Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: 3ca8c91756c3db8101879274075fc0a76b127a52 ("[PATCH v2 4/4] selftests: kvm: Test MSR exiting to userspace")
url: https://github.com/0day-ci/linux/commits/Aaron-Lewis/Test-MSR-exits-to-userspace/20201009-194717
base: https://git.kernel.org/cgit/virt/kvm/kvm.git linux-next

in testcase: kernel-selftests
version: kernel-selftests-x86_64-e8e8f16e-1_20200807
with following parameters:

	group: kselftests-kvm
	ucode: 0xdc

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) i7-6770HQ CPU @ 2.60GHz with 32G memory
