There's inconsistency in variable declaration and section type. GCC doesn't
throw error for usual build. But if LTO enabled, build becomes broken, like
this:
mm/percpu.c:2168:20: error: pcpu_fc_names causes a section type conflict
with dt_supported_cpu_ops
const char * const pcpu_fc_names[PCPU_FC_NR] __initconst = {
^
arch/arm64/kernel/cpu_ops.c:34:37: note: ‘dt_supported_cpu_ops’ was declared here
static const struct cpu_operations *dt_supported_cpu_ops[] __initconst = {
And so on. Fix it by adding missed const qualifiers.
v2: more details in patch description.
