[PATCH 3/7] kernel: Avoid softlockups in stop_machine() during heavy printing

From: Jan Kara When there are lots of messages accumulated in printk buffer, printing them (especially over serial console) can take a long time (tens of seconds). stop_machine() will effectively make all cpus spin in multi_cpu_stop() waiting for the CPU doing printing to print all the messages
