Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull two 'perf bench' fixes from Arnaldo:

  * Make 'perf bench mem' (i.e. no args) mean 'run all tests' so that we can run
    all tests, not stopping at the numa ones.  (Arnaldo Carvalho de Melo)

  * Fix NULL pointer dereference after last test in in "perf bench all" (Patrick Palka)
