6.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miguel Ojeda ojeda@kernel.org
commit cbeaa41dfe26b72639141e87183cb23e00d4b0dd upstream.
Developers are indeed hitting other of the `noreturn` slice symbols in Nova [1], thus relax the last check in the list so that we catch all of them, i.e.
*_4core5slice5index22slice_index_order_fail *_4core5slice5index24slice_end_index_len_fail *_4core5slice5index26slice_start_index_len_fail *_4core5slice5index29slice_end_index_overflow_fail *_4core5slice5index31slice_start_index_overflow_fail
These all exist since at least Rust 1.78.0, thus backport it too.
See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions") for more details.
