tracing/ftrace: adapt the boot tracer to the new print_line type
This patch adapts the boot tracer to the new type of the print_line callback. It still relays entries it doesn't support to default output functions. Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Acked-by: Pekka Paalanen <pq@iki.fi> Signed-off-by: Ingo Molnar <mingo@elte.hu>
