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

There was also a conflict with some of Andrew's new userfaultfd tests.

I'm not at all sure I merged that correctly, although I tried to make
the resolution at least look sane. The odd thing about those new tests
is that it's all the same source file, except built with different
compile-time defines to be different test binaries.

I didn't find any way to do that with any standard selftest makefile
magic, so I just did the build rules by hand.

Somebody should actually verify that it does the right thing, please..
Adding the two Mike's that did those test additions to the participant
list.

The userfaultfd_* tests are built and they are working just fine.
Maybe it's worth adding userfaultfd_{hugetlb,shmem}.c which will define the
required defines and include userfaultfd.c?
Than we can get away with only specifying LDFLAGS += -lpthread in the
Makefile.

Thanks Mike,  I also verified that the tests build/run as they should.

I started the current scheme when adding support for hugetlbfs, which I
thought would be a 'one off'.  Did not know about the shmem work that was
in progress.

Another option is to only have a single userfaultfd executable and pass
an option (anon, hugetlb, shmem ...) that indicates the type of pages/mapping
to test.

In any case, the makefile modifications work so this is not urgent.  Perhaps
we can discuss with Andrea and figure out what would be the best scheme
moving forward.

Hello,

That sounds good to me. I guess it was quicker and it generated more
compact diffs to differentiate based on #ifdefs initially, but it
makes sense to unify those binaries into one now, as we don't mind the
size of the selftest executable. run_vmtests takes custom parameters
already, it will just take one more then.

Thanks,
Andrea
