Subject: [seccomp]  0eebfed295: kernel_selftests.seccomp.make_fail

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

commit: 0eebfed2954f152259cae0ad57b91d3ea92968e8 ("seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE")
https://git.kernel.org/cgit/linux/kernel/git/kees/linux.git for-next/seccomp

in testcase: kernel_selftests
with following parameters:

	group: kselftests-02

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 8G

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):

	make HOSTCC=gcc-7 CC=gcc-7 ARCH=x86_64 olddefconfig prepare modules_prepare bzImage

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        bin/lkp qemu -k <bzImage> job-script # job-script is attached in this email
