arm64: cpu_ops: Add missing 'const' qualifiers
Building the kernel with an LTO-enabled GCC spits out the following "const" warning for the cpu_ops code: 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 = { Fix it by adding missed const qualifiers.
