Pull x86 kvm updates from Paolo Bonzini:
"x86:
- KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or
deleted.
This does not traditionally have particularly noticeable overhead,
but Intel's TDX will require the guest to re-accept private pages
if they are dropped from the secure EPT, which is a non starter.
Actually, the only reason why this is not already being done is a
bug which was never fully investigated and caused VM instability
with assigned GeForce GPUs, so allow userspace to opt into the new
behavior.
- Advertise AVX10.1 to userspace (effectively prep work for the
"real" AVX10 functionality that is on the horizon)
- Rework common MSR handling code to suppress errors on userspace
accesses to unsupported-but-advertised MSRs
This will allow removing (almost?) all of KVM's exemptions for
userspace access to MSRs that shouldn't exist based on the vCPU
model (the actual cleanup is non-trivial future work)
- Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC)
splits the 64-bit value into the legacy ICR and ICR2 storage,
whereas Intel (APICv) stores the entire 64-bit value at the ICR
offset
- Fix a bug where KVM would fail to exit to userspace if one was
triggered by a fastpath exit handler
- Add fastpath handling of HLT VM-Exit to expedite re-entering the
guest when there's already a pending wake event at the time of the
exit
- Fix a WARN caused by RSM entering a nested guest from SMM with
invalid guest state, by forcing the vCPU out of guest mode prior to
signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the
nested guest)
- Overhaul the "unprotect and retry" logic to more precisely identify
cases where retrying is actually helpful, and to harden all retry
paths against putting the guest into an infinite retry loop
- Add support for yielding, e.g. to honor NEED_RESCHED, when zapping
rmaps in the shadow MMU
- Refactor pieces of the shadow MMU related to aging SPTEs in
prepartion for adding multi generation LRU support in KVM
- Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is
enabled, i.e. when the CPU has already flushed the RSB
- Trace the per-CPU host save area as a VMCB pointer to improve
readability and cleanup the retrieval of the SEV-ES host save area
- Remove unnecessary accounting of temporary nested VMCB related
allocations
- Set FINAL/PAGE in the page fault error code for EPT violations if
and only if the GVA is valid. If the GVA is NOT valid, there is no
guest-side page table walk and so stuffing paging related metadata
is nonsensical
- Fix a bug where KVM would incorrectly synthesize a nested VM-Exit
instead of emulating posted interrupt delivery to L2
- Add a lockdep assertion to detect unsafe accesses of vmcs12
structures
- Harden eVMCS loading against an impossible NULL pointer deref
(really truly should be impossible)
- Minor SGX fix and a cleanup
- Misc cleanups
Generic:
- Register KVM's cpuhp and syscore callbacks when enabling
virtualization in hardware, as the sole purpose of said callbacks
is to disable and re-enable virtualization as needed
- Enable virtualization when KVM is loaded, not right before the
first VM is created
Together with the previous change, this simplifies a lot the logic
of the callbacks, because their very existence implies
virtualization is enabled
- Fix a bug that results in KVM prematurely exiting to userspace for
coalesced MMIO/PIO in many cases, clean up the related code, and
add a testcase
- Fix a bug in kvm_clear_guest() where it would trigger a buffer
overflow _if_ the gpa+len crosses a page boundary, which thankfully
is guaranteed to not happen in the current code base. Add WARNs in
more helpers that read/write guest memory to detect similar bugs
Selftests:
- Fix a goof that caused some Hyper-V tests to be skipped when run on
bare metal, i.e. NOT in a VM
- Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES
guest
- Explicitly include one-off assets in .gitignore. Past Sean was
completely wrong about not being able to detect missing .gitignore
entries
- Verify userspace single-stepping works when KVM happens to handle a
VM-Exit in its fastpath
- Misc cleanups"

access_coordinate calculation, as well as a change to remove locking
from memory notifier callback.
In addition, a number of misc cleanups and refactoring of the code are

- Preserve the CDAT access_coordinate from an endpoint
- Add the support for shared upstream link access_coordinate calculation
- Add documentation to explain how the calculations are done
Remove locking from memory notifier callback.
Misc cleanups:

no_llseek had been defined to NULL two years ago, in commit 868941b14441
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.

The iptables example was added in commit d2f26037a38a (netfilter: Add
documentation for tproxy, 2008-10-08), but xt_socket 'transparent'
option was added in commit a31e1ffd2231 (netfilter: xt_socket: added new
revision of the 'socket' match supporting flags, 2009-06-09).
Now add the 'transparent' option to the iptables example to ignore
non-transparent sockets, which is also consistent with the nft example.

goodix,gt7986u.example.dtb:
touchscreen@0: compatible: 'oneOf' conditional failed, one must be fixed:
['goodix,gt7986u'] is too short
'goodix,gt7375p' was expected
This was reported on mailing list on 6th of September, but no reaction
happened from contributor or maintainer to fix it.
Therefore let's drop binding which breaks and duplicates existing one.

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up
objtool warnings), teach objtool about 'noreturn' Rust symbols and
mimic '___ADDRESSABLE()' for 'module_{init,exit}'. With that, we
should be objtool-warning-free, so enable it to run for all Rust
object files.
- KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
- Support 'RUSTC_VERSION', including re-config and re-build on
change.
- Split helpers file into several files in a folder, to avoid
conflicts in it. Eventually those files will be moved to the right
places with the new build system. In addition, remove the need to
manually export the symbols defined there, reusing existing
machinery for that.
- Relax restriction on configurations with Rust + GCC plugins to just
the RANDSTRUCT plugin.
'kernel' crate:
- New 'list' module: doubly-linked linked list for use with reference
counted values, which is heavily used by the upcoming Rust Binder.
This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
unique for the given ID), 'AtomicTracker' (tracks whether a
'ListArc' exists using an atomic), 'ListLinks' (the prev/next
pointers for an item in a linked list), 'List' (the linked list
itself), 'Iter' (an iterator over a 'List'), 'Cursor' (a cursor
into a 'List' that allows to remove elements), 'ListArcField' (a
field exclusively owned by a 'ListArc'), as well as support for
heterogeneous lists.
- New 'rbtree' module: red-black tree abstractions used by the
upcoming Rust Binder.
This includes 'RBTree' (the red-black tree itself), 'RBTreeNode' (a
node), 'RBTreeNodeReservation' (a memory reservation for a node),
'Iter' and 'IterMut' (immutable and mutable iterators), 'Cursor'
(bidirectional cursor that allows to remove elements), as well as
an entry API similar to the Rust standard library one.
- 'init' module: add 'write_[pin_]init' methods and the
'InPlaceWrite' trait. Add the 'assert_pinned!' macro.
- 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
introducing an associated type in the trait.
- 'alloc' module: add 'drop_contents' method to 'BoxExt'.
- 'types' module: implement the 'ForeignOwnable' trait for
'Pin<Box<T>>' and improve the trait's documentation. In addition,
add the 'into_raw' method to the 'ARef' type.
- 'error' module: in preparation for the upcoming Rust support for
32-bit architectures, like arm, locally allow Clippy lint for
those.
Documentation:
- https://rust.docs.kernel.org has been announced, so link to it.
- Enable rustdoc's "jump to definition" feature, making its output a
bit closer to the experience in a cross-referencer.
- Debian Testing now also provides recent Rust releases (outside of
the freeze period), so add it to the list.

Introduce the advanced extended interrupt controllers (AVECINTC). This
feature will allow each core to have 256 independent interrupt vectors
and MSI interrupts can be independently routed to any vector on any CPU.
The whole topology of irqchips in LoongArch machines looks like this if
AVECINTC is supported:

Pull clk updates from Stephen Boyd:
"The core clk framework is left largely untouched this time around
except for support for the newly ratified DT property
'assigned-clock-rates-u64'.
I'm much more excited about the support for loading DT overlays from
KUnit tests so that we can test how the clk framework parses DT nodes
during clk registration. The clk framework has some places that are
highly DeviceTree dependent so this charts the path to extend the
KUnit tests to cover even more framework code in the future. I've got
some more tests on the list that use the DT overlay support, but they
uncovered issues with clk unregistration that I'm still working on
fixing.
Outside the core, the clk driver update pile is dominated by Qualcomm
and Renesas SoCs, making it fairly usual. Looking closer, there are
fixes for things all over the place, like adding missing clk
frequencies or moving defines for the number of clks out of DT binding
headers into the drivers. There are even conversions of DT bindings to
YAML and migration away from strings to describe clk topology. Overall
it doesn't look unusual so I expect the new drivers to be where we'll
have fixes in the coming weeks.
Core:
- KUnit tests for clk registration and fixed rate basic clk type

Pull i2c updates from Wolfram Sang:
"I2C core:
- finally remove the I2C_COMPAT symbol after 15 years of deprecation
- lock client addresses during initialization to prevent race
conditions between different kinds of instantiation
- use scoped foreach OF child loops
- testunit cleanups and documentation improvements, as well as two
new tests, one for repeated start and one for triggering SMBusAlert
interrupts
I2C host drivers:
- DesignWare and Renesas I2C driver updates.
The first has has undergone through a series of cleanups that have
been sent to the mailing list a year ago for the first time and
finally get merged in this pull request. They are many, from typos
(e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
functions to librarieas) and many others.
- all the DesignWare Kconfig options have been grouped under the
I2C_DESIGNWARE_CORE and this required some adaptation in many of
the kernel configuration files for different arm and mips boards
Cleanups:
- improve the exit path in the runtime resume function for the
Qualcomm Geni platform
- get rid of the unused "target_addr" parameter in the Intel LJCA
driver
- intialize the restart_flag in the MediaTek controller in one single
place
- constify a few global data structures in the virtio driver
- simplify the bus speed handling in the Renesas driver init function
making it more readable
- improved probe function of the Renesas R-Car driver
- switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
SET_RUNTIME_PM_OPS()
- iMX/MXC driver cleanups
- use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
and MPC drivers
Refactoring:
- Fix a potential out of boundary array access in the Nuvoton driver.
This is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The change
makes the driver more future proof and, at the same time, silences
code analyzers.
Improvements:
- several patches improving the runtime power management handling of
the Renesas I2C (riic) driver
- use a more descriptive adapter name in the Intel i801 driver to
show the presence of the IDF feature
- kill pending transactions when irq's can't complete their handling
in the Intel Denverton (ismt) driver, triggering a timeout
New Feature:
- support fast mode plus in the Renesas I2C (riic) driver
New support:
- Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
- new i2c-keba.c driver
- new driver for The Mule i2c multiplexer
Core I2C framework:
- move runtime PM functions in order to allow them to be accessed
during device add
Devicetree:
- nVidia and Qualcomm binding improvements
- get rid of redundant "multi-master" property in the aspeed binding
- convert i2c-sprd binding to YAML
AT24 updates:
- document a new model from giantec in DT bindings"

Pull firewire updates from Takashi Sakamoto:
"In the FireWire subsystem, tasklets have been used as the bottom half
of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
become available, and some developers have proposed replacing the
tasklet with a BH workqueue.
As a first step towards dropping tasklet use, the 1394 OHCI
isochronous context can use regular workqueues. In this context, the
batch of packets is processed in the specific queue, thus the timing
jitter caused by task scheduling is not so critical.
Additionally, DMA transmission can be scheduled per-packet basis,
therefore the context can be sleep between the operation of
transmissions. Furthermore, in-kernel protocol implementation involves
some CPU-bound tasks, which can sometimes consumes CPU time so long.
These characteristics suggest that normal workqueues are suitable,
through BH workqueues are not.
The replacement with a workqueue allows unit drivers to process the
content of packets in non-atomic context. It brings some reliefs to
some drivers in sound subsystem that spin-lock is not mandatory
anymore during isochronous packet processing.
Summary:
- Replace tasklet with workqueue for isochronous context
- Replace IDR with XArray
- Utilize guard macro where possible
- Print deprecation warning when enabling debug parameter of
firewire-ohci module
- Switch to nonatomic PCM operation"

This section answers a new FAQ entry:
9. How does LOCALIO make certain that object lifetimes are managed
properly given NFSD and NFS operate in different contexts?
See the detailed "NFS Client and Server Interlock" section below.
The first half of the section details NeilBrown's elegant design
for LOCALIO's nfs_uuid_t based interlock and is heavily based on
Neil's "net namespace refcounting" description here:
https://marc.info/?l=linux-nfs&m=172498546024767&w=2
The second half of the section details the per-cpu-refcount introduced
to ensure NFSD's nfsd_serv isn't destroyed while in use by a LOCALIO
client.

This document gives an overview of the LOCALIO auxiliary RPC protocol
added to the Linux NFS client and server to allow them to reliably
handshake to determine if they are on the same host.
Once an NFS client and server handshake as "local", the client will
bypass the network RPC protocol for read, write and commit operations.
Due to this XDR and RPC bypass, these operations will operate faster.

Building external modules is typically done using this command:
$ make -C <KERNEL_DIR> M=<EXTMOD_DIR>
Here, <KERNEL_DIR> refers to the output directory where the kernel was
built, not the kernel source directory.
When the kernel is built in the source tree, there is no ambiguity, as
the output directory and the source directory are the same.
If the kernel was built in a separate build directory, <KERNEL_DIR>
should be the kernel output directory. Otherwise, Kbuild cannot locate
necessary build artifacts. This has been the method for building
external modules against a pre-built kernel in a separate directory
for over 20 years. [1]
If you pass the kernel source directory to the -C option, you must also
specify the kernel build directory using the O= option. This approach
works as well, though it results in a slightly longer command:
$ make -C <KERNEL_SOURCE_DIR> O=<KERNEL_BUILD_DIR> M=<EXTMOD_DIR>
Some people mistakenly believe that O= should specify a build directory
for external modules when used together with M=. This commit adds more
clarification to Documentation/kbuild/kbuild.rst.
