Merge tag 'trace-v4.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt...

Pull tracing fixes from Steven Rostedt:
 "Various bug fixes:

   - Two small memory leaks in error paths.

   - A missed return error code on an error path.

   - A fix to check the tracing ring buffer CPU when it doesn't exist
     (caused by setting maxcpus on the command line that is less than
     the actual number of CPUs, and then onlining them manually).

   - A fix to have the reset of boot tracers called by lateinit_sync()
     instead of just lateinit(). As some of the tracers register via
     lateinit(), and if the clear happens before the tracer is
     registered, it will never start even though it was told to via the
     kernel command line"
