Subject: [PATCH] powerpc/smp: Add __init to init_big_cores()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch-mainline: v5.11-rc1
Git-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.

Fixes: 425752c63b6f ("powerpc: Detect the presence of big-cores via "ibm, thread-groups"")
