[GIT PULL] tracing: More updates for 7.2

[Steven Rostedt]

Linus,

More tracing updates for 7.2:

- Move non-trace_printk() functions into trace_controls.h

  Several tracing controls and output function prototypes were included in
  kernel.h. When trace_printk.h was created, all of them were moved from
  kernel.h into trace_printk.h. Several of those functions have nothing to
  do with trace_printk() but instead are used to start, stop tracing as
  well as trigger stack traces into the tracing buffer or dump it to the
  console. Create a new header called trace_controls.h and move these
  functions into that file from trace_printk.h.

- Remove the include of trace_printk.h from kernel.h.

  Instead of having trace_printk.h indirectly included in all files of the
  kernel for debugging purposes, require trace_printk.h to be included on
  a per file bases when it is needed. The locations in the kernel that
  reference trace_printk() now have a direct include of trace_printk.h.

Note, I applied and tested this on your latest commit from yesterday to
make sure it works and I didn't miss other possible use cases that needed
the includes.
