Merge tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
"Here is the big set of driver core changes for 6.11-rc1.

Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:

- platform remove callback api final fixups (Uwe took many releases
to get here, finally!)

- Rust bindings for basic firmware apis and initial driver-core
interactions.

It's not all that useful for a "write a whole driver in rust" type
of thing, but the firmware bindings do help out the phy rust
drivers, and the driver core bindings give a solid base on which
others can start their work.

There is still a long way to go here before we have a multitude of
rust drivers being added, but it's a great first step.

- driver core const api changes.

This reached across all bus types, and there are some fix-ups for
some not-common bus types that linux-next and 0-day testing shook
out.

This work is being done to help make the rust bindings more safe,
as well as the C code, moving toward the end-goal of allowing us to
put driver structures into read-only memory. We aren't there yet,
but are getting closer.

- minor devres cleanups and fixes found by code inspection

- arch_topology minor changes

- other minor driver core cleanups

All of these have been in linux-next for a very long time with no
reported problems"

sysfs/cpu: Make crash_hotplug attribute world-readable

There is no reason to restrict access to this attribute, as it merely
reports whether crash elfcorehdr is automatically updated on CPU hot
plug/unplug and/or online/offline events.

Note that since commit 79365026f8694 ("crash: add a new kexec flag for
hotplug support"), this maps to the same flag which is world-accessible
through /sys/devices/system/memory/crash_hotplug.

driver core: have match() callback in struct bus_type take a const *

In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *. This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.

Because the match() callback is in all busses, all busses are modified
to handle this properly. This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.

For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:
"The biggest part is the virtual CPU hotplug that touches ACPI,
irqchip. We also have some GICv3 optimisation for pseudo-NMIs that has
been queued via the arm64 tree. Otherwise the usual perf updates,
kselftest, various small cleanups.

Core:

- Virtual CPU hotplug support for arm64 ACPI systems

- cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
bits visible to guests

- CPU errata: expand the speculative SSBS workaround to more CPUs

- GICv3, use compile-time PMR values: optimise the way regular IRQs
are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
need for a static key in fast paths by using a priority value
chosen dynamically at boot time

ACPI:

- 'acpi=nospcr' option to disable SPCR as default console for arm64

- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/

Perf updates:

- Rework of the IMX PMU driver to enable support for I.MX95

- Enable support for tertiary match groups in the CMN PMU driver

- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4

- Add missing PMU driver MODULE_DESCRIPTION() strings

- Hook up DT compatibles for recent CPU PMUs

Kselftest updates:

- Kernel mode NEON fp-stress

- Cleanups, spelling mistakes

Miscellaneous:

- arm64 Documentation update with a minor clarification on TBI

- Fix missing IPI statistics

- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)

- Make MTE checking of in-kernel asynchronous tag faults conditional
on KASAN being enabled

- Minor cleanups, typos"
