Add missing reg minItems as based on current binding document
only ethernet MAC IO space is a supported configuration.
There is a bug in schema, current examples contain 64-bit
addressing as well as 32-bit addressing. The schema validation
does pass incidentally considering one 64-bit reg address as
two 32-bit reg address entries. If we change axi_ethernet_eth1
example node reg addressing to 32-bit schema validation reports:
Documentation/devicetree/bindings/net/xlnx,axi-ethernet.example.dtb:
ethernet@40000000: reg: [[1073741824, 262144]] is too short
To fix it add missing reg minItems constraints and to make things clearer
stick to 32-bit addressing in examples.

Merge series from Alexey Klimov <alexey.klimov@linaro.org>:
This series still keeps "qcom,qrb4210-rb2-sndcard" for sm8250 soundcard. As per
off the list discussion with Srini it was suggested to have it since in future it
may be required to add clocks, workarounds, quirks, model-specific things based on
this compatible. The same as for RB5 compatible in sm8250 snd driver.
This focuses on HDMI audio playback only hence there are no soundwire and dmic pins,
for instance. The work to enable playback via wcd+wsa8815 amplifier is in progress (it works)
and one of the routes is to merge such two patchsets together.
Link to prev series:
https://lore.kernel.org/linux-sound/20240628010715.438471-1-alexey.klimov@linaro.org/
My understanding of the interrupts property is that it can either be:
1/ - TX
2/ - TX
- RX
3/ - Common/combined.
There are very little chances that either:
- TX
- Common/combined
or even
- TX
- RX
- Common/combined
could be a thing.
Looking at the interrupt-names definition (which uses oneOf instead of
anyOf), it makes indeed little sense to use anyOf in the interrupts
definition. I believe this is just a mistake, hence let's fix it.

A number of Arm Ltd CPUs suffer from errata whereby an MSR to the SSBS
special-purpose register does not affect subsequent speculative
instructions, permitting speculative store bypassing for a window of
time.
We worked around this for a number of CPUs in commits:
* 7187bb7d0b ("arm64: errata: Add workaround for Arm errata 3194386 and 3312417")
* 75b3c43eab ("arm64: errata: Expand speculative SSBS workaround")
* 145502cac7ea70b5 ("arm64: errata: Expand speculative SSBS workaround (again)")
Since then, a (hopefully final) batch of updates have been published,
with two more affected CPUs. For the affected CPUs the existing
mitigation is sufficient, as described in their respective Software
Developer Errata Notice (SDEN) documents:
* Cortex-A715 (MP148) SDEN v15.0, erratum 3456084https://developer.arm.com/documentation/SDEN-2148827/1500/
* Neoverse-N3 (MP195) SDEN v5.0, erratum 3456111
https://developer.arm.com/documentation/SDEN-3050973/0500/
Enable the existing mitigation by adding the relevant MIDRs to
erratum_spec_ssbs_list, and update silicon-errata.rst and the
Kconfig text accordingly.

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

from memory notifier callback.
In addition, a number of misc cleanups and refactoring of the code are

- Move all mailbox related data to 'struct cxl_mailbox'
- Refactor mailbox APIs with 'struct cxl_mailbox' as input instead of
memory device state
Add support for shared upstream link access_coordinate calculation for
configurations that have multiple targets under a switch or a root
port where the aggregated bandwidth can be greater than the upstream
link of the switch/RP upstream link:
- 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

no_llseek had been defined to NULL two years ago, in commit 868941b144

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.

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.

In addition, there are several patches to address corner cases of
atomic file operations and better support for file pinning on zoned
device.
Enhancement:
- add knobs to tune foreground/background GCs for Zoned devices
- convert IO paths to use folio
- reduce expensive checkpoint trigger frequency
- allow F2FS_IPU_NOCACHE for pinned file
- forcibly migrate to secure space for zoned device file pinning
- get rid of buffer_head use
- add write priority option based on zone UFS
- get rid of online repair on corrupted directory
Bug fixes:
- fix to don't panic system for no free segment fault injection
- fix to don't set SB_RDONLY in f2fs_handle_critical_error()
- avoid unused block when dio write in LFS mode
- compress: don't redirty sparse cluster during {,de}compress
- check discard support for conventional zones
- atomic: prevent atomic file from being dirtied before commit
- atomic: fix to check atomic_file in f2fs ioctl interfaces
- atomic: fix to forbid dio in atomic_file
- atomic: fix to truncate pagecache before on-disk metadata truncation
- atomic: create COW inode from parent dentry
- atomic: fix to avoid racing w/ GC
- atomic: require FMODE_WRITE for atomic write ioctls
- fix to wait page writeback before setting gcing flag
- fix to avoid racing in between read and OPU dio write, dio completion
- fix several potential integer overflows in file offsets and dir_block_index
- fix to avoid use-after-free in f2fs_stop_gc_thread()
As usual, there are several code clean-ups and refactorings"

Pull landlock updates from Mickaël Salaün:
"We can now scope a Landlock domain thanks to a new "scoped" field that
can deny interactions with resources outside of this domain.
The LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET flag denies connections to an
abstract UNIX socket created outside of the current scoped domain, and
the LANDLOCK_SCOPE_SIGNAL flag denies sending a signal to processes
outside of the current scoped domain.
These restrictions also apply to nested domains according to their
scope. The related changes will also be useful to support other kind
of IPC isolations"
