  "A couple of warning fixes:

  Two fixes from Peter Oberparleiter <oberpar@linux.ibm.com>:
    Commit 6b7dca40 ("tracing: Allow gcov profiling on only ftrace subsystem")
   uncovered linker problems when using gcov kernel profiling on some
   architectures. These problems were likely introduced earlier, and are
   possibly related to compiler changes."
