From: Cédric Le Goater <clg@xxxxxxxx> [ Upstream commit 9014eab6a38c60fd185bc92ed60f46cf99a462ab ] It fixes this link warning: WARNING: modpost: vmlinux.o(.text.unlikely+0x2d98): Section mismatch in reference from the function init_big_cores.isra.0() to the function .init.text:init_thread_group_cache_map() The function init_big_cores.isra.0() references the function __init init_thread_group_cache_map(). This is often because init_big_cores.isra.0 lacks a __init annotation or the annotation of init_thread_group_cache_map is wrong.
