#     powerpc: Make cpu_spec __ro_after_init
#     
#     The cpu_spec is a struct holding various information about the CPU the
#     kernel is executing on. It's populated early in boot and must not change
#     after that.
#     
#     In particular the cpu_features and mmu_features hold the set of
#     discovered CPU/MMU features and are used to set static keys for each
#     feature, and do binary patching of assembly. So any change to the
#     cpu_features/mmu_features later in boot will not be reflected in
#     the state of the static keys or patched code.
#     
#     There is already logic to check that cpu_features/mmu_features don't
#     change, see check_features() in feature-fixups.c.
#     
#     But as another layer of protection the entire cpu_spec should be read
#     only after init, annotate it as such.
