Max Filippov dac518bbce xtensa: fix stop_machine_cpuslocked call in patch_text ...

commit f406f2d03e 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.
