sched/topology, drivers/base/arch_topology: Rebuild the sched_domain hierarchy when capacities change The setting of SD_ASYM_CPUCAPACITY depends on the per-CPU capacities. These might not have their final values when the hierarchy is initially built as the values depend on cpufreq to be initialized or the values being set through sysfs. To ensure that the flags are set correctly we need to rebuild the sched_domain hierarchy whenever the reported per-CPU capacity (arch_scale_cpu_capacity()) changes. This patch ensure that a full sched_domain rebuild happens when CPU capacity changes occur.
