usually well contained to Documentation/ itself. Highlights include:
- The Chinese translators have been busy and show no signs of
stopping anytime soon. Italian has also caught up.
- Aditya Srivastava has been working on improvements to the
kernel-doc script.
- Thorsten continues his work on reporting-issues.rst and related
documentation around regression reporting.

Pull tty and serial driver updates from Greg KH:
"Here is the big set of tty and serial driver updates for 5.13-rc1.
Actually busy this release, with a number of cleanups happening:
- much needed core tty cleanups by Jiri Slaby
- removal of unused and orphaned old-style serial drivers. If anyone
shows up with this hardware, it is trivial to restore these but we
really do not think they are in use anymore.
- fixes and cleanups from Johan Hovold on a number of termios setting
corner cases that loads of drivers got wrong as well as removing
unneeded code due to tty core changes from long ago that were never
propagated out to the drivers
- loads of platform-specific serial port driver updates and fixes
- coding style cleanups and other small fixes and updates all over
the tty/serial tree.
All of these have been in linux-next for a while now with no reported
issues"

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for this
failed "experiment".
- removal of the Google gasket driver, turns out no one wanted to
maintain it or cares about it anymore, so they asked for it to be
removed.
- comedi finally moves out of the staging directory into drivers/comedi
This is one of the oldest kernel subsystems around, being created
in the 2.0 kernel days, and was one of the first things added to
drivers/staging/ when that was created over 15 years ago.
It should have been moved out of staging a long time ago, it's well
maintained and used by loads of different devices in the real world
every day. Nice to see this finally happen.
- so many tiny coding style cleanups it's not funny.
Perfect storm of at least 2 different intern project application
deadlines combined to provide a huge number of new contributions in
this area from people learning how to do kernel development. Great
job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers
and updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues"

The VIDIOC_G/S/TRY_EXT_CTRLS documentation has large explanatory texts for
some of the fields in a table. This makes it hard to read. Move those text
to a new cell spanning the whole width of the table, similar to what was
done for struct v4l2_pix_format. This makes it much more readable.
Also move the 'ctrl_class' description to below the 'which' description and
just mention that it is deprecated and that 'which' should be used instead.
Finally remove 'note::' for the V4L2_CTRL_WHICH_DEF_VAL description. It
doesn't have to be marked as a note, it's just a simple paragraph.

Until now, the VP8 V4L2 API was not exported as a public API,
and only defined in a private media header (media/vp8-ctrls.h).
The reason for this was a concern about the API not complete
and ready to support VP8 decoding hardware accelerators.
After reviewing the VP8 specification in detail, and now
that the API is able to support Cedrus and Hantro G1,
we can consider this ready.

The Microsoft Surface Book series devices consist of a so-called
clipboard part (containing the CPU, touchscreen, and primary battery)
and a base part (containing keyboard, secondary battery, and optional
discrete GPU). These parts can be separated, i.e. the clipboard can be
detached and used as tablet.
This detachment process is initiated by pressing a button. On the
Surface Book 2 and 3 (targeted with this commit), the Surface Aggregator
Module (i.e. the embedded controller on those devices) attempts to send
a notification to any listening client driver and waits for further
instructions (i.e. whether the detachment process should continue or be
aborted). If it does not receive a response in a certain time-frame, the
detachment process (by default) continues and the clipboard can be
physically separated. In other words, (by default and) without a driver,
the detachment process takes about 10 seconds to complete.
This commit introduces a driver for this detachment system (called DTX).
This driver allows a user-space daemon to control and influence the
detachment behavior. Specifically, it forwards any detachment requests
to user-space, allows user-space to make such requests itself, and
allows handling of those requests. Requests can be handled by either
aborting, continuing/allowing, or delaying (i.e. resetting the timeout
via a heartbeat commend). The user-space API is implemented via the
/dev/surface/dtx miscdevice.
In addition, user-space can change the default behavior on timeout from
allowing detachment to disallowing it, which is useful if the (optional)
discrete GPU is in use.
Furthermore, this driver allows user-space to receive notifications
about the state of the base, specifically when it is physically removed
(as opposed to detachment requested), in what manner it is connected
(i.e. in reverse-/tent-/studio- or laptop-mode), and what type of base
is connected. Based on this information, the driver also provides a
simple tablet-mode switch (aliasing all modes without keyboard access,
i.e. tablet-mode and studio-mode to its reported tablet-mode).
An implementation of such a user-space daemon, allowing configuration of
detachment behavior via scripts (e.g. safely unmounting USB devices
connected to the base before continuing) can be found at [1].

The Cyclades driver was orphaned by commit d459883e6c54 (MAINTAINERS:
remove two dead e-mail) 13 years ago. Noone stepped up to take care of
them and to fix all the issues the driver has.
On the top of that, there is no way to obtain the firmware for Z cards
from the vendor as cyclades.com ceased to exist.
So it's time to drop the driver with all its traces.

Pull char/misc driver updates from Greg KH:
"Here is the large set of char/misc/whatever driver subsystem updates
for 5.12-rc1. Over time it seems like this tree is collecting more and
more tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86 maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only
reported issue being a merge conflict due to the dfl_device_id
addition from the fpga subsystem in here"

Pull initial support for CXL (Compute Express Link) from Dan Williams:
"Introduce an initial driver for CXL 2.0 Type-3 Memory Devices.
CXL is Compute Express Link which released the 2.0 specification in
November. The Linux relevant changes in CXL 2.0 are support for an OS
to dynamically assign address space to memory devices, support for
switches, persistent memory, and hotplug.
A Type-3 Memory Device is a PCI enumerated device presenting the CXL
Memory Device Class Code and implementing the CXL.mem protocol.
CXL.mem allows device to advertise CPU and I/O coherent memory to the
system, i.e. typical "System RAM" and "Persistent Memory" in Linux
/proc/iomem terms.
In addition to the CXL.mem fast path there is an administrative
command hardware mailbox interface for maintenance and provisioning.
It is this command interface that is the focus of the initial driver.
With this driver a CXL device that is mapped by the BIOS can be
administered by Linux.
Linux support for CXL PMEM and dynamic CXL address space management
are to be implemented post v5.12"

Add a straightforward IOCTL that provides a mechanism for userspace to
query the supported memory device commands. CXL commands as they appear
to userspace are described as part of the UAPI kerneldoc. The command
list returned via this IOCTL will contain the full set of commands that
the driver supports, however, some of those commands may not be
available for use by userspace.
Memory device commands first appear in the CXL 2.0 specification. They
are submitted through a mailbox mechanism specified in the CXL 2.0
specification.
The send command allows userspace to issue mailbox commands directly to
the hardware. The list of available commands to send are the output of
the query command. The driver verifies basic properties of the command
and possibly inspect the input (or output) payload to determine whether
or not the command is allowed (or might taint the kernel).

The VM management interfaces expose several VM operations to ACRN
userspace via ioctls. For example, creating VM, starting VM, destroying
VM and so on.
The ACRN Hypervisor needs to exchange data with the ACRN userspace
during the VM operations. HSM provides VM operation ioctls to the ACRN
userspace and communicates with the ACRN Hypervisor for VM operations
via hypercalls.
HSM maintains a list of User VM. Each User VM will be bound to an
existing file descriptor of /dev/acrn_hsm. The User VM will be
destroyed when the file descriptor is closed.
