Functions invoked early when booting up a cpu can't use tracing because mcount requires a valid 'current_thread_info()' and TLB mappings to be setup. The code path of sun4v_register_mondo_queues --> register_one_mondo is one such case. sun4v_register_mondo_queues already has the necessary 'notrace' annotation, but register_one_mondo does not. Normally register_one_mondo is inlined so the bug doesn't trigger, but with some config/compiler combinations, it won't be so we must properly mark it notrace. While we're here, add 'notrace' annoations to prom_printf and prom_halt so that early error handling won't have the same problem.
