| Subject: [PATCH] CPUFREQ: Loongson2: drop set_cpus_allowed_ptr() |
| |
| It is pure mystery to me why we need to be on a specific CPU while |
| looking up a value in an array. |
| My best shot at this is that before commit d4019f0a92ab ("cpufreq: move |
| freq change notifications to cpufreq core") it was required to invoke |
| cpufreq_notify_transition() on a special CPU. |
| |
| Since it looks like a waste, remove it. |
