The dpll.yaml spec incorrectly omitted module-name and clock-id from the
pin-get operation reply specification, even though the kernel DPLL
implementation has always included these attributes in pin-get responses
since the initial implementation.
This spec inconsistency caused issues with the C YNL code generator.
The generated dpll_pin_get_rsp structure was missing these fields.
Fix the spec by adding module-name and clock-id to the pin-attrs reply
specification to match the actual kernel behavior.

'rustfmt', by default, formats imports in a way that is prone to
conflicts while merging and rebasing, since in some cases it condenses
several items into the same line.
Document in our guidelines that we will handle this for the moment with
the trailing empty comment workaround and make the tree 'rustfmt'-clean

"Rust 'rustfmt' cleanup
'rustfmt', by default, formats imports in a way that is prone to
conflicts while merging and rebasing, since in some cases it condenses
several items into the same line.
Document in our guidelines that we will handle this for the moment
with the trailing empty comment workaround and make the tree
'rustfmt'-clean again"

rust: bitmap: fix formatting
rust: cpufreq: fix formatting
rust: alloc: employ a trailing comment to keep vertical layout
docs: rust: add section on imports formatting
- Fix the handling of ZCR_EL2 in NV VMs
- Pick the correct translation regime when doing a PTW on
the back of a SEA
- Prevent userspace from injecting an event into a vcpu that isn't
initialised yet
- Move timer save/restore to the sysreg handling code, fixing EL2 timer
access in the process
- Add FGT-based trapping of MDSCR_EL1 to reduce the overhead of debug
- Fix trapping configuration when the host isn't GICv3
- Improve the detection of HCR_EL2.E2H being RES1
- Drop a spurious 'break' statement in the S1 PTW
- Don't try to access SPE when owned by EL3
Documentation updates:
- Document the failure modes of event injection
- Document that a GICv3 guest can be created on a GICv5 host
with FEAT_GCIE_LEGACY
Selftest improvements:
- Add a selftest for the effective value of HCR_EL2.AMO
- Address build warning in the timer selftest when building with clang
- Teach irqfd selftests about non-x86 architectures
- Add missing sysregs to the set_id_regs selftest
- Fix vcpu allocation in the vgic_lpi_stress selftest
- Correctly enable interrupts in the vgic_lpi_stress selftest
x86:

guest_memfd:
- Rework KVM_CAP_GUEST_MEMFD_MMAP (newly introduced in 6.18) into a more
generic KVM_CAP_GUEST_MEMFD_FLAGS
- Add a guest_memfd INIT_SHARED flag and require userspace to explicitly set

`rustfmt`, by default, formats imports in a way that is prone to conflicts
while merging and rebasing, since in some cases it condenses several
items into the same line.
For instance, Linus mentioned [1] that the following case:
use crate::{
fmt,
page::AsPageIter,
};
is compressed by `rustfmt` into:
use crate::{fmt, page::AsPageIter};
which is undesirable.
Similarly, `rustfmt` may put several items in the same line even if the
braces span already multiple lines, e.g.:
use kernel::{
acpi, c_str,
device::{property, Core},
of, platform,
};
The options that control the formatting behavior around imports are
generally unstable, and `rustfmt` releases do not allow to use nightly
features, unlike the compiler and other Rust tooling [2].
For the moment, we can introduce a workaround to prevent `rustfmt`
from compressing the example above -- the "trailing empty comment":
use crate::{
fmt,
page::AsPageIter, //
};
which is reminiscent of the trailing comma behavior in other formatters.
We already used empty comments for formatting purposes in the past,
e.g. in commit b9b701fce4 ("rust: clarify the language unstable features
in use").
In addition, `rustfmt` actually reformats with a vertical layout (i.e. it
does not put two items in the same line) when seeing such a comment,
i.e. it doesn't just preserve the formatting, which is good in the sense
that we can use it to easily reformat some imports, since it matches
the style we generally want to have.
A Git merge driver would help (suggested by Gary and Wedson), though
maintainers would need to set it up, the diffs would still be larger
and the formatting rules for imports would remain hard to predict.
Thus document the style that we will follow in the coding guidelines
by introducing a new section and explain how the trailing empty comment
works there too.
We discussed the issue with upstream Rust in our usual Rust <-> Rust
for Linux meeting [3], and there have also been a few other discussions
in parallel in issues [4][5] and Zulip [6]. We will see what happens,
but upstream Rust has already created a subteam of `rustfmt` to try
to overcome the bandwidth issue [7], which is a good signal, and some
organization work has already started (e.g. tracking issues). We will
continue our discussions with them about it.

====================
pull-request: can 2025-10-14
The first 2 paches are by Celeste Liu and target the gS_usb driver.
The first patch remove the limitation to 3 CAN interface per USB
device. The second patch adds the missing population of
net_device->dev_port.
The next 4 patches are by me and fix the m_can driver. They add a
missing pm_runtime_disable(), fix the CAN state transition back to
Error Active and fix the state after ifup and suspend/resume.
Another patch by me targets the m_can driver, too and replaces Dong
Aisheng's old email address.
The next 2 patches are by Vincent Mailhol and update the CAN
networking Documentation.
Tetsuo Handa contributes the last patch that add missing cleanup calls
in the NETDEV_UNREGISTER notification handler.

The CAN-FD section of can.rst still states that there is a 1:1 mapping
between the Classical CAN DLC and its length. This is only true for
the DLC values up to 8. Beyond that point, the length remains at 8.
For reference, the mapping between the CAN DLC and the length is given
in below table [1]:

Remove the erroneous statement. Instead just state that the length of
a Classical CAN frame ranges from 0 to 8.

The ports definition currently defined in the usb-switch.yaml
fits standards devices which are either recipient of altmode
muxing and orientation switching events or an element of the
USB Super Speed data lanes.
This doesn't necessarely fit combo PHYs like the Qualcomm
USB3/DP Combo which has a different ports representation.

Add a guest_memfd flag to allow userspace to state that the underlying
memory should be configured to be initialized as shared, and reject user
page faults if the guest_memfd instance's memory isn't shared. Because
KVM doesn't yet support in-place private<=>shared conversions, all
guest_memfd memory effectively follows the initial state.
Alternatively, KVM could deduce the initial state based on MMAP, which for
all intents and purposes is what KVM currently does. However, implicitly
deriving the default state based on MMAP will result in a messy ABI when
support for in-place conversions is added.
For x86 CoCo VMs, which don't yet support MMAP, memory is currently private
by default (otherwise the memory would be unusable). If MMAP implies
memory is shared by default, then the default state for CoCo VMs will vary
based on MMAP, and from userspace's perspective, will change when in-place
conversion support is added. I.e. to maintain guest<=>host ABI, userspace
would need to immediately convert all memory from shared=>private, which
is both ugly and inefficient. The inefficiency could be avoided by adding
a flag to state that memory is _private_ by default, irrespective of MMAP,
but that would lead to an equally messy and hard to document ABI.
Bite the bullet and immediately add a flag to control the default state so
that the effective behavior is explicit and straightforward.

Rework the not-yet-released KVM_CAP_GUEST_MEMFD_MMAP into a more generic
KVM_CAP_GUEST_MEMFD_FLAGS capability so that adding new flags doesn't
require a new capability, and so that developers aren't tempted to bundle
multiple flags into a single capability.
Note, kvm_vm_ioctl_check_extension_generic() can only return a 32-bit
value, but that limitation can be easily circumvented by adding e.g.
KVM_CAP_GUEST_MEMFD_FLAGS2 in the unlikely event guest_memfd supports more
than 32 flags.
