Merge tag 'linux-kselftest-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull kselftest update from Shuah Khan:
 "This update adds two new test suites: futex and seccomp.

  In addition, it includes fixes for bugs in timers, other tests, and
  compile framework.  It introduces new quicktest feature to enable
  users to choose to run tests that complete in a short time"
