Keeping a track of the load footprint of each task on every CPU that it executed on gives the scheduler much more flexibility in terms of the number of frequency guidance policies. These new fields will be used in subsequent patches as we alter the load fixup mechanism upon task migration. We still need to maintain the curr/prev_window sums as they will also be required in subsequent patches as we start to track top tasks based on cumulative load. Also, we need to call init_new_task_load() for the idle task. This is an existing harmless bug as load tracking for the idle task is irrelevant. However, in this patch we are adding pointers to the ravg structure. These pointers have to be initialized even for the idle task. Finally move init_new_task_load() to sched_fork(). This was always the more appropriate place, however, following the introduction of new pointers in the ravg struct, this is necessary to avoid races with functions such as reset_all_task_stats().
