#     powerpc: Warn about use of smt_snooze_delay
#     
#     It's not done anything for a long time. Save the percpu variable, and
#     emit a warning to remind users to not expect it to do anything.
#     
#     This uses pr_warn_once instead of pr_warn_ratelimit as testing
#     'ppc64_cpu --smt=off' on a 24 core / 4 SMT system showed the warning
#     to be noisy, as the online/offline loop is slow.
#     
#     Fixes: 3fa8cad82b94 ("powerpc/pseries/cpuidle: smt-snooze-delay cleanup.")
