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

Pull more arm64 updates from Catalin Marinas:
"The main 'feature' is a workaround for C1-Pro erratum 4193714
requiring IPIs during TLB maintenance if a process is running in user
space with SME enabled.

The hardware acknowledges the DVMSync messages before completing
in-flight SME accesses, with security implications. The workaround
makes use of the mm_cpumask() to track the cores that need
interrupting (arm64 hasn't used this mask before).

The rest are fixes for MPAM, CCA and generated header that turned up
during the merging window or shortly before.

Summary:

Core features:

- Add workaround for C1-Pro erratum 4193714 - early CME (SME unit)
DVMSync acknowledgement. The fix consists of sending IPIs on TLB
maintenance to those CPUs running in user space with SME enabled

- Include kernel-hwcap.h in list of generated files (missed in a
recent commit generating the KERNEL_HWCAP_* macros)

CCA:

- Fix RSI_INCOMPLETE error check in arm-cca-guest

MPAM:

- Fix an unmount->remount problem with the CDP emulation,
uninitialised variable and checker warnings"

Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.

On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.

The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.

Core features:

- Add support for FEAT_LSUI, allowing futex atomic operations without
toggling Privileged Access Never (PAN)

- Further refactor the arm64 exception handling code towards the
generic entry infrastructure

- Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
through it

Memory management:

- Refactor the arm64 TLB invalidation API and implementation for
better control over barrier placement and level-hinted invalidation

- Enable batched TLB flushes during memory hot-unplug

- Fix rodata=full block mapping support for realm guests (when
BBML2_NOABORT is available)

Perf and PMU:

- Add support for a whole bunch of system PMUs featured in NVIDIA's
Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
for CPU/C2C memory latency PMUs)

- Clean up iomem resource handling in the Arm CMN driver

- Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}

MPAM (Memory Partitioning And Monitoring):

- Add architecture context-switch and hiding of the feature from KVM

- Add interface to allow MPAM to be exposed to user-space using
resctrl

- Add errata workaround for some existing platforms

- Add documentation for using MPAM and what shape of platforms can
use resctrl

Miscellaneous:

- Check DAIF (and PMR, where relevant) at task-switch time

- Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
(only relevant to asynchronous or asymmetric tag check modes)

- Remove a duplicate allocation in the kexec code

- Remove redundant save/restore of SCS SP on entry to/from EL0

- Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap
descriptions

- Add kselftest coverage for cmpbr_sigill()

Merge tag 'rust-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:

- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).

As proposed in LPC 2025 and the Maintainers Summit [1], we are
going to follow Debian Stable's Rust versions as our minimum
versions.

Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.

Other major distributions support a Rust version that is high
enough as well, including:

+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.

The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both
bumps, as well as documentation updates.

In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status'
enum used in Binder.

Link: https://lwn.net/Articles/1050174/ [1]

- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.

Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.

It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major
version, 'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled
for two architectures for now.

The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block
driver, it amounts to a 2%.

- Support global per-version flags.

While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler
version, i.e. in 'rust_common_flags', which sometimes is needed to
e.g. tweak the lints set per version.

Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.

- Support overriding the crate name and apply it to Rust Binder,
which wanted the module to be called 'rust_binder'.

- Add the remaining '__rust_helper' annotations (started in the
previous cycle).

'kernel' crate:

- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:

fn f<const N: usize>() {
const_assert!(N > 1);
}

fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}

In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.

Finally, improve the docs as well to clarify how these are
different from one another and how to pick the right one to use,
and their equivalence (if any) to the existing C ones for extra
clarity.

- 'sizes' module: add 'SizeConstants' trait.

This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the
hardware (e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.),
e.g.:

let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;

- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus
simplify the users in Tyr and PWM.

- 'ptr' module: add 'const_align_up'.

- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').

- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such
use in the 'task' module.

- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.

- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.

The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a
case of UB I noticed in 'regulator' that created a 'NonNull' on it.

Timekeeping:

- Expand the example section in the 'HrTimer' documentation.

- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.

- Add 'Delta::from_nanos()'.

'pin-init' crate:

- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.

- Improve feature gate handling for unstable features.

- Declutter the documentation of implementations of 'Zeroable' for
tuples.

- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.

rust-analyzer:

- Add type annotations to 'generate_rust_analyzer.py'.

- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').

- Refactor 'generate_rust_analyzer.py' to explicitly identify host
and target crates, improve readability, and reduce duplication.

And some other fixes, cleanups and improvements"

arm64: errata: Work around early CME DVMSync acknowledgement

C1-Pro acknowledges DVMSync messages before completing the SME/CME
memory accesses. Work around this by issuing an IPI to the affected CPUs
if they are running in EL0 with SME enabled.

Note that we avoid the local DSB in the IPI handler as the kernel runs
with SCTLR_EL1.IESB=1. This is sufficient to complete SME memory
accesses at EL0 on taking an exception to EL1. On the return to user
path, no barrier is necessary either. See the comment in
sme_set_active() and the more detailed explanation in the link below.

To avoid a potential IPI flood from malicious applications (e.g.
madvise(MADV_PAGEOUT) in a tight loop), track where a process is active
via mm_cpumask() and only interrupt those CPUs.

regulator: fix OF node imbalance on reuse

Johan Hovold <johan@kernel.org> says:

These drivers reuse the OF node of their parent multi-function device
but fail to take another reference to balance the one dropped by the
platform bus code when unbinding the MFD and deregistering the child
devices.

Fix this by using the intended helper for reusing OF nodes.

Note that the first two patches will cause a trivial conflict with Doug's
series adding accessor functions for struct device flags which has now been
merged to the driver-core tree:

Merge patch series "rust: bump minimum Rust and `bindgen` versions"

As proposed in the past in e.g. LPC 2025 and the Maintainers Summit [1],
we are going to follow Debian Stable's Rust versions as our minimum
supported version.

Debian Trixie was released with a Rust 1.85.0 toolchain [2], which it
still uses to this day [3] (i.e. no update to Rust 1.85.1).

Debian Trixie was released with `bindgen` 0.71.1, which it also still
uses to this day [4].

Debian Trixie's release happened on 2025-08-09 [5], which means that a
fair amount of time has passed since its release for kernel developers
to upgrade.

Thus bump the minimum to the new versions, i.e.

- Rust: 1.78.0 -> 1.85.0
- bindgen: 0.65.1 -> 0.71.1

There are a few main parts to the series, in this order:

- A few cleanups that can be performed before the bumps.
- The Rust bump (and its cleanups).
- The `bindgen` bump (and its cleanups).
- Documentation updates.
- The `cfi_encoding` patch, added here, which needs the bump.
- The per-version flags support and a Clippy cleanup on top.

rust: simplify `RUSTC_VERSION` Kconfig conditions

With the Rust version bump in place, several Kconfig conditions based on
`RUSTC_VERSION` are always true.

Thus simplify them.

The minimum supported major LLVM version by our new Rust minimum version
is now LLVM 18, instead of LLVM 16. However, there are no possible
cleanups for `RUSTC_LLVM_VERSION`.
