[RFC PATCH 06/14] sched/cpufreq_sched: modify pcpu_capacity handling
From: Patrick Bellasi
Date: Wed Aug 19 2015 - 14:49:44 EST
From: Juri Lelli <juri.lelli@xxxxxxx>
Use the cpu argument of cpufreq_sched_set_cap() to handle per_cpu writes,
as the thing can be called remotely (e.g., from load balacing code).
