Subject: [PATCH] powerpc/smp: Make some symbols static
References: jsc#SLE-13615 bsc#1180100 ltc#190257 git-fixes
Patch-mainline: v5.13-rc1
Git-commit: 078277acbd7c3fdb25c01a3cd5b4a1a875a1ab2f
The sparse tool complains as follows:
arch/powerpc/kernel/smp.c:86:1: warning:
symbol '__pcpu_scope_cpu_coregroup_map' was not declared. Should it be static?
arch/powerpc/kernel/smp.c:125:1: warning:
symbol '__pcpu_scope_thread_group_l1_cache_map' was not declared. Should it be static?
arch/powerpc/kernel/smp.c:132:1: warning:
symbol '__pcpu_scope_thread_group_l2_cache_map' was not declared. Should it be static?
These symbols are not used outside of smp.c, so this
commit marks them static.
