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.") # Cc: stable@vger.kernel.org # v3.14 # Signed-off-by: Joel Stanley # Acked-by: Gautham R.
