Subject: [selftests/tls] cf32526c88: kernel_selftests.net.tls.fail

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

commit: cf32526c8842781e32d6652a1e01e83b20490948 ("selftests/tls: add a test for ULP but no keys")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git pending-fixes

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):


If you fix the issue, kindly add following tag

To reproduce:

        # build kernel
	cd linux
	cp config-5.2.0-08346-gcf32526c884278 .config
	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
