- Fix several issues with the 'rustc-option' macro. It includes a
refactor from Masahiro of three '{cc,rust}-*' macros, which is not
a fix but avoids repeating the same commands (which would be
several lines in the case of 'rustc-option').

includes the addition of 'CONFIG_RUSTC_LLVM_VERSION', which is not
a fix but is needed for the actual fix.

kbuild: rust: add `CONFIG_RUSTC_LLVM_VERSION`

Each version of Rust supports a range of LLVM versions. There are cases where
we want to gate a config on the LLVM version instead of the Rust version.
Normalized cfi integer tags are one example [1].

The invocation of rustc-version is being moved from init/Kconfig to
scripts/Kconfig.include for consistency with cc-version.

Merge tag 'rust-6.12' of https://github.com/Rust-for-Linux/linux

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.

MAINTAINERS:

- Trevor is joining as reviewer of the "RUST" entry.

kbuild: rust: Define probing macros for rustc

Creates flag probe macro variants for `rustc`. These are helpful
because:

1. The kernel now supports a minimum `rustc` version rather than a
single version.
2. `rustc` links against a range of LLVM revisions, occasionally even
ones without an official release number. Since the availability of
some Rust flags depends on which LLVM it has been linked against,
probing is necessary.
