Pull misc compat stuff updates from Al Viro:
"This part is basically untangling various compat stuff. Compat
syscalls moved to their native counterparts, getting rid of quite a
bit of double-copying and/or set_fs() uses. A lot of field-by-field
copyin/copyout killed off.
- kernel/compat.c is much closer to containing just the
copyin/copyout of compat structs. Not all compat syscalls are gone
from it yet, but it's getting there.
- ipc/compat_mq.c killed off completely.
- block/compat_ioctl.c cleaned up; floppy compat ioctls moved to
drivers/block/floppy.c where they belong. Yes, there are several
drivers that implement some of the same ioctls. Some are m68k and
one is 32bit-only pmac. drivers/block/floppy.c is the only one in
that bunch that can be built on biarch"

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"The new features of this release:
- Added TRACE_DEFINE_SIZEOF() which allows trace events that use
sizeof() it the TP_printk() to be converted to the actual size such
that trace-cmd and perf can parse them correctly.
- Some rework of the TRACE_DEFINE_ENUM() such that the above
TRACE_DEFINE_SIZEOF() could reuse the same code.
- Recording of tgid (Thread Group ID). This is similar to how task
COMMs are recorded (cached at sched_switch), where it is in a table
and used on output of the trace and trace_pipe files.
- Have ":mod:<module>" be cached when written into set_ftrace_filter.
Then the functions of the module will be traced at module load.
- Some random clean ups and small fixes"

Pull dma-mapping infrastructure from Christoph Hellwig:
"This is the first pull request for the new dma-mapping subsystem
In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls to
->mapping_error so that the dma_map_ops instances are more self
contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code
(Vladimir)
- various smaller cleanups (me)"

Pull pin control updates from Linus Walleij:
"This is the big bulk of pin control changes for the v4.13 series:
Core:
- The documentation is moved over to RST.
- We now have agreed bindings for enabling input and output buffers
without actually enabling input and/or output on a pin. We are
chiseling out some details of pin control electronics.
New drivers:
- ZTE ZX
- Renesas RZA1
- MIPS Ingenic JZ47xx: also switch over existing drivers in the tree
to use this pin controller and consolidate earlier spread out code.
- Microschip MCP23S08: this driver is migrated from the GPIO
subsystem and totally rewritten to use proper pin control. All
users are switched over.
New subdrivers:
- Renesas R8A7743 and R8A7745.
- Allwinner Sunxi A83T R_PIO.
- Marvell MVEBU Armada CP110 and AP806.
- Intel Cannon Lake PCH.
- Qualcomm IPQ8074.
Notable improvements:
- IRQ support on the Marvell MVEBU Armada 37xx.
- Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
- Rockchip driver now supports iomux-route switching for RK3228,
RK3328 and RK3399.
- Rockchip A10 and A20 are merged into a single driver.
- STM32 has improved GPIO support.
- Samsung Exynos drivers are split per ARMv7 and ARMv8.
- Marvell MVEBU is converted to use regmap for register access.
Maintenance:
- Several Renesas SH-PFC refactorings and updates.
- Serious code size cut for Mediatek MT7623.
- Misc janitorial and MAINTAINERS fixes"

Pull GCC plugin updates from Kees Cook:
"The big part is the randstruct plugin infrastructure.
This is the first of two expected pull requests for randstruct since
there are dependencies in other trees that would be easier to merge
once those have landed. Notably, the IPC allocation refactoring in
-mm, and many trivial merge conflicts across several trees when
applying the __randomize_layout annotation.
As a result, it seemed like I should send this now since it is
relatively self-contained, and once the rest of the trees have landed,
send the annotation patches. I'm expecting the final phase of
randstruct (automatic struct selection) will land for v4.14, but if
its other tree dependencies actually make it for v4.13, I can send
that merge request too.
Summary:

After commmit 692f66f26a4c19 ("crash: move crashkernel parsing and vmcore
related code under CONFIG_CRASH_CORE") the KEXEC_NOTE_BYTES macro is not
used anymore and for s390 we create the ELF header in the new kernel
anyway. Therefore remove the macro.

Pull ARM SoC 64-bit updates from Arnd Bergmann:
"Changes to platform code for 64-bit ARM platforms.
Andreas Färber adds two new platforms with initial code: Realtek
RTD1295 and Action Semi S900. Both are fairly similar chips, used
mainly in set-top-boxes, but with other possible applications, and
additional members in the respective product families that could be
added in the future. The code here is fairly minimal, as all the
interesting parts are in device drivers and dts files.
The Broadcom Vulcan platform gets dropped, as no products ever became
available, and Cavium integrated the platform under a new name.
Among some other defconfig changes, Timur Tabi enables a number of
options that are typically required for server platforms"

Pull ARM 64-bit DT updates from Arnd Bergmann:
"Device-tree updates for arm64 platforms. For the first time I can
remember, this is actually larger than the corresponding branch for
32-bit platforms overall, though that has more individual changes.
A significant portion this time is due to added machine support:
- Initial support for the Realtek RTD1295 SoC, along with the Zidoo
X9S set-top-box
- Initial support for Actions Semi S900 and the Bubblegum-96
single-board-cёmputer.
- Rockchips support for the rk3399-Firefly single-board-computer gets
added, this one stands out for being relatively fast, affordable
and well₋supported, compared to many boards that only fall into one
or two of the above categories.
- Mediatek gains support for the mt6797 mobile-phone SoC platform and
corresponding evaluation board.
- Amlogic board support gets added for the NanoPi K2 and S905x
LibreTech CC single-board computers and the R-Box Pro set-top-box
- Allwinner board support gets added for the OrangePi Win, Orangepi
Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers
and the SoPine system-on-module.
- Renesas board support for Salvator-XS and H3ULCB automotive
development systems.
- Socionext Uniphier board support for LD11-global and LD20-global,
whatever those may be.
- Broadcom adds support for the new Stingray communication processor
in its iProc family, along with two reference boards.
Other updates include:
- For the hisicon platform, support for Hi3660-Hikey960 gets extended
significantly.
- Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP"

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
"The big ticket items here are the rework of suspend-to-idle in order
to add proper support for power button wakeup from it on recent Dell
laptops and the rework of interfaces exporting the current CPU
frequency on x86.
In addition to that, support for a few new pieces of hardware is
added, the PCI/ACPI device wakeup infrastructure is simplified
significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
bus locking infrastructure.
Also, there are some functional improvements for intel_pstate, tools
updates and small fixes and cleanups all over.
Specifics:
- 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)"

Pull SMP hotplug updates from Thomas Gleixner:
"This update is primarily a cleanup of the CPU hotplug locking code.
The hotplug locking mechanism is an open coded RWSEM, which allows
recursive locking. The main problem with that is the recursive nature
as it evades the full lockdep coverage and hides potential deadlocks.
The rework replaces the open coded RWSEM with a percpu RWSEM and
establishes full lockdep coverage that way.
The bulk of the changes fix up recursive locking issues and address
the now fully reported potential deadlocks all over the place. Some of
these deadlocks have been observed in the RT tree, but on mainline the
probability was low enough to hide them away."

Pull x86 timers updates from Thomas Gleixner:
"This update contains:
- The solution for the TSC deadline timer borkage, which is caused by
a hardware problem in the TSC_ADJUST/TSC_DEADLINE_TIMER logic.
The problem is documented now and fixed with a microcode update, so
we can remove the workaround and just check for the microcode version.
If the microcode is not up to date, then the TSC deadline timer is
disabled. If the borkage is fixed by the proper microcode version,
then the deadline timer can be used. In both cases the restrictions
to the range of the TSC_ADJUST value, which were added as
workarounds, are removed.
- A few simple fixes and updates to the timer related x86 code"

Pull x86 PCI updates from Thomas Gleixner:
"This update provides the seperation of x86 PCI accessors from the
global PCI lock in the generic PCI config space accessors.
The reasons for this are:
- x86 has it's own PCI config lock for various reasons, so the
accessors have to lock two locks nested.
- The ECAM (mmconfig) access to the extended configuration space does
not require locking. The existing generic locking causes a massive
lock contention when accessing the extended config space of the
Uncore facility for performance monitoring.
The commit which switched the access to the primary config space over
to ECAM mode has been removed from the branch, so the primary config
space is still accessed with type1 accessors properly serialized by
the x86 internal locking.
Bjorn agreed on merging this through the x86 tree"

Pull irq updates from Thomas Gleixner:
"The irq department delivers:
- Expand the generic infrastructure handling the irq migration on CPU
hotplug and convert X86 over to it. (Thomas Gleixner)
Aside of consolidating code this is a preparatory change for:
- Finalizing the affinity management for multi-queue devices. The
main change here is to shut down interrupts which are affine to a
outgoing CPU and reenabling them when the CPU comes online again.
That avoids moving interrupts pointlessly around and breaking and
reestablishing affinities for no value. (Christoph Hellwig)
Note: This contains also the BLOCK-MQ and NVME changes which depend
on the rework of the irq core infrastructure. Jens acked them and
agreed that they should go with the irq changes.
- Consolidation of irq domain code (Marc Zyngier)
- State tracking consolidation in the core code (Jeffy Chen)
- Add debug infrastructure for hierarchical irq domains (Thomas
Gleixner)
