a4a0342cf5 ci: disabled: riscv: work around QEMU regression
This bumps the version of the bbl bootloader not to perform 64-bit
accesses to the PLIC. Doing so resulted in the QEMU test machine to fail
to boot:

bbl loader
../machine/mtrap.c:21: machine mode: unhandlable trap 7 @ 0x0000000080001f6e

bootstrap: always use the Rust version in package names
The format of the tarballs produced by CI is roughly the following:

    {component}-{release}-{target}.{ext}

While on the beta and nightly channels `{release}` is just the channel
name, on the stable channel is either the Rust version or the version of
the component we're shipping:

    cargo-0.47.0-x86_64-unknown-linux-gnu.tar.xz
    clippy-0.0.212-x86_64-unknown-linux-gnu.tar.xz
    llvm-tools-1.46.0-x86_64-unknown-linux-gnu.tar.xz
    miri-0.1.0-x86_64-unknown-linux-gnu.tar.xz
    rls-1.41.0-x86_64-unknown-linux-gnu.tar.xz
    rust-1.46.0-x86_64-unknown-linux-gnu.tar.xz
    ...

This makes it really hard to get the package URL without having access
to the manifest (and there is no manifest on ci-artifacts.rlo), as there
is no consistent version number to use.

This commit addresses the problem by always using the Rust version
number as `{release}` for the stable channel, regardless of the version
number of the component we're shipping. I chose that instead of "stable"
to avoid breaking the URL scheme *that* much.

Rustup should not be affected by this change, as it fetches the URLs
from the manifest. Unfortunately we don't have a way to test other
clients before making a stable release, as this change only affects the
stable channel.

The following PR was reverted, so I've ignored it too:

~~Also, I took the liberty of adding a "Thanks" section, naming all the contributors to this release. I think they deserve visibility in the changelog. Please tell me if we want to add this or maybe it's redundant given we link to the PRs?~~

4c765f66a4 Allow generic parameters in intra-doc links
The contents of the generics will be mostly ignored (except for warning
if fully-qualified syntax is used, which is currently unsupported in
intra-doc links - see issue #74563).

* Allow links like `Vec<T>`, `Result<T, E>`, and `Option<Box<T>>`
* Allow links like `Vec::<T>::new()`
* Warn on
  * Unbalanced angle brackets (e.g. `Vec<T` or `Vec<T>>`)
  * Missing type to apply generics to (`<T>` or `<Box<T>>`)
  * Use of fully-qualified syntax (`<Vec as IntoIterator>::into_iter`)
  * Invalid path separator (`Vec:<T>:new`)
  * Too many angle brackets (`Vec<<T>>`)
  * Empty angle brackets (`Vec<>`)

Note that this implementation *does* allow some constructs that aren't
valid in the actual Rust syntax, for example `Box::<T>new()`. That may
not be supported in rustdoc in the future; it is an implementation
detail.

Resolve intra-doc links on additional documentation for re-exports in lexical scope

Fixes https://github.com/rust-lang/rust/issues/77254.

- Preserve the parent module of `DocFragment`s
  + Add `parent_module` to `DocFragment`
  + Require the `parent_module` of the item being inlined
  + Preserve the hir_id for ExternCrates so rustdoc can find the parent module later
  + Take an optional `parent_module` for `build_impl` and `merge_attrs`.
    Preserve the difference between parent modules for each doc-comment.
  + Support a single additional re-exports in from_ast. Originally this took a vec but I ended up not using it.
  + Don't require the parent_module for all `impl`s, just inlined items

    In particular, this will be `None` whenever the attribute is not on a
    re-export.

  + Only store the parent_module, not the HirId

    When re-exporting a re-export, the HirId is not available. Fortunately,
    `collect_intra_doc_links` doesn't actually need all the info from a
    HirId, just the parent module.

- Introduce `Divider`

  This distinguishes between documentation on the original from docs on  the re-export.

- Use the new module information for intra-doc links

  + Make the parent module conditional on whether the docs are on a re-export
  + Make `resolve_link` take `&Item` instead of `&mut Item`

    Previously the borrow checker gave an error about multiple mutable
    borrows, because `dox` borrowed from `item`.

  + Fix `crate::` for re-exports

    `crate` means something different depending on where the attribute
    came from.

  + Make it work for `#[doc]` attributes too

    This required combining several attributes as one so they would keep
    the links.

clippy_lints: Do not warn against Box parameter in C FFI

changelog: [`boxed_local`]: don't lint in `extern fn` arguments

Fixes #5542.

When using C FFI, to handle pointers in parameters it is needed to
declare them as `Box` in its Rust-side signature. However, the current
linter warns against the usage of Box stating that "local variable
doesn't need to be boxed here".

This commit fixes it by ignoring functions whose Abi is C.

The cvt function compares the argument with -1 and when equal returns a new
io::Error constructed from errno. It is used together posix_spawn_* functions.
This is incorrect. Those functions do not set errno. Instead they return
non-zero error code directly.

Check for non-zero return code and use it to construct a new io::Error.

265e4841b7 Auto merge of #6117 - dtolnay:string_lit_as_bytes, r=ebroto
Downgrade string_lit_as_bytes to nursery

Between #1402 (regarding `to_owned`) and #4494 (regarding `impl Read`), as well as other confusion I've seen hit in my work codebase involving string_lit_as_bytes (`"...".as_bytes().into()`), I don't think this lint is at a quality to be enabled by default.

I would consider re-enabling this lint after it is updated to understand when the surrounding type information is sufficient to unsize `b"..."` to &\[u8\] without causing a type error.

As currently implemented, this lint is pushing people to write `&b"_"[..]` which is not an improvement over `"_".as_bytes()` as far as I am concerned.

Add compile fail test for issue 27675

A recently merged PR (#73905) strengthened the checks on bounds of associated items. This rejects the attack path of #27675 which consisted of constructing a `dyn Trait<Item=T>` where `T` would not fulfill the bounds required on `Item` of the `Trait` behind the dyn object.

This regression test, extracted from [the weaponized instance](https://github.com/rust-lang/rust/issues/27675#issuecomment-696956878), checks that this is rejected.

(docs): make mutex error comment consistent with codebase

Although exceptionally minor, I found this stands out from other error reporting language used in doc comments. With the existence of the `failure` crate, I suppose this could be slightly ambiguous. In any case, this change brings the particular comment into a consistent state with other mentions of returning errors.

BTreeMap: comment why drain_filter's size_hint is somewhat pessimistic

The `size_hint` of the `DrainFilter` iterator doesn't adjust as you iterate. This hardly seems important to me, but there has been a comparable PR #64383 in the past. I guess a scenario is that you first iterate half the map manually and keep most of the key/value pairs in the map, and then tell the predicate to drain most of the key/value pairs and `.collect` the iterator over the remaining half of the map.

I am totally ambivalent whether this is better or not.
