Merge tag 'linux-kselftest-4.14-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull kselftest fixes from Shuah Khan:
"This update consists of:
- fixes to several existing tests
- a test for regression introduced by b9470c27607b ("inet: kill
smallest_size and smallest_port")
- seccomp support for glibc 2.26 siginfo_t.h
- fixes to kselftest framework and tests to run make O=dir use-case
- fixes to silence unnecessary test output to de-clutter test results"
