#     powerpc/64e: Drop stale call to smp_processor_id() which hangs SMP startup
#     
#     Commit ebb9d30a6a74 ("powerpc/mm: any thread in one core can be the
#     first to setup TLB1") removed the need to know the cpu_id in
#     early_init_this_mmu(), but the call to smp_processor_id() which was
#     marked __maybe_used remained.
#     
#     Since commit ed1cd6deb013 ("powerpc: Activate CONFIG_THREAD_INFO_IN_TASK")
#     thread_info cannot be reached before MMU is properly set up.
#     
#     Drop this stale call to smp_processor_id() which makes SMP hang when
#     CONFIG_PREEMPT is set.
#     
#     Fixes: ebb9d30a6a74 ("powerpc/mm: any thread in one core can be the first to setup TLB1")
