Pull ftrace update from Steven Rostedt:

 - Speed up ftrace_lookup_symbols() for single lookups

   The kallsyms lookup in ftrace_lookup_symbols() does a linear search
   over each symbol. This is fine when it must match multiple strings,
   but when there's only a single string being searched for, using a
   binary search is much more efficient. When a single string is passed
   in to search, use the binary search method.
