a189df12bd Clippy: HACK! Fix bootstrap error 
This will be removed in the next sync, once beta is at 1.52. Until then
this hack avoids to put `cfg(bootstrap)` into Clippy.

2547edb842 wrong_self_convention: fix lint in case of to_*_mut method 
When a method starts with `to_` and ends with `_mut`, it should expect a `&mut self` parameter,
otherwise `&self`.

a1e25a957e Auto merge of #6794 - camsteffen:needless-borrowed-ref, r=flip1995 
Improve needless_borrowed_ref docs

changelog: none

I think "borrowed ref" is a confusing description for this lint. Destructuring a reference is the opposite of borrowing. So I updated the wording throughout the docs. Unfortunately this nit applies to the name of the lint itself, but I won't bother changing that. One motivation for these changes is to clarify the difference between this lint and `needless_borrow` (they are actually quite different). Let me know if I need to clarify anything or if you disagree with any changes.

59750dceb8 upper_case_acronyms: add optional aggressive mode and relax default 
Moves the lint back from pedantic to style group.
The lint default now only warns on names that are completely capitalized, like "WORD"
and only if the name is longer than 2 chars (so that names where each of the letter represents a word are still distinguishable).
For example: FP (false positive) would still be "valid" and not warned about (but EOF would warn).

A "upper_case_acronyms_aggressive: true/false" config option was added that restores the original lint behaviour to warn
on any kind of camel case name that had more than one capital letter following another capital letter.

0eefa6169d upper_case_acronyms: move lint from style to pedantic lint group

Fix FP in inherent_to_string when the function has generic parameters

Minimal example of the false positive:
````
struct G;

impl G {
    fn to_string<const _N: usize>(&self) -> String {
        "G.to_string()".to_string()
    }
}

fn main() {
    let g = G;
    g.to_string::<1>();
}
````
Clippy emits an `inherent_to_string` warning, and suggests that we implement `Display` for `G` instead. However, this is not possible, since the generic parameter _N only exists in this function, not in `G` itself. This particular example uses const generics, which is where the issue is most likely to come up, but this PR skips the lint if the `to_string` function has any kind of generic parameters.

Teach SpanlessEq binding IDs

changelog: Fix collapsible_match false positive

Fixes #6740

This PR changes the way `SpanlessEq` determines whether two local variables are the same. Instead of checking that the names match, it checks that the `HirId`s match. If local bindings are declared within the expressions that are being compared, `SpanlessEq` will remember bindings that correspond to each other in a `FxHashMap<HirId, HirId>`. This makes `SpanlessEq` more flexible while also fixing false positives.

Example: `{ let x = 1; x + 2 }` is equal to `{ let y = 1; y + 2 }`.

CC `@xFrednet` I think this will resolve some concerns in #6463

ast: Keep expansion status for out-of-line module items

I.e. whether a module `mod foo;` is already loaded from a file or not.
This is a pre-requisite to correctly treating inner attributes on such modules (https://github.com/rust-lang/rust/issues/81661).

With this change AST structures for `mod` items diverge even more for AST structure for the crate root, which previously used `ast::Mod`.
Therefore this PR removes `ast::Mod` from `ast::Crate` in the first commit, these two things are sufficiently different from each other, at least at syntactic level.
Customization points for visiting a "`mod` item or crate root" were also removed from AST visitors (`fn visit_mod`).
`ast::Mod` itself was refactored away in the second commit in favor of `ItemKind::Mod(Unsafe, ModKind)`.

New lint: default_numeric_fallback

fixes #6064
r? `@flip1995`

As we discussed in [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20.236064/near/224647188) and [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20clippy.236064/near/224746333),   I start implementing this lint from the strictest version.
In this PR, I'll allow the below two cases to pass the lint to reduce FPs.

1. Appearances of unsuffixed numeric literals in `Local` if `Local` has a type annotation, for example:
```rust
// Good.
let x: i32 = 1;

// Also good.
let x: (i32, i32) = if cond {
   (1, 2)
} else {
   (2, 3)
};
```

2. Appearances of unsuffixed numeric literals in args of `Call` or `MethodCall`  if corresponding arguments of their signature have concrete types, for example:
```rust
fn foo_mono(x: i32) -> i32 {
    x
}

fn foo_poly<T>(t: T) -> t {
    t
}

// Good.
let x = foo_mono(13);

// Still bad.
let x: i32 = foo_poly(13);
```

ce0a47ab8c Auto merge of #81238 - RalfJung:copy-intrinsics, r=m-ou-se 
directly expose copy and copy_nonoverlapping intrinsics

This effectively un-does https://github.com/rust-lang/rust/pull/57997. That should help with `ptr::read` codegen in debug builds (and any other of these low-level functions that bottoms out at `copy`/`copy_nonoverlapping`), where the wrapper function will not get inlined. See the discussion in https://github.com/rust-lang/rust/pull/80290 and https://github.com/rust-lang/rust/issues/81163.
