Lets get rid of it. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Rafael J.

And their frequencies are always updated together. Many SMP system's cpufreq drivers take care of this in individual drivers but the best place for this code is in cpufreq core. This patch modifies cpufreq_notify_transition() to notify frequency change for all cpus in policy->cpus and hence updates all users of this API.

Almost change is trivial, most important change are to remove following like =operator. cpumask_t cpu_mask = *mm_cpumask(mm); cpus_allowed = current->cpus_allowed; Because cpumask_var_t is =operator unsafe. These usage might prevent kernel core improvement. No functional change. Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: David S.

Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.
