Mark, I hope you don't me tagging you here. You were involved in the original issue and I hope you might be more comfortable reviewing this.

This updates the `openssl` and `openssl-sys` crates to support building
the toolchain with system libraries up to OpenSSL 3.0.0. This does not
affect the static version used via `openssl-src` in CI builds.

Say "this enum variant takes"/"this struct takes" instead of "this function takes"
This makes error messages for functions with incorrect argument counts adapt if they refer to a struct or enum variant:
```
error[E0061]: this enum variant takes 1 argument but 0 arguments were supplied
--> $DIR/struct-enum-wrong-args.rs:7:13
|
LL | let _ = Ok();
| ^^-- supplied 0 arguments
| |
| expected 1 argument
error[E0061]: this struct takes 1 argument but 0 arguments were supplied
--> $DIR/struct-enum-wrong-args.rs:8:13
|
LL | let _ = Wrapper();
| ^^^^^^^-- supplied 0 arguments
| |
| expected 1 argument
```
Fixes#86481.
Add regression test for issue #54685Closes#54685
Took the test from #54685 and modified it a bit to use assertion. Made sure that the updated test catches the original issue on 1.50 by running on Compiler Explorer (https://godbolt.org/z/E64onYeT5).
Resolve type aliases to the type they point to in intra-doc links
This feels a bit sketchy, but I think it's better than just rejecting the link.
Helps with #86120, r? ``@jyn514``
Allow to pass arguments to rustdoc-gui tool
Very convenient for testing. This is another part of https://github.com/rust-lang/rust/pull/86293

Add `io::Cursor::{remaining, remaining_slice, is_empty}`
Tracking issue: #86369
I came across an inconvenience when answering the following [Stack Overflow](https://stackoverflow.com/questions/67831170) question.
To get the remaining slice you have to call `buff.fill_buf().unwrap()`. Which in my opinion doesn't really tell you what is returned (in the context of Cursor). To improve readability and convenience when using Cursor i propose adding the method `remaining`.
The next thing i found inconvenient (unnecessary long) was detecting if the cursor reached the end. There are a few ways this can be achieved right now:
- `buff.fill_buf().unwrap().is_empty()`
- `buff.position() >= buff.get_ref().len()`
- `buff.bytes().next().is_none()`
Which all seem a bit unintuitive, hidden in trait documentations or just a bit long for such a simple task.
Therefor i propose another method called `is_empty`, maybe with another name, since this one may leave room for interpretation on what really is empty (the underlying slice, the remaining slice or maybe the position).
Since it seemed easier to create this PR instead of an RFC i did that, if an RFC is wanted, i can close this PR and write an RFC first.
Move `available_concurrency` implementation to `sys`
This splits out the platform-specific implementation of `available_concurrency` to the corresponding platforms under `sys`. No changes are made to the implementation.
Tidy didn't lint against this code being originally added outside of `sys` because of a bug (see #84677), this PR also reverts the exclusion that was introduced in that bugfix.
Tracking issue of `available_concurrency`: #74479
Add MIR pass to lower call to `core::slice::len` into `Len` operand
During some larger experiment with range analysis I've found that code like `let l = slice.len()` produces different MIR then one found in bound checks. This optimization pass replaces terminators that are calls to `core::slice::len` with just a MIR operand and Goto terminator.
It uses some heuristics to remove the outer borrow that is made to call `core::slice::len`, but I assume it can be eliminated, just didn't find how.
Would like to express my gratitude to `@oli-obk` who helped me a lot on Zullip
Fix rust.css fonts.
The `rust.css` file (used for all non-rustdoc and non-mdbook pages) has gotten out of sync with rustdoc's css. The two share the same fonts, so this updates them to match what rustdoc uses.
It would be ideal not to need this at all, but that's for another time.
Fix CI to fetch master on beta channel
This forward-ports a fix from the beta channel (landing in #86413, hopefully) to master so that we don't need to apply it on each round of backports.
This bug also demonstrates that our channel-checking is a bit insufficient -- stable is checked, but beta has some of its own peculiarities currently and isn't checked. But this does not attempt to adjust for that; we likely can't afford to run both beta and stable channels by CI and the current state here seems OK for now.

rustfmt: load nested out-of-line mods correctly
This should address https://github.com/rust-lang/rustfmt/issues/4874
r? `@Mark-Simulacrum`
Decided to make the change directly in tree here for expediency/to minimize any potential backporting issues, and because there's some subtree sync items I need to get resolved before pulling from r-l/rustfmt
Rustfix update
This updates to rustfix 0.6.0. One of the key changes here is https://github.com/rust-lang/rustfix/pull/195 which changes rustfix to apply multi-part suggestions. One of the tests needs to updated because there are some overlapping suggestions which rustfix cannot handle. The solution is to only apply the machine-applicable suggestions to avoid the overlapping issue.
This also includes a minor change to compiletest to provide better error messages with rustfix.
