* [PATCH] powerpc/smp: Add __init to init_big_cores()
From: Cédric Le Goater @ 2020-12-21 7:41 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Cédric Le Goater, Gautham R . Shenoy
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"")
