This commit moves the ->reschedule_jiffies, ->reschedule_count, and ->work fields from the srcu_struct structure to the srcu_usage structure to reduce the size of the former in order to improve cache locality. However, this means that the container_of() calls cannot get a pointer to the srcu_struct because they are no longer in the srcu_struct. This issue is addressed by adding a ->srcu_ssp field in the srcu_usage structure that references the corresponding srcu_struct structure. And given the presence of the sup pointer to the srcu_usage structure, replace some ssp->srcu_usage-> instances with sup->.
