David S. Miller bd4352cadf sparc64: Fix bootup with mcount in some configs.
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.
