rcu: Avoid invoking RCU core on offline CPUs Offline CPUs transition through the scheduler to the idle loop one last time before being shut down. This can result in RCU raising softirq on this CPU, which is at best useless given that the CPU's callbacks will be offloaded at CPU_DEAD time. This commit therefore avoids raising softirq on offline CPUs. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
