Linus,

ftrace updates for 7.1:

- 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.
