[Greg Kroah-Hartman]

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Shuah Khan (Samsung OSG)" <sh...@kernel.org>

[ Upstream commit d2d49495b5c0dffee5c4da5ea12ac0da6679bd08 ]

Fix to return KSFT_SKIP when test couldn't be run because AT_SYSINFO_EHDR
isn't found and gettimeofday isn't defined.
