Steven Rostedt (Red Hat) 8573636ea7 ring-buffer: Use READ_ONCE() for most tail_page access 
As cpu_buffer->tail_page may be modified by interrupts at almost any time,
the flow of logic is very important. Do not let gcc get smart with
re-reading cpu_buffer->tail_page by adding READ_ONCE() around most of its
accesses.
