Starting with Rust 1.99.0 (expected 2026-10-01), under
`CONFIG_RUST_DEBUG_ASSERTIONS=y`, `objtool` may report:
rust/kernel.o: warning: objtool: _R..._6kernel12module_param9set_paramaEB4_()
falls through to next function _R..._6kernel12module_param9set_paramhEB4_()
(and many others) due to calls to the `noreturn` symbol [1]:
core::panicking::panic_null_reference_constructed
Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.
See commit 56d680dd23 ("objtool/rust: list `noreturn` Rust functions")
for more details.
