Subject: [PATCH] tracing: add annotation to what type of stack trace is
 recorded

The current method of printing out a stack trace is to add a new line
and print out the trace:

    yum-updatesd-3120  [002]   573.691303:
 => do_softirq
 => irq_exit
 => smp_apic_timer_interrupt
 => apic_timer_interrupt

This looks a bit awkward, and if we have both stack and user stack traces
running, it would be nice to have a title to tell them apart, although
it is easy to tell by the output.

This patch adds an annotation to the start of the stack traces:

            init-1     [003]   929.304979: <stack trace>
 => user_path_at
 => vfs_fstatat
 => vfs_stat
 => sys_newstat
 => system_call_fastpath

             cat-3459  [002]  1016.824040: <user stack trace>
 =>  <0000003aae6c0250>
 =>  <00007ffff4b06ae4>
 =>  <69636172742f6775>
