Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.
Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.
So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

KVM PPC update for 5.7
* Add a capability for enabling secure guests under the Protected
Execution Framework ultravisor
* Various bug fixes and cleanups.
patch_realtek.c has historically failed to properly configure the PC
Beep Hidden Register for the ALC256 codec (among others). Depending on
your kernel version, symptoms of this misconfiguration can range from
chassis noise, picked up by a poorly-shielded PCBEEP trace, getting
amplified and played on your internal speaker and/or headphones to loud
feedback, which responds to the "Headphone Mic Boost" ALSA control,
getting played through your headphones. For details of the problem, see
the patch in this series titled "ALSA: hda/realtek - Set principled PC
Beep configuration for ALC256", which fixes the configuration.
These symptoms have been most noticed on the Dell XPS 13 9350 and 9360,
popular laptops that use the ALC256. As a result, several model-specific
fixups have been introduced to try and fix the problem, the most
egregious of which locks the "Headphone Mic Boost" control as a hack to
minimize noise from a feedback loop that shouldn't have been there in
the first place.
Now that the underlying issue has been fixed, remove all these fixups.
Remaining fixups needed by the XPS 13 are all picked up by existing pin
quirks.
This change should, for the XPS 13 9350/9360
- Significantly increase volume and audio quality on headphones
- Eliminate headphone popping on suspend/resume
- Allow "Headphone Mic Boost" to be set again, making the headphone
jack fully usable as a microphone jack too.

This codec (among others) has a hidden set of audio routes, apparently
designed to allow PC Beep output without a mixer widget on the output
path, which are controlled by an undocumented Realtek vendor register.
The default configuration of these routes means that certain inputs
aren't accessible, necessitating driver control of the register.
However, Realtek has provided no documentation of the register, instead
opting to fix issues by providing magic numbers, most of which have been
at least somewhat erroneous. These magic numbers then get copied by
others into model-specific fixups, leading to a fragmented and buggy set
of configurations.
To get out of this situation, I've reverse engineered the register by
flipping bits and observing how the codec's behavior changes. This
commit documents my findings. It does not change any code.

Pull x86 splitlock updates from Thomas Gleixner:
"Support for 'split lock' detection:
Atomic operations (lock prefixed instructions) which span two cache
lines have to acquire the global bus lock. This is at least 1k cycles
slower than an atomic operation within a cache line and disrupts
performance on other cores. Aside of performance disruption this is a
unpriviledged form of DoS.
Some newer CPUs have the capability to raise an #AC trap when such an
operation is attempted. The detection is by default enabled in warning
mode which will warn once when a user space application is caught. A
command line option allows to disable the detection or to select fatal
mode which will terminate offending applications with SIGBUS"

"The main changes in this cycle are:
- Various NUMA scheduling updates: harmonize the load-balancer and
NUMA placement logic to not work against each other. The intended
result is better locality, better utilization and fewer migrations.
- Introduce Thermal Pressure tracking and optimizations, to improve
task placement on thermally overloaded systems.
- Implement frequency invariant scheduler accounting on (some) x86
CPUs. This is done by observing and sampling the 'recent' CPU
frequency average at ~tick boundaries. The CPU provides this data
via the APERF/MPERF MSRs. This hopefully makes our capacity
estimates more precise and keeps tasks on the same CPU better even
if it might seem overloaded at a lower momentary frequency. (As
usual, turbo mode is a complication that we resolve by observing
the maximum frequency and renormalizing to it.)

x86 specific hacks which are increasingly difficult to maintain.
There's hope that all future extensions will now go through that
boot protocol.

The main changes are:
- Boot time GDT handling changes
- Simplify handling of EFI properties table on arm64
- Generic EFI stub cleanups, to improve command line handling, file
I/O, memory allocation, etc.
- Introduce a generic initrd loading method based on calling back
into the firmware, instead of relying on the x86 EFI handover
protocol or device tree.
- Introduce a mixed mode boot method that does not rely on the x86
EFI handover protocol either, and could potentially be adopted by
other architectures (if another one ever surfaces where one
execution mode is a superset of another)
- Clean up the contents of 'struct efi', and move out everything that
doesn't need to be stored there.
- Incorporate support for UEFI spec v2.8A changes that permit
firmware implementations to return EFI_UNSUPPORTED from UEFI
runtime services at OS runtime, and expose a mask of which ones are
supported or unsupported via a configuration table.

Pull power management updates from Rafael Wysocki:
"These clean up and rework the PM QoS API, address a suspend-to-idle
wakeup regression on some ACPI-based platforms, clean up and extend a
few cpuidle drivers, update multiple cpufreq drivers and cpufreq
documentation, and fix a number of issues in devfreq and several other
things all over.
Specifics:
- Clean up and rework the PM QoS API to simplify the code and reduce
the size of it (Rafael Wysocki).
- Fix a suspend-to-idle wakeup regression on Dell XPS13 9370 and
similar platforms where the USB plug/unplug events are handled by
the EC (Rafael Wysocki).
- CLean up the intel_idle and PSCI cpuidle drivers (Rafael Wysocki,
Ulf Hansson).
- Extend the haltpoll cpuidle driver so that it can be forced to run
on some systems where it refused to load (Maciej Szmigiero).
- Convert several cpufreq documents to the .rst format and move the
legacy driver documentation into one common file (Mauro Carvalho
Chehab, Rafael Wysocki).
- Update several cpufreq drivers:
* Extend and fix the imx-cpufreq-dt driver (Anson Huang).
* Improve the -EPROBE_DEFER handling and fix unwanted CPU
overclocking on i.MX6ULL in imx6q-cpufreq (Anson Huang,
Christoph Niedermaier).
* Add support for Krait based SoCs to the qcom driver (Ansuel
Smith).
* Add support for OPP_PLUS to ti-cpufreq (Lokesh Vutla).
* Add platform specific intermediate callbacks support to
cpufreq-dt and update the imx6q driver (Peng Fan).
* Simplify and consolidate some pieces of the intel_pstate
driver and update its documentation (Rafael Wysocki, Alex
Hung).
- Fix several devfreq issues:
* Remove unneeded extern keyword from a devfreq header file and
use the DEVFREQ_GOV_UPDATE_INTERNAL event name instead of
DEVFREQ_GOV_INTERNAL (Chanwoo Choi).
* Fix the handling of dev_pm_qos_remove_request() result
(Leonard Crestez).
* Use constant name for userspace governor (Pierre Kuo).
* Get rid of doc warnings and fix a typo (Christophe JAILLET).
- Use built-in RCU list checking in some places in the PM core to
avoid false-positive RCU usage warnings (Madhuparna Bhowmik).
- Add explicit READ_ONCE()/WRITE_ONCE() annotations to low-level PM
QoS routines (Qian Cai).
- Fix removal of wakeup sources to avoid NULL pointer dereferences in
a corner case (Neeraj Upadhyay).

related documentation (Eric Biggers).
- Update the idle_inject power capping driver to use variable-length
arrays instead of zero-length arrays (Gustavo Silva).
- Fix list format in a PM QoS document (Randy Dunlap).
- Make the cpufreq stats module use scnprintf() to avoid potential
buffer overflows (Takashi Iwai).
- Add pm_runtime_get_if_active() to PM-runtime API (Sakari Ailus).

Pull spi and regulator updates from Mark Brown:
"At one point in the release cycle I managed to fat finger things and
apply some SPI fixes onto a regulator branch and merge that into the
SPI tree, then pull in a change shared with the MTD tree moving the
Mediatek quadspi driver over to become the Mediatek spi-nor driver in
the SPI tree.
This has made a mess which I only just noticed while preparing this
and I can't see a sensible way to unpick things due to other
subsequent merge commits especially the pull from MTD so it looks like
the most sensible thing to do is give up and combine the two pull
requests.
Fortunately both subsystems were fairly quiet this cycle, the
highlights are:
regulator:
- Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869
and Qualcomm PMI8994 and SMB208.
SPI:
- Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
from Vladimir Oltean.
- Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved
from MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and
Qualcomm Atheros AR934x/QCA95xx"

Pull staging and IIO driver updates from Greg KH:
"Here is the big staging and IIO driver pull request for 5.7-rc1.
We again end up deleting more code than we added here, thanks to
finally getting rid of the old and obsolete wireless USB stuff, and
the exfat code (which is coming in again through the vfs tree in a
much cleaner version).
But some code does come back, with the octeon drivers being found to
actually be used in the wild, so those deletions are now reverted.
Other than those major things, just loads and loads of tiny checkpatch
cleanups all over the place, along with new IIO drivers and fixes.
All have been in linux-next with no reported issues"
