linux-kselftest-4.14-rc1-update 

This update consists of:
 
 -- TAP13 framework API and converting tests to TAP13 continues. A few
    more tests are converted and kselftest common RUN_TESTS in lib.mk
    is enhanced to print TAP13 to cover test shell scripts that won't
    be able to use kselftest API.
 
 -- Several fixes to existing tests to not fail in unsupported cases.
    This has been an ongoing work based on the feedback from stable
    release kselftest users.
 
 -- A new watchdog test and much needed cleanups to the existing tests
    from Eugeniu Rosca.
 
 -- Changes to kselftest common lib.mk framework to make RUN_TESTS a
    function to be called from individual test make files to run stress
    and destructive sub-tests.
