One nitpick below..

The default value of this option is little complex.  I think we need
to add following paragraph:

		If this option is not set and report.children or top.children is
		set to true (or the equivalent command line option is given),
		the default value of this option is changed to 'caller' for the
		execution of 'perf report' or 'perf top'.  Other commands will
		still default to 'callee'.

Thanks,
Namhyung
