Merge tag 'linux-kselftest-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel...

Pull kselftest update from Shuah Khan:
 "This Kselftest update for 4.17-rc1 consists of:

   - Test build error fixes

   - Fixes to prevent intel_pstate from building on non-x86 systems.

   - New test for ion with vgem driver.

   - Change to print the test name to /dev/kmsg to add context to kernel
     failures if any uncovered from running the test.

   - Kselftest framework enhancements to add KSFT_TAP_LEVEL environment
     variable to prevent nested TAP headers being printed in the
     Kselftest output.

     Nested TAP13 headers could cause problems for some parsers. This
     change suppresses the nested headers from test programs and test
     shell scripts with changes to framework and Makefiles without
     changing the tests"
