xtensa: fix stop_machine_cpuslocked call in patch_text
commitf406f2d03e
upstream. patch_text must invoke patch_text_stop_machine on all online CPUs, but it calls stop_machine_cpuslocked with NULL cpumask. As a result only one CPU runs patch_text_stop_machine potentially leaving stale icache entries on other CPUs. Fix that by calling stop_machine_cpuslocked with cpu_online_mask as the last argument.
