Pull x86 fixes from Thomas Gleixner:
"A set of fixes and updates for x86:
- Address a swiotlb regression which was caused by the recent DMA
rework and made driver fail because dma_direct_supported() returned
false
- Fix a signedness bug in the APIC ID validation which caused invalid
APIC IDs to be detected as valid thereby bloating the CPU possible
space.
- Fix inconsisten config dependcy/select magic for the MFD_CS5535
driver.
- Fix a corruption of the physical address space bits when encryption
has reduced the address space and late cpuinfo updates overwrite
the reduced bit information with the original value.
- Dominiks syscall rework which consolidates the architecture
specific syscall functions so all syscalls can be wrapped with the
same macros. This allows to switch x86/64 to struct pt_regs based
syscalls. Extend the clearing of user space controlled registers in
the entry patch to the lower registers"

Pull clk updates from Stephen Boyd:
"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs
New Drivers:
- TI's Davinci family of SoCs
- Intel's Stratix10 SoC
- stm32mp157 SoC
- Allwinner H6 CCU
- Silicon Labs SI544 clock generator chip
- Renesas R-Car M3-N and V3H SoCs

Pull more power management updates from Rafael Wysocki:
"These include one big-ticket item which is the rework of the idle loop
in order to prevent CPUs from spending too much time in shallow idle
states. It reduces idle power on some systems by 10% or more and may
improve performance of workloads in which the idle loop overhead
matters. This has been in the works for several weeks and it has been
tested and reviewed quite thoroughly.
Also included are changes that finalize the cpufreq cleanup moving
frequency table validation from drivers to the core, a few fixes and
cleanups of cpufreq drivers, a cpuidle documentation update and a PM
QoS core update to mark the expected switch fall-throughs in it.
Specifics:
- Rework the idle loop in order to prevent CPUs from spending too
much time in shallow idle states by making it stop the scheduler
tick before putting the CPU into an idle state only if the idle
duration predicted by the idle governor is long enough.
That required the code to be reordered to invoke the idle governor
before stopping the tick, among other things (Rafael Wysocki,
Frederic Weisbecker, Arnd Bergmann).
- Add the missing description of the residency sysfs attribute to the
cpuidle documentation (Prashanth Prakash).
- Finalize the cpufreq cleanup moving frequency table validation from
drivers to the core (Viresh Kumar).
- Fix a clock leak regression in the armada-37xx cpufreq driver

- Fix the initialization of the CPU performance data structures for
shared policies in the CPPC cpufreq driver (Shunyong Yang).

clang-format is a tool to format C/C++/... code according to a set of
rules and heuristics. Like most tools, it is not perfect nor covers
every single case, but it is good enough to be helpful.
In particular, it is useful for quickly re-formatting blocks of code
automatically, for reviewing full files in order to spot coding style
mistakes, typos and possible improvements. It is also handy for sorting
``#includes``, for aligning variables and macros, for reflowing text and
other similar tasks. It also serves as a teaching tool/guide for
newcomers.
The tool itself has been already included in the repositories of popular
Linux distributions for a long time. The rules in this file are
intended for clang-format >= 4, which is easily available in most
distributions.
This commit adds the configuration file that contains the rules that the
tool uses to know how to format the code according to the kernel coding
style. This gives us several advantages:
* clang-format works out of the box with reasonable defaults;
avoiding that everyone has to re-do the configuration.
* Everyone agrees (eventually) on what is the most useful default
configuration for most of the kernel.
* If it becomes commonplace among kernel developers, clang-format
may feel compelled to support us better. They already recognize
the Linux kernel and its style in their documentation and in one
of the style sub-options.
Some of clang-format's features relevant for the kernel are:
* Uses clang's tooling support behind the scenes to parse and rewrite
the code. It is not based on ad-hoc regexps.
* Supports reasonably well the Linux kernel coding style.
* Fast enough to be used at the press of a key.
* There are already integrations (either built-in or third-party)
for many common editors used by kernel developers (e.g. vim,
emacs, Sublime, Atom...) that allow you to format an entire file
or, more usefully, just your selection.
* Able to parse unified diffs -- you can, for instance, reformat
only the lines changed by a git commit.
* Able to reflow text comments as well.
* Widely supported and used by hundreds of developers in highly
complex projects and organizations (e.g. the LLVM project itself,
Chromium, WebKit, Google, Mozilla...). Therefore, it will be
supported for a long time.

Pull MIPS updates from James Hogan:
"These are the main MIPS changes for 4.17. Rough overview:
(1) generic platform: Add support for Microsemi Ocelot SoCs
(2) crypto: Add CRC32 and CRC32C HW acceleration module
(3) Various cleanups and misc improvements
More detailed summary:
Miscellaneous:
- hang more efficiently on halt/powerdown/restart
- pm-cps: Block system suspend when a JTAG probe is present
- expand make help text for generic defconfigs
- refactor handling of legacy defconfigs
- determine the entry point from the ELF file header to fix microMIPS
for certain toolchains
- introduce isa-rev.h for MIPS_ISA_REV and use to simplify other code
Minor cleanups:
- DTS: boston/ci20: Unit name cleanups and correction
- kdump: Make the default for PHYSICAL_START always 64-bit
- constify gpio_led in Alchemy, AR7, and TXX9
- silence a couple of W=1 warnings
- remove duplicate includes
Platform support:
Generic platform:
- add support for Microsemi Ocelot
- dt-bindings: Add vendor prefix for Microsemi Corporation
- dt-bindings: Add bindings for Microsemi SoCs
- add ocelot SoC & PCB123 board DTS files
- MAINTAINERS: Add entry for Microsemi MIPS SoCs
- enable crc32-mips on r6 configs
ath79:
- fix AR724X_PLL_REG_PCIE_CONFIG offset
BCM47xx:
- firmware: Use mac_pton() for MAC address parsing
- add Luxul XAP1500/XWR1750 WiFi LEDs
- use standard reset button for Luxul XWR-1750
BMIPS:
- enable CONFIG_BRCMSTB_PM in bmips_stb_defconfig for build coverage
- add STB PM, wake-up timer, watchdog DT nodes
Octeon:
- drop '.' after newlines in printk calls
ralink:
- pci-mt7621: Enable PCIe on MT7688"
