Subject: [PATCH 5.10 502/717] powerpc/smp: Add __init to init_big_cores()

From: Cédric Le Goater <clg@...d.org>

[ 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.

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