[GIT PULL] Kselftest update for 4.11-rc1
From: Shuah Khan
Date: Fri Feb 24 2017 - 16:20:01 EST
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
