# \[PATCH v2 15/27\] x86/xen: Ignore noreturn status of weak mem\_map\_via\_hcall() - From: Josh Poimboeuf \ - Date: 2026-09-08 20:34:36 - List: rust-for-linux - Page: https://ratatoskr.run/rust-for-linux/2026/09/17533671 - Thread: https://ratatoskr.run/rust-for-linux/2026/09/17533657/t.md ```text Unlike the non-weak version, the weak version of mem_map_via_hcall() doesn't return. Tell objtool to ignore that, as the protoype (and the non-weak version) aren't noreturn so its callers can't assume it.
