divides.
Given the options, it seems the most suitable from
all of them, also since major archs have similar schemes in
place. Given this is all in the realm of undefined behavior,
we still have the option to adapt if deemed necessary.
3) sockmap sample refactoring, from John.
4) lpm map get_next_key fixes, from Yonghong.
5) test cleanups, from Alexei and Prashant.

The QS21/22 IBM Cell blades had a southbridge chip called Axon. This
could have DDR DIMMs attached to it, though they were not directly
usable as RAM, instead they could be used as some sort of buffer, if
applications were written specifically to use the block device
provided by the driver.
Although the driver supposedly had direct access support, it was
apparently never tested (see commit 91117a20245b ("axonram: Fix bug in
direct_access")).
These machines have not been available for over 5 years, and were
never widely in use. It seems highly unlikely anyone is using this
driver.
In general we're happy to leave old drivers in the tree, but because
DAX is involved this driver is caught up in the ongoing work in that
area, but none of the DAX folks are able to test it.
So remove the driver, if any one *is* using it, we'll be happy to put
it back.

As explained by Michal Marek at https://lkml.org/lkml/2011/8/31/189
silentoldconfig has become a misnomer. It has become an internal interface
so remove it from "make help" and Documentation/ to stop confusing people
using it as seen for instance at
https://chromium-review.googlesource.com/835632 Don't remove it from
kconfig/Makefile yet not to break any (other) tool using it.
On the other hand, correct and expand its description in the help of
the (internal) scripts/kconfig/conf.c

is optional because not all the SoCs need them but at least for Armada
7K/8K it is actually mandatory.
The binding documentation is updating accordingly.

Some systems need to set regulators to specific states when they enter
low power modes, especially around CPUs. There are many of these modes
depending on the particular runtime state.
Currently the regulator consumers are not granted permission to change
suspend state of regulator devices, the constraints are configured at
startup. In order to allow changes in a vlotage range, we need to add
new properties for voltage range and a flag to give permission to
change the suspend voltage and suspend on/off in suspend mode.

o Change process name in ps output: looks like, these days the process
is named kpktgend_<cpu>, rather than pktgen/<cpu>.
o Use pg_ctrl for start/stop as it can work well with pgset without
changes to $(PGDEV) variable.
o Clarify a bit needed $(PGDEV) definition for sample scripts and that
one needs to `source functions.sh`.
o Document how-to unset a behaviour flag, note about history expansion.

Introduce the "nfs_export" config, module and mount options.
The NFS export feature depends on the "index" feature and enables two
implicit overlayfs features: "index_all" and "verify_lower".
The "index_all" feature creates an index on copy up of every file and
directory. The "verify_lower" feature uses the full index to detect
overlay filesystems inconsistencies on lookup, like redirect from
multiple upper dirs to the same lower dir.
NFS export can be enabled for non-upper mount with no index. However,
because lower layer redirects cannot be verified with the index, enabling
NFS export support on an overlay with no upper layer requires turning off
redirect follow (e.g. "redirect_dir=nofollow").
The full index may incur some overhead on mount time, especially when
verifying that lower directory file handles are not stale.
NFS export support, full index and consistency verification will be
implemented by following patches.

Mention the maximum voltages of the CEC and HPD lines. Since in the example
these lines are connected to a Raspberry Pi and the Rpi GPIO lines are 3.3V
it is a good idea to warn against directly connecting the HPD to the Raspberry
Pi's GPIO line.

Since commit 9b6192589be7 ("media: lirc: implement scancode sending"),
and commit de142c324106 ("media: lirc: implement reading scancode")
the lirc features ioctl for raw IR devices advertises two modes for
sending and receiving.
The lirc daemon now fails to detect a raw IR device, both for transmit
and receive.
To fix this, do not advertise the scancode mode in the lirc features
for raw IR devices (however do keep it for scancode devices). The mode
can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8
(DAX2) processor chips, and has direct access to the CPU's L3 caches
as well as physical memory. It can perform several operations on data
streams with various input and output formats. This driver provides a
transport mechanism and has limited knowledge of the various opcodes
and data formats. A user space library provides high level services
and translates these into low level commands which are then passed
into the driver and subsequently the hypervisor and the coprocessor.
The library is the recommended way for applications to use the
coprocessor, and the driver interface is not intended for general use.

Pull "Few omap interconnect dts fixes for v4.16 merge window" from
Tony Lindgren:
Now that we have the dts clocks for the clkctrl clock and the
interconnect binding, we need to update the existing ti-sysc
users according to the binding to make it usable for drivers.
Apologies for not being able to send this earlier but it took
me few revisions to get the smartreflex changes right and
tested with yet to be posted patches to make smartreflex probe
with dts and I wanted to have it sit in next for a while to make
sure we're not introducing regressions for legacy platform data
based booting.
Note that this is based on a merge with commit 20a2742e5784
("dt-bindings: ti-sysc: Update binding for timers and capabilities")
to avoid a merge conflict with the binding changes.
