Pull tracing fixes from Steven Rostedt:

 - Fix tp_printk command line option crashing the kernel

   With the code that can handle a buffer from a previous boot, the
   trace_check_vprintf() needed access to the delta of the address space
   used by the old buffer and the current buffer. To do so, the
   trace_array (tr) parameter was used. But when tp_printk is enabled on
   the kernel command line, no trace buffer is used and the trace event
   is sent directly to printk(). That meant the tr field of the iterator
   descriptor was NULL, and since tp_printk still uses
   trace_check_vprintf() it caused a NULL dereference.

 - Add ptrace.h include to x86 ftrace file for completeness

 - Fix rtla installation when done with out-of-tree build

 - Fix the help messages in rtla that were incorrect

 - Several fixes to fix races with the timerlat and hwlat code

   Several locking issues were discovered with the coordination between
   timerlat kthread creation and hotplug. As timerlat has callbacks from
   hotplug code to start kthreads when CPUs come online. There are also
   locking issues with grabbing the cpu_read_lock() and the locks within
   timerlat.
