Steven Rostedt (Google) 8f3e665965 ring-buffer: Save text and data locations in mapped meta data 
When a ring buffer is mapped to a specific address, save the address of a
text function and some data. This will be used to determine the delta
between the last boot and the current boot for pointers to functions as
well as to data.
