Hi Linus,

Please pull the Kselftest update for 4.11-rc1

This update consists of:

-- fixes to several existing tests from Stafford Horne
-- cpufreq tests from Viresh Kumar
-- Selftest build and install fixes from Bamvor Jian Zhang
   and Michael Ellerman
-- Fixes to protection-keys tests from Dave Hansen
-- Warning fixes from Shuah Khan

Stephen saw a conflict during kselftest merge with next

between commit:

  d498f8719a09 ("bpf: Rebuild bpf.o for any dependency update")

from the net-next tree and commit:

  88baa78d1f31 ("selftests: remove duplicated all and clean target")

Stephen fixed this up in linux-next and volunteered to carry forward
the fix - fix diff attached. Please let me know if this isn't
acceptable. Sorry for the inconvenience.

Diff for the update attached.

thanks,
-- Shuah
