Merge tag 'linux-kselftest-4.13-rc1-update' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull Kselftest updates from Shuah Khan:
 "This update consists of:

   - TAP13 framework and changes to some tests to convert to TAP13.
     Converting kselftest output to standard format will help identify
     run to run differences and pin point failures easily. TAP13 format
     has been in use for several years and the output is human friendly.

     Please find the specification:
       https://testanything.org/tap-version-13-specification.html

     Credit goes to Tim Bird for recommending TAP13 as a suitable
     format, and to Grag KH for kick starting the work with help from
     Paul Elder and Alice Ferrazzi

     The first phase of the TAp13 conversion is included in this update.
     Future updates will include updates to rest of the tests.

   - Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.

   - Kselftest documnetation has been converted to ReST format. Document
     now has a new home under Documentation/dev-tools.

   - kselftest_harness.h is now available for general use as a result of
     Mickaël Salaün's work.

   - Several fixes to skip and/or fail tests gracefully on older
     releases"
