The rcu_boost_kthread_setaffinity() function is invoked at rcutree_online_cpu() and rcutree_offline_cpu() time, early in the online timeline and late in the offline timeline, respectively. It is also invoked from rcutree_dead_cpu(), however, in the absence of userspace manipulations (for which userspace must take responsibility), this call is redundant with that from rcutree_offline_cpu(). This redundancy can be demonstrated by printing out the relevant cpumasks This commit therefore removes the call to rcu_boost_kthread_setaffinity() from rcutree_dead_cpu().
