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

commit: 323d73a8ecad22bf3284f11112a7cce576ade6af ("KVM: nVMX: Change KVM_STATE_NESTED_EVMCS to signal vmcs12 is copied from eVMCS")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master

in testcase: kernel_selftests
with following parameters:

	group: kselftests-01

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: 8 threads Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 16G memory

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