From 95b5baf81001a80a8dd8b35306694db163bcb423 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Fri, 21 Apr 2023 09:11:26 -0700 Subject: MIPS: Mark check_bugs() as __init After commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"), a compiler may choose not to inline a function marked with just 'inline'. If check_bugs() is not inlined into start_kernel(), which occurs when building with clang after commit 9ea7e6b62c2b ("init: Mark [arch_call_]rest_init() __noreturn"), modpost complains with: WARNING: modpost: vmlinux.o: section mismatch in reference: check_bugs (section: .text) -> check_bugs32 (section: .init.text) check_bugs() is only called from start_kernel(), which itself is marked __init, so there would not be any issues at run time. Make it obvious to modpost that this call chain is safe by marking check_bugs() as __init, which fixes the warning.
