rust: docs: fix logo replacement

2023-10-19T14:40:00Z

The static files placement by `rustdoc` changed in Rust 1.67.0 [1], but the custom code we have to replace the logo in the generated HTML files did not get updated. Thus update it to have the Linux logo again in the output. Hopefully `rustdoc` will eventually support a custom logo from a local file [2], so that we do not need to maintain this hack on our side.

kbuild: remove old Rust docs output path

2023-10-19T14:39:44Z

The Rust code documentation output path moved from `rust/doc` to `Documentation/output/rust/rustdoc`. The `make cleandocs` target takes care of cleaning it now since it is integrated with the rest of the documentation. Thus remove the old reference.

rust: fix bindgen build error with fstrict-flex-arrays

2023-10-12T20:58:52Z

Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") enabled '-fstrict-flex-arrays=3' globally, but bindgen does not recognized this compiler option, triggering the following build error: error: unknown argument: '-fstrict-flex-arrays=3', err: true [ Miguel: Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") did it so only conditionally (i.e. only if the C compiler supports it). This explains what Andrea was seeing: he was compiling with a modern enough GCC, which enables the option, but with an old enough Clang. Andrea confirmed this was the case: he was using Clang 14 with GCC 13; and that Clang 15 worked for him. While it is possible to construct code (see mailing list for an example I came up with) where this could break, it is fairly contrived, and anyway GCC-built kernels with Rust enabled should only be used for experimentation until we get support for `rustc_codegen_gcc` and/or GCC Rust. So let's add this for the time being in case it helps somebody. ] Add '-fstrict-flex-arrays' to the list of cflags that should be ignored by bindgen.

A mistake was made and the description of `ECHILD` is wrong (it reuses the description of `ENOEXEC`). This fixes it to reflect what's in `errno-base.h`.
