SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
for a few platforms:
- Andres Färber adds initial support for the Actions Semi S500 (a.k.a.
'owl') platform, a close relative of the S900 platform he adds for arm64.
- in mach-omap2, we remove more legacy code
- Rockchips gains support for the RV1108 SoC designed for camera
applications.
- For Atmel, we gain support for MMU-less SoCs (SAME70/V71/S70/V70)
- Minor updates for other platforms, including davinci, s3c64xx,
prima2, stm32, broadcom nsp, amlogic, pxa, imx and renesas

Pull ACPI updates from Rafael Wysocki:
"These mostly update the ACPICA code in the kernel to upstream revision
20170531 which covers all of the new material from ACPI 6.2, including
new tables (WSMT, HMAT, PPTT), new subtables and definition changes
for some existing tables (BGRT, HEST, SRAT, TPM2, PCCT), new resource
descriptor macros for pin control, support for new predefined methods
(_LSI, _LSR, _LSW, _HMA), fixes and cleanups.
On top of that, an additional ACPICA change from Kees (which also is
upstream already) switches all of the definitions of function pointer
structures in ACPICA to use designated initializers so as to make the
structure layout randomization GCC plugin work with it.
The rest is a few fixes and cleanups in the EC driver, an xpower PMIC
driver update, a new backlight blacklist entry, and update of the
tables configfs interface and a messages formatting cleanup.
Specifics:
- Update the ACPICA code in the kernel to upstream revision revision
20170531 (which covers all of the new material from ACPI 6.2)
including:
* Support for the PinFunction(), PinConfig(), PinGroup(),
PinGroupFunction(), and PinGroupConfig() resource descriptors
(Mika Westerberg).
* Support for new subtables in HEST and SRAT, new notify value for
HEST, header support for TPM2 table changes, and BGRT Status
field update (Bob Moore).
* Support for new PCCT subtables (David Box).
* Support for _LSI, _LSR, _LSW, and _HMA as predefined methods
(Erik Schmauss).
* Support for the new WSMT, HMAT, and PPTT tables (Lv Zheng).
* New UUID values for Processor Properties (Bob Moore).
* New notify values for memory attributes and graceful shutdown
(Bob Moore).
* Fix related to the PCAT_COMPAT MADT flag (Janosch Hildebrand).
* Resource to AML conversion fix for resources containing GPIOs
(Mika Westerberg).
* Disassembler-related updates (Bob Moore, David Box, Erik
Schmauss).
* Assorted fixes and cleanups (Bob Moore, Erik Schmauss, Lv Zheng,
Cao Jin).
- Modify ACPICA to always use designated initializers for function
pointer structures to make the structure layout randomization GCC
plugin work with it (Kees Cook).
- Update the tables configfs interface to unload SSDTs on configfs
entry removal (Jan Kiszka).
- Add support for the GPI1 regulator to the xpower PMIC Operation
Region handler (Hans de Goede).
- Fix ACPI EC issues related to conflicting EC definitions in the
ECDT and in the ACPI namespace (Lv Zheng, Carlo Caione, Chris
Chiu).
- Fix an interrupt storm issue in the EC driver and make its debug
output work with dynamic debug as expected (Lv Zheng).
- Add ACPI backlight quirk for Dell Precision 7510 (Shih-Yuan Lee).
- Fix whitespace in pr_fmt() to align log entries properly in some
places in the ACPI subsystem (Vincent Legoll)"

- Rework suspend-to-idle to allow it to take wakeup events signaled
by the EC into account on ACPI-based platforms in order to properly
support power button wakeup from suspend-to-idle on recent Dell
laptops (Rafael Wysocki).
That includes the core suspend-to-idle code rework, support for
the Low Power S0 _DSM interface, and support for the ACPI INT0002
Virtual GPIO device from Hans de Goede (required for USB keyboard
wakeup from suspend-to-idle to work on some machines).
- Stop trying to export the current CPU frequency via /proc/cpuinfo
on x86 as that is inaccurate and confusing (Len Brown).
- Rework the way in which the current CPU frequency is exported by
the kernel (over the cpufreq sysfs interface) on x86 systems with
the APERF and MPERF registers by always using values read from
these registers, when available, to compute the current frequency
regardless of which cpufreq driver is in use (Len Brown).
- Rework the PCI/ACPI device wakeup infrastructure to remove the
questionable and artificial distinction between "devices that
can wake up the system from sleep states" and "devices that can
generate wakeup signals in the working state" from it, which
allows the code to be simplified quite a bit (Rafael Wysocki).
- Fix the wakeup IRQ framework by making it use SRCU instead of
RCU which doesn't allow sleeping in the read-side critical
sections, but which in turn is expected to be allowed by the
IRQ bus locking infrastructure (Thomas Gleixner).
- Modify some computations in the intel_pstate driver to avoid
rounding errors resulting from them (Srinivas Pandruvada).
- Reduce the overhead of the intel_pstate driver in the HWP
(hardware-managed P-states) mode and when the "performance"
P-state selection algorithm is in use by making it avoid
registering scheduler callbacks in those cases (Len Brown).
- Rework the energy_performance_preference sysfs knob in
intel_pstate by changing the values that correspond to
different symbolic hint names used by it (Len Brown).
- Make it possible to use more than one cpuidle driver at the same
time on ARM (Daniel Lezcano).
- Make it possible to prevent the cpuidle menu governor from using
the 0 state by disabling it via sysfs (Nicholas Piggin).
- Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1
on AMD systems (Yazen Ghannam).
- Make the CPPC cpufreq driver take the lowest nonlinear performance
information into account (Prashanth Prakash).
- Add support for hi3660 to the cpufreq-dt driver, fix the
imx6q driver and clean up the sfi, exynos5440 and intel_pstate
drivers (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila,
Rafael Wysocki, Tao Wang).
- Fix a few minor issues in the generic power domains (genpd)
framework and clean it up somewhat (Krzysztof Kozlowski,
Mikko Perttunen, Viresh Kumar).
- Fix a couple of minor issues in the operating performance points
(OPP) framework and clean it up somewhat (Viresh Kumar).
- Fix a CONFIG dependency in the hibernation core and clean it up
slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
- Add rk3228 support to the rockchip-io adaptive voltage scaling
(AVS) driver (David Wu).
- Fix an incorrect bit shift operation in the RAPL power capping
driver (Adam Lessnau).
- Add support for the EPP field in the HWP (hardware managed
P-states) control register, HWP.EPP, to the x86_energy_perf_policy
tool and update msr-index.h with HWP.EPP values (Len Brown).
- Fix some minor issues in the turbostat tool (Len Brown).
- Add support for AMD family 0x17 CPUs to the cpupower tool and fix
a minor issue in it (Sherry Hurwitz).
- Assorted cleanups, mostly related to the constification of some
data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
Kozlowski).

There's only one big change in this release but it's a very big change,
Geert Uytterhoeven has implemented support for SPI slave mode. This
feature has been on the cards since the subsystem was originally merged
back in the mists of time so it's great that Geert stepped up and
finally implemented it.
- SPI slave support, together with wholesale renaming of SPI
controllers from master to controller which went surprisingly
smoothly. This is already used with Renesas SoCs and support is in
the works for i.MX too.
- New drivers for Meson SPICC and ST STM32

This patch adds RTM_GETROUTE doit handler for mpls routes.
Input:
RTA_DST - input label
RTA_NEWDST - labels in packet for multipath selection
By default the getroute handler returns matched
nexthop label, via and oif
With RTM_F_FIB_MATCH flag, full matched route is
returned.
example (with patched iproute2):
$ip -f mpls route show

Elena Reshetova says:
====================
v2 ipv4/ipv6 refcount conversions
Changes in v2:
* rebase on top of net-next
* currently by default refcount_t = atomic_t (*) and uses all
atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled.
This is a compromise for the systems that are critical on
performance (such as net) and cannot accept even slight delay
on the refcounter operations.
This series, for ipv4/ipv6 network components, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
The patches are fully independent and can be cherry-picked separately.
In order to try with refcount functionality enabled in run-time,
CONFIG_REFCOUNT_FULL must be enabled.
NOTE: automatic kernel builder for some reason doesn't like all my
network branches and regularly times out the builds on these branches.
Suggestion for "waiting a day for a good coverage" doesn't work, as
we have seen with generic network conversions. So please wait for the
full report from kernel test rebot before merging further up.
This has been compile-tested in 116 configs, but 71 timed out (including
all s390-related configs again). I am trying to see if they can fix
build coverage for me in meanwhile.
* The respective change is currently merged into -next as
"locking/refcount: Create unchecked atomic_t implementation".

Here's the large set of staging and iio driver patches for 4.13-rc1.
After over 500 patches, we removed about 200 more lines of code than we
added, not great, but we added some new IIO drivers for unsupported
hardware, so it's an overall win.
Also here are lots of small fixes, and some tty core api additions (with
the tty maintainer's ack) for the speakup drivers, those are finally
getting some much needed cleanups and are looking much better now than
before. Full details in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

Here is the big patchset of USB and PHY driver updates for 4.13-rc1.
On the PHY side, they decided to move files around to "make things
easier" in their tree. Hopefully that wasn't a mistake, but in
linux-next testing, we haven't had any reported problems.
There's the usual set of gadget and xhci and musb updates in here as
well, along with a number of smaller updates for a raft of different USB
drivers. Full details in the shortlog, nothing really major.
All of these have been in linux-next for a while with no reported
issues.
