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

commit: 6b6a864bd7d7eb12a82ec6da1c2dd97a43f79449 ("[PATCH v2] KVM: nVMX: Tweak handling of failure code for nested VM-Enter failure")
base: linux-next

in testcase: kernel-selftests
with following parameters:

	group: kselftests-kvm
	ucode: 0x500002c

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.
