sched: avoid CPUs with high irq activity for non-small tasks
The irq-aware scheduler is to achieve better performance by avoiding task
placement to the CPUs which have high irq activity. However current
scheduler places tasks to the CPUs which are loaded by irq activity
preferably as opposed to what it is meant to be when the task is non-small.
This is suboptimal for both power and performance.
Fix task placement algorithm to avoid CPUs with significant irq activities.
