From c0f2077baa4113f38f008b8e912b9fb3ff8d43df Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Tue, 23 Nov 2021 08:04:34 +0100 Subject: x86/boot: Mark prepare_command_line() __init Fix: WARNING: modpost: vmlinux.o(.text.unlikely+0x64d0): Section mismatch in reference \ from the function prepare_command_line() to the variable .init.data:command_line The function prepare_command_line() references the variable __initdata command_line. This is often because prepare_command_line lacks a __initdata annotation or the annotation of command_line is wrong. Apparently some toolchains do different inlining decisions.
