clk: clk-loongson2: add clock controller driver support

This driver provides support for clock controller on Loongson-2 SoC,
the Loongson-2 SoC uses a 100MHz clock as the PLL reference clock,
there are five independent PLLs inside, each of which PLL can
provide up to three sets of frequency dependent clock outputs.

platform/x86: Add new msi-ec driver

Add a new driver to allow various MSI laptops' functionalities to be
controlled from userspace. This includes such features as power
profiles (aka shift modes), fan speed, charge thresholds, LEDs, etc.

This driver contains EC memory configurations for different firmware
versions and exports battery charge thresholds to userspace (note,
that start and end thresholds control the same EC parameter
and are always 10% apart).

docs: describe how to quickly build a trimmed kernel

Add a text explaining how to quickly build a kernel, as that's something
users will often have to do when they want to report an issue or test
proposed fixes. This is a huge and frightening task for quite a few
users these days, as many rely on pre-compiled kernels and have never
built their own. They find help on quite a few websites explaining the
process in various ways, but those howtos often omit important details
or make things too hard for the 'quickly build just for testing' case
that 'localmodconfig' is really useful for. Hence give users something
at hand to guide them, as that makes it easier for them to help with
testing, debugging, and fixing the kernel.

To keep the complexity at bay, the document explicitly focuses on how to
compile the kernel on commodity distributions running on commodity
hardware. People that deal with less common distributions or hardware
will often know their way around already anyway.

The text describes a few oddities of Arch and Debian that were found by
the author and a few volunteers that tested the described procedure.
There are likely more such quirks that need to be covered as well as a
few things the author will have missed -- but one has to start
somewhere.

The document heavily uses anchors and links to them, which makes things
slightly harder to read in the source form. But the intended target
audience is way more likely to read rendered versions of this text on
pages like docs.kernel.org anyway -- and there those anchors and links
allow easy jumps to the reference section and back, which makes the
document a lot easier to work with for the intended target audience.

Aspects relevant for bisection were left out on purpose, as that is a
related, but in the end different use case. The rough plan is to have a
second document with a similar style to cover bisection. The idea is to
reuse a few bits from this document and link quite often to entries in
the reference section with the help of the anchors in this text.

vhost_task: Allow vhost layer to use copy_process

Qemu will create vhost devices in the kernel which perform network, SCSI,
etc IO and management operations from worker threads created by the
kthread API. Because the kthread API does a copy_process on the kthreadd
thread, the vhost layer has to use kthread_use_mm to access the Qemu
thread's memory and cgroup_attach_task_all to add itself to the Qemu
thread's cgroups, and it bypasses the RLIMIT_NPROC limit which can result
in VMs creating more threads than the admin expected.

This patch adds a new struct vhost_task which can be used instead of
kthreads. They allow the vhost layer to use copy_process and inherit
the userspace process's mm and cgroups, the task is accounted for
under the userspace's nproc count and can be seen in its process tree,
and other features like namespaces work and are inherited by default.

MAINTAINERS: Update s390-iommu driver maintainer information

The s390 DMA API conversion changes currently under review will extend
the use of the s390-iommu driver to the DMA API. With s390's mandatory
use of an IOMMU this means all DMA for PCI devices will then use the
s390-iommu driver. With this in mind and considering my involvement in
these changes it makes sense to reflect this increased interdependence
in the maintainer structure. Thus add myself as first maintainer and
move Gerald to reviewer status.

The CS35L56 combines a high-performance mono audio amplifier, Class-H
tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost
converter supporting Class-H tracking.

Supported control interfaces are I2C, SPI or SoundWire.
Supported audio interfaces are I2S/TDM or SoundWire.

Most chip functionality is controlled by on-board ROM firmware that is
always running. The driver must apply patch/tune to the firmware
before using the CS35L56.

net: pcs: add driver for MediaTek SGMII PCS

The SGMII core found in several MediaTek SoCs is identical to what can
also be found in MediaTek's MT7531 Ethernet switch IC.
As this has not always been clear, both drivers developed different
implementations to deal with the PCS.
Recently Alexander Couzens pointed out this fact which lead to the
development of this shared driver.

Add a dedicated driver, mostly by copying the code now found in the
Ethernet driver. The now redundant code will be removed by a follow-up
commit.
