Hi Laurence,
Let's make this into more of a complete patch.
a. update the diffstat to include the Documentation change
b. send the patch with the Documentation change as part of the same patch, not as a separate patch (It looks like the multiple "---" lines in the email are confusing.)
c. send the patch to someone who can merge it: scripts/get_maintainer.pl top suggestions are: Thomas Gleixner <tglx@linutronix.de> or Ingo Molnar <mingo@kernel.org>
thanks, -- ~Randy
