Subject: [LKP] [selftests]  60b119cae8:
 kernel_selftests.tpm2.test_smoke.sh.fail

FYI, we noticed the following commit (built with gcc-7):

commit: 60b119cae86ecb300fa50fd107122e3568156991 ("[PATCH v3] selftests: add TPM 2.0 tests")
url: https://github.com/0day-ci/linux/commits/Jarkko-Sakkinen/selftests-add-TPM-2-0-tests/20190206-002609
base: https://git.kernel.org/cgit/linux/kernel/git/shuah/linux-kselftest.git next

in testcase: kernel_selftests
with following parameters:

	group: kselftests-03

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 4G
